Description

Technical Field

[0001] This utility model relates to the field of load technology, specifically to a water-cooled load that prevents scale buildup. Background Technology

[0002] With the development of power electronics, the requirements for equipment integration are becoming increasingly stringent. For load devices, the demand is for higher power density and smaller size, a problem that water-cooled loads can effectively address. Water-cooled loads, using water as the cooling medium, offer rapid cooling, excellent heat dissipation, and a power density far exceeding that of air-cooled loads, leading to their widespread application. However, due to the high cost of pure water, it's difficult to achieve large-flow pure water circulation. Therefore, high-power water-cooled loads typically use tap water as the cooling water, which is the most common and economical option. However, using tap water presents a significant problem: scale buildup. Over time, this scale accumulates, and if not cleaned regularly, it weakens the heat dissipation of the resistors, potentially causing them to burn out or even crack, severely shortening the lifespan of the water-cooled load. Furthermore, in existing water-cooled load structures, uneven heating of the resistors can occur due to flow channel issues, further impacting their lifespan. Summary of the Invention

[0003] In view of the above-mentioned technical problems, the present invention provides a water-cooled load that prevents scale buildup.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A water-cooled load that prevents scale buildup is provided, comprising a cylinder and multiple resistance tubes. The cylinder includes a body and a cover that together form a cavity for holding cooling water. A partition plate is provided in the cavity to divide the cavity into an upper chamber and a lower chamber. Multiple resistance tubes are fixed side by side to the cover and inserted into the upper chamber. The resistance core of the resistance tubes is insulated from the cooling water in the upper chamber.

[0006] The lower chamber is connected to a water inlet pipe, which is equipped with a water inlet valve.

[0007] The upper chamber and the lower chamber are connected by a transition pipe, which is equipped with an intermediate valve.

[0008] The upper chamber is connected to a water outlet pipe, which is equipped with a water outlet valve.

[0009] The upper chamber is also equipped with a cleaning tube that connects to the lower chamber, and the side wall of the cleaning tube has multiple cleaning holes facing the resistor tube.

[0010] A drain pipe is installed at the lower part of the upper chamber, and the drain pipe is equipped with a drain valve.

[0011] Specifically, the transition pipe connects to the lower part of the lower chamber, and the outlet pipe connects to the upper part of the upper chamber.

[0012] Specifically, the cylinder is cylindrical, with multiple resistance tubes parallel to the axis of the cylinder, and multiple cleaning tubes arranged in parallel with multiple resistance tubes.

[0013] Specifically, heat-conducting fins are installed on the outside of the cleaning pipe.

[0014] Specifically, multiple cleaning holes are distributed in a straight line or spiral along the length of the cleaning tube.

[0015] Specifically, the inlet and outlet pipes are connected to the outer water tank via a water pump, thus forming a circulation loop of water tank-water pump-inlet pipe-lower chamber-transition pipe-upper chamber-outlet pipe-water tank.

[0016] Specifically, a temperature sensor is pre-embedded inside the resistance tube. The temperature sensor, inlet valve, outlet valve, intermediate valve, drain valve, and water pump are all connected to the external controller.

[0017] Specifically, the partition is arranged at an angle relative to the horizontal direction, and the drain pipe is connected to the lower part of the upper chamber.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a water-cooled load to prevent scale buildup. When cooling the resistance tube is required, the inlet valve, intermediate valve, and outlet valve are opened, while the drain valve is closed. Cooling water enters the lower chamber through the inlet pipe and simultaneously passes through the transition pipe and cleaning pipe into the upper chamber, immersing the resistance tube in the cooling water. The liquid sprayed from the cleaning hole of the cleaning pipe enhances the fluidity of the cooling water and washes the surface of the resistance tube, making the internal heat exchange of the cooling water more thorough and enhancing the cooling effect. It also accelerates the heat exchange in some dead corners of the flow channel, making the heat dissipation of the resistance tube more uniform and improving the stability and service life of the heating element.

[0020] When scale needs to be cleaned, the intermediate valve and outlet valve are closed, while the inlet valve and drain valve are opened. Water in the upper chamber is discharged from the drain pipe, and cooling water enters the lower chamber through the inlet pipe. The cooling water is then sprayed onto the resistor tube through the cleaning pipe. This allows the resistor tube inside the cylinder to be cleaned without disassembling the resistor, preventing scale buildup on the surface of the resistor tube from affecting its lifespan.

