In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Furthermore, in the following detailed description of the present application, certain specific details are set forth in order to provide a better understanding of the present application. It will be apparent to one skilled in the art that the present application may be practiced without these specific details.

The embodiment of the application relates to a heat dissipation device, and the heat dissipation pipeline that this heat dissipation device set up includes that it is followed first direction and run through the heating panel and wherein one end is by feed liquor pipe and the fluid-discharge tube of shutoff to and many are followed the second direction and run through the heating panel and both ends all by the connecting pipe of shutoff, and the both ends of many connecting pipes are linked together with feed liquor pipe and fluid-discharge tube respectively. Through the arrangement, the heat dissipation efficiency can be improved while the heat dissipation effect of the heat dissipation device is ensured, and the temperature difference between the liquid flowing in from the liquid inlet and the liquid flowing out from the liquid outlet is reduced, so that the liquid flowing out from the liquid outlet can be directly used for heating, and the liquid can be directly used for heat dissipation again after heating, the cyclic utilization of the liquid is realized, and the heat energy dissipated by the equipment to be dissipated is recycled; meanwhile, the heat dissipation pipeline can be simply and efficiently processed in the heat dissipation plate, and the process difficulty of production and manufacturing is reduced. The heat dissipation device can be applied to heat dissipation of electronic products or devices such as chip boards, CPUs, GPUs and ASICs of servers.

Fig. 1 is a schematic structural view of a heat dissipation pipe of a heat dissipation device according to some embodiments of the present disclosure, and fig. 2 is a schematic perspective structural view of the heat dissipation device according to some embodiments of the present disclosure. As shown in fig. 1 and 2, the heat dissipation apparatus 100 includes a heat dissipation plate 10, and a heat dissipation pipeline is disposed in the heat dissipation plate 10, and the heat dissipation pipeline includes a liquid inlet pipe 11, a liquid outlet pipe 12, and a plurality of connection pipes 13. The liquid inlet pipe 11 and the liquid outlet pipe 12 penetrate through the heat dissipation plate 10 along the first direction and one end of the heat dissipation plate is blocked, the plurality of connecting pipes 13 penetrate through the heat dissipation plate 10 along the second direction and two ends of the heat dissipation plate are blocked, and the plurality of connecting pipes 13 are arranged at intervals along the first direction. The first and second directions have been shown in fig. 1. The two ends of the connecting pipes 13 are respectively communicated with the liquid inlet pipe 11 and the liquid outlet pipe 12. The arrows in the heat dissipation pipeline of fig. 1 show the flow direction of the liquid, which can flow in from one end of the liquid inlet pipe 11, flow through the liquid inlet pipe 11, the connecting pipe 13, and the liquid discharge pipe 12 in this order, and flow out from one end of the liquid discharge pipe 12. Those skilled in the art can determine the specific number and length of the connecting pipes 13 and the spacing distance between two adjacent connecting pipes 13, and determine the lengths of the liquid inlet pipe 11 and the liquid outlet pipe 12 and the positions of the liquid inlet pipe 11 and the liquid outlet pipe 12 relative to the heat dissipating plate 10, respectively, according to the actual working conditions (such as the thickness of the heat dissipating plate 10, the length of the heat dissipating plate 10 in the first direction, the heat dissipating capacity of the device to be dissipated, and the like). For example only, when the heat dissipation amount of the device to be dissipated is large, the number of the connection pipes 13 may be set to be large and the interval distance between two adjacent connection pipes 13 may be set to be short. In some embodiments, the plurality of connection pipes 13 may be arranged in parallel and equally spaced from each other. The heat sink 10 may be made of a material that easily conducts heat, such as copper or aluminum. The liquid may be a coolant for absorbing heat of the device to be cooled, and the liquid may be water, antifreeze, or other liquid for absorbing heat.

The heat dissipation device 100 of the embodiment of the present application has high heat dissipation efficiency, and thus the temperature difference between the liquid flowing in from the liquid inlet of the heat dissipation device 100 and the liquid flowing out from the liquid outlet of the heat dissipation device 100 is small. Firstly, the liquid flowing out of the liquid outlet of the heat radiator can be used for direct heating, and the heated liquid can be returned to the heat radiator again for heat radiation, so that the cyclic utilization of the liquid is realized.

