Referring to fig. 1 to 10, the present invention provides a structure of a refrigerant distribution device 100, including an inner distribution pipe 10 and an outer distribution pipe 20, wherein the outer distribution pipe 20 is sleeved outside the inner distribution pipe 10; it is noted that the inner distribution pipe 10 is provided with a plurality of kinds of the hole units 11, and each of the hole units 11 includes a plurality of inner distribution holes 111; the outer distribution pipe 20 is provided with an outer distribution hole 21; the relative positions of the inner distribution pipe 10 and the outer distribution pipe 20 are adjusted so that the inner distribution holes 111 and the outer distribution holes 21 of at least one of the hole units 11 correspond to each other, and the refrigerant is discharged from the inner distribution holes 111 and the outer distribution holes 21 in this order.
The refrigerant distribution device 100 provided by the utility model has the advantages that: the inner distribution pipe 10 is provided with the plurality of hole units 11, so that the inner distribution pipe is suitable for requirements of various distribution flows and has a wide application range; the relative positions of the inner distribution pipe 10 and the outer distribution pipe 20 are adjusted and changed, so that the inner distribution holes 111 of required types can be adjusted to correspond to the outer distribution holes 21, the required inner distribution holes 111 are flexibly selected, the inner distribution pipe 10 does not need to be replaced, and the working efficiency is improved; in addition, the refrigerant distribution device 100 provided by the application completes the adjustment and selection of the types of the hole units 11 on the basis of not additionally arranging other structures, has a simple structure and reduces the cost.
It is noted that, referring to FIGS. 3, 4, 8 and 9, each cell unit 11 includes a plurality of inner dispensing apertures 111, e.g., each cell unit 11 of FIGS. 3 and 4 includes inner dispensing aperture a1 and inner dispensing aperture a 2; for example, the hole unit a in fig. 8 and 9 includes the inner distribution hole a1, the inner distribution hole a2, the inner distribution hole a3, and the like, and the number of the inner distribution holes 111 in each hole unit 11 is not limited.
Referring to fig. 3 and 4, or to fig. 8 and 9, in one embodiment, the plurality of inner distribution holes 111 in each of the hole units 11 are arranged along the axial direction of the inner distribution pipe 10 so that the inner distribution holes 111 correspond to the outer distribution holes 21 when the relative positions of the inner distribution pipe 10 and the outer distribution pipe 20 are adjusted, so that the inner distribution pipe 10 communicates with the interior of the header 200 through the inner distribution holes 111 and the outer distribution holes 21, so that the refrigerant in the inner distribution pipe 10 is sequentially distributed from the inner distribution holes 111 and the outer distribution holes 21 into the header 200. Of course, in other embodiments, the arrangement of the plurality of inner distribution holes 111 in each of the hole units 11 is not limited to the above or shown in the drawings.
Further, referring to fig. 3, the plurality of inner distribution holes 111 in each hole unit 11 have the same diameter, and the plurality of inner distribution holes 111 are distributed in the inner distribution pipe 10, and the same diameter of the inner distribution holes 111 can ensure uniform distribution of the refrigerant at each location of the inner distribution pipe 10. In addition, when the required refrigerant flow is estimated, the bore diameter of the inner distribution holes 111 is the same, so that the refrigerant distribution amount can be calculated, and the relative position between the inner distribution pipe 10 and the outer distribution pipe 20 is adjusted according to the bore diameter, so that the adjustment efficiency is improved. In other embodiments, the diameters of the plurality of inner distribution holes 111 in each hole unit 11 may be different, so that the flow rate of the refrigerant distributed from various places on the inner distribution pipe 10 is different, so as to enhance the turbulence degree of the refrigerant in the header 200.
Referring to fig. 3, the plurality of inner distribution holes 111 in each cell unit 11 are equally spaced to allow the inner distribution holes 111 to be regularly arranged, thereby facilitating the arrangement of the inner distribution holes 111 in the plurality of cell units 11. Of course, in other embodiments, the spacing between the plurality of inner distribution holes 111 in each of the hole units 11 may not be equal.
