Specific embodiment
Several illustrative embodiments shown in below with reference to the accompanying drawings describe the principle and spirit of the invention.It should
Understand, describe these embodiments just for the sake of make those skilled in the art can better understand that in turn realize the present invention,
And this scope of the present invention is not limited in any way.
Firstly the need of explanation, heat-exchange device provided in an embodiment of the present invention can be applied in any need to ring
In the scene that border or medium are cooled down or heated.Including but not limited to thermoelectricity, factories and miness, food medical treatment, mechanical light industry, automobile
The fields such as manufacture, civil buildings, the condenser of gas heater, condensing boiler, refrigeration.
Referring to FIG. 1, heat-exchange device provided in an embodiment of the present invention, including tube body 1,1 inside and or outside of tube body are used
Pass through in for heat exchanging fluid.Multiple grooves 2 are evenly distributed with along circumferential surface on 1 outer wall of tube body.Groove 2 is to the inside of tube body tube wall
Recess, so that the tube wall of 2 position of groove is thinner compared to other positions.On the one hand the design of groove 2 makes tube wall
Area compared to 2 Shi Geng great of groove is not provided with, increase heat exchange area, on the other hand but also pipe thickness is smaller, subtract
Light weight.In addition to this, groove 2 also acts the effect of similar reinforcing rib, increases the geometry intensity of tube body 1.Groove 2
Shape can use a variety of geometries, and cross section can be semicircle, triangle, trapezoidal, rectangular etc..
Groove 2 shown in fig. 1 can also be replaced with completely or partially to 1 outer exterior wall of tube body boss outstanding (in figure not
Show), the effect of boss and groove are essentially identical, it may have the effect for increasing heat exchange area, reinforcing geometry intensity, difference are
Boss will not make tube wall become thinner.
Entire tube body 1 can pass through the more pieces of connection of section of jurisdiction 101 compositions.Connect if it is hardness and heat resistance steel or stainless steel
Mode is connect as welding, if it is hardness low copper or aluminium, then directlys adopt one-pass molding, pressure injection or drawing modeling.Shown in fig. 1 is two
A semicircle section of jurisdiction 101.Two sections of jurisdiction 101 after docking, at docking inside and outside be constructed with difference, embody
: two sections of jurisdiction 101 extend towards the inside of tube body in junction, are respectively formed two inclined-planes, two inclined-planes are in tube body 1
Portion links together, and material is thus formed a recess 5 from 1 outside of tube body inwardly.This recess 5 is in tube body 1
The part of side is plane 51, forms the section of V-type.It is curved surface 52 in the part close to 1 outside of tube body, forms similar to recessed
The semicircular structure of slot 2.By adopting such a design, link position is not on the outside or surface of tube body 1, but is located at interior
Side, and curved surface still can be designed to close to the part in 1 outside of tube body, heat-transfer surface is increased in the case where not influencing connection
Product.Binder 53 (such as solder) can be filled in the V-type groove part of the composition of plane 51, and finally formed tie point can peace
The outermost end in face 51 is concordant, or slightly protrudes.
The fin 3 connected with 1 inner wall of tube body is provided in the inside of tube body 1, these fins 3 can be in manufacture section of jurisdiction 101
When and section of jurisdiction 101 be integrally formed (as using casting method).Fin 3 can have multiple groups, be in the width direction in tube body 1
Parallel equidistantly distributed.The surface of each fin 3 has equally distributed burr 301, and burr 301 is either stand in fin 3
Surface on (extend towards the direction in the outside of fin 3, as shown in Figure 1), be also possible to extend inwardly and (not show in figure
Out).The increase of fin 3 takes full advantage of the space of tubular body, so that heat exchange area further increases.Burr on fin 3
301 can increase the surface area of fin 3 again, further increase heat exchange efficiency.The shape of burr 301 can be triangle, ladder
Shape or other rules or irregular shape.
Multiple tracks ring muscle 4 is also constructed along the axial direction of 1 outer wall of tube body, the cross section of ring muscle 4 can be a variety of geometries,
Such as semicircle, triangle, trapezoidal.Ring muscle 4 can also be recessed either relative to tube wall protrusion relative to tube wall.Ring muscle 4
On the one hand it can play the role of increasing by 1 intensity of tube body, on the other hand also increase heat exchange area, improve heat exchange efficiency.
Above-mentioned heat-exchange device can make to obtain by following method:
Step 1: the section of jurisdiction for forming tube body is made.The quantity of section of jurisdiction is at least two panels, can be using the one such as casting
Molding mode makes.The internal structure external structure of entire tube body is preferably axisymmetric, in this way when use two panels section of jurisdiction, can incite somebody to action
Two panels Segment design does not have to consider the problems of to match in splicing at duplicate.As shown in figure 3, two panels section of jurisdiction 101 is existed
Spliced stitching portion 6.
Step 2: each section of jurisdiction is spliced according to corresponding positional relationship.Ensure when splicing:
1, each components, which combine, cannot must securely stomata；
2, tooling fixture must be used when Combined machining, guarantees the identity and interchangeability of product；
3, the tube body after combining must assure that certain geometric accuracy and visual impression；
Step 3: being attached stitching portion, and the tie point after connection is convex relative to the planar section outer end of the recess
It rises or maintains an equal level.
Heat-exchanger rig provided by the invention can be applied to the various occasions for needing to exchange heat.For example, can be used as boiler
Heat exchanger tube or flue gas condensing pipe use, and the flue gas after boiler combustion enters in tube body and tube body and fin sufficiently exchange heat, and change
In thermal process, vapor forms condensed water, flows down along tube wall and fin, while condensed water can carry small of some nocuousness secretly
Grain object, sulfur dioxide, nitrogen oxides etc., are discharged, further purifying smoke together.Vapor is that smoke evacuation forms the main of " white "
Factor, so can also play flue gas by removal vapor and take off white effect
Specific case used herein elaborates inventive concept, the explanation of above example is only intended to
Help understands core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this
Under the premise of inventive concept, any obvious modification, equivalent replacement or the other improvements made should be included in the present invention
Protection scope within.
