Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation structures and relates to a highly efficient and compact heat dissipation structure. Background Art
[0002] Usually, the motor controller and generator controller are assembled on the vehicle as independent components. The two controllers take up a large space when stacked together, and the overall space utilization is low. The positive and negative ends of the high-voltage connector are reused, and the inlet and outlet connections are complicated, which increases material and labor costs, increases quality and safety risks, and reduces the service life of the vehicle.
[0003] Patent No. CN201922323487.8 discloses a compact power module heat dissipation structure, including a box body. When the motor controller and the generator controller are integrated into one controller in this technical solution, a first cavity is added inside the box body to connect with the second cavity, the end of the first cavity is connected to the water inlet pipe nozzle, and the end of the second cavity is installed with the water outlet pipe nozzle. The water channel system is the water inlet pipe nozzle. The first cavity for heat dissipation of the motor controller is provided with a water outlet at the tail of the first cavity. The water then flows to the second cavity for heat dissipation of the generator. The other end of the cavity is connected to the water pipe nozzle. The heat dissipation cavity is symmetrical on both sides of the motor controller and the generator controller. After water channel heat dissipation simulation, the outlet temperature section fully meets the use requirements. In addition, the angle design of the slope on both sides is also relatively reasonable, which plays an important role in improving the flow resistance.
[0004] The above-disclosed heat dissipation structure has the disadvantages of not having good thermal conductivity and using water cooling, which is prone to condensation and has potential safety hazards in its circuit connection. Therefore, we design an efficient and compact heat dissipation structure. Summary of the invention
