Abstract

The invention discloses a water-cooling heat dissipation device of a new energy automobile battery pack. The water-cooling heat dissipation device comprises a water inlet pipe, a water outlet pipe and a water-cooling plate, wherein the water inlet pipe is used for allowing cooling water to enter, the water outlet pipe is used for allowing the cooling water to flow out, the water-cooling plate is connected with the water inlet pipe and the water outlet pipe and is used for being in contact with a battery cell of the battery pack, a water inlet passage is arranged in the water inlet pipe, a water discharge passage is arranged in the water outlet pipe, and a cooling water channel is arranged in the water-cooling plate, communicates with the water inlet passage and the water discharge passage, is used for allowing the cooling water in the water inlet passage to enter the water discharge passage and is S-shaped. In the water-cooling heat dissipation device of the new energy automobile battery pack, the S-shaped cooling water channel is arranged in the water-cooling plate, heat transfer is more balanced, so that the heat dissipation efficiency is improved; and moreover, the water-cooling heat dissipation device is more compact in structure, lighter in weight and low in manufacturing cost.

Description

Technical field [0001] The invention belongs to the technical field of power lithium batteries. Specifically, the invention relates to a water-cooled heat dissipation device for a battery pack of a new energy automobile. Background technique [0002] Electric vehicles have the advantages of low noise, good driving stability, and zero emissions. They are of positive significance for maintaining national energy security, reducing exhaust emissions, promoting the development of the automobile industry, and ensuring the sustainable development of society. Electric vehicles use batteries as power output carriers, and battery temperature has a great impact on battery life. For system development aimed at increasing battery system output power and reducing the number of batteries, the cooling of single batteries is an important technology that takes into account both performance and life. It is imperative to develop a simple and efficient cooling system. [0003] The existing battery pac...
