Description

Technical Field

[0001] The utility model relates to the technical field of battery PACK, in particular to a battery liquid cooling pipe and a battery module. Background Technique

[0002] In the process of the development of lithium batteries, the thermal management system of the battery is crucial. A good thermal management system can keep the lithium battery reliable and stable for a long time under specific environmental conditions. The battery generates heat during the charging and discharging process. The heat of the battery cannot be taken away by natural cooling. The long-term accumulation of heat may cause the performance of the battery to decline and even increase the risk of battery thermal runaway. The heat transfer efficiency inside the battery is limited. This limited heat transfer efficiency will not only lead to the cooling speed of the battery, but also cause the performance of the battery to decrease and the service life to be reduced during long-term use, and even cause the battery to be damaged.

[0003] The prior art CN204375872U proposes a battery module cooling structure, including a battery bracket and a plurality of single cells arranged in the battery bracket. The battery bracket has an upper surface and a side surface. A plurality of heat dissipation through holes penetrating the battery bracket are evenly arranged on the upper surface. A plurality of heat dissipation pipes are evenly connected to the side surface. The hot ends of the heat dissipation pipes completely penetrate into the battery bracket. The heat dissipation through holes communicate with the heat dissipation pipes. The cooling ends of the heat dissipation pipes are placed outside the battery bracket. A cooling air duct is formed around the battery cells through the heat dissipation through holes. When the air in the heat dissipation pipes expands due to heat, the heat moves towards the cooling ends. At this time, the cold air around the upper surface enters through the heat dissipation through holes, thereby forming a rapid air flow and actively exchanging heat with the air efficiently to achieve a good heat dissipation effect. The problem of heat accumulation and temperature rise of the battery during use is solved, the service life of the battery is significantly extended, and its safety performance is ensured.

[0004] When the prior art is in use, in order to avoid damage caused by too high battery temperature, the air circulation or flow is usually accelerated to dissipate heat. However, when it is in use, the heat carried away by the air circulation is less, and the heat dissipation efficiency is low. Content of the Utility Model
