Description

Technical Field

[0001] This invention relates to a water-cooling system for frequency converters, belonging to the technical field of water-cooling equipment for frequency converters. Background Technology

[0002] As a core device in power control, frequency converters generate a significant amount of heat during operation. Inadequate heat dissipation can directly lead to overheating, performance degradation, and even damage to internal electronic components, severely impacting their reliability and lifespan. Therefore, an efficient heat dissipation system is crucial for ensuring the stable operation of high-power frequency converters. Currently, the main heat dissipation methods for frequency converters include air cooling, self-cooling, and the increasingly popular water cooling. Water cooling, with its high specific heat capacity and strong thermal conductivity, has become the preferred solution for high-power, high-density frequency converters.

[0003] Patent No. CN202759368U describes a water-cooled frequency converter system. It involves installing a water pipe above the vertical heat dissipation fins, allowing cooling water to flow out from the pipe opening and be guided along a baffle to the top of the fins. The water flows down the fin surface under gravity, carrying away heat through evaporation and convection. However, relying on a single outlet and baffle for water distribution makes it difficult to form a uniform and complete water film on the relatively wide top of the fins. This easily leads to concentrated water flow in some areas while other areas remain dry, resulting in uneven heat dissipation. Furthermore, the free-falling water into the storage tank can cause splashing, potentially intruding into nearby electrical equipment and causing short circuits, leaks, and other safety accidents. Therefore, a water-cooled frequency converter system is urgently needed to solve these problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a water-cooling system for frequency converters, thereby solving the problems mentioned in the background section. The present invention achieves uniform distribution of water flow on the heat dissipation fins by setting the water flow mode to a multi-hole dripping method, thus improving heat dissipation efficiency. The semi-enclosed flow guide can stably guide the cooling water to the bottom of the water tank, preventing splashing when the water flows freely into the water tank, thus enhancing safety and practicality.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a frequency converter water cooling system, comprising a frequency converter, a water collection pipe, a water storage tank, and a sloping guide shell. Multiple heat dissipation fins are fixed to the front side of the frequency converter. Multiple connecting pipes are installed below the water collection pipe. Rectangular shells are respectively installed below the multiple connecting pipes. Multiple drip pipes are connected and installed below the rectangular shells. Magnetic frames are fixed to both sides of the water storage tank. Right-angled rods are fixed to both sides of the sloping guide shell. Iron square frames are respectively fixedly sleeved on the outer sides of the vertical sections of the two right-angled rods. A pumping pipe is connected and installed below the water storage tank. A pumping pump is installed at the upper end of the pumping pipe, and a water delivery pipe is installed at the output end of the pumping pump.

[0006] Furthermore, an inlet pipe is installed at the upper middle part of the water collection pipe, and the inlet pipe and multiple connecting pipes are respectively connected to the inner cavity of the water collection pipe.

[0007] Furthermore, an extended guide shell is connected and installed at the left end of the inclined guide shell.

[0008] Furthermore, support columns are fixed at the four corners below the water storage tank.

[0009] Furthermore, the water supply pipe is sealed to the water inlet pipe.

[0010] Furthermore, each of the aforementioned heat dissipation fins is rhomboid in shape.

