[0019] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] With reference to Figures 1-4 A modular heat dissipation structure of an online double-conversion high-efficiency energy-saving power supply includes a module frame 1 and a plurality of power supply modules 2. The plurality of power supply modules 2 are arranged in a rectangular array inside the module frame 1. Left and right heat insulation plates 3 are arranged between the upper and lower power supply modules 2. The heat insulation plates 3 are vertically strip-shaped. The module frame 1 is arranged in a semi-open state. The heat insulation plates 3 fill the gaps between the upper and lower power supply modules 2. There is also a certain gap between the left and right power supply modules 2. The gap provides an air channel for ventilation of the power supply module 2 system. The heat insulation plates 3 avoid the exchange of invalid heat between the upper and lower power supply modules 2. It should be noted that the heat insulation plates 3 are not heat insulation materials. They have certain heat conduction performance. The module frame 1 is made of high-strength aluminum alloy profiles. The inside is arranged in a rectangular array with a plurality of standardized power supply modules 2. It supports hot plugging. Double-sided heat insulation plates 3 are arranged between the upper and lower power supply modules. The material is an anodized aluminum plate. It has the functions of structural support and heat conduction. The two sides of the heat insulation plates 3 are kept at a vertical distance of 5 mm from the power supply modules. This forms an air isolation cavity between the upper and lower layers. It effectively blocks about 70% of the radiation heat transfer. At the same time, a vacuum heat plate 4 is embedded in the heat insulation plate. It has an equivalent heat conduction coefficient. Through the heat pipe effect, it transversely leads out the heat of local hot spots. The distance between the left and right adjacent modules is 8 mm. It cooperates with the semi-open side wall of the frame to form a transverse auxiliary air duct. It realizes three-dimensional heat dissipation space.

[0021] Further, the heat insulation plate 3 is internally fixed with several heat plates 4, the heat plates 4 are externally fixed with heat-conducting copper pipes 7, the heat-conducting copper pipes 7 are fixed at both ends of the heat plates 4, the module frame 1 is fixedly installed with heat dissipation fins 5 on the upper side, both ends of the heat-conducting copper pipes 7 are fixedly connected with the upper heat dissipation fins 5, the module frame 1 is fixedly installed with a base 9 on the lower side, the base 9 is arranged to form a certain gap between the module frame 1 and the bottom surface, a plurality of fans one 6 are fixedly installed on the upper side of the heat dissipation fins 5, and the module frame 1 is internally arranged with vertical air ducts corresponding to the fans one 6, which are suitable for "chimney effect" and cooperate with the fans one 6 to greatly improve the smoothness of the vertical airflow of the power module 2. Meanwhile, the heat-conducting copper pipes 7 are arranged to conduct the heat of the heat insulation plate 3 to the heat-conducting copper pipes 7 through the heat plates 4, and then the heat is concentrated on the heat dissipation fins 5 for concentrated heat dissipation. The heat plates 4 are connected with the top heat dissipation fins 5 through the heat-conducting copper pipes 7 with a diameter of 8 mm and a wall thickness of 1 mm. The heat dissipation fins adopt a interdigital fin structure with a single fin height of 30 mm and a spacing of 3 mm, and the total heat dissipation area reaches 1.2 m2 / kW. The bottom base 9 lifts the frame by 30 mm from the ground, cooperates with a plurality of groups of axial flow fans one 6 to form forced convection from bottom to top, the surface of the heat-conducting copper pipes 7 is covered with a graphene coating to reduce the temperature of the heat pipe by 15-20℃ through radiation heat dissipation, and the fan system supports automatic switching of horizontal / vertical / three-way air ducts. When any direction fan fails, the remaining air ducts automatically increase the speed by 30% to compensate for the heat dissipation capacity.

[0022] Further, the module frame 1 is arranged with two dust filters 10 on the left and right sides, the dust filters 10 slide up and down in the module frame 1, and the two sides of the dust filters 10 are arranged with sliding grooves 12 corresponding to the dust filters 10. The arrangement of the dust filters 10 can prevent dust from entering the inside of the module frame 1 and adhering to the power module 2, which not only affects the heat dissipation of the power module 2, but also affects the smoothness of the air duct inside the module frame 1. The detachable dust filters 10 can be easily cleaned and replaced. The left and right side plates are embedded with detachable multi-layer composite dust filters 10 to realize quick disassembly and cleaning through the sliding grooves 12. When the filter is blocked, the differential pressure sensor triggers an alarm.

[0023] Further, a plurality of fans two 8 are fixedly installed on the right side of the module frame 1, the module frame 1 is internally arranged with horizontal air ducts corresponding to the fans two 8, a plurality of fans three 11 are fixedly installed on the rear side of the module frame 1, and the module frame 1 is internally arranged with vertical air ducts corresponding to the fans three 11. The "N+1" structure fans are arranged. When a fan in one air duct direction fails, a second backup can be established to dissipate heat in another air duct direction. The redundant fan design automatically takes over when any fault occurs. Correspondingly, two fan systems can work at the same time to enhance the heat dissipation effect inside the module frame 1.

[0024] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
