Description

Heat exchange device

The present invention relates to a heat exchange device, and more particularly to a heat exchange device disposed in a ceiling.

Keeping indoor air fresh is the foundation for ensuring people's health. With the improvement of people's requirements for ventilation and ventilation quality, various ventilation devices, such as heat exchange devices, have been developed.

Specifically, the Chinese patent application CN102305448A discloses a full heat exchanger. As shown in FIG. 17, the full heat exchanger includes an indoor air intake port disposed on the front side of the casing 801, an indoor fresh air exhaust port 810, and corresponding to each other. In the outdoor fresh air inlet 808 and the outdoor air exhaust port 809 on the rear side of the casing 801, the partition 802 in the casing 801 divides the inside of the casing 801 into a heat exchange chamber 804 and an exhaust chamber 805. A heat exchange core 813 is disposed in the heat exchange chamber 804, and an exhaust device is disposed in the exhaust chamber 805.

When the air is ventilated, the outdoor air enters the first air inlet 816 of the heat exchange core 813 from the outdoor fresh air inlet 808, and is discharged from the first air outlet 817 of the heat exchange core 813 to enter the lower volute 829 of the exhaust device. Finally, it is discharged from the indoor fresh air exhaust port 810; the indoor air enters the second air inlet 818 of the heat exchange core 813 from the indoor air inlet port, and is discharged from the second air outlet port 819 of the heat exchange core 813 to enter the exhaust device. Upper volute 826, finally from outdoor air The exhaust port 809 is exhausted.

Since the first air inlet 816 is not facing the outdoor fresh air intake 808, after the outdoor fresh air enters from the outdoor fresh air intake 808, it must first turn downwards before entering the first air inlet 816, and the air passage is bent. It is also relatively large, so the wind resistance when entering the wind is relatively large, and the air volume is relatively small. Similarly, the wind path of the wind is also relatively large, so the wind resistance of the wind is relatively large, and the air volume is relatively small. Therefore, the ventilation effect is poor. In addition, since the gas path of the heat exchange element 813 is relatively short, the passage time of the air in the heat exchange element 813 is relatively short, so that sufficient heat exchange cannot be performed, and thus the heat exchange efficiency of the heat exchanger is relatively low.

Moreover, the maintenance panel of the all-heat exchanger is disposed at the bottom of the machine, and the full heat exchanger is disposed in the ceiling of the house, so it is very inconvenient to disassemble. Also, the dust inside the heat exchanger will be dropped on the maintenance personnel when disassembling.

Chinese patent CN2180929Y discloses an indoor and outdoor two-way ventilator. As shown in FIG. 18, the ventilator adopts a hexagonal heat exchange core 913, and the gas path is relatively long, so the heat exchange efficiency is relatively high. In addition, since the second intake port 918 faces the return air 909, the indoor air can enter the heat exchange core 913 directly after entering the return air inlet 909, and the second air inlet 918 and the second air outlet 919 are opposed to each other. The road bends less and the wind resistance is smaller. However, when entering the wind, the outdoor air first passes through the air inlet volute 924, and then enters the first air inlet 916 through the air outlet of the air inlet scroll 924. Because the wind speed is large at this time, the first air inlet 916 is relatively small. Therefore, the wind resistance will be very large, so the ventilation effect is relatively poor.

In addition, since the heat exchange core 913 of the ventilator is placed longitudinally, Therefore, the ventilator has a large volume.

Moreover, for the above two ventilators, the indoor air must pass through the heat exchange element to be discharged outside. However, in the seasons where the indoor and outdoor temperatures are close in spring and autumn, heat exchange is not required. At this time, the indoor air is discharged to the outside through the heat exchange element, which only increases the wind resistance, resulting in a decrease in ventilation efficiency.

At present, some ventilation devices are provided with a side ventilation path, for example, Chinese patent application CN102939504A, etc., in the spring and autumn, the indoor air is directly discharged to the outside through the side ventilation path. However, setting the bypass air passage increases the volume of the ventilator.

The invention provides a heat exchange device for the problems of low heat exchange efficiency, large wind resistance and large volume of the existing heat exchange device.

The heat exchange device provided by the present invention comprises: a housing having a first partition and a second partition, the first partition separating the internal space of the housing into a heat exchange chamber and a ventilation chamber, The second partition partitions the ventilation chamber into a first air chamber and a second air chamber, and a portion of the housing that forms the heat exchange chamber is provided with an air inlet and a return air inlet opposite to each other, and the housing is configured a portion of the first air chamber is provided with a fresh air outlet, and a portion of the casing constituting the second air chamber is provided with an air outlet; a ventilation unit is disposed in the ventilation chamber for the first air chamber The air inside is discharged from the fresh air outlet, and the air in the second air chamber is discharged from the air outlet; the heat exchange element is disposed in the heat exchange In the cavity, the heat exchange element includes a plurality of first gas paths and a plurality of second gas paths independent of each other, the first gas path including a first gas inlet and a first gas outlet opposite to each other, the second gas path The second air inlet and the second air outlet are opposite to each other; the first air outlet is in communication with the first air chamber, and the second air outlet is in communication with the second air chamber, the first air inlet is facing the The tuyere, the second air inlet faces the return air outlet.

By adopting the above structure, the heat exchange device of the present invention reduces the bending of the air passage, thereby reducing the wind resistance, improving the ventilation effect, and improving the heat exchange efficiency. And by using the above-described method of setting the heat exchange element, the volume is reduced.
