Problems solved by technology
[0005] However, in the above technical solution, the heat generated by the battery is conducted to the walls on both sides of the battery box through the heat conducting fins, and then the heat is taken away by the water in the flow channels on both sides. This structure cannot effectively reduce the temperature of the heat sink in the middle section, resulting in The heat sink is always in a high temperature state, which cannot achieve the heat dissipation effect on the middle battery

The invention discloses an interlayer type new energy automobile battery pack heat dissipation system, relates to the technical field of new energy automobiles, and aims to solve the technical problem of incomplete heat dissipation of a heat dissipation device. The technical scheme is characterized in that a left cooling plate, a right cooling plate and a plurality of middle section cooling plates arranged between the left cooling plate and the right cooling plate are inserted into a bottom plate; the interiors of the left cooling plate, the right cooling plate and the middle-section cooling plate are hollow, and the sections of the left cooling plate, the right cooling plate and the middle-section cooling plate are wavy; a left water inlet hole and a left water outlet hole are formed in the sides, close to the middle section cooling plate, of the two ends of the left cooling plate respectively, and the left water inlet hole and the left water outlet hole are communicated with the interior of the left cooling plate; a left water inlet pipe is arranged at the left water inlet hole, and a left water outlet pipe is arranged at the left water outlet hole. The invention aims to provide the new energy automobile battery pack heat dissipation system which is low in transportation cost and more comprehensive in heat dissipation.
Description
Technical field [0001] The present invention relates to a technical field of new energy vehicles, and more particularly, it relates to a new type energy barrier automotive battery pack cooling system. Background technique [0002] Electric car battery divided into two categories, batteries and fuel cells. Applicable to pure electric vehicle batteries, including lead-acid batteries, nickel-hydrogen batteries, sodium sulfur batteries, secondary lithium batteries, air batteries, ternary lithium batteries, when the motor vehicle is running easy to produce a lot of heat battery. At present, the electric vehicle battery cooling method are mainly two kinds of air cooling and water cooling; air cooling, although simple, but since the specific heat capacity of air is small, it is difficult to meet the cooling requirements of the high temperature of the battery; water cooling the air-cooling capacity than there are obvious advantages, can satisfy the cooling requirements of the battery. Ho...
