Abstract
The utility model relates to a welding seam free transition tube arranged between a dry filter of a miniature refrigeration device and a capillary, which belongs to the technical field of a heat exchange device. The welding seam free transition tube arranged between a dry filter of a miniature refrigeration device and a capillary comprises a thin tube and a thick tube; one end of the thin tube and one end of the thick tube are respectively provided with tube expansion segments, and the other end of the thick tube and the other end of the thin tube are connected by a tapered section; the tapered segment, the thin tube and the thick tube form a whole body. The utility model solves the problems that false welding exists at times, refrigerant leaks caused by gaps of the false welding, dirt storing points are easy to form at a dead angle of a welding point to cause an entire pipeline to be difficult to clean, gap dead angles are formed on the inner wall of a tube, the circulation of the refrigerant is disadvantageous, etc. in an existing welding transition tube in the prior art. The utility model has the characteristics that the refrigerant is not easy to leak, the entire pipeline is easy to clean, the refrigerant is easy to pass through, etc.
Description
Technical field
The utility model relates to a kind of small-type refrigeration appliance device for drying and filtering and intercapillary transition conduit of being arranged at, and belongs to the technical field of heat-exchange apparatus.
Technical background
In electrical equipment such as refrigerator, refrigerator, use cold-producing medium in associated components and metallic conduit, to circulate constantly to carry out heat exchange and reach refrigeration.Connect an end pipeline between device for drying and filtering on the circulation canal and the capillary, be referred to as transition conduit usually.Transition conduit all adopts two thicknesses, the different copper pipe solder flux of state to form in the prior art.During production, earlier two copper pipes are cut fixed length, socket mutually after the reaming connects with silver solder and scaling powder gas welding.The welding slag that soldering forms is difficult to clean, and easily forms source of corrosion, has reduced the service life of copper pipe.The difference of the penetration degree of silver solder and the length of socket can't intuitive judgment, so form following shortcoming easily: 1, have rosin joint often, its space causes cold-producing medium to leak; 2, the weld dead angle easily forms the Tibetan stain, makes integrated piping be difficult to clean; 3, inside pipe wall forms the dead angle, slit, is unfavorable for the circulation of cold-producing medium.
Summary of the invention
The utility model has solved that prior art welding transition pipe exists exists rosin joint often, its space causes cold-producing medium to leak, the weld dead angle easily forms the Tibetan stain, make integrated piping be difficult to clean, inside pipe wall forms the dead angle, slit, is unfavorable for the problems such as circulation of cold-producing medium, provides a kind of and has been difficult for causing cold-producing medium to leak, integrated piping is easy to clean, and what be beneficial to the cold-producing medium circulation is arranged at device for drying and filtering and intercapillary transition conduit.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise tubule and extra heavy pipe, this tubule and extra heavy pipe have an end to be provided with the expander section respectively, described extra heavy pipe is connected by conical section with the tubule other end, and described conical section, tubule and extra heavy pipe are an integral body.During making, elder generation on special machine for shrinking, makes copper pipe the one end attenuate and is in hard attitude situation to be beneficial to be connected the effect of playing throttling and noise reduction in the refrigeration with capillary, and the copper pipe other end still keeps soft state, is connected with device for drying and filtering to be easy to bending; Between its big small diameter tube with the cone form as seamlessly transitting; Reach the designing requirement of electrical equipment transition conduit such as refrigerator, refrigerator afterwards again through other process distortions.Adopt the transition conduit of tubule, extra heavy pipe and conical section one, the weldering leakage that causes because of welding and the corrosion of soldering flux have been stopped, overcome cover weldering the causing endoporus sudden change between former extra heavy pipe and tubule, formation to little latus rectum one end cone smooth transition region, helps the circulation of refrigerant by big latus rectum; The Tibetan stain that does not have the weld dead angle to form makes integrated piping be easy to clean, and has improved inside pipe wall cleannes index, has improved the q﹠r of product on the whole.Simultaneously, the utility model can be fit to the combination of various refrigerator transition conduit different tube diameters by the control of former caliber size and elongation back tubule caliber.
As preferably, tapering α=5 of described conical section °-20 °, the tapering of described conical section reasonable value more is α=8 °-17 °.
Therefore, the utlity model has and be difficult for causing cold-producing medium to leak, integrated piping is easy to clean, and is beneficial to characteristics such as cold-producing medium circulation.During making, elder generation on special machine for shrinking, makes copper pipe the one end attenuate and is in hard attitude situation to be beneficial to be connected the effect of playing throttling and noise reduction in the refrigeration with capillary, and the copper pipe other end still keeps soft state, is connected with device for drying and filtering to be easy to bending; Between its big small diameter tube with the cone form as seamlessly transitting; Reach the designing requirement of electrical equipment transition conduit such as refrigerator, refrigerator afterwards again through other process distortions.Adopt the transition conduit of tubule, extra heavy pipe and conical section one, the weldering leakage that causes because of welding and the corrosion of soldering flux have been stopped, overcome cover weldering the causing endoporus sudden change between former extra heavy pipe and tubule, formation to little latus rectum one end cone smooth transition region, helps the circulation of refrigerant by big latus rectum; The Tibetan stain that does not have the weld dead angle to form makes integrated piping be easy to clean, and has improved inside pipe wall cleannes index, has improved the q﹠r of product on the whole.Simultaneously, the utility model can be fit to the combination of various refrigerator transition conduit different tube diameters by the control of former caliber size and elongation back tubule caliber.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is I place enlarged diagrams of accompanying drawing 1.
Specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, transition conduit is by connecting tubule 1 capillaceous, the extra heavy pipe 3 that connects device for drying and filtering constitutes with the conical pipe 2 that is connected tubule 1 and extra heavy pipe 3, the other end of tubule 1 is provided with the expander section that is connected with capillary, and the other end of extra heavy pipe 3 is provided with the expander section that is connected with device for drying and filtering.Wherein, the tapering of conical pipe is 11 °.
During making, elder generation on special machine for shrinking, makes copper pipe the one end attenuate and is in hard attitude situation to be beneficial to be connected the effect of playing throttling and noise reduction in the refrigeration with capillary, and the copper pipe other end still keeps soft state, is connected with device for drying and filtering to be easy to bending; Between its big small diameter tube with the cone form as seamlessly transitting; Reach the designing requirement of electrical equipment transition conduit such as refrigerator, refrigerator afterwards again through other process distortions.
