[0044] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0045] It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0047] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0048] It should be noted that the "up", "down", "left", "right" and other directional words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "below", it can not only be directly connected to another element "on" or "below", but also indirectly connected to another element "on" or "below" through an intermediate element.

[0049] With the development of technology, the power of semiconductor chips is constantly improving, and the requirements for liquid cooling plates are also getting higher and higher. Usually, the liquid cooling plate includes a plurality of channels connected to each other, and the channels have a plurality of flow channels. When the coolant enters the flow channel, it is easy to appear uneven distribution, resulting in more coolant in some flow channels and less coolant in some flow channels. Moreover, due to the different heat exchange areas of different flow channels and heat sources, the overall utilization rate of the coolant is reduced, which affects the heat dissipation efficiency and temperature distribution uniformity of the liquid cooling plate.

[0050] In view of this, the embodiments of the present application provide a liquid cooling plate and an electronic computing device, for providing a new structure of liquid cooling plate.

[0051] As shown in Figure 1 The embodiments of the present application provide a liquid cooling plate, wherein, as shown in Figure 2As shown, the liquid cooling plate includes a plurality of channels 1 connected in sequence, adjacent channels 1 can be connected in a head-to-tail manner to form a coolant flow path of the liquid cooling plate, the channels 1 can be integrally formed on the bottom plate, for example, can be produced by milling process or the like, or can be separated by the separation part 4, for example, by welding or the like to form the channel 1. Adjacent channels 1 are connected by the communication part 3, Figure 2 The position indicated by the dashed line is the communication part 3, which can be integrally formed with the channel 1 on the bottom plate of the liquid cooling plate, and the channel 1 is provided with a separation part 2 to separate the channel 1 into a plurality of flow channels. Specifically, part of the separation part 2 can extend into the communication part 3. The length of the part of each separation part 2 extending into the communication part 3 in the same channel 1 gradually increases or gradually decreases according to a predetermined rule. Specifically, in a specific embodiment, as shown in the figure, the arrow direction in the figure is the flow direction of the coolant, the coolant flows from the previous channel 1 into the next channel 1 in the direction shown in the figure, and the length of each separation part 2 extending into the connection part 3 gradually increases in the direction away from the next channel 1. Figure 4

[0052] Through such a design, the coolant can be collected and then divided before flowing out of the previous channel 1 and entering the next channel 1, thereby re-distributing the coolant flowing into each flow channel, which is beneficial to the uniform flow of the coolant into the next channel 1, and the coolant with insufficient heat exchange can be mixed with the coolant with sufficient heat exchange, so that the coolants can exchange heat with each other, and after mixing, the coolants can be re-distributed, which is beneficial to improving the utilization efficiency of the coolants.

[0053] Specifically, in the direction away from the separation part 4, the length of each separation part 2 extending into the same communication part 3 gradually increases.

[0054] In this way, the possibility of the coolant being interfered by the separation part 2 of the adjacent flow channel when flowing into the communication part 3 can be reduced, thereby reducing the accumulation of the coolant in the flow channel, and more beneficial to the collection and re-distribution of the coolant in the communication part 3, thereby improving the overall heat exchange capacity of the liquid cooling plate.

[0055] As shown in the figure, Figure 4 In a possible embodiment, at least one end of the separation part 2 is provided with a guide part 24 in the liquid flow direction, specifically, the guide part 24 can be provided at one end of the separation part 2 extending into the communication part 3, and the coolant can flow along the guide part 24 to enter different flow channels.

[0056] Through such a design, the uniformity of the distribution of the coolant flowing into the next channel can be further improved, thereby improving the overall heat exchange capacity of the liquid cooling plate, improving the heat dissipation efficiency and the uniformity of temperature distribution.

[0057] As shown in the figure, Figure 2 ​As shown, in a possible implementation, the at least one communication part 3 is also provided with a partition 2, and the partition 2 of the communication part 3 has a preset distance from the partition 2 of the channel 1 that communicates with the communication part 3. That is, the partition 2 of the communication part 3 is not connected with the partition 2 of the channel 1, and the coolant needs to be re-distributed before entering the flow channel.

[0058] When the distance between the channels 1 that communicate with each other is long, that is, the length of the communication part 3 is long, the partition 2 can be arranged in the communication part 3 to separate the communication part 3 into different flow channels, which is beneficial to the uniform flow of the coolant in the flow channel, thereby reducing the possibility that the coolant concentrates on one side of the communication part 3 during the flow process of the communication part 3, and then causes uneven distribution when entering the flow channel of the next channel 1.

