Air switch mounting plate cooling structure using siphon

Abstract

The invention provides an air switch mounting plate cooling structure utilizing siphoning, which comprises a power distribution cabinet and a cooling box, a circulating cooling mechanism is arranged in the cooling box, a resistor pressurizing mechanism is arranged on the side surface of the power distribution cabinet, a mounting plate is arranged on one side in the power distribution cabinet in a matched manner, and an air switch is fixedly mounted on one side of the mounting plate. The circulating cooling mechanism comprises a water storage tank A, a semiconductor chilling plate, a water suction pump, a liquid guide pipe, a hollow shell and a gear A. The water storage tank A is fixedly installed on one side in the cooling tank, the semiconductor chilling plate is fixedly installed on the lower portion in the water storage tank A, a water storage tank B is fixedly installed on the other side in the cooling tank, and the water storage tank A is higher than the water storage tank B; and a U-shaped pipe is fixedly mounted between the water storage tank A and the water storage tank B. Cooling water can be circularly cooled by using a siphon principle, so that the cooling efficiency and quality of the cooling water on the mounting plate and the air switch are improved, the air switch is prevented from being broken due to high temperature during use, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the field of temperature reduction of the installation board, in particular to an air-opening installation board cooling structure utilizing siphon. Background technique [0002] The air switch is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. The air switch is a very important electrical appliance in the low-voltage power distribution network and electric drive system. It integrates control and multiple protection functions. In addition to completing the contact and breaking of the circuit, it can also protect the short circuit, severe overload and undervoltage of the circuit or electrical equipment, and can also be used to start the motor infrequently; [0003] The mounting plate of the air switch is a fixed device for supporting the air switch. When the heat generated by the air switch cannot be dissipated through the mounting plate, an open circuit will occur. ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a cooling structure of air switch mounting plate using siphon, to solve the problem that the mounting plate on the side of the air switch proposed in the above background technology cannot disperse and cool the heat generated by the air switch when it is installed. As a result, the air switch is susceptible to temperature interference during use and cannot operate normally, which makes it unable to better protect electronic components such as short circuits, severe overloads, and undervoltages inside the power distribution cabinet.
