Abstract
The utility model relates to a copper-aluminium composited air-conditioning tube which comprises a copper tube body A, an aluminium tube and a copper tube body B, wherein the aluminium tube is arranged between the copper tube body A and the copper tube body B, and the copper tube body A, the aluminium tube and the copper tube body B are fixedly and hermetically connected into a whole. Because an air-conditioning refrigerant tube is modified from a pure copper tube into a composited tube prepared through the butt joint of the copper tubes and the aluminium tube, the two ends of the air-conditioning tube are provided with the copper tubes, and the middle of the air-conditioning tube is provided with the aluminium tube, so that the copper-aluminium composited air-conditioning tube has good plasticity and heat-conducting properties, the aluminium tube in the middle of the air-conditioning tube can be bent for deformation, and the copper tubes at the two ends of the air-conditioning tube can be subjected to expansion on connecting conical surfaces, thereby ensuring the sealing performance of tube connection. Compared with the existing pure copper tube, the copper-aluminium composited air-conditioning tube provided by the utility model has the using property of the copper tube, but the cost of a tube body with a unit length is just 1/9 of that of the copper tube, therefore, the economic benefit is remarkable.
Description
Technical field
The utility model relates to the car air conditioner component, relates in particular to the refrigerant tubing of car air conditioner.
Background technique
In automotive air-conditioning system, must use copper tube, existing good plasticity of copper tube and heat-conducting property have good weldability again; Therefore the refrigeration agent in the air-conditioning all is to transmit through copper tube, in the installation of air conditioners process, must be connected with copper tube between main frame and the blower fan; To realize heat exchange; In installation process, the two ends endoporus of copper tube must expand the connection conical surface, guarantees the sealability that pipeline connects.Because copper is world's metal in short supply; Along with the rising of global temperatures, the use amount of air-conditioning increases year by year, has further spurred the demand of copper tube; Cause improving constantly of market copper tube price; How under the prerequisite that does not influence usability, further reduce the air-conditioning manufacture cost, reducing air-conditioning is that people thirst for the technical problem that solves for a long time to the dependence of copper tube.
The model utility content
The purpose of the utility model provides a kind of copper aluminium combined air conditioner pipe.
The technological scheme that the utility model is taked is:
A kind of copper aluminium combined air conditioner pipe is characterized in that: comprise red copper body A, aluminium matter pipe and red copper body B, aluminium matter pipe is between red copper body A and red copper body B, and fixed seal connection is integral between the three.
Further, the fixed seal connection structure between aluminium matter pipe and red copper body A or the red copper body B is the over-surplus fit structure of hole axle.
Further, the fixed seal connection structure between aluminium matter pipe and red copper body A or the red copper body B is a fixedly welded structure of end face.
Further, the fixed seal connection structure between aluminium matter pipe and red copper body A or the red copper body B is the interference occlusion structure of hole axle.
Because the air-conditioning refrigerant pipe is made into by copper tube, the composite pipe of aluminium matter pipe to being connected into by simple copper tube; At the two ends of air-conditioning pipe is copper tube; The centre is an aluminium matter pipe, and this copper aluminium combined air conditioner pipe had both had good plasticity and heat-conducting property, and middle aluminium matter pipe can carry out bending deflection; The copper tube at two ends can connect the expansion of the conical surface, guarantees the sealability that pipeline connects.Compare with existing pure copper tube, the utility model possesses the usability of copper tube, but the cost of unit length body has only 1/9 of copper tube, and economic benefit very significantly.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the another kind of structural representation of the utility model;
Among the figure: 1-red copper body A; 2-aluminium matter pipe; 3-red copper body B.
Embodiment
Embodiment below in conjunction with description of drawings the utility model:
A kind of copper aluminium combined air conditioner pipe; As shown in Figure 1; It is made up of red copper body A1, aluminium matter pipe 2 and red copper body B3; Aluminium matter pipe 2 is between red copper body A1 and red copper body B3, and the fixed seal connection structure between aluminium matter pipe 2 and red copper body A1 or the red copper body B3 is the over-surplus fit structure of hole axle.
In this example, be fixedly connected through the end face welding manner between aluminium matter pipe and the red copper body and be integral.
Also can adopt the interference occlusion structure of hole axle to link into an integrated entity between aluminium matter pipe 2 and the red copper body.
