Abstract
An aluminum brazed air conditioner evaporator comprises cooling fins and refrigerant circulation pipelines, wherein the refrigerant circulation pipelines are brazed in the cooling fins, and the cooling fins and the refrigerant circulation pipelines are all made of aluminum. After the aluminum brazed air conditioner evaporator is brazed by adoption of total aluminum material, product strength is substantially improved, and service life of a product is prolonged; after the brazing, the cooling fins and the refrigerant circulation pipelines can be in close contact with one another, and compared with that of an existing technological product, the heat conductivity coefficient is increased by 35-60%; after the total aluminum structure is adopted, the cost is reduced by 30% compared with an existing copper-aluminum mixed structure product; and technological processes are reduced, an expansion pipe flaring link in the traditional technology is saved, and the problems that in the traditional technology, the percentage of contraction of an expansion pipe is not even, the expansion pipe is not tight and the flaring is fractured are avoided.
Description
Technical field
The utility model relates to an A/C evaporator, and what be specifically related to is a kind of aluminum braze welding type A/C evaporator.
Background technology
The copper aluminium mixed structure that present A/C evaporator generally adopts, be that the pipe for flowing of refrigerant road is a copper pipe, and the outer fin of copper pipe is an aluminium, the process that is adopted is after fin is inserted in copper pipe, make copper pipe expansion (pipe rises) by external force, thereby fully contact with fin.
Because copper material intensity is not high, when having the good processing properties advantage, also has potential hidden danger of quality, as the process of the pipe that rises a scuffing copper pipe that very easily occurs rising, forming perforating wound causes copper pipe to reveal, sometimes because the burr of aluminium foil endoporus is excessive, burr stings copper pipe and causes leakage in the pipe that rises, and does not carry out any welding after making copper pipe and aluminium radiator fin contacts by tension force, thereby has reduced the intensity of product; Because contact between the two is not tight, can the heat-conductive characteristic of product be made a big impact simultaneously, except that this above-mentioned shortcoming, the evaporimeter that adopts copper aluminium to mix, the copper consumption still accounts for 80% of evaporator tube material use quantity, and cost is higher.
The utility model content
In order to overcome the deficiency that above-mentioned technology exists, technical problem to be solved in the utility model provides a kind of product strength height, good heat conductivity, aluminum braze welding type A/C evaporator that cost is low, overcome not tight, the enlarging problems of crack of expand tube shrinkage factor inequality, expand tube that exists in the traditional handicraft, improve efficient, reduced fault rate.
The technical solution of the utility model is: aluminum braze welding type A/C evaporator, comprise fin, pipe for flowing of refrigerant road, it is characterized in that: described fin is with many pipe for flowing of refrigerant roads and by adding auxiliary agent with fin and the soldering of pipe for flowing of refrigerant road together, described fin, pipe for flowing of refrigerant road all adopt aluminium to make.
Advantage of the present utility model: 1, adopt full aluminium material and carry out soldering after, product strength has had significantly and has improved, and has increased the service life of product; 2, carry out soldering after, both can closely contact, and compare with existing handicraft product, thermal conductivity factor increases 35%-60%; 3, behind the employing all-aluminium construction, reduce by 30% than existing copper aluminium mixed structure product cost; 4, technological process reduces, and has saved the pipe enlarging link that rises in the traditional handicraft, has avoided not tight, the enlarging problems of crack of expand tube shrinkage factor inequality, expand tube that exists in the traditional handicraft.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings, technology contents of the present utility model is described further:
As shown in Figure 1, aluminum braze welding type A/C evaporator, comprise fin 1, pipe for flowing of refrigerant road 2, be with many pipe for flowing of refrigerant roads 2 on the fin 1 and by adding auxiliary agent with fin 1 and 2 solderings of pipe for flowing of refrigerant road together, described fin 1, pipe for flowing of refrigerant road 2 all adopt aluminium to make.After soldering, fin 1 can closely contact with pipe for flowing of refrigerant road 2, compares with existing handicraft product, and thermal conductivity factor increases 35%-60%; After adopting full aluminium material and carrying out soldering, product strength has had significantly raising, has increased the service life of product.
