Abstract
The invention discloses a liquid cooling grouping box of a power battery. The liquid cooling grouping box is characterized by comprising a box body, a general water inlet / outlet module arranged on a side wall of the box body and a plurality of groups of battery modules fixed in the box body; cuboid-shaped single batteries are arrayed vertically to form battery arrays; each battery module is composed of two battery arrays which are arranged in parallel and a liquid cooling heat exchange thin plate is vertically arranged between the two arrays of single batteries; a liquid flow channel is arranged in a body inner cavity of the liquid cooling heat exchange thin plate; a water inlet connector and a water outlet connector are communicated with the liquid flow channel. The liquid cooling grouping box of the power battery is applicable to a cuboid-shaped lithium ion battery or a soft package polymer battery, and efficient and uniform cooling and heat dissipation, and temperature rising and heating of the power battery can be realized; energy density of the box body of the power battery is greatly improved.
Description
technical field [0001] The invention relates to the technical field of group structure design of electric vehicle power batteries, in particular to a liquid-cooled group box body and a liquid-cooled heat exchange sheet for a pure electric vehicle or a hybrid vehicle. Background technique [0002] The technical key of electric vehicles is the power battery. The performance of the power battery directly determines the performance, safety and service life of the electric vehicle. Among the performance parameters of the power battery, the temperature is a key parameter that affects the safety, performance and life of the battery. If it is too low, it will lead to a decrease in the performance of the vehicle, and if it is too high, it may cause a safety accident. [0003] In a high-temperature environment, especially in the hot summer, the power battery will release a lot of heat during charging and discharging and when it is used in a high-temperature environment, and the heat w...
