The utility model content
Technical problem to be solved in the utility model is to solve a large amount of copper pipe, cost problem of higher used in the air-conditioning product.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of copper aluminium composite tubing, be used for air-conditioning condenser or evaporimeter, comprise copper internal layer and aluminum skin, described copper aluminium composite tubing at described copper internal layer and the outer faying face of described aluminum place, mutually diffuses to form binder course by described copper internal layer and described aluminum skin through hot rolling, cold-drawn.
The utility model also provides a kind of air-conditioning condenser, blast pipe in the described air-conditioning condenser, muffler, throttle capillary tube, condenser elbow and condenser U-shaped heat exchanger tube are for comprising the outer field copper aluminium composite tubing of copper internal layer and aluminum, described copper aluminium composite tubing at described copper internal layer and the outer faying face of described aluminum place, mutually diffuses to form binder course by described copper internal layer and described aluminum skin through hot rolling, cold-drawn.
The utility model also provides a kind of A/C evaporator, feed tube, escape pipe, elbow and U-shaped heat exchanger tube in the empty evaporimeter of described air-conditioning are and comprise copper internal layer and the outer field copper aluminium composite tubing of aluminum, described copper aluminium composite tubing at described copper internal layer and the outer faying face of described aluminum place, mutually diffuses to form binder course by described copper internal layer and described aluminum skin through hot rolling, cold-drawn.
The utility model also provides a kind of air-conditioning, comprise condenser, evaporimeter and the indoor and outdoor connecting pipe that is communicated with described condenser and evaporimeter, blast pipe in described indoor and outdoor connecting pipe and the described condenser, muffler, throttle capillary tube, feed tube in condenser elbow and condenser U-shaped heat exchanger tube and the described evaporimeter, escape pipe, elbow, the U-shaped heat exchanger tube is and comprises copper internal layer and the outer field copper aluminium composite tubing of aluminum, described copper aluminium composite tubing is through hot rolling, cold-drawn diffuses to form binder course at described copper internal layer and the outer faying face of described aluminum place mutually by described copper internal layer and described aluminum skin.
The utility model, because at described copper internal layer and the outer faying face of described aluminum place, be provided with by described copper internal layer and described aluminum skin and diffuse to form binder course mutually, between the copper aluminium structure composition of metallurgical binding the advantage of copper aluminium aspect heat exchange, utilize the moment heat absorption capacity of copper excellence that the heat in the cold-producing medium is taken in the copper layer, the copper aluminium lamination that passes through combination between atom does not have thermal resistance to exist in the outer field aluminium of heat transferred in the transmittance process again.The condenser of this novel tube manufacturing, evaporimeter are compared low cost of manufacture, good effect of heat exchange, in light weight with pure copper tube.
Description of drawings
Fig. 1 is the structural representation of the utility model copper aluminium composite tubing;
Fig. 2 is the air conditioner structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises copper internal layer 102 and aluminum skin 100, at the outer 100 faying face places of described copper internal layer 102 and described aluminum, diffuses to form binder course 101 mutually by described copper internal layer and described aluminum skin.The formation of described binder course 101 is based on plastic working, pressure welding and thermomechanical treatment principle, promptly respectively the faying face of copper pipe internal layer 102 and aluminum pipe skin 100 being made surface finish handles and suit, the composite pipe blank of the outer aluminium of copper in perhaps producing by the composite continuous casting method, and then utilize the planetary rolling machine that the copper aluminum composite pipes base is carried out single pass, high deformation velocity, aximal deformation value rolling, make the very big distortion heat of pipe deformed area moment generation that is rolled, cause being rolled the copper of composite pipe and alloy thereof and aluminium and alloy thereof crystallization again takes place dynamically to recover at the faying face place, to realize copper aluminium faying face metallurgical binding.A kind of concrete grammar is that to utilize the planetary rolling machine be 50%～95% to the copper aluminum composite pipes base in the single pass contraction percentage of area, and the outlet mill speed is 5m/min～30m/min, and the deformed area temperature is raised under 200～600 ℃ the situation carries out one-pass roller.Copper aluminium composite tubing after rolling is quickly cooled to room temperature, can without annealing situation under directly drawing, be met the copper aluminium composite tubing of requirement or obtain the compound internal thread tubing of copper aluminium through high speed spinning again.
As shown in Figure 2, Fig. 2 is the air conditioner structure schematic diagram, comprise condenser 20, evaporimeter 30 and the indoor and outdoor connecting pipe 5 that is communicated with described condenser 20 and evaporimeter 30, blast pipe 1 in described indoor and outdoor connecting pipe 5 and the described condenser 20, muffler 2, throttle capillary tube 3, feed tube 6 in condenser elbow 4 and condenser U-shaped heat exchanger tube 10 and the described evaporimeter, escape pipe 7, elbow 8 and U-shaped heat exchanger tube 9 are and comprise copper internal layer and the outer field copper aluminium composite tubing of aluminum, described copper aluminium composite tubing is through hot rolling, cold-drawn diffuses to form binder course at described copper internal layer and the outer faying face of described aluminum place mutually by described copper internal layer and described aluminum skin.
