Problems solved by technology

The disadvantage is that due to the low thermal conductivity of the air and the weak flow of natural convection, the heat dissipation efficiency of natural cooling is generally low
Although the patent improves the heat dissipation effect through the design of flow sharing, it cannot improve the problem of uneven cooling effect

Abstract

The invention relates to a liquid cooling apparatus, and especially relates to a battery pack bidirectional cooling device. The battery pack bidirectional cooling device comprises a forward cooling pipe housing, a reverse cooling pipe, a forward liquid coolant, a reverse liquid coolant, a condenser tube and several electrical cores, and the forward cooling pipe housing comprises a lower housing, an upper housing, a cooling tank and an evaporation groove. The device realizes whole-course equalized cooling on a battery pack, and installation of the device is simple.

Description

technical field [0001] The invention relates to a liquid cooling device, in particular to a bidirectional cooling device for a battery pack. Background technique [0002] The design of the battery pack needs to ensure that the battery is always in a relatively comfortable temperature environment (battery temperature range: 15~40°C; temperature difference between batteries: 5~10°C), so as to ensure the long life of the vehicle and good cruising range , good power performance and short charging time. [0003] The commonly used cooling systems for battery packs are mainly divided into four types: natural cooling system, air cooling system, liquid cooling system and direct cooling system. [0004] The natural cooling system uses the natural convection heat exchange of the air to transfer the heat of the battery pack, module and battery cells to the surrounding air, thereby reducing the temperature of the battery cells to a certain extent. The disadvantage is that due to the lo...
