Hole 12.Carried out in such manner, it is possible to make the refrigerant (or other media) in header 2 to enter by through hole 12 in micro channel 11
Exchange heat (or other work), or the refrigerant (or other media) in micro channel 11 is flowed into header 2 by through hole 12.
In actual fabrication, the quantity of through hole 12 can be twice of the quantity of micro channel 11, the correspondence of each two through hole 12
One micro channel 11, and it is separately positioned on the both ends of heat exchanger tube 1.That is, pass through respectively in each micro channel 11
The tube chamber for being arranged on the through hole 12 at the both ends of heat exchanger tube 1 and two headers 2 at the both ends of heat exchanger tube 1 connects, refrigerant (or other
Medium) in a tube chamber of header 2, it can be flowed into therefrom by the corresponding through hole 12 that obtains in micro channel 11, Ran Houtong
Another through hole 12 is crossed to flow into another tube chamber of header 2.
Second of optional mode, as shown in figure 5, location structure includes the location-plate 3 being arranged in header 2, location-plate 3
On be provided with threeth positioning hole 31 relative with the first positioning hole 21, heat exchanger tube 1 is through the 3rd positioning hole 31 and by further fixed
Position.Wherein, the first positioning hole 21 and the 3rd positioning hole 31 can be coaxially disposed, and axis intersects with the axis of header 2.
Location-plate 3 can use welding or other be fixedly connected with mode and be fixed on the inwall of header 2, can also pass through
Dismountable connected mode such as clamping is arranged on the inwall of header 2.Preferably, the end of heat exchanger tube 1 positions through first
The positioning hole 31 of hole 21 and the 3rd, is fixedly connected on connecting hole 23 and positioning hole 31；Wherein heat exchanger tube 1 is fixedly connected with the first positioning
Can be by the way of welding on the positioning hole 31 of hole 21 and the 3rd, but it is not limited to this.
As a kind of embodiment, as shown in figure 1, the quantity of heat exchanger tube 1 is at least two, and the row of being parallel to each other
Cloth.That is the both ends of at least two heat exchanger tube 1 can be connected on two headers 2.
To realize goal of the invention, the present invention also provides a kind of micro-channel heat exchanger, and it includes any of the above technical characteristic
Pipe connecting structure.
The present invention avoids header that downward shift occurs, and then ensure with that can strengthen pipe connecting structure stability
Flat tube and inner water tank are brought into close contact the accuracy being connected with header with the fastener on inner bag.Also there is structure simultaneously
Simply, the advantages that easily making.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
