[First Embodiment]

Referring to FIG. 1 , a first embodiment of the present invention provides a heat dissipation module Z, including: a heat generating structure H, a heat dissipation structure C, and a heat pipe structure P, and opposite end portions of the heat pipe structure P (P1) P2) can contact the heat generating structure H and the heat dissipating structure C, respectively. For example, the heating structure H can be A central processing unit (CPU) or any type of functional chip, and the heat dissipation structure C may be a heat sink composed of a plurality of heat dissipation fins, and a fan (not shown) may be attached adjacent to the position to enhance heat dissipation. Heat dissipation performance.

Referring to FIG. 2 and FIG. 3A to FIG. 3D , the method for manufacturing the heat pipe structure P may include the following steps. First, as shown in FIG. 2 and FIG. 3A , a hollow pipe member 1 ′ (S100) is provided, and then A pre-compression track 10' is formed on the outer surface 100' of the hollow tubular member 1' (S102). For example, the pre-compression track 10' may be formed on the topmost end of the outer surface 100' of the hollow tubular member 1'. In addition, the pre-compression track 10' can be formed by shallow rolling (ie, the pre-compressed track 10' can be formed on the outer surface 100' of the hollow tubular member 1' via a "destructive" process) as The subsequent rolling reference line for deep rolling. Of course, the pre-compression track 10' can also be formed on the outer surface 100' of the hollow tubular member 1' by an external means (for example, printing, coating, etc.), that is, the pre-compressed track 10' can be processed through "non-destructive" processing. The manner is formed on the outer surface 100' of the hollow tubular member 1'. However, the manner of forming the pre-compression track 10' disclosed in the present invention is not limited to the example of the first embodiment described above.

Next, as shown in Fig. 2 and Fig. 3B, a sintered member 2' is placed in the hollow tubular member 1', wherein the tip end 200' of the sintered member 2' corresponds to the pre-compression track 10' of the hollow tubular member 1' (S104). Further, the sintered member 2' is not formed in advance on the inner surface 101' of the hollow tubular member 1', but is a separate member which is previously produced by powder sintering. When the sintered member 2' is placed in the hollow tubular member 1', the top end 200' of the sintered member 2' needs to be located just below the pre-compression track 10' of the hollow tubular member 1' to facilitate subsequent positioning of the sintered member 2'. . For example, the winding member 2' may be a sintered metal powder formed by sintering a metal powder (such as copper powder) or a metal mesh. The sintered metal mesh (i.e., composite capillary structure) formed after the winding is performed (for example, a copper mesh), but the invention is not limited thereto.

Then, as shown in Figures 2 and 3C, the pressure is applied downward along the pre-compression track 10' such that the inner surface 101' of the hollow tubular member 1' projects inwardly against the top end 200' of the sintered member 2' ( S106). For example, the downward pressing method may be deep rolling, and the strength of the deep rolling may be stronger than the shallow rolling applied when the pre-compression track 10' is formed, thereby causing the inner surface of the hollow tubular member 1'. 101' will bulge inwardly against the top end 200' of the sintered member 2'. At this time, the top end 200' and the bottom end 201' of the sintered member 2' simultaneously abut against the inner surface 101' of the hollow tubular member 1' so that the sintered member 2' is positioned and stuck in the hollow tubular member 1'.

Finally, in conjunction with FIG. 2 and FIG. 3D (where FIG. 3D is a schematic cross-sectional view of any section in FIG. 1), the hollow tubular member 1' is flattened so that the hollow tubular member 1' and the sintered member 2' are respectively A flat hollow tubular body 1 and a sintered body 2 (S108) stuck in the flat hollow tubular body 1 are formed, wherein the wound body 2 may be a sintered metal powder or a sintered metal mesh. Further, before the step S108 of flattening the hollow tubular member 1', the present invention further comprises: filling the working fluid (not shown, for example, pure water, ammonia water, methanol, ethanol, acetone, heptane or the above). a mixed liquid solution of any two or more working liquids is placed in the hollow tubular member 1', followed by evacuating the hollow tubular member 1', and then closing the opposite ends of the hollow tubular member 1' (as shown in FIG. 1) ).

The channel 100 is cooled to be transferred to the heat dissipation structure C. When the gaseous working fluid is cooled at the heat dissipation structure C (ie, When it is converted into a liquid state, the working fluid which is in a liquid state is guided back to the heat generating structure H along the sintered body 2 having the capillary structure, whereby the endothermic-exothermic cycle is repeated.
