Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to an ACDC switching power supply which is convenient for cleaning heat dissipation holes. Background Art

[0002] In the field of power electronics, ACDC, DCDC and switching power supplies are three common power conversion technologies. They have their own characteristics in application and provide the required power for different devices. ACDC power supplies are widely used in IT equipment such as computers, servers, routers, etc. These devices require stable DC voltage to drive internal circuits and chips. ACDC power supplies can provide stable DC voltage to ensure the normal operation of the equipment.

[0003] A Chinese utility model patent with publication number CN218071326U discloses an AC-DC power supply box, including a box frame, the box frame is a rectangular frame, the box frame includes a bottom plate, a first side wall and a second side wall; the first side wall extends vertically upward along the first side of the bottom plate to form a first vertex and a second vertex of the first side wall, the second side wall extends vertically upward along the second side of the bottom plate to form a third vertex and a fourth vertex of the second side wall, and the first side and the second side are two opposite sides of the bottom plate. The first vertex and the second vertex are connected by a first connecting beam, and the second vertex and the fourth vertex are connected by a second connecting beam to form a first opening opposite to the bottom plate, a second opening surrounded by the first connecting beam, the first side wall, the second side wall and the bottom plate, and a third opening surrounded by the second connecting beam, the first side wall, the second side wall and the bottom plate. A power module and a mainboard are fixedly installed in the box frame, the first opening is connected to a first cover plate, and shock-absorbing cotton strips are provided at the connections between the first cover plate and the first connecting beam, the second connecting beam, the first side wall, and the second side wall; a plurality of exhaust fans are provided in the box frame at the second opening, the second opening is connected to a second cover plate, and the third opening is connected to a third cover plate, and heat dissipation holes are provided at positions on the second cover plate and the third cover plate corresponding to the plurality of exhaust fans.

[0004] In the above technology, the cooling fan can drive the flow of air inside and outside the box frame, and the box frame components and the AC-DC power supply body are cooled by the rapid flow of air. The inventor believes that the following technical defects exist: during daily use, dust, catkins and other debris are easily present in the air. After long-term use, the area around the heat dissipation holes is easily covered with agglomerated dust, flocs and other debris. If they are not cleaned, the heat dissipation effect of the AC-DC power supply will be affected. The above technology does not provide a corresponding structure for cleaning the heat dissipation holes. Users can only clean the debris on the heat dissipation holes with cleaning tools such as shoe brushes, and the cleaning efficiency is low. In addition, cleaning tools such as shoe brushes can only clean the heat dissipation holes on the outside of the cover plate. The cover plate has a certain thickness, and the debris around the heat dissipation holes on the inside of the cover plate is not easy to clean. Therefore, the cleaning effect of cleaning tools such as shoe brushes is limited. Incomplete cleaning of the heat dissipation holes will still affect the heat dissipation effect of the AC-DC power supply. Therefore, corresponding improvements to the relevant technology are needed.
