Description

Technical Field

[0001] The present invention relates to radiator technology, and in particular to an improved liquid cooling head, a liquid cooling head assembly and a liquid cooling radiator. Background Art

[0002] At present, the radiator used for heat dissipation of computer internal parts is generally a liquid-cooled radiator. Liquid-cooled radiators use liquid to circulate under the drive of a pump to remove the heat from the radiator. Compared with air cooling, they have the advantages of being quiet, stable in cooling, and less dependent on the environment. The heat dissipation performance of a liquid-cooled radiator is proportional to the flow rate of the cooling liquid (liquid or other liquid), and the flow rate of the cooling liquid is related to the power of the liquid pump of the refrigeration system. In addition, the heat capacity of the liquid is large, which makes the liquid-cooled refrigeration system have a good heat load capacity.

[0003] A liquid-cooled radiator is usually composed of a liquid-cooling row, a liquid-cooling head and a liquid pipe. The liquid pipe is connected between the liquid-cooling row and the liquid-cooling head. The liquid-cooling head includes a shell, a pump installed inside the shell, and a liquid inlet and a liquid outlet located on the surface of the shell. In actual application, it still has some shortcomings, such as: 1. The weight of the entire liquid-cooling head is relatively large. When it is installed on a heat-generating component, the required snap-on pressure is large, the installation operation is laborious and time-consuming, and it is prone to shaking after installation; 2. The volume of the entire liquid-cooling head is relatively large, and it needs to be installed corresponding to the heat-generating component, which occupies a large space and is not conducive to the internal space design of computer products; 3. Usually, one liquid-cooling row corresponds to one liquid-cooling head, which is difficult to meet the layout requirements of multiple liquid-cooling heads for one liquid-cooling row.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0040] Liquid collecting box 1, heat conducting sheet 2, liquid inlet 11, first liquid outlet 12, second liquid outlet 13, diversion channel 14, first diversion port 15, second diversion port 16, liquid isolating cover 3, first sealing ring 4, second sealing ring 5, liquid isolating sheet 6, LED light board 7, upper cover 8, first liquid cooling head 100, second liquid cooling head 200, liquid cooling row 300, pump 400, liquid inlet pipe 501, first liquid outlet pipe 502, second liquid outlet pipe 503, three-way joint 504, total liquid outlet pipe 505. DETAILED DESCRIPTION

[0041] Please refer to Figures 1 to 13 As shown, it shows the specific structure of various embodiments of the present invention.

[0042] First, please refer to Figures 1 to 7 As shown, an improved liquid cooling head is described in detail, which includes a liquid collecting box 1 and a heat conducting sheet 2; wherein:

[0043] The liquid collecting box 1 has a liquid inlet 11, a first liquid outlet 12, a second liquid outlet 13 and a diverter channel 14 located inside the liquid collecting box 1; the liquid inlet end of the diverter channel 14 is connected to the liquid inlet 11, and the liquid outlet end of the diverter channel 14 is respectively provided with a first diverter port 15 and a second diverter port 16, and the first diverter port 15 and the second diverter port 16 are both smaller than the liquid inlet 11 and the diverter channel 14;

[0044] The heat conducting sheet 2 is sealed and fixed to the liquid collecting box 1 and forms a closed accommodating cavity therewith. The heat conducting sheet 2 is integrally formed with a plurality of fin portions located in the accommodating cavity. During manufacturing, the heat conducting sheet 2 and the fin portions are integrally formed.

[0045] The first flow diversion port 15 is connected to the first liquid outlet 12 through the accommodating chamber, and the second flow diversion port 16 is connected to the second liquid outlet 13; the liquid enters the flow diversion channel 14 through the liquid inlet 11, a part of the liquid enters the accommodating chamber through the first flow diversion port 15 and flows out from the first liquid outlet 12 after heat exchange with the fin part, and the other part of the liquid flows in through the second flow diversion port 16 and flows out from the second liquid outlet 13. Preferably, the liquid inlet 11 and the first liquid outlet 12 are arranged on one side of the liquid collecting box 1, and the second liquid outlet 13 is arranged on the other side of the liquid collecting box 1.

