FIELD: instrument making industry; other industries; production of the thermoelectric devices. ^ SUBSTANCE: the invention is pertaining to the field of the thermoelectric instrument making, in particular, to the designs of the conditioners for the air cooling. The thermoelectric air conditioner contains the thermoelectric battery consisting of two stages, the heat exchanger for then airflow and the flow-through heat exchanger of the heat-removing water. The stages are formed by the alternated branches manufactured accordingly from the n-type and p-type semiconductors in series connected to the electric circuit by means of the three types of the commutation plates. The first type of the commutation plates simultaneously plays the role of the heat transfer between two stages. The third type of the commutation plates is supplied with the ribs disposed outside along the stream of the cooled air in the one plane with the contact site. The second type of the commutation plates is supplied with the ribs disposed inside the flow-through heat exchanger along the stream of the heat-removing liquid and perpendicularly to the plane of the contact site. The channel of the flow-through is located between the pairs representing the first and second stages of the thermal battery and is separated from the latter by means of the heat-insulation layer. The purpose of the invention is the increased reliability of the device, the increased difference of the temperatures on the hot and cold heat exchangers at the expense of cascading of the thermal batteries and also the increase of the thermal dynamic efficiency of the heat exchanger due to the optimal usage of the heat-exchange area. ^ EFFECT: the invention ensures the increased reliability of the device, the increased difference of the temperatures on the hot and cold heat exchangers at the expense of cascading of the thermal batteries, and also the increase of the thermal dynamic efficiency of the heat exchanger due to the optimal usage of the heat-exchange area. |
