Detailed Description
The present invention will be described in detail with reference to the drawings, which are provided for reference and illustration purposes only and are not intended to limit the present invention.
Fig. 1 is a schematic perspective view of a heat pipe radiator according to the present invention. The present invention is a heat pipe heat sink 1, which comprises a heat pipe 10 and a heat pipe clamping structure 20. The heat pipe 10 is incorporated in the heat pipe holding structure 20. In an embodiment of the present invention, the heat pipe radiator 1 further includes a heat dissipation body 30 and a heat dissipation fan 40. The heat sink 30 includes a plurality of heat dissipation fins 31 and is coupled to one end of the heat pipe 10. The heat dissipation fan 40 is disposed at one side of the heat dissipation body 30 to generate a forced flow and dissipate heat of the heat dissipation body 30, thereby improving heat dissipation efficiency. It is noted that the internal structure of the heat pipe 10 is well known in the art and will not be described in detail herein.
Fig. 2 is a schematic perspective view of a heat pipe clamping structure 20 of a heat pipe heat sink according to the present invention. The heat pipe clamping structure 20 is not limited in the arrangement manner, and mainly penetrates through the heat pipe 10, and can press the heat pipe 10 after being pressed. In the present embodiment, the heat pipe clamping structure 20 is configured as a heat conducting plate, which is not limited in practical implementation.
The heat pipe clamping structure 20 includes a receiving slot 21 and a pair of side wings 22 extending on opposite sides of the receiving slot 21. The receiving cavity 21 includes a bottom wall 211 and two side walls 212 extending from the bottom wall 211. The two sidewalls 212 are extended with two pressing-pulling-piece 23 higher than the surface of the pair of wings 22. In this embodiment, the pair of side wings 22 is formed with a semicircular groove 24 on a side adjacent to each of the pressing pawls 23. In addition, each side wing 22 is provided with a plurality of openings 220 arranged in a straight line for receiving a plurality of locking members (not shown) to position the heatpipe heat sink 1 at a fixed position. In this embodiment, the locking components are configured as mechanism components capable of generating a pressing force, such as a combination of a spring plate and a spring screw, which is not limited in practical implementation.
Please refer to fig. 3 to fig. 6, which are schematic diagrams illustrating the heat pipe and the heat pipe clamping structure of the present invention. The heat pipe clamping structure 20 includes a receiving groove 21, a pair of side wings 22, two pressing pieces 23, and two semicircular grooves 24 disposed on the pair of side wings 22 and adjacent to the two pressing pieces 23.
When the two pressing pieces 23 are pressed, the material at the root of each pressing piece 23 (the portion adjacent to the semicircular groove 24) is pushed and pushed toward each semicircular groove 24. Therefore, the two semicircular grooves 24 serve as material escaping spaces to fill excess material after extrusion when the two pressing pieces 23 are pressed, so as to prevent the two pressing pieces 23 from being pressed and deformed to be accumulated on the surfaces of the side wings 22 or generate an uneven phenomenon. In addition, the semicircular grooves 24 are formed in a semicircular shape to prevent stress concentration, thereby forming a flat surface on the side wings 22.
Furthermore, the heat pipe 10 is inserted into the receiving groove 21 of the heat pipe clamping structure 20, and the cross section of each pressing piece 23 is trapezoidal, circular, square or triangular. Specifically, each of the pressing-pulling-piece 23 extends in a direction away from the surface of each side wing 22 to have an extension height H higher than the surface of each side wing 22. Furthermore, the root of the pressing sheet 23 is defined as the position higher than the surface of each flank 22, and the root of each pressing sheet 23 has a pressing sheet width W, which is greater than 0.01 mm.
Preferably, the extending height H of each pressing piece 23 is greater than 0.03 mm. In addition, the extension width W of each pressing piece 23 is larger than 0.01 mm. In one embodiment of the present invention, specifically, the extending height H of each pressing piece 23 is 0.8mm plus or minus 0.2 mm. The pressing piece width W of each pressing piece 23 is 0.2mm plus or minus 0.2 mm.
More specifically, each of the pressing tabs 23 includes an extending inclined edge 231 adjacent to the semicircular groove 24. The extending bevel edge 231 forms a pressing included angle a with the surface of the side wing 22, and the pressing included angle a is greater than 1 degree. In this embodiment, the pressing included angle a is about 65 degrees plus or minus 3 degrees.
As shown in fig. 5, the heat pipe 10 is disposed in the accommodating groove 21. The two pressing pieces 23 of the heat pipe clamping structure 20 are pressed and embedded into the heat pipe 10 and exposed out of the wall surface of the accommodating groove 21. That is, the two pressing pieces 23 cover a portion of the heat pipe 10 exposed to the accommodating groove 21. Accordingly, the heat pipe 10 can be fixed in the heat pipe clamping structure 20 without loosening. Specifically, the wall thickness T of each pressing piece 23 embedded in the heat pipe 10 after being pressed is greater than 0.01 mm.
It should be noted that the semi-circular groove 24 is filled with a portion of the deformation of the two pressing tabs 23 after pressing to be flush or parallel with the surface of the adjacent side wing 22 and has a flat contact surface to facilitate close contact with a heat generating component.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalent variations using the spirit of the present invention should fall within the scope of the present invention.
