Description
本發明是關於一種顯示裝置,特別是一種具有散熱模組的顯示裝置。The present invention relates to a display device, and more particularly to a display device having a heat dissipation module.
近年來,由於液晶顯示裝置(Liquid Crystal Display,簡稱LCD)具有輕薄的優點,其係廣泛應用於電腦、電視以及行動電話等各種電子產品上以用於顯示圖像。詳細來說,液晶顯示裝置主要包含一背光模組(Backlight Module)以及一面板(Panel)。背光模組發出光線至面板,面板用以轉換光線而共同形成所欲之顏色以及圖像。其中,背光模組所使用之光源裝置,則直接影響背光模組之效能與組裝成本。而發光二極體(Light Emitting Diode,簡稱LED)由於具有亮度高、體積小以及耗能少等優勢,因此成為大多數液晶顯示器使用的光源之一。此外,相較於直下式背光模組,採用發光二極體的側光式背光模組因為可具有較薄之厚度,以使液晶顯示裝置達到高亮度以及窄邊框的特色而受到重視。In recent years, liquid crystal displays (LCDs) have been widely used in various electronic products such as computers, televisions, and mobile phones for displaying images because of their slimness and lightness. In detail, the liquid crystal display device mainly includes a backlight module and a panel. The backlight module emits light to the panel, and the panel converts light to form a desired color and image. Among them, the light source device used in the backlight module directly affects the performance and assembly cost of the backlight module. Light Emitting Diode (LED) is one of the light sources used in most liquid crystal displays because of its high brightness, small size, and low power consumption. In addition, compared with the direct type backlight module, the edge-lit backlight module using the light-emitting diode has been paid attention to because of its thin thickness, so that the liquid crystal display device achieves high brightness and narrow frame.
然而,發光二極體發光時亦會產生大量熱量。當液晶顯示裝置採用發光二極體作為光源時,發光二極體運作所產生的熱量會使整體液晶顯示裝置的溫度升高,容易影響 液晶顯示裝置的正常運作,甚至導致損壞。However, a large amount of heat is generated when the light-emitting diode emits light. When the liquid crystal display device uses the light-emitting diode as the light source, the heat generated by the operation of the light-emitting diode causes the temperature of the entire liquid crystal display device to rise, which is easy to affect. The normal operation of the liquid crystal display device even causes damage.
目前業者研發出一種散熱結構,以熱接觸的方式連接背光模組,用以排除背光模組運作時的熱量。當液晶顯示裝置畫面越大、亮度越高且邊框越窄的情況下,散熱結構連接背光模組的面積就越小,且背光模組所產生的熱量也越高,散熱結構則無法有效地排除熱量。若增加散熱結構的厚度以及延伸其長度,將導致散熱結構的成本大幅增加,且增加整體的厚度。At present, the industry has developed a heat dissipation structure that connects the backlight module in a thermal contact manner to eliminate heat during operation of the backlight module. When the screen of the liquid crystal display device is larger, the brightness is higher, and the frame is narrower, the area of the heat dissipation structure connected to the backlight module is smaller, and the heat generated by the backlight module is higher, and the heat dissipation structure cannot be effectively excluded. Heat. Increasing the thickness of the heat dissipation structure and extending its length will result in a substantial increase in the cost of the heat dissipation structure and an increase in the overall thickness.
是以,目前急需一種散熱結構,在維持液晶顯示裝置具有高亮度、窄邊框以及薄厚度特徵的情況下,能有效排除液晶顯示裝置運作時所產生的熱量。Therefore, there is an urgent need for a heat dissipating structure, which can effectively eliminate the heat generated when the liquid crystal display device operates while maintaining the high brightness, narrow bezel, and thin thickness characteristics of the liquid crystal display device.
鑒於以上的問題,本發明揭露一種顯示裝置及其散熱模組,藉以解決顯示裝置運作時散熱的問題。In view of the above problems, the present invention discloses a display device and a heat dissipation module thereof, thereby solving the problem of heat dissipation during operation of the display device.
