Abstract
The utility model discloses a heat exchange tube structure comprising heat exchange tubes, an elbow, and filler. One end of each heat exchange tube is provided with a heat exchange tube flared orifice; two ends of the elbow are provided with open ends; the open ends can be inserted into the heat exchange tube flared orifices; the filler is fixed to the outer walls of the open ends; the filler is used for filling at least part of gaps between the heat exchange tube flared orifices and the elbow inserted into the heat exchange tube flared orifices. The heat exchange tube structure has the advantages that uniform filling of solder during welding after fusion is guaranteed, the solder never flows down to the inner walls of the heat exchange tubes, and normal operation of a refrigerating system is ensured accordingly.
Description
Technical field
The utility model relates to a kind of heat exchange tube structure, a kind of heat exchange tube structure that particularly refrigeration is used.
Background technology
At present, the heat exchanger tube that refrigerating field is used and the connected mode of elbow are that elbow is directly inserted in heat exchanger tube enlarging and welded.This normal welding mode, be difficult to guarantee fills after solder fusing evenly during welding, and scolder is easy to toward downstream to heat exchanger tube inwall, thereby has affected the normal work of refrigeration system, has also wasted scolder simultaneously.In addition, if scolder for a long time under cold-producing medium high temperature and high pressure environment, it more easily comes off and injures compressor.Moreover in order to guarantee the even of weld, welder will strictly control the duration and degree of heating, otherwise duration and degree of heating control is bad, will burn and lacks and waste raw material, and this has also proposed higher requirement to welder's technology.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Utility model content
The purpose of this utility model is to provide a kind of heat exchange structure, thereby overcome the scolder existing in prior art, melts the rear shortcomings such as inhomogeneous and scolder inflow heat exchanger tube inwall impact refrigeration of filling.
For achieving the above object, the utility model provides a kind of heat exchange tube structure, comprising: heat exchanger tube, and its one end has heat exchanger tube enlarging; Elbow, its two ends have openend, and openend can insert heat exchanger tube enlarging; And the filler that is fixed on the outer wall of openend, it is used for filling heat exchanger tube enlarging and inserts at least part of space forming between the elbow of heat exchanger tube enlarging.
Preferably, in technique scheme, the pipe interior diameter of heat exchanger tube enlarging is greater than the pipe interior diameter of elbow, to form space.
Preferably, in technique scheme, the manufactured materials of heat exchanger tube and elbow is copper.
Preferably, in technique scheme, filler is copper wire, and copper wire is around the outer wall formation cyclic structure of openend.
Compared with prior art, the utlity model has following beneficial effect:
When heat exchange tube structure of the present utility model has guaranteed welding, after solder fusing, fill uniformly, and can be toward downstream to heat exchanger tube inwall, and then guaranteed the normal work of refrigeration system.
Accompanying drawing explanation
Fig. 1 is according to the top view of scavenge trunk structure of the present utility model.
Fig. 2 is according to the cutaway view of scavenge trunk structure of the present utility model.
Fig. 3 is according to the partial enlarged drawing of the cutaway view of scavenge trunk structure of the present utility model.
Main description of reference numerals:
1-heat exchanger tube, the enlarging of 11-heat exchanger tube, 2-elbow, 3-filler.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or part, and do not get rid of other element or other part.
As shown in Figure 1 to Figure 3, according to a kind of heat exchange tube structure of the utility model, comprising: heat exchanger tube 1, elbow 2 and filler 3.
One end of heat exchanger tube 1 has heat exchanger tube enlarging 11, and heat exchanger tube is preferably two.The two ends of elbow 3 have openend, and openend can insert respectively two heat exchanger tube enlargings 11.The pipe interior diameter of heat exchanger tube enlarging 11 is greater than the pipe interior diameter of elbow 2, to form space, is convenient to welding.The manufactured materials of heat exchanger tube 1 and elbow 2 is copper.Heat exchanger tube 1 is preferably hollow light facial canal, elbow 2 is preferably U-shaped hollow light facial canal, but it is not limited to this, and the thinkable shape of any those skilled in the art all can fall into protection domain of the present utility model.
The material of filler 3 is copper wire, thereby copper wire is looped around and on the outer wall of openend, forms cyclic structure.The filler 3 of cyclic structure is fixed on the outer wall of openend, and this filler is used for filling heat exchanger tube enlarging 11 and is inserted at least part of space between the elbow 2 of heat exchanger tube enlarging 11.During welding, the cyclic structure that this filler 3 forms has effectively stoped stream in scolder, thereby has guaranteed the normal work of refrigeration system.
The aforementioned description to concrete exemplary of the present utility model is for the object with illustration is described.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present utility model and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present utility model and various selection and change.Scope of the present utility model is intended to be limited by claims and equivalents thereof.
