Embodiment 1

[0039] In this embodiment, the height of the positioning boss 3 of the capacitor module is 3.4 mm, which not only ensures the glue filling effect, but also does not affect the thickness of the cooling plate body or the space utilization rate of the inverter. The positioning boss 3 of the capacitor module is provided with an escape notch 31 for better matching with the capacitor module. The upper end surface of the positioning boss 3 of the capacitor module is provided with an internally threaded hole 33 for fixing with the capacitor module. The flatness of the welding area 131 of the power module is 0.4 mm to achieve a better welding effect.

[0040]Processing method: In this embodiment, the processing is divided into two components: the heat sink body and the cover plate 13. The cover plate 13 adopts a stamping process, and the heat sink body adopts a die-casting process. When die-casting the heat sink body, the spoiler part 121 and the spoiler part 121 are die-cast at the sa...

Embodiment 2

[0042] In this embodiment, the height of the positioning boss 3 of the capacitor module is 5mm, which not only ensures the glue filling effect, but also does not affect the thickness of the cooling plate body or the space utilization rate of the inverter. The U-shaped runner groove 12 is provided with a spoiler 121, and the spoiler 121 is fixed on the bottom of the U-shaped runner groove 12 by welding, which can enhance the disturbance effect of the cooling medium fluid, enhance the heat dissipation effect, and ensure the normal operation of the power module. The spoiler part 121 is a plate-shaped protrusion, and the spoiler part 121 is arranged in the direction of the U-shaped runner groove 12; the upper end surface of the capacitor module positioning boss 3 is provided with a capacitor module positioning column 32, and the capacitor module The upper end surface of the module positioning column 32 is provided with an internal thread hole 33, which is convenient for adapting an...

Embodiment 3

[0045] In this embodiment, the height of the positioning boss 3 of the capacitor module is 3.7mm, which not only ensures the glue filling effect, but also does not affect the thickness of the cooling plate body or the space utilization rate of the inverter. The assembly surface 2 is provided with a PCB installation limit wall 22 in a closed loop along the end surface contour, which can effectively realize the installation and positioning of the PCB module, and facilitate the protection of the PCB module by filling glue. The surface electroplating treatment is nickel plating, which is used to improve the weldability between the heat sink body and the power module and the overall corrosion resistance of the heat sink body. The flatness of the welding area 131 of the power module is 0.25 mm to achieve better welding effect.

[0046] Processing method: The difference between this embodiment and the above-mentioned embodiment is that the corrugated heat dissipation ribs are stamped...

Abstract

The invention relates to a heat dissipation plate of a BSG motor inverter. The heat dissipation plate comprises a heat dissipation plate body; the upper end surface of the heat dissipation plate body is a bearing surface; the lower end surface of the heat dissipation plate body is an assembling surface; the middle part of the bearing surface is provided with a capacitor module installation groove; the periphery of the capacitor module installation groove is provided with a U-shaped flow channel groove; the U-shaped flow channel groove is provided with a cover plate in a sealing manner; flow channel openings are formed in the two ends of the U-shaped flow channel groove at the assembling surface; the groove wall and the groove bottom of the capacitor module installation groove are sealed and free of holes; and a capacitor module positioning boss is arranged at the groove bottom of the capacitor module installation groove. The invention further discloses a processing method of the heat dissipation plate of the BSG motor inverter. The groove wall and the groove bottom of the capacitor module installation groove are sealed without holes, and the capacitor module positioning boss is arranged, so that glue leakage of the heat dissipation plate during glue pouring of the capacitor module is effectively prevented, and the problem that the glue pouring process is poor in effect is solved.

Description

technical field [0001] The invention belongs to the technical field of BSG motor inverters, and in particular relates to a cooling plate and a processing method of a BSG motor inverter. Background technique [0002] Energy saving and emission reduction is the common responsibility of all mankind, and it is also the strong desire of most members of society. In the context of the depletion of fossil fuels and the rapid development of automobile technology, the country has increasingly stringent requirements on automobile fuel consumption and emissions. Although BSG technology is not as good as fuel cell and pure electric technology in terms of energy saving and emission reduction effect or advanced level, this technology is gradually being favored by industry experts and may occupy the energy saving and reducing power of traditional power vehicles for a long time in the future. The status of the mainstream technology, because any kind of energy-saving and emission-reduction t...
