1. A heat exchanger comprising:
a first heat exchanging unit including a housing and a plate having four corner areas secured together, and having four outer peripheral sides spaced from each other for forming a slot between said outer peripheral sides of said housing and said plate, said housing and said plate each including a corrugated structure and having a flowing channel formed between said corrugated structures of said housing and said plate and communicating with said slot that is formed between said outer peripheral sides of said housing and said plate, said housing and said plate each including a recess formed therein for forming a first higher side platform and a first lower side surface, and said housing and said plate each including two orifices formed in said first higher side platform, and each including two apertures formed in said first lower side surface, and a second heat exchanging unit including a casing and a board disposed below said plate of said first heat exchanging unit and having four corner areas secured together and secured to said corner areas of said housing and said plate, and having four outer peripheral sides separated from each other for forming a slit between said outer peripheral sides of said casing and said board, said casing and said board each including a corrugated structure and having a passageway formed between said corrugated structures of said casing and said board and communicating with said slit that is formed between said outer peripheral sides of said casing and said board, said casing and said board each including a depression formed therein for forming a second higher platform and a second lower side surface, said second higher side platforms of said casing and said board being located below said first lower side surfaces of said housing and said plate, and said second lower side surfaces being located below said first higher side platforms of said housing and said plate, and said casing and said board each including two holes formed in said second higher side platform and aligned with said orifices of said housing and said plate respectively, and said casing and said board each including two openings formed in said second lower side surface and aligned with and communicating with said apertures of said housing and said plate respectively. |
