Description

Technical Field

[0002] In the case of multiple heat exchange requirements, in the prior art, multiple liquid cooling components, such as liquid cooling plates or liquid cooling tanks, are generally connected in series or in parallel to a circulation flow path.

[0003] Parallel connection allows each heat exchange component to work independently without affecting each other. If a branch fails or its performance degrades, the other branches can continue to work without affecting the overall cooling capacity. It is often used in large heat exchange systems.

[0004] However, in a parallel system, due to differences in the placement of each liquid cooling component, the heat exchange medium in the main circuit cannot be well distributed to each parallel branch circuit, causing some branches to fail to meet the heat exchange requirements.

[0051] Example

[0052] Please refer to Figures 1 to 6 This embodiment provides a parallel heat exchange system 100, comprising a power element 111, a main liquid supply pipe 120, a branch pipe 130, and at least two liquid cooling units 150. The liquid cooling unit 150 has a liquid inlet 151, and the liquid cooling unit 150 is configured to exchange heat through a heat exchange medium. One end of the main liquid supply pipe 120 is connected to the power element 111, and the power element 111 is configured to supply liquid to the main liquid supply pipe 120. There are multiple branch pipes 130, one end of each of the multiple branch pipes 130 is connected to the other end of the main liquid supply pipe 120, and the other ends of the multiple branch pipes 130 are respectively connected to the liquid inlets 151 of the multiple liquid cooling units 150 in a one-to-one correspondence. The highest points of all the branch pipes 130 are located at the same height, and the highest points of the branch pipes 130 are higher than the highest liquid levels of all the liquid cooling units 150.

[0053] In this embodiment, by arranging the highest points of all branch pipes 130 at the same height and making the highest points of the branch pipes 130 higher than the highest liquid level heights of all the liquid cooling components 150, this arrangement allows the power element 111 to transport the heat exchange medium to each liquid cooling component 150 with the same height difference so that the lift of each branch pipe 130 is basically the same. In this way, the resistance of all branch pipes 130 can be close, thereby improving the problem that the main liquid supply pipe 120 cannot evenly distribute the heat exchange medium to each branch pipe 130.

[0054] It should be noted that the highest point of the branch pipe 130 being higher than the highest liquid level of all the liquid-cooling components 150 can be understood as meaning that the liquid level here is equivalent to the height from the ground to the liquid surface. For example, if all the liquid-cooling components 150 are located at the same height, then the liquid level of all of them is the same, and it is sufficient for the highest point of all the branch pipes 130 to be higher than the highest liquid level of any of them. If all the liquid-cooling components 150 are located at different heights, the highest point of the branch pipe 130 needs to be higher than the liquid level of the highest liquid-cooling component 150. This arrangement is intended to ensure that the height difference at which the power element 111 delivers heat exchange medium to each liquid-cooling component 150 is as uniform as possible, ensuring that the work performed by the power element 111 to overcome the weight of the heat exchange medium in each branch pipe 130 is the same. It should also be noted that there can be some deviation in the highest point of all the branch pipes 130 being located at the same height, which can be caused by manufacturing errors, assembly errors, and other factors. The size of the error can be determined according to the accuracy of flow distribution. If the accuracy requirement for uniform flow distribution is high, the error range needs to be controlled as small as possible. If the requirement for uniform flow distribution is not particularly high, the error range can be appropriately increased to reduce costs.

[0055] In this embodiment, the power element 111 may be a pump. Of course, the power element 111 may also be a compressor, a hydraulic motor or other components.

[0056] Furthermore, the main liquid supply pipeline 120 includes a liquid supply pipeline 121 and a distribution pipeline 123. The distribution pipeline 123 is sealed at both ends along its length. One end of the liquid supply pipeline 121 is connected to the middle of the length of the distribution pipeline 123, and the other end of the liquid supply pipeline 121 is connected to the power element 111. All branch pipelines 130 are connected to the side walls of the distribution pipeline 123.

[0057] In this embodiment, by configuring the main liquid supply pipe 120 in a "T" shape and connecting the branch pipes 130 to the side walls of the distribution pipe 123, the main liquid supply pipe 120 transports the fluid to the middle of the distribution pipe 123, whereupon the fluid flows through the distribution pipe 123 to both ends of the distribution pipe 123. Since both ends of the distribution pipe 123 are closed in the longitudinal direction, the fluid can only flow out through the branch pipes 130, thus forming a closed flow field. In this flow field, the fluid is constrained by the distribution pipe 123 and the branch liquid supply pipe 121 and must comply with the Bernoulli equation and the continuity equation, so that the fluid reaches a balanced state within the distribution pipe 123 and supplies liquid to all branch pipes 130 in a relatively uniform manner.

