Water-cooled radiator for sealed power distribution cabinet

Abstract

Disclosed is a water-cooled radiator for a sealed power distribution cabinet. The water-cooled radiator comprises a high-voltage sealed power distribution cabinet which is communicated with a temporary storage water tank through a water circulation pipeline A and connected with a refrigeration ice water machine through a water circulation pipeline B, and the water circulation pipeline A and the water circulation pipeline B are in heat interaction connection with a heat exchanger in the high-voltage sealed power distribution cabinet. Axial flow fans are arranged on the upper portion of the high-voltage sealed power distribution cabinet. A water-cooled circulation radiation method is utilized, heat in the sealed power distribution cabinet is subjected to heat exchange with water through the heat exchanger in the cabinet, redundant heat is carried by water to be discharged into the temporary storage water tank along a water outlet pipe to be cooled and filtered and enters the ice water machine to be cooled fully through a cooling system, and water is fed into a water inlet pipe through a water pump to cool and radiate the cabinet circularly. The water-cooled radiator has the advantage of a good radiation effect.

Problems solved by technology

[0002] In the field of high and low voltage 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 high When the low-voltage power distribution cabinet is working, that is, it will emit a large amount of heat in the case of conduction, which will cause the temperature in the power distribution cabinet to increase suddenly, and because the electronic components and connectors inside the power distribution cabinet are protected against the power distribution cabinet. The dust requirements are very high, so the power distribution cabinets are all sealed to reduce dust entering the power distribution cabinet, which will make it difficult for the heat generated in the high and low voltage power distribution cabinets to discharge from the power distribution cabinet. Nowadays, the commonly used heat dissipation method It is to install a high-power axial flow fan inside the cabinet, and set up cooling holes, so that the wind blown by the axial flow fan forms an air-cooling cycle, and quickly blows the heat inside the high and low voltage power distribution cabinet out of the body to achieve the effect of heat dissipation. However, this cooling method has obvious disadvantages: first, it destroys the sealing of the high and low voltage power distribution cabinet, so that dust and dust with static electricity enter the power distribution cabinet through the fan and cooling holes, and are attached to the power distribution cabinet through the circulation of the fan. Various electronic components, connectors or wires directly affect the insulation of the power distribution cabinet, and even cause a short circuit to cause an accident; the second disadvantage is that the heat dissipation is slow. Try to maintain the airtightness of the cabinet as much as possible. The number of axial flow fans installed is small, and the diameter of the heat dissipation holes dug is small. Therefore, the air cooling cycle is blocked by the electronic components inside the cabinet and various tray baffles, resulting in many air cooling dead angles, which cannot dissipate heat. , so the cooling effect is poor
