As shown in Figure 4, the several individual components 11,12,13 forming header 1 contact with each other, and the part contacted, comprises two other parts 12,13 by parts 11.
As shown in Figure 4, the end of the heat exchanger tube 2 of such as flat tube adopts reducing structure, and this end is inserted in the opening of header, and utilize reducing to locate relative to header 1, as shown in Figure 4, the heat exchanger tube 2 of such as flat tube can be avoided to contact with the 3rd parts 13 of header 1, thus cause weldering stifled.
Embodiment 4
On the basis of embodiment 1, further improvement has been carried out according to embodiments of the invention 4.Specifically, as shown in Figure 5, header 1 does not have the refrigerant tubing 115 shown in Fig. 2, and cold-producing medium enters cavity 18 and limited by the first curved wall portion 111 and partition wall portions 114.
Embodiment shown in Fig. 2 with 3 reduces cold-producing medium further when being to ensure that other parts, technique are identical relative to the advantage of the embodiment shown in Figure 4 and 5 and enters cavity 18, thus refrigerant can be improved enter the problem that the two-phase refrigerant after header 1 is separated, improve the distribution of refrigerant, improve the heat exchange property of heat exchanger.
In the above-described embodiments, header 1 is used as inlet header, and obvious header 1 also can be used as outlet collection pipe.
It can be seen from the above, the invention provides a kind of header and a kind of heat exchanger, by multiple independent parts are connected, and the problem that the two phase flow improving the heat exchanger of such as micro-channel heat exchanger distributes, and improve heat exchange property.In addition, due to simple assembly technology, the present invention can improve the problem of unstable product quality.Moreover the present invention solves the high problem of current ratio-frequency welded tube cost.
Although in above-described embodiment, be described with circular header, above-described embodiment is equally applicable to the header of other cross sectional shapes, such as oval header, rectangle header etc.When header is the shape of any appropriate, the first arcuate wall in above-described embodiment is divided into the first U-shaped wall portion, and the second arcuate wall is divided into the second wall portion.The arcuate wall of second component is divided into the inverted U-shaped wall portion of second component.