本發明的一實施例揭露一種顯示裝置,其包含一背框、一導光板、一面板模組、一光源模組以及一散熱模組。背框具有相對的一第一表面與一第二表面以及第一表面與第二表面之間的一側邊。導光板設置於第二表面並具有一入光面。面板模組設置於導光板上。光源模組位於背框的側邊,並面對入光面。散熱模組接觸於光源模組並包含一本體、一第一延伸板以及一第二延伸板。本體位於背框的側邊並接觸於光源模組,且本體具有沿側邊方向延伸的一縱向流道。第 一延伸板自本體向外延伸並位於背框的第一表面。第二延伸板自本體向外延伸。第一延伸板介於第一表面以及第二延伸板之間,且第一延伸板以及第二延伸板之間相隔一距離以形成連通縱向流道的至少一橫向流道。An embodiment of the invention includes a back frame, a light guide plate, a panel module, a light source module, and a heat dissipation module. The back frame has a first surface and a second surface opposite to each other and a side between the first surface and the second surface. The light guide plate is disposed on the second surface and has a light incident surface. The panel module is disposed on the light guide plate. The light source module is located on the side of the back frame and faces the light entrance surface. The heat dissipation module is in contact with the light source module and includes a body, a first extension plate and a second extension plate. The body is located at a side of the back frame and is in contact with the light source module, and the body has a longitudinal flow path extending along a side direction. First An extension plate extends outwardly from the body and is located on the first surface of the back frame. The second extension plate extends outward from the body. The first extension plate is interposed between the first surface and the second extension plate, and the first extension plate and the second extension plate are separated by a distance to form at least one lateral flow path connecting the longitudinal flow channels.
根據本發明揭露的顯示裝置中,當光源模組運作產生熱量時,熱量會經由熱傳導的方式傳遞至散熱模組的本體。而後,熱量可於本體的縱向流道沿著側邊方向而藉由熱對流的方式由縱向流道內的氣流由下往上移除。再者,傳遞至本體的其餘熱量亦會經由熱傳導的方式傳遞至第一延伸板與第二延伸板,再藉由熱傳導的方式向第一延伸板與第二延伸板的週遭以進行散熱。由於第一延伸板與第二延伸板之間具有與縱向流道夾角的橫向流道,氣流可自各橫向流道進入至縱向流道,加速縱向流道的氣流流動,進而提升熱傳導效率。如此,在不需要提升散熱模組的厚度以及長度的情況下,可加速散熱模組的整體散熱效率,進而節省生產材料成本。According to the display device disclosed in the present invention, when the light source module operates to generate heat, heat is transferred to the body of the heat dissipation module via heat conduction. Then, heat can be removed from the bottom to the top in the longitudinal flow path by heat convection in the longitudinal direction of the body along the side direction. Furthermore, the remaining heat transferred to the body is also transferred to the first extension plate and the second extension plate via heat conduction, and then radiated to the circumference of the first extension plate and the second extension plate by heat conduction. Since the first extension plate and the second extension plate have a lateral flow path at an angle with the longitudinal flow path, the air flow can enter from the lateral flow channels to the longitudinal flow path, accelerating the flow of the air flow in the longitudinal flow path, thereby improving the heat transfer efficiency. In this way, the overall heat dissipation efficiency of the heat dissipation module can be accelerated without increasing the thickness and length of the heat dissipation module, thereby saving production material costs.

