Abstract

The utility model relates to an air exchange device comprising a heat exchange channel, a blower connected with the heat exchange channel and a power source connected with the blower. The heat exchange channel comprises a first obturated channel and a second obturated channel; one end of the first obturated channel is provided with a first air inlet pipe, and the other end is provided with an air outlet; one end of the second obturated channel is provided with a second air inlet pipe, and the other end is provided with a second air outlet pipe. The greenhouse air passing by the first obturated channel exchanges heat with outside air passing by the second obturated channel so that the temperature of air entering a greenhouse from the outside is raised and the temperature in the greenhouse can not be lowered; after the air exchanges heat, the humidity in the greenhouse can be decreased and the content of carbon dioxide can be increased so that the damage to fruits or vegetables by disease and insects can be reduced and the output and the quality of fruits or vegetables can be improved. Because the air exchange device is connected with the greenhouse through pipelines, the greenhouse can not be damaged in the overall structure, is firm and durable and can not be damaged by heavy wind.

The specific embodiment

As shown in Figure 1, a kind of air exchanging apparatus, comprise hot switching path, blower fan and power source, blower fan comprises first blower fan 31 and second blower fan 32, power source comprises first motor 41 and second motor 42, first blower fan 31 is connected with first power source 41, and second blower fan 32 is connected with second power source 42.

As shown in Figure 2, hot switching path comprises the first passage 61 of sealing and the second channel 62 of sealing, first passage 61 and second channel 62 are the circular passage, first passage 61 the inners are connected with first blast pipe 1, first passage 61 outer ends are provided with air outlet 7 and delivery port 10, second channel 62 outer ends are provided with second blast pipe 8, and second channel 62 the inners are provided with second discharge pipe 2.

First passage 61 and second channel 62 are made up of first roll bending 51 and second roll bending 52.

First passage 61 is linked to each other with second roll bending, 52 1 ends by first roll bending 51 with second channel 62 and is that the center rolls and forms with the end that links to each other.

Be connected with hot-air in the first passage 61, be connected with cold air in the second channel 62, also can adopt logical cold air in the first passage 61, logical hot-air in the second channel 62.

As shown in Figure 1, upper end, lower end and the outer end of first passage 61 and second channel 62 are provided with sealing plate 12, and the outer end of second channel 62 is provided with standby hole 9.

As shown in Figure 3, the bottom of first passage 61 and second channel 62 caves inward, and when helping the air generation heat exchange in first passage 61 and the second channel 62, the water that the hot-air in the first passage 61 forms when cooling flows out.

As shown in Figure 3, first blast pipe 1 and second discharge pipe 2 are arranged at the center of first passage 61 and second channel 62 and extend to the bottom from the top of first passage 61 and second channel 62, and first blast pipe 1 and second discharge pipe 2 are positioned at the end sealing of first passage 61 and second channel 62 bottoms.

As shown in Figure 4, first blast pipe 1 and second discharge pipe 2 tube wall that is positioned at first passage 61 and second channel 62 is provided with several air vents 13.

As shown in Figure 1, second blower fan, 32 air inlets are provided with screen pack 11, and dusts such as particle contained in the air that enters in the booth are filtered out, and the air that enters in the booth is purified.

The air inlet of first blower fan 31 links to each other with booth, and the air outlet of first blower fan 31 links to each other with first blast pipe, 1 one ends, the other end of

first blast pipe

1 and 61 inner linking to each other of first passage, and first passage 61 outer ends are provided with air outlet 7 and delivery port 10.

Second blower fan, 32 air inlets communicate with atmosphere, second blower fan, 32 air outlets link to each other with second blast pipe, 8 one ends, second blast pipe, 32 other ends link to each other with second channel 62 outer ends, and the inner of second channel 62 links to each other with second discharge pipe, 2 one ends, and second discharge pipe, 2 other ends link to each other with booth.

The interior air-flow direction of the flow direction of air and second channel 62 is opposite in the first passage 61.

In order further to reduce the loss of heat, can coat one deck insulation material in the hot switching path outside.

The course of work: the air in the booth enters first passage 61 by first blower fan 31 and first blast pipe 1, enter the atmosphere from the air outlet 7 of first passage 61 outer ends, extraneous air enters second channel 62 by second blower fan 32 and second blast pipe 8, enter booth by second discharge pipe 2 that is arranged on second channel 62 the inners again, because the air themperature height in the booth, extraneous air themperature is low, when air process first passage 61 in booth and extraneous air process second channel 62, heat exchange will take place, extraneous air themperature is raise, air themperature in the booth reduces, because extraneous air themperature raises, so the temperature in the booth is reduced, thereby kept the stable of canopy temperature, air in the booth can produce condensed water when temperature reduces in first passage 61, condensed water flows out by the delivery port 10 that is arranged on first passage 61 outer ends, again because the interior air humidity of booth is big, and extraneous air ratio is dry, so the air in the booth is when entering atmosphere, will take away the moisture in the part booth, outside air also can make the humidity in the booth reduce after entering booth, thereby reduced the disease and pest of melon and fruit or vegetables, after air and outside air exchange in booth, the content of the carbon dioxide in the booth is increased.

Can be with the outer end of first passage 61 as air intake, inner as outlet air end, delivery port 10 is arranged on the inner, flow out in order to make condensed water this moment, can first passage 61 and the bottom of second channel 62 be set to flat or outside protrusion, simultaneously with second channel 62 the inners as air intake, above-mentioned effect also can be realized as outlet air end in the outer end.
