Description

Technical Field

[0001] The utility model relates to the technical field of power supply equipment, in particular to a water channel structure for water-cooling and heat dissipation of a power supply. Background Art

[0002] A power supply is a device that converts other forms of energy into electrical energy and provides energy to circuits (electronic devices).

[0003] Water cooling is a common way to cool power supplies. It is done by fixing the metal heat dissipation material carrying the heat-generating device on a water-cooled plate. A cooling medium, such as a fluid medium, is arranged inside the water-cooled plate. The cooling medium absorbs heat to achieve cooling and heat dissipation of the power supply device. The fluid medium in the power supply water-cooled plate is usually connected to the internal pipeline of the heat exchanger (such as a condenser) to form a cooling circulation loop to maintain long-term cooling and heat dissipation.

[0004] In the prior art, two water channels are led out from the same side of the heat exchanger and connected to the two water channel ports of the power water cooling plate to form a cooling circulation loop. However, since the pipelines are connected by flow tubes and nylon right-angle joints, the leakage rate during the processing and connection process is as high as 20%-30%. The main reasons for the high leakage rate are as follows:

[0005] The water outlet section at the outlet port of the heat exchanger adopts the method of copper tube sealing and inserting into the right-angle nylon joint. Since the copper tube wall thickness is 0.5-0.6mm, the material is soft and very easy to deform, the deformed copper tube inserted into the nylon tube mouth during the assembly process is easy to damage the internal sealing ring. The copper tube is not round enough, so the internal sealing ring of the nylon joint does not fit well with the outer diameter wall of the copper tube, which is prone to water leakage.

[0006] The outlet port of the heat exchanger adopts copper welding technology. The solder is easy to flow / overflow during the processing, and the surface of the tube body is uneven after shaping, resulting in poor fit between the nylon pipe joint and the outlet port, which is prone to water leakage.

[0007] The installation space at the outlet of the heat exchanger is small, which makes assembly difficult, and the pipe body and the joint are not easily assembled properly when docking;

[0008] Based on the problems in the prior art, the utility model provides a water channel structure for water-cooling and heat dissipation of a power supply. Utility Model Content

[0036] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0037] For ease of understanding, the application scenario of the present application is first explained. During the operation of the power supply device, it is necessary to use a heat dissipation device, such as a water cooling plate, a heat sink or a fan blade structure to dissipate heat from the power supply heating components. Figure 6 , a water-cooled plate is used to cool the power supply equipment, wherein the planes in which the medium pipeline on the water-cooled plate of the power supply and the medium pipeline of the heat exchanger are arranged are perpendicular to each other and need to be connected through a medium flow path to form a cooling circulation loop.

[0038] However, since the medium pipelines of the heat exchanger and the water-cooled plate are arranged in planes that are perpendicular to each other, the water leading out of the heat exchanger needs to be bent and reversed at least once to be guided to the water port of the water-cooled plate to achieve docking. The lead-out ports on the heat exchanger are docked using right-angle nylon connectors, and both lead-out ports are located on the side walls of the heat exchanger. The operating space is small, assembly is difficult, and it is easy to assemble improperly, resulting in water leakage.

[0039] In addition, when the nylon copper tube is welded, the solder flows out of the welding place, resulting in an uneven surface of the tube wall. When the tube mouth is plugged into the connection, it is difficult to insert it into place. The uneven surface also causes the tube body and the tube body and the sealing ring to have insufficient fit, which is prone to water leakage.

[0040] like Figure 1 As shown, a water path structure for water cooling of a power supply is provided, including a flow path connected between a power supply water cooling plate 3 and a heat exchanger 4, wherein the flow path is provided with two independent ones, namely a first medium flow path 1 and a second medium flow path 2, wherein the first medium flow path 1 and the second medium flow path 2 are connected to the heat exchanger 4 and the power supply water cooling plate 3, so as to form a cooling circulation loop between the power supply water cooling plate 3 and the heat exchanger 4 for heat exchange of the power supply water cooling plate 3.

