Description

Technical Field

[0001] This application relates to a heat dissipation device, and more particularly to a liquid cooling heat dissipation device. Prior Technology

[0002] A conventional liquid cooling system mainly includes a radiator, a water block, a water pump, and two water tanks. The radiator has a fluid tube assembly, and the two water tanks are respectively connected to the two ends of the fluid tube assembly. The water block is connected to either water tank by two water pipes, and the water pump is connected to one of the water pipes.

[0003] While conventional liquid cooling devices provide the necessary heat dissipation, the two-pipe wiring method limits the configuration to either of the two water tanks at either end of the radiator. This restricts the wiring options and limits the variety of choices available to users, which in turn affects their willingness to purchase.

[0004] Therefore, how to improve upon the shortcomings of the aforementioned prior technologies is a major issue that the creator of this application urgently needs to address. Summary of the Invention

[0005] The purpose of this application is to provide a liquid cooling heat dissipation device, mainly by allowing for diverse positional options for the first and second interfaces used to connect the water cooling head.

[0006] To achieve the above objectives, this application provides a liquid cooling heat dissipation device, comprising: a water cooling radiator with a window and including a fluid pipe assembly, the fluid pipe assembly including a plurality of first fluid pipes and a plurality of second fluid pipes; a water tank structure including a first water tank and a second water tank; a flow guiding structure embedded in the window and connected and communicating between one end of each of the first fluid pipes and one end of each of the second fluid pipes, the other ends of each of the first fluid pipes and the other ends of each of the second fluid pipes being respectively connected and communicating with the first water tank and the second water tank, the flow guiding structure having a first chamber and a second chamber separated from each other and having a first interface and a second interface respectively communicating with the first chamber and the second chamber, one end of each of the first fluid pipes and one end of each of the second fluid pipes being respectively communicating with the first chamber and the second chamber; and a water cooling head having a first liquid inlet and a second liquid inlet, the first liquid inlet and the second liquid inlet being respectively connected and communicating with the first interface and the second interface.

[0007] Compared to prior art, this application has the following advantages: Since the flow guiding structure is embedded in the window and connected between each first fluid pipe and each second fluid pipe, the first and second interfaces used to connect to the water cooling head can be located on the front, back, or long side of the water cooling radiator. Therefore, there are more options for configuring the pipelines, no longer limited to configuring them only on the first or second water tank, thus achieving the effect of diversified wiring.

[0018] The detailed description and technical content of this application are illustrated below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.

[0019] This application provides a liquid cooling heat dissipation device. Figures 1 to 4 show the first embodiment, and Figures 5, 6 and 7 show the second, third and fourth embodiments, respectively.

[0020] As shown in Figures 1 to 4, the first embodiment of the liquid cooling heat dissipation device of this application includes: a water cooling radiator 1, a water tank structure 2, a water cooling head 3, and a flow guiding structure 6. In one embodiment, it also includes a fan assembly 4.

[0021] The water radiator 1 is used for heat exchange using a liquid. The water radiator 1 mainly has a window W, into which a flow guiding structure 6 is embedded.

[0022] Specifically, the water-cooling radiator 1 has a front side 1a and a back side 1b spaced apart from each other, and a plurality of sides 1c surrounding the front side 1a and the back side 1b. This application does not limit the shape of the water-cooling radiator 1; in this embodiment, a cuboid is used as an example. Therefore, the plurality of sides 1c includes two long sides 1c1 spaced apart from each other and two short sides (not shown) spaced apart from each other. The aforementioned window W is located between the two short sides and extends through the front side 1a and the back side 1b of the water-cooling radiator 1. Alternatively, it may not extend through the front side 1a and the back side 1b but simply be a recess (not shown in the figure) from either the front side 1a or the back side 1b.

[0023] The water-cooled radiator 1 includes a fluid tube assembly 11 and a fin assembly 12. The fluid tube assembly 11 includes a plurality of fluid tubes spaced apart from each other, the plurality of fluid tubes including a plurality of first fluid tubes 111 and a plurality of second fluid tubes 112, and in one embodiment, a plurality of third fluid tubes 113. The fin assembly 12 includes a plurality of heat dissipation fins 121 (as shown in FIG3), each heat dissipation fin 121 being disposed between any two adjacent fluid tubes.

[0024] The water tank structure 2 is used to contain the liquid for heat exchange. The water tank structure 2 includes a first water tank 21 and a second water tank 22, and each third fluid pipe 113 is connected between the first water tank 21 and the second water tank 22, so that the first water tank 21 and the second water tank 22 are respectively located on the aforementioned two short sides of the water cooling radiator 1.

