PURPOSE: A technology for improvement of the heat-exchanger unit out of the number of the problems and an improved heat-exchanger unit, and a thermoelectric refrigerating system is provided which have built therein a thermoelectric module which is improved in respect of productivity, maintenance and component compatibility. CONSTITUTION: A plurality of series-connected heat exchanger units (50, 51, 52) are provided with thermoelectric modules (5), and turbulators (55) are provided on both surfaces of these thermoelectric modules (5). Each of the turbulators (55) is covered with a lower shell (53) or an upper shell (54), whereby a heating medium passes between the termoelectric modules (5) and turbulators (55). The lower shell (53), upper shell (54) and turbulators (55) are formed out of a transparent material so that the interior of the heat exchanger units can be visually observed.