[0041] The plane where the power water cooling plate 3 is located is perpendicular to the plane where the heat sinks on the heat exchanger 4 are extended and arranged. The water inlet port of the heat exchanger 4 is connected to the first medium flow path 1 and the second medium flow path 2 by elbow welding, and a sealing joint is installed on the elbow.

[0042] The heat exchanger 4 uses a curved pipe to lead out the flow path to avoid the flow pipe being bent and stressed, so as to keep the pipe body and the port smoothly connected and prevent water leakage.

[0043] Theoretically, the fluid medium used for heat dissipation in the power water cooling plate 3 can be one of alcohol-type coolant, glycerin-type coolant, ethanol-type coolant, propanol-type coolant and pure water. In this embodiment, the cooling medium in the flow path is pure water.

[0044] The flow direction of the fluid medium circulating between the power supply water cooling plate 3 and the heat exchanger 4 is shown in the attached Figure 1 The arrow in the middle indicates the direction.

[0045] The first medium flow path 1 and the second medium flow path 2 are composed of a plurality of segmented flow tubes, the plurality of segmented flow tubes are connected by connectors, and threaded sealing connectors are used at the bends of the flow paths.

[0046] Specifically, refer to the attached Figure 2 The first medium flow path 1 includes a first docking portion 11, a second docking portion 12 and a plurality of first flow tubes 14. The plurality of first flow tubes 14 are connected end to end through a first right-angle joint 13 to form a flow path. One end of the flow path is connected to the first outlet port 41 on the heat exchanger 4 through the first docking portion 11, and the other end of the flow path is connected to the first medium flow path port 31 of the power water cooling plate 3 through the second docking portion 12.

[0047] The second medium flow path 2 includes a third docking portion 21, a fourth docking portion 24 and a plurality of second flow tubes 23. The plurality of second flow tubes 23 are connected end to end through a second right-angle joint 22 to form a flow path. One end of the flow path is connected to the second outlet port 42 of the heat exchanger 4 through the third docking portion 21, and the other end of the flow path is connected to the second medium flow path port 32 of the power supply water cooling plate 3 through the fourth docking portion 24.

[0048] Wherein, the first right-angle joint 13 and the second right-angle joint 22 are both right-angle elbows.

[0049] The first outlet port 41 and the second outlet port 42 are arranged on the same side wall of the heat exchanger 4 , and the first medium flow path port 31 and the second medium flow path port 32 are arranged on the power supply water cooling plate 3 .

[0050] As attached Figure 3 Combined with Figure 4 As shown, the planes where the pipes of the heat exchanger 4 and the pipes of the power water cooling plate 3 are located are perpendicular to each other, and they need to be bent and guided to achieve connection. The first docking portion 11 and the third docking portion 21 are both connected by bent pipes, which are adjusted from short straight pipes to bent pipes, and an internally threaded copper joint is welded at the bent pipe joint to avoid the disadvantages of using short straight thin-walled copper pipes.

[0051] For details, refer to the attached Figure 5 The first docking portion 11 includes a group of first elbows 111 and a first internally threaded copper joint 112, and the first internally threaded copper joint 112 is connected to the first elbow 111. The second docking portion 12 includes a group of second elbows 211 and a second internally threaded copper joint 212, and the second internally threaded copper joint 212 is welded to the second elbow 211; wherein, an internally threaded copper joint is added to at least one side of each of the first elbow 111 and the second elbow 211.

[0052] Among them, the second lead-out port 42 located on the outside is shorter, and the corresponding third docking part 21 is shorter than the first docking part 11, and an internally threaded copper joint is welded thereon. The first lead-out port 41 located on the inside is longer and the front end is bent 90 degrees and then an internally threaded copper joint is welded thereon to enable horizontal output.

[0053] The first internal thread copper joint 112 and the second internal thread copper joint 212 are G1 / 4 internal thread welding joints with a thread depth of 10 mm. The first internal thread copper joint 112 and the second internal thread copper joint 212 are filled with sealant and then sealed with an external thread nylon joint.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
