Micro-channel battery thermal management device

Abstract

The invention discloses a micro-channel battery thermal management device. The micro-channel battery thermal management device comprises a box, batteries, semiconductor refrigeration chips, a heat exchange device and a control device; the plurality of batteries are installed in the box, such that a multi-line structure is formed; a clearance exists every two lines of batteries; one end of the heat exchange device is inserted into the clearance and in contact with the batteries; the semiconductor refrigeration chips are fixedly installed on the heat exchange device; the output end of the control device is connected with the control input ends of the semiconductor refrigeration chips; the heat exchange device comprises an inlet collecting chamber, an outlet collecting chamber and a water pipe, wherein two ends of the water pipe are respectively communicated with the inlet collecting chamber and the outlet collecting chamber; the water inlet of the inlet collecting chamber communicate with the water outlet of the outlet collecting chamber through a water pump; and one end of the water pipe extends in the clearance and is in contact with the batteries. The micro-channel battery thermal management device disclosed by the invention has the beneficial effects of being automatically controlled, high in heat exchange efficiency, low in cost investment, steady and reliable.

Description

technical field [0001] The invention belongs to the technical field of battery heat management, in particular to a microchannel battery heat management device. Background technique [0002] With the development of the world economy, with the increase of energy demand and the enhancement of environmental protection awareness in various countries, many tools or equipment powered by oil use electricity as the driving energy. The secondary power rechargeable battery has a large discharge rate and Due to the large output power, it is increasingly used in energy storage systems and power supply systems. The charging and discharging of existing secondary batteries is completed by a series of complex chemical reaction processes. The violent chemical reactions in the charging and discharging process will be accompanied by a large amount of heat generated and accumulated inside the battery. In the case of high temperature, it is easy to lose the discharge performance, and even cause ...