第一延伸板152自本體151向外延伸並位於背框11的第一表面111上,且第一延伸板152介於第一表面111以及第二延伸板153之間。第一延伸板152具有彼此相對的一第三表面1521以及一第四表面1522,第三表面1521面對背框11的第一表面111。第二延伸板153具有彼此相對的一第五表面1532以及一第六表面1533,第五表面1532面對第一延伸板152的第四表面1522。在本實施例以及部分的其他實施例中,顯示裝置1更包含一固定件16,散熱模組15的第一延伸板152藉由固定件16固定設置於背框11的第一表面111上。其中,固定件16包含螺絲、鉚釘、焊接、或其它合適的固定件。在本發明中,第一延伸板152以及第二延伸板153 之間相隔第二距離D2以形成連通縱向流道1511的多條橫向流道1531。其中,橫向流道1531也呈現中空狀。散熱模組15可選擇性地更包含多條肋條154,分別介於第一延伸板152與第二延伸板153之間,以將第一延伸板152與第二延伸板153之間區隔出多個橫向流道1531,且也可以防止第一延伸板152以及第二延伸板153發生凹陷,並以支撐維持第二距離D2,來讓橫向流道1531暢通。橫向流道1531各具有相對的一入風口1531a以及一出風口1531b,出風口1531b連通縱向流道1511。同時,橫向流道1531以及縱向流道1511之間分別夾有一角度θ,此角度θ可小於或等於九十度且大於零度。The first extension plate 152 extends outward from the body 151 and is located on the first surface 111 of the back frame 11 , and the first extension plate 152 is interposed between the first surface 111 and the second extension plate 153 . The first extension plate 152 has a third surface 1521 and a fourth surface 1522 opposite to each other, and the third surface 1521 faces the first surface 111 of the back frame 11. The second extension plate 153 has a fifth surface 1532 and a sixth surface 1533 opposite to each other, and the fifth surface 1532 faces the fourth surface 1522 of the first extension plate 152. In this embodiment and some other embodiments, the display device 1 further includes a fixing member 16 . The first extension plate 152 of the heat dissipation module 15 is fixedly disposed on the first surface 111 of the back frame 11 by the fixing member 16 . Wherein the fixing member 16 comprises a screw, a rivet, a weld, or other suitable fixing member. In the present invention, the first extension plate 152 and the second extension plate 153 The second distance D2 is spaced apart to form a plurality of lateral flow passages 1531 that communicate with the longitudinal flow passages 1511. Among them, the lateral flow path 1531 also has a hollow shape. The heat dissipation module 15 can further include a plurality of ribs 154 respectively between the first extension plate 152 and the second extension plate 153 to separate the first extension plate 152 and the second extension plate 153. The plurality of lateral flow passages 1531 can also prevent the first extension plate 152 and the second extension plate 153 from being recessed, and maintain the second distance D2 with the support to make the lateral flow passage 1531 unblocked. The lateral flow passages 1531 each have an opposite air inlet 1531a and an air outlet 1531b, and the air outlet 1531b communicates with the longitudinal flow passage 1511. Meanwhile, an angle θ is sandwiched between the lateral flow path 1531 and the longitudinal flow path 1511, and the angle θ may be less than or equal to ninety degrees and greater than zero degrees.
是以,藉由散熱模組15接觸於光源模組14,當光源模組14運作發光而產生熱量時,熱量會經由熱傳導的方式傳遞至散熱模組15的本體151。而後,熱量可於本體151的縱向流道1511沿著側邊方向(例如本實施例之軸向Z)藉由熱對流的方式由縱向流道1511內的氣流A由下往上帶走,例如:第3圖所示的顯示裝置1中的右下角往右上角或左下角往左上角流動,但不限於此。再者,傳遞至本體151的熱量亦會經由熱傳導的方式傳遞至第一延伸板152與第二延伸板153,再藉由熱傳導的方式向第一延伸板152與第二延伸板153的週遭以進行散熱。由於第一延伸板152與第二延伸板153之間具有多個與縱向流道1511夾有角度θ的橫向流道1531,氣流B可自各橫向流道1531的入風口1531a進入,再從出風 口1531b流至縱向流道1531。藉由煙囪效應(Stack Effect,或Chimney Effect),橫向流道1531的氣流B進入縱向流道1511,加速縱向流道1511的氣流A從下往上(『第3圖』所示方向)流動,進而提升熱傳導效率。如此,可加速散熱模組15的整體散熱效率。Therefore, when the heat dissipation module 15 is in contact with the light source module 14, when the light source module 14 operates to emit heat, heat is transferred to the body 151 of the heat dissipation module 15 via heat conduction. Then, heat can be carried away from the bottom to the top of the longitudinal flow path 1511 of the body 151 in the lateral direction (for example, the axial direction Z of the present embodiment) by the air flow A in the longitudinal flow path 1511 by, for example, heat convection, for example, : The lower right corner of the display device 1 shown in FIG. 3 flows to the upper right corner or the lower left corner to the upper left corner, but is not limited thereto. Moreover, the heat transferred to the body 151 is also transferred to the first extension plate 152 and the second extension plate 153 via heat conduction, and then is thermally conducted to the circumference of the first extension plate 152 and the second extension plate 153. Cool down. Since the first extension plate 152 and the second extension plate 153 have a plurality of lateral flow paths 1531 at an angle θ with the longitudinal flow passages 1511, the air flow B can enter from the air inlets 1531a of the lateral flow passages 1531, and then from the air outlet. The port 1531b flows to the longitudinal flow path 1531. By the stack effect (Chimney Effect), the airflow B of the lateral flow path 1531 enters the longitudinal flow path 1511, and the airflow A of the accelerated longitudinal flow path 1511 flows from the bottom to the top (the direction shown in FIG. 3). Thereby improving the heat transfer efficiency. In this way, the overall heat dissipation efficiency of the heat dissipation module 15 can be accelerated.
