Background
The printed circuit board for the new energy automobile is an important component in an electrical appliance part of the new energy automobile. The printed circuit board for the new energy automobile is a copper-based circuit board, the printed circuit board for the new energy automobile is composed of a copper plate and a circuit layer arranged on the surface of the copper plate, and the circuit layer of the printed circuit board for the new energy automobile is complicated in wiring, so that the circuit layer is extremely high in power consumption and easy to burn. Along with the long-time work of printed circuit board for the new energy automobile, the heat is piled up on the circuit layer in a large number, finally leads to the circuit layer to burn out, has seriously reduced the life of circuit board, and the competitiveness of market also descends gradually. In addition, printed circuit board for new energy automobile adopts the several fix with screw in the quick-witted case usually, when the circuit board needs to be changed, then need unscrew all screws and just can take it off, very big inconvenient maintenance personal operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a compact structure, radiating effect is good, increase of service life, the convenient high radiating printed circuit board for new energy automobile who changes.
The purpose of the utility model is realized through the following technical scheme: the printed circuit board for the new energy automobile with high heat dissipation comprises a base and a heat dissipation structure, wherein a groove is formed in the top surface of the base, a plurality of heat dissipation teeth are welded in the groove and positioned on the bottom surface of the groove, the heat dissipation teeth are longitudinally arranged and extend out of the groove, the printed circuit board is placed at the top of the heat dissipation teeth, four blind holes are arranged on the top surface of the base, the four blind holes are respectively positioned at the four corners of the base, a spring is fixedly arranged in each blind hole and positioned at the bottom of the blind hole, the spring extends outside the blind hole, the heat radiation structure all includes copper and heat pipe, and the copper is on a parallel with the top of base and is located the base top, and a plurality of bar grooves have been seted up at the top of copper, and every bar inslot all inlays and has the heat pipe, and four angles departments that the top of four springs was fixed in the copper respectively support under the spring restoring force of spring and press on printed circuit board's top surface.
The groove is a rectangular groove.
The distance between every two adjacent radiating teeth is equal.
The strip-shaped grooves are all horizontally arranged.
The distance between two adjacent strip-shaped grooves is equal.
The utility model has the advantages of it is following: the utility model discloses compact structure, radiating effect are good, increase of service life, convenient change.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:
as shown in fig. 1 ~ 2, high radiating printed circuit board for new energy automobile, it includes base 1 and heat radiation structure, base 1 has seted up recess 2 on the top surface, and recess 2 is the rectangular channel in this embodiment, and the welding has a plurality of heat dissipation teeth 3 in the recess 2 and on being located its basal surface, and the interval between every two adjacent heat dissipation teeth 3 equals, and heat dissipation teeth 3 vertically sets up, and heat dissipation teeth 3 extends in recess 2 outside, and printed circuit board 9 has been placed at the top of heat dissipation teeth 3, four blind holes 4 have been seted up on base 1's the top surface, and four blind holes 4 are located four corners of base 1 respectively, and every blind hole 4 is interior and be located its bottom and all have set firmly spring 5, and spring 5 extends in blind hole 4 outside, heat radiation structure all includes copper 6 and heat pipe 7, and copper 6 is on a parallel with base 1's top surface and is located base 1 top, and a plurality of bar grooves 8 have been seted up at the top of copper 6, and the equal level in bar groove 8 sets up, and the interval between two adjacent bar grooves 8 equals, and every bar groove 8 all has all had heat pipe 7, and four spring 5's top surface is fixed in four spring 5 tops are.
The working process of the utility model is as follows: after the printed circuit board 9 for the new energy automobile works for a long time, heat is generated on the printed circuit board 9, because the upper part of the printed circuit board 9 is in close contact with the copper plate 6, the heat of the upper part of the printed circuit board 9 is transferred to the copper plate 6 and then transferred to the heat conduction pipe 7 by the copper plate 6, the heat conduction pipe 7 discharges the heat to the outside, meanwhile, because the lower part of the printed circuit board 9 is in contact with the heat dissipation teeth 3, the heat of the lower part of the printed circuit board 9 is transferred to the heat dissipation teeth 3 and then transferred to the outside by the heat dissipation teeth 3, the heat is simultaneously dissipated by the upper part and the lower part, the heat dissipation of the printed circuit board is accelerated, the printed circuit board for the new energy automobile is always in a normal temperature. When 9 damages the time need changing of printed circuit board, maintainer only need upwards mention copper 6, copper 6 and printed circuit board separation, the printed circuit board of damage of taking out that this moment can be quick makes things convenient for subsequent maintenance or change, compares the mode that all screws were twisted out to the tradition, very big improvement maintenance efficiency, alleviateed workman's intensity of labour simultaneously.
