Heat exchanger having thermoelectric element

A heat exchanger comprising:

• a heat-generating pack defining therein a circulation space, the heat-generating pack having a passage in an upper portion of one end and a passage in a lower portion of an opposite end of the heat-generating pack;
• a heat-absorbing pack defining therein a circulation space, the heat-absorbing pack having a passage in a lower portion of one end and a passage in an upper portion of and opposite end of the heat-absorbing pack, wherein the heat-generating pack and the heat-absorbing pack are stacked on each other;
• and
• a thermoelectric element disposed between the heat-generating pack and the heat-absorbing pack, the thermoelectric element having a heat-generating surface adjoining the heat-generating pack and a heat-absorbing surface adjoining the heat-absorbing pack.
