Description

Technical Field

[0001] The present invention relates to the technical field of loads, and in particular to an agitated water-cooled load with high heat exchange efficiency. Background Art

[0002] With the development of power electronics, the demand for device integration is becoming increasingly demanding. Load devices are required to have ever-increasing power density and ever-smaller size. Water-cooled loads are an excellent solution to this problem. Because they use water as a cooling medium, water-cooled loads offer rapid cooling, excellent heat dissipation, and a power density far greater than that of air-cooled loads. Consequently, they are becoming increasingly popular. Due to the high cost of pure water, it is difficult to achieve high flow rates for circulating cooling water. Therefore, high-power water-cooled loads typically use tap water as the cooling water, which is the most common and economical cooling water. However, using tap water as cooling water presents a significant challenge: scale buildup during use. Over time, this scale buildup accumulates. If left untouched, this can weaken the heat dissipation of resistor tubes, leading to burnout and even serious accidents like cracking. This significantly shortens the service life of the water-cooled load. Furthermore, existing water-cooled load structures can suffer from uneven heating of the resistor tubes due to flow path issues, impacting the lifespan of the resistors. Summary of the Invention

[0005] Provided is a stirring-type water-cooled load with high heat exchange efficiency, comprising a cylinder and a plurality of resistance tubes. The cylinder comprises a cylinder body and a cylinder cover, which together form a receiving chamber for holding cooling water. A partition plate is provided in the receiving chamber, thereby dividing the receiving chamber into an upper chamber and a lower chamber. The plurality of resistance tubes are fixed in parallel to the cylinder cover and inserted into the upper chamber. The resistance cores of the resistance tubes are insulated and separated from the cooling water in the upper chamber.

[0009] The lower chamber is also connected to a continuous flow pipe, which is equipped with a normally closed continuous flow valve. The cooling water flowing from the water inlet pipe into the lower chamber and out of the transition pipe / continuous flow pipe can drive the water turbine to rotate.

[0010] The upper chamber is also provided with a cleaning pipe connected to the lower chamber. The lower end of the cleaning pipe is connected to the rotation center of the water turbine. The cleaning pipe is connected to a stirring pipe that is offset from the rotation center. The stirring pipe and the resistance tube are staggered. The upper chamber leaves space for the stirring pipe to rotate. The side walls of the stirring pipe and the cleaning pipe are provided with multiple cleaning holes facing the resistance tube.

[0012] Specifically, the transition pipe is connected to the lower part of the lower chamber, and the water outlet pipe is connected to the upper part of the upper chamber.

[0013] Specifically, the multiple resistance tubes are parallel to the axis of the cylinder, and the stirring tube, the cleaning tube and the multiple resistance tubes are arranged in parallel.

[0014] Specifically, there is a distance between the lower end of the resistance tube and the bottom of the upper chamber, thereby leaving space for the tube. The cleaning tube is connected to a manifold located in the tube space and arranged radially along the cylinder, and multiple stirring tubes are connected to the manifold at intervals.

[0015] The plurality of resistor tubes are distributed in a plurality of concentric circular tracks, and the clearance space is formed between two adjacent circles of resistor tubes and between the inner wall of the cylinder body and the resistor tubes.

[0017] Specifically, heat-conducting fins are provided on the outsides of the cleaning tube and the stirring tube.

[0018] Specifically, the plurality of cleaning holes are distributed along a straight line or a spiral line in the length direction of the cleaning pipe.

[0019] Specifically, the water inlet pipe and the water outlet pipe are connected to the peripheral water tank via a water pump, thereby forming a circulation loop of water tank-water pump-water inlet pipe-lower chamber-transition pipe-upper chamber-water outlet pipe-water tank.

[0020] Specifically, a temperature sensor is embedded in the resistance tube, and the temperature sensor, the water inlet valve, the water outlet valve, the intermediate valve, the sewage valve and the water pump are connected to the peripheral controller.

[0021] Beneficial effects of the present invention:

[0022] The present invention provides an agitated water-cooled load with high heat exchange efficiency. When the resistor tube needs to be cooled, the water inlet valve, the intermediate valve, and the water outlet valve are opened, and the continuous flow valve and the sewage valve are closed. The cooling water enters the lower chamber from the water inlet pipe, and enters the upper chamber through the transition pipe, the agitation pipe, and the cleaning pipe, so that the resistor tube is immersed in the cooling water. The liquid sprayed from the cleaning holes of the cleaning pipe and the agitation pipe enhances the fluidity of the cooling water and flushes the surface of the resistor tube, making the internal cooling water heat exchange more sufficient and enhancing the cooling effect of the cooling water. 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 resistor tube more uniform, and improving the stability and service life of the electric heating tube.

