In the air conditioner constituted as described above, in case where when coagulating for blowdown firing, to it
Function and effect are illustrated.
Firstly, illustrating the flowing and heat exchange action of refrigerant.Refrigerant is from the inflow side as plate fin laminated body 13
The 1st collector flow path 14 flow into 16 groups of refrigerant flow path.It is flowed into 16 groups of refrigerant flow path of refrigerant of each plate fin 11, from
As refrigerant flow path 16 remove trackside go trackside refrigerant flow path 16a to the return road side refrigerant flow path as return road side
16b turns back, and the refrigerant circuit of refrigeration system is then flowed to from the 2nd collector flow path 15 as outlet side.
Then, when refrigerant is when refrigerant flow path 16 flows, with the plate fin lamination for passing through plate fin laminated body 13
Between gap 19 air carry out heat exchange.
At this point, being formed in the refrigerant of plate fin 11 by reducing about the flowable refrigerant flow path 16 of refrigerant
The sectional area of the concave groove of flow path can be realized the thinning of flow path.As a result, compared with the heat conducting pipe mode the case where, energy
It is enough that miniaturization is promoted while improving heat exchanger effectiveness.
In addition, heat exchanger 5 carries out heat exchange to the air in the gap 19 passing through plate fin lamination, become the air
Cold air or heating.When making cold air to air progress heat exchange, the hydrogenesis in air is handed in heat sometimes
The surface of parallel operation 5.Since heat exchanger 5 is obliquely arranged, condensed water is as shown in Figure 9 along the plate wing for constituting heat exchanger 5
The downside ora terminalis 11a of piece 11 is flowed down downwards.
Herein, heat exchanger 5 is plate fin laminated type heat exchanger, therefore as shown in Figure 10, in the ora terminalis of plate fin 11
The column such as part are equipped with the protrusion 18 (18a (18aa, 18ab), 18b) for forming the gap of plate fin to each other.Condensed water can
The inclination upper section of the downside ora terminalis 11a of the plate fin 11 of flowing arranges the multiple 1st protrusion 18aa set, is located at than downside ora terminalis
11a inwardly (inboard) at defined distance, therefore condensed water will not meet the 1st protrusion 18aa and by tangling along plate wing
The downside ora terminalis 11a of piece 11 is flowed down downwards.Moreover, in the present embodiment, the 2nd protrusion 18ab of the lowest part of plate fin 11
It is set on the downside of fin near ora terminalis 11a, therefore, the condensed water flowed down is met the 2nd protrusion 18ab and tangled, from the 2nd protrusion
18ab drips downwards.
Therefore, it can narrow to the 2nd protrusion 18ab's for receiving the drip tray 7 of the condensed water to drip from heat exchanger 5
Size M, and inclination size (size when heat exchanger projects below vertical) L (Figure 10 ginseng of not inclined heat exchanger 5
According to), it being capable of densification.In addition, 7 densification of drip tray can be made, therefore a part that can reduce drip tray 7 enters wind path 4
Or the limitation for having to make wind path 4 to narrow etc., performance deterioration etc. caused by being able to suppress because of above-mentioned reason.
In addition, in the present embodiment, according to above-mentioned explanation it is found that being set to the downside ora terminalis 11a's of plate fin 11
In lower projection 18a, the 1st protrusion 18aa of part not opposite with drip tray 7 is located at least in than the 2nd protrusion 18ab backup plate fin
11 inside setting, it is attached that the 2nd protrusion 18ab positioned at the part opposite with drip tray 7 is configured to be set to ora terminalis on the downside of fin
Closely.
Therefore, in heat exchanger 5, the 2nd protrusion 18ab is located at the downside of the plate fin 11 of the part opposite with drip tray 7
Near ora terminalis 11a, the intensity of the smaller fin ora terminalis of intensity is improved to provide its rigidity.Moreover, the 2nd protrusion 18ab is arranged
Near the ora terminalis 11a of downside, thus increase than the heat exchange effective area of the 2nd protrusion 18ab in the inner part, heat exchanger effectiveness improves
Corresponding amount.
Specifically, as shown in fig. 6, when protrusion 18 being arranged near the downside ora terminalis 11a in plate fin 11, than setting
The 2nd protrusion 18ab near the ora terminalis 11a of downside is the higher heat of heat exchanger effectiveness at refrigerant flow path 16 in the inner part
Effective area X is exchanged, is greater than the 1st protrusion 18aa's being arranged in a manner of being located at (inboard) in the inner part than downside ora terminalis 11a
The heat exchange effective area Y of inside.Therefore, heat exchanger effectiveness improves corresponding amount.
In addition, lower projection 18a (18aa, 18ab) does not contribute its own heat exchange effectively.Therefore, when under reduction
It can increase when lateral process 18a (18aa, 18ab) itself to the contributive heat exchange area of the heat exchange of plate fin 11, Neng Goujin
One step improves heat exchanger effectiveness.It is therefore preferable that lower projection 18a (18aa, 18ab) and upper lateral process 18b are contracted to required
Minimal size.
