Problems solved by technology

At present, the heat sink used for cooling is mainly ram air, adding bleed air from the outer surface of the aircraft to introduce ram air usually affects the aerodynamic shape of the aircraft, increases the resistance of the aircraft, causes large compensatory losses, and reduces the overall performance of the aircraft (aircraft range, flight time, etc.) and operating economics

Embodiment Construction

[0022] An equipment cooling system includes a coolant booster pump 1, a heat exchanger 2, a fuel booster pump 5, a fuel tank 6, and equipment to be cooled 10.

[0023] The coolant booster pump 1, the heat exchanger 2, and the equipment to be cooled 10 are connected through pipelines. The coolant booster pump 1 drives the coolant to flow in the pipeline. The fuel oil performs heat exchange, and the cooled coolant flows through the equipment to be cooled 10 to take away the heat generated when the equipment to be cooled 10 works, forming a working cycle. The fuel booster pump 5 sucks the fuel in the fuel tank 6, and exchanges heat with the relatively higher temperature coolant when it flows through the heat exchanger 2. Part of the fuel after the temperature rise is sent to the engine combustion chamber for combustion, and the other part Send back fuel tank 6, carry out heat exchange with the atmosphere of outside by fuel tank wall plate.

Abstract

The invention belongs to the technical field of aviation and relates to an equipment cooling system. The equipment cooling system comprises a cooling liquid booster pump, a heat exchanger, to-be-cooled equipment, a temperature sensor, a pressure sensor, a flow meter, a liquid storage / buffer container, a display control device and the like. Electronic equipment is cooled by using fuel oil; meanwhile, the heating value of the electronic equipment and the heating value generated by the system are recycled through an engine, energy on the aircraft is effectively utilized, the deep management of the energy is achieved, the defect that a cooling system with ram air as a heat sink is high in compensation loss is overcome, and the use cost of the system can be reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the field of aviation technology and relates to an equipment cooling system. Background technique [0002] The electronic equipment cooling system is used to ensure the working environment of aircraft electronic equipment. Its main function is to cool electronic equipment and ensure the safe and efficient work of electronic equipment. The system consists of booster pump, heat exchanger, equipment to be cooled, temperature sensor, pressure sensor, flow meter, liquid storage / buffer container and display control device. At present, the cooling system for high-power electronic equipment with high heating power and high heat flux density uses low-freezing-point coolant as the working medium. During the cooling process, the heat generated by the electronic equipment is transferred to the coolant through the cold plate. The coolant is carried away, and finally carried away through other heat sinks and discharged to the external envir...