In some embodiments, the first direction is perpendicular to the second direction. In other embodiments, the angle between the first direction and the second direction may be other angles, such as 60 °, 75 °, 85 °, and the like. In some embodiments, as shown in fig. 1 and 2, the first direction is perpendicular to the second direction, and the heat dissipation plate 10 has a rectangular shape. The liquid inlet pipe 11 and the liquid outlet pipe 12 are both parallel to the short side of the heat dissipation plate 10, and the plurality of connecting pipes 13 are parallel to the long side of the heat dissipation plate 10. In other embodiments, the heat dissipation plate 10 may also be circular, triangular, polygonal, etc. The shape of the heat dissipation plate 10 is preferably completely or partially the same as that of the device 200 to be heat dissipated, so that the heat dissipation plate 10 can achieve a better heat dissipation effect while saving the cost of the heat dissipation plate 10.

In some embodiments, liquid inlet pipe 11, liquid outlet pipe 12, and connecting pipe 13 may be plugged in a variety of ways. In some embodiments, one end of each of liquid inlet pipe 11 and liquid outlet pipe 12 and both ends of the plurality of connecting pipes 13 are sealed by a sealing member, and the sealing member is in threaded connection with liquid inlet pipe 11, liquid outlet pipe 12 or the plurality of connecting pipes 13. In some embodiments, the occluding member may be a screw. The plugging member is in threaded connection with the liquid inlet pipe 11, the liquid discharge pipe 12 or the plurality of connecting pipes 13, so that the plugging effect of the plugging member can be ensured, liquid is effectively prevented from leaking from the plugging member, and the threaded connection structure is convenient to mount and dismount. In some alternative embodiments, the blocking member may be connected to the liquid inlet pipe 11, the liquid outlet pipe 12 or the plurality of connecting pipes 13 by bonding, welding, or clipping. For example, as shown in fig. 1, the blocking member that blocks the liquid inlet pipe 11, the liquid outlet pipe 12, and the plurality of connection pipes 13 may be a blocking plate connected to the heat radiating plate 10. In some embodiments, a leakage-proof gasket may be provided between the blocking member and the heat dissipation plate 10 to further prevent liquid from leaking out of the blocking member. The leakage-proof gasket can be made of rubber, latex or resin.

In some embodiments, the end of liquid inlet pipe 11 that is not blocked (i.e., liquid inlet) and the end of liquid outlet pipe 12 that is not blocked (i.e., liquid outlet) are located on opposite sides of heat sink 10. Therefore, all the heat dissipation pipelines can be fully utilized, so as to improve the heat dissipation effect of the heat dissipation device 100 on the equipment 200 to be dissipated. For example only, when heat dissipating plate 10 is rectangular, the end of inlet pipe 11 that is not plugged and the end of outlet pipe 12 that is not plugged are located on opposite sides of the rectangle. For another example, when the heat dissipating plate 10 is circular, the end of the liquid inlet pipe 11 that is not sealed and the end of the liquid outlet pipe 12 that is not sealed may be located at positions symmetrical with respect to the center of the circle. In alternative embodiments, the liquid inlet and the liquid outlet may also be located on the same side or adjacent sides of the heat sink 10.

In some embodiments, the cross-sections of liquid inlet pipe 11, liquid outlet pipe 12 and connecting pipe 13 are circular or elliptical. In other embodiments, the cross-sections of the liquid inlet pipe 11, the liquid outlet pipe 12 and the connecting pipe 13 may be polygonal (e.g., quadrilateral, hexagonal, octagonal, etc.). Compared with the polygonal pipeline with the cross section of the liquid inlet pipe 11, the liquid outlet pipe 12 and the connecting pipe 13, impurities are not easy to accumulate in the pipeline with the circular or elliptical cross section, and the heat dissipation pipeline can be effectively prevented from being blocked. In addition, the pipeline with the circular section is more convenient to produce and manufacture.

In some embodiments, the heat dissipation device 100 includes two heat dissipation plates 10. Fig. 3 is a schematic structural view of two heat dissipation plates and a device to be dissipated according to some embodiments of the present application, and as shown in fig. 3, a device to be dissipated 200 is disposed between the two heat dissipation plates 10. For example only, when the device to be heat-dissipated 200 is a chip, the heat dissipation plates 10 are respectively disposed on two side surfaces of the chip, and the surfaces of the heat dissipation plates 10 are attached to the surfaces of the chip. This can ensure the heat dissipation effect of the heat dissipation apparatus 100 on the device to be dissipated. The device to be heat-dissipated 200 shown in fig. 3 may be a chip, a chip aggregate, or a pcb board or the like.

