Abstract
The utility model provides a heat transfer tube provided with an inner insertion. The heat transfer tube comprises a tube body, wherein the inner insertion is arranged in the tube body, a gap is arranged between the inner side wall of the tube body and the inner insertion, the inner insertion is a conical tube, the tip of the inner insertion is sealed, the section area of the sealing end of the inner insertion is smaller than that of the opening end of the inner insertion, the sealing end of the inner insertion is located in the tube body, the opening end of the inner insertion is fixedly connected with one end of the tube body through threads, the tube wall of the inner insertion is provided with a plurality of through holes, and the total area of the through holes is smaller than the area of the opening end of the inner insertion. The heat transfer tube has the advantages of being high in heat transfer efficiency and convenient to assemble.
Description
Technical field
The utility model relates to technical field of heat exchangers, particularly a kind of heat-transfer pipe that is provided with plug-in part.
Background technology
The structure of heat exchanger, generally be divided into cast and template two large classes, never breakthrough since the centuries, only be pipe in shape, the decorative pattern of plate innovates in pattern or design, the oval pipe of a collection of what is called, ripple pipe, screw pipe etc. subclass occurs, aspect heat transfer property, do not have much raisings; Take pipe as example, thermal medium heat exchange with tube wall when flowing is carried out in the inboard contact position of thermal medium and tube wall in the pipe, inside thermal medium not with tube wall in the heat transfer medium of side contacts then just in managing, do not flow through with pipe generation heat exchange; The pattern that heat exchange is carried out in thermal medium and tube wall inboard is the relatively poor laminar flow pattern that conducts heat, and the heat transfer medium at heat medium flow middle part to be pattern with turbulent flow flow, its efficient of carrying out heat exchange is higher, but does not participate in heat exchange, has affected heat exchanger effectiveness.
Summary of the invention
The utility model is for the lower problem of thermal medium heat exchanger effectiveness in the heat-transfer pipe that overcomes prior art, provides a kind of and improves the thermal medium heat exchanger effectiveness, and the heat-transfer pipe that is provided with plug-in part simple in structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme, a kind of heat-transfer pipe that is provided with plug-in part, comprise body, be provided with plug-in part in the described body, be provided with the space between described body madial wall and the plug-in part, described plug-in part is the tubular of end sealing, described plug-in part blind end sectional area amasss less than opened end section and is positioned at body, and described plug-in part openend is fixedly connected with body one end, and the tube wall of described plug-in part is provided with some through holes.Body one end that is fixed with the plug-in part openend is body thermal medium entrance, thermal medium enters body from the entrance of body, openend through plug-in part flows to blind end, because plug-in part is integral body from openend to blind end and dwindles shape, after thermal medium enters, must be by the through hole frontal impact heat-transfer pipe inboard wall of tube body on its tube wall, thermal medium and heat-transfer pipe body carry out central collision like this, its heat transfer efficiency is higher, so that the exothermic coefficient of heat-transfer pipe than high 2-4 times of traditional heat-transfer pipe, has improved the heat transfer efficiency of heat-transfer pipe greatly; The openend of plug-in part can be connected with the heat-transfer pipe body by screw thread or rivet, assembles very convenient; Heat-transfer pipe also can many forms heat transmitter side by side, the heat-transfer pipe after side by side, and its air inlet is in parallel, forms the air inlet overall channel, and its gas outlet is in parallel, forms the overall channel of giving vent to anger.
As preferably, described plug-in part is the conical tube of most advanced and sophisticated sealing.At conical tube through hole is set, the axis of through hole can be perpendicular to inboard wall of tube body, can collide inboard wall of tube body by straight line after thermal medium sprays from body, improves rate of heat exchange.
As preferably, the gross area of described through hole is less than plug-in part openend area.Flow was certain when thermal medium flowed, and when the flow path sectional area reduced, flow velocity can increase, and was conducive to thermal medium and body sufficient heat exchange.
In sum, the utlity model has following beneficial effect: 1) improved the heat transfer efficiency of thermal medium in heat-transfer pipe; 2) simple in structure, ease of assembly.
Description of drawings
Fig. 1 is the structural representation that is provided with the heat-transfer pipe of plug-in part
Fig. 2 is Fig. 1 A-A place cross-sectional view
Among the figure: 1, body 2, plug-in part 3, space 4, plug-in part openend
5, plug-in part blind end 6, through hole.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of heat-transfer pipe that is provided with plug-in part, comprise body 1, be provided with plug-in part 2 in the body 1, be provided with space 3 between body 1 madial wall and the plug-in part 2, plug-in part 2 is the conical tube of most advanced and sophisticated sealing, plug-in part blind end 5 sectional areas are less than plug-in part openend 4 sectional areas and be positioned at body 1, plug-in part openend 4 is fixedly connected with by screw thread with body 1 one ends, and the tube wall of plug-in part 2 is provided with some through holes 6, and the gross area of through hole 6 is less than plug-in part openend 4 areas.
Specific implementation process is, thermal medium at first enters in the plug-in part 2 from body 1 and plug-in part openend 4 stiff ends, and flow to plug-in part blind end 5, owing to hindered by 5 sealings of plug-in part blind end, thermal medium sprays to heat-transfer pipe body 1 inwall after the through hole 6 on plug-in part 2 tube walls accelerates, bump with body 1 inwall, produces heat exchange, so that the exothermic coefficient of heat-transfer pipe than the high 2-4 of traditional heat-transfer pipe doubly, has improved the heat transfer efficiency of heat-transfer pipe greatly.
