It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] See Figures 1 to 4The water-cooled inverter of the embodiment of the present invention includes a chassis 1, a water-cooling box 2 and a water-cooling plate 3. The water-cooling plate 3 is fixed to the chassis 1, and a mounting plate 33 is attached to one side of the water-cooling plate 3. The water-cooling box 2 is arranged on one side of the chassis 1. The water-cooling plate 3 is connected to a first water pipe port 31, which passes through the chassis 1 and is placed on the water-cooling box 2. The water-cooling box 2 is also provided with a second water pipe port 32, which is connected to the first water pipe port 31 through a water pipe.

[0019] In the above embodiment, the entire device is primarily composed of a chassis 1, a water-cooling box 2, and a water-cooling plate 3. The chassis 1 serves as the main frame, and the four corners of the water-cooling plate 3 are secured to the chassis 1 via screw threads. The water-cooling plate 3 is secured within the chassis 1, with a mounting plate 33 attached to one side of the water-cooling plate 3, using methods including but not limited to gluing. The inverter's main electronic components are mounted on the mounting plate 33 to ensure efficient heat transfer.

[0020] The water-cooling plate 3 is provided with a first water pipe opening 31, which penetrates the wall of the chassis 1 and extends directly into the water-cooling box 2 on one side of the chassis 1. The water-cooling box 2 is attached to the side of the chassis 1 via a threaded connection. A second water pipe opening 32 is provided on the water-cooling box 2, which is connected to the first water pipe opening 31 via a pipe, forming the starting and ending points of a coolant circulation loop.

[0021] Specifically, the second water pipe opening 32 is connected to a micro-water pump, which drives the coolant through the circulation loop. The coolant enters the water-cooled plate 3 through the first water pipe opening 31, absorbs heat transferred from the mounting plate 33, and then returns to other components of the cooling system (such as the radiator or heat exchanger) through the second water pipe opening 32. Driven by the micro-water pump, it re-enters the water-cooled plate 3, forming a continuous cycle. This entire structure achieves efficient heat dissipation from the inverter through the circulation of coolant in a closed loop, ensuring its stability and reliability during long-term operation.

[0022] See Figures 1 to 4 In another embodiment, the chassis 1 is further provided with ventilation holes 11, which are in communication with the water cooling box 2 to promote air circulation and assist in heat dissipation.

[0023] See Figures 1 to 4In another embodiment, the water-cooled plate 3 is provided with a plurality of through holes 34. First, the plurality of through holes 34 can increase the contact area between the water-cooled plate 3 and the coolant, thereby improving the heat exchange efficiency, so that the heat generated by the inverter can be absorbed and carried away by the coolant more quickly. Secondly, the design of the through holes 34 helps the coolant to form a more uniform flow inside the water-cooled plate 3, avoiding problems such as local overheating or uneven cooling, and ensuring the stability and consistency of the overall heat dissipation effect of the inverter. In addition, the through holes 34 can also reduce the weight of the water-cooled plate 3 to a certain extent, while maintaining its structural strength and heat dissipation performance, which is conducive to the lightweight design and optimization of the entire machine.

[0024] See Figures 1 to 4 In another embodiment, the water-cooling plate 3 is integrally formed. The overall structure of the integrally formed water-cooling plate 3 is more compact and stable, which reduces gaps and potential water leakage risks caused by assembly and improves the reliability and durability of the entire machine.

[0025] See Figures 1 to 4 In another embodiment, ventilation holes 12 are provided at the bottom of the side panel of the chassis 1, and the ventilation holes 12 are regularly arranged in an arrow shape, pointing to the cabinet door of the chassis 1. Multiple sets of fans 4 are provided on the top of the chassis 1, and the blowing direction of the fans 4 is from the top to the bottom of the chassis 1. The ventilation holes 12 provided at the bottom of the side panel of the chassis 1 are regularly arranged in an arrow shape, pointing to the cabinet door of the chassis 1, which is convenient for the staff to identify the cabinet door. At the same time, it enhances the air circulation inside the chassis 1 and improves the heat dissipation efficiency. The multiple sets of fans 4 provided on the top of the chassis 1 blow from the top to the bottom of the chassis 1, forming effective air convection with the design of the ventilation holes 12, which accelerates the discharge of heat inside the chassis 1 and further improves the heat dissipation performance. This structural design also helps to reduce dust accumulation inside the chassis 1, because cold air enters from the bottom, and after passing through the inside of the chassis 1, hot air and dust are more easily discharged by the fan 4 on the top, thereby maintaining the cleanliness and heat dissipation efficiency of the inside of the chassis 1. At the same time, the air can be sent into the water cooling box 2 through the ventilation hole 11, and the water pipes connected to the first water pipe port 31 and the second water pipe port 32 are cooled by air, thereby improving the heat dissipation efficiency. This comprehensive heat dissipation design not only improves the operating stability and reliability of the inverter, but also extends its service life and reduces maintenance costs.

[0026] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any skilled person in the art can make minor changes or modifications to the disclosed technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiments based on the technical essence of the present application still belong to the scope of the technical solution of the present application.