In other embodiments, the heat dissipation device 100 includes a plurality of heat dissipation plates 10, for example, the heat dissipation device 100 may include 3, 5, 6, etc. heat dissipation plates 10. The number of the heat dissipation plates 10 in the heat dissipation device 100 may be determined by those skilled in the art specifically according to the structure, size, number, etc. of the devices 100 to be heat dissipated. Fig. 4 is a schematic structural diagram of a plurality of heat dissipation plates 10 and a device 200 to be dissipated according to some embodiments of the present application, as shown in fig. 4, the plurality of heat dissipation plates 10 are fixedly connected by a through connection rod (not shown), and the device 200 to be dissipated is disposed between every two adjacent heat dissipation plates 10. Thus, the number of the heat dissipation plates 10 can be reduced on the basis of ensuring the heat dissipation effect of the heat dissipation device 100 on the device 200 to be dissipated, so that the heat dissipation plates 10 can be fully utilized. In some embodiments, the connecting rod may be a threaded rod, and the plurality of heat dissipation plates 10 may be fixedly connected by connecting nuts at both ends or one end of the connecting rod. The heat dissipating plate 10 between two adjacent connecting pipes 13 is provided with a mounting hole penetrating through the heat dissipating plate 10 in the thickness direction, and the connecting rod can pass through the mounting hole. The device to be heat-dissipated 200 shown in fig. 4 may be a chip, a chip aggregate, or a pcb board or the like.

The heat dissipation device disclosed in the present application may bring about beneficial effects including, but not limited to: (1) the heat dissipation efficiency is improved while the heat dissipation effect is ensured, so that the temperature difference between liquid flowing in from the liquid inlet of the heat dissipation device and liquid flowing out from the liquid outlet of the heat dissipation device is reduced, the liquid discharged by the heat dissipation device can be directly applied to heating without treatment, the heated liquid can return to the heat dissipation device again and be directly used for heat dissipation, and the cyclic utilization of the liquid is realized; (2) the heat dissipation efficiency is high, and the heat dissipation device can be applied to heat dissipation of high-power equipment to be dissipated (such as a high-power chip); (3) due to the structural arrangement of the heat dissipation pipeline, the heat dissipation pipeline is processed on the heat dissipation plate simply and efficiently, and the process difficulty is reduced; (4) the resistance of the heat dissipation pipeline is small, the heat dissipation pipeline is not easy to block, the flow of liquid in the heat dissipation pipeline is large, and the requirement on the water quality of the liquid is low; (5) the recycling of the heat energy emitted by the equipment to be radiated is realized. It is to be noted that different embodiments may produce different advantages, and in different embodiments, any one or combination of the above advantages may be produced, or any other advantages may be obtained.

Some embodiments of the present application provide a thermal dissipation heating system 1000. The heat-radiating heating system 1000 includes the heat radiator 100 according to any one of the above embodiments. By using the heat dissipation device 100 according to any of the above technical solutions, when the equipment 200 to be cooled is cooled, because the temperature difference between the liquid flowing in from the liquid inlet of the heat dissipation device 100 and the liquid flowing out from the liquid outlet of the heat dissipation device 100 is small, the heat dissipation and heating system can directly use the liquid after the heat dissipation device 100 absorbs the heat of the equipment 200 to be cooled for heating, and can directly use the liquid after heating for cooling. In addition, because the heat sink 100 has low requirements for the water quality of the liquid, a water purifying device is not required to be arranged in the heat dissipation and heating system 1000, and the cost of the heat dissipation and heating system 1000 is reduced.

FIG. 5 is a schematic diagram of a thermal dissipation heating system according to some embodiments of the present application. As shown in fig. 5, in some embodiments, the heat-radiating heating system 1000 may include a device to be radiated 200 and a heating device 300; the heat sink 100 is disposed adjacent to the apparatus 200 to be heat-dissipated, so that the liquid flowing through the heat sink 100 can absorb the heat emitted from the apparatus 200 to be heat-dissipated. The liquid outlet of the heat sink 100 is connected to the inlet of the heating device 300, and the liquid inlet of the heat sink 100 is connected to the outlet of the heating device 300. The heating apparatus 300 may be understood as a heating facility (e.g., a radiator) provided to maintain a space where people live or produce in a suitable thermal state. The direction of flow of the liquid in the radiant heating system 1000 is shown by the arrows in fig. 5. The liquid having a higher temperature may be introduced into the pipe of the heating apparatus 300, and the liquid releases heat in the pipe to increase the temperature of the area to be heated by the heating apparatus 300. The heating equipment 300 is used in cooperation with the heat dissipation device 100, and the liquid flowing out of the liquid outlet of the heat dissipation device can be used for heating of the heating equipment 300, so that the cyclic utilization of the liquid is realized, and the recycling of the heat energy emitted by the equipment 200 to be dissipated is also realized.

