This embodiment illustrates that the diameters of the front holes 52 or the side holes 53 and 54 and the insertion lengths L of the plurality of branchedpipes 50 are all provided to be different from each other, but is not limited thereto. That is, at least ones of the diameters of the front holes 52 or the side holes 53 and 54 and the insertion lengths L of the reducedflow path parts 51 of the at least twobranched pipes 50 among the plurality of branchedpipes 50 may be provided to be different from each other. - As such, the first embodiment exemplifies that the inner diameters D and the insertion lengths L of the plurality of branched
pipes 50 are different from each other. Accordingly, refrigerant flow distribution may be adjusted, thereby increasing heat exchange capability. - Hereinafter, a specific example in which the inner diameters D of the reduced
flow path parts 51 of the plurality of branchedpipes 50 and the insertion lengths L of the branchedpipes 50 are provided to be different from each other will be described.FIG. 4 illustrates relations for each of the branchedpipes 50 in the heat exchanger between wind velocity at the height of a refrigerant pipe connected to the branchedpipe 50 and a refrigerant rate suitable to flow into the branchedpipe 50. Referring toFIG. 4 , it may be seen that in the heat exchanger, at a higher height, wind velocity increases, and so more refrigerant flow may be desirable. For more refrigerant flow, the inner diameter D of the reducedflow path part 51 may be increased and the insertion length L of the branchedpipe 50 may be reduced. -
FIG. 4 illustrates as an example that forty-two of the branchedpipes 50 are connected to theouter pipe 10, so that the refrigerant flows into a total of forty-two of the branchedpipes 50 according to an embodiment of the disclosure. - In this case, for forty-two of the branched
pipes 50, ones connected to refrigerant pipes at high heights of the heat exchanger may have the reducedflow path part 51 with the large inner diameter D and have the short insertion length L. - That is, it is appropriate to supply a large amount of refrigerant because the heat exchange capacity increases in a region where wind velocity is high, and it is appropriate to supply a small amount of refrigerant because the heat exchange capacity decreases in a region where wind velocity is low. To this end, in this embodiment, the inner diameters D of the reduced
flow path parts 51 and the insertion lengths L of the branchedpipes 50 are provided to be different depending on the wind velocity distribution, so that the possibility of adjusting the fluid flow distribution to the plurality of branchedpipes 50 may increase. - In this example, because the refrigerant pipes to which the branched
pipes 50 are connected are arranged in the height direction of the heat exchanger, the inner diameters D of the reducedflow path parts 51 and the insertion lengths L of the branchedpipes 50 are provided to be different from each other depending on the location in the height direction of the heat exchanger, but is not limited thereto. - As for the inner diameter D of the reduced
flow path part 51, the aforementioned structure may be regarded as an example of a structure in which the inner diameter of the reduced flow path part of one of at least two branched pipes, through which a fluid distributed to a fast air flow portion of the heat exchanger passes, is greater than the inner diameter of the reduced flow path part of the other branched pipe, through which a fluid distributed to a slow air flow portion of the heat exchanger passes. - Also, as for the insertion length L of the branched
pipe 50, the aforementioned structure may be regarded as an example of a structure in which the insertion length of one of at least two branched pipes into one outer pipe, through which the fluid distributed to a fast air flow portion of the heat exchanger passes, is shorter than the insertion length of the other branched pipe into the one outer pipe, through which the fluid distributed to a slow air flow portion of the heat exchanger passes. -

As illustrated inFIG. 