In some embodiments, the heat exchange device further includes a water receiving tray 3 into which the condensed water in the water guide groove 201 can flow.
According to the heat exchange device in the embodiment of the present disclosure, since the water guider 2 having the water guide groove 201 is arranged on the heat exchanger 1, the condensed water on the at least part of the heat exchanger 1 can be guided out, which facilitates drainage and avoids a water blowing phenomenon, thereby improving the reliability and comfort of a product.
Moreover, a water film can be prevented from being formed on flat tubes and fins of the heat exchanger 1, thereby ensuring an effective heat exchange area and a heat exchange efficiency of the heat exchanger 1.
In some embodiments, a length direction of the water guider 2 is substantially parallel to a width direction of the heat exchanger 1. In other words, a length of the water guider 2 substantially extends in the width direction of the heat exchanger 1, that is, the length direction of the water guider 2 is substantially identical with the width direction of the heat exchanger 1.
In some embodiments, a length direction of the water guide groove 201 is substantially parallel to the length direction of the water guider 2. In other words, a length of the water guide groove 201 substantially extends in the length direction of the water guider 2, that is, the length direction of the water guide groove 201 is substantially identical the length direction of the water guider 2.

In other words, two ends of the water guide groove 201 in the width direction of the heat exchanger 1 are lower than rest portions, such that the condensed water in the water guide groove 201 flows out of the two ends of the water guide groove 201 in the width direction of the heat exchanger 1.
In some embodiments, the heat exchanger 1 includes a plurality of heat exchange tubes which are arranged at intervals, and a plurality of water guiders 2 are provided and arranged at intervals in a length direction of the heat exchange tube.

The bent section 133 is twisted at a predetermined torsion angle relative to the first straight section 131 and the second straight section 132 around a length direction of the flat tube 13, and the flat tube 13 is bent at the bent section 133 such that a predetermined included angle is formed between the first straight section 131 and the second straight section 133.
As shown in
The water guider 2 is arranged between the first straight section 131 and the second straight section 132. The condensed water on the heat exchanger 1 can flow from an upper part of the heat exchanger 1 to a contact point between the heat exchanger 1 and the water guider 2, then to the water guide groove 201, and be discharged through the water guide groove 201.
In some embodiments, the heat exchanger 1 includes a first straight portion 101, a second straight portion 102 and a bent portion 103, the first straight portion 101 includes the first straight sections 131 of the plurality of flat tubes 13, and the second straight portion 102 includes the second straight sections 132 of the plurality of flat tubes 13. As shown in
The bent portion 103 includes the bent sections 133 of the plurality of flat tubes 13, and is provided with a groove portion 1031 that opens toward a gap between the first straight portion 101 and the second straight portion 102. As shown in
A first end of the water guider 2 in its width direction is provided between the first straight portion 101 and the second straight portion 102 and is in contact with the first straight portion 101 and the second straight portion 102, respectively, and a second end of the water guider 2 in its width direction extends to the groove portion 1031. As shown in
In other words, the water guider 2 is mounted between the first straight portion 101 and the second straight portion 102 and extends into the groove portion 1031 formed by the bent sections 133 of the plurality of flat tubes 13. As shown in
Further, a length extension direction of the groove portion 1031 is identical with an axial direction of the first header 11, and a length extension direction of the water guider 2 is identical with the length extension direction of the groove portion 1031. The water guide groove 201 extends in the length extension direction of the water guider 2. In other words, the groove portion 1031 extends along a width of the heat exchanger 1, and the water guider 2 is provided with the groove portion 1031 along the width direction of the heat exchanger 1.
As shown in
It can be understood that the position of the water guider 2 is not limited to this in the present disclosure. The water guider 2 may also be arranged at the first straight portion 101, and the condensed water on a part of the first straight portion 101, which is located above the water guider 2, can flow into the water guide groove 201 and flow out through the water guide groove 201. The water guider 2 may also be arranged at the second straight portion 102, and the condensed water on a part of the second straight portion 102, which is located above the water guider 2, can flow into the water guide groove 201 and flow out through the water guide groove 201.
However, the inventor has found that since the fins are arranged both between the first straight sections 131 of adjacent flat tubes 13 and between the second straight sections 132 of adjacent flat tubes 13, but are not arranged between the bent sections 133 of adjacent flat tubes 13, a part of airflow can flow from a gap between adjacent bent sections 133 to an area between the first straight portion 101 and the second straight portion 102 during use of the heat exchanger 1, resulting in air leakage, which affects the air flowing of the heat exchanger 1 and reduces the heat exchange efficiency.
Therefore, in some embodiments, the first end of the water guider 2 in its width direction is arranged between the first straight portion 101 and the second straight portion 102 and is in contact with the first straight portion 101 and the second straight portion 102, respectively, and the second end of the water guider 2 in its width direction extends to the groove portion 1031. The water guider 2 is in contact with the first straight portion 101 and the second straight portion 102 to block a part of the airflow from flowing through the gap between adjacent bent sections 133 to the area between the first straight portion 101 and the second straight portion 102, thereby avoiding the air leakage of the heat exchanger 1 and improving the heat exchange efficiency.
It can be understood that the flat tube 13 may further include a plurality of bent sections 133, and the heat exchanger 1 includes a plurality of bent portions 103. Each bent portion 103 may correspond to one water guider 2.
In some embodiments, the water guider 2 includes a body 21, and the water guide groove 201 penetrates through the body 21 along a length direction of the body 21, and is open on one side of the body 21 in a thickness direction of the body 21. As shown in

