The lower fin assembly 12 has a plurality of upwardly protruding lower grille portions 121 spaced apart along its width. The upper grille portions 111 and the lower grille portions 121 are engaged in a staggered manner. The upper grille portions 111 are at least able to move relative to the lower grille portions 121 within a range of engagement stroke (engagement depth along the vertical direction) in the vertical direction and maintain mutual thermal contact. In this document, the spring member 5, the mounting member 6, and the pin member 7 can be collectively referred to as fastening components.

[0061] Two mounting members 6 are provided, each respectively abutting the two sides of the interlocking upper grille portion 111 and lower grille portion 121 along the width direction. Two pins 7 are provided, one of which is vertically positioned between the front ends of the upper fin assembly 11 and the lower fin assembly 12, and both ends of the pin 7 along the width direction are respectively inserted and fixed to the mounting member 6, thereby confining the interlocking upper grille portion 111 and lower grille portion 121 along the width direction between the two mounting members 6. Figures 6 to 9 As shown, specifically, the ends of the pin 7 pass through the through holes (unlabeled) formed on the mounting member 6 and are bent to form hooks (unlabeled) that abut against the outer surface of the mounting member 6. Furthermore, since the other pin 7 assembled at the rear end of the fin module 1 has the same structure as the pin 7 assembled at the front end of the fin module 1, its structure and assembly relationship with the upper grille 111 and lower grille 121 will not be described in detail here.

[0062] Furthermore, in a preferred embodiment of this application, two spring members 5 are provided. One spring member 5 is assembled at the front end of the fin module 1 (that is, at the front end of the interlocking upper grille portion 111 and lower grille portion 121), and the other spring member 5 is assembled at the rear end of the fin module 1 (that is, at the rear end of the interlocking upper grille portion 111 and lower grille portion 121).

Furthermore, the spring member 5 assembled at the rear end of the fin module 1 has the same structure as the spring member 5 assembled at the front end of the fin module 1; its structure and assembly relationship with the upper grille portion 111 and the lower grille portion 121 will not be described in detail here. In this application, the cross-section of the meandering elastic portion 53 along the plane perpendicular to the width direction is S-shaped; however, it can also be designed as Z-shaped, W-shaped, V-shaped, or U-shaped, etc.

The ends of the first fixing strip 51 and the second fixing strip 52 located on the same side along the width direction are restricted within the same limiting hole 60 and can move within the limiting hole 60 in the vertical direction, thereby changing the engagement depth of the upper fin assembly 11 and the lower fin assembly 12 in the vertical direction, thereby realizing the overall height change of the fin module 1 in the vertical direction.

[0064] Please refer to the reference. Figures 2 to 9 As shown, the lower edge of the mounting member 6 protrudes outward along its width to form a fixing wing 10. During assembly, the fin module 1 is inserted from front to back into the mounting cavity 31 of the liquid cooler block 3. The retaining wing 32 is correspondingly engaged with the fixing wing 10 for fixation, and the liquid cooler block 3 and the fin module 1 are assembled into an integral component. By engaging the fixing wing 10 with the retaining wing 32, the fin module 1 and the liquid cooler block 3 are assembled and fixed. In a preferred embodiment of this application, the fixing wing 10 is formed by bending the mounting member 6, and the fixing wing 10 and the mounting member 6 are an integral part.

[0065] In a preferred embodiment, the upper fin assembly 11 is integrally fixed to the mounting member 6, and the lower fin assembly 12 is movable relative to the upper fin assembly 11 and the mounting member 6 in the vertical direction. In another embodiment, the two mounting members 6 only limit the interlocking upper grille portion 111 and lower grille portion 121 in the width direction, and each upper fin assembly 11 or lower fin assembly 12 is movable relative to the mounting member 6 in the vertical direction.

[0066] Please refer to the reference. Figures 2 to 9 As shown in this application, the fin module 1 further includes a spring plate portion 4, which is coupled to the outer surface of the mounting member 6. The spring plate portion 4 elastically contacts two opposing inner surfaces of the mounting cavity 31 along the width direction. In a preferred embodiment, the spring plate portion 4 and the mounting member 6 are located on the inner bottom surface 303 of the mounting cavity 31 along the vertical direction. Figure 5(As shown) and between the retaining wing 32. The spring piece 4 is used to increase the thermal contact between the fin module 1 and the liquid cooling block 3, thereby improving the heat pipe efficiency. In a preferred embodiment of this application, the spring piece 4 is formed by stamping and bending an independent metal sheet, including a plate-shaped main body (not labeled) and a cantilevered spring piece 4 integrally connected to the main body. The main body is correspondingly fitted and fixed to the outer surface of the mounting member 6. The cantilevered spring piece 4 is formed by protruding outward from the outer surface of the mounting member 6.

[0067] Please refer to the reference. Figures 3 to 8 As shown in this application, to ensure a more stable connection between the fin module 1 and the liquid cooling block 3, a locking portion 101 is formed on the fixed wing portion 10, extending downward and forward at an angle. A locking groove 321 is formed on the surface of the retaining wing portion 32 that contacts the fixed wing portion 10, and the locking portion 101 is correspondingly locked within the locking groove 321. Furthermore, the liquid cooling block 3 also includes a stop portion 33 formed by the rear end edge of the mounting cavity 31 protruding into the mounting cavity 31. After the fin module 1 is inserted and limited into the mounting cavity 31 of the liquid cooling block 3 from front to back, the rear end of the mounting member 6 is correspondingly stopped at the stop portion 33. Of course, in other embodiments, the stop portion 33 can also be designed to have a larger area to block the rearward opening of the mounting cavity 31 formed by the top member 301 and the two side members 302.

[0068] Please refer to Figure 2 and Figure 3 As shown in the figure, in this application, the liquid cooling block 3 is provided with a liquid cooling transmission channel 300 inside. The liquid cooling transmission channel 300 forms an inlet 3001 and an outlet 3002 exposed inside the liquid cooling block 3. The liquid cooling transmission channel 300 extends inside the liquid cooling block 3 to form a meandering liquid flow channel. In use, the coolant flows in through the inlet 3001, flows through the meandering liquid flow channel, and flows out through the outlet 3002, thereby achieving rapid heat removal. The liquid cooling transmission channel 300 can be an implanted metal tube, or it can be directly formed from the inside of the liquid cooling block 3 through processing. For example, the liquid cooling block 3 can be designed as an assembly of upper and lower pieces, with the surface of the upper and lower pieces recessed to form the liquid flow channel. In the figures of this application, the liquid cooling transmission channel 300 is embedded in the upper surface of the top member 301. Of course, it can also be buried inside the top member 301, or simultaneously buried inside the two side members 302.

[0069] It should be noted that in the embodiments shown in the accompanying drawings of this application, the two fin modules 1 are assembled with one liquid cooling block 3. In this embodiment, a spacer 304 is formed in the middle of the two side members 302 along the width direction. In one embodiment, the height of the spacer 304 in the vertical direction is lower than that of the side members 302, and the retaining wings 32 are respectively formed on the two side surfaces of the spacer 304 in the width direction. The spacer 304 is located above the two side-by-side enclosures 8 or flush with the upper surface of the two side-by-side enclosures 8. In another embodiment, the height of the spacer 304 in the vertical direction is basically the same as that of the side members 302, and the lower end of the spacer 304 is inserted between the two side-by-side enclosures 8. However, in either embodiment, the spacer 304 can also be understood as a side member 302.