13 , thefirst distributor 8 a includes anouter pipe 10 a having a cylindrical shape, a plurality ofconnection pipes 40 a provided on theouter pipe 10 a, and a plurality of branchedpipes 50 a joined to theouter pipe 10 a by being inserted into the plurality ofconnection pipes 40 a, respectively, and connected to refrigerant pipes of a heat exchanger which are not shown. Although not shown, thefirst distributor 8 a also includes an inlet coupled by being welded, for example, to an end of theouter pipe 10 a on a refrigerant upstream side to induce a refrigerant, and a cap coupled by being welded, for example, to an end of theouter pipe 10 a on a refrigerant downstream side to block the flow of refrigerant. However, in the eighth embodiment, theouter pipe 10 a is twisted, for example, in a spiral shape about an axis extending in a longitudinal direction of thedistributor 8. The above may be applied to the second distributor 8 b to theseventh distributor 8 g. In this case, theouter pipes 10 a to 10 g are each an example of an outer pipe or another outer pipe, and the branchedpipes 50 a to 50 g are each an example of a branched pipe or another branched pipe. Also, in the eighth embodiment, it is appropriate that the branchedpipes 50 a to 50 g are respectively connected to the twistedouter pipes 10 a to 10 g on the same side of the distributor 8 (right side in the drawing). In other words, it is appropriate that the branchedpipes 50 a to 50 g are connected to positions where the twistedouter pipes 10 a to 10 g are arranged on a substantially straight line. This is to connect the branchedpipes 50 a to 50 g in the same direction. - Or, the overall structure of each of the
first distributor 8 a to theseventh distributor 8 g may be basically the same as that inFIG. 5 . In this case, as an example, referring to thefirst distributor 8 a, thefirst distributor 8 a also distributes a refrigerant as an example of a fluid flowing through the inside thereof. Thefirst distributor 8 a also includes theouter pipe 10 a having a cylindrical shape, the inlet coupled by being welded, for example, to an end of theouter pipe 10 a on the refrigerant upstream side to induce the refrigerant, and the cap coupled by being welded, for example, to an end of theouter pipe 10 a on the refrigerant downstream side to block the flow of refrigerant. Thefirst distributor 8 a also includes the plurality of branchedpipes 50 a joined to theouter pipe 10 a and connected to the refrigerant pipes of the heat exchanger which are not shown. However, in the eighth embodiment, theouter pipe 10 a is twisted, for example, in a spiral shape about the axis extending in the longitudinal direction of thedistributor 8. The above may be applied to the second distributor 8 b to theseventh distributor 8 g. In this case, theouter pipes 10 a to 10 g are each an example of an outer pipe or another outer pipe, and the branchedpipes 50 a to 50 g are each an example of a branched pipe or another branched pipe. Also, in the eighth embodiment, it is appropriate that the branchedpipes 50 a to 50 g are respectively connected to the twistedouter pipes 10 a to 10 g on the same side of the distributor 8 (right side in the drawing). That is, it is appropriate that the branchedpipes 50 a to 50 g are connected to the positions where the twistedouter pipes 10 a to 10 g are arranged on a substantially straight line. This is to connect the branchedpipes 50 a to 50 g in the same direction. -
FIG. 14 is a bottom view of thedistributor 8 inFIG. 13 according to an embodiment of the disclosure. - When the
outer pipes 10 a to 10 g are twisted in a spiral shape, as illustrated inFIG. 14 , while portions of theouter pipes 10 a to 10 g below thelowest connection pipe 40 g inFIG. 11 are seen from the front, portions of theouter pipes 10 a to 10 g above theconnection pipe 40 g are not seen by overlapping them from the inside. - In a case where the overall structure of each of the
first distributor 8 a to theseventh distributor 8 g is based onFIG. 1 , a cross-sectional view taken along line A-A of each of thefirst distributor 8 a to theseventh distributor 8 g according to the eighth embodiment is the same as that inFIG. 2 , orFIG. 3A or 3B . For example, referring to thefirst distributor 8 a, in the eighth embodiment, the inner diameters D of the reducedflow path parts 51 in the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. Or, the diameters of the front holes 52 or the side holes 53 and 54 of the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. Also, in the eighth embodiment, the insertion lengths L of the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. The above may be applied to the second distributor 8 b to theseventh distributor 8 g. - Also, in the case where the overall structure of each of the
first distributor 8 a to theseventh distributor 8 g is based onFIG. 5 , the cross-sectional view taken along line A-A of each of thefirst distributor 8 a to theseventh distributor 8 g according to the eighth embodiment is the same as a view in which theconnection pipes 40 a to 40 g are removed from the cross-sectional view ofFIG. 2 , orFIGS. 3A or 3B . For example, referring to thefirst distributor 8 a, in this case, the inner diameters D of the reducedflow path parts 51 in the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. Or, the diameters of the front holes 52 or the side holes 53 and 54 of the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. Also, in this case, the insertion lengths L of the plurality of branchedpipes 50 a (three of the branchedpipes 50 a inFIG. 13 ) are provided to be different from each other. The above may be applied to the second distributor 8 b to theseventh distributor 8g. - As such, the eighth embodiment exemplifies that the plurality of branched
