Abstract

A heat radiation device used on power battery set is prepared as setting holes on bottom-layer heat collection plate and top-layer heat collection plate, arranging heat tubes in said holes and connecting heat tubes in holes on bottom-layer heat collection plate through to heat tubes in holes on top-layer heat collection plate. The power battery set applying said heat radiation device is also disclosed.

Description

technical field [0001] The present invention relates to a heat dissipation device, more particularly to a heat dissipation device for a power battery pack and a power battery pack using the heat dissipation device. Background technique [0002] At present, power battery packs are widely used in various fields, for example, they can be used in electric vehicles. With the enhancement of people's awareness of protecting the environment and saving energy, the development of electric vehicles has attracted widespread attention, and the power battery pack, which is the heart of electric vehicles, is the focus of electric vehicle research. [0003] The power battery pack is composed of several single cells connected in series or in parallel in different ways, and then clamped and fixed. The single battery can be a traditional alkaline secondary battery such as a nickel separator or nickel metal hydride, or a lithium ion battery. [0004] For example, CN 2450785Y discloses a squar...