[0046] Specifically, the liquid inlet 11 and the second diversion port 16 are respectively located opposite to the two ends of the diversion channel 14, and the first diversion port 15 is located between the two ends of the diversion channel 14; the second diversion port 16 is connected to the diversion channel 14 through a transition channel that is gradually reduced in the conveying direction, so that a certain resistance is formed when the liquid is diverted toward the second diversion port 16. In this way, the liquid can be diverted relatively well, avoiding the situation where a large amount of liquid is conveyed from the first diversion port 15 or the second diversion port 16, while taking into account the conveying volume of the first diversion port 15 and the second diversion port 16. Figure 7 It can be seen that the liquid inlet 11 and the liquid inlet end of the diversion channel 14 are also connected through a transition channel designed to gradually decrease along the conveying direction, so that the liquid entering the liquid collecting box 1 is gathered and the pressure is increased.

[0047] Combination Figures 4 to 7 ,as well as Fig.11As shown, a liquid isolating cover 3 covering the fin part is provided in the accommodating chamber, the liquid isolating cover 3 divides the accommodating chamber into a first liquid inlet chamber and a first liquid outlet chamber, the first diversion port 15 is connected to the first liquid inlet chamber, the liquid isolating cover 3 is provided with a first slot hole connecting the first liquid inlet chamber and the interior of the liquid isolating cover 3, the peripheral side surface of the liquid isolating cover 3 is provided with a second slot hole connecting the first liquid outlet chamber and the interior of the liquid isolating cover 3, and the first liquid outlet chamber is connected to the first liquid outlet port 12; in this way, after the cold liquid enters the interior of the liquid isolating cover 3 from the first slot hole, it is evenly distributed on the fin part with sufficient contact, and then flows out from the second slot hole, so that the cold liquid is effectively drained to avoid mixing of the cold liquid and the hot liquid, thereby making full use of the cold liquid to absorb heat and greatly improving the heat dissipation effect.

[0048] In this embodiment, the heat conductive sheet 2 has a square profile and is made of copper or aluminum. The heat conductive sheet 2 made of copper has a better heat dissipation effect and its bottom surface is a plane. In addition, the heat conductive sheet 2 is fixed to the bottom of the liquid collecting box 1 by multiple screws (not shown in the figure). The periphery of the heat conductive sheet 2 is provided with multiple fixing holes, and the periphery of the bottom of the liquid collecting box 1 is provided with multiple screw holes. The multiple screws pass through the corresponding fixing holes and are screwed and fixedly connected with the corresponding screw holes.

[0049] The liquid isolating cover 3 is made of metal or plastic material and is square in shape. A groove is concavely arranged in the center of the surface of the liquid isolating cover 3, and a plurality of first slots are arranged at intervals on the bottom surface of the groove, so that the cold liquid entering the liquid isolating cover 3 is more evenly distributed on the fin part, and the cold liquid is more effectively utilized to improve the heat dissipation effect. A first sealing ring 4 is sandwiched between the heat conducting sheet 2 and the liquid collecting box 1, and a second sealing ring 5 is sandwiched between the upper surface periphery of the liquid isolating cover 3 and the liquid collecting box 1. In addition, the first sealing ring 4 is square in shape, and the second sealing ring 5 is circular in shape. In actual design and production, by adjusting the installation position of the liquid isolating cover 3, the position of the second slot can be made as low as possible, that is, the position of the liquid outlet through the second slot is as low as possible, so as to improve the heat dissipation effect.

[0050] like Figure 2 As shown, as an alternative, a liquid partition plate 6 covering the fin part can also be provided in the accommodating chamber, and the liquid partition plate 6 divides the accommodating chamber into a second liquid inlet chamber and a second liquid outlet chamber, and the first diversion port 15 is connected to the second liquid inlet chamber, and the liquid partition plate 6 is provided with a third slot hole connecting the second liquid inlet chamber and the area where the fin part is located, and the second liquid outlet chamber is connected to the first liquid outlet port 12.