[0021] In summary, this load can ensure uniform cooling and heat dissipation, extend the lifespan of the resistor, and also has a scale cleaning function, which can periodically clean scale, thereby improving the stability and lifespan of the water-cooled load. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] This embodiment describes a water-cooled load designed to prevent scale buildup, such as... Figures 1 to 3 As shown, the device includes a cylindrical body 1 and multiple resistance tubes 2. The cylindrical body 1 includes a cylindrical body 11 and a cylindrical cover 12 that together form a receiving cavity for holding cooling water. A partition plate 13 is provided in the receiving cavity, thereby dividing the receiving cavity into an upper chamber 14 and a lower chamber 15. The multiple resistance tubes 2 are fixed side by side to the cylindrical cover 12 and inserted into the upper chamber 14. Each resistance tube 2 includes a metal tube and a resistance core located inside the metal tube. The metal tube is filled with insulating powder, thereby insulating the resistance core from the metal tube and, consequently, from the cooling water in the upper chamber 14.

[0035] The lower chamber 15 is connected to a water inlet pipe 3, which is equipped with an inlet valve 31. The upper chamber 14 and the lower chamber 15 are connected via a transition pipe 4, which is equipped with an intermediate valve 41. The upper chamber 14 is connected to a water outlet pipe 5, which is equipped with an outlet valve 51. A cleaning pipe 6, connecting to the lower chamber 15, is also located within the upper chamber 14. The side wall of the cleaning pipe 6 has multiple cleaning holes 61 facing the resistance tube 2. A drain pipe 7, equipped with a drain valve 71, is located at the lower part of the upper chamber 14. All these valves are electric valves.

[0036] When the resistance tube 2 needs to be cooled, the inlet valve 31, intermediate valve 41, and outlet valve 51 are opened, and the drain valve 71 is closed. Cooling water enters the lower chamber 15 from the inlet pipe 3, and simultaneously enters the upper chamber 14 through the transition pipe 4 and the cleaning pipe 6, immersing the resistance tube 2 in the cooling water. The liquid sprayed from the cleaning hole 61 of the cleaning pipe 6 enhances the fluidity of the cooling water and washes the surface of the resistance tube 2, making the internal cooling water heat exchange more complete and enhancing the cooling effect. At the same time, it also accelerates the water heat exchange in some dead corners of the flow channel, making the heat dissipation of the resistance tube 2 more uniform and improving the stability and service life of the heating tube.

[0037] When scale needs to be cleaned, the intermediate valve 41 and the outlet valve 51 are closed, and the inlet valve 31 and the drain valve 71 are opened. The water in the upper chamber 14 is discharged from the drain pipe 7, and the cooling water enters the lower chamber 15 from the inlet pipe 3. It is sprayed through the cleaning pipe 6 onto the resistor tube 2. The resistor tube 2 inside the cylinder 1 can be cleaned without disassembling the resistor, preventing scale buildup on the surface of the resistor tube 2 from affecting its lifespan.

[0038] In summary, this load can ensure uniform cooling and heat dissipation, extend the lifespan of the resistor, and also has a scale cleaning function, which can periodically clean scale, thereby improving the stability and lifespan of the water-cooled load.

[0039] Specifically, the transition pipe 4 connects to the lower part of the lower chamber 15, and the outlet pipe 5 connects to the upper part of the upper chamber 14.

[0040] Specifically, the cylinder 1 is cylindrical, multiple resistance tubes 2 are parallel to the axis of the cylinder 1, and multiple cleaning tubes 6 are arranged in parallel with the multiple resistance tubes 2.

[0041] Specifically, heat-conducting fins 62 are provided on the outside of the cleaning pipe 6.

[0042] Specifically, multiple cleaning holes 61 are distributed in a straight line or spiral along the length of the cleaning tube 6.

[0043] Specifically, the inlet pipe 3 and the outlet pipe 5 are connected to the outer water tank via a water pump, thus forming a circulation loop of water tank-water pump-inlet pipe 3-lower chamber 15-transition pipe 4-upper chamber 14-outlet pipe 5-water tank.

[0044] Specifically, a temperature sensor is pre-embedded inside the resistance tube 2. The temperature sensor, inlet valve 31, outlet valve 51, intermediate valve 41, and drain valve 71 are all connected to the external controller along with the water pump. When scale builds up on the surface of the resistance tube 2, its heat dissipation performance deteriorates, the internal temperature of the resistance tube 2 rises, and an alarm signal is issued to remind the user to clean the scale and impurities, or to automatically open and close the corresponding valve for automatic cleaning.

[0045] In practice, it can be further modified so that the partition plate 13 is arranged at an angle relative to the horizontal direction, and the sewage pipe 7 is connected to the low position at the bottom of the upper chamber 14.