Referring to fig. 1 to 4, a plurality of kinds of orifice units 11 are arranged along an axial direction of an inner distribution pipe 10; the length of the inner distribution pipe 10 extending into the outer distribution pipe 20 is adjusted so that the inner distribution hole 111 in the at least one kind of hole unit 11 corresponds to the outer distribution hole 21. For example, referring to fig. 4, the inner distribution pipe 10 of fig. 4 is provided with a plurality of hole units 11, which are respectively numbered A, B. Before the adjustment, the inner distribution hole 111 of the hole unit a corresponds to the outer distribution hole 21, the inner distribution pipe 10 is moved such that the inner distribution hole 111 of the hole unit B corresponds to the outer distribution hole 21, the inner distribution hole 111 of the hole unit a is blocked by the inner wall of the outer distribution pipe 20, and the refrigerant in the inner distribution pipe 10 is in a high-pressure state, so that the high-pressure refrigerant cannot flow out from the blocked inner distribution hole 111 of the hole unit a, but flows out only from the inner distribution hole 111 of the hole unit B corresponding to the outer distribution hole 21, thereby realizing the replacement of the hole unit 11. Of course, the arrangement scheme of the plurality of hole units 11 is not limited to the above, for example, in the embodiments shown in fig. 6 to 9, the plurality of hole units 11 may be arranged along the circumferential direction of the inner distribution pipe 10, for example, the hole unit a, the hole unit B, the hole unit C, and the hole unit D may be arranged along the circumferential direction of the inner distribution pipe 10, or other arrangement schemes may be adopted.
With particular reference to the embodiment shown in fig. 6-9, the various orifice units 11 are arranged along the circumference of the inner distribution pipe 10; thereby adjusting the angle of the inner distribution pipe 10 in the circumferential direction such that the inner distribution holes 111 in the at least one hole unit 11 correspond to the outer distribution holes 21, thereby adjusting the flow rate of the refrigerant flowing out of the inner distribution pipe 10. Of course, in other embodiments, the arrangement scheme of the plurality of hole units 11 is not limited to the embodiments shown in fig. 1 to 4 and fig. 6 to 9, and other arrangement schemes are also possible.

Referring specifically to fig. 3 and 4, in the cell a, the distance between the adjacent inner distribution holes a1 and a2 is La1The distance between the inner distribution hole a2 and the inner distribution hole a3 is La2(not shown in the drawings), the distance between the adjacent inner distribution holes B1 and B2 is L in the hole unit Bb1The distance between the inner distribution hole b2 and the inner distribution hole b3 is Lb2(not shown), the spacing between the hole units A and B is equal, which means that L is located at a corresponding positiona1And Lb1Equal, La2And Lb2Are equal. Alternatively, for example, in the embodiment shown in FIGS. 8 and 9, a plurality of kinds of the hole units 11 are circumferentially arranged along the inner distribution pipe 10, and a plurality of inner distribution holes 111 in each of the hole units 11 are distributed along the inner distributionIn the axial distribution of the pipe 10, the equal spacing between the plurality of kinds of hole units 11 means that the corresponding inner distribution holes a1 and inner distribution holes b1 have equal spacing therebetween, and it can also be understood that, in the present embodiment, the plurality of kinds of hole units 11 are uniformly arranged along the circumferential direction of the inner distribution pipe 10, so that the spacing between the plurality of hole units 11 is equal. Of course, in other embodiments, there are multiple layout schemes for the arrangement and the spacing between the multiple hole units 11, and the spacing between the multiple hole units 11 may also be unequal, and is not limited to the layout scheme described above.

Of course, in other embodiments, the arrangement of the outer dispensing orifice 21 is not limited to the above, and may be suitably modified depending on the arrangement of the inner dispensing orifice 111.
