As if adopting this structure, because the inside pipe wall face 36a of heat transfer tube group 32a is level and smooth, and the heat transfer caliber is thin, thereby does not need fluting processing, can reduce processing charges greatly, and while heat exchanger unit is lightness more.
And because of heat transfer caliber difference, finned type heat exchanger 30a, 30b are from just distinguishing in appearance.Even be mixed in the assembly project, also can will have the heat-transfer pipe configuration assembling according to the rules really of several pipe interior shapes, thereby obtain heat exchanger unit stable, that possess the regulation heat-exchange capacity.
(the 4th embodiment)
Fig. 7 is the stereogram after the heat exchanger unit bending machining of the 4th embodiment, and Fig. 8 is the stereogram before its bending machining, and Fig. 9 is that it wants portion's cutaway view.In Fig. 7, this heat exchanger unit 40 is made up of the finned type heat exchanger 40a of the gas inflow side W1 that is positioned at the air-flow shown in the arrow W and the finned type heat exchanger 40b that is positioned at gas outflow side W2.Finned type heat exchanger 40a is made of a plurality of fins set 41a of spaced and parallel setting in accordance with regulations and the heat transfer tube group 42a that roughly connects fins set 41a orthogonally and be arranged in the shape that crawls.Equally, finned type heat exchanger 40b is made of a plurality of fins set 41b of spaced and parallel setting in accordance with regulations and the heat transfer tube group 42b that roughly connects fins set 41b orthogonally and be arranged in the shape that crawls.The heat exchanger unit is implemented 90 degree bending machining, the outdoor air conditioner of can packing into the radius of curvature R of regulation.Among Fig. 8 of state, finned type heat exchanger 40a and finned type heat exchanger 40b are separated before the expression bending machining.The length of heat transfer tube group 42a is only than the long dL of heat transfer tube group 42b.Therefore, as shown in Figure 7, both ends of the surface flush after the bending machining.Secondly, among Fig. 9, the inside pipe wall face shape 46a of heat transfer tube group 42a is an even surface.The inside pipe wall face shape 46b of heat transfer tube group 42b is formed by continuous helical form protuberance 44b and slot part 45b.In addition, air-flow W flows in fins set 41a and fins set 41b in the direction of arrows, carries out heat exchange with fluid in the pipe internal flow of heat transfer tube group 42a and heat transfer tube group 42b.
If adopt such formation, because the heat transfer tube group 42a in the finned type heat exchanger 40a is that inside pipe wall face shape 46a is the smooth tubes of tabular surface, therefore can lightness, and fluting processing, processing cost reduces significantly.And the heat transfer tube group 42a of finned type heat exchanger 40a is different mutually with the inside pipe wall face shape of the heat transfer tube group 42b of finned type heat exchanger 40b.Their length is also different.So, even mixing the heat-transfer pipe that caliber is identical, the inside pipe wall flute profile is different in the same assembly project, also can with heat-transfer pipe really according to the rules the luggage that is configured into join, can obtain the qualification rate height and have the heat exchanger unit of regulation heat-exchange capacity.
(the 5th embodiment)
To the 5th embodiment is in conjunction with Fig. 7, Fig. 9, Figure 10 explanation.In Fig. 7, heat exchanger unit 40 is formed by being positioned at the fin type heat interchanger 40a of the gas inflow side W1 of the air-flow shown in the arrow W and the finned type heat exchanger 40b that is positioned at gas outflow side W2.Finned type heat exchanger 40a is a plurality of fins set 41a that are provided with by spaced and parallel in accordance with regulations, and the heat transfer tube group 42a that roughly connects fins set 41a orthogonally and be arranged in the shape that crawls forms.Equally, finned type heat exchanger 40b is made up of a plurality of fins set 41b of spaced and parallel setting in accordance with regulations and the heat transfer tube group 42b that roughly connects fins set 41b orthogonally and be arranged in the shape that crawls.In Fig. 9, the internal face 46a of heat transfer tube group 42 is processed into even surface.The inside pipe wall face 46b of heat transfer tube group 42b is then by becoming continuous helical form protuberance 44b and slot part 45b to form.Air-flow W flows between fins set 41a and fins set 41b in the direction of arrows, and carries out heat exchange with fluid in the pipe internal flow of heat transfer tube group 42a and heat transfer tube group 42b.
When the heat exchanger unit of above-mentioned formation used as the condenser of the kind of refrigeration cycle of air conditioner, the fluid that flows in heat-transfer pipe was with the A1 side inflow of gas phase state from finned type heat exchanger 40b.The fluid that flows into shunt up and down because of branching portion 43b, in flowing through heat transfer tube group 42b after, in the heat transfer tube group 42a of inflow finned type heat exchanger 40a, collaborate again and go out to the A2 effluent at branching portion 43a.The fluid that flows in heat-transfer pipe carries out heat exchange with air-flow W in flow process, change into liquid condition from gas phase state through gas-liquid two-phase state thus.
When the heat exchange unit of above-mentioned formation uses as the evaporimeter of the kind of refrigeration cycle of air conditioner, the fluid that in heat-transfer pipe, flows with gas-liquid two-phase state from the A2 side inflow.The fluid that flows into is shunted up and down at branching portion 43a, and the heat-transfer pipe of the heat transfer tube group of flowing through 42a also flows into heat transfer tube group 42b, goes out at branching portion 43b interflow and to the A1 effluent once again.The fluid that flows in heat-transfer pipe carries out heat exchange with air-flow W in the way of flowing, thus, though still gas-liquid two-phase state, but from the low state of mass dryness fraction to the high state variation of mass dryness fraction.
If adopt such formation, because the internal face shape 46a of heat transfer tube group 42a is a tabular surface in the finned type heat exchanger 40a, that is, use smooth tubes, thereby can lightness, not needing fluting processing, processing charges also can reduce significantly.
On the other hand, use smooth tubes can cause that heat-exchange capacity reduces.Figure 10 represents the relation of the mass dryness fraction of the fluid that flows in the heat transfer coefficient of heat exchanger and the heat-transfer pipe.Curve E represents the heat transfer coefficient of the heat transfer tube group 42a that heat transfer property is low, and curve F represents the heat transfer coefficient of the heat transfer tube group 42b that heat transfer property is high.As shown in Figure 10, in low mass dryness fraction field, heat transfer coefficient all is a low value, and in high mass dryness fraction field, the heat transfer coefficient value of curve F representative sharply raises, and the heat transfer coefficient of curve E representative then slowly improves.When the condenser as the kind of refrigeration cycle of air conditioner uses, the fluid that in heat-transfer pipe, flows with gas phase state to the high heat transfer tube group 42b side inflow of heat transfer property, through flowing out from the low heat transfer tube group 42a of heat transfer property with liquid phase state behind the two-phase state.Use the smooth heat transfer tube group 42a of inside pipe wall face in low mass dryness fraction side, like this,, can realize that the heat-transfer pipe cost reduces though heat transfer property reduces a little.
