The orientation or position relationship of the instructions such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown is for only for ease of description the utility model and simplifies description rather than instruction or imply signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that this practicality
New limitation.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model
Dress ", " connected ", " setting " should be interpreted broadly, for example, it may be being fixedly linked, setting or be detachably connected, set
It puts or is integrally connected, set.For the ordinary skill in the art, it can understand that above-mentioned term exists with concrete condition
Concrete meaning in the utility model.
As shown in Figure 1, a kind of cooling circuit board of the utility model, described to dissipate including circuit board body 3 and heat sink 7
Hot plate 7 is arranged at 3 lower end of circuit board body, is arranged in parallel between the two, and the length of heat sink 7 is less than the length of circuit board body 3
It spends, is covered with the through hole 2 for welding electronic component pin in circuit board body 3, a pad 1 is fixedly mounted in through hole 2, radiate
7 surface of plate is right against at pad 1 and a metal tube 10 is fixedly mounted, and the diameter of metal tube 10 is identical with the diameter of pad 1, metal
The bottom surface of the equal pad 1 of top surface of pipe 10 offsets.
A fixed block 5 is fixedly mounted on four angles on 7 surface of heat sink, a slot is equipped on 5 surface of fixed block, electricity
Road plate body 3 is right against at slot and an inserted link 4 is fixedly mounted, and 4 one end of inserted link is inserted into corresponding slot, fixed block 5
Bottom surface of the top surface with circuit board body 3 offset.
It is covered with heat emission hole 9 on heat sink 7, the longitudinally fixed a piece of above radiating fin leaf 8 of installation on 7 bottom surface of heat sink；Electricity
A mounting hole 6 is equipped on four angles of road plate body 3.
Operation principle：In welding pin, heat sink can be removed from circuit board lower end so that pin can pass through through hole,
Nor affect on welding to pin simultaneously, after finishing, by the splicing of heat sink again in circuit board lower end, and can make metal tube with
Welding offsets, so that the heat that electronic component generates can be directly transferred to along pad in metal tube, the heat on metal tube
Amount then can be quickly transferred on heat sink, can quickly be dispersed heat dissipation by the radiating fin leaf on heat sink, due to heat dissipation
There is gap between plate and circuit board so that air can be between the two by that can take away the heat of a part, add heat dissipation
Effect.
The beneficial effects of the utility model are：The utility model is simple in structure, easy to use, and each installation is on circuit boards
Electronic component can by heat dissipation quickly disperse, add radiating rate, avoid and burn.