[0011] The beneficial effects of this invention are as follows: This invention provides a water-cooling system for a frequency converter. By adding a frequency converter, heat dissipation fins, a water collection pipe, a water delivery pipe, a water pump, a water pumping pipe, a water storage tank, a sloped guide shell, an extended guide shell, a right-angle plug, a rectangular shell, a drip pipe, an iron frame, a support column, a connecting pipe, a water inlet pipe, and a magnetic frame, our design improvements and practical use have shown that this device, by setting the water flow to a multi-hole drip pattern, achieves uniform distribution of water flow on the heat dissipation fins, improving heat dissipation efficiency. The semi-enclosed guide shell stably guides the cooling water to the bottom of the water storage tank, preventing splashing when water falls freely into the tank, thus enhancing safety and practicality.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-5 This invention provides a technical solution: a water-cooling system for a frequency converter, comprising a frequency converter 1, a water collection pipe 3, a water storage tank 7, and a sloping guide shell 8. Multiple heat dissipation fins 2 are fixed to the front of the frequency converter 1. Multiple connecting pipes 15 are installed below the water collection pipe 3. Rectangular shells 11 are respectively installed below the multiple connecting pipes 15. Multiple drip pipes 12 are connected and installed below the rectangular shells 11. Magnetic frames 17 are fixed to both sides of the water storage tank 7. Right-angled inserts 10 are respectively fixed to both sides of the sloping guide shell 8. Sleeves are respectively fixed to the outer sides of the vertical sections of the two right-angled inserts 10. The device is connected to an iron square frame 13. A water pump 5 is installed below the water storage tank 7. A water delivery pipe 4 is installed at the output end of the water pump 5. This design solves the problem that the original device relied on a single water outlet and a baffle for water distribution. The water flow was difficult to form a uniform and complete water film on the top of the wide heat dissipation fins, which easily led to dense water flow in some areas of the fins and dry water in other areas, resulting in uneven heat dissipation. At the same time, the water flow falling freely into the water storage tank was prone to splashing, which may intrude into nearby electrical equipment and cause safety accidents such as short circuits and leakage.

[0016] As the first embodiment of the present invention: a water inlet pipe 16 is installed in the middle of the upper part of the water collection pipe 3. The water inlet pipe 16 and a plurality of connecting pipes 15 are respectively connected to the inner cavity of the water collection pipe 3. The water inlet pipe 16 is set to facilitate the smooth flow of water into the water collection pipe 3, and the connecting pipes 15 are set to facilitate the flow of water into a plurality of rectangular shells 11.

[0017] An extended guide shell 9 is connected to the left end of the inclined guide shell 8. The extended guide shell 9 can stably guide the water flow to the bottom of the water storage tank 7, avoiding water splashing. Support columns 14 are fixed at each of the four corners below the water storage tank 7. The installation of the support columns 14 allows for sufficient space between the water storage tank 7 and the ground, facilitating the installation of the water pump pipe 7. The water supply pipe 4 is sealed to the inlet pipe 16. The multiple heat dissipation fins 2 are diamond-shaped; their special edges and bevels help guide the water flow to spread more evenly.

[0018] As a second embodiment of the present invention: When using the water cooling system of this frequency converter, first, the device is positioned, and then two right-angled plugs 10 are inserted into two magnetic frames 17, so that the two iron square frames 13 are respectively attracted by the two magnetic frames 17, thereby stabilizing the position of the inclined guide shell 8. At this time, multiple heat dissipation fins 2 are covered by the inclined guide shell 8. Then, ensure that the cooling water in the water tank 7 is sufficient. Then, start the water pump 5. The water pump 5 draws the cooling water from the bottom of the water tank 7 through the water pumping pipe 6 and pumps it to the inlet pipe 16 above the water collection pipe 3 through the water delivery pipe 4. After the cooling water flows into the inner cavity of the water collection pipe 3 through the inlet pipe 16 for pressure equalization and distribution, it flows into the corresponding rectangular shell 11 through multiple connecting pipes 15. Under the action of gravity, the water in each rectangular shell 11 drips evenly from multiple drip pipes 12 connected below it, accurately covering the top of the corresponding diamond-shaped heat dissipation fins 2 below. Water flows along the surface of the heat dissipation fins 2, diffuses, flows down, and evaporates to absorb heat, achieving efficient cooling of the frequency converter 1. Unevaporated residual water flowing to the bottom of the heat dissipation fins 2, as well as any splashing water droplets, are effectively intercepted and collected by the inclined guide shell 8 installed at the front and its extended guide shell 9 at the left end. Guided by the inclined guide shell 8, this water flows smoothly back to the water storage tank 7 below, thus completing a closed cooling water cycle.
