Patent ID: 7631687

Claim:
A heat exchanger used in a sealed equipment cabinet, said heat exchanger comprising: a chassis comprising a bottom plate having a plurality of first perforations; a heat-exchange module comprising a plurality of spaced first heat sink fins arranged on first side of said bottom plate for cooperatively defining a first air flow channel and having second perforations corresponding to said first perforations, a plurality of spaced second heat sink fins arranged on second side of said bottom plate for cooperatively defining a second air flow channel and having third perforations corresponding to said first perforations, and a plurality of heat pipes penetrated through said second perforations of said first heat sink fins, said first perforations of said bottom plate and said third perforations of said second heat sink fins by a press fit operation, so that said first heat sink fins and said second heat sink fins are securely fixed onto said first and second sides of said bottom plate, respectively; first and second baffle plates disposed on opposite sides of the topmost first heat sink fin; third and fourth baffle plates disposed on opposite sides of the lowermost second heat sink fin; a first fan disposed on said first side of said bottom plate; a second fan disposed on said second side of said bottom plate; and a first fixing plate and a second fixing plate respectively protruded from an air outlet of said first fan and an air outlet of said second fan, said first and second fixing plates having several fixing holes sheathed around adjacent heat pipes; wherein said first baffle plate is adjacent to said first fan and substantially disposed between said first fan and said second baffle plate.
