DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] See also Figure 1 - Figure 5 As shown, a novel high-voltage frequency converter device comprises:

[0029] A housing 1, a high-voltage inverter is placed inside the housing 1, a back plate 2 is fixedly connected to the back of the housing 1, and a plurality of heat dissipation holes are opened on the back plate 2;

[0030] A first heat dissipation component, which is arranged on the back of the housing 1;

[0031] A second heat dissipation component, which is arranged on the top of the housing 1;

[0032] Frame 11, frame 11 is split and hinged to the back of the housing 1, and a second heat dissipation fan 12 is fixedly connected to the middle of the frame 11;

[0033] The fixing component is arranged on the frame 11 .

[0034] The heat emitted by the high-voltage inverter inside the shell 1 is transferred to the outside through the back panel 2 and the heat dissipation holes. At this time, the first heat dissipation component, the second heat dissipation component and the second heat dissipation fan 12 can help the back panel 2 to dissipate heat and quickly reduce the heat dissipation efficiency of the back panel 2. When the user needs to inspect the back parts of the shell 1, the frame 11 can be opened through the fixing component to expose the heat dissipation parts on the back of the shell 1 for inspection.

[0035] The first heat dissipation component includes a cold water tank 3 fixedly installed on the bottom of the inner wall of the shell 1, and a plurality of heat dissipation plates 4 are fixedly connected to the cold water tank 3. The heat dissipation plates 4 are hollow. A hot water tank 5 connected to the heat dissipation plates 4 is fixedly connected to the top of the inner wall of the shell 1, and the side walls of the heat dissipation plates 4 are fixedly connected to the back plate 2.

[0036] The cold water in the cold water tank 3 flows through the heat sink 4, and the heat of the heat sink 4 is transferred to the cold water. The cold water absorbs the heat and becomes hot water, and then the hot water enters the hot water tank 5, thereby quickly reducing the temperature of the heat sink 4 and then reducing the temperature of the back plate 2.

[0037] The heat dissipation efficiency of the heat dissipation plate 4 is related to the heat dissipation area. In order to increase the surface area of ​​the heat dissipation plate 4, the heat dissipation plate 4 is arranged in a wave shape.

[0038] The second heat dissipation component includes a heat dissipation pipe 6 fixedly installed on the top of the shell 1, one end of the heat dissipation pipe 6 is fixedly connected to the hot water tank 5, the other end of the heat dissipation pipe 6 is fixedly connected to a return pipe 9, the end of the return pipe 9 is fixedly connected to the cold water tank 3, and a water pump 10 is arranged on the return pipe 9. The top of the shell 1 is fixedly connected to a mounting frame 7, the heat dissipation pipe 6 is arranged inside the mounting frame 7, and the mounting frame 7 is fixedly connected to a first heat dissipation fan 8.

[0039] The water pump 10 provides power for the heat dissipation water flow. After the hot water in the hot water tank 5 enters the heat dissipation pipe 6, the first heat dissipation fan 8 dissipates heat to the heat dissipation pipe 6. Then the hot water in the heat dissipation pipe 6 reduces its temperature and flows into the return pipe 9. The cold water flows into the cold water tank 3 via the return pipe 9, thereby completing the heat dissipation of the cooling water.

[0040] In order to enable the heat dissipation pipe 6 to dissipate heat quickly, the heat dissipation pipe 6 is arranged in a spiral disk shape.

[0041] The fixing assembly includes a telescopic rod 13 hinged on one frame 11 and a positioning rod 14 fixedly installed on another frame 11. The telescopic rod 13 includes a telescopic cylinder 131 hinged to the frame 11, a pull rod 132 slidably inserted at the end of the telescopic cylinder 131, and a spring 133 arranged inside the telescopic cylinder 131. The two ends of the spring 133 are respectively abutted against the inner wall of the telescopic cylinder 131 and the side wall of the pull rod 132, and the end of the pull rod 132 is clamped with the positioning rod 14.

[0042] The user can open the frame 11 to expose the heat dissipation parts on the back of the shell 1, which is convenient for the user to inspect and repair the heat dissipation parts. When the user needs to open the frame 11, pull the pull rod 132 downward, the pull rod 132 compresses the spring 133, and then the end of the pull rod 132 is disengaged from the positioning rod 14. At this time, rotate the telescopic rod 13 to drive the pull rod 132 away from the positioning rod 14, release the pull rod 132, and the compressed spring 133 is reset to drive the pull rod 132 back to the inside of the telescopic tube 131. At this time, the telescopic rod 13 is no longer stuck between the two frames 11. At this time, rotate the frame 11 to expose the parts on the back of the shell 1, which is convenient for the user to inspect and repair.
