TEC (Thermo Electric Cooler) temperature control module for power battery pack and use method thereof

Abstract

The invention discloses a TEC (Thermo Electric Cooler) temperature control module for a power battery pack. The TEC temperature control module comprises a semiconductor chilling plate and a fastener,wherein the semiconductor chilling plate has a hot end face and a cold end face; the hot end face is in close contact with the substrate surface of a radiator, and coated with a heat conducting medium; the cold end face is in close contact with the substrate surface of a cold guide substrate, and coated with a heat conducting medium; heat insulating cotton is arranged between the cold guide substrate and the cold end face; the surface of the cold guide substrate is provided with a soft heat conducting pad; the fastener is used for fastening the radiator and the cold guide substrate; and the semiconductor chilling plate is arranged between the radiator and the cold guide substrate. Through adoption of the TEC temperature control module, heat management of batteries in the power battery packin different application environments is realized; high-temperature refrigeration and low-temperature heating of the batteries can be realized at the same time through TEC polarity reversal; and theservice lives of the batteries are ensured effectively. A pure solid-state structure is adopted, so that leakage risk is prevented, and the security of the battery pack is enhanced effectively.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a TEC temperature control module for a power battery pack and a method for using the same. Background technique [0002] In response to the national call for "energy saving and emission reduction", new energy vehicles have been widely promoted and applied as a solution to energy and environmental problems. As the core component of new energy vehicles, the power battery plays the role of the "heart" of the entire system. Its thermal management can be said to be an important part of the vehicle power battery system, which can increase battery life, improve battery performance and ensure battery safety. effect. [0003] At present, the mainstream thermal management of power batteries mainly adopts the active cooling method. Active cooling refers to the consumption of a certain amount of extra work to transfer heat from one end to the other. The current solutions mai...