[0058] In this embodiment, the diameters of the liquid supply pipe 121 and the distribution pipe 123 are the same. The diameters of all branch pipes 130 are the same and smaller than the diameter of the main liquid supply pipe 120. Of course, in other embodiments of the present application, the diameters of the distribution pipe 123, the liquid supply pipe 121, and the branch pipes 130 can be set as needed.

[0059] In one embodiment, a plurality of partitions may be provided at intervals within the distribution pipe 123 to divide the internal space of the distribution pipe into a plurality of independent chambers, so that each chamber is connected to the liquid supply pipe 121 in a "Y" shape through a pipe. A plurality of branch pipes 130 may be connected to the plurality of chambers in a one-to-one correspondence. Secondly, in some other embodiments of the present application, the shape of the main supply pipe may also be set according to demand and cost budget. For example, in some embodiments, the main liquid supply pipe 120 may be a straight pipe, and the plurality of distribution pipes 123 may be directly connected to the end of the main liquid supply pipe 120 in a "Y" shape. It can be seen that the connection method of the plurality of branch pipes 130 to the main liquid supply pipe 120 can be selected in different connection methods according to demand, as long as it utilizes uniform airflow.

[0060] In this embodiment, all branch pipes 130 are connected to the side wall of the distribution pipe 123 in a symmetrical manner in the middle of the length direction of the distribution pipe.

[0061] This embodiment helps ensure that the flow rate of each branch pipe 130 is roughly equal through symmetrical arrangement, and also helps maintain the pressure balance inside the distribution pipe 123, because the fluid starts from the center point of the distribution pipe 123 and diffuses to the surrounding areas, reducing the possibility of local pressure fluctuations.

[0062] For example, when there are two branch pipes 130, one is symmetrically arranged on each side of the distribution pipe with respect to the main liquid supply pipe 120. When there are four branch pipes 130, two are symmetrically connected to each side of the main liquid supply pipe 120. The connection points of the branch pipes 130 connected on the same side can be equal to the distance from the liquid supply pipe 121. It can also be unequal, with the connection points of the branch pipes 130 connected on the same side being staggered but symmetrical on both sides. For example, four branch pipes 130 are provided. The first and second branch pipes 130 are provided on one side, while the third and fourth branch pipes are provided on the other side. However, the first and fourth branch pipes are symmetrical with respect to the liquid supply pipe 121, while the second and third branch pipes are symmetrical with respect to the liquid supply pipe 121.

[0063] Please refer to Figures 1 to 6 In this embodiment, all branch pipes 130 include a first connecting section 131, a second connecting section 132 and a third connecting section 133 connected in sequence. One end of the first connecting section 131 of all branch pipes 130 is connected to the side wall of the distribution pipe 123, and the other end extends upward. The second connecting section 132 of all branch pipes 130 is roughly horizontally arranged. The third connecting section 133 of all branch pipes 130 extends downward and is connected to the liquid inlet 151. The second connecting section 132 of all branch pipes 130 is the highest point of the corresponding branch pipe 130, and all the second connecting sections 132 are on the same horizontal plane.

[0064] This embodiment arranges the connecting pipe to be a first connecting section 131, a second connecting section 132 and a third connecting section 133 connected in sequence, and arranges the second connecting section 132 horizontally, and arranges the second connecting sections 132 of all branch pipes 130 to be the highest point of the corresponding branch pipes 130, and all the second connecting sections 132 are on the same horizontal plane, so as to facilitate better diversion.

[0065] Of course, in some other embodiments of the present application, the second connecting section may also be arranged in a substantially arc shape.

[0066] In this embodiment, the first connecting sections 131 of all branch pipes 130 extend vertically upward and have the same length. This same length ensures that all branch pipes 130 have the same length from their highest point to the distribution pipe, thereby ensuring that the pipe resistance of each pipe is as uniform as possible.

[0067] Please refer to Figures 1 to 6 In this embodiment, the parallel heat exchange system 100 further includes a plurality of distribution valves 114 , which are installed one-to-one in the plurality of branch pipes 130 , and the distribution valves 114 are configured to adjust the flow of the corresponding branch pipes 130 .

