Embodiments of the present disclosure provide a heat dissipation device. The heat dissipation device comprises a first main pipeline, a plurality of branch pipelines, a second main pipeline and a regulating component. The cooling liquid flows from the first main pipeline, through the plurality of branch pipelines, into the second main pipeline, and flows out of the heat dissipation device from the second main pipeline. The coolant dissipates heat from the plurality of functional components as it flows from the plurality of branch lines to the second main line. The adjusting component controls the flow distribution of the cooling liquid entering different branch pipelines according to the temperature of the cooling liquid at the communication part of at least one branch pipeline and the second main pipeline.
Fig. 1 schematically illustrates an application scenario of a heat dissipation device according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the application scenario includes an electronic device 100, and the electronic device 100 may be a server, for example.
The electronic device 100 includes a plurality of functional components, which may be, for example, a plurality of CPUs and a storage device. The CPU0 and the CPU1 in the electronic device 100 are exemplarily shown in fig. 1.
The heat dissipation device according to the embodiment of the present disclosure may dissipate heat for different functional components through different pipes, for example. According to the embodiment of the present disclosure, the heat dissipation device can adjust flow distribution for different pipelines, for example, to perform heat dissipation on multiple functional components in the electronic device 100 in a targeted manner, so that the degree of heat dissipation is large for functional components with higher temperatures, and the degree of heat dissipation is small for functional components with lower temperatures.
For example, in the scenario shown in fig. 1, if the power consumption of the CPU0 is low and the temperature of the CPU0 is low, and the power consumption of the CPU1 is high and the temperature of the CPU1 is high, the heat dissipation device according to the embodiment of the disclosure dissipates heat to a greater extent than to the CPU1 than to the CPU 0.
Fig. 2A schematically illustrates a schematic view of a heat dissipation device 200 according to an embodiment of the disclosure.
As shown in fig. 2A, the heat dissipation device 200 includes a first main pipeline 210, a plurality of branch pipelines 220, a second main pipeline 230, and a regulation part 240.
Each of the plurality of branch lines 220 is in communication with the first main line 210, respectively. For example, the plurality of branch lines 220 include a branch line 2201 and a branch line 2202, and the branch line 2201 and the branch line 2202 communicate with the first main line 210, respectively.
The second main line 230 communicates with each branch line. For example, second main conduit communicates with branch conduit 2201 and branch conduit 2202, respectively.
The cooling fluid for heat dissipation flows from the first main pipeline 210, through the plurality of branch pipelines 220, into the second main pipeline 230, and flows out of the heat dissipation apparatus 200 from the second main pipeline 230. The coolant dissipates heat from the various functional components as it flows from the various branch lines to second main line 230.
According to embodiments of the present disclosure, the cooling fluid may be, for example, water having a temperature within a range. For example, water having a temperature of 2 to 17 c may be used.
For example, the coolant enters branch line 2201 and branch line 2202 via first main line 210. A partial region of branch line 2202 may be laid, for example, on the upper surface of CPU1, and the coolant flowing through branch line 2202 and to second main line 230 may remove heat from CPU1 and dissipate heat from CPU 1. Similarly, a portion of branch conduit 2201 may be laid, for example, on the upper surface of CPU0, and the coolant flowing through branch conduit 2201 and to second main conduit 230 may carry away heat from CPU0, thereby dissipating heat from CPU 0.
According to an embodiment of the present disclosure, as shown in fig. 2A, the adjustment member 240 may be located in the second main pipeline, for example.
As shown in fig. 2A, cold water from first main conduit 210 enters branch conduits 2201 and 2202, respectively. The cold water in branch line 2201 flows around CPU0, taking heat from CPU0 and the hot water, having an increased temperature, flows out of second main line 230. Similarly, the cold water in branch line 2202 flows around the CPU1, taking heat away from the CPU1, and the hot water with its temperature raised flows out of the second main line 230.
The adjusting part 240 is configured to control the distribution of the coolant flow into the different branch lines according to the temperature of the coolant at the communication of at least one of the plurality of branch lines 220 with the second main line 230.
