Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid cooling plate technology, and in particular to a parallel water-cooled liquid cooling plate. Background Technology
[0002] A liquid cooling plate is a highly efficient thermal management component. It indirectly transfers heat from heat-generating devices to a coolant enclosed in a circulating pipeline via a cold plate (typically a closed cavity made of thermally conductive metals such as copper or aluminum), thus achieving rapid heat transfer and dissipation. When electronic equipment generates heat, the coolant in the pipes on the heat sink is pumped to the heat dissipation area, absorbs heat, becomes hot, and is then cooled by a cooler before recirculating back to the heat sink to continue absorbing heat. This cycle repeats continuously, maintaining the device's temperature within an acceptable range.
[0003] During the use of liquid cooling plates, the cooling effect is best when the cooling water is injected into the liquid cooling plate through the inlet. When the cooling water travels through the liquid cooling plate to the outlet, it has already absorbed a lot of heat during its travel through the liquid cooling plate, which reduces the heat absorption effect of the cooling water at the outlet, resulting in an uneven surface temperature of the liquid cooling plate.
[0004] Therefore, it is necessary to provide a new parallel water-cooled plate to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a parallel water-cooled plate.
[0006] The present invention provides a parallel water-cooled plate, comprising two plates symmetrically arranged and fixedly connected on opposite sides. One plate is fixedly provided with a liquid distributor on one side, and the other plate is provided with a liquid collector on the side away from the liquid distributor.
[0007] The plate has multiple flow channels on one side, each flow channel is U-shaped, and a partition is fixedly installed in each flow channel. Multiple first protrusions are provided on one side of the inner wall of the flow channel and one side of the partition. One end of the partition is fixedly connected to one end of the inner wall of the flow channel, and a second protrusion is fixedly installed on the other end of the partition.
[0008] The liquid separator includes a cavity, one side of which is fixedly connected to one side of the plate. An inlet pipe is fixedly provided at the top of the cavity. Three water-blocking blocks are provided inside the cavity, and the three water-blocking blocks are distributed in a triangular pattern. Guide plates are fixedly provided on both sides of the inner wall of the cavity. Multiple first connecting pipes are fixedly provided at the bottom of the cavity. The inner cavity of the cavity is connected to multiple flow channel cavities through the multiple first connecting pipes.
[0009] Preferably, the liquid collector includes a liquid collection chamber, one side of which is fixedly connected to the side of another plate away from the cavity. The top of the liquid collection chamber is fixedly provided with a water outlet, and the bottom of the liquid collection chamber is provided with a plurality of second connecting pipes. The liquid collection chamber communicates with a plurality of flow channel cavities through the plurality of second connecting pipes respectively.
[0010] Preferably, the first connecting pipe and the second connecting pipe connected to the same flow channel are located on both sides of the partition.
[0011] Preferably, the water-blocking block is triangular in shape, and the three corners of the water-blocking block are rounded.
[0012] Preferably, the plate is an aluminum plate or a copper plate.
[0013] Compared with related technologies, the parallel water-cooled plate provided by this utility model has the following beneficial effects:
[0014] 1. By allowing coolant to flow into four channels, each channel is equipped with baffles to extend the flow path of the coolant. Multiple first and second protrusions are also provided to reduce the inner diameter of the channels. This allows the coolant to change its flow speed by narrowing the inner diameter, thus creating turbulence and making the coolant temperature more uniform. The inlets and outlets of the multiple channels are located at the same end and are alternately arranged, allowing the coolant to exchange heat with the incoming coolant during flow, resulting in a more even surface temperature of the plate.
[0015] 2. The coolant is pumped into the inlet pipe, allowing it to enter the cavity. The coolant impacts a water-blocking block located above, which divides the coolant into two streams. Then, under the action of two guide plates, the two streams of coolant impact two more water-blocking blocks, thus dividing the two streams into four streams. By setting up water-blocking blocks, the coolant can be more easily divided into four streams, which is beneficial for the coolant to be injected into the four flow channels.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please refer to the following: Figures 1-7 ,in, Figure 1 A schematic diagram of the overall structure of a parallel water-cooled plate provided by this utility model. Figure 1 ; Figure 2 A schematic diagram of the overall structure of a parallel water-cooled plate provided by this utility model.

