Abstract

The utility model relates to a plate finned tube type radiator with a pipeline in a copper-aluminum composite structure, which improves the existing plate finned tube type radiator and is composed of the pipeline for flowing refrigeration medium and fins inserted on the pipeline. The utility model is characterized in that the pipeline is composed of a pipeline body in the copper-aluminum composite structure with a plurality of copper U angle heads and copper pipe interfaces welded with the angle heads. Both ends of the pipeline body in the copper-aluminum composite structure are provided with copper pipe interfaces used for connecting with aluminum pipes, and an inserting mode is adopted in the connection mode of the copper pipe and the aluminum pipe of the pipeline body in the copper-aluminum composite structure so as to obviously reduce the manufacturing cost of the utility model.

Description

Pipeline is the nest plate tube radiator of copper aluminum pipe composite construction
Technical field
The utility model relates to the nest plate tube radiator that is used for refrigeration product, and the pipeline of this nest plate tube radiator adopts the copper aluminum compound structure, and promptly pipeline is the nest plate tube radiator of copper aluminum pipe composite construction.
Background technology
Nest plate tube radiator (as A/C evaporator and condenser) is that being widely used in the cold-producing medium is in the refrigeration product of refrigerant with the surface radiating device of the outer coefficient of heat transfer of nest plate enhanced tube.In running, rely on the phase transition process of nest plate tube radiator pipeline inner refrigerant gas-liquid attitude to absorb or distribute heat, in circulating pipe system, refrigeration is relevant with the quantity of cold-producing medium, cold-producing medium too much or reduce and all can influence refrigeration, the seepage that causes because of technological reason in the pipeline will reduce the quantity of cold-producing medium, finally will lose the refrigerating capacity of refrigeration product, system's seepage is the critical defect of this series products.In existing nest plate tube radiator, refrigeration pipe is to be made of a large amount of copper pipes, need in the production to One's name is legion joint weld, the automatic gas brazing that can weld the dense copper pipe joint simultaneously is the mode of optimum nest plate tube radiator copper pipe welding.For above-mentioned reasons, although copper pipe is the precious metal material, the nest plate tube radiator adopts the unique selection of copper pipe as piping material always.A large amount of copper pipes that use cause radiator cost height.And adopt complete aluminum pipe structure, then be faced with many difficult problems that numerous aluminium tube joints weld simultaneously, as brazing flux to intensity, the technological temperature of the compactness of the pollution problem in managing, welding point and weld seam fragility tissue problem such as insoluble such as narrow.
Change the pipeline in the nest plate tube radiator into copper aluminum pipe complex structure body, adopt aluminum pipe promptly, the structure of pipe end compound copper pipe interface, at this moment, the form and the welding method of joint remain unchanged between copper aluminum composite pipes road copper pipe interface and the copper U elbow, just can guarantee that the whole compactness of nest plate tube radiator does not reduce as long as guarantee the compound quality of copper aluminium, and it manufactures instinct and obviously reduces.
Summary of the invention
The purpose of this utility model is to use aluminium in the middle of the full copper pipe pipeline with existing nest plate tube radiator changes into, port is the copper aluminum composite pipes line structure of copper pipe, it is the nest plate tube radiator of copper aluminum composite pipes line structure that a kind of pipeline is provided, so that both guaranteed quality, can reduce material cost greatly again.
The utility model is the improvement to existing nest plate tube radiator, form by the pipeline of circulation refrigerant and the fin that interts on this pipeline, it is characterized in that a plurality of copper U of aforementioned tube route elbow (being the U-shaped copper elbow) constitutes with the copper aluminum compound structure pipeline body that welds mutually with it, the copper pipe interface is arranged, this copper aluminum compound structure pipeline body is that two ends have the copper pipe interface, be connected with aluminum pipe therebetween, the copper aluminum pipe of this copper aluminum compound structure pipeline body connects into copper aluminium composite weld.
Description of drawings
Fig. 1 the utility model basic structure (part) schematic diagram.
Fig. 2 is the A portion enlarged drawing of Fig. 1
1. bronze medal U elbows, 2. weld seams, 3. copper pipe interfaces, 4. bronze medal aluminium composite welds, 5. aluminum pipes, 6. fins, 7. pipelines wherein.
The specific embodiment
The utility model is made up of the pipeline 7 of refrigerant and the fin 6 that interts on this pipeline 7 circulation, it is characterized in that above-mentioned pipeline 7 is made of with the copper aluminum compound structure pipeline body that welds mutually with it, copper pipe interface 3 is arranged copper U elbow 1 (being the U-shaped copper elbow), this copper aluminum compound structure pipeline body is that two ends have copper pipe interface 3, is connected with aluminum pipe 5 therebetween.The copper aluminum pipe of this copper aluminum compound structure pipeline body connects into copper aluminium composite weld 4.
The utility model is fixed on fin on the pipeline by the tube apparatus that rises in that the fin of interting is arranged on the copper aluminum compound structure pipeline body of copper pipe interface, and in the automatic brazing stove, copper pipe interface and copper U elbow 1 weld together and form the nest plate tube radiator.
As Fig. 1, the utility model is an aluminium in the middle of the existing full copper pipe pipeline of nest plate tube radiator is changed into, and pipe end has the copper aluminum compound structure pipeline body of copper pipe interface.In Fig. 2, can see, be welded with one section copper pipe 3 in the termination of aluminum pipe 5, and the composition surface of copper pipe 3 and aluminum pipe 5 is that copper pipe is at interior, aluminum pipe copper aluminium composite weld 4 outside, external diameter equates with the interior external diameter of aluminum pipe 5 in the pipeline of the welding point that this copper aluminium composite weld 4 constitutes, and Jia Gong copper aluminum composite pipes road can be satisfied and worn fin and the technological requirement of the pipe that rises like this.Carry out at copper-brazed seam 2 places copper U elbow 1 and copper aluminum compound structure pipeline body being welded together in the gas brazing subsequently.
For the ease of implementing and ensuring the quality of products, wherein copper aluminum compound structure pipeline body processing technology discloses as follows: at first copper pipe 1 weld part is processed into the very thin undergauge straight tube-like of tube wall, copper pipe that cover is connected and aluminum pipe are met sb. at the airport by Pressure Welding and are welded again, form the welding point of copper aluminum composite pipes road part, to the undergauge straight tube-like copper pipe enlarging of welding point inside, the joint internal diameter size is equated with the internal diameter of aluminum pipe then.Because the straight tube-like tube wall behind the copper pipe undergauge is very thin as previously mentioned, so the smooth smooth no step in pipeline copper aluminium joint portion after the processing can satisfy the requirement that pipeline is shaped, interts subsequent machining technologies such as fin, mechanical tensioner fin fully.
