Heat-conducting assembly for heat pipes of different diameters and heat sink having the same

Abstract

In a heat-conducting assembly for heat pipes of different diameters and a heat sink having such assembly, the heat-conducting assembly includes a heat-conducting base, a set of first heat pipes and a set of second heat pipes. A heat-conducting surface of the heat-conducting base is provided with a plurality of accommodating troughs. The diameter of the set of second heat pipes is smaller than that of the set of first heat pipes. The first heat pipe and the second heat pipe of different diameters are disposed in the accommodating troughs respectively. The heat pipes penetrate a plurality of fins to form the heat sink. With this arrangement, the ratio of heat pipes arranged on the heat-conducting surface can be increased and the heat-conducting efficiency thereof can be improved.

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a heat-conducting assembly, and in particular to a heat-conducting assembly having heat pipes.[0003]2. Description of Prior Art[0004]Since heat pipes have many advantages such as a large heat-conducting capacity, light weight, simple structure, low electricity consumption and low price, they have been widely used in the heat conduction of electronic elements. The heat pipes are capable of conducting the heat generated by electronic heat-generating elements rapidly, so that the heat accumulation in the electronic heat-generating elements can be solved.[0005]Please refer to FIG. 1, which shows the combination of heat pipes and a heat-conducting base in prior art. A heat-conducting surface 100a of a heat-conducting base 10a is provided with a plurality of through troughs 101a. A partition 102a is formed between the respective through troughs 101a, so that the heat pipes 20a can be arranged ...

[0010]The present invention provides a heat sink having a heat-conducting assembly for heat-pipes of different diameters, which includes a heat-conducting base, a set of first heat pipes, a set of second heat pipes and a plurality of fins. The heat-conducting base has a heat-conducting surface. The heat-conducting surface is provided with a plurality of accommodating troughs. The set of first heat pipes includes at least one first heat pipe. The first heat pipe has a heat-absorbing section and a condensing section. The heat-absorbing section of the first heat pipe is disposed in the accommodating trough. The set of second heat pipes includes at least one second heat pipe. The second heat pipe has a heat-absorbing section and a condensing section. The heat-absorbing section of the second heat pipe is disposed in the accommodating trough. The diameter of the set of second heat pipes is smaller than that of the set of first heat pipes. The condensing sections of the first heat pipe and the second heat pipe are penetrated by the plurality of parallel fins. The sizes of the accommodating troughs of the heat-conducting base correspond to the diameters of the first heat pipe and the second heat pipe respectively.

[0011]In comparison with prior art, according to the present invention, a plurality of heat pipes of different diameters are connected with the heat-conducting base. Further, the heat-absorbing section of the large-diameter first heat pipe and the heat-absorbing section of the small-diameter second heat pipe are arranged on the heat-conducting surface of the heat-conducting base at intervals. In this way, the ratio of the heat pipes arranged on the heat-conducting surface can be increased. That is, the number or density of the heat pipes arranged in the same heat-conducting surface can be increased, and thus the heat-conducting efficiency can be improved.

Problems solved by technology

However, in the heat-conducting surface 100a, two contacting areas 100b and 100b located outside the three heat pipes 20a are wasted because the contacting areas 100b and 100c are too small to accommodate a heat pipe.
