Embodiment 1

[0049] In this embodiment, the welding area 15 of the power module is arranged in three pieces, and the capacitor module installation groove 11 is the center of the square arrangement, which improves the compactness of the present invention. The spoiler 141 is a protrusion arranged on the inner wall of the channel cavity. The protrusion is a columnar spoiler, which has a simple structure and is easy to produce. The round hole is provided with an internal thread, and the internal thread goes straight to the upper end surface of the round hole, which is convenient for use with the faucet. The insulating material is insulating plastic. The through hole is provided with an output screw counterbore on the bearing surface of the capacitor module. The side of the positioning column 5821 is provided with reinforcing ribs to increase the stability of the bracket. The metal shell is made of aluminum alloy. The connecting hole 541 is fixedly connected to the output screw 542 by weldi...

Embodiment 2

[0051] In this embodiment, the spoiler 141 is a protrusion provided on the inner wall of the channel cavity. The protrusion is a columnar spoiler, and the spoiler is arranged along the direction of the flow channel, which can effectively spoil the cooling liquid. The two runner ports 13 are arranged on one side of the bearing surface. The installation hole is provided with an installation counterbore on the assembly surface of the heat dissipation plate, which is beneficial to the integrity of assembly. The capacitor installation surface is evenly provided with more than one capacitor installation position for installing electrolytic capacitors 57 . The capacitor mounting surface is provided with a capacitor support 58 tangentially, and the capacitor support 58 is provided with a capacitor perforation 581 through which the electrolytic capacitor 57 passes. The connecting hole 541 is fixedly connected to the output screw 542 through screw locking. The flatness of the welding...

Embodiment 3

[0053] In this embodiment, the spoiler 141 is a corrugated spoiler arranged on the inner wall of the flow channel cavity, and the spoiler is arranged along the direction of the flow channel, which can effectively spoil the cooling liquid; the circular hole There is a horseshoe-shaped boss under the internal thread, and the horseshoe-shaped opening faces the flow channel. After the water nozzle is screwed down, the lower end surface of the water nozzle contacts the horseshoe-shaped boss, and the cooling medium in the water nozzle enters the flow channel cavity 14 along the horseshoe-shaped direction. The two runner ports 13 are arranged on one side of the assembly surface. The bracket 3 is provided with reinforcing ribs to increase stability. The assembly surface of the heat dissipation plate is provided with a glue groove 36 along the periphery of the power module installation position. The height of the capacitor support 58 is greater than the depth formed by bending the pos...

Abstract

The invention discloses a 48V BSG motor integrated inverter, which comprises a heat dissipation plate, wherein the upper end face of the heat dissipation plate is a bearing face, the lower end face of the heat dissipation plate is an assembling face, a capacitor module mounting groove is formed in the middle of the bearing face, two output screw rod receding holes are separately formed in the front of one end of the capacitor module mounting groove, flow channel openings are formed near the two output screw rod receding holes respectively, a flow channel cavity arranged around the capacitor module mounting groove is formed between the two flow channel openings in a communicated mode, a power module welding area is arranged on the bearing face above the flow channel cavity, a power module is welded to the power module welding area, a bracket is installed above the heat dissipation plate and made of an insulating material, and is provided with a capacitor module, and a PCB module is arranged below the heat dissipation plate. Through the integrated design of the heat dissipation plate, the power module, the bracket, the capacitor module and the PCB module, the structure compactness and shock resistance are both considered while the requirements of a 48V BSG motor inverter are met.

Description

technical field [0001] The invention belongs to the technical field of BSG motor inverters, and in particular relates to a 48V BSG motor integrated 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 technology, in order to achie...
