Description

BACKGROUND OF THE INVENTION 1. Field of the invention:

[0001] The present invention relates to the field of liquid cooling device technology, in particular an all-in-one liquid cooler for cooling and dissipating heat from a processor. 2. Description of the state of the art:

[0002] Liquid coolers used in computers and servers today are typically split coolers, consisting of a separate liquid cooling radiator, a cooling plate, and a liquid pump connected by multiple liquid lines to form a closed loop system. However, the split type is bulky and inconvenient to install. To address this, the inventor of this case proposed a variety of all-in-one liquid cooler designs. The all-in-one liquid cooler features a liquid pump inside a liquid cooling radiator and a cooling plate at the bottom. The cooling plate can be installed on a processor to function as a liquid-cooled processor.

[0003] However, the conventional design of liquid cooling radiators can result in uneven distribution of the coolant through the individual fluid lines, leading to inconsistent heat dissipation efficiency. If the coolant flow rate is higher in some fluid lines and lower in others, heat cannot be effectively dissipated, resulting in reduced heat dissipation efficiency in certain areas. This uneven circulation can lead to an unbalanced temperature distribution within the processor, negatively impacting its stability and performance.

[0004] If, however, the fluid flow rate is too high, the total volume of the cooler can be increased, but the fluid does not have sufficient residence time to effectively absorb heat as it flows through the heat dissipation tubes and the cooling plate. Consequently, the heat cannot be completely transferred to the coolant, resulting in insufficient overall heat dissipation. Ideally, an appropriate flow rate should be maintained so that the fluid has enough time to absorb the heat, but the flow rate is not so slow as to impair the coolant's circulation efficiency. Therefore, the question of how to improve upon the aforementioned shortcomings of the prior art is the subject of the present invention, which aims to actively overcome these deficiencies. SUMMARY OF THE INVENTION

[0005] The main objective of the present invention is to provide an all-in-one liquid cooler to solve the problems of uneven flow rate and excessive flow rate of the liquid in each heat dissipation tube of the conventional liquid cooler, so that the liquid can flow uniformly through each heat dissipation tube and completely dissipate the heat.

[0006] Another objective of the present invention is to provide an all-in-one liquid cooler to solve the problem of the hot liquid exiting the cooling plate being thermally transferred to the adjacent cold liquid, thereby ensuring that the cold liquid flows into the cooling plate at a low temperature.

[0007] To achieve the aforementioned objectives, the present invention proposes an all-in-one liquid cooler, the preferred technical solution of which comprises a liquid cooling radiator and a cooling plate. The liquid cooling radiator has a first liquid reservoir, a second liquid reservoir, and a heat dissipation tube assembly. The heat dissipation tube assembly has a plurality of first-row tubes, second-row tubes, and heat dissipation fins. The first-row and second-row tubes are flat metal tubes, both ends of which are connected to the first and second liquid reservoirs, respectively. The heat dissipation fins are arranged outside the first-row and second-row tubes, respectively.The top of the cooling plate is connected to the outer surface of the bottom wall of the first liquid reservoir, and the underside of the cooling plate is designed to adhere to the surface of a processor. The first liquid reservoir has a first reservoir body and a first reservoir lid. The top of the first reservoir body is concave to form a first chamber, and the interior of the first chamber is divided into a cold liquid chamber and a hot liquid chamber by a heat-resistant structure. The bottoms of the cold liquid chamber and the hot liquid chamber are each connected to the interior of the cooling plate via a cold liquid port and a hot liquid port, respectively.The first container lid covers the upper end of the first container body, and the upper wall of the first container lid is provided with a plurality of first-row tube insertion holes that connect to the cold liquid chamber and the hot liquid chamber. The lower ends of the first-row and second-row tubes are each inserted into the first-row tube insertion holes. A flow divider orifice is provided in the cold liquid chamber, which is provided with a plurality of through-holes connecting its two sides. The flow divider orifice allows the liquid flowing from the first row of tubes into the cold liquid chamber to be distributed through the plurality of through-holes and then flow through the cold liquid opening into the interior of the cooling plate.

[0008] The all-in-one liquid cooler of the present invention can achieve the following effects: (I) Slowing down the flow velocity of the coolant: The flow divider orifice has several through-holes that can slow down the velocity of the coolant flowing into the cooling plate. This helps to increase the residence time of the fluid in the first row of tubes, improve the heat exchange efficiency between the fluid and the heat dissipation fins, and ensure complete cooling of the fluid. (II) Uniform cooling: The flow divider orifice can help to distribute the fluid evenly in the first row of pipes, ensuring that the cold fluid can flow evenly through each first row of pipes, allowing the fluid to dissipate heat evenly, thus improving the overall heat dissipation efficiency. (III) Prevention of heat transfer from hot liquid to cold liquid: The design of the heat-resistant structure prevents the hot liquid flowing into the hot liquid chamber from transferring heat to the cold liquid in the adjacent cold liquid chamber, thus preventing the cooled cold liquid from being reheated.

