The specific embodiment
Below, the preferred embodiment that present invention will be described in detail with reference to the accompanying is provided.
Air interchanger provided by the present invention as depicted in figs. 1 and 2, comprise box-shaped main body 10, be located at the heat exchanger 30 in the main body 10.11 both sides, side, outside of main body 10 are respectively equipped with extraneous gas inflow entrance 15 and internal gas outlet 16, and 12 both sides, side, indoor are respectively equipped with internal gas inflow entrance 17 and extraneous gas outlet 18.
This heat exchanger 30 comprises the first suction face 33 of the air that flows into extraneous gas inflow entrance 15 sides, the second suction face 34 that flows into the air of internal gas inflow entrance 17 sides, the first discharge face 35 of the first suction face, 33 opposition sides, the second discharge face 36 of the second suction face, 34 opposition sides as shown in Figure 2.The first suction face 33 is connected by air supply channel 31 with the first discharge face 35, and the second suction face 34 is connected by exhaust passage 32 with the second discharge face 36.Air supply channel 31 and exhaust passage 32 are spaced from each other towards cross one another direction in heat exchanger 30.In this heat exchanger 30, the outdoor air (dotted arrow) by air supply channel 31 carries out heat exchange with room air (solid arrow) by exhaust passage 32.
This air interchanger, when exhaust blowing unit 40 operation, the room air that flow into internal gas inflow entrance 17 flows to exhaust blowing unit 40 sides by the exhaust passage 32 of heat exchanger 30, and through exhaust blowing unit 40 internally gas discharge outlet 16 discharge.And when air feed blowing unit 50 operation, the outdoor air that flow into extraneous gas inflow entrance 15 flows to air feed blowing unit 50 by the air supply channel 31 of heat exchanger 30, and discharges from extraneous gas outlet 18 through air feed blowing unit 50.When carrying out this ventilation action,, so can make indoor thermal loss minimum because room air carries out heat exchange in cross one another mode by heat exchanger 30 inside with outdoor air.
In addition, this air interchanger, because air feed and exhaust blowing unit 40,50 are arranged in the diagonal of extraneous gas inflow entrance 15 and internal gas inflow entrance 17, it is different with the air inhalation power that acts on the second heat exchanger 30b side therefore to act on the first heat exchanger 30a side.Therefore, generally speaking, fast in the first heat exchanger 30a side than the second heat exchanger 30b side away from air feed blowing unit 50 near air feed blowing unit 50 by air (from the first suction face, the 33 leaked-in airs) flow velocity of heat exchanger 30 air supply channels 31.And air (from the second suction face, the 34 leaked-in airs) flow velocity of the exhaust passage 32 by heat exchanger 30 is also fast than the first heat exchanger 30a side away from exhaust blowing unit 40 in the second heat exchanger 30b side near exhaust blowing unit 40.So, when the flow velocity of the flow velocity of the first suction face, 33 both sides and the second suction face, 34 both sides not simultaneously, may cause the heat exchanger effectiveness of heat exchanger 30 to reduce.
But, the present invention as shown in Figure 3, by making the first heat exchanger 30a side air supply channel 31a different with the flow resistance of the second heat exchanger 30b side air supply channel 31b, and make the first heat exchanger 30a side exhaust passage 32a different with the flow resistance of the second heat exchanger 30b side exhaust passage 32b, can address the above problem thus.
For this reason, the first heat exchanger 30a is alternately laminated with cross one another form by ripple pitch little corrugated plating 37a, 37b relative big corrugated plating 38a, 38b with the ripple pitch with the second heat exchanger 30b, and inserts dividing plate 39a, 39b respectively and form between each corrugated plating.That is, the first heat exchanger 30a and the second heat exchanger 30b are with identical morphosis.Just, each heat exchanger 30a, 30b are provided with the direction difference, form air supply channel 31a by the little corrugated plating 37a of ripple pitch among the first heat exchanger 30a, and form air supply channel 31b by the big corrugated plating 38b of ripple pitch among the second heat exchanger 30b.The structure of exhaust passage 32 then in contrast.That is, form exhaust passage 32a by the big corrugated plating 38a of ripple pitch among the first heat exchanger 30a, and form air supply channel 32b by the little corrugated plating 37b of ripple pitch among the second heat exchanger 30b.
This is to increase for the flow resistance that makes the little corrugated plating 37a of ripple, 37b side.Therefore, in the air supply channel 31 near the flow resistance of the air supply channel 31a of the first heat exchanger 30a of air feed blowing unit 50 air supply channel 31b greater than the second heat exchanger 30b.On the contrary, in the exhaust passage 32 near the flow resistance of the exhaust passage 32b of the second heat exchanger 30b of exhaust blowing unit 40 exhaust passage 32a greater than the first heat exchanger 30a.
Therefore, air interchanger provided by the present invention because the flow air velocity flow profile can become evenly on the whole in the air supply channel 31 of heat exchanger 30 or exhaust passage 32, so can improve heat exchanger effectiveness.And,, therefore can improve ventilation effect, but also can reduce the noise that flows than in the past because that this structure and the existing air interchanger that utilizes flow deflector are compared its air flow resistance is little.
Fig. 4 is another embodiment of heat exchanger.The example of Fig. 4 is different from the example of Fig. 3, and heat exchanger 300 forms as one.This heat exchanger 300 is alternately laminated with cross one another direction with the exhaust corrugated plating 340 that is used to form exhaust passage 320 by the air feed corrugated plating 330 that is used to form air supply channel 310, and between air feed corrugated plating 330 and exhaust corrugated plating 340 insertion dividing plate 350 and forming.And air feed corrugated plating 330 is more little the closer to air feed blowing unit 50 ripple pitches, and exhaust corrugated plating 340 is more little the closer to exhaust blowing unit 40 ripple pitches.
This is for the air flow resistance by air supply channel 310 is increased gradually from extraneous gas inflow entrance 15 sides to air feed blowing unit 50 sides, thereby makes the velocity flow profile of heat exchanger 300 air supply channels 310 keep even on the whole.And, make by exhaust passage 320 air flow resistance internally gas inflow entrance 17 sides to exhaust blowing unit 40 sides increase gradually, thereby make the velocity flow profile of heat exchanger 300 exhaust passages 320 keep even on the whole.
In sum, air interchanger provided by the present invention, because the flow resistance near air feed blowing unit side in the air supply channel of heat exchanger is big relatively, and the flow resistance near exhaust blowing unit side is big relatively in the exhaust passage of heat exchanger, therefore can make the air velocity by heat exchanger air supply channel and exhaust passage distribute maintenance on the whole evenly.Thereupon, can improve the heat exchanger effectiveness of heat exchanger.
And, even because the present invention is not provided with flow deflector in the suction face side of heat exchanger, also can make air velocity distribute maintenance evenly by heat exchanger, therefore can be more in the past than the structure of simplifying air interchanger.
