Description

Technical Field

[0001] The present invention relates to the field of electrical technology, and particularly to an inductor box. Background Art

[0002] The inductor box is an important part of the inverter structure. It is responsible for placing the inductor and helping the inductor dissipate heat so that the inductor can work properly. However, when the inverter voltage is high and the power is large, the inductor is prone to generate a large amount of heat. Although there is a cooling fan inside the inverter, a single cooling fan is often difficult to effectively dissipate heat, especially the heat of the inductor part. There are great potential safety hazards.

[0003] Therefore, how to improve the existing inverter structure to overcome the above problems is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] An object of the present invention is to provide a high-voltage AC inductor box with reasonable layout and good heat dissipation.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a high-voltage AC inductor box, characterized in that: it includes a box body, at least two accommodating grooves with open tops are spaced in the box body, the accommodating grooves are cylindrical, and the accommodating grooves are adapted to place annular inductors;

[0006] The outer wall of the box body is a hollow structure, a cooling chamber is formed inside the outer wall of the box body, and cooling pipes are distributed throughout the cooling chamber; the cooling pipes are adapted to be connected to a cooling device, and a cooling medium is adapted to flow through the cooling pipes. The cooling device exchanges heat through the cooling medium in the cooling pipes to achieve cooling of the inductor box.

[0007] Specifically, the cooling medium is water, and the cooling device includes a water pump, an inlet pipe, an outlet pipe, and a radiator fin group. A support frame is fixedly arranged on the box body, the water pump is fixedly arranged on the support frame, the inlet pipe is connected to one end of the water pump, and the inlet pipe is connected to one end of the cooling pipe. The outlet pipe is connected to the other end of the cooling pipe, and the outlet pipe flows through the radiator fin group and then is connected to the other end of the water pump. The radiator fin group is fixedly arranged and adapted to be aligned with the cooling fan inside the inverter; the cooling medium flows out of the water pump, successively passes through the outlet pipe, the cooling pipe, the outlet pipe, and the radiator fin group, and then returns to the water pump to complete the water cycle, thereby taking away the heat generated inside the box body.

[0008] As an improvement, the lowest part of the cooling chamber is recessed to form a water collecting tank, and a water immersion sensor is installed in the water collecting tank. The arrangement of the water collecting tank and the water immersion sensor is a precautionary structure. In case the cooling pipe leaks, the water collecting tank can collect the leaked water for a period of time to prevent the leaked water from flowing out of the inductor box and causing a safety accident; while the water immersion sensor can sense the water leakage situation immediately, so that people can stop running the inverter immediately and deal with the water leakage.

[0009] Preferably, a connector is provided on the outer wall of the box body. The connector communicates with the cooling chamber. Both ends of the cooling pipe are located at both ends of the connector respectively. The water inlet pipe and the water outlet pipe are connected to both ends of the cooling pipe through the connector. The connection method of the cooling pipe is optimized to make its layout more reasonable and the connection more convenient.

[0010] As an improvement, a skirt is provided on the peripheral side of the upper end of the box body. The skirt extends forward to the radiator fin group, and the radiator fin group is fixedly arranged on the skirt; a plurality of mounting posts extending upward are provided on the skirt, and the mounting posts are suitable for fixedly connecting to the top of the inverter. The skirt is mainly used to strengthen the inductor box and make the cooling device and the inductor box an integrated structure; the arrangement of the mounting posts makes the inductor box suspended when installed inside the inverter, increasing the heat dissipation space on both its upper and lower sides and improving its heat dissipation efficiency.

[0011] Compared with the prior art, the advantages of the technical solution of the present invention are as follows:

[0012] 1. The cylindrical accommodation groove has the largest heat dissipation area under the box body voltage and power, which is beneficial to the heat dissipation of the inductor box.

[0013] 2. The cooling pipe and the cooling device of this solution are an integrated water cooling device, which does not need to be connected to an external water pipe, and has the advantages of compact structure, small volume and convenient installation.

[0014] 3. The inside of the box body of this solution is covered with cooling pipes, which increases the contact area with the box body, speeds up the heat conduction rate and improves the cooling efficiency.

[0015] 4. A radiator fin group is provided and combined with the heat dissipation fan inside the inverter as a heat exchange component. Its structure is similar to that of a CPU radiator, and it can maximize the heat dissipation efficiency in a limited space. BRIEF DESCRIPTION OF THE DRAWINGS