[0009] With reference to Fig. 1 The present invention is an all-in-one liquid cooler, and a preferred embodiment thereof comprises a liquid cooling radiator 100, a cooling plate 200 and a liquid pump 300.

[0010] With reference to Fig. 2 and Fig. 3 the liquid cooling radiator 100 comprises a first liquid reservoir 10, a second liquid reservoir 20 and a heat dissipation pipe assembly 30.

[0011] The first fluid reservoir 10 and the second fluid reservoir 20 are hollow containers made of heat-dissipating metal (such as an aluminum alloy) and serve to inject a working fluid (water or another coolant) into the first fluid reservoir 10 and the second fluid reservoir 20. The heat dissipation tube assembly 30 comprises a plurality of first-row tubes 31, second-row tubes 32, and heat dissipation fins 33 arranged parallel and spaced apart. The first-row tubes 31 and the second-row tubes 32 are flat metal tubes, both ends of which are connected to the first fluid reservoir 10 and the second fluid reservoir 20, respectively. The heat dissipation fins 33 are arranged outside the first-row tubes 31 and the second-row tubes 32.

[0012] One side of the cooling plate 200 is connected to the outside of the bottom wall of the first liquid reservoir 10, so that the bottom wall of the first liquid reservoir 10 is directly connected to the cooling plate 200 via a connecting structure. The other side of the cooling plate 200 is used for mounting to a chip processor (not shown) to cool the chip processor. The liquid pump 300 is located in the second liquid reservoir 20 to circulate the working fluid in the liquid cooling radiator 100, so that it circulates sequentially between the first liquid reservoir 10, the second liquid reservoir 20, the heat dissipation tube assembly 30, and the cooling plate 200 (as shown in Figure 1). Fig. 4 shown).

[0013] With reference to the Fig. 5 and Fig. 6. In a preferred embodiment, the first liquid container 10 of the present invention comprises a first container body 11 and a first container lid 12. The first container body 11 is a container body formed by stamping an aluminum alloy, the upper end of which is concave to form a first chamber. The interior of the first chamber is divided by a heat-resistant structure 13 into a cold liquid chamber 14 and a hot liquid chamber 15. The bottom of the cold liquid chamber 14 and the bottom of the hot liquid chamber 15 are connected to the interior of the cooling plate 200 via a cold liquid opening 141 and a hot liquid opening 151, respectively (as shown in Figure 1). Fig. (4 shown). The first container lid 12 is a lid body formed by integral stamping from an aluminum alloy and covers the container opening at the upper end of the first container body 11 and is welded to it. The upper wall of the first container lid 12 is provided with a plurality of first row tube insertion holes 121, which are connected to the cold liquid chamber 14 and the hot liquid chamber 15, such that the lower ends of the first row tubes 31 and the second row tubes 32 can each be inserted into the first row tube insertion holes 121, so that one end (lower end) of each of the tubes of the first row 31 can be connected to the cold liquid chamber 14 and one end (lower end) of each of the tubes of the second row 32 can be connected to the hot liquid chamber 15.The present invention further provides a flow divider orifice 16 in the cold liquid chamber 14, wherein the flow divider orifice 16 is provided with a plurality of through-holes 164 connecting its two sides. Due to the arrangement of the flow divider orifice 16, the liquid (cold liquid) flowing from the first row of pipes 31 into the cold liquid chamber 14 first flows through the multiple through-holes 164 to complete the flow rate control, and then flows through the cold liquid hole 141 into the interior of the cooling plate 200.

[0014] With reference to Fig. 6 and Fig. 7 The flow divider orifice 16 is preferably an aluminum alloy plate formed by bending in one piece and comprises a first plate 161 corresponding to the first row-pipe inlet holes 121 of the first container lid 12, a second plate 162 connected to one end of the first plate 161, and a third plate 163 connected to the other end of the first plate 161. The bending directions and angles of the second plate 162 and the third plate 163 can be adapted according to the interior of the first container body 11 and are not limited. In one of the preferred embodiments, the second plate 162 is connected to and attached to one side of the heat-resistant structure 13, and the end of the third plate 163 is connected to and attached to the inner surface of the first container lid 12 (e.g., welded to it). Fig. 4) Thus, several through-holes 164 are provided on the first plate 161, such that most of the through-holes 164 correspond to the inlet holes 121 of the first row of pipes (one end of the pipes 31 of the first row). The arrangement and range of the multiple through-holes 164 can be modified according to the required regulation of the water flow. The multiple through-holes 164 can also be arranged on the second plate 162 or the third plate 163. The second plate 162 on one side of the flow divider orifice 16 can be welded to one side of the heat-resistant structure 13 by a welded construction, the welding process being CAB furnace brazing or aluminum alloy vacuum chamber welding. Alternatively, as shown in Fig. 6 and Fig. As shown in Figure 7, two positioning holes 165 are provided on one side of the second plate 162 corresponding to the heat-resistant structure 13, and two positioning projections 133 can be provided on one side of the heat-resistant structure 13. During assembly, the positioning projections 133 are embedded in the positioning holes 165, thereby fixing the flow divider orifice 16 to one side of the heat-resistant structure 13. If necessary, welding can also be carried out using the welding method described above.

