(b) Description of the Prior Art: 10 A heat exchanger of the prior art mounted in an indoor thermoelectric air conditioner is provided with a heat transfer plate, and multiple heat sink fins are fixed on one side of the heat transfer plate. Those heat sink fins are vertically erected on the side of the heat transfer plate. The indoor heat exchanger is connected to a cold air generation chip by means of an insulation heat transfer plate; and the cold air 15 generated from the chip is transferred to those heat sink fins. In the prior art, the heat exchanger is put in erected position for use. A fan is usually mounted to the upper edge of the heat transfer plate to blow air crossing those heat sink fins to produce cold air delivered into the room. Whereas the temperature difference between surfaces of those heat sink fins and the ambient air is comparatively greater, 20 vapors in the air will condense on surfaces of those heat sink fins into small water drips and the fan is located above the heat transfer plate, the direction of the air blown by the fan is the same as that those water drips drop. Therefore, those water drips flowing in a direction of following that the air is blown could easily blockade the air direction. 25 For the purposes of this specification the word "comprising" means "including but not limited to", and the word "comprises" has a corresponding meaning. Also a reference within this specification to a document is not to be taken as an admission that the disclosure therein constitutes common general knowledge in Australia. 30 SUMMARY OF THE INVENTION The primary purpose of the present invention is to provide an exchanger that warrants well- facilitated air vane and an indoor thermoelectric air conditioner containing the heat exchanger. 35 To achieve the purpose, a heat exchanger of the present invention is 2 comprised of a heat transfer plate containing an elevation area for it to be erected on a bottom in an outer casing of an indoor thermoelectric air conditioners; and multiple heat sink fins arranged in parallel with one another are fixed on a surface of a side of the heat transfer plate abutted to the elevation area. All those heat sink fins are in 5 parallel with the elevation area and their free ends are inclined downward in the direction facing the elevation area. According to a structure described above, those heat sink fins are soldered and fixed to the heat transfer plate. A hydrophilic film is coated on an outer surface of each heat sink fin. 10 An insulation heat transfer layer is form on an outer surface of one side of the heat transfer plate opposite to the side fixed with those heat sink fins. The heat transfer plate is made of aluminum and the insulation heat transfer layer is related to a layer of aluminum oxide (A1 2 0 3 ) formed on the surface of the heat transfer plate using micro-arc oxidization (MAO) method. 15 The indoor thermoelectric air conditioner of the present invention is provided with an outer casing; and the heat exchanger is disposed on a bottom of the outer casing. The heat exchanger is provided with a heat transfer plate and an elevation area for the heat exchanger to be erected on a bottom in the outer casing of the indoor thermoelectric air conditioner. Multiple heat sink fins arranged in parallel 20 with one another are fixed on one side abutted to the elevation area of the heat transfer; and a thermoelectric component is adhered to another side of the heat transfer plate. A fan is fixed 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. Those heat sink fins on the heat exchanger are arranged in parallel with the elevation area and their free ends are 25 inclined downward in a direction facing the elevation area. The fan in the outer casing is fixed to one side of the heat transfer plate of the heat exchanger; and the air blown by the fan is in a direction in parallel with the surface of the heat transfer plate and the elevation area of the heat transfer plate. According to a structure described above, those heat sink fins are soldered 30 and fixed to the heat transfer plate. A hydrophilic film is coated on an outer surface of each heat sink fin. An insulation heat transfer layer is form on an outer surface of one side of the heat transfer plate opposite to the side fixed with those heat sink fins. The heat transfer plate is made of aluminum and the insulation heat transfer 35 layer is related to a layer of aluminum oxide (A1 2 0 3 ) formed on the surface of the heat 3 transfer plate using micro-arc oxidization (MAO) method. In comparison with the prior art, the present invention provides multiple beneficial results including insurance of well-facilitated air vane. Whereas those heat sink fins of the heat exchanger of the present invention are arranged in parallel with its 5 elevation area and all their free ends are inclined downward