At present, heat pipe heat radiation technology is applied to the field of radiating of space flight, computer, electric elements, electronic equipment, achieves good effect.The appearance of heat pipe, makes the cooling system of power electronic equipment have new development.Heat pipe is the artificial component that a kind of conductivity of heat is fabulous, and conventional heat pipe is made up of three parts: main body is a metal tube closed, and there are a small amount of working media and capillary structure in inside, and air and other foreign material in pipe must foreclose.Make use of three kinds of physics principles: (1) under vacuum conditions, the boiling point of liquid reduces during heat pipe work；(2) much higher than sensible heat of the latent heat of vaporization of material of the same race；(3) suction force of liquid can be made liquid flow by porous capillary structure.
Heat-pipe radiator is the new product utilizing hot pipe technique many old-fashioned radiators or heat exchange product and system can be done great improvement and be produced.The thermal resistance of radiator is that the effective area in the heat conductivity by material and volume determines.Entity aluminum or copper radiator are when volume reaches 0.006m3, then strengthen its volume and area can not be obviously reduced thermal resistance.For the discrete-semiconductor device of two-side radiation, the thermal resistance of air-cooled full copper or full aluminium radiator can only achieve 0.04 DEG C/W, and heat-pipe radiator can reach 0.01 DEG C/W.Under free convection cooling condition, heat-pipe radiator can improve more than ten times than the performance of entity radiator.
But, inventor finds when realizing the present invention, no matter which kind of radiating mode, and its final heat dissipation vehicle is air, and other are all middle articulatings.Existing heat pipe heat radiation needs the effect that heat pipe finned could have been obtained, and existing fin area of dissipation is limited to, and adopts adhesive technology to be connected between heat pipe with fin, have impact on radiating effect.
Summary of the invention
The problem that the embodiment of the present invention to solve is to provide radiator, to overcome the bad defect of radiating effect in prior art.
For reaching above-mentioned purpose, the technical scheme of the embodiment of the present invention provides a kind of radiator, and described radiator includes array heat pipe and can increase the Special-shaped fin of stack effect, and described array heat pipe and Special-shaped fin are one-body molded, and centre does not have gap.
Further, described array heat pipe includes one or more independent heat pipe.
Further, when described array heat pipe includes many independent heat pipes, described many heat pipes are uniformly arranged.
Further, the cavity of described inside heat pipe is built with phase-change working substance.
Further, the cross section of described inside heat pipe cavity is circular or polygon.
Further, the two ends of described array heat pipe are formed by welded seal after evacuation.
Further, described Special-shaped fin is the one in work shape fin, S shape fin, C shape fin, dihedral fin or degree of lip-rounding fin.
Further, described Special-shaped fin is arranged on one side or the bilateral of described array heat pipe.
Further, the material of described array heat pipe is aluminium alloy.
Further, described Special-shaped fin and array heat pipe are extruded by aluminium alloy process equipment.
Compared with prior art, technical scheme has the advantage that
The radiator of the present invention contains Special-shaped fin, and Special-shaped fin is one-body molded with array heat pipe, thus adding area and the stack effect of fin, solving that heat pipe for thermal conductivity is fast but problem that radiating efficiency is low, adding radiating effect；Decrease operation simultaneously, saved cost, make array thermal tube radiator more safe, reliable, environmentally friendly；It addition, the present invention expands the applications such as Aeronautics and Astronautics, computer, electric elements, electronic equipment, domestic radiator, there is significantly high social value and economic benefit.
