Abstract
The utility model provides a combined-type collecting main of an automobile heat exchanger. The combined-type collecting main of the automobile heat exchanger is characterized by comprising a collecting main, wherein baffle plates are arranged at both left side and the right side of the collecting main for assembling; and a flat pipe insertion groove plate is welded to the front side of the collecting main. The device provided by the utility model can be used for overcoming the defects of the prior art, is simple in structure, is convenient to manufacture, and can be used for lowering the machining cost, and improving the welding quality.
Description
Technical field
The utility model relates to a kind of combined type collecting pipe of automotive heat exchanger, belongs to heat exchanger header technical field.
Background technology
At present, the header of automotive heat exchanger mainly contains two kinds of methods, a kind of is to adopt the pipe punch forming, usually adopt the hydraulic press punch forming, need to insert plug in pipe, complicated operation, efficient is low, can't determine the insertion depth of flat tube when assembling, or determine the flat tube insertion depth by plug; Another kind method is combined into header after by the Sheet Metal Forming Technology moulding of sheet material by complexity, and diel is complicated, and the initial investment cost is high.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of combined type collecting pipe of simple in structure, easily manufactured automotive heat exchanger.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of combined type collecting pipe of automotive heat exchanger, it is characterized in that: comprise header, the header left and right sides is equipped with the dividing plate assembling, and the flat tube slot board is welded in the header front side.
Preferably, described header is the dual-cavity shape, respectively is provided with 1 flat tube locating surface on the 4 parallel internal faces in place of header, also is provided with septalium on internal face.
Preferably, the upper, middle and lower of described flat tube slot board is provided with the parallel projection in 3 places, vertically is provided with the flat tube groove between adjacent protrusion.
The header body of the combined type collecting pipe of a kind of automotive heat exchanger that the utility model provides forms the shape of dual-cavity by drawing process, can save complicated diel, and the flat tube locating surface can conveniently be determined the insertion depth of flat tube when assembling.3 place's convex inner walls of flat tube slot board can increase the welding contact area with header, improve welding quality, and the outer wall of projection can play guide effect when assembling, be conducive to the assembling of flat tube.
The device that the utility model provides has overcome the deficiencies in the prior art, and is simple in structure, easily manufactured, reduced processing cost, and improved welding quality.

The specific embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The combined type collecting pipe schematic diagram of a kind of automotive heat exchanger that Fig. 1 provides for the utility model, the combined type collecting pipe of described a kind of automotive heat exchanger is formed by header 1, flat tube slot board 2 and dividing plate assembling 3.Dividing plate assembling 3 all is equipped with in header 1 left and right sides, and flat tube slot board 2 is contained in header 1 front side.
In conjunction with Fig. 2, header 1 body forms the shape of dual-cavity by drawing process, and 1 flat tube locating surface 1-1 is respectively arranged on the 4 parallel internal faces in place, uses straightforward procedure to process septalium 1-2 and side change hole.Header 1 uses drawing process, can save complicated diel, and the flat tube locating surface can conveniently be determined the insertion depth of flat tube when assembling.
In conjunction with Fig. 3 and Fig. 4, flat tube slot board 2 is simple in structure, by double-sided composite plate, by Sheet Metal Forming Technology, at an upper portion thereof, the 3 projection 2-1 of places are formed at middle part and bottom, use the method that punctures moulding to process vertical flat tube groove 2-2 between adjacent protrusion 2-1.In conjunction with Fig. 5, during use, flat tube 4 inserts in flat tube groove 2-2.3 place's convex inner walls of flat tube slot board 2 can increase the welding contact area with header 1, improve welding quality, and the outer wall of projection can play guide effect when assembling, be conducive to the assembling of flat tube 4.
The combined type collecting pipe of a kind of automotive heat exchanger that the utility model provides can be used for the parallel-flow evaporator of air conditioning for automobiles, forms main refrigerant channel, has reduced manufacturing cost, has improved product quality and performances.