[0059] As shown in FIG. 1, the liquid cooling plate can include a plurality of channels 1, and the plurality of channels 1 are arranged in a plurality of rows along the circumferential direction of the liquid cooling plate. Figure 2 As shown, in a possible implementation, the channel 1 of the liquid cooling plate can include a first channel 13 and a second channel 14, specifically, can include a plurality of first channels 13 and a plurality of second channels 14, wherein the first channel 13 is arranged along the circumferential direction of the liquid cooling plate and can surround a preset area, and the second channel 14 is located in the preset area, that is, the first channel 13 can be surrounded on the outer side of the second channel 14. Specifically, the first channel 13 can communicate with the liquid inlet 11, the second channel 14 can communicate with the liquid outlet 12, and the coolant flows into the second channel 14 through the first channel 13.

[0060] Because the coolant absorbs heat emitted by the heat source during the flow process, in general, the temperature of the coolant in the first channel 13 is lower than the temperature of the coolant in the second channel 14. Such a design can make the coolant with a lower temperature (the coolant in the first channel 13) surrounded on the outer side of the coolant with a higher temperature (the coolant in the second channel 14), and the coolant in the first channel 13 can exchange heat with the coolant in the second channel 14, thereby reducing the temperature of the coolant in the second channel 14 and reducing the temperature difference between the coolant in the first channel 13 and the coolant in the second channel 14, which is beneficial to balancing the overall temperature of the liquid cooling plate, and further beneficial to making each heat source in a similar temperature environment, which is more in line with actual use requirements.

[0061] In a possible implementation, the channel 1 that communicates with the liquid inlet 11 of the liquid cooling plate is arranged along the circumferential direction of the liquid cooling plate and surrounds a preset area, and the channel 1 that communicates with the liquid outlet 12 is located in the preset area. Specifically, as shown in FIG. 1, the channel 1 can also include a third channel 15, a fourth channel 16, and a fifth channel 17, and each channel 1 communicates in sequence, specifically, the second channel 14, the third channel 15, the fourth channel 16, and the fifth channel 17 can be arranged in a serpentine shape in the area surrounded by the first channel 13. Figure 2 Figure 2 ​As shown, in a specific arrangement of the channels 1, the liquid inlet 11 and the liquid outlet 12 of the channel 1 are located on the same side of the liquid cooling plate, and the channel 1 directly connected with the liquid inlet 11 and the channel 1 directly connected with the liquid outlet 12 are arranged adjacently, i.e. Figure 2 As shown, the fifth channel 17 and the first channel 13 are arranged adjacently.

[0062] Through such design, when the coolant flows into the liquid cooling plate, it first flows along the circumference of the liquid cooling plate and then flows at the middle position of the liquid cooling plate, so that the newly-inflowed low-temperature coolant surrounds the high-temperature coolant which has already exchanged heat with the heat source, facilitating the heat exchange between the low-temperature coolant and the high-temperature coolant, thereby improving the overall heat exchange efficiency of the coolant.

[0063] Specifically, as shown, Figure 2 The liquid inlet 11 and the liquid outlet 12 can be arranged adjacently, which can make the coolant in the channel 1 directly connected with the liquid inlet 11 exchange heat with the coolant in the channel 1 directly connected with the liquid outlet 12, and the coolant of the liquid inlet 11 can be used to exchange heat with the heat source near the liquid outlet 12, thereby improving the heat dissipation capacity of the area near the liquid outlet 12 of the liquid cooling plate and improving the heat dissipation efficiency of the liquid cooling plate, which is more in line with the actual use demand.

[0064] As shown, Figure 3 In a possible implementation, the third partition 23 is provided with a guide portion 24 which can be used to make the coolant flow to the side close to the liquid outlet 12.

[0065] Through such design, the flow passage close to the liquid outlet 12 can be distributed to more coolant, thereby improving the heat exchange capacity of the liquid cooling plate near the liquid outlet 12, which is more in line with the actual use demand.

[0066] As shown, Figure 1 The embodiment of the present application provides a liquid cooling plate, wherein, Figure 2 and Figure 3As shown, the liquid cooling plate includes a channel 1, the channel 1 is provided with a partition 2, specifically, the partition 2 is arranged along the extension direction of the channel 1, and the partition 2 separates the channel 1 into multiple flow channels. Through such a design, the coolant can be uniformly distributed in the channel 1, thereby increasing the heat exchange area of the liquid cooling plate and improving the heat exchange performance of the liquid cooling plate. The partition 2 can include a first partition 21, a second partition 22, and a third partition 23. Specifically, the channel 1 in communication with the liquid inlet 11 can be provided with the first partition 21, the second partition 22, and the third partition 23. The first partition 21 and the second partition 22 can be provided in multiple numbers, respectively. The first partition 21 and the second partition 22 are located on opposite sides of the third partition 23. The partition 2 can be provided with a guide portion 24 located on one side of the partition 2 close to the liquid inlet 11 of the channel 1. The guide portion 24 is used to make the coolant flow to both sides of the third partition 23. Specifically, each partition 2 can be provided with a guide portion 24, so that the coolant can flow to the flow channels located on both sides of the channel 1 in the width direction. Specifically, the first partition 21 and the second partition 22 can be provided in multiple numbers, respectively. As the distance between the first partition 21 and the second partition 22 and the third partition 23 increases, the distance between each first partition 21 and each second partition 22 and the liquid inlet 11 also increases.

