Description

Technical Field

[0001] This utility model relates to the field of high-frequency switching power supply technology, and in particular to a high-frequency switching power supply with a novel heat dissipation and installation structure. Background Technology

[0002] High-frequency switching power supplies, as core components of electronic power equipment, are widely used in communication base stations, industrial equipment, and new energy fields. They achieve electrical energy conversion through high-frequency switching technology; however, under long-term high-load conditions, heat dissipation performance and structural stability become key issues restricting equipment reliability. Therefore, high-frequency switching power supplies have very high requirements in terms of heat dissipation structure and installation precision.

[0003] Current high-frequency switching power supplies still have certain shortcomings in terms of heat dissipation and installation structure. From the perspective of heat dissipation, most high-frequency switching power supplies adopt air-cooled heat dissipation structure, which has low cooling efficiency and is difficult to meet the requirements of high-intensity working environment. Therefore, in order to improve the heat dissipation effect, some high-frequency switching power supplies introduce water-cooled structure in the power supply box, distributing coolant pipes in the power supply box to reduce the temperature inside the box by water cooling, thereby ensuring the heat dissipation of electrical components. However, in the high temperature weather of summer and in the environment of long-term operation, its heat dissipation effect is still difficult to meet the requirements. Secondly, from the perspective of installation structure, the busbars and transformers are usually rigidly assembled during production, which is cumbersome to install and disassemble, inefficient, and requires violent disassembly during inspection or maintenance, which can easily damage various electrical components.

[0004] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Utility Model Content
