Description
Technical field
The utility model relates to a kind of electronic device cooling apparatus, be specifically a kind of be applicable to radar electric equipment at ordinary times with the stepless energy adjustment refrigerating system of using wartime.
Background technology
Radar electric equipment must be equipped with cooling device and be used to the radar electric heat load that the cooling fluid of satisfied temperature, flow, pressure requirement is provided.When radar electric equipment is in low temperature environment or non-operation at full load, the compressor continuous firing easily causes for liquid temp excessively low, do not reach and set temperature requirement, can not guarantee the normal operation of radar electric equipment, the most batch (-type) energy adjustment modes that adopt of tradition radar electric apparatus cools device, adopt the mode of start/stop of compressor to come adjusting energy, the long-term frequent start-stop of compressor, this will shorten the compressor life-span greatly, and its feed flow temperature fluctuation is larger, do not reach the desired temperature accuracy of electronic equipment, larger on the normal use of radar electric equipment and impact in useful life.
Summary of the invention
In order to solve above-mentioned deficiency in the prior art, it is a kind of simple in structure, compact that the utility model provides, can satisfy radar electric equipment and under worst cold case or low load behavior, cool off requirement, the cooling precision is high, is conducive to prolong the stepless energy adjustment refrigerating system of compressor and radar electric service life of equipment.
The technical solution adopted in the utility model is: a kind of stepless energy adjustment refrigerating system, it is characterized in that: comprise totally-enclosed compressor, air-cooled condenser with condensation fan, reservoir, device for drying and filtering, heating power expansion valve, plate heat exchanger, the electronic hot gas bypass valve of proportional regulation type and PID temperature controller, the totally-enclosed compressor exhaust outlet is successively through air-cooled condenser, reservoir, device for drying and filtering, heating power expansion valve is connected to plate heat exchanger condensing agent entrance, the outlet of plate heat exchanger condensing agent connects the totally-enclosed compressor air inlet, between totally-enclosed compressor exhaust outlet and the plate heat exchanger condensing agent entrance bypass line is set, bypass line is provided with the electronic hot gas bypass valve of proportional regulation type, and the electronic hot gas bypass valve of described proportional regulation type is connected the PID temperature controller with heating power expansion valve.
Temperature-sensitive bag and the balance pipe of described heating power expansion valve all are connected to the totally-enclosed compressor air inlet.
During refrigerating system work, totally-enclosed compressor is sent condensing agent into air-cooled condenser, undertaken air-cooled by condensation fan, condensing agent is delivered to plate heat exchanger condensing agent entrance through reservoir, device for drying and filtering, heating power expansion valve, sends the condensing agent after the heat exchange back to totally-enclosed compressor by the outlet of plate heat exchanger condensing agent at last; In the whole working, because the required coolant temperature of radar electric equipment changes with the variation of environment for use and life cycle, refrigerating system changes synchronously to the condensing agent demand that plate heat exchanger provides, when the required coolant temperature of radar electric equipment improves, opened in right amount by the electronic hot gas bypass valve of PID temperature controller control ratio type, by the part of the condensing agent after the totally-enclosed compressor compression without the air-cooled condenser condensation, directly delivered to the freezing machine entrance of plate heat exchanger by the electronic hot gas bypass valve of proportional-type, effectively reduce condensing agent condensation effect in the plate heat exchanger, improved the temperature of cooling fluid in the plate heat exchanger; Otherwise, then constantly close the electronic hot gas bypass valve of proportional-type, with the temperature of cooling fluid in the reduction plate heat exchanger, thereby satisfy radar electric equipment to the requirement of coolant temperature.Simultaneously, the condensing agent temperature of sending totally-enclosed compressor back to is surveyed in the temperature-sensitive detective of heating power expansion valve, when sending the condensing agent excess Temperature of totally-enclosed compressor back to, open size by PID temperature controller control heating power expansion valve, regulate gradually the condensing agent flow of being delivered to plate heat exchanger by air-cooled condenser, further the heat exchange cooling of plate heat exchanger is regulated and control; Cooperate the balance pipe of heating power expansion valve to be connected to the totally-enclosed compressor air inlet, condensing agent pressure in the pipeline is regulated, when guaranteeing that the electronic hot gas bypass valve of proportional-type and heating power expansion valve are opened variation, refrigerating system internal pressure balance is conducive to improve system safety.
The electronic hot gas bypass valve of the utility model adoption rate type and heating power expansion valve are realized the pressure of condensing agent in the refrigerating system, the stepless energy adjustment of flow, thereby guarantee the reliable and stable work of radar electric equipment, this system cools degree of regulation is high, the energy adjustment scope is large, stable, can take into account the environmental requirement under worst hot case and the worst cold case, satisfy the cooling in wartime of radar electric equipment, applicability is strong.
