The effect that drainage improves, but it is preferably provided with 2,3.It, can also be in addition, scaly structure body 5 can be contacted with fin 2
It does not contact.
Then, the drainage of flat tube 3 is investigated in such a way.About heat exchanger 1, using in embodiment 1
In the identical heat exchanger of manufactured heat exchanger 1.About the scaly structure body 5 between fin 2 and fin 2, the height is set to be
1mm makes length 2mm, and the short side 31 of flat tube 3 is formed in and cutting out.
Next, the flat tube 3 for being formed with scaly structure body 5 is immersed in the water, after making the sufficiently water suction of flat tube 3,
The pull-up from water by flat tube 3.Then, measurement is just after the weight and pull-up of the flat tube 3 after pull-up in water by 3 points
The weight of flat tube 3 when clock.Using the difference of the weight after just pull-up and after 3 minutes as residual amount, calculates and pass through 3
The amount for the moisture that flat tube 3 is included after minute.As a result, residual amount are as follows: the surplus of the water after pull-up after 3 minutes is rigid
50% of amount of moisture after rigid pull-up.By the way that scaly structure body 5, the row of heat exchanger 1 are arranged between fin 2 and fin 2
Aqueous to improve, the residual amount of heat exchanger 1 is greatly reduced.
Heat exchanger 1 involved in present embodiment 2 from the description above, heat exchanger 1 flat tube 3 it is short
The surface on side 31 and be to be provided as the scaly structure body 5 of protrusion member between the fin 2 of plate.In such case
Under, flat tube 3 surface generate condensed water by the capillarity of scaly structure body 5 and the effect of gravity and
It moves on the short side 31 of air, and flows downwards.Condensed water is by from the upper surface of flat tube 3, lower surface or flat tube 3
Joint portion between fin 2 promptly drains, and can reduce the case where being kept, being detained, and also can be avoided or reduce condensation
Water becomes frost and adheres to this case.Therefore, it can be improved the heat exchange between the working fluid and air of the inside of flat tube 3
Efficiency.
In addition, scaly structure body 5 can by cutting out, punch process etc. formed, can be with identical with flat tube 3
Alloy or the alloy of identical principal component are formed for material, therefore do not need to prepare the special material of scaly structure body 5,
It can be expected that the attachment of the raising and frost of drainage performance avoids.
In addition, scaly structure body 5 is configured in parallel between adjacent fin 2, and in the surface along flat tube 3
Shape, therefore the condensed water for being attached to the surface of flat tube 3 can promptly be drained.
Embodiment
In embodiment 2, the Length of the scale 52 of scaly structure body 5 of the configuration between the fin 2 of plate is carried out
Investigation.Specifically, to relationship and Length of the scale 52 between the Length of the scale 52 and drainage speed of scaly structure body 5
Relationship between air drag when frosting is investigated.
Firstly, being formed with aluminium alloy etc. is the fin 2 of material and the length of short side 31 for the flat tube 3 of 2mm, and make
The distance between 2 flat tubes 3 of adjacent configuration are 15mm, and the heat exchanger 1 of height 30cm, width 30cm is made.Then, exist
The surface of the short side 31 of flat tube 3 and be that 2 scaly structure bodies 5 are equally spaced configured between the fin 2 of plate, investigation
Residual amount ratio and air drag.Firstly, in order to find out residual amount ratio, after the weight to heat exchanger 1 measures,
It flows water from the top of heat exchanger 1, and water is made to stop flowing after a certain time, measure its weight after 1 minute.So
Afterwards, find out from water flow through before weight subtract the resulting value of the weight after running water through as residual amount ratio.In addition, about
Air drag flows through -10 DEG C of anti-icing fluid in heat exchanger 1 as working fluid, and then measurement makes air with 1m/s's
Air drag when circulating in the heat exchanger 1 for becoming the state for being attached with frost of wind speed after 1h.
Fig. 9 is the relationship shown between the Length of the scale 52 of scaly structure body 5 and residual amount ratio and air drag
Scatter diagram.Black circle shows residual amount ratio, and black triangle shows air drag ratio.In addition, in Fig. 9, in not set flakey
In the state of tectosome 5, Length of the scale 52 is indicated with zero.As shown in Fig. 9, about residual amount ratio, if being configured at flat tube
The Length of the scale 52 of 3 scaly structure body 5 becomes larger, then the residual amount ratio of heat exchanger 1 becomes smaller therewith.It is thought that because
For following reason: being increased by the Length of the scale 52 of scaly structure body 5, due to capillarity, produced on the surface of flat tube 3
The movement of raw condensed water becomes to be more easier, and draining is promoted.In addition, if the Length of the scale 52 of scaly structure body 5 becomes
Bigger than substantially 4mm or so, then residual amount ratio rises slightly.It is thought that because of following reason: the surface of scaly structure body 5
Product increases, and the condensed water before draining as a result, is largely kept.
On the other hand, if the Length of the scale 52 for being configured at the scaly structure body 5 of flat tube 3 becomes larger, air drag ratio
Slow rising is showed therewith.This is because: the area that frost can adhere to increases with the increase of Length of the scale 52, by
The surface of scaly structure body 5 is attached in frost and makes air drag than increasing.In addition, if the scale of scaly structure body 5
Length 52 becomes bigger than substantially 6mm, then air drag is than showing increase sharply.It is thought that because of following reason: with
Length of the scale 52 increases, and the amount of accompanying frost increases, and is accompanied by this, the amount for being attached to the frost of scaly structure body 5 increase and
Air drag becomes larger.
According to result above: when 2 scales are arranged as protrusion member and between the fin of parallel plate 2
In the case where tubular structure 5, preferably the Length of the scale 52 of scaly structure body 5 is substantially 6mm or less.In addition, flat tube 3
Short side 31 is 2mm, therefore can be defined: preferably substantially 3 times or less of the length of short side 31.
