Description of the Invention: [Technical Field] The present invention relates to a heat conducting device, and more particularly to a double tube heat conducting device. [Prior Art] At present, there are many oil fields that have high viscosity, especially in winter Φ or cold regions. Due to the low temperature, crude oil flows slowly in oil pipelines, and may even block due to stagnation. . In general, the metropolitan area is equipped with heating equipment along the oil pipeline to reduce the viscosity of the crude oil in the door & The heat-conducting device i, which is not conventionally used in Fig. 1, is applied to heat a petroleum-transfer B &2' Each heat conducting group u has a cavity (1) enclosing a vapor space 11 外 outside the oil delivery pipe 2, a liquid storage tank 112 communicating with the cavity 111 and storing the liquid water, and A furnace 113 that generates a flame to heat the Lu liquid reservoir 112. Each of the furnaces 113 is used to heat m in each of the liquid storage cylinders 112 into a 6-warm steam' and then let the high-temperature steam pass through the respective helium chambers 110 to conduct heat to the crude oil around the oil delivery pipe 2. In order to achieve the purpose of reducing the viscosity of crude oil. However, when the heat conducting device is actually used, there are the following disadvantages: However, the heat source is fully utilized, resulting in waste of energy. · Because the high temperature vapor is used to flow through the outer peripheral surface of the oil delivery pipe 2 to achieve direct transmission. Enthusiastic. Since all high-temperature vapors cannot be brought into contact with the oil delivery pipe 2 5 1303304 and condensed into a liquid, high-temperature steam at a high flow rate is usually used as a design criterion to allow excess high-temperature vapor to be discharged. Further, when the high-temperature vapor is condensed into a liquid, it will stagnate and adhere to the petroleum transfer pipe 2, hindering the transfer of the heat 1 so that the heat of the high-temperature steam cannot be completely used, and the above will cause unnecessary waste of energy. First, increase the production cost: because the heat conduction device 1 uses the heated water liquid to generate high temperature steam, therefore, it is necessary to additionally store the water liquid and the pipeline system for transporting the water liquid to supplement the water liquid in the liquid storage tank 112. . Even if there is condensing the southerly vapor into a liquid and recycling it, this will greatly increase the production cost. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a double tube heat conduction device which can effectively utilize a heat source and can rapidly and uniformly heat a fluid flowing therein. Therefore, the double tube heat conduction device of the present invention comprises at least one heat pipe group, the heat pipe group includes an inner pipe, and an outer pipe, the inner pipe has a pipe body segment, and the two pipes are respectively located in the pipe body segment. And an open-ended opening segment, the outer tube has a tubular body surrounding the outer wall surface of the tubular body portion of the inner tube and defining an annular heat transfer space, respectively formed in the tubular body a first and second capillary layer on the wall surface and the outer wall surface of the pipe body segment, and a heat-conducting medium filled in the heat transfer space. When one end of the outer pipe is heated, the inner heat-conducting medium is heated. The tube is quickly heated to the other end of the outer tube, and the tube portion of the inner tube is uniformly heated. The effect of the present invention is that since the evaporated heat transfer medium flows only in the heat transfer 1303304 space, it is not necessary to input an excess heat source, and the second capillary layer 'is utilized to guide the outer wall surface of the pipe body portion condensed on the inner pipe. The heat transfer medium flows to avoid the transmission of the heat-insulating amount, whereby the fluid flowing through the inner tube can sufficiently absorb the heat of the evaporated heat-conducting medium to effectively utilize the heat source and rapidly and uniformly heat the fluid. The above-mentioned and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. As shown in Figures 2 and 3, a preferred embodiment of the double tube heat transfer device of the present invention, in combination with a plurality of electric heating plates 5, can uniformly and rapidly heat a fluid flowing therethrough. When the electric heating plate 5 is supplied