Abstract

A heat exchange device includes a heat exchanger and a water guider. The water guider is arranged on the heat exchanger and has a water guide groove, and condensed water on at least a part of the heat exchanger can flow out through the water guide groove. The heat exchange device has a good drainage performance, can prevent the condensed water from accumulating, and thus improves a heat exchange area and a heat exchange efficiency of the heat exchanger.

First claim

What is claimed is:

1. A heat exchange device, comprising:
a heat exchanger comprising:
a first header and a second header arranged in a direction;
a plurality of flat tubes, each flat tube comprising a first straight section, a second straight section and a bent section, wherein an end of the first straight section of each flat tube is connected to the first header, another end of the first straight section of each flat tube is connected to an end of the bent section of each flat tube, another end of the bent section of each flat tube is connected to an end of the second straight section of each flat tube, another end of the second straight section of each flat tube is connected to the second header, a predetermined included angle is formed between a length direction of the first straight section of each flat tube and a length direction of the second straight section of each flat tube, and the first straight section of each flat tube and the second straight section of each flat tube define a gap therebetween in the direction in which the first header and the second header are arranged; and
fins arranged between the first straight sections of adjacent flat tubes of the plurality of flat tubes and between the second straight sections of adjacent flat tubes of the plurality of flat tubes, respectively,
wherein the heat exchanger comprises a first straight portion, a second straight portion and a bent portion, wherein the first straight portion comprises the first straight sections of the plurality of flat tubes and the fins arranged between the first straight sections of adjacent flat tubes of the plurality of flat tubes, the second straight portion comprises the second straight sections of the plurality of flat tubes and the fins arranged between the second straight sections of adjacent flat tubes of the plurality of flat tubes, the bent portion comprises the bent sections of the plurality of flat tubes, and the bent portion encloses a groove portion that opens toward a gap between the first straight portion and the second straight portion; and

a water guider having a first end and a second end, the first end of the water guider being arranged between the first straight portion and the second straight portion and in contact with the first straight portion and the second straight portion respectively, the second end of the water guider extending to the groove portion, a length direction of the water guider being substantially parallel to a width direction of the heat exchanger, the water guider having a water guide groove, a length direction of the water guide groove being substantially parallel to the length direction of the water guider, the water guide groove allowing condensed water on at least a part of the heat exchanger to flow out therethrough,
wherein the water guider comprises a body, a first end plate and a second end plate, wherein the water guide groove penetrates through the body along a length direction of the body, the body has a first end and a second end in the length direction thereof, the first end plate is arranged at the first end of the body, the second end plate is arranged at the second end of the body, and at least one of the first end plate and the second end plate is provided with a port communicated with the water guide groove,
wherein the body comprises:
a first side plate comprising a first end and a second end in a width direction thereof, at least a part of the first side plate being in contact with one of the first straight portion and the second straight portion;
a second side plate, an end of the second side plate being connected to the first end of the first side plate, and the second side plate being located in the gap between the first straight portion and the second straight portion;
a third side plate, an end of the third side plate being connected to the second end of the first side plate, another end of the third side plate being a free end, the third side plate and the second side plate being arranged opposite to each other in the width direction of the first side plate, and the third side plate being located in the groove portion; and
a fourth side plate arranged at another end of the second side plate, at least a part of the fourth side plate being in contact with the other one of the first straight portion and the second straight portion,
wherein the water guide groove is defined by the third side plate, the first side plate, the second side and the fourth side plate.

2. The heat exchange device according to claim 1 , wherein the first side plate comprises a first section and a second section, an end of the first section is connected to the third side plate, the first section is inclined toward the one of the first straight portion and the second straight portion in a direction from the third side plate to the second side plate, the second section is inclined from another end of the first section toward the one of the first straight portion and the second straight portion in the direction from the third side plate to the second side plate, an inclination angle of the second section is greater than an inclination angle of the first section, and at least a part of the second section is in contact with the one of the first straight portion and the second straight portion.

3. The heat exchange device according to claim 2 , wherein a surface of the second section away from the fourth side plate is in contact with the one of the first straight portion and the second straight portion, and the second side plate is arranged at an end of the second section away from the first section.

4. The heat exchange device according to claim 1 , wherein the first side plate is a straight plate inclined toward the one of the first straight portion and the second straight portion in a direction from the third side plate to the second side plate, and the one of the first straight portion and the second straight portion is in contact with a part of the first side plate adjacent to the first end of the first side plate.

5. The heat exchange device according to claim 4 , wherein the body further comprises a fifth side plate extending from an end of the fourth side plate away from the second side plate, and the fifth side plate and the third side plate are spaced apart in the width direction of the first side plate,
the water guide groove is defined by the third side plate, the first side plate, the second side plate, the fourth side plate and the fifth side plate.

6. The heat exchange device according to claim 1 , wherein a surface of the fourth side plate away from the first side plate is in contact with the other one of the first straight portion and the second straight portion.

7. A heat exchange device, comprising:
a heat exchanger comprising:
a first header and a second header arranged in a direction;
a plurality of flat tubes, each flat tube comprising a first straight section, a second straight section and a bent section, wherein an end of the first straight section of each flat tube is connected to the first header, another end of the first straight section of each flat tube is connected to an end of the bent section of each flat tube, another end of the bent section of each flat tube is connected to an end of the second straight section of each flat tube, another end of the second straight section of each flat tube is connected to the second header, a predetermined included angle is formed between a length direction of the first straight section of each flat tube and a length direction of the second straight section of each flat tube, and the first straight section of each flat tube and the second straight section of each flat tube define a gap therebetween in the direction in which the first header and the second header are arranged; and
