New energy automobile power battery cooling plate

Abstract

The invention provides a new energy automobile power battery cooling plate, which comprises a lower plate sheet, an upper plate sheet, an inlet water pipe, an outlet water pipe and a convex hull structure, wherein the upper plate sheet is covered on the lower plate sheet, and an inlet flow channel and an outlet flow channel are formed between the lower plate sheet and the upper plate sheet; the inlet water pipe and the outlet water pipe are respectively connected with the upper plate sheet, and the inlet water pipe and the outlet water pipe are respectively communicated with the inlet flow channel and the outlet flow channel; and the convex hull structure is arranged on the side, which faces towards the upper plate sheet, of the lower plate sheet. Compared with the prior art, the invention has the following beneficial effects: the surface temperature of the cooling plate is enabled to be uniform in distribution, the heat accumulated on the surface of the power battery is effectively dissipated, the power battery is guaranteed to normally operate at the reasonable working temperature, the flow channel is simple in structure at the same time, the resistance loss of cooling media in flowing can be greatly reduced, the pump power requirement is reduced, and the cost of the new energy automobile is reduced. The new energy automobile power battery cooling plate is conducive to being widely applied in production and has great production practice significance.

Description

Technical field [0001] The present invention relates to the technical field of batteries, in particular to a new energy vehicle power battery cooling plate. Background technique [0002] With the increasing consumption of non-renewable energy and the increasingly severe environmental pollution, new energy vehicles are gradually replacing traditional fuel vehicles as a new trend in the development of the automotive industry. Power battery is the main energy source for driving new energy vehicles, and the stability of its performance will directly affect the performance of the entire new energy vehicle and the safety and reliability of the vehicle. [0003] In order to increase the cruising range of new energy vehicles and complete the operating conditions of new energy vehicles such as acceleration, emergency stopping and climbing, it is easy to cause the operating temperature of the battery to rise. When the battery temperature gradually rises and the heat cannot be released in ti...

Problems solved by technology

[0005] But at present, for the cooling plate used for cooling the power battery, the flow channel for the cooling medium to flow is mostly S-shaped, which makes the temperature distribution on the surface of the cooling plate uneven, and then makes the temperature between the multiple power battery cores that need to be cooled The distribution is not uniform, and the S-shaped flow channel leads to a high pressure drop of the cooling medium, and the performance requirements of the water pump are relatively high, which brings about an increase in the cost of new energy vehicles
