Description
Technical field
Heat exchanger is the utility model is related to, it is especially related with a kind of heat exchanger heat pipe connection U-tube.
Background technology
The efficiency of heat exchanger is influenced be subject to its material, structure and application scenarios etc..Heat exchange applied to heat exchanger
Component, plays the role of heat absorption, heat transfer, the heat of fuel gas buring is absorbed by fin, and passes to interspersed copper pipe, is copper
Water heating in pipe, so as to fulfill the hot water effect of water heater.The copper pipe of array, its termination are usually attached by U-tube, real
The connection in existing water route.Existing U-tube connection mode is only simple welding, on the other hand right on the one hand there are unstability
Current smoothness has and necessarily influences, it is necessary to be improved.
Utility model content
The utility model provides a kind of heat exchanger heat pipe connection U-tube, it is intended that solves above-mentioned prior art deficiency, leads to
Cross limiting stand, weldering body groove, weldering body and realize that the perfection with straight copper tube is connected, it is ensured that while connective stability, do not interfere with inside
Current patency, also designs finned sheath, improves the utilization of heat exchanging modular peripheral heat, further improves U-tube performance.
In order to realize the purpose of this utility model, intend using following technology：
A kind of heat exchanger heat pipe connection U-tube, is copper material, it is characterised in that including arc section and be connected to
There are linkage section and circulation section in the flat segments at arc section both ends, flat segments front end, and linkage section internal diameter is more than circulation section internal diameter, linkage section
Limiting stand is equipped with circulation section intersection, is concave weldering body groove on the inside of limiting stand, weldering body groove is interior inserted with annular weldering body, annular
The thickness of weldering body is matched with weldering body well width, limiting stand width and straight copper tube thickness matching to be connected, and is arranged in the middle part of arc section
There is protective metal shell, the fin of array is equipped with the inside of sheath.
The weldering body groove depth is 3 ~ 5mm.
The material of the annular weldering body is identical with welding rod.
The protective metal shell and fin are copper material.
One-to-one air-through holes are equipped with the fin of the array.
The beneficial effects of the utility model are：
U-tube is attached using flat segments and straight copper tube, is specifically, using the annular weldering body being inserted into weldering body groove, with
Limiting stand coordinates, spacing by limiting stand after straight copper tube insertion, is welded and fixed both by welding procedure, connection validity is good；
After the insertion of annular weldering body together with limiting stand space, be just inserted into easy to straight copper tube, assembling matching degree greatly improves；And due to thickness
Degree matching, the internal diameter of straight copper tube forms matched plane with circulation section internal diameter after insertion, does not influence current circulation；Meanwhile also
The sheath that copper inner side is equipped with fins set is added in the middle part of arc section, according to the actual installation situation of U-tube, U-shaped recess
Opposite is the heat-exchanging component or heat exchange module of heat exchanger, and heat exchange module periphery is also in the environment of high-temperature, passes through
The fins set of array can further absorb peripheral high-temperature heat flux, and arc section is passed to by sheath, further improve hot profit
With efficiency, U-tube and the performance on whole copper pipe road are improved.
Brief description of the drawings
Fig. 1 shows the utility model overall structure diagram figure.
Fig. 2 shows the utility model partial view.
Embodiment
As shown in Figure 1 and 2, a kind of heat exchanger heat pipe connection U-tube, is copper material, U-tube 1 include arc section 12 with
And the flat segments 11 at 12 both ends of arc section are connected to, 11 front end of flat segments has linkage section 111 and the section 112 that circulates, in linkage section 111
Footpath is more than circulation 112 internal diameter of section, and linkage section 111 and circulation 112 intersection of section are equipped with limiting stand 13, and the inner side of limiting stand 13 is depression
Weldering body groove 14, inserted with annular weldering body 15 in weldering body groove 14, the thickness of annular weldering body 15 is matched with 14 width of weldering body groove, spacing
13 width of platform and 0 thickness matching of straight copper tube to be connected, the middle part of arc section 12 are arranged with protective metal shell 2, and the inner side of sheath 2 is equipped with battle array
The fin 21 of row.Specifically, 14 depth of weldering body groove is 3 ~ 5mm.The material of the annular weldering body 15 is identical with welding rod.It is described
Protective metal shell 2 and fin 21 are copper material.
U-tube 1 is attached using flat segments 11 and straight copper tube 0, is specifically, and utilizes the annular welds of insertion in weldering body groove 14
Body 15, coordinates with limiting stand 13, spacing by limiting stand 13 after straight copper tube 0 is inserted into, and is welded and fixed both by welding procedure,
