Abstract

The utility model relates to a cold and hot bidirectional scavenger fan. The utility model mainly solves the defects that the existing scavenger fans can not carry out air charging and air discharging simultaneously and the existing scavenger fans do not have heat exchanging function. The utility model is provided with two impellers which are respectively arranged on the two shaft extending positions of a motor. The opposite sides of the two impellers are respectively provided with air outlets whose airflows are communicated with each other to form bidirectional reverse air passages whose airflows are isolated from each other. The peripheries of the motor and the impellers in a box body are provided with heat exchangers, and each heat exchanger is formed by the mutual overlapping of corrugated metal sheets. The utility model not only can charge air and discharge air simultaneously, but also has the function of heat exchange, so the air exchanging effect can be improved and energy source can be saved.

Description

The changes in temperature dual direction ventilating fan
The utility model relates to a kind of ventilation fan, particularly a kind of changes in temperature dual direction ventilating fan that cold and hot air inside and outside the air-conditioned room can be carried out heat exchange.
At present, the ventilation fan of selling on the market all is the unidirectional ventilation fan of a fan blade basically.And this ventilation fan does not have heat recovery function yet, as summer air-conditioned room cold air and winter air-conditioned room warm air discharged in vain, like this because of no heat-exchange device, be a very big waste to the energy.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of ventilation effect is good, the changes in temperature dual direction ventilating fan of heat-exchange device with energy savings but provide.
The purpose of this utility model is achieved in that it includes casing, motor, impeller, unique distinction is: impeller is two (1,4), be separately positioned on two shaft extension places of motor 2, the opposite side of two impellers respectively is provided with the gas outlet that air-flow communicates, and constitutes the isolated each other two-way reciprocal air flue of air-flow; Be provided with heat exchanger 3 around motor in the casing 6 and the impeller, it is made of the corrugated sheet metal that is stacked mutually.
Advantage of the present utility model is simple in structure, can carry out air intake and air draft simultaneously, and ventilation effect is good.Owing to have heat exchanger, make the inside and outside cold and hot air of air-conditioned room can carry out heat exchange by it, thus but energy savings.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional perspective structural representation (arrow is represented the circulation exchange of indoor-outdoor air) of heat exchanger 3 among Fig. 1.
Fig. 3 is a heat exchange effect schematic diagram of the present utility model.
Each structure shown in the drawings is exactly embodiment of the present utility model.Among the figure, 1 is the back impeller, and 2 is the 40W monophase machine, 3 is heat exchanger, adopts thin aluminum sheet to strike out corrugated, and the closed assembly welding is made again, for easy for installation, can be made into four parts and be arranged in edge place, impeller periphery angle, 4 is preceding impeller, 5 is front shroud, and 6 is casing, and 7 is every vane, 8 is back shroud, and 9 is indoor turbid air, and 10 for being discharged to outdoor air after heat exchange, 11 is outdoor bright air, and 12 is laggard to indoor air through heat exchange.Casing of the present utility model, impeller etc. all adopt plastic mould pressing to form.Heat exchanger adopts 0.2mm thin aluminum sheet punching press weldering system to form.The utility model is because of there being coaxial double-wind-impeller, therefore air intake and air draft synchronously, and ventilation effect is good.Especially have heat exchange action, through actual measurement, 26 ℃ of turbid air in the air-conditioned room are discharged to outdoor with 30.1 ℃ behind heat exchanger; Outdoor 32 ℃ bright air behind heat exchanger with in 27.9 ℃ of inlet chambers.So just saved the energy widely.
