A battery box with automatic cooling function

Abstract

The invention discloses a battery case with automatic heat dissipation function, comprising a heat dissipation base, a case body is installed on the heat dissipation base, and three first-stage heat exchange tubes arranged separately are installed in the case body, three The first-stage heat exchange tubes are connected through first-stage connecting tubes, three second-stage heat exchange tubes are installed in the box, and the second-stage heat exchange tubes are connected through second-stage connecting tubes. The inner wall of the box is fixedly connected with a first hollow cylinder, a first spring is fixed between the first piston and the inner top of the first hollow cylinder, and the first-stage heat exchange tubes and the second-stage heat exchange tubes pass through respectively The first short tube and the second short tube communicate with the first hollow cylinder. The invention can not only perform frequency conversion processing on the water pump to realize heat exchange and heat dissipation of the heat in the box, but also reduce the loss of electric power. Quickly extinguish open fires.

Description

technical field [0001] The invention relates to the technical field of battery boxes, in particular to a battery box body with an automatic heat dissipation function. Background technique [0002] With the development of electric vehicles, the requirements for the charging and discharging rate of electric vehicle batteries are getting higher and higher. The higher the charging and discharging rate of electric vehicle batteries, the more heat is released by the battery. to the outside of the battery to ensure the normal and safe operation of the battery. [0003] However, at present, there are many cases of battery explosions caused by battery pack failures in electric vehicles, and even self-ignition of electric vehicles, which brings great economic losses to the owners; and the battery failures in electric vehicles are mostly at the connections between the battery packs. The upper and lower end faces of the battery pack are the connection points. If there is a small open f...

Problems solved by technology

[0003] However, at present, there are many cases of electric vehicles exploding due to battery pack failures, and even electric vehicles spontaneously ignite, causing large economic losses to car owners; and battery failures in electric vehicles are mostly caused by the connection between battery packs. On the upper and lower ends of the battery pack, here is the connection point. If there is a small open flame in the battery pack, it will be extinguished, which can not only ensure the safety of the car owner, but also reduce the loss of the car owner.
