Abstract

A heat exchanger has a main body coupling with a positioning plate. A condensing device, two filter plates and two fans are disposed in the main body. The main body has a peripheral base plate, a first air exhaust exit and a first fan opening. A blocking wall is disposed transversely in the main body below the first air exhaust exit. The positioning plate has a peripheral flange, a second air exhaust exit, and a second fan opening. The first and second fans are positioned on the first and second fan openings. The first and second filter plates are positioned on the first and second air exhaust exit. The condensing device is disposed in the main body slantwise. Two heat-insulated sponge pads seal two opposite sides of the condensing device.

Claims

1. A heat exchanger comprising:

a hollow main body coupling with a positioning plate to define an interior of said hollow main body;

said hollow main body having a peripheral base plate, a first air exhaust exit and a first fan opening formed on an upper surface of said main body;

said first air exhaust exit disposed below said first fan opening;

a blocking wall disposed transversely in said main body below said first air exhaust exit;

said blocking wall and a condensing device dividing said interior of said main body into an upper and a lower chamber;

said positioning plate having a peripheral flange to be inserted in said main body;

a second air exhaust exit, and a second fan opening disposed below said second air exhaust exit;

first and second fans positioned on said first fan opening and said second fan opening, respectively;

first and second filter plates positioned on said first air exhaust exit and said second air exhaust exit, respectively;

said condensing device disposed in said main body slantwise, upper end of said condensing device leaning on said main body just above said first air exhaust exit, a lower end of said condensing device leaning on said positioning plate just below said second air exhaust exit;

said condensing device having an upper plate, a lower plate, a plurality of radiation fins disposed between said upper plate and said lower plate spacedly, and a winding cooling pipe passing through said radiation fins vertically;

a vacuum ejector connected to an end of said winding cooling pipe;

a plurality of first through holes formed on said upper plate;

a plurality of second through holes formed on said lower plate;

each of said radiation fins having a plurality of penetration holes to be passed through by said winding cooling pipe; and

two heat-insulated sponge pads sealing two opposite sides of said condensing device.
