Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency switching power supplies, in particular to a liquid-cooled high-frequency switching power supply box. Background Art

[0002] During the operation of a high-frequency switching power supply, electrical components such as the rectifier components and transformer components in its electrical system will generate heat, which will cause the operating temperature of the high-frequency switching power supply to increase. Therefore, in order to prevent the high-frequency switching power supply from malfunctioning due to high temperature, a heat dissipation mechanism is generally set in the casing of the high-frequency switching power supply to dissipate heat and cool the electrical components through the heat dissipation mechanism.

[0003] Common high-frequency switching power supply heat dissipation mechanisms can be divided into air-cooled type using fan heat dissipation or liquid-cooled type using coolant heat dissipation according to their heat dissipation methods. Among them, the air-cooled heat dissipation mechanism requires the installation of air inlets and outlets on the high-frequency switching power supply box, which will cause dust to accumulate in the power supply box, which will directly affect the service life of the electrical components over a long period of time. The liquid-cooled heat dissipation mechanism generally sets cooling pipes for coolant circulation near the electrical components in the power supply box to cool down. However, since the cooling pipes are prone to fouling and clogging after long-term use, affecting the heat dissipation effect, the pipes need to be cleaned regularly. Conventional cooling pipes are relatively troublesome to install and disassemble, and are prone to wear and tear after many installation and disassembly times, affecting their sealing performance.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

[0008] Preferably, the guide column has a plurality of direction-changing nodes for the cooling pipes, and the direction-changing nodes are evenly arranged from top to bottom or from bottom to top, so that the cooling pipes form a multi-layer structure.

[0010] Preferably, a cooling pipe seat is provided on the side wall of the box body, and both ends of the cooling pipe extend out of the box body from the cooling pipe seat to facilitate circulating cooling.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example

[0024] See also Figures 1 to 2 A liquid-cooled high-frequency switching power supply box includes a box body 1 with an open top, a box cover 2 on the box body 1, a cooling pipe 3 and a plurality of electrical components are arranged in the box body, and the electrical components are arranged in rows and gaps are left around each row of electrical components. A plurality of guide columns 31 are also provided in the box body, and each guide column is evenly arranged around each row of electrical components. The cooling pipe 3 is a hose, and the cooling pipe changes direction with each guide column as a node so as to be evenly distributed around the electrical components.

[0025] The guide column 31 has a plurality of direction-changing nodes for the cooling pipes, and the direction-changing nodes are evenly arranged from top to bottom or from bottom to top, so that the cooling pipes form a multi-layer structure.

[0026] The number of cooling tube layers around the electrical component is positively correlated with the heat dissipation of the electrical component.

[0027] A cooling pipe seat 11 is provided on the side wall of the box body 1, and both ends of the cooling pipe extend out of the box body from the cooling pipe seat to facilitate circulating cooling. The cooling pipe seat is provided with a through hole that matches the diameter of the cooling pipe to facilitate the cooling pipe to pass through.

[0028] A hinge seat 13 is fixedly connected to the outer side of the top of the box body 1, and a hinge shaft 131 is installed on the hinge seat. The box cover 2 is connected to the box body through the hinge shaft.

[0029] A buckle plate 21 is fixed to one end of the box cover 2 away from the hinge shaft 131. The buckle plate is arranged perpendicular to the box cover and extends downwardly to the box body. A lock buckle 12 is installed on the side of the box body 1 corresponding to the buckle plate. A lock hole adapted to the lock buckle is opened on the buckle plate to facilitate the fixation of the box cover and the box body.

Since the cooling pipe is a flexible tube, it is easy to remove. When reinstalling after cleaning, it is only necessary to pay attention to not allowing the cooling pipe at the guide column turning node to be too large and thus flattened. Slight pressure will not affect the flow of coolant therein. The retractable box cover further improves the convenience of installation and removal of the cooling pipe, and its operation is faster than that of a conventional power box shell fixed with bolts.
