Problems solved by technology

[0002] In the field of power distribution cabinets, due to the installation of a large number of connectors and various electronic components in the power distribution cabinet, and the existence of a large number of wires, the total resistance of the power distribution cabinet is very high, which directly leads to the failure of the power distribution cabinet. When working, a large amount of heat will be emitted in the case of conduction, which will suddenly increase the temperature in the power distribution cabinet, and because the electronic components and connectors inside the power distribution cabinet have high dustp

Example Embodiment

[0013] The present invention will be described in more detail below with reference to the drawings and embodiments.

[0014] As shown in the figure, the heat dissipation system of the power distribution cabinet of the present invention includes a cabinet body 1. The cabinet body 1 has a hollow rectangular parallelepiped structure as a whole. A circulating fan 2 for circulating air inside the cabinet body is installed above the side plate of the cabinet body 1; A water cooling system is also installed on the top of the cabinet 1, specifically including a heat exchanger 3 installed on the top of the cabinet 1 to transfer the heat inside the cabinet to the outside of the cabinet. The cooling section of the heat exchanger 3 is provided with cold water coils and cold water pans. The pipe is connected to the water return valve 6, the water tank 8, the cooling tower 5, and the circulating water pump 4 in sequence through the pipeline, and finally connected back to the cold water coil of ...

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

technical field [0001] The invention relates to a power distribution cabinet, in particular to a cooling system for a power distribution cabinet. Background technique [0002] In the field of power distribution cabinets, due to the installation of a large number of connectors and various electronic components in the power distribution cabinet, and the existence of a large number of wires, the total resistance of the power distribution cabinet is very high, which directly leads to the failure of the power distribution cabinet. When working, a large amount of heat will be emitted in the case of conduction, which will suddenly increase the temperature in the power distribution cabinet, and because the electronic components and connectors inside the power distribution cabinet have high dustproof requirements for the power distribution cabinet , so the power distribution cabinets are all sealed to reduce dust entering the power distribution cabinet, which will make it difficult f...
