Problems solved by technology

However, the fan requires extra power to drive, which is usually directly provided by the battery module, which increases the burden on the battery module
In addition, due to the space required for the forced airflow generated by the fan to flow smoothly and the installation space of the fan (or heat dissipation fins), the overall battery module (including the battery module body, fan) using this solution and heat dissipation fins) will increase significantly, which is not conducive to the setting of battery modules

Abstract

The invention provides a battery module, which includes a casing, a first battery pack, a first heat conduction part, a second battery pack and a second heat conduction part. The housing includes a first housing part, a second housing part opposite to the first housing part, and two connecting parts connecting the first housing part and the second housing part, the first housing part has a first channel side The wall and the first accommodating space, the second housing part has a second channel side wall and the second accommodating space, the first channel side wall is opposite to the second channel side wall and forms a through channel, and the first housing part , the second casing part, and the two connecting parts surround the through passage to form an annular structure, and the through passage extends up and down in the annular structure. The first battery pack is arranged in the first accommodating space. The first heat conducting member is disposed in the first accommodating space and contacts the first battery pack and the side wall of the first channel. The second battery pack is arranged in the second accommodating space. The second heat conduction member is disposed in the second accommodating space and contacts the second battery pack and the side wall of the second channel.

Description

technical field [0001] The invention relates to a battery module, in particular to a passive heat dissipation battery module. Background technique [0002] A battery is a device that uses chemical reactions to convert chemical energy into electrical energy. The battery module contains multiple batteries, so it can provide greater current and longer usage time than a single battery. However, in principle, the battery generates heat during operation, which increases the temperature of the battery, which is not conducive to the discharge efficiency. In order to reduce the volume of the battery module, the batteries packaged in the battery module are usually arranged closely, but this arrangement usually makes it more difficult to dissipate the heat generated by the batteries, so that the temperature of the batteries remains high. In order to prevent the temperature of the battery module from being too high during operation, heat dissipation fins are usually used on the entire...
