Description

Technical Field

[0001] This utility model relates to a cooling distribution device, and more particularly to one that can effectively prevent the formation of biofilm, inhibit bacterial growth and the formation of bacterial scale, thereby enabling the cooling water to flow smoothly. Background Technology

[0002] The existing cooling system of a computer data processing center is mainly divided into four zones in sequence. Zone 1 is the high-temperature load heat source zone where power consumption continuously increases. Zone 2 is the liquid cooling distribution zone of the cooling distribution unit (CDU). Zone 3 is the cooling zone of plate heat exchangers or chillers. The final zone 4 is the total heat dissipation zone that uses a cooling tower to dissipate all heat. In Zone 1, the data in the server is mainly processed and calculated by multiple central processing units (CPUs). These CPUs are mostly located in close contact with heat sinks such as cold plates, and heat dissipation is achieved through the heat exchange of fluids in the microchannels inside the cold plates. However, because the channels of the microchannels are very narrow, when the cooling water flow in each area cannot flow smoothly, especially the cooling water flow entering the first zone from the cooling distribution device, for example, when the cooling water contains tiny particles, oxides, impurities, or when scale and biofilm grow and block the water flow pipes, the heat conduction capacity of each heat sink will decrease, the overall cooling efficiency will decline, and thus the efficiency of computer operation will be reduced. Utility Model Content

[0003] In view of this, in order to provide a structure that is different from the existing technology and to improve the above-mentioned shortcomings, the inventor has accumulated many years of experience and continuous research and development, resulting in this utility model.

[0004] To achieve the aforementioned objectives, the cooling distribution device of this utility model includes a first heat exchange end and a second heat exchange end. The first heat exchange end has a first cold water end and a first warm water end, which are connected to a heat dissipation device. The first heat exchange end is connected to the second heat exchange end for heat exchange. The second heat exchange end has a second cold water end and a second warm water end, which are connected to a heating device. Its main technical features are: the second cold water end has an outlet pipe, an adapter, an inlet pipe, and an electrode rod. One end of the outlet pipe is connected to the first end of the adapter, the second end of the adapter is connected to the inlet pipe, and one end of the inlet pipe is connected to the heating device. The adapter has an opening, and the electrode rod is inserted into the opening and fixed to the adapter.

[0005] In practice, this utility model also includes a first tapered tube and a second tapered tube. The small-diameter end of the first tapered tube is connected to one end of the outlet pipe, and the large-diameter end of the first tapered tube is connected to the first end of the adapter. The small-diameter end of the second tapered tube is connected to the other end of the inlet pipe, and the large-diameter end of the second tapered tube is connected to the second end of the adapter.

[0006] In practice, the electrode rod includes a ceramic shell and a cable. The ceramic shell is inserted into the opening and housed in the water outlet pipe. One end of the cable is inserted into and fixed inside the ceramic shell, and the other end of the cable is electrically connected to a power supply to provide a high-voltage and low-current DC power input.

[0007] In practice, the electrode rod includes a ceramic shell and a cable. The ceramic shell is inserted into the opening and housed in the water inlet pipe. One end of the cable is inserted into and fixed inside the ceramic shell, and the other end of the cable is electrically connected to a power supply to provide a high-voltage and low-current DC power input.

[0008] The beneficial effects of this utility model are as follows: One objective of this utility model is to provide a cooling distribution device that can solve the problem that the cooling water flow in the existing heat dissipation system cannot flow smoothly in the microchannels inside the cold plate, which reduces the heat conduction capacity, causes the overall cooling efficiency to decline, and thus reduces the computer's operating efficiency. By installing an electrode rod at the bend of the cold water outlet of the cooling distribution device, the formation of biofilm, bacterial growth and bacterial scale are prevented, the cooling water flow is smooth, the heat dissipation capacity is not reduced, and the stable operation of the computer is ensured. It also effectively saves electricity and energy. Attached Figure Description

[0037] A cooling distribution unit (CDU) not only promotes the flow of liquid but also replenishes or recools the coolant. This invention's cooling distribution unit includes a first heat exchange end and a second heat exchange end. The first heat exchange end has a first cold water end and a first warm water end, which are connected to a heat dissipation device. The first heat exchange end is connected to the second heat exchange end for heat exchange. The second heat exchange end has a second cold water end and a second warm water end, which are connected to a heating device. Its main technical features are: the second cold water end has an outlet pipe, an adapter, an inlet pipe, and an electrode rod; one end of the outlet pipe is connected to the first end of the adapter, the second end of the adapter is connected to the inlet pipe, and one end of the inlet pipe is connected to the heating device; the adapter has an opening, and the electrode rod is inserted into the opening and fixed to the adapter. In this way, a high-voltage and low-current DC power supply can be input to a power supply, which effectively prevents the formation of biofilm in the flow channel, inhibits bacterial growth and the formation of bacterial scale, and thus allows the cooling water used for heat dissipation to flow smoothly.