[0068] Since there are differences in the overall lengths of the branch pipes 130, this embodiment sets a distribution valve 114 in each branch pipe 130. In this way, during the overall debugging process, the flow of the corresponding branch flow channel can be adjusted by the distribution valve 114 to achieve uniform distribution.

[0069] In this embodiment, the parallel heat exchange system 100 further includes a support frame 170. The liquid cooling element 150 is a liquid cooling tank, wherein one liquid cooling tank is arranged above the other liquid cooling tank via a support member. The liquid inlet 151 is connected to the bottom of the liquid cooling tank.

[0070] In this embodiment, the liquid cooling element 150 is configured as a liquid cooling tank, allowing servers, data centers, and other equipment to be fully or partially immersed in the tank for heat exchange. The support frame 170 is provided to optimize space utilization, allowing the cooling tanks to be stacked vertically. The liquid inlet 151 is connected to the bottom of the tank, enhancing heat exchange.

[0071] Please refer to Figures 1 to 6 In this embodiment, the liquid cooling tank includes a tank body 153 and a partition plate 155. The partition plate 155 is disposed within the tank body 153 along its length, dividing the tank body 153 into a mutually independent liquid cooling chamber 157 and an overflow chamber 159. The liquid inlet 151 is connected to the bottom of the liquid cooling chamber 157, and the heat exchange medium in the liquid cooling chamber 157 can overflow into the overflow chamber 159 through the partition plate 155. The overflow chamber 159 is provided with a liquid outlet 161, which is connected to the liquid inlet 151 of the power element 111 through a pipeline.

[0072] In this embodiment, the liquid cooling tank is divided into a liquid cooling chamber 157 and an overflow chamber 159 by a partition plate 155, and the liquid inlet 151 is connected to the bottom of the liquid cooling chamber 157. The heat exchange medium in the liquid cooling chamber 157 can overflow into the overflow chamber 159 through the partition plate 155. This ensures that the heat exchange medium can fill the liquid cooling chamber 157, and the outlet pressure of the branch pipe 130 is consistent, which facilitates uniform diversion and better heat exchange.

[0073] In this embodiment, the parallel heat exchange system 100 further includes a heat exchanger 112 and a liquid storage tank 190. The inlet of the heat exchanger 112 is connected to the outlet of the power element 111 via a pipe, and the outlet of the heat exchanger 112 is connected to the main liquid supply pipe 120. The parallel heat exchange system 100 also includes a liquid storage tank 190, which has a liquid return port and a liquid discharge port. The liquid outlets 161 of all liquid cooling tanks are connected to the liquid return port, and the liquid discharge port is connected to the liquid inlet 151 of the power element 111 via a pipe.

[0074] In this embodiment, the heat exchanger 112 is provided to achieve better heat exchange, and the liquid storage tank 190 is provided to store excess heat exchange medium in the liquid storage tank 190 .

[0075] In this embodiment, the parallel heat exchange system 100 further includes a container 113 and a fan 115. The sidewalls of the container 113 are provided with mounting notches, into which the heat exchanger 112 is mounted. The top of the container 113 is provided with a mounting opening, into which the fan 115 is mounted. The liquid cooling tank, power element 111, and main liquid supply pipeline 120 are all located within the container 113.

[0076] In this embodiment, the parallel heat exchange system 100 is disposed in a container 113, thereby facilitating movement and installation. The fan 115 can be provided to better dissipate heat from the heat exchanger 112.

[0077] Please refer to Figures 1 to 6 In this embodiment, there may be four liquid cooling tanks, namely, a first liquid cooling tank 163, a second liquid cooling tank 164, a third liquid cooling tank 165, and a fourth liquid cooling tank 166. There are two support frames 170, namely, a first support frame 171 and a second support frame 173. There may be two liquid storage tanks 190, namely, a first liquid storage tank 191 and a second liquid storage tank 193. The first support frame 171 and the second support frame 173 are arranged on opposite sides of the container 113 along the width direction. Both the first support frame 171 and the second support frame 173 are three-layer support frames 170. The first liquid storage tank 191 is arranged at the lower layer of the first support frame 171. The second liquid cooling tank 164 is arranged at the middle layer of the first support frame 171. The second liquid cooling tank 164 is arranged at the upper layer of the first support frame 171. The second liquid storage tank 193 is arranged at the lower layer of the second support frame 173. The third liquid cooling tank 165 is arranged at the middle layer of the second support frame 173. The fourth liquid cooling tank 166 is disposed on the upper layer of the second support frame 173. The liquid inlets 151 of the first liquid cooling tank 163, the second liquid cooling tank 164, the third liquid cooling tank 165 and the fourth liquid cooling tank 166 are disposed on the same side.

