Description

Technical Field

[0001] The 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 requirements for the integration of equipment are getting higher and higher. For load equipment, the power density is required to be higher and higher, and the volume is getting smaller and smaller. Water-cooled load can solve this problem well. Because water-cooled load uses water as the cooling medium, the cooling speed is fast, the heat dissipation performance is good, and the power density is much greater than that of air-cooled load, so water-cooled load is more and more widely used. Due to the high cost of pure water, it is difficult to achieve a large flow of pure water as cooling circulating water. Therefore, high-power water-cooled loads usually use tap water as cooling water. Tap water is the most commonly used and economical cooling water. However, there is a difficult problem to solve when using tap water as cooling water. Scale will be generated during use. Long-term use will cause more and more scale. If it is not cleaned for a long time, the heat dissipation of the resistor tube will be weakened, causing the resistor tube to burn out, and even serious accidents such as cracked tubes will occur, which greatly shortens the service life of the water-cooled load. In addition, in the existing water-cooled load structure, the resistor tube will be heated unevenly due to the problem of the flow channel, affecting the life of the resistor.

[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 water cooling load with high heat exchange efficiency in this embodiment, such as Figures 1 to 5 As shown, it includes a cylinder 1 and a plurality of resistor tubes 2. The cylinder 1 includes 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 to divide the receiving chamber into an upper chamber 14 and a lower chamber 15. The plurality of resistor tubes 2 are fixed to the cylinder cover 12 in parallel and inserted into the upper chamber 14. The resistor tube 2 includes a metal tube and a resistor core located in the metal tube. The metal tube is filled with insulating powder, so that the resistor core is insulated and separated from the metal tube, and further the resistor core is insulated and separated from the cooling water in the upper chamber 14.

[0042] The lower chamber 15 is connected to the water inlet pipe 3, and the water inlet pipe 3 is provided with a water inlet valve 31. The upper chamber 14 and the lower chamber 15 are connected via a transition pipe 4, and the transition pipe 4 is provided with an intermediate valve 41. The upper chamber 14 is connected to the water outlet pipe 5, and the water outlet pipe 5 is provided with a water outlet valve 51. The lower chamber 15 is provided with a rotatable water turbine 8 via a bearing, and the lower chamber 15 is also connected to a continuous flow pipe 9, and the continuous flow pipe 9 is provided with a normally closed continuous flow valve 91. After flowing from the water inlet pipe 3 into the lower chamber 15, the cooling water flowing 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 is also provided with a cleaning pipe 6 connected to the lower chamber 15. The lower end of the cleaning pipe 6 is connected to the rotation center of the water turbine 8. The cleaning pipe 6 is connected to a stirring pipe 63 that deviates from the rotation center. The stirring pipe 63 is staggered with the resistor tube 2, and the layout of the resistor tube 2 is staggered from the rotation track of the stirring pipe 63. The upper chamber 14 leaves a space for the stirring pipe 63 to rotate. The side walls of the stirring pipe 63 and the cleaning pipe 6 are provided with a plurality of cleaning holes 61 facing the resistor tube 2. A sewage pipe 7 is provided at the lower part of the upper chamber 14, and the sewage pipe 7 is provided with a sewage valve 71. These valves are all electric valves.

[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 placement space 17. The cleaning tube 6 is connected to a manifold 64 located in the tube placement space 17 and arranged radially along the cylinder body 1, and a plurality of stirring tubes 63 are connected to the manifold 64 at intervals. The plurality of resistor tubes 2 are distributed in a plurality of concentric circular tracks, and the clearance space 16 is formed between two adjacent circles of resistor tubes 2 and between the inner wall of the cylinder body 11 and the resistor tube 2. When the resistor tube 2 needs to be cooled, the water inlet valve 31, the middle valve 41, and the water outlet valve 51 are opened, and the continuous flow valve 91 and the sewage valve 71 are closed. 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, so that the internal cooling water heat exchange is more sufficient, thereby enhancing the cooling effect of the cooling water. At the same time, the water heat exchange in some dead corners of the flow channel is accelerated, so that the heat dissipation of the resistor tube 2 is more uniform, thereby 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 inlet valve 31, the drain valve 71 and the follow-up valve 91 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, and is sprayed on 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 scale on the surface of the resistor tube 2 from accumulating and affecting the life of the resistor tube 2. The function of the follow-up pipe 9 is that after closing the transition pipe 4, the water flow in the lower chamber 15 can still drive the water turbine 8 to rotate. The diameter of the follow-up 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 plurality of resistance tubes 2 are parallel to the axis of the cylinder 1 , and the stirring tube 63 , the cleaning tube 6 and the plurality of resistance tubes 2 are arranged in parallel.

[0049] Specifically, heat conducting fins 62 are provided on the outer side 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 length 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 in the resistor tube 2, and the temperature sensor, the water inlet valve 31, the water outlet valve 51, the intermediate valve 41, the sewage valve 71 and the water pump are connected to the peripheral controller. When the surface of the resistor tube 2 is full of scale, the heat dissipation performance of the resistor tube 2 deteriorates, and the temperature inside the resistor tube 2 rises, giving an alarm signal to remind that the scale impurities need to be cleaned, or the corresponding valve is automatically switched for automatic 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 resistor 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] A lot of 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, and the water is ejected from the cleaning hole 61, impacting the surface wall of the resistor tube 2, knocking the scale on the surface wall 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.
