High-pressure cooling air system for electronic machine cabinet

Abstract

The invention provides a high pressure wind cooling system used for an electronic cabinet. The high pressure wind cooling system comprises a wind pipe system, a high pressure wind cabinet, a refrigerant water system, a centralization type cold water machine unit, a cooling water system and a control system. The centralization type cold water machine unit and the high pressure wind cabinet are connected into a whole through the refrigerant water system, to form refrigerant water circulation; the high pressure wind cabinet and an electronic cabinet are connected into a whole through the wind pipe system, to form cooling air circulation; the heat of the electronic cabinet is brought to the high pressure wind cabinet through circulated air, and is conducted to the refrigerant water system by a fin type heat exchanger, and is then conducted to the cooling water system through the cold water machine unit. The high pressure wind cooling system adopts the control mode combining a PLC with thecontrol of a relay and automatically runs according to the settings, the autoimmunization degree is high, the running is stable, and the labor intensity is reduced. In order to enhance the reliability of the system, an air conditioning refrigerant water system is externally connected aside the refrigerant water system, an air conditioning cooling water system is externally connected aside the cooling water system, so that the normal operation of the system is guaranteed, and the uninterrupted stable operation of the electronic cabinet is realized.

Description

technical field [0001] The invention relates to a high-pressure cooling air system for an electronic cabinet. Background technique [0002] At present, most of the electronic cabinets are open cabinets. There is no cooling and dehumidification measures inside, and only local ventilation and heat dissipation are used. Working in a long-term harsh environment, the corrosion of unfavorable factors such as salt spray, mold, moisture, and dust often leads to The working state of the electronic components deviates, and even causes damage to the electronic components, which affects the reliability of the working system; in some closed cabinets, due to the heat not being dissipated in time, the temperature of the electronic components rises sharply, the work is unstable, and the life of the components is greatly reduced. The increased probability of failure also affects the stability and reliability of the system. The original supporting cooling equipment is the central air-conditi...

[0002] At present, most of the electronic cabinets are open cabinets. There is no cooling and dehumidification measures inside, and only local ventilation and heat dissipation are used. Working in a long-term harsh environment, the corrosion of unfavorable factors such as salt spray, mold, moisture, and dust often leads to The working state of the electronic components deviates, and even causes damage to the electronic components, which affects the reliability of the working system; in some closed cabinets, due to the heat not being dissipated in time, the temperature of the electronic components rises sharply, the work is unstable, and the life of the components is greatly reduced. The probability of failure increases, which also affects the stability and reliability of the system

The original supporting cooling equipment is the central air-conditioning terminal unit, the air volume is small, the pressure is not enough, the air quality only adopts the method of primary filter, and the salt mist, dust, and moisture are not purified, which cannot meet the needs of the electronic cabinet.