In some embodiments, if a heat sink is used that has only one conduit for fluid flow, the temperature difference between the fluid entering the heat sink from the inlet port and the fluid exiting the heat sink from the outlet port may be large (e.g., up to 20 ℃, 25 ℃, or even 40 ℃, etc.). In the present application, the heat dissipation pipeline is provided according to any of the above technical solutions of the embodiments of the present application, so that while the heat dissipation effect of the heat dissipation device 100 on the device 200 to be dissipated is ensured, the temperature difference between the liquid flowing in from the liquid inlet of the heat dissipation device 100 and the liquid flowing out from the liquid outlet of the heat dissipation device 100 is small (for example, the temperature difference is 2 ℃, 5 ℃, 8 ℃, etc.). If the temperature difference between the liquid flowing from the liquid inlet of the heat sink 100 and the liquid flowing from the liquid outlet of the heat sink 100 is too large, the heat sink 100 and the heating device 300 cannot be directly connected to realize the recycling of the liquid. Since if the temperature of the liquid flowing out from the liquid outlet of the heat sink 100 is high, even if the temperature of the liquid in the heating equipment 300 is lowered, the temperature of the liquid flowing out from the heating equipment 300 after being supplied to the heating equipment 300 may still be high, and the liquid cannot dissipate heat of the equipment 200 to be cooled, so that the liquid cannot be recycled. Therefore, by using the heat sink 100 according to the embodiment of the present application, since the temperature difference between the liquid flowing in from the liquid inlet of the heat sink 100 and the liquid flowing out from the liquid outlet of the heat sink 100 is small, the liquid flowing out from the heating equipment 300 can be directly used for heat dissipation of the heat sink 100, and therefore the heat sink 100 and the heating equipment 300 can be directly connected to each other to realize recycling of the liquid, the heat dissipation and heating system 1000 has a simple structure, and heat energy can be effectively recycled.

In some embodiments, the cross-sectional area and the length of the plurality of connection pipes 13 disposed in the heat dissipation device 100 are within a preset range, so that the temperature difference between the liquid flowing in from the liquid inlet of the heat dissipation device 100 and the liquid flowing out from the liquid outlet of the heat dissipation device 100 is less than a set threshold value. By adjusting the cross-sectional area and length of the connection pipe 13, the temperature difference between the liquid flowing in from the liquid inlet of the heat sink 100 and the liquid flowing out from the liquid outlet of the heat sink 100 can be adjusted. In some embodiments, the cross section of the connecting pipe 13 can be understood as the cross section of a single connecting pipe, and the temperature difference can be adjusted by adjusting the number of the connecting pipes 13. In some embodiments, the cross-section of the connecting tube 13 may be understood as a combination of the cross-sections of a plurality of connecting tubes 13. In some embodiments, the set threshold for the temperature difference may be 2 ℃, 3 ℃, 5 ℃, 8 ℃, etc. In some embodiments, for a specific device 100 to be cooled and a specific liquid temperature and liquid flow rate (e.g., the liquid temperature and the liquid flow rate flowing into the heat sink 100 from the liquid inlet), the corresponding relationship between the cross-sectional area and the length of the connecting pipe 13 and the temperature difference may be determined through theoretical calculation or experimental manner, and the preset range of the cross-sectional area and the length of the corresponding connecting pipe may be selected according to the set threshold of the temperature difference. The connection pipes of a certain thickness, number and length can then be selected such that the cross-sectional area and length of the plurality of connection pipes 13 are within the preset range.

In this embodiment, when the heat sink 100 is used with different heating devices 300, the temperature difference between the liquid flowing in from the liquid inlet of the heat sink 100 and the liquid flowing out from the liquid outlet of the heat sink 100 can be adjusted by adjusting the cross-sectional area and the length of the connecting pipe 13, so that the heat sink 100 can be used with different heating devices 300 in different heat-dissipating heating systems 100, thereby improving the general adaptability of the heat sink 100 in use.