[0078] Please refer to Figures 1 to 6Branch pipes 130 also have four sections: a first branch pipe 134, a second branch pipe 135, a third branch pipe 136, and a fourth branch pipe 137. One end of each of the first and second branch pipes 134, 135 is connected to the sidewall of one end of the distribution pipe, while the third and fourth branch pipes 136, 137 are connected to the sidewall of the other end of the distribution pipe. The first and fourth branch pipes 134, 137 are symmetrically arranged about the middle of the length of the distribution pipe 123. The second and third branch pipes 135, 136 are symmetrically arranged about the middle of the length of the distribution pipe 123. The first connecting sections 131 of the first, second, third, and fourth branch pipes 134, 135, 136, and 137 all extend vertically upward, with their ends reaching the top of the partition plate 155 between the second and fourth liquid cooling tanks 164, 166. Because the second and fourth liquid cooling tanks 164, 166 are installed at a higher position, the highest liquid level in each is flush with the partition plate 155. Therefore, it is only necessary that the end of the first connecting section 131 slightly protrudes from the top of the partition plate 155. In this way, the plane where the second connecting sections 132 of the first branch pipe 134, the second branch pipe 135, the third branch pipe 136, and the fourth branch pipe 137 are located will be higher than the liquid level in the second liquid cooling tank 164 and the fourth liquid cooling tank 166. The third connecting sections 133 of the first branch pipe 134, the second branch pipe 135, the third branch pipe 136, and the fourth branch pipe 137 all extend downward. The first branch pipe 134 is connected to the liquid inlet 151 of the first liquid cooling box. The second branch pipe 135 is connected to the liquid inlet 151 of the second liquid cooling box. The third branch pipe 136 is connected to the liquid inlet 151 of the third liquid cooling box. The fourth branch pipe 137 is connected to the liquid inlet 151 of the fourth liquid cooling box. Because the first, second, third, and fourth liquid-cooling tanks 163, 164, 165, and 166 are located in different locations, the first, second, third, and fourth branch pipes 134, 135, 136, and 137 have different lengths. However, all first connecting sections 131 and 132 have the same length, with only the third connecting sections 133 varying in length.

[0079] Please refer to Figures 1 to 6 The second connecting section 132 of the second branch pipe 135 and the third branch pipe 136 is provided with a distribution valve 114, and the third connecting section 133 of the first branch pipe 134 and the fourth branch pipe 137 is provided with a distribution valve 114. The distribution valve 114 can be a valve with flow control function such as a ball valve, flow valve, or solenoid valve.

[0080] The liquid outlets 161 of the first and second liquid cooling tanks 163 and 164 are connected to the liquid return port of the first liquid storage tank 191 through pipes. The liquid outlets 161 of the third and fourth liquid cooling tanks 165 and 166 are connected to the liquid return port of the second liquid storage tank 193 through pipes.

[0081] The liquid outlets 161 of the first and second liquid storage tanks 191 and 193 are connected to the liquid inlet 151 of the water pump via pipes. In this way, the heat exchange medium can circulate along the water pump, heat exchanger 112, liquid cooling tank and liquid storage tank 190 under the action of power element 111.

[0082] In other embodiments of the present application, the liquid cooling element 150 may also be a liquid cooling plate, a liquid cooling back plate, etc. The number of liquid cooling elements 150 may be two, three, or more. The number of distribution pipes 123 may also be two, three, or more. This application does not limit the number of liquid cooling elements 150 and distribution pipes 123.

[0083] In summary, the parallel heat exchange system 100 provided in the present application makes the highest points of all branch pipes 130 at the same height, and makes the highest points of the branch pipes 130 higher than the highest liquid level heights of all the liquid cooling parts 150. This setting can make the lifts of all branch pipes 130 the same, so that the resistances of all branch pipes 130 can be close, thereby improving the problem that the main liquid supply pipe 120 cannot evenly distribute the heat exchange medium to each branch pipe 130.
