Problems solved by technology

[0006] It can be seen from the above that the installation problem of the secondary battery has seriously delayed the application of the secondary battery
At the same time, the secondary battery will generate heat during charging and discharging. If the battery temperature is too high, it will accelerate the high-temperature capacity decay rate, reduce the overall performance of the battery, and shorten the service life of the battery. Therefore, the heat dissipation problem of the secondary battery is also a delay. One of the factors for the application of secondary batteries

Abstract

The invention discloses a combined type easy heat emission metal capsule, providing a metal capsule with good heat dispersion, which can be used singlely and jointly, and the union, the installation and the fixed method between the metal capsules are simple, applied in a plurality of fields. The combined type easy heat emission metal capsule described in the invention adopts the metal materials with easy heat transmission, composed of a capsule body and a capsule cover, and the outside of the metal capsule is provided with a spread groove and a convex, and the inside is provided with a convex and/or an antislip strip. The combined type easy heat emission metal capsule of the invention can be applied in the field of the battery case and the DC-DC transducer case which have high requirement on the heat emission and the metal capsule requires assemblying.

Description

technical field [0001] The invention relates to a box, and more particularly to a metal box that can be freely combined and is easy to dissipate heat. Background technique [0002] With the increase in the amount of power that secondary batteries can provide, the range of applications is becoming wider and wider. For example, it can be applied to electric motorcycles, electric vehicles, and can be combined with solar cells to provide power. Although secondary batteries can be used in many fields, However, there are many problems when using it, such as: [0003] Electric motorcycles have been popularized as a new type of transportation tool, and the secondary batteries need to be charged after the electric motorcycles run for a certain distance. Since electric motorcycles are generally parked outdoors, there are usually no power sockets for charging, so when charging is required, people can only lead down a power socket from upstairs to charge the electric motorcycles parked...