According to an embodiment of the present disclosure, each of the plurality of branch lines 220 may, for example, include a first end and a second end. Wherein each of the first ends is in communication with a first main conduit 210, and wherein the cooling fluid enters the plurality of branch conduits via each of the first ends and enters a second main conduit 230 from each of the second ends. The temperature of the coolant at the communication of at least one of the plurality of branch lines 220 with the second main line 230 may be, for example, the temperature of the coolant at the respective second ends.
According to the embodiment of the disclosure, the heat dissipation device can adjust flow distribution for different branch pipelines, and adjust the flow distribution of the cooling liquid in different branch pipelines according to the heat dissipation degree required by at least one functional component aimed by the branch pipeline, so that the distribution of the cooling liquid is more reasonable.
Fig. 2B schematically illustrates a partial enlarged view of the second conduit 230 according to an embodiment of the disclosure.
As shown in fig. 2B, second main conduit 230 may include, for example, a transfer valve 231 and a communication conduit 232. The switching valve 231 is used to communicate with the plurality of branch pipes 220, and the coolant in the plurality of branch pipes 220 is merged at the switching valve 231 and then flows out from the communication pipe.
As shown in fig. 2B, the regulating member 240 may be located in the valve 231.
According to an embodiment of the present disclosure, the adjusting part 240 may be located in the second main pipeline 230, a first side of the adjusting part 240 communicates with a first branch pipeline of the plurality of branch pipelines 220, and a second side of the adjusting part 240 communicates with a second branch pipeline of the plurality of branch pipelines. As shown in fig. 2B, a first side of the regulating member 240 communicates with a first branch line 2202, and a second side of the regulating member 240 communicates with a second branch line 2201. According to an embodiment of the present disclosure, adjusting component 240 may control the distribution of coolant flow into different branch lines based on the temperature difference between the coolant in first branch line 2202 and the coolant in second branch line 2201.
According to the embodiment of the present disclosure, in the case where there is a temperature difference between the coolant in the first branch line 2202 and the coolant in the second branch line 2201, the adjustment member 240 is deformed according to the temperature difference to control the distribution of the flow rate of the coolant entering the first branch line 2202 and the second branch line 2201 by the deformation.
According to the embodiment of the present disclosure, the distribution of the coolant flow can be adjusted by the deformation of the adjusting member 240, and the method is simple and easy to implement.
For example, the adjustment member 240 may be a structure made of a temperature-sensitive material that bends toward the side where the temperature of the coolant in the first branch pipe 2202 or the second branch pipe 2201 is lower in the case where there is a temperature difference between the coolant in the first branch pipe 2202 and the coolant in the second branch pipe 2201.
According to an embodiment of the present disclosure, the temperature sensitive material may be a material sensitive to temperature, and the deformation is different at different temperatures. The structure made of the temperature-sensitive material can be a baffle plate, for example. The baffle may be placed between the communication of first branch line 2202 with second main line 230 and the communication of second branch line 2201 with second main line 230.
For example, in the scenario shown in fig. 2B, a flap is placed between the communication of first branch line 2202 with second main line 230 and the communication of second branch line 2201 with second main line 230. The first side of the baffle plate is in contact with the cooling liquid in the first branch pipeline, and the second side of the baffle plate is in contact with the cooling liquid in the second branch pipeline. When the temperatures of the coolant in the first branch line 2202 and the second branch line 2201 are different, the expansion degree of the side having the higher temperature in the baffle is larger than that of the side having the lower temperature, and the baffle is bent toward the side having the lower temperature, thereby adjusting the flow distribution of the coolant in the first branch line 2202 and the second branch line 2201.
Fig. 3 schematically illustrates a partial schematic view of a heat dissipation device 200 according to another embodiment of the present disclosure.
As shown in fig. 3, the heat dissipation device 200 further includes a limiting member 310 based on the foregoing embodiments shown in fig. 2A and fig. 2B. The limiting member 310 may limit the degree of deformation of a structure made of a temperature sensitive material, for example. For example, in the scenario shown in fig. 3, the limiting member 310 is used to limit the bending degree of the flap, so as to prevent the flap from being bent too much to cause permanent deformation.
According to an embodiment of the present disclosure, as shown in fig. 3, a limiting member may be disposed between a pipe wall of second main pipe 230 and a structure made of a temperature-sensitive material, for example.
