Abstract
The utility model relates to a collecting pipe for a vehicle air-conditioning evaporator and a condenser. The collecting pipe is formed through drawing an aluminum alloy pipe, and the wall thicknesses of the cross section of the pipe are different in various directions. The utility model has the advantages of simple manufacturing technique, low cost and low leaking risk of products.
Description
Technical field
The utility model relates to refrigeration plant, relates in particular to evaporimeter and the used header of condenser in air conditioning for automobiles, refrigerator and the generating equipment.
Background technology
At present, the header that evaporimeter in air conditioning for automobiles, refrigerator and generating equipment and condenser are used generally uses double-layer aluminium alloy multiple tube (outer 4343/ internal layer, 3003 aluminium alloys).The double-layer aluminium alloy multiple tube mainly forms through the high frequency seam with clad aluminum foil, and the bad and leakage weldering of seam more easily takes place during because of seam, causes multiple tube to have bigger leakage quality risk; In addition, owing to produce raw material---the complex manufacturing of clad aluminum foil of multiple tube, the manufacturing cost height, the double-layer aluminium alloy multiple tube price that causes postorder to be produced is also more expensive.
Summary of the invention
The utility model exists risk of leakage and the high problem of cost at existing header, the header that provide a kind of and do not leak, cost is low.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Header, it draws moulding by tube and pipe of aluminium alloy, and its cross section does not wait in all directions wall thickness.
Further, the shape left-right symmetry of described cross section, the inner surface of this cross section is oval, its outer surface is formed by connecting by last horizontal line, last skew lines, side straight line and following horizontal line.
On described horizontal line, on skew lines, side straight line and down horizontal line transition be set respectively between any two connect circular arc.
Technique effect of the present utility model is:
Because the utility model adopts tube and pipe of aluminium alloy to draw moulding, thereby substitutes two-layer compound aluminium foil high frequency seam technology of the prior art, processing technology is simple; The raw material that use are tube and pipe of aluminium alloy, and cost is low; Header of the present utility model is a seamless aluminium tubing, and the product leakage risk also greatly reduces; Shape of product scolder when soldering is easy to fill, and does not need to adopt composite, and product cost is greatly reduced.
Description of drawings
Fig. 1 is for using the structural representation of evaporimeter of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Fig. 1 is an automobile air-conditioning evaporator, and described evaporimeter is made up of two headers 1 up and down and the many flat tubes 4 that connect two headers 1, is provided with undulatory aluminium foil 3 between adjacent two flat tubes 4, and the two ends of header 1 are provided with plug 2.
See Fig. 2, header 1 draws moulding by tube and pipe of aluminium alloy, and its cross section does not wait in all directions wall thickness.The shape left-right symmetry of described cross section, the inner surface of this cross section are oval, and its outer surface is formed by connecting by last horizontal line 11, last skew lines 13, side straight line 15 and following horizontal line 17.Last horizontal line 11, on skew lines 13, side straight line 15 and down horizontal line 17 transition be set respectively between any two connect circular arc 12,14,16.Shape of cross section of the present utility model is beneficial to scolder and fills, and need not use special composite, and the cost of material is low, make final products on the price relatively the about cost of clad aluminum tube coupling between 20%～30%.
Claims (3)
1. header is characterized in that it draws moulding by tube and pipe of aluminium alloy, and the wall thickness of its cross section on all directions do not wait.
2. according to the described header of claim 1, it is characterized in that the shape left-right symmetry of described cross section, the inner surface of this cross section is oval, and its outer surface is formed by connecting by last horizontal line, last skew lines, side straight line and following horizontal line.
