Abstract
The utility model provides a compression refrigeration system for a power distribution cabinet. A cabinet body and the compression refrigeration system are included in the utility model; a circulation air duct is arranged at a side of the cabinet body, an air outlet of the circulation air duct is arranged above the cabinet body, a return air inlet of the circulation air duct is arranged below the cabinet body, and the air outlet and the return air inlet of the circulation air duct are both communicated with the interior of the cabinet body; and the compression refrigeration system comprises a compressor, a gas-liquid separation unit, a condenser, a throttling unit and an evaporator, which are successively connected through a refrigerant pipeline, wherein the refrigerant pipeline is finally connected with the compressor again so as to realize a refrigerant cycle. According to the utility model, through additional arrangement of the compression refrigeration system on the power distribution cabinet, refrigerating capacity is guaranteed, and temperature in the power distribution cabinet can be maximumly decreased; meanwhile, since the circulation air duct is arranged in the power distribution cabinet body, a refrigeration cycle can be rapidly realized.
Description
Technical field
The utility model relates to power distribution cabinet, particularly a kind of compression refrigerating system of power distribution cabinet.
Background technology
in the power distribution cabinet field, interior a large amount of connectors and the various electronic devices and components installed due to power distribution cabinet, and the existence of a large amount of wires is arranged, cause the total resistance value of power distribution cabinet very high, therefore directly cause power distribution cabinet in work, namely in the situation that conduction can be distributed a large amount of heats, temperature in power distribution cabinet is improved suddenly, again because electronic devices and components and the connector of power distribution cabinet inside are very high to the dustproof requirement of power distribution cabinet, therefore power distribution cabinet all adopts sealed type, reducing dust enters in power distribution cabinet, will make so the very difficult discharge power distribution cabinet of heat of the generation in high-low voltage electric power distribution cabinet, traditional heat abstractor is all generally to dispel the heat by the mode that circulating fan is combined with louvre, and the radiating effect of this radiating mode is more limited, can not the interior low-temperature working requirement of stable maintenance power distribution cabinet.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of compression refrigerating system of power distribution cabinet, and cold operation in energy stable maintenance power distribution cabinet has characteristics easy to use simple in structure.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of compression refrigerating system of power distribution cabinet, comprise cabinet and compression refrigerating system, the side of described cabinet arranges circulation air path, the air outlet of circulation air path is arranged at the top of cabinet, the return air inlet of circulation air path is arranged at the below of cabinet, the air outlet of circulation air path and return air inlet all with the cabinet internal communication;
Described compression refrigerating system comprises the compressor that connects successively by refrigerant tubing, gas-liquid separation device, and condenser, throttling arrangement, evaporator, refrigerant tubing finally take back to compressor, complete refrigerant circulation.
Be further: above-mentioned evaporator is installed on the air outlet place of circulation air path, and the air outlet place of circulation air path also is equipped with the circulating fan that blows along cabinet and circulation air path circulation for the cold air of evaporator.
Be further: the condenser end of above-mentioned compression refrigerating system also is equipped with radiator fan.
The beneficial effects of the utility model are:
The compression refrigerating system of the utility model power distribution cabinet by for power distribution cabinet installs compression refrigerating system additional, has guaranteed refrigerating capacity, can reduce to greatest extent the distribution in-cabinet temperature; Meanwhile, for power distribution cabinet is provided with circulation air path, can carry out fast kind of refrigeration cycle.
