Abstract

The invention discloses a temperature control device of a storage battery for a spacecraft. The temperature control device provided by the invention comprises a temperature control plate [2]. Storage battery structure blocks [1] are installed at an inner side of the temperature control plate [2]. Transverse heating pipes are pre-embedded in a side which belongs to the temperature control plate [2] and is close to a storage battery installation surface. Vertical heating pipes [6] are pre-embedded in parts close to the storage battery installation surface. A hot expanding plate [3] is arranged at a part close to the storage battery installation surface. The hot expanding plate [3] transversely extends out of a heat dissipation plate [4]. Sides of the storage battery structure blocks [1] are provided with heating devices. The temperature control device provided by the invention solves the problem of temperature control of a high-calorific value storage battery used for a spacecraft, and has good temperature control effects, high reliability and a flexible design.

Description

technical field [0001] The invention relates to a temperature control device for a storage battery with high calorific value used in a space vehicle. Background technique [0002] As an important part of the aircraft power system, the space battery is the only power supply equipment during the phases of the aircraft entering orbit and operating in the shadow period. Batteries are sensitive to temperature. Too high or too low temperature will affect the performance and life of the battery: if the temperature is too low, the effective charge capacity of the battery cannot be guaranteed; if the temperature is too high, the charging efficiency will decrease, and the heat consumption of the battery will decrease can cause thermal runaway. Therefore, battery thermal control is crucial to the reliability of the battery and even the aircraft. [0003] The battery generates a lot of heat, which is generally more than 15% of the output power of the aircraft. Taking the current mains...
