Abstract:
1. A heat exchanger uses water liquid and vapor phases transformation to enhance heat exchange performance, comprising: a primary heat exchanger including an air fan which has a heat exchange coiled tube located therein for circulating system refrigerant; a water vaporization device for generating water vapor from water and air intake to allow passing air and water molecules to generate heat exchange function and add moisture; and an auxiliary heat exchanger located at a front side of an air intake side of the water vaporization device having an upper heat exchange tube on an upper end and a lower heat exchange tube on a lower end thereof, the upper heat exchange tube and the lower heat exchange tube being connected and communicated by a plurality of heat tubes, the upper heat exchange tube containing a plurality of branch tubes in a transverse manner in a middle section thereof, the branch tubes having two ends communicating respectively with a first chamber and a second chamber, and being sealed by partitions to form a surrounding area outside the branch tubes, the surrounding area communicating with the heat tubes and being filled with a first refrigerant medium, the first chamber communicating with a third water delivery tube, the second chamber communicating with a first water delivery tube, the lower heat exchange tube containing a plurality of branch tubes in a transverse manner in a middle section thereof, the branch tubes having two ends communicating respectively with a third chamber and a fourth chamber, and being sealed by partitions to form a surrounding area outside the branch tubes, the surrounding area communicating with the heat tubes and being filled with the first refrigerant medium, the third chamber communicating with a third refrigerant delivery tube, the fourth chamber communicating with a second refrigerant delivery tube.
