Abstract

The invention discloses a lithium battery power assembly cooling system, which is used for solving the problem of a temperature rise of an existing battery pack. The lithium battery power assembly cooling system comprises a lithium battery pack, a liquid pump, a radiator and a liquid transfer pipe, wherein the lithium battery pack comprises battery cells, average-temperature assemblies and a shell; the battery cells and the average-temperature assemblies are mutually laminated at intervals; each average-temperature assembly comprises a left shell, a right shell, a liquid guide sheet, a liquid inlet pipe and liquid outlet pipes; each left shell and the corresponding right shell are of a symmetrical structure; an internal chamber of each liquid guide sheet is a cooling liquid channel; the edge of each liquid guide sheet is embedded into a joint between the corresponding left shell and right shell; average-temperature fields are formed between two sides of each liquid guide sheet and the corresponding left shell and right shell respectively; a center hole and spiral liquid distribution slots are arranged in two side surfaces of each liquid guide sheet; and the shell is connected with each liquid guide sheet through four liquid outlet pipes and one liquid inlet pipe to form a cooling medium flow channel. According to the lithium battery power assembly cooling system, the flow rate of a cooling medium in each average-temperature assembly can be controlled to achieve the target of controlling the internal temperature of each battery cell.

Description

technical field [0001] The invention relates to the technical field of new energy lithium-electric powertrain heat dissipation system, specifically a lithium-electric powertrain heat dissipation system with better temperature control effect. Background technique [0002] Lithium batteries are the core components of electric vehicles, and their performance directly affects the performance of electric vehicles. Lithium batteries are generally large in size and occupy the position of the chassis of the vehicle, and their heat dissipation effect is very poor. [0003] Today's batteries are generally cooled by natural cooling, air cooling or water cooling. Take lithium batteries as an example. Battery life and charging and discharging effects. [0004] Among them, the three heat dissipation methods have their own advantages. Natural cooling is gradually eliminated due to its low cooling efficiency. Air cooling has a simple structure and is the mainstream in the current market. W...