[0025] The flow guiding structure 6 is used to guide two water channels (one inlet and one outlet) within the aforementioned window W of the water cooling radiator 1. The flow guiding structure 6 is embedded in the window W and is connected and communicated between one end of each first fluid pipe 111 and one end of each second fluid pipe 112. The other end of each first fluid pipe 111 is connected and communicated with the first water tank 21, and the other end of each second fluid pipe 112 is connected and communicated with the second water tank 22.

[0026] The flow guiding structure 6 has a first chamber 6a and a second chamber 6b separated from each other. One end of each first fluid pipe 111 is connected to the first chamber 6a, and one end of each second fluid pipe 112 is connected to the second chamber 6b. The flow guiding structure 6 also has a first interface 613 connected to the first chamber 6a and a second interface 614 connected to the second chamber 6b.

[0027] The water-cooling head 3 is used to absorb heat from an electronic heating element (not shown in the figure); the water pump (not shown in the figure) for pumping liquid can be external or installed on a certain element. In this embodiment, the water-cooling head 3 is equipped with a water pump (not shown in the figure) to have the function of pumping liquid. The water-cooling head 3 has a first liquid inlet 31 and a second liquid inlet 32. The first liquid inlet 31 is connected to and communicates with the first interface 613, and the second liquid inlet 32 ​​is connected to and communicates with the second interface 614. Specifically, the liquid cooling heat dissipation device of this application also includes a first water pipe P1 and a second water pipe P2. The first water pipe P1 is bridged between the first liquid inlet 31 and the first interface 613, and the second water pipe P2 is bridged between the second liquid inlet 32 ​​and the second interface 614.

[0028] As shown in Figures 1, 3, and 4, the liquid pumped from the water-cooling head 3 is transported to the first chamber 6a of the flow guiding structure 6 via the first water pipe P1 and the first interface 613. In the first chamber 6a, the liquid is transported to the first water tank 21 via each of the first fluid pipes 111, and then flows back to the second water tank 22 via each of the third fluid pipes 113. The water-cooling head 3 also draws liquid from the second chamber 6b via the second water pipe P2 and the second interface 614, and draws liquid from the second water tank 22 via each of the second fluid pipes 112. The drawn liquid is then pumped to the first chamber 6a by the water pump installed in the water-cooling head 3.

[0029] Therefore, since the flow guiding structure 6 is embedded in the through-hole window W and connected between each of the first fluid pipes 111 and each of the second fluid pipes 112, the first interface 613 and the second interface 614 used to connect to the water cooling head 3 can be selectively located on the front 1a and back 1b of the water cooling radiator 1, as shown in Figures 1 and 7, respectively. Furthermore, the embedded position of the flow guiding structure 6 can also be adjacent to one of the two long sides 1c1 (that is, the opening position of the window W is adjacent to one of the two long sides 1c1), so that the first interface 613 and the second interface 614 can also be correspondingly opened on one of the long sides 1c1, as shown in Figures 5 or 6. Therefore, the liquid cooling heat dissipation device of this application can have a variety of choices when configuring pipelines (first water pipe P1, second water pipe P2), including: front 1a, back 1b or long side 1c1, no longer limited to being configured only on the first water tank 21 or the second water tank 22, thereby making the application have the effect of diversified wiring. It should be noted that one of the long sides 1c1 is parallel to each of the aforementioned fluid pipes (e.g., the first fluid pipe 111, the second fluid pipe 112, or the third fluid pipe 113).

[0030] Specifically, as shown in Figures 2 to 4, the flow guiding structure 6 includes a housing 61. The housing 61 has the aforementioned first interface 613 and second interface 614, and the housing 61 also contains a first chamber 6a and a second chamber 6b that are separated from each other in any feasible manner. In this embodiment, the separation of the chambers is illustrated by the example that the flow guiding structure 6 also includes a partition 62. The partition 62 is disposed inside the housing 61, so that the partition 62 separates the interior of the housing 61 into the first chamber 6a and the second chamber 6b.

[0031] Furthermore, the outer casing 61 may be pre-formed with a plurality of first insertion holes 611 and a plurality of second insertion holes 612. Each first insertion hole 611 connects to a first chamber 6a, and each second insertion hole 612 connects to a second chamber 6b. One end of each first fluid pipe 111 is inserted into each first insertion hole 611, and one end of each second fluid pipe 112 is inserted into each second insertion hole 612. To further prevent seepage and leakage, welding may be performed after insertion.

[0032] To enhance heat dissipation, as shown in Figure 1, the liquid cooling device of this application may further include a fan assembly 4. The fan assembly 4 is disposed on the front 1a or the back 1b of the water cooling radiator 1 (as shown in the figure, it is disposed on the front 1a). In order to avoid the location of the aforementioned first interface 613 and second interface 614, the fan assembly 4 may also have a notch (not shown). In addition, the fan assembly 4 may be a single-piece structure (not shown in the figure) or a multi-piece structure as shown in Figure 1, which includes a plurality of cooling fans 41 arranged side by side.

