The specific embodiment:

In order to understand better and to implement, provide embodiment below in conjunction with accompanying drawing and further describe a kind of electromagnetic induction heat pipe of the utility model.

Embodiment 1, referring to Fig. 1,2,3,4, selects for use the mild steel seamless steel pipe of soft magnetic materials or sheet material to roll into tube body of heat pipe 1; Make heat conducting element 10 with cast aluminium alloy material, each heat conducting element 10 is made up of a plurality of sheet fence, offer a circular arc intercommunicating pore 8 at an end of heat conducting element 10, being used for thermophore passes through, also offer connecting hole 9 on each heat conducting element 10, a plurality of heat conducting elements 10 can be serially connected by connecting hole 9 and form heat carrier 2, the intercommunicating pore 8 of two adjacent heat conducting elements 10 is that the 180 ° of positive and negative stacks that misplace mutually become heat carrier 2, increase the circulation area flow process of thermophore in heat carrier 2, heat carrier 2 is slight stationary fit with the inwall of tube body of heat pipe 1, if do not design heat carrier 2, only heat thermophore by tube body of heat pipe 1 limited inner surface, flow velocity at thermophore is not less than under the situation of 2 meter per seconds, the intensification effect of thermophore can be not desirable, thereby heat carrier 2 is installed in tube body of heat pipe 1, heat carrier 2 surface of internal cavity are long-pending to be the several times of tube body of heat pipe 1 inner surface, heat carrier 2 can make moment absorb a large amount of heats from tube body of heat pipe 1 inner wall surface, give thermophore with the very large surface area conduction of heat carrier 2 inner chambers heat, thermophore was taken away the heat that tube body of heat pipe 1 produces as much as possible in moment, heat energy is transported in the process equipment that needs; At the fastening thermal insulation layer 3 of the outer round surface of tube body of heat pipe 1, thermal insulation layer 3 twines with common alumina silicate refractory fibre product felt earlier, compresses thickness and is no more than 2 millimeters, twines usefulness unidirectional binding tape 1/2 stack behind one deck with common asbestos packing sheet again, and colligation is firm; Twine a layer insulating 4 outside thermal insulation layer 3, insulating barrier 4 selects for use heat-resisting white powder micarex to be wrapped in outside the thermal insulation layer 3, and seamless overlap joint is firm with the 1/2 stack colligation of Kapton adhesive tape, and surface spraying organosilicon red enamel dries; Twine inductor 5 in insulating barrier 4 outsides, the cross section band Homogeneouslly-radiating sheet of inductor 5 copper conductors, inductor 5 is to adopt air cooling type cross section copper conductor tightly to be wrapped in insulating barrier 4 outsides of heat pipe, the turn-to-turn insulation special-shaped troughed belt of " U " type polytetrafluoroethylene (PTFE), specification and copper conductor cross section are complementary, be used, the two ends of the turn-to-turn of inductor 5 and inductor 5 are fixed, thermal insulation layer 3 is used to protect the insulating properties of outer field inductor 5 to be without prejudice, the heat that as much as possible blocks simultaneously tube body of heat pipe 1 generation conducts to inductor 5, heat pipe thermal insulation layer 3 radially, insulating barrier 4, firm between inductor 5 coils, must not leave the space, loosening, inductor 5 is different designs of watt level according to heat pipe, make full use of electric energy and guarantee the balance of three-phase load, the heat pipe that power is less than normal, adopt the inductor coil of three phase mains, adopt the connection of " Y " type of falling or " △ " type of falling, the heat pipe that power is bigger adopts better simply single-phase induction coil, three phase mains is provided with three heat pipes, it is more powerful that to adopt three heat pipes be one group, can organize parallel connection more, so long as transformer capacity allows, can realize the series of products of many specifications, adopt the copper conductor in air cooling type cross section, with the special-shaped troughed belt insulation of " U " type, the cylindrical of inductor 5 is to expose in air, and available wind is forced cooling; At the outer installation yoke or the ferrite 6 of inductor 5, " Qian " shape yoke retrains the ability maximum that leakage field is outwards dispersed, and fully improves the electrical efficiency of heat pipe; Outer cone surface at the two ends of tube body of heat pipe 1 installs thermal protection layer 7 additional, and promptly heat insulation protective materials can reduce the heat loss of heat pipe, generally adopts common alumina silicate refractory fibre product felt to twine wrapping and forms.
