High-temperature alarm type industrial switching power supply

Abstract

The invention discloses a high-temperature alarm type industrial switching power supply which comprises a switching power supply cabinet body and a cabinet door arranged on the switching power supplycabinet body. The switching power supply cabinet body is of a rectangular box body structure, and the interior of a box body of the switching power supply cabinet body is divided into a water storagecavity and an installation cavity through a partition plate. A water inlet channel and a drainage channel are formed on the front side wall of the water storage cavity at the lower side of the partition plate, a water inlet channel sealing cover and a drainage channel sealing cover are fixedly installed at the front ends of the pipe bodies of the water inlet channel and the drainage channel respectively, a set of installation holes are formed in the right side of a plate body of the partition plate, and a water outlet pipe and a water return pipe are respectively and fixedly installed in the hole bodies. The heat dissipation grooves are formed in the plate bodies of the rear side wall, the left side wall and the right side wall of the switching power supply cabinet body, and the water diversion ropes are arranged in the heat dissipation grooves, so that water is guided to the upper ends of the heat dissipation grooves under the action of the water diversion ropes, the heat exchange area between the water in the heat dissipation grooves and an inner cavity of the switching power supply cabinet body is effectively increased, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field related to switching power supplies, in particular to a high-temperature alarm-type industrial switching power supply. Background technique [0002] Switching power supply, also known as switching mode power supply, or SMPS for short, is also called switching power supply and switching converter. It is a high-frequency power conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of switching power supply is mostly AC power supply (such as mains) or DC power supply, and the output is mostly equipment that needs DC power supply, such as personal computer, and switching power supply converts the voltage and current between the two, while the traditional industrial Due to its large size and high heat generation, the type switching power supply needs to be equipped with special...

Problems solved by technology

The input of switching power supply is mostly AC power supply (such as mains) or DC power supply, and the output is mostly equipment that needs DC power supply, such as personal computer, and switching power supply converts the voltage and current between the two, while the traditional industrial Due to its large size and high heat generation, the type switching power supply needs to be equipped with special heat dissipation equipment for heat dissipation. However, the traditional heat dissipation method basically uses heat dissipation holes on its shell and is equipped with heat dissipation fans. Heat dissipation, not only the heat dissipation effect is poor, but also due to the existence of heat dissipation holes, and the dust content of industrial plants is generally high, which leads to a large amount of dust easily sticking to the internal electrical components, which affects the normal use of its devices