pipes 50 has the different inner diameters D and insertion lengths L, and theouter pipe 10 is twisted about the axis extending in the longitudinal direction of thedistributor 8. Accordingly, mixing efficiency of gaseous refrigerant and liquid refrigerant may be improved and refrigerant flow distribution may be adjusted, thereby increasing heat exchange capability. -
FIG. 15 is a view illustrating the overall structure of a heat exchanger unit including adistributor 9 and aheat exchanger 60 according to a ninth embodiment of the disclosure. - The overall structure of the
distributor 9 included in the heat exchanger unit according to the ninth embodiment is the same as that inFIG. 1 or 5 . Thedistributor 9 distributes a refrigerant as an example of a fluid flowing through the inside thereof. Thedistributor 9 includes theouter pipe 10 having a cylindrical shape, theinlet 20 coupled by being welded, for example, to an end of theouter pipe 10 on the refrigerant upstream side to induce the refrigerant, and thecap 30 coupled by being welded, for example, to an end of theouter pipe 10 on the refrigerant downstream side to block the flow of refrigerant. Thedistributor 9 also includes the plurality ofconnection pipes 40 provided in theouter pipe 10, and the plurality of branchedpipes 50 joined to theouter pipe 10 by being inserted into the plurality ofconnection pipes 40, respectively. Or, thedistributor 9 includes the plurality of branchedpipes 50 joined to theouter pipe 10. - A cross-sectional view taken along line A-A of the
distributor 9 inFIG. 15 is the same as that inFIG. 2 , orFIGS. 3A or 3B when the overall structure of thedistributor 9 is the same as that inFIG. 1 . In the ninth embodiment, the inner diameters D of the reducedflow path parts 51 in the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 1 ) are provided to be different from each other. Or, the diameters of the front holes 52 or the side holes 53 and 54 of the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 1 ) are provided to be different from each other. Also, in the ninth embodiment, the insertion lengths L of the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 1 ) are provided to be different from each other. - Also, in a case where the overall structure of the
distributor 9 is the same as that inFIG. 5 , the cross-sectional view taken along line A-A of thedistributor 9 is the same as a view in which theconnection pipe 40 is removed from the cross-sectional view ofFIG. 2 , orFIGS. 3A or 3B . In this case, the inner diameters D of the reducedflow path parts 51 in the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 5 ) are provided to be different from each other. Or, the diameters of the front holes 52 or the side holes 53 and 54 of the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 5 ) are provided to be different from each other. Also, in this case, the insertion lengths L of the plurality of branched pipes 50 (five of the branchedpipes 50 inFIG. 5 ) are provided to be different from each other. - The
heat exchanger 60 included in the heat exchanger unit according to the ninth embodiment performs heat exchange between a refrigerant and air as an example of a fluid distributed by thedistributor 9. Theheat exchanger 60 includes a plurality ofpins 61 arranged at a predetermined interval in a vertical direction, a plurality ofrefrigerant pipes 62 provided in parallel to penetrate passing holes of therespective pins 61 as an example of a plurality of fluid pipes, aheader 63 to collect the refrigerant flowing out of the plurality ofrefrigerant pipes 62, and anexternal connection pipe 64 to flow the refrigerant out of theheat exchanger 60 from theheader 63. - The plurality of branched
pipes 50 of thedistributor 9 is connected to the plurality ofrefrigerant pipes 62 of theheat exchanger 60, respectively. - As such, the ninth embodiment exemplifies that the inner diameters D and the insertion lengths L of the plurality of branched
pipes 50 are different from each other. Accordingly, refrigerant flow distribution may be adjusted, thereby increasing heat exchange capability. - As is apparent from the above, a distributor according to the disclosure can increase the possibility of adjusting fluid flow distribution to a plurality of branched pipes, compared to a case where inner diameters of reduced flow path parts of at least two branched pipes of the plurality of branched pipes and insertion lengths of the at least two branched pipes into the outer pipe are each the same.
- While the disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure as defined by the appended claims and their equivalents.