with electric current, heat can be generated, and the heat transfer device is used to transfer heat to the fluid. The double tube heat conducting device comprises a plurality of heat pipe groups 3 arranged at intervals, and a plurality of connecting pipes 4 connecting adjacent heat pipe groups 3. In the preferred embodiment, the fluid refers to a liquid having a higher viscosity such as crude oil or petroleum, and the viscosity is lowered by raising the temperature to make it flow smoothly. Each heat pipe group 3 includes an inner pipe 31, an outer pipe 32, two pipe joints 33, and a heat insulating member 34. The inner tube 31 has a tubular body section 3 for eight months - an open section 312 which is open at both ends of the tubular body section 311. Each of the door opening segments 312 is formed with a tapered internal thread 313, which is commonly referred to as a Taper Screw. The outer tube 32 has an outer wall surface surrounding the tubular body portion 311 of the inner tube 3i. A tube body 321 defining a circular heat transfer space 3〇, respectively, 1303304 is formed on the inner wall surface of the tube body 321 and the first and second capillary layers 322 and 323 on the outer wall surface of the tube body segment 311, and A heat transfer medium 324 filled in the heat transfer space 3〇. Both ends of each pipe joint 33 are divided into external threads 331 which are screwed to the inner threads 313 of the inner pipe 31 and which are tapered. The use of the inner and outer snails 3 13 and 33 1 can effectively prevent fluid leakage. Of course, it is also possible to wrap the venting band on the external thread 331 or use a sealing ring to achieve the purpose of reaching the age limit. In actual practice, the pipe joint 3 3 may of course also be formed with internal threads, and the outer pipe 3丨 is screwed into each pipe joint 33 in the form of an external thread. The heat insulating member 34 is coated on the outer peripheral surface of the tubular body 321 of the outer tube 32 to insulate heat from the outer tube 32 to prevent heat from being dissipated. The above-mentioned heat insulating member 34 may be a mica sheet, and of course, an insulating cotton may also be used. In the preferred embodiment, the inner tube 31 and the outer tube 32 are both made of a copper alloy, and the first and second capillary layers 322 and 323 of the outer tube 32 are sintered from copper metal powder of Liling. The hair structure (Wick), but the first, second hair, "field layer 322, 323 may also be a groove-like, mesh-like, or fibrous capillary structure. The inner tube 31 and the outer tube 32 may also It is made of carbon steel, stainless steel, alloy steel, etc., and only needs to cooperate with the heat conducting medium f 324 to avoid incompatibility. In the preferred embodiment, the heat conducting medium 324 is made of inorganic superconductor / The inorganic superconductor used here is a mixture of various inorganic elements. When it is excited, it will rapidly vaporize and rapidly transfer the other end of the k& 32 to achieve a fairly good heat transfer along the heat transfer space. And the average heat effect 8 1303304. The heat transfer medium 324 can also be water, ammonia, methanol, #甲笨, ethanol, or acetone. Different heat transfer medium 324 will have a common temperature range of state, and can Control the degree of temperature rise of the fluid, this part is for body #, green Those skilled in the art can easily use the prior art, and will not be described in detail here. In use, each hot plate 5 is attached to the outer tube 32 of each heat pipe group 3 - The end is called the evaporation end, and the other end is called the condensation end. When each electric heating plate 5 is energized and generates heat, the tube 321 passing through the outer tube 32 transfers heat to the heat transfer space 3〇. When the heat transfer medium Μ* is immediately vaporized and rapidly moved toward the condensing end, during the movement of the heat transfer medium 324, the heat contained therein is absorbed by the inner tube 31, and the inner tube 31 is quickly moved. When the fluid flows through the inner tube 31, if it flows from the condensation end to the evaporation end, the heat of the inner tube 31 can be quickly absorbed to uniformly raise the temperature itself. The heat transfer medium 324 is heated because of the heat. After being sucked away, it gradually condenses into a liquid and falls and adheres to the first and second capillary layers 322 and 323. The heat transfer medium 324 located at the evaporation end is reduced by vaporization, and therefore, the first and second capillary layers 322 