One holder, this holder system is arranged in the portion of being heated of above-mentioned heat pipe.

The purpose of this utility model can also reach by following measure:

Each radiator system has an arc-shaped base respectively, and the end face system of this arc-shaped base is provided with most junction surfaces, and the end face of this arc-shaped base system extension majority is radial fin.

Each radiator system has an arc plate body respectively, and the biend system of this arc plate body is extended with majority and is radial fin.

Each radiator system is screwed togather with fixation kit.

Each radiator system is to weld in addition combination.

The portion of being heated of each heat pipe is a direct rod shape, and its linkage section is the multiple bending arc shape of the combination of direction difference.

This holder has two base plates at least, and one of each base plate correspondence mask has majority that the recessed groove of heat pipe can be set.

Each base plate system cooperates most fixation kits or solid welding to carry out combination.

The utility model has following advantage compared to existing technology:

The weight of heat abstractor be can alleviate, and preferable radiating effect and the effect that reduces cost reached.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See also Fig. 1, shown in Figure 2, the Improvement type construction for heat radiating device that the utility model is related, it is made of a heat-sink unit 1, one an above heat pipe 2 and a holder 3, can alleviate the weight of heat abstractor, and reach preferable radiating effect and the effect that reduces cost.

The above-mentioned heat-sink unit of being carried 1 has second radiator 11 at least, each radiator 11 is to have an arc-shaped base 111 respectively, the end face system of this arc-shaped base 111 is provided with most junction surfaces 112, and the end face of this arc-shaped base 111 system extends majority and is radial fin 113, each fin 113 is the length that can be required to be different size according to the institute of actual state, make each radiator 11 form a curved end, and be respectively equipped with a groove 114 on each radiator 11 corresponding one side.

Each heat pipe 2 is to have the portion of being heated 21, a cooling end 22, an and linkage section 23 that connects the portion of being heated 21 and cooling end 22 respectively, and the cooling end 22 of each heat pipe 2 is to be a bending arc shape, and the portion of being heated 21 of each heat pipe 2 and linkage section 23 are size and the shape that can comply with the difference that is required to be of actual use, and this cooling end 22 is fixedly arranged in the groove 114 on the second radiator 11 corresponding one sides, and each radiator 11 is screwed togather or in the mode of welding each heat pipe 2 is combined with radiator 11 with fixation kit 115.
