Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, pipe connecting structure of the present utility model and micro-channel heat exchanger are further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of pipe connecting structure, including heat exchanger tube 1 and the header 2 being connected to heat exchanger tube 1 two ends.Heat exchanger tube 1 and header 2 can be aluminum, or other metal materials.Header 2 one sidewall is provided with accommodate heat exchanger tube 1 pass and be its carry out positioning first position hole 21, the position being positioned at heat exchanger tube 1 end on header 2 is additionally provided with the location structure for carrying out positioning by heat exchanger tube 1 end.Heat exchanger tube 1 is positioned on header 2 by the first hole 21, location and location structure.Wherein heat exchanger tube 1 can be flat tube.
By using said structure, heat exchanger tube 1 can be positioned on header 2 at two positions at the first hole 21, location and at location structure, heat exchanger tube 1 is time connecting portion deflects at one wherein, at another, connecting portion can be exchanged heat pipe 1 and carries out spacing, improve the stability of structure, avoiding during assembling, because being there is downward shift by external force in header 2.
Hereinafter two kinds of optional modes of location structure are described in detail
The first optional mode, location structure is the second hole 22, location being arranged on header 2 sidewall as shown in Figure 2, and the end of heat exchanger tube 1 is positioned through the second hole 22, location.Wherein, the first hole 21, location and the second hole 22, location can be coaxially disposed, and the axes intersect of axis and header 2.Preferably, the end of heat exchanger tube 1 through the first hole, location 21 and the second hole, hole 22, location, and can be fixed on hole, connection the first location 21 and the second hole, hole 22, location.Wherein heat exchanger tube 1 fixing connection in the way of using welding, but can be not limited to this on the first hole, location 21 and the second hole, hole 22, location.
As shown in Figure 2,4, the end of heat exchanger tube 1 can be towards the tapered structure of free end, such as taper.So can be easy to from the first hole, location 21 and the second hole, hole 22, location, pass the end of heat exchanger tube 1, at this moment the port of heat exchanger tube 1 leans out outside header 2, it need to be blocked, prevent the coolant in heat exchanger tube 1 (or other media) from revealing herein.In real work, can by the end of heat exchanger tube 1 is pounded flat by the way of the end of heat exchanger tube 1 is made as taper, the port of such heat exchanger tube 1 can diminish, be conducive to it is blocked.
More preferably, as shown in Figure 3,4, the micro channel 11 of the internal at least two also including connecting with the tube chamber of header 2 of heat exchanger tube 1, it is positioned on the intraluminal heat exchanger tube 1 of header 2 and is additionally provided with the through hole 12 connected with header 2 by micro channel 11.So, the coolant in header 2 (or other media) can be made can be entered by through hole 12 micro channel 11 carries out heat exchange (or other work), or the coolant (or other media) in micro channel 11 is flowed in header 2 by through hole 12.
In actual fabrication, the quantity of through hole 12 can be the twice of micro channel 11 quantity, the corresponding micro channel 11 of each two through hole 12, and is separately positioned on the two ends of heat exchanger tube 1.That is, connected by the tube chamber of two headers 2 at the two ends of the through hole 12 with heat exchanger tube 1 that are arranged on the two ends of heat exchanger tube 1 respectively at each micro channel 11, coolant (or other media) can be from which in header 2 tube chamber, by corresponding that through hole 12 flows in micro channel 11, then flowed in another header 2 tube chamber by another through hole 12.
The optional mode of the second, as it is shown in figure 5, location structure includes the location-plate 3 being arranged in header 2, location-plate 3 is provided with the threeth location hole 31 relative with the first hole 21, location, and heat exchanger tube 1 is further positioned through the 3rd hole 31, location.Wherein, the first hole 21, location and the 3rd hole 31, location can be coaxially disposed, and the axes intersect of axis and header 2.
Location-plate 3 can use welding or other fixing connected modes to be fixed on the inwall of header 2, it is also possible to is arranged on the inwall of header 2 by dismountable connected modes such as clampings.Preferably, the end of heat exchanger tube 1, through the first hole, location 21 and the 3rd hole 31, location, is fixedly connected on connecting hole 23 and hole 31, location；Wherein heat exchanger tube 1 fixing connection in the way of using welding, but can be not limited to this on the first hole, location 21 and the 3rd hole 31, location.
As a kind of embodiment, as it is shown in figure 1, the quantity of heat exchanger tube 1 is at least two, and it is arranged mutually parallel.That is the two ends of the heat exchanger tube 1 of at least two all can be connected on two headers 2.
For realizing goal of the invention, this utility model also provides for a kind of micro-channel heat exchanger, and it includes the pipe connecting structure of any of the above technical characteristic.
This utility model has can reinforced pipe pipeline connecting structure stability, it is to avoid header generation downward shift, and then ensure that fitting tightly and accuracy that header is connected of flat tube and inner water tank with the securing member on inner bag.The most also there is the advantages such as simple in construction, easy making.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
