2. Description of Related Art
US Patent Application Publication No. 20120305221A1 discloses a heat pipe-attached heat sink, which comprises a radiation fin module (denoted by the numeral 10 in the patent drawing), a plurality of heat pipes (denoted by the numeral 20 in the patent drawing), and a bottom block (denoted by the numeral 30 in the patent drawing). The radiation fin module is composed of a plurality of first radiation fins (denoted by the numeral 1 in the patent drawing) and a plurality of second radiation fins (denoted by the numeral 1a in the patent drawing). The radiation fin module has two protruding blocks (denoted by the numeral 101 in the patent drawing) and a plurality of locating grooves (denoted by the numeral 112 in the patent drawing). The bottom block has an opening (denoted by the numeral 31 in the patent drawing) and a plurality of locating grooves (denoted by the numeral 32 in the patent drawing) provided at two sides of the opening. To assemble the heat sink, the protruding blocks of the radiation fin module are located at the opening of the bottom block, and firmly affixed to the bottom block. Each said locating groove of the radiation fin module is aligned with each said locating groove of the bottom block. Then each said heat pipe is disposed on the radiation fin module and the bottom block, and received in the corresponding locating groove. In use, the heat pipes are in direct contact with a heat source, so the heat pipes can dissipate heat.
The prior-art device uses the heat pipes to dissipate heat from the heat source. However, since the heat pipes are arranged into a single layer, the resultant heat dissipation is poor. Hence, the known heat pipe-attached heat sink needs to be improved.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a heat-dissipating structure that features for two layers of heat pipes that are separated and overlap each other and is capable of dissipating heat from a to-be-cooled article quickly.
Therefore, the heat-dissipating structure of the present invention comprises: a heat-dissipating partition, a first heat-dissipating layer, and a second heat-dissipating layer. The heat-dissipating partition has two opposite surfaces, wherein one said surface is defined as a first surface, and the other surface is defined as a second surface. The first heat-dissipating layer is composed of a plurality of first heat pipes. Each said first heat pipe is disposed on the first surface of the heat-dissipating partition. The second heat-dissipating layer is composed of a plurality of second heat pipes. Each said second heat pipe is disposed on the second surface of the heat-dissipating partition. Each said first heat pipe of the first heat-dissipating layer has at least one part overlapping at least one part of each said second heat pipe of the second heat-dissipating layer.
Thereby, with the overlaps between the first heat pipes and the second heat pipes, the heat from a to-be-cooled article can be transmitted successively to the first heat-dissipating layer, the heat-dissipating partition, and then the second heat-dissipating layer, thereby achieving fast heat dissipation.
The invention as well as a preferred mode of use, further objectives and advantages thereof will be best understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings.
