Description

Technical Field

[0001] This invention relates to the field of resistor technology, and more specifically to a liquid-cooled load resistor device for data centers. Background Technology

[0002] Existing water-cooled resistors have a water flow channel inside a housing made of insulating material. The resistance wire is placed in the water flow channel. During operation, the cooling water flowing in the water flow channel carries away the heat from the resistance wire to achieve the purpose of cooling down.

[0003] As disclosed in Chinese Patent Document CN103050203B, an integrated water-cooled damping resistor for an ultra-high voltage direct current converter valve is described. This damping resistor is a damping element made of insulating material with an internal channel. The damping element includes a resistance wire with corrosion-resistant input and output ends, positioned on the axis of the channel. A drain port is located at the bottom of the damping element. The resistance wire in the damping resistor is in direct contact with the cooling water, forcing water circulation to achieve a rapid cooling effect.

[0004] For example, Chinese patent document CN103680778B discloses a water-cooled resistor for a frequency converter cabinet and its manufacturing method. The water-cooled resistor includes an insulator with an internal channel and an insulating cover, a resistance strip disposed in the channel of the insulator, and lead terminals connected to both ends of the resistance strip. The insulator is also provided with two water inlets. The resistance strip includes a resistance strip body and multiple protrusions. The resistance strip body and the protrusions are integral. The adjacent protrusions on each side of the resistance strip body are staggered and arranged in opposite directions on the resistance strip body. The resistance strip body is vertically engaged at the central axis position of the channel of the insulator by contacting the two side walls inside the channel of the insulator with the multiple protrusions.

[0005] In existing technologies, to prevent short circuits between the resistor strip and the cooling water, an insulating layer is often plated on the surface of the resistor strip to block it, which affects the efficiency of heat transfer from the resistor strip to the cooling water. Furthermore, the existing water-cooled resistor dynamic structure is complex, increasing manufacturing costs. Summary of the Invention

[0006] In view of the above-mentioned technical problems, the present invention provides a data center liquid-cooled load resistor device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A data center liquid-cooled load resistor device is provided, including an insulating plate and a metal plate stacked on top of each other.

The two ends of the third water-cooling channel are connected to an external water source to circulate cooling water within it; The third water-cooling channel is equipped with a first turbine blade, and the first water-cooling channel is equipped with a second turbine blade. The first turbine blade and the second turbine blade are connected by a connecting shaft so that the water in the third water-cooling channel drives the first turbine blade and the second turbine blade to rotate, and the second turbine blade drives the deionized water in the inner circulation channel to circulate.

[0008] Specifically, the metal plate is provided with a first water storage tank, one end of the third water cooling channel is connected to the first water storage tank, and the first turbine blade is installed in the first water storage tank; the insulating plate is provided with a second water storage tank, one end of the first water cooling channel is connected to the second water storage tank, and the second turbine blade is installed in the second water storage tank.

The resistor strip is in direct contact with insulating deionized water, resulting in good heat dissipation performance and high power density. It adopts an internal and external coolant circulation mode.

In addition, the internal circulation coolant utilizes the flow of the external circulation liquid and is circulated through a dual-turbine structure, eliminating the need for external power supply. The structure is simple and the cost is low. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] This embodiment provides a data center liquid-cooled load resistor device, such as... Figures 1 to 4 As shown, it includes an insulating plate 1 and a metal plate 2 stacked on top of each other. The insulating plate 1 is provided with a vortex-shaped first water cooling channel 11. The first water cooling channel 11 is arranged with a vortex-shaped metal resistance band 3. The two ends of the resistance band 3 are provided with lead-out terminals 31 that extend out of the insulating plate 1.

[0026] The metal plate 2 has two parallel, double-vortex-shaped second water-cooling channels 21 and 22. The second water-cooling channel 21 is connected end-to-end to the first water-cooling channel 11, forming an internal circulation channel filled with electrically insulating deionized water. Specifically, the central port of the first water-cooling channel 11 is connected to the central port of the second water-cooling channel 21 through a through-hole, and the outer peripheral port of the first water-cooling channel 11 is connected to the outer peripheral port of the second water-cooling channel 21 through a through-hole, forming a closed loop. The deionized water does not completely fill the channel, leaving space for flow.

