Embodiment 1
[0015] A pin-type power single-tube integrated structure applied to electric vehicle electronic control products, such as figure 1 As shown, the pin-type power device is firstly crimped to the metal carrier 102 through a pressing sheet or a pressing bar, and an insulating and heat-conducting gasket 103 is provided between the power device and the metal carrier 102; then the power device The pins and the bus capacitor 104 are welded on the thick copper PCB 105; finally, the metal carrier plate integrated with the thick copper PCB is crimped onto the heat dissipation cold plate 106, and the gap between the metal carrier plate 102 and the heat dissipation cold plate 106 is Coated with thermal conductive silicone grease 107.
[0016] Compared with the packaged power module, the price is low, the design flexibility is greatly improved, the feasibility of selective soldering or wave soldering of the single power tube is greatly increased, the weight is light, the heat capacity of th...