in a direction facing the elevation area. Therefore, when the heat exchanger is in erected portion for use, the fan blows the air from side of the heat sink fins, and an airway is formed between two heat sink fins in parallel with each other and any water drip condensed on the heat sink will flow downward by central gravity since the heat sink fin is made inclined 10 downward to clear away from the airway. The hydrophilic film coated on the outer surface of each heat sink also help frustrate vapors in the air to condense on the heat sink fin to further warrant well-facilitated air vane. With the heat exchanger mounted in the indoor thermoelectric air conditioner and the fan disposed on one side of the heat transfer plate to blow the air 15 towards the surface of the heat transfer plate and the elevation area of the heat transfer plate, an airway is formed between two abutted heat sink fins arranged in parallel with each other and the slanted heat sink fin causes water condensed from vapors in the air to flow down due to central gravity to separate the waterway from the airway in warranting well- facilitated air vane. 20 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an exploded view showing a construction of an indoor thermoelectric air conditioner of the present invention. Fig. 2 is a side view showing a construction of a heat exchanger of the present invention. 25 Fig. 3 is a rear view showing the construction of the heat exchanger of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A heat exchanger of the present invention is comprised of a heat transfer plate 4 made of aluminum; an elevation area 1 is disposed to the heat transfer plate 4 30 for it to be erected on a bottom in an outer casing 7 of an indoor thermoelectric air conditioner; multiple heat sink fins 5 arranged in parallel with one another are fixed on one side of the heat transfer plate 4 at where abutted to the elevation area 1; those heat sink fins 5 are fixed by soldering to the heat transfer plate 4 and arranged in parallel with the elevation area 1 of the heat transfer plate 4. All free ends of those heat sink 35 fines 5 are inclined downward in a direction facing the elevation area 1. 4 To prevent vapors in the air from being condensed into water drips on a surface of each heat sink fin 5 when the thermoelectric air conditioner is generating cold air; a hydrophilic film is formed on an outer surface of each heat sink fin 5 using electrophoresis (or by coating nano-ulra hydrophilic liquid). 5 A layer of aluminum oxide (A1 2 0 3 ) is formed using micro-arc oxidization (MAO) method on the aluminum transfer plate 4 on one side opposite to the side fixed with heat sink fins 5 to improve heat or cold transfer efficiency of the heat exchanger for saving energy. In a preferred embodiment of an indoor thermoelectric air conditioner of 10 the present invention contains a heat exchanger 3 erected on a bottom in an outer casting 7 of the air conditioner; and the heat exchanger 3 is attached with a thermoelectric component (not illustrated) on a side opposite to the side fixed with those heat sink fins 5. A fan 8 is disposed in the outer casing 7 to blow hot air or cold air radiated from the heat exchanger 3 to a space where the hot or cold air is 15 needed. The fan 8 in the outer casing 7 is fixed to a side of the heat transfer plate 4 of the heat exchanger 3 for the air is blown in a direction in parallel with a surface of the heat transfer plate 4 and the elevation area 1 of the heat transfer plate 4 at the same time. That is, the air is blown by the fan 8 towards sides of those heat sink fins. An airway is formed between any two abutted heat sink fins 5 in parallel with each other 20 and a flow direction of water on a surface of each heat sink fin 5 and that of the air blown by the fan 8 are different from each other to avoid possible blockade of the airway due to that the water flows in the same direction as that of the air. In the preferred embodiment, a drainage pan 6 is disposed below the heat exchanger 3 to collect water condensed on the surface of each heat sink fin 5 and discharge the water 25 out of the outer casing 7 thus to warrant a well-facilitated air vane of the thermoelectric air conditioner. Of course, those heat sink fins 5 are not necessarily arranged in strictly parallel with one another as long as each and all of them are inclined downward; and 30 the direction of the air blown by the fan 8 may be completely in parallel with the surface of the heat transfer plate 4 and the elevation area of the heat transfer plate 4 at the same time, or in parallel with the surface to dissipate heat of each heat sink fin 5 as long as the direction of the air blown by the fan 8 is different from that of the water flows on the surface of each heat sink fin 5 to warrant maintaining a well-facilitated 35 air vane. 5
