Benefits of technology

[0007]The primary purpose of the present invention is to provide a thermoelectric air conditioning unit and a thermoelectric air conditioner containing the unit with improved energy efficiency ratio.

[0013]The heat transfer water tank is related to a cabinet containing a chamber and a water inlet and a water outlet connecting through the chamber are disposed on the cabinet. Multiple partitioning boards arranged in parallel with one another are disposed in the chamber to separate multiple independent waterways in parallel with one another. A head and a tail of each waterway are connected through in sequence to that of another waterway, and a fin is disposed lengthwise in each waterway to help stabilize water flow.

[0019]The heat transfer water tank is related to a cabinet containing a chamber and a water inlet and a water outlet connecting through the chamber are disposed on the cabinet. Multiple partitioning boards arranged in parallel with one another are disposed in the chamber to separate multiple independent waterways in parallel with one another. A head and a tail of each waterway are connected through in sequence to that of another waterway, and a fin is disposed lengthwise in each waterway to help stabilize water flow.

[0020]When compared to the prior art, the present invention by having the insulation heat transfer coated layer respectively applied on the sides respectively of the heat exchanger and the heat transfer water tank that are attached to the thermoelectric component to substitute the insulation heat transfer plate disposed in the prior art allows direct installation of the thermoelectric component to where between the heat exchanger and the heat transfer water tank to avoid thermal loss of 1˜2□ by shortening the range between the heat exchanger and the thermoelectric component and the range between the heat transfer water tank and the thermoelectric component to upgrade the energy efficiency ratio (EER) of the thermoelectric air conditioning unit and the thermoelectric air conditioner containing the thermoelectric air conditioning unit.

[0021]Those independent waterways connected in sequence with the head and the tail of each water way disposed in a cabinet of the heat transfer water tank of the thermoelectric air conditioning unit of the present invention are each provided with a fin to stabilize the water flow to extend the time of a cooling liquid to contact the water tank. Therefore a contact area between the cooling liquid and the water tank is enlarged to realize sufficient heat exchange to upgrade the general heat transfer efficiency of the water tank to such that is the same as provided by copper heat pipe while significantly lowering the operation cost of the air conditioner.

[0022]Furthermore, a well facilitated air outlet is guaranteed by having a drastic separation of airway from waterway in the thermoelectric conditioners of the present invention containing the thermoelectric air conditioning unit provided with the heat exchanger in a structure as described above. Wherein, the fan is disposed by the side of the heat sink so that an airway is formed among those heat sink fins arranged in parallel with one another and the down slanted heat sink fins cause water drops condensed from vapor in the air to flow downward.

Problems solved by technology

However, the ceramic plate is found with flaws including low efficient ratio of heat or cold transfer and higher energy consumption due to that there will be a thermal loss of 1˜2□ as the temperature of the thermoelectric component after making cool air is transferred through the insulation heat transfer plate to the heat exchanger.

It is true that the heat sink performance is better with the copper heat pipe but the copper heat pipe is also blamed for higher costs and heavier weight.

While the thermoelectric air conditioner is making cool air, a comparatively drastic difference is created between the surface temperature of the heat sink and the ambient temperature, and vapors in the air will condense on the surface of the heat sink and develop small water drops.
