Abstract:
A thermoelectric module (100) comprising at least two heat exchanging units (1, 2, 3) connected in series is provided. Each heating exchanging unit comprises: a main body (10, 20, 30) having an inlet (14, 24, 34) for intaking cooling medium; a thermoelectric element (11, 21, 31) provided in the main body (10, 20, 30) which divides the main body (10, 20, 30) into a working chamber (12, 22, 32) formed with a working medium outlet (124, 224, 324) and a waste heat chamber (13, 23, 33) formed with a waste medium outlet (134, 234, 334). The working medium outlet (124, 224, 324) of one of two neighboring heat exchanging units is connected with the inlet (14, 24, 34) of the remaining of the two neighboring heat exchanging units. The temperature in the working chambers may be increased or decreased step by step to achieve further heating/cooling, thus achieve an enlarged temperature variable range. A temperature controlled vehicle seat comprising the thermoelectric module is also provided.
