Embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Coiled pipe micro-channel heat exchanger 100 according to embodiments of the present invention is described below with reference to Fig. 1-Figure 12.
Coiled pipe micro-channel heat exchanger 100 according to embodiments of the present invention, as shown in Figure 1, including：Two 1 Hes of header
Multiple flat tubes 2.
Each header 1 is equipped with multiple recirculation holes 13, and at least two recirculation holes 13 are in the circumferential on each header 1
Stagger setting.Two recirculation holes 13 stagger setting in the circumferential direction of header 1 mentioned herein, refers to two recirculation holes 13
Projection of the central axes on the cross section of header 1 is staggered (i.e. misaligned), it may also be said to, refer to two recirculation holes 13 in afflux
It is not axially spaced setting on pipe 1.
Multiple flat tubes 2 are connected in parallel between two headers 1, at least a portion of each flat tube 2 wriggle extension or
Extend around header 1, the both ends of each flat tube 2 are connected with the recirculation hole 13 on two headers 1 respectively, multiple flat tubes 2 and
Multiple recirculation holes 13 on each header 1, which correspond, to be set.
Specifically, single flat tube 2 is longer in coiled pipe micro-channel heat exchanger 100, therefore, every flat tube 2 be required to by
Repeatedly bending.Since flat tube 2 is longer, the bending shape of each flat tube 2 can be multimodal various, for example, often upper flat tube 2 can be such as Fig. 1 institutes
The sinuous extension shown, every flat tube 2 can repeatedly be bent into multiple straight pipes, and multiple straight pipes can form at least one tube layer,
Multiple straight pipes are parallel to each other in each tube layer.In another example as shown in figure 11, each flat tube 2 can surround one of header 1
Extension, every flat tube 2 can repeatedly bend to multiple arcs pipeline section, and multiple arcs pipeline section can form at least one tube layer, each
Multiple arcs pipeline section is arranged successively in tube layer.Certainly, since flat tube 2 is longer, flat tube 2 can also make prolonging for other shapes
Stretch, be not especially limited here.
More specifically, as shown in Figure 1, two headers 1 include inlet header 11 and outlet collection pipe 12, each afflux
Adapter 4 is connected with pipe 1, multiple parallel connection flat tubes 2 are connected between inlet header 11 and outlet collection pipe 12.Between flat tube 2
Arrange matched fin 3, some heat exchangers further include side plate 5, and side plate 5 is arranged on the outermost in same tube layer, side plate 5
Fin 3 is connected between outermost straight pipe or arc pipeline section.Refrigerant flows into multiple flat tubes 2 through inlet header 11,
Refrigerant exchanges heat in multiple flat tubes 2 in flow process with outside air, then flows out flat tube 2 and is flowed out in outlet collection pipe 12.
In coiled pipe micro-channel heat exchanger disclosed in the prior art, a flat tube is provided only with usual heat exchanger, causes to make
Cryogen path is long.If it is desired to set multiple flat tubes on heat exchangers, those skilled in the art also only can be according to common micro- logical
The Design Thinking of road heat exchanger, by axially spaced setting of multiple flat tubes along header, the intercommunicating pore central axes of multiple flat tubes
Coincide on header cross section.And each cross section short side of flat tube and the axis parallel of header, it is desirable to header
It is relatively large in diameter, if wanting two layers of tube layer, heat exchanger is overall thicker, and structure type is single, and inconvenience is installed on narrow sky
In.
Coiled pipe micro-channel heat exchanger 100 according to embodiments of the present invention, it is in parallel by setting more flat tubes 2 in parallel
More flow paths share same inlet header 11 and outlet collection pipe 12, the length of single refrigerant flow path can be shortened, to reach
Reduce the purpose of the resistance of heat exchanger refrigerant effluent and pressure drop.Using the refrigeration system of the heat exchanger when compressor horsepower is specified,
Since refrigerant side pressure drops reduce, the temperature difference of refrigerant and air side can be increased, improve heat exchange efficiency.In addition, it can also expand snake
The application scenario of shape pipe micro-channel heat exchanger 100.
According to an embodiment of the invention, as shown in Figure 1, the cross section (perpendicular to section of length direction) of flat tube is flat
Shape, the cross section of flat tube have long side and short side.Since each flat tube 2 will be through repeatedly bending or bending, flat tube is in bending place
If bending is reversed excessively, flat tube internal diameter can diminish, and be unfavorable for refrigerant circulation.Therefore in embodiments of the present invention, same to tube layer
Interior flat tube 2 is bent in bending around the long side of flat tube cross section.The central axes of multiple pipeline sections of flat tube 2 are positioned at same in same tube layer
In one plane.
Specifically, the axial direction general parallel orientation of the long side of each recirculation hole 13 and corresponding header 1, in this way, afflux
1 outside diameter of pipe is small, occupies little space, and the cost of material is low.In addition, when heat exchanger overall dimensions by limited time, this 1 occupied space of header
Few, the available effective heat exchange area of heat exchanger is big, for mainly undertake the flat tube 2 of heat exchange effect and fin 3 provides bigger can
Using space, therefore heat exchange amount is big.
In embodiments of the present invention, the width of flat tube 2, thickness and 3 type of fin and specific geometric parameter in each tube layer
It may be the same or different, the physical dimension for the recirculation hole 13 being connected on the tube wall of corresponding header 1 with each rows of flat pipes 2 can phase
Together also can be different.
In embodiments of the present invention, on same comb layer, the parameter such as the thickness of flat tube 2, tube spacing, 3 type of fin can be with
It is identical also can be different, the physical dimension for the recirculation hole 13 being connected on the tube wall of corresponding header 1 with each flat tube 2 in arranging
It may be the same or different.
In embodiments of the present invention, the structure type of multiple arrangements of flat tubes 2 has a variety of, for example, such as Fig. 1, Fig. 8, Fig. 9 and figure
In the central axes of more flat tubes 2 are generally aligned in the same plane shown in 11, in coiled pipe micro-channel heat exchanger 100, after more flat tubes 2 are bent
The multiple pipeline sections formed are located in same tube layer.Thus, it can be achieved that arranging more flat tubes 2 in a row, more flat tubes 2 form more
The heat exchanger structure of flow path parallel connection.
In another example header 1 can be cylindrical drum, polygon column casing, special shape tube etc., for header shape of cross section here
It is not specifically limited.In another example coiled pipe micro-channel heat exchanger may also set up multiple rows of tube layer, to strengthen exchanging heat, while header 1
Pipe tap position (recirculation hole 13) can interlaced arrangement.
Further for example, as shown in figure 12, coiled pipe micro-channel heat exchanger 100 can do inlet collecting 11 with a header 1
With outlet collection pipe 12,1 inner cavity of header is divided into two chambers by partition plate 6 during the middle part of header 1 is set at this time.
