Description

A dust-free power distribution cabinet with heat dissipation function

Technical Field

The utility model relates to the technical field of power distribution cabinets, in particular to a dust-free power distribution cabinet with a heat dissipation function.

Background Art

The power distribution cabinet is a commonly used power equipment. With the development of technology, more and more electrical components are installed in the power distribution cabinet, and the size of the power distribution cabinet becomes larger and larger. At present, after long-term use of most power distribution cabinets, dust in the outside air easily enters the inside of the power distribution cabinet through the heat dissipation vents and deposits on the surface of electronic components, which can easily cause failures of electronic components such as circuits, inverters and servers.

In the prior art, a Chinese utility model patent with publication number CN205901081U discloses an ultra-clean dust-free power distribution cabinet, wherein the cabinet body and the glass door of the power distribution cabinet form a completely sealed structure to achieve the purpose of dust prevention, and the heat inside the power distribution cabinet is dissipated through a heat sink filled with water.

However, in actual use, due to the close arrangement of equipment and poor ventilation conditions inside this type of distribution cabinet, during the peak summer period, the number of electrical equipment failures and burns caused by increased temperature inside the box remains high, seriously reducing the power supply reliability.

In the prior art, a Chinese utility model patent with publication number 201220652534.9 discloses a water-cooled heat dissipation system for a power distribution cabinet, comprising a cabinet body, a circulating fan for circulating air inside the cabinet body installed above the cabinet body side panel; a water-cooled heat dissipation system is also installed on the top of the cabinet body, specifically comprising a heat exchanger installed on the top of the cabinet body to transfer 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, the cold water coil is connected to a return valve, a water tank, a cooling tower, a circulating water pump (9) in sequence through a pipeline, and finally connected back to the cold water coil of the heat exchanger to complete the circulation. The utility model can reduce the temperature inside the power distribution cabinet to the maximum extent by circulating cooling water; because the entire system adopts circulating water and a heat exchanger that does not pollute the environment, it not only has high heat dissipation efficiency, but also high environmental benefits, and is an energy-saving and environmentally friendly method.

Although the heat dissipation efficiency is high, the heat dissipation devices are all installed on the top of the cabinet. The electronic components at the bottom of the cabinet are far away from the heat dissipation devices, and the heat dissipation effect is far less than that of the electronic components at the top, and the heat dissipation effect is not uniform. When the work is busy, the heat of the electronic components at the bottom cannot be completely dissipated, and the heat will accumulate and gradually rise, and the electrical components at the bottom of the cabinet will be overheated and damaged; and the heat dissipation through the cooling tower makes the structure of the water-cooled heat dissipation system of the entire distribution cabinet complex, and the installation process is complicated in actual use.
