Abstract

A heat-exchange device comprises a first heat exchanger defining an upper end and a lower end. A second heat exchanger defines an upper end connected to the upper end of the first heat exchanger and a lower end spaced apart from the lower end of the first heat exchanger in a substantially longitudinal direction such that a predetermined angle between the first heat exchanger and second heat exchanger is between about 0 and 180°. A wind-guide member is disposed between the first heat exchanger and second heat exchanger for guiding wind toward the first heat exchanger and second heat exchanger.

First claim

What is claimed is:

1. A heat-exchange device comprising:
a first heat exchanger defining an upper end and a lower end;
a second heat exchanger defining an upper end connected to the upper end of the first heat exchanger and a lower end spaced apart from the lower end of the first heat exchanger in a substantially longitudinal direction such that a predetermined angle between the first heat exchanger and second heat exchanger is between about 0 and 180°; and
a wind-guide member disposed between the first heat exchanger and second heat exchanger for guiding wind toward the first heat exchanger and second heat exchanger,
wherein the wind-guide member is a substantially V-shaped wind-guide plate,
wherein an upper edge of a first side wall of the wind-guide plate is connected to an upper portion of the first heat exchanger and an upper edge of a second side wall of the wind-guide plate is connected to an upper portion of the second heat exchanger, and
wherein a predetermined quantity of through holes are formed in the first and second side walls of the wind-guide plate.

2. The heat-exchange device according to claim 1 , wherein the lower end of the first heat exchanger is substantially aligned with the lower end of the second heat exchanger, a height of each of the first and second heat exchangers in a vertical direction is “H,” a distance from a lowest point of the wind-guide member to a lowest point of each of the first and second heat exchangers in the vertical direction is “H 1 ,” and 0≦H 1 /H≦4/5.

3. The heat-exchange device according to claim 1 , wherein a water-guide groove is formed at an outer side of a bottom portion of the wind-guide plate.

4. The heat-exchange device according to claim 1 , wherein the first and second side walls of the wind-guide plate are in substantial shape of arcs protruding toward each other.

5. The heat-exchange device according to claim 1 , wherein the device comprises further a first side plate mounted on a side of the first and second heat exchangers in a substantially transversal direction and a second side plate mounted on another side of the first and second heat exchangers in the transversal direction, two ends of the wind-guide member in the transversal direction being connected to the first and second side plates, respectively.

6. The heat-exchange device according to claim 5 , wherein the wind-guide member is a substantially V-shaped wind-guide plate, an upper edge of a first side wall of the wind-guide plate is spaced apart from the upper end of the first heat exchanger by a predetermined distance, and an upper edge of a second side wall of the wind-guide plate is spaced apart from the upper end of the second heat exchanger by a predetermined distance.

7. The heat-exchange device according to claim 6 , wherein, in any substantially horizontal plane passing through the wind-guide plate, a distance between the first and second side walls of the wind-guide plate is “L 2 ,” a distance between the first side wall of the wind-guide plate and the first heat exchanger is “L 1 ,” a distance between the second side wall of the wind-guide plate and the second heat exchanger is “L 3 ,” and 0≦L 2 /(L 1 +L 2 +L 3 )≦0.95.

8. The heat-exchange device according to claim 1 , wherein the wind-guide member is either of an olivary wind-guide plate and a tube defining either of a substantially circular and diamond cross-section.

9. The heat-exchange device according to claim 1 , wherein the wind-guide member includes a plurality of wind-guide plates divided into a first group and second group, the first group is spaced apart from the second group in a substantially transversal direction, and the wind-guide plates of each of the groups are spaced apart from each other in a substantially vertical direction.

10. The heat-exchange device according to claim 9 , wherein each of the wind-guide plates is either of a substantially flat and arcuate plate and the wind-guide plates of the first group are in substantially one-to-one correspondence with the wind-guide plates of the second group.

11. The heat-exchange device according to claim 1 , wherein the wind-guide member includes a plurality of wind-guide plates spaced apart from each other in a substantially vertical direction and having shapes different from each other.

12. The heat-exchange device according to claim 1 , wherein the first and second heat exchangers are formed by either of bending a single substantially flat-plate heat exchanger and two separate substantially flat-plate heat exchangers connected with each other.

13. The heat-exchange device according to claim 1 , wherein, in a horizontal plane passing through the wind-guide plate, a distance between the first side wall and second side wall of the wind-guide plate is “L 2 ,” a distance between the first side wall of the wind-guide plate and the first heat exchanger is “L 1 ,” a distance between the second side wall of the wind-guide plate and the second heat exchanger is “L 3 ,” L 2 /(L 1 +L 2 +L 3 )=1 in a substantially horizontal plane passing through a top edge of the wind-guide plate, and 0≦L 2 /(L 1 +L 2 +L 3 )≦0.95 in substantially horizontal planes passing through other parts of the wind-guide plate than the top edge of the wind-guide plate.
