Therefore, a heat dissipating module structure is essential to the enhancement of the efficiency of the electronic products.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides a heat dissipating module structure for a heat generating device.

Referring to FIG. 1A through FIG. 1E, the heat dissipating module structure 1 according to the first preferred embodiment of the invention is revealed in the figures.

FIG. 1A is an outside perspective view of the heat dissipating module structure 1. As shown in FIG. 1A, the heat dissipating module structure 1 includes a heat-conducting device 10, a carrier 12, and a heat-conducting material 14. The heat-conducting device 10 has a first end 102 and a second end 104.

FIG. 1B is an outside perspective view of the carrier 12 in FIG. 1A. As shown in FIG. 1B, the carrier 12 has an upper surface 122, a bottom surface 124, and a hollow bore 126.

In one embodiment, the carrier 12 is formed of a metal material, a ceramic material, or a polymer material.

FIG. 1C is a cross section view of the carrier 12 of the heat dissipating module structure 1. As shown in FIG. 1C, the hollow bore 126 of the carrier 12 is adapted to receive the first end 102 of the heat-conducting device 10. The heat-conducting device 10 is inserted via the first end 102 thereof into the bore 126 such that the top 106 of the first end 102 of the heat-conducting device 10 is disposed near or aligned with the upper surface 122 of the carrier 12.

The heat-conducting material 14 surrounds the upper surface 122 of the carrier 12 such that the heat-conducting material 14 together with the upper surface 122 of the carrier 12 provide a supporting plane.

In one embodiment, the top 106 of the first end 102 of the heat-conducting device 10 is aligned with the upper surface 122 of the carrier 12 as shown in FIG. C. The heat-conducting material 14 fills up a residual space formed by the gap between the bore 126 and the first end 102 of the heat-conducting device 10. Practically, the carrier 12 and the heat-conducting material 14 need to be smoothed further, such that the heat-conducting material 14 together with the upper surface 122 of the carrier 12 provides a supporting plane.

In another embodiment, a distance exists between the upper surface 122 of the carrier 12 and the top 106 of the first end 102 of the heat-conducting device 10 as shown in FIG. D. The heat-conducting material 14 fills up a residual space, formed due to the distance, in the bore 126 near the upper surface 122 of the carrier 12. In practice, the carrier 12 and the heat-conducting material 14 need to be smoothed further, such that the heat-conducting material 14 together with the upper surface 122 of the carrier 12 provides a supporting plane.

In another embodiment, referring to FIG. 1E, the top 106 of the first end 102 of the heat-conducting device 10 is disposed outside the bore 126 (as shown in the partial cross section view of the heat dissipating module structure 1 on the left side of FIG. 1E), and then it is grinded, so that the top 106 of the first end 102 of the heat-conducting device 10 is aligned with the upper surface 122 of the carrier 12 (as shown in the partial cross section view of the heat dissipating module structure 1 on the right side of FIG. 1E). The heat-conducting material 14 fills up a residual space formed by the gap between the bore 126 and the first end 102 of the heat-conducting device 10. In practice, the carrier 12 and the heat-conducting material 14 need to be smoothed further, such that the heat-conducting material 14 together with the upper surface 122 of the carrier 12 provide a supporting plane.

It should be noted that the corresponding heat generating device (not shown in the figure) is to be mounted on the plane. Moreover, the heat generated by the heat generating device during operation thereof is conducted from the first end 102 of the heat-conducting device 10 to the second end 104 of the heating-conducting device 10.

In one embodiment, the heat-conducting material 14 is a heat-conducting paste such as a solder paste, a silver paste, a copper paste, or a paste material containing metal particles or ceramic particles. Practically, the heat-conducting paste fills up the residual space in the bore and then is cured.

In one embodiment, the heat-conducting device 10 is a heat pipe or a cylinder device formed of a material with high heat conductivity.

Referring to FIG. 2, a cross section view of the heat pipe is revealed and illustrated as the heat-conducting device 10. The heat-conducting pipe 10 includes a sealed metal pipe 101 and a porous capillary diversion layer 103. The metal pipe 101 has a vacuumed capacity 105 where there is a working fluid (not shown in the figure). The porous capillary diversion layer 103 is formed inside the capacity 105 and covers the inner wall of the metal pipe 101. What needs to be explained is that one end of the sealed metal pipe 101, which is originally unsealed, is sealed by heli-arc welding. Therefore, as shown in the cross section view of the heat pipe 10 in FIG. 2, the top 106 of the first end 102 of the heat pipe 10 is cohered to form a sphere after being heated.

In one embodiment, the heat dissipating module structure 1 further includes at least one heat-dissipating fin. The at least one heat-dissipating fin is mounted on a periphery of the heat-conducting device 10. In another embodiment, the heat dissipating module structure 1 further includes a heat sink. The heat sink is mounted on the second end 104 of the heat-conducting device 10.

The heat dissipating module structure, according to the second preferred embodiment of the invention, includes a heat-conducting device, a carrier formed of a material with high heat conductivity, and a heat-conducting paste.

The heat-conducting device, having a first end and a second end, is a heat pipe or a cylinder device formed of a material with high heat conductivity. The first end 11 forms a spherical surface inside and outside by sintering. Moreover, the heat-conducting device includes a sealed metal pipe and a porous capillary diversion layer.

Referring to FIG. 1A, the shape of the heat-conducting device 10 of the heat dissipating module structure 1 according to the invention could be a straighten pipe for practical application. Referring to FIG. 3, for particular application, the shape of the heat-conducting device 10 of the heat dissipating module structure 1 according to the invention could be bended appropriately upon practical demand.

The groove 226 of the carrier 22 is formed on the bottom surface 224 and adapted to receive the first end 202 of the heat-conducting device 20.

Referring to FIG. 4A, the first end 202 of the heat-conducting device 20 is disposed into the groove 226. The heat-conducting material 24 fills up a residual space between the first end 202 of the heat-conducting device 20 and the groove 226.

It should be noted that the corresponding heat generating device (not shown in the figure) is to be mounted on the upper surface 222 of the carrier 22. Moreover, the heat generated by the heat generating device during operation thereof is conducted from the carrier 22 through the heat-conducting material 24 and the first end 202 of the heat-conducting device 20 to the second end 204 of the heating-conducting device 20. Practically, the outer diameter of the first end 202 of the heat-conducting device 20 is substantially equal to the depth of the groove 226 and is also allowed to be less or larger than the depth of the groove 226.

The material, manufacturing process, and the shape of each device in the heat dissipating module 2 according to the second preferred embodiment of the invention are the same with those of each device in the heat dissipating 1 according to the first preferred embodiment of the invention.
