Abstract

The invention relates to a motor temperature control device used in an infrared band test system, which belongs to the field of aerospace technology. Heat insulation component, the motor temperature control device quickly guides the heat generated by the motor to the cold end through the heat conduction cable installation bracket and heat conduction cable, and uses the temperature measurement circuit and the heating circuit formed by the thermal controller and the temperature measurement sensor and the heating plate respectively Realize active temperature control when the motor is not working. At the same time, use multi-layer heat insulation components to cover the heat conduction cable mounting bracket, heat conduction cable, temperature measurement sensor and heating sheet, so that the motor can be actively controlled whether it is in the working state or in active temperature control. In this state, the heat radiated from the motor to the space is greatly reduced, so that no background noise will be generated to the infrared band test system, which is conducive to ensuring the measurement accuracy and accuracy of the infrared band test system.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a motor temperature control device for an infrared band test system. Background technique [0002] Under the background of vacuum and low temperature (if in space, the background temperature is 4K; if the vacuum tank with liquid nitrogen circuit is used, the background temperature is about 100K), the motor will generate a lot of heat accumulation when it works, causing the motor temperature to rise rapidly or even exceed the working temperature range , so it is necessary to adopt necessary heat dissipation measures to dissipate heat from the motor. The commonly used and effective heat dissipation method is to expose a part of the outer surface of the motor and spray a high-emissivity coating, and use radiation heat dissipation to dissipate the heat to the cold and dark space. Install a heat radiator to increase the radiation and heat dissipation area of ​​the motor, enhance t...
