Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to an aluminum battery heat dissipation shell for an automobile. Background Art

[0002] In a broad sense, a hybrid vehicle refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. The second drive energy of today's hybrid vehicles is driven by electric energy. In order to protect the battery, a casing is required. The battery is prone to generate heat when in use. If the heat dissipation effect is not good, it is easy to cause battery damage or even combustion.

[0003] China Patent Network discloses a heat dissipation structure of a battery box for new energy vehicles (publication number: CN 212517317U), including a battery box, a fan, an air duct, a sealing plate, a honeycomb heat dissipation plate, a battery assembly, and an isolation plate; the air duct is installed on one side of the battery box, and the isolation plate is installed on the bottom of the battery box, and the battery assembly is installed on the isolation plate, and the honeycomb heat dissipation plate is installed on the battery assembly. The heat dissipation structure of the battery box for new energy vehicles drives air into the air duct through the fan, and enters the battery box through the exhaust port, then enters between the battery assemblies from the honeycomb heat dissipation plate, and enters the isolation plate with the heat generated by the battery assembly, and finally is discharged from the heat dissipation port of the battery box, so that the air circulates inside the battery box, extracts the heat therein, effectively cools the battery assembly, and thus protects the battery box.

[0004] From the above-mentioned drawings, it can be seen that the battery components of the prior art are directly stacked in the battery box, which will make the battery components fit together, causing the heating surfaces to be close, thereby affecting the heat dissipation effect. At the same time, when the car shakes during driving, the battery components in the battery box will collide with each other, which is easy to cause damage and poses safety problems. Therefore, there is room for improvement. Utility Model Content

[0010] The beneficial effects of adopting the above technical solution are:

[0011] 1. Divide the battery components by setting the installation grooves, and place the battery components to produce fit or collision.

[0012] 2. The cooling fan on the top cover rotates to generate suction to absorb the heat generated by the battery assembly in the installation slot, and then introduces external cold air into the air inlet cavity through the air inlet. Under the action of suction, the air is dispersed to each installation slot in the air inlet cavity, thereby dissipating the heat of the battery assembly. The cold air enters from the bottom and the hot air is discharged from the top, making the heat dissipation effect better.

[0013] 3. The buffer assembly can reduce the up and down shaking of the battery assembly, and the support frame can support the four sides of the battery assembly, thereby effectively preventing the battery assembly from shaking in the installation slot and preventing damage to the battery assembly due to collision.