Figure 6 for Figure 5 The diagram shows a cross-sectional view of the separator. Figure 7 for Figure 2 The diagram shows the overall structure of the liquid collector.
[0026] In the specific implementation process, such as Figures 1-7 As shown, it includes two plates 1, which are aluminum plates or copper plates. The two plates 1 are arranged symmetrically and are fixedly connected on opposite sides. One side of one plate 1 is fixedly provided with a liquid separator 2, and the other side of the plate 1 away from the liquid separator 2 is provided with a liquid collector 3.
[0027] Multiple flow channels 11 are provided on one side of the plate 1. The multiple flow channels 11 are all U-shaped. Baffles 12 are fixedly installed in each of the multiple flow channels 11 to extend the flow path of the coolant. Multiple first protrusions 13 are provided on one side of the inner wall of the flow channel 11 and one side of the baffle 12. One end of the baffle 12 is fixedly connected to one end of the inner wall of the flow channel 11, and the other end of the baffle 12 is fixedly provided with a second protrusion 14 to reduce the inner diameter of the flow channel 11. This allows the coolant to change its flow speed by reducing the inner diameter, thereby allowing the coolant to tumble by continuously changing its flow speed, thus making the temperature of the coolant more uniform.
[0028] The separator 2 includes a cavity 21, one side of which is fixedly connected to one side of the plate 1. An inlet pipe 22 is fixedly installed at the top of the cavity 21. Three water-blocking blocks 23 are arranged in a triangular pattern inside the cavity 21, with rounded corners. Guide plates 24 are fixedly installed on both sides of the inner wall of the cavity 21. Multiple first connecting pipes 25 are fixedly installed at the bottom of the cavity 21, allowing the contents of the cavity 21 to be distributed through the multiple first connecting pipes 25. The coolant is pumped into the inlet pipe 22 through multiple flow channels 11, so that the coolant enters the cavity 21. The coolant will hit a water blocking block 23 located above, so that the coolant is divided into two streams by the water blocking block 23. Then, under the action of two guide plates 24, the two streams of coolant will hit two other water blocking blocks 23 respectively, so that the two streams of coolant will be divided into four streams. The four streams of coolant flow into the four flow channels 11 through four first connecting pipes 25 respectively.
[0029] The liquid collector 3 includes a liquid collecting chamber 31. One side of the liquid collecting chamber 31 is fixedly connected to the side of another plate 1 away from the cavity 21. An outlet 32 is fixedly provided at the top of the liquid collecting chamber 31. A plurality of second connecting pipes 33 are provided at the bottom of the liquid collecting chamber 31. The liquid collecting chamber 31 is connected to the inner cavity of a plurality of flow channels 11 through the plurality of second connecting pipes 33. The first connecting pipe 25 and the second connecting pipe 33 connected to the same flow channel 11 are located on both sides of the partition plate 12. The coolant in the four flow channels 11 flows into the liquid collecting chamber 31 from the four second connecting pipes 33 and flows out from the outlet 32.
[0030] The working principle of this utility model is as follows: During use, the coolant is pumped into the inlet pipe 22, allowing it to enter the cavity 21. The coolant impacts a water-blocking block 23 located above, splitting the coolant into two streams. Then, under the action of two guide plates 24, the two streams of coolant impact two more water-blocking blocks 23, further splitting the two streams into four streams. These four streams flow into four flow channels 11 through four first connecting pipes 25. A baffle 12 is provided to extend the flow path of the coolant, and multiple first protrusions 13 and second protrusions 14 are provided to reduce the inner diameter of the flow channel 11. This allows the coolant to change its flow speed by narrowing the inner diameter, thereby causing the coolant to tumble and become more uniform in temperature by continuously changing its flow speed. Finally, the coolant in the four flow channels 11 bypasses the baffle 12 and flows into the collection chamber 31 from the four second connecting pipes 33, and then flows out from the outlet 32.
[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
