Liquid cooling plate and liquid cooling device

Abstract

The invention discloses a liquid cooling plate, which comprises an upper-layer plate, a lower-layer plate and a middle plate connected between the upper-layer plate and the lower-layer plate, whereina mounting groove is formed in one side, close to the middle plate, of the upper-layer plate, a water inlet pipe and a water outlet pipe communicated with the mounting groove are arranged on one side,deviating from the middle plate, of the upper-layer plate, the middle of the middle plate is stamped to form a plurality of protruding strips and a plurality of liquid cooling grooves opposite to theprotruding strips and in one-to-one correspondence with the protruding strips, each protruding strip is located in the mounting groove and connected with the bottom of the mounting groove, and the two sides of each protruding strip are each provided with a liquid cooling hole for communicating the corresponding liquid cooling groove with the mounting groove. The invention further provides a liquid cooling device comprising the liquid cooling plate. According to the invention, the protruding strips of the middle plate and the liquid cooling grooves are sealed in the mounting groove of the upper-layer plate through the lower-layer plate, and the liquid cooling holes are formed in the protruding strips to form the heat dissipation channel, so that a pipeline for a cooling liquid to circulatedoes not need to be mounted on the liquid cooling plate, the structure is simple and reliable, submission is small, and production and manufacturing are facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of heat management equipment, in particular to a liquid cooling plate and a liquid cooling device. 【Background technique】 [0002] With the continuous consumption of non-renewable resources and the increasingly prominent environmental problems, lithium-ion batteries have developed rapidly in recent years. At present, multiple lithium-ion batteries are usually used as a battery module. However, lithium-ion batteries are secondary batteries that generate a lot of heat during use. Therefore, in order to avoid thermal runaway of lithium-ion batteries, battery modules are usually equipped with In the prior art, the application of liquid cooling in battery modules has become a trend due to its high heat dissipation efficiency. However, the pipeline design of the liquid cooling device is relatively complicated and the volume is relatively large. Huge, affecting the performance of the battery module. [0003] In...
