Low-voltage electrical appliance cabinet having circular heat-dissipation function

Abstract

The invention discloses a low-voltage electrical appliance cabinet having a circular heat-dissipation function. The low-voltage electrical appliance cabinet comprises an electrical appliance cabinet body, wherein the electrical appliance cabinet body is hinged with a cabinet door by means of hinges, a substrate is horizontally arranged inside the electrical appliance cabinet body, the bottom partinside the electrical appliance cabinet body is provided with a water cooler by means of screws, a circulation pump is arranged on the top part of the water cooler, a cooling pipe is arranged on the circulation pump, the cooling pipe extends upwards after passing through the substrate, the cooling pipe is fixed on the inner wall of the electrical appliance cabinet body by means of hoop members, and the water cooler is fixed connected with the cooling pipe by means of a return pipe. According to the low-voltage electrical appliance cabinet, a radiating plate absorbs heat rapidly, the high-temperature heat of the radiating plate is taken away by using circulating cold water when the cooling pipe flows through the radiating plate, the absorption efficiency is high, the temperature reducing speed is fast, the internal heat of the electrical appliance cabinet is released to the outside by means of a draught fan, the problem of introduction of impurities in the air is solved since the air flows outwards, a flow guiding top is of an arch-shaped structure, the flow guiding effect is good, and backward flow of rainwater is prevented.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to a low-voltage electrical cabinet with the function of circulating heat dissipation. Background technique [0002] The electrical cabinet is a cabinet processed from steel to protect the normal operation of electrical appliances. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. [0003] At present, the low-voltage electrical cabinets on the market generally realize the heat dissipation of the electrical cabinet through the introduction and exhaust of air by the fan. The heat dissipation efficiency is low, and the external impurities are easily introduced during the heat dissipation, which affects the normal operation of the internal electrical appliances of the electrical cabinet. The low-voltage electrical cabinet with circulating heat dissipation function can solve the above exis...
