Combined heat exchanger module

A combined heat exchanger module comprising:

• a first upper tank configured for introducing a cooling water into the combined heat exchanger module;
• a lower tank into configured for introducing the cooling water into the combined heat exchanger module or for discharging the cooling water from the combined heat exchanger module;
• a second upper tank configured for discharging the cooling water from the combined heat exchanger module;
• first heat radiating channels, each having an upper end connected with the first upper tank and a lower end connected with the lower tank, the first heat radiating channels being formed with a plate tube shape through which the cooling water flows and being arranged in planes which are parallel to the direction of air flow;
• second heat radiating channels, each having a lower end connected with the lower tank and an upper end connected with the second upper tank, the second heat radiating channels being formed with a plate tube shape through which the cooling water flows and being arranged in planes which are parallel to the direction of the air flow and are disposed upstream or downstream of the first heat radiating channels with respect to the direction of the air flow;
• and
• a plurality of thermoelectric elements, each having a first surface which is in surface contact with the second heat radiating channels and a second surface exposed to air,
• wherein the plurality of thermoelectric elements are arranged in series along a direction parallel to a straight line connecting the upper tank and the lower tank, and are connected to each other.