The first end plate 22 is arranged at the first end of the body 21, and the second end plate 23 is arranged at the second end of the body 21. At least one of the first end plate 22 and the second end plate 23 is provided with a port 24 which is communicated with the water guide groove 201.

In some embodiments, a groove 220 is formed in an inner side of the first end plate 22 and is communicated with the water guide groove 201. The port 24 is communicated with the groove 220, that is, the groove 220 communicates the water guide groove 201 with the port 24.
In some embodiments, a water guide pipe 4 is connected between the water guider 2 and the water receiving tray 3. The water guide pipe 4 is connected to the port 24, such that the condensed water in the water guide groove 201 is guided into the water receiving tray 3 through the water guide pipe 4, thereby further reducing the water blowing phenomenon.

As shown in
It can be understood that the present disclosure is not limited to the above bent heat exchanger. The heat exchanger 1 in the heat exchange device of the present disclosure may also be the flat plate heat exchanger, as shown in
For a large flat plate heat exchanger, the condensed water on the large flat plate heat exchanger gradually flows from a top of the large flat plate heat exchanger to a bottom of the large flat plate heat exchanger generally depending on the gravity when in use, and finally flows to the water receiving tray. However, since the height of the large flat plate heat exchanger usually exceeds 800 mm, a drainage amount of a single fin is very large, resulting in a large amount of condensed water on the fins at a lower portion of the large flat plate heat exchanger. The condensed water blocks fin windows and gaps between the fins, thereby reducing the effective heat exchange area of the large flat plate heat exchanger, increasing the wind resistance, and reducing the heat exchange efficiency of the heat exchanger.
Therefore, the water guider 2 is arranged on the large flat plate heat exchanger. The condensed water on a part of the heat exchanger 1 is guided out through the water guider 2, so as to avoid a large amount of condensed water on the fins at the lower portion of the large flat plate heat exchanger, thereby increasing the effective heat exchange area of the large flat plate heat exchanger, reducing the wind resistance, and improving the heat exchange efficiency of the heat exchanger.
In some embodiments, the water guider 2 is arranged at a substantially middle position of the flat plate heat exchanger in a height direction, such that the condensed water on an upper half part of the flat plate heat exchanger can be guided into the water receiving tray 3 through the water guider 2.
In some embodiments, the outer surface of the water guider 2 is provided with a flexible material, such as a rubber plastic, or a polyester board. By arranging the flexible material on the outer surface of the water guider 2, it is convenient to mount the water guider 2, so as to avoid damages of the water guider 2 and the heat exchanger 1 caused by the direct contact between the water guider 2 and the heat exchanger 1. In addition, since the contact joint between the water guider 2 and the heat exchanger 1 is prone to corrosion under the action of the condensed water for a long time, by providing the flexible material, the contact joint between the water guider 2 and the heat exchanger 1 can also be prevented from being corroded.
In some embodiments, the outer surface of the water guider 2 is covered with a heat preservation material, which is used for heat insulation, so as to prevent condensed water from being generated on the outer surface of the water guider 2.