It is arranged as described above, working as a protrusion in the protrusion column for be arranged in the downside ora terminalis 11a of plate fin 11 in lower side
When near edge 11a, the rigidity that can take into account plate fin 11 improves and the raising of heat exchanger effectiveness.
In addition, being configured to be greater than plate wing from the size Z (referring to Fig. 6) that the downside ora terminalis 11a of the 1st protrusion 18aa is gone inwardly
The size in the gap in the gap 19 (referring to Fig. 4) of piece 11 to each other.Therefore, even if condensed water spreads the downside ora terminalis of plate fin 11
Gap 19 between the fin plate 11 of 11a and flow down, can also make that it does not encounter with the 1st protrusion 18aa and part is flowed downwards as former state
Under.Therefore, can prevent, which becomes condensed water, hangs over the 1st protrusion for being set to inclination upper section not opposite with drip tray 7
The case where state of 18aa is dripped using the 1st protrusion 18aa as starting point to condensed water, can be more reliably prevented from and drip.
In addition, protrusion 18 (18a, 18aa, 18ab, 18b) makes its top become dome shape (including substantially as shown in Figure 8
Dome shape).A part and the 1st protrusion 18aa of the condensed water under the downside ora terminalis 11a stream of plate fin 11 are become as a result,
Encounter such situation, since the top of the 1st protrusion 18aa is dome shape (including substantially dome shape), condensed water is also difficult to
Hang over the top.Therefore, condensed water can be more reliably prevented from condensed water as former state along ora terminalis 11a on the downside of fin with the 1st protrusion
18aa drips for starting point.
In addition, being equipped with upper lateral process in the downside ora terminalis 11a of plate fin 11 and the upside side ora terminalis 11b column in heat exchanger 5
18b, the upper lateral process 18b of the upside side ora terminalis 11b are configured to be set near the ora terminalis 11b of upside.Therefore, it can be improved plate fin
The rigidity of the 11 upside part ora terminalis 11b, and heat exchanger effectiveness improves due to the increase of heat exchange effective area.Therefore, energy
Enough rigidity for more effectively taking into account plate fin 11 improve and the raising of heat exchanger effectiveness.
In addition, in this embodiment, heat exchanger 5 is located at wind path 4 with the part downside ora terminalis 11a of its plate fin 11
The mode of upstream side configures.Thereby, it is possible to caused by the gravity of the condensed water under inhibiting the downside ora terminalis 11a in plate fin 11 to flow
Whereabouts effect, condensed water can partially drip on the lower from than plate fin 11.Therefore, drip tray 7 can be made more compact.And
And increase the quantity for the 2nd protrusion 18ab being set near the downside ora terminalis 11a of plate fin 11, rigidity can be further increased
And heat exchanger effectiveness.
(embodiment 2)
Figure 11 indicates the protrusion of the plate fin of embodiment 2.In the present embodiment, it is set to the protrusion 18 of plate fin 11
(18a, 18aa, 18ab, 18b) cuts forming in the form of along refrigerant flow path 16 as shown in figure 11 and is formed, the incision configured ends
Edge E is configured to opposite with the flow direction W of air of folded interflow in plate fin 11.
As a result, in protrusion 18 (18a, 18aa, 18ab, 18b), centainly same can be spaced between making plate fin lamination
When, keep the dead water region for being easy to generate in the downstream side of protrusion 18 (18a, 18aa, 18ab, 18b) minimum and is being cut into
Shape ora terminalis E plays leading edge effect in part.And it is opposite with the flow direction W of air due to cutting the part forming ora terminalis E, it is right
The flow resistance of air becomes smaller.Therefore, the flow path resistance for being able to suppress the flow passage region of plate fin laminated body 13 increases, and further increases
Heat exchanger effectiveness.
In addition, the incision of protrusion 18 (18a, 18aa, 18ab, 18b) is shaped along the refrigerant of plate fin laminated body 13
The mode of flow path 16 is formed.It therefore, there is no need to from the concave plane between the refrigerant flow path in the direction that refrigerant flow path 16 intersects
21 settings are used to form the thinning portion of wall thickness for cutting forming.Therefore, it is with protrusion 18 (18a, 18aa, 18ab, 18b) protuberance is made
Mode that is cylindric and being formed is compared, and the concave plane size of refrigerant flow path to each other can be made to narrow and do not need setting wall thickness change
The amount in thin portion, capable of correspondingly making plate fin 11, in other words heat exchanger minimizes.
The function and effect of other structures are identical as embodiment 1, omit the description.
More than, to air conditioner of the invention, it is illustrated using above embodiment, but the present invention is not limited to
This.That is, all aspects of embodiments of the present invention are to illustrate, it is not considered that being limited, the scope of the present invention is not by upper
