Abstract

A power distribution cabinet heat-dissipation system comprises a cabinet body. The whole cabinet body is a hollow cuboid structure. A circulating fan used for circulation of the air inside the cabinet body is installed above a side plate of the cabinet body. The top of the cabinet body is also provided with a water-cooling heat dissipation system. Specifically, the system contains a heat exchanger which is installed on the top of the cabinet body and is used for transferring heat inside the cabinet body to the outside of the cabinet body. A cooling section of the heat exchanger is provided with a cold water coil which is successively connected to a back-water valve, a water tank, a cooling tower, a circulating water pump and finally back to the cold water coil of the heat exchange so as to finish the circulation. Through cyclic cooling of water, the temperature in a power distribution cabinet can be reduced to the maximum. By cycling use of water and the heat exchanger which has no pollution to the environment in the whole system, the system has advantages of high heat dissipation efficiency and high environmental benefit, and belongs to an energy-saving and environmental protection mode.

Description

A kind of power distribution cabinet cooling system
Technical field
The present invention relates to power distribution cabinet, particularly a kind of power distribution cabinet cooling system.
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 power distribution cabinet cooling system, 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 power distribution cabinet cooling system, comprises cabinet, and cabinet entirety is the rectangular structure of hollow, and side cabinet top is provided with the circulating fan for cabinet inner air is circulated; The top of cabinet is also provided with water-cooling heat radiating system, the concrete heat exchanger to cabinet outside by transfer of heat in cabinet that is installed on cabinet top that comprises, the cooling section of heat exchanger is provided with chilled water coil, chilled water coil connects back-water valve (BWV) successively by pipeline, water tank, cooling tower, circulating water pump, finally take back the chilled water coil to heat exchanger, complete circulation.
Further: above-mentioned water tank is also provided with the water injection valve for retaining.
Further: above-mentioned heat exchanger comprises the heat absorbing end for absorbing cabinet intimate heat and the colling end for heat absorbing end dissipation of heat is fallen, the heat absorbing end of heat exchanger is positioned at cabinet inside, and the colling end of heat exchanger is positioned at cabinet outside.
The invention has the beneficial effects as follows:
The water-cooling heat radiating system of power distribution cabinet of the present invention, by water is carried out to circulating cooling, can reduce distribution in-cabinet temperature to greatest extent; Because whole system has adopted the heat exchanger of cycling use of water and environmentally safe, therefore, not only radiating efficiency is high, and environmental benefit is also high simultaneously, belongs to a kind of mode of energy-conserving and environment-protective.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Description of reference numerals:
1-cabinet, 2-circulating fan, 3-heat exchanger, 4-circulating water pump, 5-cooling tower, 6-back-water valve (BWV), 7-water injection valve, 8-water tank.
Embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, power distribution cabinet cooling system of the present invention, comprises cabinet 1, and cabinet 1 entirety is the rectangular structure of hollow, and cabinet 1 side plate top is provided with the circulating fan 2 for cabinet inner air is circulated; The top of cabinet 1 is also provided with water-cooling heat radiating system, the concrete heat exchanger 3 to cabinet outside by transfer of heat in cabinet that is installed on cabinet 1 top that comprises, the cooling section of heat exchanger 3 is provided with chilled water coil, chilled water coil connects back-water valve (BWV) 6 successively by pipeline, water tank 8, cooling tower 5, circulating water pump 4, finally take back to the chilled water coil of heat exchanger 3, complete circulation.
Above-mentioned water tank 8 is also provided with the water injection valve 7 for retaining;
Above-mentioned heat exchanger 3 comprises the heat absorbing end for absorbing cabinet intimate heat and the colling end for heat absorbing end dissipation of heat is fallen, and the heat absorbing end of heat exchanger 3 is positioned at cabinet inside, and the colling end of heat exchanger is positioned at cabinet outside.
By reference to the accompanying drawings the preferred embodiment for the present invention is explained in detail above, but the invention is not restricted to above-mentioned execution mode, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
Do not depart from the spirit and scope of the present invention and can make many other changes and remodeling.Should be appreciated that and the invention is not restricted to specific execution mode, scope of the present invention is defined by the following claims.