在本實施例以及部分的其他實施例中,第一板件1513以及第二板件1514之間的第一距離D1大於第一延伸板152以及第二延伸板153之間的第二距離D2。進一步來說,橫向流道1531的截面積係盡可能小於縱向流道1511的截面積。如此,以令截面積較大的縱向流道1511內所產生的氣流A成為主氣流,而利於牽引截面積較小的橫向流道1531內之氣流B,藉以加速氣流流速,以提升熱傳導的效果。In this embodiment and some other embodiments, the first distance D1 between the first plate member 1513 and the second plate member 1514 is greater than the second distance D2 between the first extension plate 152 and the second extension plate 153. Further, the cross-sectional area of the lateral flow path 1531 is as small as possible smaller than the cross-sectional area of the longitudinal flow path 1511. In this way, the airflow A generated in the longitudinal flow passage 1511 having a large cross-sectional area becomes the main airflow, and the airflow B in the lateral flow passage 1531 having a small cross-sectional area is facilitated to accelerate the airflow velocity to enhance the heat conduction effect. .
在本實施例以及部分的其他實施例中,本體151及第一延伸板152的材質是金屬或合金。當本體151及第一延伸板152的材質是金屬或合金時,可有效提升熱傳導的速度。而第二延伸板153以及肋條154的材質是塑膠,肋條154以及第二延伸板153係一體成型,且肋條154遠離第二延伸板153的一端係貼合於第一延伸板152。於其它實施例時,肋條154可組裝於第二延伸板153上。再者,當第二延伸板153的材質是塑膠時,可減輕重量並有效降低成本。此外,第一延伸板152與第二延伸板153之間的第二距離D2的長度約是1公釐至2公釐,而散熱模組15的寬度約略等於面板模組13寬度 的五分之一。然而,上述的材質、尺度以及製造組成關係非用以限定本發明。In other embodiments of this embodiment and some of the embodiments, the body 151 and the first extension plate 152 are made of metal or alloy. When the material of the body 151 and the first extension plate 152 is a metal or an alloy, the speed of heat conduction can be effectively improved. The second extension plate 153 and the rib 154 are made of plastic, and the rib 154 and the second extension plate 153 are integrally formed, and one end of the rib 154 away from the second extension plate 153 is attached to the first extension plate 152. In other embodiments, the ribs 154 can be assembled to the second extension panel 153. Moreover, when the material of the second extension plate 153 is plastic, the weight can be reduced and the cost can be effectively reduced. In addition, the length of the second distance D2 between the first extension plate 152 and the second extension plate 153 is about 1 mm to 2 mm, and the width of the heat dissipation module 15 is approximately equal to the width of the panel module 13 One-fifth. However, the above materials, dimensions, and manufacturing composition relationships are not intended to limit the present invention.
此外,本實施例的散熱模組15係位於整體顯示裝置1的側端,以使縱向流道1511的延伸方向實質上平行於重力方向。然而,於其他實施例中,散熱模組15係可位於顯示裝置1的頂端或底端,以接觸位於頂端或底端的光源模組14。此時,橫向流道1531係沿軸向Z延伸,而縱向流道1511沿軸向X延伸。如此,散熱模組15亦可藉由橫向流道1531以及縱向流道1511的氣流導引而進行散熱。In addition, the heat dissipation module 15 of the present embodiment is located at the side end of the entire display device 1 such that the extending direction of the longitudinal flow path 1511 is substantially parallel to the direction of gravity. However, in other embodiments, the heat dissipation module 15 can be located at the top or bottom end of the display device 1 to contact the light source module 14 at the top or bottom end. At this time, the lateral flow path 1531 extends in the axial direction Z, and the longitudinal flow path 1511 extends in the axial direction X. In this way, the heat dissipation module 15 can also dissipate heat by the air flow guiding of the lateral flow path 1531 and the longitudinal flow path 1511.
