Abstract
A copper-aluminium composed pipeline structure parts for refrigeration system is characterized in that a segment of a copper pipe is welded on one end or both ends of the aluminum pipe, and the contacting surface of the copper pipe and the aluminum pipe with the same or similar outside diameter is a conical sheathed face with the copper pipe inside and the aluminium pipe outside. The internal diameter 1 of the pipeline that is formed by the conical sheathed surface is the same as or similar to the internal diameter 2 of the aluminium pipe. The utility model has fine welding quality and broad fusion face. The inside and outside pipe diameter at the joint is nearly the same as that of the aluminum pipe although a sleeved joint design is adopted, so as to ensure the refrigerating requirement and the following requirement of the processing structure of the product. Thus, the utility model can be applied to refrigerating pipelines which have high requirement on compaction, cleanness and special requirement on flow volume, inner and outer diameters. Therefore, it can be widely used in the refrigerating products such as air conditioners, refrigerators, refrigerating cabinets, display cases, drinking machines, and desiccating machines and so on.
Description
Technical field
The utility model relates to a kind of new aluminum pipe, copper pipe combination---copper-aluminium combined pipeline for refrigerating system structural member.
Background technique
Refrigeration agent is the operation material that carries out refrigeration cycle in refrigeration plant, and in the circulating pipe system that carries cold medium, refrigeration is relevant with the content of refrigeration agent with refrigeration agent, crosses to exceed to hang down all can not reach best refrigeration.Obviously, in the running, the refrigeration agent in the system reduces, and refrigeration will be affected.Also have, the penetrability defective will cause the refrigeration agent seepage on the tubing or on the soldering point, this defective is impossible self-healing, the refrigeration agent of missing can't be regenerated, even cause the so small defective of leakage quantity 0.5g/ finally all can cause the refrigeration product not freeze, the penetrability defective takes place can only be remedied by the mode of maintenance, is exactly reject for this product of user, is very important so guarantee the compactness of pipeline and contact.
Prior art adopts copper pipe to be inserted into the mode that aluminum pipe welds then, although still can obtain the pipe joint structure of good compactness, because behind the copper pipe undergauge, internal diameter obviously reduces, influenced the flow of refrigeration agent, thereby refrigeration has been produced certain influence; In addition, in some productions,, influenced copper-aluminium combined application because the undergauge of copper pipe causes carrying out expand tube processing such as products such as A/C evaporator and condensers.
Summary of the invention
The purpose of this utility model provides a kind of copper-aluminium combined pipeline for refrigerating system structural member, enlarging application area and the using effect based on the copper aluminum pipe built-up joint structure of aluminum pipe, the pipeline structure spare by the improvement joint structure is to remedy the above-mentioned deficiency of prior art.
Bare bones of the present utility model is to adopt the socket joint type structure in the copper-aluminium tube joint of copper-aluminium combined pipeline, and the faying surface that is about between copper pipe, aluminum pipe is designed to copper at interior, aluminium taper socket welded joint outside, can guarantee the face of weld than broad like this.Wherein the internal diameter φ 1 of joint area equates with the internal diameter φ 2 of aluminum pipe or is close, with the requirement of abundant assurance refrigerant flow and subsequent machining technology.Above-mentioned welded joint can adopt ripe pressure welding technology to obtain.
The utility model is to be welded with one section copper pipe in the one or both ends of aluminum pipe, and the faying surface of identical or close copper pipe of external diameter and aluminum pipe be copper pipe at interior, aluminum pipe taper socket face outside, the pipeline internal diameter φ 1 that this taper socket face constitutes equates with the internal diameter φ 2 of aluminum pipe or is approaching.
Its welding quality of the utility model of constructing thus is good, the fusion face width, although adopted the socket joint type joint structure, the inside and outside caliber of joint can be accomplished basic identical with aluminum pipe, thereby has guaranteed the refrigeration and the following process structural requirement thereof of product.Therefore, the utility model can be used for compactness, turbidity test are required refrigeration pipe high and that flow and inside and outside footpath are had specific (special) requirements.
Description of drawings
The basic schematic representation of Fig. 1 copper aluminum pipe of the present utility model combined pipeline structure.
1 copper pipe, 2 aluminum pipes, 3 taper socket faces wherein.
Embodiment
As Fig. 1, the utility model is to be welded with one section copper pipe 1 in the one or both ends of aluminum pipe 2, and the faying surface of identical or close copper pipe 1 of external diameter and aluminum pipe 2 be copper pipe at interior, aluminum pipe taper socket face 3 outside, the pipeline internal diameter φ 1 that this taper socket face 3 constitutes equates with the internal diameter φ 2 of aluminum pipe 2 or is approaching.
The utility model selects for use the external diameter of copper pipe 1 and the aluminum pipe 2 can be identical, also can be slightly different, thereby the utility model has also overcome the requirement for restriction of conventional method to copper aluminum pipe pipeline material wall thickness.
As Fig. 1, the utility model is to be welded with one section copper pipe 1 in the one or both ends of aluminum pipe 2, form copper-aluminium combined, the faying surface that is characterized in 2 of copper pipes 1, aluminum pipe is a taper socket face 3, and the internal diameter of the internal diameter at taper socket face 3 places and aluminum pipe 2 is basic identical, and not only compactness is good, cost is low, and, the inside and outside diameter of pipeline can be accomplished basically identical, has both improved the Applicable scope of copper-aluminium combined pipeline, has satisfied the requirement of subsequent technique to structure again.
Therefore can be widely used in the refrigeration products such as air conditioner, refrigerator, refrigerator-freezer, show cabinet, drinking machine, dehumidifier.