[0067] Through such a design, the uniform distribution of the coolant can be facilitated, thereby improving the heat exchange capacity of the liquid cooling plate and the uniformity of the temperature distribution of the heat source of the liquid inlet 11.

[0068] The guide portion 24 is arranged on one side of the partition 2 close to the liquid inlet 11. When the coolant flows into the channel 1, it can come into contact with the guide portion 24, and part of the coolant can flow along the guide portion 24. Under normal circumstances, the liquid inlet 11 is arranged centrally with respect to the channel 1. After entering the channel 1, the coolant can flow to the flow channels located on both sides of the channel 1 under the action of the guide portion 24, thereby reducing the possibility of uneven distribution of the coolant in the middle and on both sides of the flow channels.

[0069] In one possible implementation, the thickness of the third partition 23 is greater than the thickness of the first partition 21 and the second partition 22, and as the distance between the first partition 21 and the second partition 22 and the third partition 23 increases, the thickness of each first partition 21 and each second partition 22 gradually decreases.

[0070] Since the thickness of the third partition 23 is large, it can hinder the flow of the coolant, thereby facilitating the distribution of the coolant, and facilitating the uniform distribution of the coolant. As the direction away from the third partition 23, the thickness of the first partition 21 and the second partition 22 gradually decreases, which can reduce the hindrance of the coolant 2 to the coolant, thereby facilitating the flow of the coolant.

[0071] As shown in FIG. 1, the liquid cooling plate includes a channel 1, the channel 1 is provided with a partition 2, specifically, the partition 2 is arranged along the extension direction of the channel 1, and the partition 2 separates the channel 1 into multiple flow channels. Through such a design, the coolant can be uniformly distributed in the channel 1, thereby increasing the heat exchange area of the liquid cooling plate and improving the heat exchange performance of the liquid cooling plate. The partition 2 can include a first partition 21, a second partition 22, and a third partition 23. Specifically, the channel 1 in communication with the liquid inlet 11 can be provided with the first partition 21, the second partition 22, and the third partition 23. The first partition 21 and the second partition 22 can be provided in multiple numbers, respectively. The first partition 21 and the second partition 22 are located on opposite sides of the third partition 23. The partition 2 can be provided with a guide portion 24 located on one side of the partition 2 close to the liquid inlet 11 of the channel 1. The guide portion 24 is used to make the coolant flow to both sides of the third partition 23. Specifically, each partition 2 can be provided with a guide portion 24, so that the coolant can flow to the flow channels located on both sides of the channel 1 in the width direction. Specifically, the first partition 21 and the second partition 22 can be provided in multiple numbers, respectively. As the distance between the first partition 21 and the second partition 22 and the third partition 23 increases, the distance between each first partition 21 and each second partition 22 and the liquid inlet 11 also increases. Figure 3As shown, in one possible implementation, the partition 2 may include a plurality of first partitions 21 and / or a plurality of second partitions 22.

[0072] This design allows channel 1 to be divided into multiple flow channels, which facilitates the uniform distribution of coolant within channel 1, thereby increasing the heat exchange area of ​​the liquid cooling plate and improving its heat exchange performance.

[0073] In one possible implementation, the number of partitions 2 in channel 1 can gradually increase or decrease along the extension direction of channel 1. Specifically, the density of partitions 2 in channel 1 gradually increases according to a preset rule along the liquid flow direction.

[0074] This design reduces the cross-sectional area of ​​the flow channel near the outlet 12, thereby increasing the outflow velocity of the coolant and increasing the heat exchange area. This enhances the heat exchange capacity of the liquid cooling plate at the outlet 12, resulting in a more balanced overall heat exchange capacity of the liquid cooling plate. It also reduces the temperature difference between the heat sources at the inlet 11 and the outlet 12. When the liquid cooling plate is used in electronic computing devices, it can effectively control the temperature between each chip 51, keeping each chip 51 at a similar temperature and improving the overall working efficiency of the electronic computing device.

[0075] like Figure 3 As shown, in one possible implementation, the distance between each first partition 21 and each second partition 22 and the liquid inlet 11 of the channel 1 gradually increases or decreases according to a preset rule. Specifically, along the direction away from the third partition 23, the distance between each first partition 21 and each second partition 22 and the liquid inlet 11 of the channel 1 gradually increases, that is, the closer the partition 2 is to the sides of the channel 1, the farther the distance between it and the liquid inlet 11 is, and the closer the partition 2 is to the middle of the channel 1, the closer the distance between it and the liquid inlet 11 is.