[0038] Please see Figure 1 As shown, this is a preferred embodiment of the cooling distribution device 1 of this utility model, which mainly includes a first heat exchange end 2 and a second heat exchange end 3 connected adjacent to each other for heat exchange. The first heat exchange end 2 has a first cold water end 21 and a first warm water end 22 connected together. One end of the first cold water end 21 is connected to a chiller 23, which is then connected to a cooling tower to input low-temperature water flow. In practice, the cooling tower serves as a heat dissipation device 24. One end of the first warm water end 22 is connected to a first pump 25, which is then connected to the cooling tower to accelerate the return flow of high-temperature water flow and dissipate all the heat of the high-temperature water flow to the outside through the heat dissipation device 24.

[0039] The second heat exchange end 3 includes a second cold water end 31 and a second warm water end 32 connected together. The second cold water end 31 includes an outlet pipe 33, a first tapered pipe 34, an adapter 35, a second tapered pipe 36, an inlet pipe 37, and an electrode rod 38. One end of the outlet pipe 33 is connected to the small-diameter end of the first tapered pipe 34, and the large-diameter end of the first tapered pipe 34 is connected to the first end 351 of the adapter 35, so that the first end 351 with a diameter of 3 cm tapes back and connects to the outlet pipe 33 with a diameter of 2 cm. The adapter 35 is a tee pipe, and the second end 352 of the adapter 35 is connected to the large-diameter end of the second tapered pipe 36, and the small-diameter end of the second tapered pipe 36 is connected to the other end of the inlet pipe 37, so that the second end 352 with a diameter of 3 cm tapes back and connects to the inlet pipe 37 with a diameter of 2 cm. In addition, one end of the water inlet pipe 37 is connected to a heating device 4 so that cold water flows into the heating device 4, and the heat generated by the data processing of multiple servers 41 is carried out through the second warm water end 32. Then, through the pressurization of a second pump 39, the warm water flow is accelerated to the water outlet pipe 33, and the water flow is cooled by heat exchange with the first heat exchange end 2.

[0040] The third end 353 of the adapter 35 has an opening 354; the electrode rod 38 includes a ceramic housing 381 and a cable 382. The elongated ceramic housing 381 is inserted into the opening 354 and accommodated within the outlet pipe 33 and the first tapering pipe 34; one end of the cable 382 is inserted into and fixed inside the ceramic housing 381, while the other end of the cable 382 is electrically connected to a power supply 5 to convert 90 to 240 volts of AC power into 35,000 volts of high-voltage, low-current DC power, which is then input into the ceramic housing 381. In practice, the elongated ceramic housing 381 can also be inserted into the opening 354 and accommodated within the second tapering pipe 36 and the inlet pipe 37.

[0041] Thus, when the power supply 5 inputs a high-voltage, low-current DC power of 35,000 volts into the electrode rod 38, a very high-voltage capacitive field is formed between the ceramic shell 381 and the water pipe wall. This increases the surface charge of the colloidal particles in the water, maintaining them at a high electrostatic repulsion potential. When this electrostatic repulsion potential exceeds the van der Waals force, the colloidal particles disperse and do not aggregate. This allows the particles to remain stably suspended and dispersed, preventing them from easily coagulating and adhering to the pipe surface, thus preventing scale and agglomeration. It also inhibits the growth of bacteria and microorganisms. As a result, scale and biofilm gradually soften and slough off, achieving the effects of preventing biofilm formation, inhibiting bacterial growth, and preventing bacterial scale buildup in the cooling distribution device.

[0042] In summary, based on the above-disclosed content, this utility model can indeed achieve its intended purpose, providing a cooling distribution device that can effectively prevent the formation of biofilm, inhibit bacterial growth and the formation of bacterial scale, ensure smooth cooling water flow and maintain heat dissipation capacity, thereby ensuring stable operation of computer computing, and effectively save electricity and energy costs. It has great industrial application value.

[0043] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Anyone skilled in the art should know that under the technical spirit of this utility model, any easily conceivable variations or modifications are possible and are all covered by the patent application scope of this utility model.