According to some further embodiments of the present disclosure, the adjustment member 240 may include a moving member. When there is a difference in temperature between the coolant in the first branch pipe 2202 and the coolant in the second branch pipe 2201, the moving member moves so as to decrease the branch pipe flow rate at which the temperature of the coolant in the first branch pipe 2202 or the second branch pipe 2201 is low, and/or to increase the branch pipe flow rate at which the temperature of the first branch pipe 2202 or the second branch pipe 2201 is high.
According to an embodiment of the present disclosure, the moving part may include, for example, a temperature sensor. The temperature sensor detects the temperature of the coolant on both sides of the moving member and controls the moving member to move toward the side with the lower temperature, so that the flow rate of the branch line on the side with the higher temperature is increased and the flow rate of the branch line on the side with the lower temperature is decreased.
In this embodiment, the heat dissipation device 200 may further include a limiting member for limiting a moving distance of the moving member to prevent the moving member from blocking the branch pipeline.
According to some other embodiments of the present disclosure, the adjusting component 240 may control the distribution of the coolant flow into different branch lines according to the temperature of the coolant at the communication of each branch line.
For example, adjustment component 240 may control the distribution of coolant flow into different branch lines based on the temperature at the location of first branch line 2202 in communication with second main line 2201, and/or the temperature at the location of second branch line 2201 in communication with second main line 2201.
FIG. 4A schematically illustrates a distribution diagram of a regulating component controlling coolant flow into different branch lines according to another embodiment of the disclosure.
As shown in fig. 4A, the regulating member 240 may include a temperature sensor 410 and at least one valve 420. The temperature sensor 410 is used to detect the temperature of the coolant at the communication of the at least one branch line and the second main line 230. At least one valve 420 is electrically connected to the temperature sensor 410, the at least one valve 420 being configured to control a flow of coolant into the at least one branch line in accordance with a signal from the temperature sensor 410.
For example, temperature sensor 410 is capable of detecting the temperature of the coolant at the communication of first branch line 2202 and second main line 230, and the temperature of the coolant at the communication of second branch line 2201 and second main line 230. In the case where the temperature of the coolant at the communication between any one of the branch lines and the second main line 230 is higher than the preset threshold, the valve 420 for controlling the flow rate of the coolant at the branch line may be rotated, for example, in the direction in which the coolant flows (for example, in fig. 4A, the direction indicated by the solid arrow), so that the opening at the communication between the branch line and the second main line 230 becomes large, thereby increasing the flow rate of the coolant. The preset threshold value may be set by a person skilled in the art according to actual use conditions.
For another example, temperature sensor 410 may also compare the temperature of the cooling fluid at the connection between first branch line 2202 and second main line 230 with the temperature of the cooling fluid at the connection between second branch line 2201 and second main line 230, obtain a comparison result, and send the comparison result to at least one valve 420. For example, the temperature sensor may send a high level to the valve corresponding to the branch line in which the temperature of the coolant is high, and send a low level to the valve corresponding to the branch line in which the temperature of the coolant is low. The valve 420 controls the distribution of the coolant flow into the different branch lines in response to the received level signal. Specifically, if the valve 420 receives a high level signal, it is rotated in the direction of the flow of the coolant (for example, in fig. 4A, the direction indicated by the solid arrow), so that the opening at the communication between the branch line and the second main line 230 becomes large, thereby increasing the flow rate of the coolant. If the valve 420 receives a low signal, it is rotated in the opposite direction to the flow of the coolant (for example, in fig. 4A, the direction indicated by the dotted arrow), so that the opening at the communication point of the branch line and the second main line 230 is reduced, thereby reducing the flow rate of the coolant.
FIG. 4B schematically illustrates a distribution diagram of a regulating component controlling coolant flow into different branch lines according to another embodiment of the disclosure.
As shown in fig. 4B, the regulating members 240 may be provided at the communication of each branch line with the second main line 230, and in case the temperature of the coolant at the communication is increased, the regulating members 240 are bent toward the direction in which the coolant flows.