[0076] This design facilitates the flow of coolant to the channels 1 on both sides under the action of the guide section 24, reducing the possibility of the coolant being blocked by the partition section 2 during its flow to both sides, which could lead to uneven distribution of coolant.

[0077] Specifically, such as Figure 3 As shown, the first partition 21 and the second partition 22 can be symmetrically arranged about the third partition 23. This design is more conducive to the flow of coolant into the channels on both sides.

[0078] like Figure 3 As shown, in one possible implementation, the guide portion 24 is an inclined surface. Specifically, the partition portion 2 can be processed by beveling to form an inclined surface in the partition portion 2.

[0079] Such a design has the advantages of simple structure and convenient processing. Meanwhile, such a design can also reduce the influence of the thickness of the partition portion 2 on the flow of the coolant, and is conducive to the rapid flow of the coolant into the flow channels, and reduces the possibility of the aggregation and blockage of the coolant at the liquid inlet 11.

[0080] As shown in Figure 3 a possible implementation, the inclined guiding portion 24 is located on the side of the first partition portion 21 and the second partition portion 22 away from the third partition portion 23, and is inclined toward the direction close to the third partition portion 23. Specifically, the inclined surfaces of the first partition portions 21 are located in the same plane, and the inclined surfaces of the second partition portions 22 are located in the same plane.

[0081] Through such a design, the flow of the coolant along the guiding portion 24 to the flow channels on both sides of the channel 1 can be more conducive, thereby reducing the interference of the partition portion 2 on the flow of the coolant, reducing the possibility of the more distribution of the coolant in the middle flow channel and the less distribution of the coolant on both sides, making the overall distribution of the coolant more uniform, and thereby improving the overall heat exchange capacity of the liquid cooling plate.

[0082] As shown in Figure 5 a possible implementation, the liquid cooling plate includes a plurality of channels 1, and each channel 1 is sequentially communicated, and the adjacent channels 1 have a preset included angle.

[0083] Through such a design, the arrangement of the channels 1 can be adjusted, so that the channels 1 can be more uniformly distributed inside the liquid cooling plate, thereby improving the overall heat exchange capacity of the liquid cooling plate.

[0084] In a possible implementation, the liquid cooling plate includes a plurality of channels 1, and each channel 1 is arranged in parallel with each other.

[0085] Such a design is conducive to the uniform flow of the coolant in each channel 1, and reduces the possibility of the coolant deviating to one side during the flow.

[0086] As shown in Figure 5 a possible implementation, along the extension direction of the channel 1, the cross-sectional area of the channel 1 gradually increases or gradually decreases according to a preset rule. Specifically, along the flow direction, the cross-sectional area of the channel 1 gradually decreases according to a preset rule. The decreasing manner can be stepwise, that is, the cross-sectional areas of the adjacent channels 1 are different, or the decreasing manner can be gradual, that is, the cross-sectional area of the same channel 1 gradually decreases. In a possible implementation, the cross-sectional area of the second channel 14 can be half of the cross-sectional area of the first channel 13.

[0087] Since the channels 1 of the liquid cooling plate are connected in series and the coolant flow rate of each channel 1 is the same, when the cross-sectional area of ​​channel 1 decreases, the coolant has a higher flow velocity in the channel 1, thereby enhancing the heat transfer coefficient of the channel 1 near the liquid outlet 12, and thus improving the heat transfer capacity of the channel 1 in this area. This is beneficial to improving the overall heat transfer capacity of the liquid cooling plate and is more in line with actual usage requirements.

[0088] Based on the liquid cooling plate provided in the above embodiments, this application also provides an electronic computing device, which may include the liquid cooling plate involved in any of the above embodiments. Since the liquid cooling plate has the above technical effects, the electronic computing device including the liquid cooling plate also has the corresponding technical effects, which will not be repeated here.

[0089] Along the thickness direction of the liquid cooling plate, the liquid cooling plate has a first surface and a second surface on opposite sides. Both the first surface and the second surface can be used to contact the heat source (i.e., the chipset 5). This design can increase the heat exchange area of ​​the liquid cooling plate, improve the heat exchange efficiency of the liquid cooling plate, and better meet the actual use requirements.

[0090] like Figures 6 to 8 As shown, in one possible implementation, the liquid cooling plate can be used to dissipate heat from the chipset 5 of the electronic computing device. The chipset 5 may include two, three, four, or even more chips 51, and the chips 51 of the same chipset 5 are connected in parallel. Specifically, in the projection along the thickness direction of the liquid cooling plate, the chips 51 of the same chipset 5 are located within the projection range of the same channel 1.

[0091] This design allows the chips 51 of the same chipset 5 to be in similar temperature environments, thus making the temperatures of each chip 51 in the same chipset 5 the same or similar, which is beneficial to the overall operation of the electronic computing device.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
