Abstract
A rapid refrigeration system of a power distribution cabinet comprises a cabinet body and a compression refrigeration system; one side of the cabinet body is provided with a circulating air duct; the air outlet of the circulating air duct is arranged at an upper portion of the cabinet body; the return air inlet of the circulating air duct is arranged at a lower portion of the cabinet body; the air outlet and the return air inlet of the circulating air duct are both communicated with the interior of the cabinet body; and the refrigeration system comprises a compressor, a gas-liquid separator, a condenser, a throttling device and an evaporator which are connected with one another through a refrigerant pipeline which finally goes back and is connected with the compressor, such that refrigerant circulation can be completed. According to the rapid refrigeration system of the power distribution cabinet of the invention, the power distribution cabinet is provided with the compression refrigeration system, and therefore, refrigeration capacity can be ensured, and temperature inside the power distribution cabinet can be decreased to the largest extent; and at the same time, the power distribution cabinet is provided with the circulating air duct, and therefore, fast refrigeration circulation can be realized.
Description
Technical field
The present invention relates to power distribution cabinet, particularly a kind of rapid refrigerating system of power distribution cabinet.
Background technology
In power distribution cabinet field, due to interior a large amount of connectors and the various electronic devices and components installed of power distribution cabinet, and there is the existence of a large amount of wires, cause the total resistance value of power distribution cabinet very high, therefore directly cause power distribution cabinet in work, the in the situation that of conduction, can distribute 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 that the mode of being combined with louvre by circulating fan is dispelled the heat, and the radiating effect of this radiating mode is more limited, the low-temperature working requirement in can not stable maintenance power distribution cabinet.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of rapid refrigerating system of power distribution cabinet, cold operation in energy stable maintenance power distribution cabinet, has feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of rapid 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 cabinet internal communication;
Described compression refrigerating system, comprises the compressor connecting successively by refrigerant tubing, gas-liquid separation device, and condenser, throttling arrangement, evaporator, refrigerant tubing finally takes back to compressor, completes refrigerant circulation.
Further: above-mentioned evaporator is installed on the air outlet place of circulation air path, the air outlet place of circulation air path be also provided with for by the cold air of evaporator along cabinet and the circulation air path circulating fan blowing that circulates.
Further: the condenser end of above-mentioned compression refrigerating system is also provided with radiator fan.
The invention has the beneficial effects as follows:
The rapid refrigerating system of power distribution cabinet of the present invention, by for power distribution cabinet installs compression refrigerating system additional, has guaranteed refrigerating capacity, can reduce to greatest extent distribution in-cabinet temperature; Meanwhile, for power distribution cabinet is provided with circulation air path, can carry out fast kind of refrigeration cycle.
