Heat-rejecting Unit

A heat-rejecting unit is a device used in spacecraft to dissipate excess heat generated by the spacecraft's systems and components. The unit typically consists of a radiator, a heat exchanger, and a pump or other mechanism to circulate a coolant fluid through the system. The radiator is designed to radiate the heat away from the spacecraft, while the heat exchanger transfers the heat from the spacecraft's coolant fluid to the radiator. The pump or other mechanism circulates the coolant fluid through the system, ensuring that the excess heat is efficiently transferred and dissipated. The heat-rejecting unit is a critical component of spacecraft thermal management systems, which are essential for maintaining the proper operating temperature of the spacecraft's systems and components.
