Title:
COOLING DEVICE AND BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/179727
Kind Code:
A1
Abstract:
A cooling device and a battery pack, which relate to the technical field of batteries. The cooling device is used for cooling a battery module, and comprises a water inlet harmonica-shaped pipe, a water outlet harmonica-shaped pipe, an S-shaped pipeline assembly, and a conduit, wherein the S-shaped pipeline assembly comprises at least one harmonica-shaped pipe group, and each harmonica-shaped pipe group comprises two harmonica-shaped pipes; the water outlet harmonica-shaped pipe, the water inlet harmonica-shaped pipe, and the harmonica-shaped pipe group are sequentially arranged in parallel, the conduit is arranged in the direction of a connecting line between the water outlet harmonica-shaped pipe and the water inlet harmonica-shaped pipe, and the water inlet harmonica-shaped pipe, the S-shaped pipeline assembly, the conduit, and the water outlet harmonica-shaped pipe sequentially communicate with one another; and in the direction of the connecting line between the water outlet harmonica-shaped pipe and the water inlet harmonica-shaped pipe, the water outlet harmonica-shaped pipe and the water inlet harmonica-shaped pipe form a temperature equalizing unit, the two harmonica-shaped pipes of each harmonica-shaped pipe group form a temperature equalizing unit, and the temperature equalizing units are used for equalizing the temperatures of two opposite sides of a battery module. The cooling device can not only equalize the temperatures of two opposite sides of the same battery module, but can also reduce the temperature difference between different battery modules, thereby improving the consistency of the depths of discharge of different battery modules.
