Embodiment 1

[0029] This example is a power and cooling system based on supercritical carbon dioxide, which includes supercritical carbon dioxide source 1, booster pump 2, motor 7, module control valve 3, reversing valve 4, double-acting hydraulic cylinder 5 and radar front end6.

[0030] In this embodiment, there are two working modes, a power mode and a cooling mode, during operation, and the two working modes will be introduced respectively below.

[0031] Power mode: such as figure 1 As shown, PA in the module control valve 3 is connected but PB is not connected, the motor 7 drives the booster pump 2 to rotate, and supplies supercritical carbon dioxide to the reversing valve 4. When PA is connected to the reversing valve 4 and BT is connected, the supercritical The carbon dioxide pushes the double-acting hydraulic cylinder 5 out, and the supercritical carbon dioxide flows from the B port of the double-acting hydraulic cylinder 5 to the T port of the reversing valve 4, and then returns...

Abstract

The invention relates to a power and cooling system and method based on supercritical fluid, the system is composed of a supercritical carbon dioxide source, a booster pump, a motor, a module control valve, a reversing valve, a double-acting hydraulic cylinder and a radar front end which are tightly connected in sequence, and a working medium flowing among all parts in the system is supercritical carbon dioxide. The system has two working modes including a power mode and a cooling mode, when the system works in the power mode, the module control valve is communicated with the reversing valve, supercritical carbon dioxide enters the double-acting hydraulic cylinder to push the double-acting hydraulic cylinder to stretch out or retract, and the front end of the radar is erected or retracted. In the cooling mode, the module control valve is communicated with the front end of the radar, and supercritical carbon dioxide enters the front end of the radar to achieve cooling. According to the system, supercritical carbon dioxide serves as a medium, a hydraulic lifting system and a liquid cooling system are integrated, the structure is simple, and the maneuvering performance of the elevated maneuvering radar is improved.

Description

technical field [0001] The invention relates to a power and cooling system based on supercritical fluid, in particular, a power and cooling system based on supercritical carbon dioxide and suitable for overhead mobile radar. Background technique [0002] Elevated mobile radar has developed rapidly due to its strong maneuverability and good low-altitude performance. However, the increasing thermal power consumption and front-end quality have become the key factors restricting the further development of elevated mobile radar. At this stage, when the overhead mobile radar is working, the front end is erected to a certain height through the hydraulic lifting system, and the front end is cooled by air cooling or liquid cooling; Conducive to the improvement of radar maneuverability. [0003] At this stage, the published invention patents have carried out sufficient research on the liquid cooling system and the hydraulic lifting system respectively, but due to the limitation of th...
