Abstract
The invention discloses a hot pin capable of avoiding hot reflux, which is provided with a condensation zone, an evaporation zone and a ceramic zone, wherein the ceramic zone is of a tubular structure which is prepared by a high-intensity ceramic material and the ceramic zone is fixed between the condensation zone and the evaporation zone; and the condensation zone is communicated with the upper part of the ceramic zone by adhesive bonding and the evaporation zone is communicated with the lower part of the ceramic zone by adhesive bonding. The hot pin capable of avoiding hot reflux of the invention has simple structure; and when in use, the ceramic zone has heat insulation effect, after the heat quantity is released to the condensation zone from the evaporation zone by metal clapboards, the heat quantity can not be conducted downwards along a ceramic tube wall and the heat quantity returns to the evaporation zone so as to generate hot reflux, thereby being capable of avoiding the hot reflux, improving the radiating efficiency of the hot pin, and being suitable for all hot pins.
Description
Technical field the present invention relates to a kind of hot pin, especially can avoid the hot pin of hot reflux.
The background technology hot pin is centreless gravity type heat pipe or thermal siphon again, is made up of the steel pipe of a sealing, and the inside is filled with liquid nitrogen or other working medium, and radiator shutter is equipped with on the top of steel pipe, is referred to as condensation segment, places atmosphere; The bottom of steel pipe is imbedded in the ground ever-frozen ground, is called evaporator section.When having the temperature difference, the heat absorption of the liquid nitrogen of evaporator section flashes to gas, and the pipe internal pore rises to condensation segment in draught head effect lower edge, is condensed into liquid, and under the gravity effect, flows down along tube wall.Circulation is transferred to the heat in the stratum in the atmosphere and so forth, thereby reduces the ground temperature of ever-frozen ground, melts to prevent ever-frozen ground, thereby reaches stable road bed purpose.
But, there is such problem in the use of current hot pin: condensation segment and evaporator section form by high-intensity metal manufacturing, coefficient of heat conduction height, so after heat is discharged into condensation segment from evaporator section, can get back to evaporator section along metal pipe-wall conduction downwards, cause hot reflux.Hot reflux directly influences the radiating efficiency of hot pin.
Chinese patent CN2614225 number disclosed " a kind of stable complex hot pin of frozen soil that keeps " patent (application number: 03211128.2), in used heat rod endotherm section body, be inserted with the minor diameter hot pin of another root external diameter, be provided with filler between the two less than used heat rod internal diameter of tube body.Chinese patent CN2589923 number disclosed " keeping the stable hot pin of frozen soil " patent (application number: 02292154.0), its the outside be coated with anticorrosive coat in have the heat pipe top of heat-transfer working medium to be provided with the lifting detent mechanism, establish the fin that is coated with anticorrosive coat on the radiating segment of this heat pipe; Near the boundary of the radiating segment of hot pin and evaporator section, be provided with label; Be provided with heat-insulation layer in one section heat pipe anticorrosive coat of label bottom; The skin of fin combined anti-corrosion layer is for reducing the material layer that absorbs solar radiant heat; Be provided with monitor control mechanism at the hot pin radiating segment; Preferably the radiating segment heat pipe is the arm arranged side by side that respectively carries fin that is connected with the heat pipe body.The weak point of these two patents is: can both strengthen the resistance to corrosion of hot pin, but still not solve the hot reflux problem.In addition, do not retrieve the documents and materials more approaching with this patent.
On the other hand, the development of special cermacis is quite rapid.High-strength ceramic, low temperature resistant, high pressure has identical expansion and contraction property with steel.Special cermacis has been widely used in aerospace industry, atomic energy industry, mechanical industry, steel and iron industry, as heat-barrier material of ceramic engine, sintex, high speed ceramic bearing, command bundle rods for nuclear reactors, spacecraft or the like.
Summary of the invention purpose of the present invention is exactly that a kind of hot pin that can avoid hot reflux will be provided, and avoids hot reflux, improves the radiating efficiency of hot pin.
In order to achieve the above object, the hot pin that can avoid hot reflux provided by the invention also has the pottery section, wherein except having condensation segment and evaporator section, the pottery section manufactures tubular structure by high-intensity ceramic material, and the pottery section is fixed between condensation segment and the evaporator section; Condensation segment is connected with pottery section top by bonding, and evaporator section is connected by bonding and ceramic pars infrasegmentalis.When the present invention uses because pottery section has effect of heat insulation, so after heat is discharged into condensation segment from evaporator section by metal partion (metp), can't be again along ceramic vessel wall conduction downwards and get back to evaporator section, cause hot reflux.
The hot pin of hot reflux of can avoiding provided by the invention has positive effect: except having condensation segment and evaporator section, also have the pottery section, and simple in structure; During use, because pottery section has effect of heat insulation, so after heat is discharged into condensation segment from evaporator section by metal partion (metp), can't get back to evaporator section and cause hot reflux along ceramic vessel wall conduction downwards again, therefore can avoid hot reflux, improve the radiating efficiency of hot pin, be applicable to all hot pins.
Description of drawings the present invention will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression schematic diagram of the present invention.
Structure shown in the accompanying drawing 1 comprises: top 1, condensation segment 2, pottery section 3, bottom 4, evaporator section 5.
The specific embodiment hot pin of hot reflux of can avoiding provided by the invention is except having condensation segment 2 and evaporator section 5, also has pottery section 3, wherein, pottery section 3 manufactures tubular structure by high-intensity ceramic material, and pottery section 3 is fixed between condensation segment 2 and the evaporator section 5; Condensation segment 2 is connected with pottery section 3 tops 1 by bonding, and evaporator section 5 is connected with pottery section 3 bottoms 4 by bonding.When the present invention uses because pottery section 3 has effect of heat insulation, so after heat is discharged into condensation segment 2 from evaporator section 5 by metal partion (metp), can't be again along ceramic vessel wall conduction downwards and get back to evaporator section 5, cause hot reflux.
Protection domain of the present invention relates to all changes form recited above.
