Detailed description of the invention
The heat exchanger of a kind of specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.But, the present invention should be understood as and be not limited to this embodiment described below, and technical concept of the present invention can combine with other known technologies or function other technologies identical with those known technologies and implements.
In the following description, in order to clear displaying structure of the present invention and working method, to be described by many Directional words, but by the Word Understanding such as "front", "rear", "left", "right", " outward ", " interior ", " outwards ", " inwardly ", " axis ", " radial direction " for convenience of term, and word of limitation should do not should be understood to.Wherein " interior " should be understood to the direction near axis, accordingly, should be understood to the direction away from axis outward.
The object of the present invention is to provide and to be a kind ofly made up of basic module, can arbitrary shape be realized and be applicable to the heat exchanger of any environment.This heat exchanger can also effectively overcome in prior art the technical barrier being difficult to clean.
Fig. 1 is the structural representation of heat exchanger involved in the present invention.As shown in Figure 1, this heat exchanger is a two-tube tubing heat exchanger.This heat exchanger comprises outer tube 10 and interior pipe 20.Wherein interior pipe 20 is concentrically inserted in the inwall of outer tube 10.Fig. 2 is the AA sectional view of heat exchanger involved in the present invention.Form a runner between interior pipe 20 and outer tube 10, interior pipe 20 itself is by being another runner 40.Two runners are isolated from one another by interior pipe 20, only realize heat exchange, and do not come in contact.
Interior pipe 2 and outer tube 10 constitute a heat exchanger, and the head and the tail two ends of this heat exchanger respectively connect a cross over pipe 50.As shown in Figure 4, cross over pipe 50 is preferably a kind of three-way pipe.Three ends all can be connected with heat exchanger, thus this two-tube tubing heat exchanger can become three-dimensional structure from the straight line of plane, is satisfied with arbitrary field of employment.
As shown in Figure 5, a of cross over pipe 50 end coordinates with the outer surface of the outer tube of heat exchanger, fit system can be threaded, thermal welding, the connection such as fluid sealant.The inner tube length of this heat exchanger is slightly longer than outer tube, and therefore, pipe 20 has extended to the c end of cross over pipe, and the runner therefore between pipe 20 and outer tube 10 becomes the runner between interior pipe 20 and cross over pipe.An isolated tube 30 is had between the c of interior pipe 20 and cross over pipe holds.The inner surface of isolated tube 30 is close to the outer surface of interior pipe, and the outer surface of isolated tube 30 is close to the inner surface of the c end of cross over pipe, and therefore clean air or liquid can only flow to b end from a end of cross over pipe, and can not hold to c.By the mutual linking of several cross over pipes and heat exchanger, the heat reclamation device of arbitrary shape can be realized.
Symmetric figure or zhou duicheng tuxing centered by the cross section of interior pipe 20.Fig. 2 is wherein a kind of embodiment, and under this embodiment, pipe 20 is made up of the projection of some center radiation shapes, and the sectional view of interior pipe 20 can be considered as a N limit shape.Fig. 3 is another kind of embodiment.It will be appreciated by those skilled in the art that the span of N can be selected according to actual needs, when the numerical value of N is larger, the area of heat exchange is also larger.Heat exchanger provided by the present invention, clean air or liquid flow through from the runner between interior pipe and outer tube, and carry the waste gas of a large amount of heat energy or waste water flows through from the runner that interior pipe 20 inwall is formed.By interior pipe is designed to centrosymmetric image or zhou duicheng tuxing, inner pipe wall easy cleaning can be made.Arbitrary section due to inwall is all shape about the same, therefore any one limit of interior pipe is all almost parallel with axis, therefore can stretch in interior pipe with the scrub-brush of common common long handle, rotate or move up and down hairbrush and by frictional force, dirt can be removed.
Fig. 4 is the 3rd embodiment of heat exchanger provided by the present invention.Compared with the one the second embodiments, the cross section of the interior pipe in the 3rd embodiment is similarly a centrosymmetric image or zhou duicheng tuxing, but its jut rotates by certain angle, forms a helical form figure.
Interior pipe 20 is made up of aluminium, copper, silver-colored contour thermal conductive metallic material, is preferably extruded aluminium alloy extrusions, and like this, the tube wall of pipe can be accomplished very thin, and processing technology is relatively simple.Outer tube 10 can be made up of the material that the thermal conductivity factors such as calcium silicates, fibre cement, quartz sand, plastic raw materials are low.Those skilled in the art also can by outer tube 10 metal material manufacture, outer surface covering and heat insulating layer.Same, isolated tube 30 is also made up of the material that heat conduction is low.
Fig. 6 is a kind of working state schematic representation of heat exchanger involved in the present invention.As shown in Figure 6, this heat exchanger has been used on Hopper Dryer.Hopper Dryer utilizes metallic resistance silk to add hot-air, and utilizes a blower fan that hot-air is blown into Hopper Dryer inside by airduct, thus realizes the drying of material.This Hopper Dryer comprises blower fan 1 and an air outlet 2.Blower fan 1 is inner by the air heat after-blow material bin of fresh drying, and air outlet 2 discharges the waste gas with a large amount of heat energy and steam.Waste gas and fresh air realize heat exchange after this heat exchanger, and the heat energy in waste gas is conducted to after in fresh air and is discharged.Except Hopper Dryer, heat exchanger provided by the present invention can also be applicable in the plurality of devices such as smelting stove, hot water apparatus, aircondition, oil cooler.
Compared with prior art, the invention has the advantages that: without any contact point between two runners of the first, this heat exchanger, clean gas/liquid can not be caused by waste gas/waste liquor contamination.The second, its structure is simple, is made up of, can realizes arbitrary shape and be applicable to any environment basic module.Three, manufacturing process simply, therefore manufacturing cost decline more remarkable in prior art.Four, easy cleaning, will cause heat exchanger effectiveness to decline because of long-term accumulation dirt.
Just preferred embodiment of the present invention described in this description, above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art, all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
