Heat radiation pipe sleeve structure for automobile battery

Abstract

The invention discloses a heat radiation pipe sleeve structure for an automobile battery. The heat radiation pipe sleeve structure comprises a reinforcing sleeve, a heat conducting sleeve structure and a heat absorption sleeve, wherein the heat conducting sleeve structure is coaxially fixed inside the reinforcing sleeve; the heat absorption sleeve is coaxially fixed inside a heat conducting sleeve; the heat conducting sleeve structure comprises the heat conducting sleeve, heat conducting fins and heat radiation fins; the heat conducting fins are fixed on the outer circumferential surface of the heat conducting sleeve are arranged along the length direction of the heat conducting sleeve; the heat conducting pins partially penetrate through the reinforcing sleeve and extend to the outside ofthe reinforcing sleeve; the heat radiation fins are fixed on the heat conducting pins positioned outside the reinforcing sleeve; the heat absorption sleeve is made of a composite phase change material; the heat conducting sleeve is made of heat conducting materials; the reinforcing sleeve is made of rigid plastics. The heat radiation pipe sleeve structure solves the problems that in the prior art, the heat radiation study of a power battery is mainly concentrated on a case structure of a battery module; the heat radiation problem of a power battery connecting circuit is ignored; when the temperature of the battery inside the module is raised, the temperature of a connecting circuit is influenced to be raised, so that an ordinary wrapping material can easily generate aging and cracking problems.

Description

technical field [0001] The invention relates to an automobile battery accessory, in particular to a heat dissipation pipe sleeve structure for an automobile battery. Background technique [0002] With the rapid and vigorous development of the economy, global energy shortages and environmental pollution have become increasingly prominent, energy conservation and emission reduction are gradually attracting the attention of the world, and the development of electric vehicles has also become a major trend. , especially when starting to climb a slope or suddenly accelerating, the discharge current increases instantaneously, thereby generating a large amount of heat, which can make the battery temperature inside the module reach 100°C, and it will be close to 200°C in the case of overcharging. At present, the heat dissipation research of the power battery mainly focuses on the shell structure of the battery module, but ignores the heat dissipation problem of the connection line of...

Problems solved by technology

[0003] The purpose of the present invention is to provide a heat dissipation pipe sleeve structure for automobile batteries, which solves the problem that the heat dissipation research of the power battery is mainly concentrated on the shell structure of the battery module, but ignores the heat dissipation problem of the connection line of the power battery. The rise of the internal battery temperature will inevitably affect the rise of the temperature of its connecting lines, making ordinary wrapping materials prone to aging and cracking problems
