[0040] The detailed description and technical contents of the present application are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and explanation and are not intended to limit the present application.

[0041] The present application provides a liquid cooling device, such as Figures 1 to 4 The first embodiment is shown. Figure 5 , Figure 6 and Figure 7 The figures show the second, third and fourth embodiments respectively.

[0042] like Figures 1 to 4 As shown, the first embodiment of the liquid cooling device of the present application includes: a water cooling radiator 1, a water tank structure 2, a water cooling head 3 and a flow guide structure 6, and in one embodiment, it also includes a fan assembly 4.

[0043] The water-cooling radiator 1 is used for heat exchange by using a liquid. The water-cooling radiator 1 is mainly provided with a window W, in which the flow-guiding structure 6 is embedded.

[0044] Specifically, the water-cooling radiator 1 has a front face 1a and a back face 1b that are spaced apart and opposite to each other, and a plurality of side edges 1c that surround the front face 1a and the back face 1b. The present application does not limit the shape of the water-cooling radiator 1. In this embodiment, a rectangular parallelepiped is used as an example for explanation, so the plurality of side edges 1c include two long side edges 1c1 that are spaced apart and opposite to each other, and two short side edges that are spaced apart and opposite to each other (element symbols are not indicated). The aforementioned window W is located between the two short side edges and passes through the front face 1a and the back face 1b of the water-cooling radiator 1. Of course, it may not pass through but only be a groove that is sunken from the front face 1a or the back face 1b (not shown in the figure).

[0045] The water cooling radiator 1 comprises a fluid pipe assembly 11 and a fin assembly 12. The fluid pipe assembly 11 comprises a plurality of fluid pipes spaced apart and arranged side by side, the plurality of fluid pipes comprising a plurality of first fluid pipes 111 and a plurality of second fluid pipes 112, and in one embodiment further comprising a plurality of third fluid pipes 113. The fin assembly 12 comprises a plurality of heat dissipation fins 121 (such as Figure 3 As shown), each heat dissipation fin 121 is disposed between any two adjacent fluid tubes.

[0046] The water tank structure 2 is used to contain liquid for heat exchange. The water tank structure 2 includes a first water tank 21 and a second water tank 22. Each third fluid pipe 113 is bridged and 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.

[0047] The flow guiding structure 6 is used to guide two water paths (without component symbols) in 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.

[0048] 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 tube 111 is connected to the first chamber 6a, and one end of each second fluid tube 112 is connected to the second chamber 6b; the flow-guiding structure 6 is also provided with a first interface 613 connected to the first chamber 6a and a second interface 614 connected to the second chamber 6b.

[0049] 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 set in a certain element. In this embodiment, a water pump (not shown in the figure) is set in the water cooling head 3 to have the function of pumping liquid. The water cooling head 3 has a first infusion port 31 and a second infusion port 32. The first infusion port 31 is connected and communicated with the first interface 613, and the second infusion port 32 is connected and communicated with the second interface 614. Specifically, the liquid cooling heat dissipation device of the present application also includes a first water pipe P1 and a second water pipe P2. The first water pipe P1 is bridged between the first infusion port 31 and the first interface 613, and the second water pipe P2 is bridged between the second infusion port 32 and the second interface 614.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, the liquid pumped from the water-cooling head 3 is transported to the first chamber 6a of the guide structure 6 via the first water pipe P1 and the first interface 613, and the liquid in the first chamber 6a is transported to the first water tank 21 via each first fluid pipe 111, and then flows back to the second water tank 22 via each third fluid pipe 113; the water-cooling head 3 also extracts the liquid in the second chamber 6b via the second water pipe P2 and the second interface 614, and utilizes each second fluid pipe 112 to extract the liquid in the second water tank 22, and then pumps the extracted liquid into the first chamber 6a via the water pump provided on the water-cooling head 3.

[0051] Thus, since the flow guide structure 6 is embedded in the through window W and connected between each first fluid pipe 111 and each second fluid pipe 112, the first interface 613 and the second interface 614 used to connect to the water cooling head 3 can be connected as shown in FIG. Figure 1 and Figure 7As shown, the guide structure 6 is selectively located at the front side 1a and the back side 1b of the water cooling radiator 1; furthermore, the embedding position of the guide structure 6 can also be adjacent to one of the two long sides 1c1 as shown in the figure (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 Figure 5 or Figure 6 As shown, the corresponding opening is located on one of the long sides 1c1. Therefore, when configuring the pipelines (first water pipe P1, second water pipe P2) of the liquid cooling device of the present application, there are various options, including: the front 1a, the back 1b or the long side 1c1, and it is no longer limited to being configured on the first water tank 21 or the second water tank 22, so that the present application has the effect of diversified wiring. It should be noted that one of the long sides 1c1 and the aforementioned fluid pipes (for example: the first fluid pipe 111, the second fluid pipe 112 or the third fluid pipe 113) are arranged side by side with each other.

[0052] Specifically, if Figures 2 to 4 As shown, the flow guiding structure 6 includes a shell 61, the shell 61 is provided with the aforementioned first interface 613 and second interface 614, and the shell 61 is further provided with a first chamber 6a and a second chamber 6b separated from each other in any feasible manner. The chamber separation method in this embodiment is described by taking the example that the flow guiding structure 6 further includes a partition 62, and the partition 62 is arranged in the shell 61, so that the partition 62 separates the inside of the shell 61 into the first chamber 6a and the second chamber 6b.

