Water circulation heat exchange type lithium battery device for new-energy automobile

Abstract

The invention discloses a water circulation heat exchange type lithium battery device for a new-energy automobile. The water circulation heat exchange type lithium battery device comprises a bottom heat exchange connecting plate, a water tank, two lithium battery bodies and a bottom shell, wherein the bottom heat exchange connecting plate is fixed on a battery cabin bottom plate of the automobile, the water tank is fixed on the bottom heat exchange connecting plate, the bottom shell is located right above the water tank, and support legs are fixed at the bottom of the bottom shell and fixed on the top surface of the bottom heat exchange connecting plate; the lower portions of the two lithium battery bodies are inserted into the bottom shell, an upper shell is located above the bottom shell, the upper portions of the two lithium battery bodies are inserted into the upper shell, a middle support block is clamped between the two lithium battery bodies, a vertical circulation hole is formed in the middle of the middle support block, annular limit grooves are formed in the outer lateral walls of the lower portions of the two lithium battery bodies, and annular heat exchange rings are inserted into the annular limit grooves of the two lithium battery bodies. The water circulation heat exchange type lithium battery device has the advantages that the lithium battery device is good in cooling effect and radiates through water circulation and blowing so as to be longer in service life.

Description

[0001] Technical field: [0002] The invention relates to the technical field of new energy vehicle manufacturing, and more specifically relates to a water cycle heat exchange lithium battery device for new energy vehicles. [0003] Background technique: [0004] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0005] For example, electric vehicles, hybrid vehicles, etc. Among hybrid vehicles, some of them first use electric power as the starting power of the car, and then switch to fuel power, so as to prevent the initial start-up of the car from consuming fuel, causing waste due to insufficient fuel combustion and causing The problem of exhaust gas pollution, however, because the existi...
