Stepless energy regulation method for radar equipment cooling devices

Abstract

The invention relates to a stepless energy regulation method for radar equipment cooling devices. The method comprises the following steps of: when the temperature of the cooling liquid which radar electronic equipment needs is increased, detecting the temperature of the cooling liquid in a cooling heat exchanging system by using a temperature sensor and controlling a proportional electric hot-gas bypass valve to be properly opened by using a PID (Proportion Integration Differentiation) temperature controller to ensure that part condensing agent after being compressed by a fully-closed compressor is not condensed by an air-cooled condenser and directly delivered to a condenser inlet of a plate heat exchanger by utilizing the proportional electric hot-gas bypass valve, so that the condensing effect of the condensing agent in the plate heat exchanger is reduced and the temperature of the cooling liquid in the plate heat exchanger is increased; and conversely, continuously closing the proportional electric hot-gas bypass valve so as to reduce the temperature of the cooling liquid in the plate heat exchanger and satisfy the requirements of the radar electronic equipment on the temperature of the cooling liquid.

Description

technical field [0001] The invention relates to a stepless energy adjustment method of a radar equipment cooling device suitable for radar electronic equipment used in peacetime and wartime. Background technique [0002] Radar electronic equipment must be equipped with a cooling device to provide cooling fluid that meets the temperature, flow, and pressure requirements for the radar electronic thermal load. When the radar electronic equipment is in a low-temperature environment or not working at full load, the continuous operation of the compressor will easily cause the temperature of the liquid supply to be too low, which cannot meet the set temperature requirements, and cannot guarantee the normal operation of the radar electronic equipment. Most of the cooling devices for traditional radar electronic equipment The intermittent energy adjustment method is adopted, and the compressor is started and stopped to adjust the energy. The frequent start and stop of the compressor ...

Problems solved by technology

When the radar electronic equipment is in a low-temperature environment or not working at full load, the continuous operation of the compressor will easily cause the temperature of the liquid supply to be too low, which cannot meet the set temperature requirements, and cannot guarantee the normal operation of the radar electronic equipment. Most of the cooling devices for traditional radar electronic equipment The intermittent energy adjustment method is adopted, and the energy is adjusted by starting and stopping the compressor. The frequent start and stop of the compressor for a long time will greatly shorten the life of the compressor, and the temperature of the liquid supply fluctuates greatly, which cannot meet the requirements of electronic equipment. The temperature accuracy has a great influence on the normal use and service life of radar electronic equipment