[0023] When scale needs to be cleaned, the middle valve and the water outlet valve are closed, the water inlet valve and the sewage valve are opened, the water in the upper chamber is discharged from the sewage pipe, and the cooling water enters the lower chamber from the water inlet pipe and is sprayed onto the resistor tube through the cleaning pipe. The resistor tube in the cylinder can be cleaned without disassembling the resistor to prevent scale accumulation on the surface of the resistor tube and affect the life of the resistor tube.

[0024] In summary, this load can make the cooling and heat dissipation uniform and increase the service life of the resistor. At the same time, it has a scale cleaning function, which can clean the scale regularly and improve the stability and life of the water-cooled load. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] A stirring type water cooling load with high heat exchange efficiency in this embodiment, such as Figures 1 to 5 As shown, the device comprises a cylinder 1 and a plurality of resistance tubes 2. The cylinder 1 comprises a cylinder body 11 and a cylinder cover 12, which together form a receiving chamber for holding cooling water. A partition plate 13 is provided in the receiving chamber, thereby dividing the receiving chamber into an upper chamber 14 and a lower chamber 15. The plurality of resistance tubes 2 are fixed in parallel to the cylinder cover 12 and inserted into the upper chamber 14. The resistance tubes 2 comprise a metal tube and a resistance core located within the metal tube. The metal tube is filled with insulating powder, thereby isolating the resistance core from the metal tube, and further isolating the resistance core from the cooling water in the upper chamber 14.

[0042] The lower chamber 15 is connected to the water inlet pipe 3, which is provided with a water inlet valve 31. The upper chamber 14 and the lower chamber 15 are connected via a transition pipe 4, which is provided with an intermediate valve 41. The upper chamber 14 is connected to the water outlet pipe 5, which is provided with a water outlet valve 51. The lower chamber 15 is provided with a rotatable water turbine 8 via a bearing. The lower chamber 15 is also connected to a continuous flow pipe 9, which is provided with a normally closed continuous flow valve 91. The cooling water that flows from the water inlet pipe 3 into the lower chamber 15 and flows out from the transition pipe 4 and / or the continuous flow pipe 9 can drive the water turbine 8 to rotate. One end of the continuous flow pipe 8 is connected to the transition pipe 4, and the other end of the continuous flow pipe 9 is connected to the water outlet pipe 5. The water inlet pipe 3 and the transition pipe 4 are respectively located on the opposite sides of the water turbine 8.

[0043] The upper chamber 14 also houses a cleaning pipe 6, which connects to the lower chamber 15. The lower end of the cleaning pipe 6 is connected to the rotation center of the hydrodynamic turbine 8. The cleaning pipe 6 is connected to a stirring pipe 63, which is offset from the rotation center. The stirring pipe 63 is staggered with the resistor tube 2, and the resistor tube 2 is arranged so that the stirring pipe 63's rotation trajectory is offset. The upper chamber 14 leaves space for the stirring pipe 63 to rotate. The sidewalls of the stirring pipe 63 and the cleaning pipe 6 are provided with multiple cleaning holes 61 facing the resistor tube 2. A drain pipe 7 is located at the bottom of the upper chamber 14, equipped with a drain valve 71. These valves are all electrically operated.

[0044] Specifically, a distance is left between the lower end of the resistor tube 2 and the bottom of the upper chamber 14, thereby leaving a tube space 17. The cleaning tube 6 is connected to a manifold 64 located in the tube space 17 and arranged radially along the barrel 1. Multiple agitation tubes 63 are connected to the manifold 64 at intervals. The multiple resistor tubes 2 are arranged in a plurality of concentric circular paths, with the aforementioned clearance spaces 16 formed between adjacent circles of resistor tubes 2 and between the inner wall of the barrel body 11 and the resistor tubes 2. When the resistor tube 2 needs to be cooled, the water inlet valve 31, the intermediate valve 41, and the water outlet valve 51 are opened, the continuous flow valve 91 and the sewage valve 71 are closed, and the cooling water enters the lower chamber 15 from the water inlet pipe 3, and at the same time enters the upper chamber 14 through the transition pipe 4, the stirring pipe 63 and the cleaning pipe 6, so that the resistor tube 2 is immersed in the cooling water. The liquid sprayed from the cleaning hole 61 of the cleaning pipe 6 and the stirring pipe 63 enhances the fluidity of the cooling water and flushes the surface of the resistor tube 2, making the internal cooling water heat exchange more sufficient, thereby enhancing the cooling effect of the cooling water. 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 resistor tube 2 more uniform, and improving the stability and service life of the electric heating tube.