can be used. , 323 formed by the capillary force, will be cold The heat medium 324 is pulled back to the evaporation end, and the endothermic evaporation is continued, thereby constituting a % loop to continuously transfer the heat of each of the hot plates 5 to the fluid flowing in the inner tube 31. The second capillary layer 323 can guide the heat transfer medium 324 condensed on the outer wall surface of the pipe body section 311 of the inner pipe 31 to prevent the stagnation and prevent the heat transfer amount from being transmitted. In addition, the hot plate 5 emits heat of 9 1303304. It must be the range of the load of the heat-conducting medium f 324, otherwise it is easy to cause the above-mentioned heat-conducting medium 324 to be vaporized and dry. It is impossible to carry heat efficiently. Also, the electric raft plate 5 of the The input power does not need to be rounded in an excessive manner (compared to the conventional practice, it is necessary to input excessive high-temperature steam), which can effectively save energy and avoid unnecessary power consumption. As shown in Fig. 4, and in conjunction with Fig. 3, the double tube heat conduction device of the present invention can also be used with a single electric heating plate 5 to constitute a water heater for heating water. In FIG. 4, each of the heat transfer tubes 3 of the double tube heat conducting device is vertically spaced apart. The electric heating plate 5 is in an upright contact with each of the outer tubes 32, and each connecting member 4 is also U-shaped. In order to connect each pipe joint 33, water can be sequentially passed through each inner pipe 31 to achieve rapid and uniform heating. Referring back to Figures 2 and 3, it can be seen from the above description that the double tube heat conduction device has the following advantages: 1. Effective use of heat source can avoid unnecessary waste of energy · Due to the electric heating plate 5 The heat must be within the design range of the double tube heat conduction device, and the vaporized heat conduction medium 324 flows only in the heat transfer space 3〇, and does not flow to the outside, and at the same time, utilizes the outer tube 32 The second capillary layer 323 is configured to guide the heat transfer medium 324 condensed on the outer wall surface of the pipe body section 311 of the inner pipe 31 to avoid the transmission of the heat-insulating amount, and effectively apply the heat of the electric heating plates 5 without The known practice is to input excessive amounts of high-temperature steam to save energy and avoid unnecessary power consumption. Second, the production cost is saved: since the heat conduction medium 324 can be evaporated and condensed without circulating in the 10 1303304 heat transfer jade 3G, the heat conduction 324 does not have the problem of dissipation, therefore, It is necessary to add a device for storing water and a piping system for transporting water and liquid, thereby saving the cost of purchasing equipment. Third, construction and maintenance are relatively convenient and safe: since it is only necessary to electrically connect the electric heating plate 5 such as Kouhai with the covered wire, the construction is much more convenient than assembling the rigid metal pipe fittings, and the cost is more economical. Moreover, it does not need to use any liquid fuel, and there is no danger of explosion. It is convenient and safe in construction and maintenance. - In summary, the double tube type I thermal assembly 4 of the present invention utilizes the second capillary layer 323 of each outer tube 32 to guide the heat transfer medium 324 & condensed on the outer wall surface of each inner tube η to avoid The stagnation stops the transmission of the heat insulation amount, and at the same time, 'because the evaporated heat transfer medium 324 flows only in the heat transfer space%', it is necessary to input an excess heat source, thereby allowing the fluid flowing through the inner tube 可 to be The heat of the evaporating heat is fully absorbed to effectively heat the fluid and quickly and uniformly heat the fluid. In addition, "the cost is quite helpful, and the construction and maintenance are relatively convenient, and the safety of the eight can indeed achieve the purpose of the present invention. The above mentioned by Wang Huai is only the preferred embodiment of the present invention, The scope of the present invention can be limited thereto, that is, the simple equivalent change and the repairing result according to the scope of the invention and the scope of the invention are included in the scope of the present invention.
