[0030] In this embodiment, the connection unit 2 is described as a plurality of connection units 2. Each connection unit 2 has at least one assembly 20 and at least one docking member 21. In this embodiment, the assembly 20 and the docking member 21 are plural, and one assembly 20 is paired with one docking member 21 to form a set of connection units 2, and the number of the assembly 20 and the docking member 21 can be adjusted according to the number of them combined on the water inlet 32 and the water outlet 33 of the water cooling unit 3. The assembly 20 has a fixed seat portion 200, and the fixed seat portion 200 is provided with an extension portion 205 and a plurality of first flanges 201. The extension portion 205 extends outward from the front side of the fixed seat portion 200, and the extension portion 205 has a first channel 207 with two open ends. One front opening 2081 is located at the front end of the extension portion 205, and the other rear opening 2082 is located at the rear end of the extension portion 205 and penetrates through the rear side of the fixed seat portion 200, so that the first channel 207 is located between the front and rear openings 2081 and 2082 of the extension portion 205 and is communicated with each other.

[0031] At least one leak-proof portion 206 is provided on the outer side of the extension portion 205. The leak-proof portion 206 is made of leak-proof materials (such as silica gel, rubber or other polymers (such as Teflon) materials). In this embodiment, a plurality of leak-proof portions 206 are annularly protruded on the outer side of the extension portion 205. The leak-proof portion 206 has the functions of preventing liquid leakage and tightly fitting and mating. The plurality of first flanges 201 respectively protrude outward from two opposite outer sides of the fixed seat portion 200. The plurality of first flanges 201 have a first through hole 202, and the first through hole 202 penetrates from the front side to the rear side of the first flange 201.

[0032] Continue to refer to Figure 1 、 Figure 2, the docking member 21 has a docking seat portion 211. The docking seat portion 211 is provided with a socket portion 215 and a plurality of second flanges 210. The socket portion 215 extends outward from the rear side of the docking seat portion 211, and a second channel 216 with two open ends is provided therein. One front opening 2171 is located at the front end of the socket portion 215 and penetrates through the front side of the docking seat portion 211, and the other rear opening 2172 is located at the rear end of the socket portion 215. The second channel 216 is located between the front and rear openings 2171, 2172 of the socket portion 215 and is connected to each other. And the second channel 216 is formed as a tapered channel with an inner diameter gradually increasing from the front opening 2171 of the socket portion 215 adjacent to the docking seat portion 211 towards the rear opening 2172. The front opening 2171 of the second channel 216 is connected and communicated with the rear opening 2082 opposite to the first channel 207. And the front side of the docking seat portion 211 is connected to the rear side of the fixed seat portion 200 of the assembly 20 to form the connection unit 2, and the connection manner between the docking seat portion 211 and the fixed seat portion 200 can be screw locking or fitting. With such a setting, the assembly 20 and the docking member 21 can be repeatedly assembled and disassembled to achieve the effect of repeated use.

[0033] The plurality of second flanges 210 of the docking seat portion 211 have a second perforation 212. The second perforation 212 penetrates from the front side of the second flange 210 to the rear side of the second flange 210. A plurality of fixing members 5 (such as screw members, rivets, pins, etc.) penetrate through the second perforation 212 of the plurality of second flanges 210 of the docking seat portion 211 and are combined together in the first perforation 202 of the plurality of first flanges 201 of the fixed seat portion 200.

The pipe connection end 41 of each pipe body 4 is inserted into the rear opening 2172 of the socket portion 215 of each connection unit 2, and is combined through the tapered second channel 216, the rear opening 2082 of the assembly 20 and the first channel 207 to the position of the front opening 2081 adjacent to the assembly 20. And because the diameter of the front opening 2171 of the tapered second channel 216 is smaller than the outer diameter of the pipe body 4, the pipe body 4 can be tightly and firmly fitted on the socket portion 215 of the docking member 21 without falling off, and it also has the function of effectively preventing the working liquid from leaking. In addition, a colloid (such as an adhesive or glue) is further provided between the contact of the pipe body 4 and the socket portion 215 of the docking member 21. The colloid is coated on the outside of the pipe connection end 41 of the pipe body 4 and adhered to the inner side of the socket portion 215 of the docking member 21 to enhance the bonding strength between the pipe body 4 and the socket portion 215 and improve the leak prevention effect.

[0034] The materials of the aforementioned assembly 20, docking member 21 and fixing member 5 are selected from metals, non-metals, plastics or other polymer materials.

[0035] The water cooling unit 3 has at least one pump 31, a water inlet 32 and a water outlet 33. In this embodiment, two pumps 31 are stacked in series. Each pump 31 has a chamber 301 filled with liquid. The chamber 301 communicates with the water inlet 32 and the water outlet 33. The water inlet 32 and the water outlet 33 are respectively opened on one side of the water cooling unit 3, and the water inlet 32 and the water outlet 33 are respectively butted against the assemblies 20 of the two connecting units 2. Specifically, the leak-proof parts 206 on the extension parts 205 of the plurality of connecting units 2 are respectively inserted into the water inlet 32 and the water outlet 33 of the water cooling unit 3 and tightly fitted and combined. The working liquid in the plurality of pipe bodies 4 can flow into the chambers 301 of the plurality of pumps 31 of the water cooling unit 3 through the water inlet 32 of the water cooling unit 3, and is driven by a driver (not shown in the figure) of the plurality of pumps 31 to flow out the working liquid in their respective chambers 301 towards the water outlet 33. Finally, the pipe body 4 connecting the water outlet 33 conveys the working liquid to another water cooling unit (such as a water cooling radiator; not shown in the figure) for continuous circulating heat dissipation. In addition, a plurality of locking holes 34 can be provided around the water inlet 32 and the water outlet 33 of the water cooling unit 3. The plurality of connecting units 2 are screwed and fixed on the plurality of locking holes 34 opposite to the water cooling unit 3 by the plurality of fixing parts 5 (taking screw parts as an example in this case), which is beneficial to increasing the bonding strength between the connecting unit 2 and the water cooling unit 3.

[0036] In the above embodiment, the water cooling unit 3 is described as a plurality of pumps 31, but it is not limited thereto. In other alternative embodiments, the water cooling unit 3 can be a single pump or a water cooling head or other water cooling units (such as a water cooling radiator).

[0037] Therefore, through the structural design of the present invention, after the pipe body 4 correspondingly penetrates through the second channel 216 of the docking member 21 and then is inserted into the first channel 207 of the extension part 205 of the assembly 20 to make the docking member 21 and the assembly 20 be disposed in a butt joint, and the fixing seat part 200 of the assembly 20 is correspondingly inserted into the water cooling unit 3, the pipe body 4 can be firmly installed on the water cooling unit 3 through the connecting unit 2, so that the defect that the conventional pipe body is fixed on the water cooling unit by welding and is prone to working liquid leakage problems can be improved.

[0038] In addition, the manufacturing processes of the assembly 20 and the docking member 21 are simple, and they can be repeatedly assembled and disassembled to achieve the effect of repeated use, thereby greatly reducing the production cost.

[0039] As described above, the present invention has the following advantages compared with the prior art:

[0040] 1. Greatly reduce the problem of working liquid leakage.

[0041] 2. The manufacturing process is simple.

[0042] 3. It can be reused, significantly reducing production costs.

[0043] The above has given a detailed description of the present utility model. However, what is described above is only a preferred embodiment of the present utility model, and it should not be used to limit the scope of implementation of the present utility model.