[0045] When it is necessary to clean the scale, the middle valve 41 and the outlet valve 51 are closed, the water inlet valve 31, the sewage valve 71, and the continuous flow valve 91 are opened, the water in the upper chamber 14 is discharged from the sewage pipe 7, and the cooling water enters the lower chamber 15 from the water inlet pipe 3, and is sprayed onto the resistor tube 2 through the cleaning pipe 6 and the stirring pipe 63. The resistor tube 2 in the cylinder 1 can be cleaned without disassembling the resistor to prevent the accumulation of scale on the surface of the resistor tube 2 and affect the life of the resistor tube 2. The function of the continuous flow pipe 9 is to ensure that after the transition pipe 4 is closed, the water flow in the lower chamber 15 can still drive the water turbine 8 to rotate. The diameter of the continuous flow pipe 9 is smaller than that of the transition pipe 4, so that most of the water enters the cleaning pipe 6 during cleaning.

[0046] In summary, this load can make the cooling and heat dissipation uniform and increase the service life of the resistor. At the same time, it has a scale cleaning function, which can clean the scale regularly and improve the stability and life of the water-cooled load.

[0047] Specifically, the transition pipe 4 is connected to the lower part of the lower chamber 15 , and the water outlet pipe 5 is connected to the upper part of the upper chamber 14 .

[0048] Specifically, the cylinder 1 is cylindrical, the multiple resistance tubes 2 are parallel to the axis of the cylinder 1, and the stirring tube 63, the cleaning tube 6 and the multiple resistance tubes 2 are arranged in parallel.

[0049] Specifically, heat conducting fins 62 are provided on the outside of the cleaning pipe 6 .

[0050] Specifically, the plurality of cleaning holes 61 are distributed along a straight line or a spiral line in the longitudinal direction of the cleaning tube 6 .

[0051] Specifically, the water inlet pipe 3 and the water outlet pipe 5 are connected to the peripheral water tank via a water pump, thereby forming a circulation loop of water tank-water pump-water inlet pipe 3-lower chamber 15-transition pipe 4-upper chamber 14-water outlet pipe 5-water tank.

[0052] Specifically, a temperature sensor is embedded within resistor tube 2. The temperature sensor, water inlet valve 31, water outlet valve 51, intermediate valve 41, drain valve 71, and water pump are all connected to a peripheral controller. When scale accumulates on the surface of resistor tube 2, its heat dissipation performance deteriorates, and the temperature inside the resistor tube rises. This triggers an alarm, prompting the user to clean the scale impurities, or automatically opens and closes the corresponding valve for cleaning.

[0053] Compared with the prior art, a hydraulic turbine 8 is provided at the bottom of the load. During normal use, the hydraulic turbine 8 rotates through the flow of water, driving the cleaning pipe 6 and the stirring pipe 63 above, stirring the water in the upper chamber 14, accelerating the heat exchange between the resistance tube 2 and the cooling water, and also accelerating the heat exchange of the water in the dead corner of the flow in the upper chamber.

[0054] Many cleaning holes 61 are opened on the cleaning pipe 6. When cleaning scale, the middle valve 41 and the water outlet valve 51 are closed, and the sewage valve 71 is opened to ensure that the bottom hydraulic turbine 8 can rotate. Water enters the cleaning pipe 6 through the small hole on the top of the hydraulic turbine 8. The water is ejected from the cleaning hole 61, impacting the surface wall of the resistor tube 2, impacting the scale on the surface wall and falling off, and finally discharged from the bottom sewage pipe 7. At the same time, the scale on the surface of the resistor tube 2 is rotated to clean, so that the scale is cleaned more thoroughly.