[0051] like Figure 3 and Figure 4 As shown, an LED light board 7 may be provided on the top of the liquid collecting box 1, and an upper cover 8 may be provided on the LED light board 7, and the surface of the upper cover 8 may be selectively decorated. Figure 1 and Figure 3It can be seen that, in comparison, after the LED light board 7, the upper cover 8 and other components are arranged on the top of the liquid collecting box 1, the overall height dimension is slightly larger. However, compared with the liquid cooling head with a built-in pump in the conventional technology, the overall height dimension of the liquid cooling head of the present invention is greatly reduced.

[0052] like Figures 8 to 13 As shown, a liquid cooling head assembly is provided, including a first liquid cooling head 100 and a second liquid cooling head 200; the first liquid cooling head 100 is the aforementioned improved liquid cooling head; the second liquid cooling head 200 has a liquid inlet connection end and a liquid outlet connection end, and the second liquid outlet 13 of the first liquid cooling head 100 is connected to the liquid inlet connection end of the second liquid cooling head 200. The liquid inlet 11 of the first liquid cooling head 100 is connected to a liquid inlet pipe, the first liquid outlet 12 of the first liquid cooling head 100 is connected to a first liquid outlet pipe, the liquid outlet connection end of the second liquid cooling head 200 is connected to a second liquid outlet pipe, and the first liquid outlet pipe and the second liquid outlet pipe are collectively connected to a total liquid outlet pipe.

[0053] The first liquid cooling head 100 may be provided with one or more first liquid cooling heads 100. When the first liquid cooling heads 100 are provided with more than one, adjacent first liquid cooling heads 100 are connected to the liquid inlet 11 of the next first liquid cooling head 100 through the second liquid outlet 13 of the previous first liquid cooling head 100.

[0054] Next, a liquid cooling radiator is provided, including a liquid cooling row 300, a liquid cooling head and a connecting liquid pipe connected between the liquid cooling row 300 and the liquid cooling head, and a pump for driving liquid circulation; the liquid cooling head includes the aforementioned improved liquid cooling head, and the pump is arranged outside the liquid cooling head. The pump 400 is arranged flexibly and freely, and can be placed anywhere, for example: the liquid cooling row 300, the connecting liquid pipe, etc. The liquid cooling head assembly can be applied to the liquid cooling radiator.

[0055] Combination Figure 8 and Fig.11 As shown, the working principle of the liquid cooling radiator is introduced as follows:

[0056] When in use, the heat conducting plates 2 of the first liquid cooling head 100 and the second liquid cooling head 200 are respectively attached and fixed to the heating element, and the liquid of the liquid cooling row 300 enters the diversion channel 14 from the liquid inlet pipe 501 through the liquid inlet port 11 of the first liquid cooling head 100, and a part of the liquid enters the accommodating cavity through the first diversion port 15 and exchanges heat with the fin part, and then flows out from the first liquid outlet 12 through the first liquid outlet pipe 502, and the other part of the liquid flows in through the second diversion port 16, flows out from the second liquid outlet 13 and enters the second liquid cooling head 200, and then flows out through the second liquid outlet pipe 503 of the second liquid cooling head 200, and the first liquid outlet pipe 502 and the second liquid outlet pipe 503 are connected to the main liquid outlet pipe 505 through the three-way joint 504, and enter the liquid cooling row 300 for cooling so as to be recycled.

[0057] The design focus of the present invention is that it mainly adopts the structural design of the improved liquid cooling head, and the first and second diversion ports are respectively provided at the liquid outlet end through the diversion channel. After the liquid enters the diversion channel through the liquid inlet, a part of the liquid enters the accommodating cavity through the first diversion port and exchanges heat with the fin part and then flows out from the first liquid outlet, and the other part of the liquid flows out from the second liquid outlet through the second diversion port; in this way, a plurality of liquid cooling heads can be freely connected to meet the need to arrange a plurality of liquid cooling heads for heat dissipation;

[0058] In addition, setting the pump on the outside of the liquid cooling head solves the problem of heavy weight of the liquid cooling head and shaking during pump transmission in traditional technology. At the same time, the overall height of the liquid cooling head is reduced, and the space occupied is small, which is beneficial to the internal space design of computer products. On the other hand, the setting of the pump also becomes more flexible and free, and can be placed anywhere, such as: liquid cooling radiator, connecting liquid pipe, etc.

[0059] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