[0053] In addition, the housing 61 may be pre-opened with a plurality of first plug holes 611 and a plurality of second plug holes 612, each first plug hole 611 is connected to the first chamber 6a, each second plug hole 612 is connected to the second chamber 6b, and one end of each first fluid pipe 111 is plugged into each first plug hole 611, and one end of each second fluid pipe 112 is plugged into each second plug hole 612. In order to strengthen the prevention of seepage and leakage, welding may be performed after plugging.

[0054] In order to enhance heat dissipation, Figure 1 As shown, the liquid cooling device of the present application may also include a fan assembly 4, which is disposed on the front side 1a or the back side 1b of the water cooling radiator 1 (as shown in the figure, it is disposed on the front side 1a), and in order to avoid the location of the first interface 613 and the second interface 614, the fan assembly 4 may also have a notch (not marked with a component symbol). In addition, the fan assembly 4 may be a single-piece structure (not shown in the figure), or it may be as follows Figure 1 The multi-piece structure shown includes a plurality of cooling fans 41 arranged side by side.

[0055] The liquid cooling device of the present application may also include a first water pipe P1 and a second water pipe P2 as shown in the figures, and in order to facilitate the connection of the water pipe to the guide structure 6, two joints may be respectively connected to the aforementioned first interface 613 and the second interface 614, as described in detail below.

[0056] like Figures 1 to 4 In the first embodiment of the present application shown in the figure, since the first interface 613 and the second interface 614 are both located on the front side 1a of the water cooling radiator 1, the two joints are selected to use a first joint P11 and a second joint P21 both in the shape of a straight line. Only a small section of the first joint P11 and the second joint P21 are respectively inserted and fixed in the first interface 613 and the second interface 614 to connect the first chamber 6a and the second chamber 6b respectively, and the remaining exposed sections of the first joint P11 and the second joint P21 are as shown in FIG. Figure 2 As shown, it protrudes from the housing 61 to facilitate bridging 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.

[0057] like Figure 5 In the second embodiment of the present application shown, 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 joints are selected to use a first joint P12 and a second joint P22, both of which are L-shaped. The so-called L-shaped joint includes a longitudinal section and a transverse section connected to each other in an L-shape. The longitudinal sections of the first joint P12 and the second joint P22 are respectively inserted and fixed in the first interface 613 and the second interface 614 to connect the first chamber 6a and the second chamber 6b respectively. The transverse sections of the first joint P12 and the second joint P22 are respectively provided for the first water pipe P1 and the second water pipe P2 to be sleeved at one end. The other ends of the first water pipe P1 and the second water pipe P2 are connected to the first water pipe P1 and the second water pipe P2. Figure 1 As shown, the first water pipe P1 and the second water pipe P2 are respectively connected and communicated with the aforementioned first infusion port 31 and the second infusion port 32. In addition, the wiring method of the first water pipe P1 and the second water pipe P2 can also be arranged side by side with one of the long sides 1c1, so that when a side cover 5 is used to cover the first joint P12, the second joint P22 or even a part of the first water pipe P1 and the second water pipe P2, the first water pipe P1 and the second water pipe P2 can still extend roughly in a straight line. It should be noted that the side cover 5 is fixed on one of the long sides 1c1 corresponding to the first joint P12 and the second joint P22.

[0058] like Figure 6The third embodiment of the present application shown in the figure differs from the second embodiment only in that the wiring method of the first water pipe P1 and the second water pipe P2 is not arranged side by side with one of the long sides 1c1, so the side cover 5 cannot be used in the third embodiment; in addition, the first joint P13 and the second joint P23 of the third embodiment are the same as the first joint P12 and the second joint P22 of the second embodiment.

[0059] like Figure 7 In the fourth embodiment of the present application shown, the first interface 613 and the second interface 614 are both located on the back side 1b of the water cooling radiator 1, and the two joints are selected to use a first joint P13 and a second joint P23 which are also L-shaped, and the first joint P13 and the second joint P23 of the fourth embodiment are also the same as the first joint P12 and the second joint P22 of the second embodiment.

[0060] like Figure 8 In the fifth embodiment of the present application shown, the difference between this embodiment and the aforementioned embodiments 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, and at least one wire groove P31 is formed in the water pipe assembly P for passing the wires (not shown) connected to the water cooling radiator 1 and the water cooling head 3, and the aforementioned wires can be used for power supply or signal transmission between the water cooling radiator 1 and the water cooling head 3.

[0061] like Fig. 9 As shown, specifically, the water pipe assembly P of this embodiment may further include a sleeve P3, the first water pipe P1 and the second water pipe P2 are inserted into the sleeve P3, and a wire 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. The present application does not limit the number of wire grooves P31.

[0062] The water pipe assembly P referred to in this application is not limited to the aforementioned state. Fig.10 In another aspect of the present embodiment, the water pipe assembly P' may also be an integrally formed pipe body in which the first water pipe P1, the second water pipe P2 and the wire groove P31 are formed.

[0063] It should also be noted that the aforementioned second, third, fourth and fifth embodiments of the liquid cooling device of the present application all have all the effects of the aforementioned first embodiment.

[0064] In summary, the liquid cooling device of the present application can achieve the expected purpose of use and solve the deficiencies of the prior art, and therefore a patent application is filed.

[0065] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Therefore, all equivalent structural changes made by using the description and drawings of the present application are also included in the scope of the present application. The present application may also have other embodiments. Without departing from the spirit and essence of the present application, technicians familiar with the field can make various corresponding changes and deformations according to the present application, but these corresponding changes and deformations should belong to the protection scope of the claims attached to the present application.
