Heat exchanger and an air conditioner containing the heat exchanger

Abstract

A heat exchanger and an indoor thermoelectric air conditioner containing the heat exchanger, the heat exchanger includes a heat transfer plate provided with an elevation area for the plate to be erected on bottom in outer casing of the air conditioner; multiple heat sink fins parallel with one another are fixed on one side of the plate at where abutted to the elevation area; free ends of those fins are inclined downward in a direction facing the elevation area; a fan blows the air from both sides of each fin to create airway between any two abutted fins; water of vapors in the air condensed on surface of each fin fall off downward due to central gravity thus to separate waterway from airway to warrant well-facilitate air vane of the air conditioner; and outer surface of each fin being applied with a hydrophilic film to frustrate condensation to further insurance of the well-facilitated air vane.

1 . A heat exchanger comprising a heat transfer plate; an elevation area for the heat transfer plate to be erected on a bottom in an outer casing of an indoor thermoelectric air conditioner being provided to the heat transfer; multiple heat sink fins arranged in parallel with one another being fixed on one side of the heat transfer plate abutted to the elevation area; those heat sink fins being arranged in parallel with the elevation area; and all free ends of those heat sink fins being inclined downward in a direction facing the elevation area. 
   
   
       2 . The heat exchanger as claimed in  claim 1 , wherein those heat sink fins are fixed by soldering to the heat transfer plate. 
   
   
       3 . The heat exchanger as claimed in  claim 1  or  2 , wherein a layer of hydrophilic film is disposed on an outer surface of each heat sink fin. 
   
   
       4 . The heat exchanger as claimed in  claim 1  or  2 , wherein those an insulation heat transfer layer is disposed on an outer surface of one side of the heat transfer plate opposite to the side of the heat transfer plate where those heat sink fins are fixed. 
   
   
       5 . The heat exchanger as claimed in  claim 4 , wherein the heat transfer plate is made of aluminum, and the insulation heat transfer layer is related to an aluminum oxide (Al 2 O 3 ) layer formed using micro-arc oxidization (MAO) method on the surface of the aluminum heat transfer plate. 
   
   
       6 . An indoor thermoelectric air conditioner comprising an outer casing; a heat exchanger erected on a bottom in an outer casting of the air conditioner; a heat transfer plate being disposed to the heat exchanger; an elevation area being disposed to the heat transfer plate for the heat transfer plate to be erected on the bottom in the outer casing of the indoor thermoelectric air conditioner; multiple heat sink fins arranged in parallel with one another being fixed to one side of the heat transfer plate at where abutted to the elevation area; the heat exchanger being attached with a thermoelectric component on a side opposite to the side fixed with those heat sink fins; a fan being disposed in the outer casing to blow hot air or cold air radiated from the heat exchanger to a space where the hot or cold air is needed; the fan in the outer casing being fixed to a side of the heat transfer plate of the heat exchanger for the air is blown in a direction in parallel with a surface of the heat transfer plate and the elevation area of the heat transfer plate at the same time. 
   
   
       7 . The indoor thermoelectric air conditioner as claimed in  claim 6 , wherein those heat sink fins are fixed by soldering to the heat transfer plate. 
   
   
       8 . The indoor thermoelectric air conditioner as claimed in  claim 6  or  7 , wherein a layer of hydrophilic film is disposed on an outer surface of each heat sink fin. 
   
   
       9 . The indoor thermoelectric air conditioner as claimed in  claim 6  or  7 , wherein those an insulation heat transfer layer is disposed on an outer surface of one side of the heat transfer plate opposite to the side of the heat transfer plate where those heat sink fins are fixed. 
   
   
       10 . The indoor thermoelectric air conditioner as claimed in  claim 9 , wherein the heat transfer plate is made of aluminum, and the insulation heat transfer layer is related to an aluminum oxide (Al 2 O 3 ) layer formed using micro-arc oxidization (MAO) method on the surface of the aluminum heat transfer plate.
