OF THE INVENTION

1. Field of Invention

The present invention relates to the field of heat exchanging equipment, in particular, to an air heat exchanging device having an air inducing pipe, a manufacturing method thereof, and an integrated heat-exchanging air-conditioning device.

2. Related Art

Air conditioning equipment is applicable to various places such as machine rooms of communication base stations, other machine rooms, office buildings, hotels, cinemas, and families to condition the temperature of the air, which brings a huge pressure on energy resource. Therefore, how to reduce the energy consumption of the air conditioning equipment has become a common issue encountered by manufacturers and users of the air conditioning equipment.

In the operation of the air conditioning equipment, major energy consumption occurs at the works of cooling or heating. Therefore, the key of reducing the energy consumption of the air conditioning equipment is avoiding using the cooling or heating function as much as possible. Currently, air heat exchanging devices using a nature abundant cool source of a large difference between ambient temperatures in and out of the room are widely used, so as to perform isolated heat exchange on the outdoor air and the indoor air, which effectively reduces the working time for the cooling function or heating function of the air conditioning equipment, thereby effectively reducing the energy consumption. It can be considered that, the air heat exchanging device and the integrated heat-exchanging air-conditioning device may also be used separately without depending on the air conditioning equipment, so as to condition the indoor temperature to a certain extent. The integrated heat-exchanging air-conditioner may also be used separately to improve the temperature conditioning in the room.

The conventional air heat exchanger or integrated heat-exchanging air-conditioner mainly includes an upper flow divider, a heat exchanging core and a lower flow divider. An air outlet of the upper flow divider and an air outlet of the lower flow divider are respectively connected to a fan. An indoor wind channel and an outdoor wind channel separated from each other are disposed in the upper flow divider, the heat exchanging core and the lower flow divider respectively. The indoor wind channels and the outdoor wind channels of the upper flow divider, the heat exchanging core and the lower flow divider communicate with each other to constitute an indoor air flow channel and an outdoor air flow channel. The indoor air flow and the outdoor air flow having a temperature difference may perform heat exchange when flowing through the indoor wind channel and the outdoor wind channel separated from each other in the heat exchanging core in opposite directions. However, the conventional air heat exchanger or integrated heat-exchanging air-conditioner has the following defects.

1. In the conventional air heat exchanging device and integrated heat-exchanging air-conditioning device, the air inlet of the indoor wind channel communicates with the machine room of the communication base station, a great amount of heat is generated by the equipment in the machine room of the communication base station, and the heat is collected by the air heat exchanging device and the integrated heat-exchanging air-conditioning device to enter the indoor wind channel and perform heat exchange with nature cool air in the outdoor wind channel, in this way, the air heat exchanging device and the integrated heat-exchanging air-conditioning device cannot directly perform heat exchange with the hot air generated by the equipment, and therefore, the performance of the devices cannot be fully used, so as to be adverse to energy saving and power consumption reduction.

2. The hot air of the indoor heat generating equipment is first spread in the machine room, the spread hot air has a relatively low temperature, and if the outdoor temperature is high, for example, more than 30° C. in summer of south China, the air heat exchanging device and the integrated heat-exchanging air-conditioning device cannot reduce the temperate in the machine room, thereby greatly limiting the applicable climate range of the air heat exchanging device and the integrated heat-exchanging air-conditioning device.

3. After the hot air is spread in the machine room, it is hard for the air heat exchanging device and the integrated heat-exchanging air-conditioning device to collect and process the hot air.

4. The technical development of the conventional air heat exchanging device and integrated heat-exchanging air-conditioning device emphasizes increasing the energy efficiency ratio under fixed working condition, while neglecting the research on increasing the energy efficiency ratio by changing the working condition of the spot using the devices, thereby being incapable of solving the tropic applicability of the air heat exchanging device and the integrated heat-exchanging air-conditioning device.