[0027] The two ends of the third water-cooling channel 22 are connected to an external water source to circulate cooling water within it. The third water-cooling channel 22 is equipped with a first turbine blade 4, and the first water-cooling channel 11 is equipped with a second turbine blade 5. The first turbine blade 4 and the second turbine blade 5 are connected on the same shaft via a connecting shaft, so that the water in the third water-cooling channel 22 drives the first turbine blade 4 and the second turbine blade 5 to rotate synchronously. The second turbine blade 5 drives the deionized water in the internal circulating water channel to circulate.

[0028] Specifically, the metal plate 2 has a first water storage tank 23, one end of the third water-cooling channel 22 is connected to the first water storage tank 23, and the first turbine blade 4 is installed in the first water storage tank 23; the insulating plate 1 has a second water storage tank 12, one end of the first water-cooling channel 11 is connected to the second water storage tank 12, and the second turbine blade 5 is installed in the second water storage tank 12. The metal plate 2 has an inlet hole 24 that penetrates the first water storage tank 23 and an outlet hole 25 that penetrates the other end of the second water-cooling channel 21. Water entering through the inlet hole 24 impacts the first turbine blade 4, then enters the third water-cooling channel 22, and finally flows out from the outlet hole 25. The incoming water drives the first turbine blade 4 to rotate, and at the same time drives the second turbine blade 5 to rotate, thereby driving the deionized water to flow in the internal circulation channel.

[0029] Specifically, the insulating plate 1 includes a first plate body 13 and a first cover plate 14. The side of the first plate body 13 has a vortex-shaped first groove, and the first cover plate 14 is attached to the side of the first plate body 13, thereby enclosing the first groove to form the first water cooling channel 11.

[0030] Specifically, the first groove is located on the side of the first plate body 13 opposite to the metal plate 2.

[0031] Specifically, the lead-out terminal 31 of the metal strip extends through the first cover plate 14 in a sealed manner.

[0032] Specifically, the metal plate 2 includes a second plate body 26 and a second cover plate 27. The side of the second plate body 26 has two second grooves in a double-vortex shape. The second cover plate 27 is attached to the side of the second plate body 26, thereby forming the second grooves into the second water-cooling channel 21 and the third water-cooling channel 22.

[0033] Specifically, the second groove is located on the side of the second plate body 26 opposite to the insulating plate 1.

[0034] Specifically, the water flow direction of the second water-cooling channel 21 is opposite to that of the third water-cooling channel 22, so that the coolant at each position reaches the maximum temperature difference, resulting in faster heat dissipation and improved heat dissipation efficiency.

[0035] Specifically, insulating board 1 is a mica board, and metal board 2 is a stainless steel board or an aluminum board.

[0036] During manufacturing: 1) First, create a vortex-shaped groove on an insulating board made of electrical insulating material, and then install the vortex-shaped resistor strip into the groove; 2) Construct a small water storage tank at the head of the vortex channel, and install a turbine blade inside the tank to drive water circulation. 3) On the metal plate, a double vortex groove is made. One groove is used to form a circulation loop with the groove on the insulating plate, and the other groove is used for the flow of external cooling water. 4) At the head of the tank that connects to the outside, a water storage tank is constructed for mounting turbine blades. This turbine is coaxial with the previous turbine. When the external cooling water flows, it drives this turbine to rotate, simultaneously driving the other turbine to rotate, thereby causing the internal circulating water to flow. This achieves the final resistance cooling by using the external circulating water to cool the internal circulating water.

[0037] The main innovation of this patent is that the externally circulating water drives a turbine, which in turn drives the internally circulating water for resistor cooling. This allows the internal circulation to use deionized water, while the externally circulating coolant can be of various types and doesn't necessarily need to be non-conductive. Ordinary tap water cools the deionized water, which in turn cools the resistor. Furthermore, it's all within a single module; the power for the internal circulation is transmitted from the external circulation via the turbine, eliminating the need for additional power to the internal circulation.