請參照『第4圖』,其係為根據本發明另一實施例的顯示裝置的剖切示意圖。本實施例與上述實施例類似,其差異在於本實施例的散熱模組25中,本體251形成的橫向流道2531以及縱向流道2511之間分別夾有一角度θ1,此角度θ1約等於九十度。是以,氣流B亦可經由肋條254之間的橫向流道2531而自外界進入縱向流道2511,以提升縱向流道2511的氣流A速率,進而提升熱傳導速率,提升整體散熱效率。Please refer to FIG. 4, which is a schematic cross-sectional view of a display device according to another embodiment of the present invention. The embodiment is similar to the above embodiment, and the difference is that in the heat dissipation module 25 of the embodiment, the lateral flow path 2531 and the longitudinal flow path 2511 formed by the body 251 are respectively provided with an angle θ1, and the angle θ1 is approximately equal to ninety. degree. Therefore, the air flow B can also enter the longitudinal flow path 2511 from the outside through the lateral flow path 2531 between the ribs 254 to increase the air flow A rate of the longitudinal flow path 2511, thereby increasing the heat conduction rate and improving the overall heat dissipation efficiency.
請參照『第5圖』,其係為根據本發明又一實施例的顯示裝置的剖切示意圖。本實施例與上述實施例類似,其差異在於散熱模組35不具有肋條,而本體351的橫向流道3531僅具有一橫向流道3531。橫向流道3531內的氣流B可不需要藉由肋條導引而直接流動至縱向流道3511。如此,亦可 加速縱向流道3511的氣流A流動。Please refer to FIG. 5, which is a schematic cross-sectional view of a display device according to still another embodiment of the present invention. This embodiment is similar to the above embodiment, except that the heat dissipation module 35 does not have ribs, and the lateral flow path 3531 of the body 351 has only one lateral flow path 3531. The air flow B in the lateral flow path 3531 can flow directly to the longitudinal flow path 3511 without being guided by the ribs. So, you can The flow A of the longitudinal flow path 3511 is accelerated.
綜合上述,本發明揭露的顯示裝置中,當光源模組運作產生熱量時,熱量會經由熱傳導的方式傳遞至散熱模組的本體,而後,熱量可於本體的縱向流道沿著側邊方向而藉由熱對流的方式由縱向流道內的氣流由下往上移除。再者,傳遞至本體的其餘熱量亦會經由熱傳導的方式傳遞至第一延伸板與第二延伸板,再藉由熱傳導的方式向第一延伸板與第二延伸板的週遭以進行散熱。由於第一延伸板與第二延伸板之間具有多個與縱向流道夾角的橫向流道,氣流可自各橫向流道進入至縱向流道,加速縱向流道的氣流流動,進而提升熱傳導效率。如此,在不需要提升散熱模組的厚度以及長度的情況下,可加速散熱模組的整體散熱效率,進而節省生產材料成本。In summary, in the display device disclosed in the present invention, when the light source module operates to generate heat, heat is transferred to the body of the heat dissipation module via heat conduction, and then the heat can be along the longitudinal direction of the body along the side direction. The heat flow in the longitudinal flow path is removed from the bottom up by means of thermal convection. Furthermore, the remaining heat transferred to the body is also transferred to the first extension plate and the second extension plate via heat conduction, and then radiated to the circumference of the first extension plate and the second extension plate by heat conduction. Since the first extension plate and the second extension plate have a plurality of lateral flow paths at an angle with the longitudinal flow passage, the air flow can enter from the lateral flow passages to the longitudinal flow passages, accelerating the flow of the longitudinal flow passages, thereby improving the heat transfer efficiency. In this way, the overall heat dissipation efficiency of the heat dissipation module can be accelerated without increasing the thickness and length of the heat dissipation module, thereby saving production material costs.