[0033] The liquid cooling heat dissipation device of this application may also include a first water pipe P1 and a second water pipe P2 as shown in the figures. In order to facilitate the connection of the water pipes to the flow guiding structure 6, two connectors may be connected to the aforementioned first interface 613 and second interface 614 respectively, as detailed below.

[0034] As shown in Figures 1 to 4, in the first embodiment of this application, since the first interface 613 and the second interface 614 are both located on the front 1a of the water cooling radiator 1, the two connectors are selected to be a first connector P11 and a second connector P21, both of which are in the shape of a straight line. Only a small section of the first connector P11 and the second connector P21 is inserted and fixed in the first interface 613 and the second interface 614 respectively, and connects the first chamber 6a and the second chamber 6b respectively. The remaining exposed sections of the first connector P11 and the second connector P21 protrude from the outer shell 61 as shown in Figure 2, so as to facilitate the bridging of the first water pipe P1 between the first infusion port 31 and the first connector P11, and the second water pipe P2 between the second infusion port 32 and the second connector P21.

[0035] As shown in Figure 5, in the second embodiment of this application, since the first interface 613 and the second interface 614 are both located on one of the long sides 1c1 of the water cooling radiator 1, the two connectors are selected to be an L-shaped first connector P12 and a second connector P22. The L-shaped connector includes a longitudinal segment and a transverse segment connected to each other in an L-shape. The longitudinal segments of the first connector P12 and the second connector P22 are respectively inserted and fixed in the first interface 613 and the second interface 614 and respectively connect to the first chamber 6a and the second chamber 6b. The transverse segments of the first connector P12 and the second connector P22 are respectively fitted to one end of the first water pipe P1 and the second water pipe P2. The other ends of the first water pipe P1 and the second water pipe P2 are respectively connected to and connected to the aforementioned first infusion port 31 and the second infusion port 32, as shown in Figure 1. Furthermore, the routing of the first water pipe P1 and the second water pipe P2 can also be arranged side-by-side with one of the long sidewalls 1c1, so that when the first connector P12, the second connector P22, or even parts of the first water pipe P1 and the second water pipe P2 are covered by the side cover 5, the first water pipe P1 and the second water pipe P2 can still extend in a roughly straight line. It should be noted that the side cover 5 is fixed to one of the long sidewalls 1c1 corresponding to the first connector P12 and the second connector P22.

[0036] As shown in Figure 6, the third embodiment of this application differs from the second embodiment only in that the cable arrangement of the first water pipe P1 and the second water pipe P2 is not parallel to one of the long side 1c1, so the side cover 5 cannot be used in the third embodiment; in addition, the first connector P13 and the second connector P23 of the third embodiment are the same as the first connector P12 and the second connector P22 of the second embodiment.

[0037] As shown in Figure 7, in the fourth embodiment of this application, the first interface 613 and the second interface 614 are both located on the back side 1b of the water cooling radiator 1. The two connectors are selected to be an L-shaped first connector P13 and a second connector P23. The first connector P13 and the second connector P23 in the fourth embodiment are also the same as the first connector P12 and the second connector P22 in the second embodiment.

[0038] As shown in Figure 8, in the fifth embodiment of this application, the difference between this embodiment and the previous embodiment is that it has a water pipe assembly P, and the aforementioned first water pipe P1 and second water pipe P2 are integrated in the water pipe assembly P. At least one wire groove P31 is formed in the water pipe assembly P for threading wires (not shown) that connect the water cooling radiator 1 and the water cooling head 3. The aforementioned wires can be used for power supply or signal transmission between the water cooling radiator 1 and the water cooling head 3.

[0039] As shown in Figure 9, specifically, the water pipe assembly P in this embodiment may further include a sleeve P3, with the first water pipe P1 and the second water pipe P2 passing through the sleeve P3, and a groove P31 is formed between the inner wall of the sleeve P3, the outer wall of the first water pipe P1 and the outer wall of the second water pipe P2. This application does not limit the number of grooves P31.

[0040] The water pipe assembly P referred to in this application is not limited to the aforementioned state. In another state of this embodiment as shown in FIG10, the water pipe assembly P' can also be an integrally formed pipe body in which a first water pipe P1, a second water pipe P2 and a trough P31 are formed.

[0041] It should also be noted that the aforementioned second, third, fourth, and fifth embodiments of the liquid cooling heat dissipation device of this application all have all the effects of the aforementioned first embodiment.

[0042] In conclusion, the liquid cooling heat dissipation device of this application can indeed achieve the intended use purpose and solve the shortcomings of the prior art; therefore, this patent application is filed.

[0043] The above description is merely a preferred embodiment of this application and does not limit the scope of this application.