[0015] With reference to the Fig. 4, Fig. 5 and Fig. 6 The heat-resistant structure 13 preferably comprises a cold liquid baffle plate 131 and a hot liquid baffle plate 132. The cold liquid baffle plate 131 and the hot liquid baffle plate 132 are arranged parallel and spaced apart from each other in the first chamber of the first container body 11 to divide the first chamber into the cold liquid chamber 14 and the hot liquid chamber 15. Furthermore, the edges of the cold liquid baffle plate 131 and the hot liquid baffle plate 132 are welded to the inner wall of the first chamber and the inner wall of the first container lid 12 by the welding process described above. This allows the second plate 162 of the flow divider orifice plate 16 to be connected to and attached to one side of the cold liquid baffle plate 131 by the assembly or welding structure described above.

[0016] The present invention, through the aforementioned design, utilizes the multiple through-holes 164 of the flow divider orifice 16 to control the flow velocity of the liquid (cooling fluid) flowing into the cooling plate 200. Controlling the flow rate in this way extends the residence time of the liquid in the tubes 31 of the first row and improves the heat exchange efficiency between the liquid and the heat dissipation fins 33, ensuring that the liquid is completely cooled and thus enhancing the cooling effect on the processor. Furthermore, the flow divider orifice 16 helps to distribute the liquid evenly within the tubes 31 of the first row, ensuring that the liquid (cooling fluid) flows uniformly through each tube 31 of the first row.By controlling the uniform flow of the liquid, it is possible to prevent the liquid from flowing too quickly in a particular tube of the series, thus ensuring that the liquid can dissipate heat evenly and thereby improving the overall heat dissipation efficiency. Furthermore, the present invention, through the design of the heat-resistant structure 13, forms a heat-resistant space between the cold liquid baffle plate 131 and the hot liquid baffle plate 132. This prevents the hot liquid flowing into the hot liquid chamber 15 from thermally transferring to the cold liquid in the adjacent cold liquid chamber 14, thus preventing the cooled cold liquid from being reheated and improving the cooling performance of the cooling plate.

[0017] Referring to the Fig.According to figures 2 to 4 and 8, the second liquid container 20 of the present invention can preferably be configured as a structure for mounting the liquid pump 300, comprising a second container body 21, a second partition 22, and a second container lid 23. The upper end of the second container body 21 is concave to form a second chamber. The second partition 22 is arranged within the second chamber to divide the second chamber into a liquid outlet chamber 24 and a liquid inlet chamber 25.The bottom wall of the second container body 21 is provided with a plurality of second row-pipe insertion holes 211, which are connected to the liquid outlet chamber 24 and the liquid inlet chamber 25, and the upper ends of the first row pipes 31 and the second row pipes 32 are each inserted into the second row-pipe insertion holes 211, so that the upper ends of the pipes of the first row 31 and the pipes of the second row 32 are each connected to the liquid outlet chamber 24 and the liquid inlet chamber 25. The second container cover 23 covers the container opening at the upper end of the second container body 21. The second container cover 23 is provided with a seat body that projects into the liquid inlet chamber 25, and a liquid pump installation chamber 26 is formed in the seat body.The liquid pump mounting chamber 26 is provided with a liquid inlet opening 261, which is connected to the liquid inlet chamber 25, and a liquid outlet opening 262, which is connected to the liquid outlet chamber 24. The liquid pump 300 is a known component. The liquid pump 300 is installed in the liquid pump mounting chamber 26 such that it is located in the liquid inlet chamber 25 of the second liquid reservoir 20 and can pump liquid for circulation, thereby forming an all-in-one liquid cooler that includes the liquid pump 300.

[0018] Although a particular embodiment of the invention has been described in detail for illustrative purposes, various modifications and improvements can be made without departing from the spirit and scope of the invention. Accordingly, the invention is limited only by the appended claims.
