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.

Abstract: A thermoelectric air conditioning unit and a thermoelectric air conditioner containing the unit; the unit includes thermoelectric component and heat exchanger; the heat exchanger is provided with heat transfer plate; multiple heat sink fins are disposed on one side of the heat transfer plate and the other side of the heat transfer plate is adhered to the thermoelectric component; another side of the component is attached with a water tank; the component is secured at where between the exchanger and the tank; the exchanger and the tank are respectively coated on one side an insulation heat transfer layer; the air conditioner is provided with an outer casing containing multiple thermoelectric air conditioning units; a fan is fixed at the outer casing; heat loss is reduced for 1˜2 ? due to that the coated layer that substitutes a heat transfer plate so to upgrade energy efficiency ratio of the thermoelectric air conditioning unit and that of the thermoelectric air conditioner containing the unit.

Abstract: A heat transfer water tank adapted to an air conditioner and a manufacturing process thereof includes a cabinet containing a chamber; the cabinet includes a casing containing the chamber and provided on both sides each an opening; a sealing plate is fixed to seal up each opening; a sealing plate is disposed with a water inlet and a water outlet connecting through the chamber of the casing; the chamber is divided into multiple waterways by partitioning boards; on two opposite ends of any two abutted boards being each disposed with a water trough to permit waterways to be connected through one another; and a fin being provided in each waterway; the water upon entering from the water inlet passes each waterway before finally flowing out of the water outlet to enter into a next cycle; the water flow is given sufficient contact with the fin and the board to increase contact area and extend contact time for sufficient heat exchange to upgrade heat transfer efficiency.
