[0019] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. Here, the schematic embodiments and descriptions thereof of the present invention are used to explain the present invention, but do not serve as a limitation to the present invention.

[0020] Figure 1 and Figure 2 show an embodiment of the air heat exchange device of the present invention. The air heat exchange device includes a main housing 10 and a heat exchanger 20. The heat exchanger 20 is bent and arranged in the main housing 10 for heat exchange with the air entering the main housing 10. A first bending surface a is formed on the first side of the main housing 10, and the first bending surface a corresponds to the bent portion of the heat exchanger 20.

[0021] Applying the technical solution of the present invention, by forming a first bending surface a on the first side of the main housing 10 and making the first bending surface a correspond to the bent portion of the heat exchanger 20, the condensed water generated by the bent portion of the heat exchanger 20 can be well received, which is conducive to discharging the condensed water generated by the bent portion of the heat exchanger 20.

[0022] As a preferred embodiment, as Figure 1 shown, in the technical solution of this embodiment, an inclined surface b inclined relative to the horizontal is formed inside the bottom of the main housing 10, and a drain port b1 is provided at the lowest point of the inclined surface b. The condensed water generated on the heat exchanger 20 can be effectively collected through the inclined surface b, and the condensed water is discharged from the heat exchange device through the drain port b1 provided at the lowest point of the inclined surface b. More preferably, in the technical solution of this embodiment, the inclined surface b slopes downward toward the first bending surface a, and the lowest point of the first bending surface a corresponds to the drain port b1. In this way, a funnel-shaped drainage structure formed by the inclined surface b and the first bending surface a is beneficial to discharging the condensed water in the air heat exchange device completely.

[0023] Optionally, in the technical solution of this embodiment, as Figure 1 shown, the heat exchanger 20 includes a connected first bending section 21 and a second bending section 22. The first bending section 21 is arranged in the vertical direction, and the second bending section 22 is arranged inclined relative to the vertical direction. The first bending surface a corresponds to the second bending section 22. By arranging the heat exchanger 20 in a bent shape inside the main housing 10, the space occupied by the heat exchanger 20 inside the main housing 10 can be reduced, which is beneficial to the miniaturization of the air heat exchange device. At the same time, since the first bending surface a corresponds to the second bending section 22, the condensed water generated on the second bending section 22 can be well discharged.

[0024] As Figure 1 shown, optionally, in the technical solution of this embodiment, the second side of the main housing 10 is bent and provided, including a connected second bending surface c and a third bending surface d. A main air return port 11 is formed on the second bending surface c, and an air outlet 12 is formed on the third bending surface d. The second bending surface c corresponds to the first bending section 21, and the third bending surface d corresponds to the second bending section 22. Through the above structural arrangement, it can make the air return and air outlet more targeted relative to the bent heat exchanger 20, and make the air flow act on the heat exchanger 20 more directly.

[0025] Preferably, in the technical solution of this embodiment, the air outlet 12 is located above the main air return inlet 11, and the third bending surface d is inclined upward so that the air outlet direction of the air outlet 12 is upward relative to the horizontal direction. It should be noted that if the air heat exchange device is applied indoors, the cold air can be blown upward relative to the horizontal direction to avoid direct blowing of the cold air, and the sedimentation effect of the cold air is utilized to make the refrigeration more uniform. If the air heat exchange device is applied outdoors and it rains, the rain can be deflected by the air outlet to prevent too much rain from entering the main housing 10. More preferably, the second bending surface c is inclined downward so that the air return direction of the main air return inlet 11 is downward relative to the horizontal direction. If the air heat exchange device is applied indoors, it can return air in cooperation with the above-mentioned air outlet 12 setting method, which is beneficial to air circulation; if the air heat exchange device is applied outdoors, it can also prevent the main air return inlet 11 from attracting rain on rainy days.

[0026] Preferably, in the technical solution of this embodiment, a partition e is provided between the second bending surface c and the third bending surface d. A water through hole e1 is provided on the partition e, and the water through hole e1 corresponds to the inclined surface b. One function of the partition e is to receive the rainwater entering from the air outlet 12 and drain the rainwater to the specified inclined surface b to prevent the rainwater from running around; another function of the partition e is to prevent the air flow from short-circuiting from the main air return inlet 11 to the air outlet 12.

[0027] As Figure 1 shown, as a more preferred implementation manner, a sub-air return inlet 13 that can be opened and closed is formed on the first side of the main housing 10. In addition to the main air return inlet 11, a sub-air return inlet 13 that can be opened and closed is also provided on the main housing 10. When the air heat exchange device needs to further enhance the heat exchange effect, the sub-air return inlet 13 can be opened to increase the air intake volume, so as to meet the heat exchange requirements. In addition, since the sub-air return inlet 13 is provided on the first side of the main housing 10, the sub-air return inlet 13 is opposite to the air outlet 12, which is beneficial to enhancing the heat exchange effect on the heat exchanger 20.

[0028] It should also be noted that in the technical solution of the present invention, the sub-air return inlet 13 can also be connected to a fresh air pipe, so that the air heat exchange device of the present invention can be used as a fresh air fan.

[0029] Preferably, in the technical solution of this embodiment, filter devices are provided on both the main air return inlet 11 and the sub-air return inlet 13 to effectively filter the air entering the main housing 10 and make the air outlet cleaner.

[0030] The present invention also provides an air-conditioning unit, which includes a main unit device and an air heat exchange device connected to the main unit device, and the air heat exchange device is the above-mentioned air heat exchange device. By adopting the above-mentioned air heat exchange device, the waste water generated or received by the air-conditioning unit can be effectively discharged, and the operation stability of the air-conditioning unit can be improved.

[0031] The technical solution of the present invention is different from the structure of conventional air-conditioning units. Compared with the traditional fresh air units and the units that are used in combination with traditional indoor and outdoor units, the technical solution of the present invention divides an air-conditioning unit into three parts, enabling the volume of each part to be relatively reduced, and thus facilitating the portable installation and hidden installation of the air-conditioning unit. At the same time, with the technical solution of the present invention, only two functional modules need to be manufactured, namely the main unit device and the air heat exchange device. The air heat exchange device can be placed outdoors for use as an outdoor unit or indoors for use as an indoor unit. By matching one main unit device with two air heat exchange devices, the assembly of the air-conditioning unit can be achieved. When it is necessary to select air-conditioning units with different powers for different usage places, only the number of air heat exchange devices and main unit devices needs to be adjusted to meet the cooling or heating requirements.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the embodiments of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