As shown in fig. 4B, adjustment member 240 is disposed between first branch line 2202 and second branch line 2201, a first portion of adjustment member 240 is in contact with the cooling liquid in first branch line 2202, and a second portion of adjustment member 240 is in contact with the cooling liquid in second branch line 2201. In the case where the temperature of the coolant in the communication is increased, the regulating member 240 is bent toward the direction in which the coolant flows. When the temperature of the coolant in the first branch line 2202 increases, the first portion of the adjustment member 240 curves toward the direction in which the coolant flows (as in the direction indicated by the arrow in fig. 4B).
The plurality of branch pipes 220 hereinabove include first branch pipes 2202 and 2201, wherein each branch pipe dissipates heat, e.g., for a different functional component. The first branch pipe 2202 dissipates heat to the CPU0, and the second branch pipe 2201 dissipates heat to the CPU 1. However, it should be understood that the number of the branch pipes is merely an example, and the present disclosure does not limit the number of the branch pipes, nor does it limit the heat dissipation of each branch pipe to different functional components. For example, a plurality of branch lines may radiate heat to the same functional component, or a plurality of functional components may radiate heat via the same branch line.
Another aspect of the present disclosure provides an electronic apparatus including a plurality of functional parts and a heat sink for reducing temperatures of the plurality of functional parts. The heat dissipating double-fuselage includes: the device comprises a first main pipeline, a plurality of branch pipelines, a second main pipeline and a regulating component. Each branch pipeline of the plurality of branch pipelines is respectively communicated with the first main pipeline, so that the cooling liquid enters the plurality of branch pipelines through the first main pipeline. The second main pipeline is communicated with each branch pipeline, and the cooling liquid flows to the second main pipeline through each branch pipeline and flows out of the heat dissipation device from the second main pipeline so as to dissipate heat of a plurality of functional devices; and the adjusting component is used for controlling the distribution of the flow of the cooling liquid entering different branch pipelines according to the temperature of the cooling liquid at the communication part of at least one branch pipeline in the plurality of branch pipelines and the second main pipeline.
According to the embodiment of the present disclosure, for example, in the scenarios shown in fig. 2A and 2B, a closed cavity made of a heat conductive metal such as copper and aluminum is connected to the functional components in the electronic device, such as the CPU0 and the CPU1, and a partial region of the branch line is disposed in the closed cavity, so that the cooling of the branch line in the closed cavity takes away the heat of the functional components.
According to the embodiment of the present disclosure, heat of the plurality of functional components is transferred to the cooling liquid enclosed in the heat sink, and the heat is taken away by the cooling liquid, thereby reducing the temperature of the plurality of functional components.
According to an embodiment of the disclosure, the regulating member is located in the second main conduit, a first side of the regulating member is in communication with a first branch conduit of the plurality of branch conduits, a second side of the regulating member is in communication with a second branch conduit of the plurality of branch conduits, and the regulating member controls distribution of coolant flow into different branch conduits according to a temperature difference of the coolant in the first branch conduit and the coolant in the second branch conduit. Or the adjusting component controls the distribution of the flow of the cooling liquid entering different branch pipelines according to the temperature of the communication part of the first branch pipeline and the second main pipeline and/or the temperature of the communication part of the second branch pipeline and the second main pipeline.
According to an embodiment of the present disclosure, in a case where there is a temperature difference between the coolant in the first branch pipe and the coolant in the second branch pipe, the adjustment member is deformed according to the temperature difference to control the distribution of the flow rates of the coolant entering the first branch pipe and the second branch pipe by the deformation.
According to an embodiment of the present disclosure, the regulating member includes a structure made of a temperature sensitive material, which bends toward a side where a temperature of the coolant in the first branch pipe or the second branch pipe is lower in a case where there is a temperature difference between the coolant in the first branch pipe and the coolant in the second branch pipe.
According to the embodiment of the disclosure, the adjusting component comprises a blocking sheet made of temperature-sensitive materials, and the blocking sheet is placed between the communication position of the first branch pipeline and the second main pipeline and the communication position of the second branch pipeline and the second main pipeline.
According to an embodiment of the present disclosure, the adjusting means includes a moving means that moves, in a case where there is a temperature difference between the coolant in the first branch pipe and the coolant in the second branch pipe, so that the branch pipe flow rate at which the temperature of the coolant in the first branch pipe or the second branch pipe is lower is reduced.
