Large power supply unit heat regulation and control device and regulation and control method

Abstract

The invention provides a large power supply unit heat regulation and control device and method, and the device comprises a refrigeration box, a gas-liquid compressor and a plurality of liquid-gas converters, and the refrigeration box is used for being arranged at the bottom of an electrical box; the gas-liquid compressor is arranged in the refrigeration box, and the outlet end of the gas-liquid compressor is connected with a first pipeline; the liquid-gas conversion machines are connected to the outlet end of the first pipeline in parallel, the outlet ends of the liquid-gas conversion machines are connected with a second pipeline, and the outlet end of the second pipeline is connected with the gas-liquid compressor. According to the heat regulation and control device of the large power supply unit, the gas-liquid compressor is used for compressing air from a gas state to a liquid state, the liquid gas is conveyed into the liquid-gas converter through the first pipeline to be converted into gaseous gas, heat energy in the electrical box is absorbed in the process of converting the liquid gas into the gaseous gas, and the heat energy in the electrical box is recovered. The temperature in the electrical cabinet is effectively reduced, and normal operation of equipment in the electrical cabinet is ensured.

Description

technical field [0001] The invention belongs to the technical field of large-scale power supply heat regulation, and more particularly relates to a large-scale power supply unit heat regulation device and regulation method. Background technique [0002] With the development of science and technology, the supply capacity of the power supply system has also been greatly improved. In the construction of large-scale power grids, in order to save space and facilitate management and maintenance, many chips and electronic components are integrated on the same circuit board in the electrical box. Because the power consumption of the above-mentioned power supply equipment is very large and requires long-term non-stop work, Therefore, a large amount of heat energy will be emitted during the use of the electrical box, and a large amount of static electricity will also be generated. [0003] In actual use, the equipment generally dissipates heat by opening the cabinet door in order to ...

Problems solved by technology

[0003] In actual use, the equipment generally cools down by opening the cabinet door to dissipate heat. However, the above method easily causes the static electricity inside the equipment to absorb dust particles in the air, further reducing the heat dissipation performance of the equipment. paralysis
