1. A heat exchanger for facilitating heat exchange between a predetermined amount of water and a predetermined amount of refrigerant, comprising:
a heat exchanger housing having a water inlet, a water outlet, a refrigerant inlet, a refrigerant outlet, and a cover detachably provided on said heat exchanger housing, an upper water chamber provided on an upper portion of said heat exchanger housing, and is communicated with said water outlet; a lower water chamber provided on a lower portion of said heat exchanger housing, and is communicated with said water inlet; and at least one heat exchanging pipe extended between said upper water chamber and said lower water chamber, wherein water having a relatively low temperature is arranged to enter said heat exchanger through said water inlet and temporarily store in said lower water chamber, wherein said water is pumped up said heat exchanger housing through said heat exchanging pipes and temporarily store in said upper water chamber and leaves said heat exchanger through said water outlet, wherein said heat exchanging pipe comprises a pipe body, a plurality of inner heat exchanging fins inwardly extended from said pipe body, and a plurality of outer heat exchanging fins outwardly extended from said pipe body; wherein said refrigerant is guided to enter said heat exchanger through said refrigerant inlet and flow through an exterior of outer heat exchanging fins of said heat exchanging pipes for performing heat exchange with said water flowing through said corresponding inner heat exchanging fins of said heat exchanging pipes, wherein heat is absorbed by said refrigerant which becomes evaporated, wherein vapor of said refrigerant is then guided to leave said heat exchanger through said refrigerant outlet. |
