Abstract: A cold insulation container includes: a cold insulation storage including a coolant vessel; a circulating air fan that causes cold air from the coolant vessel to circulate in the cold insulation storage; a thermoelectric generating module attached to an outer surface of the coolant vessel; and a temperature controller that adjusts a temperature in the cold insulation storage. A temperature difference between the coolant vessel and circulating cold air in the cold insulation storage causes the temperature controller and the circulating air fan to be driven by thermoelectric power generated by the thermoelectric generating module.

Abstract: Provided is a thermoelectric generation module including a plurality of p-type thermoelectric elements 24a and a plurality of n-type thermoelectric elements 24b alternately connected in series and mounted with sandwiched by first and second flexible printed circuit boards 32, 33. The p-type thermoelectric elements and the n-type thermoelectric elements have a chip size of 1 mm or less and 0.2 mm or greater and a height of 0.8 mm or greater and 3 mm or less.

Abstract: A tubular heat exchanger, with a thermoelectric power generation function, includes: a thermoelectric power generation module 2 mounted on an outer circumferential surface of the heat exhaust tube 1; and a cooling pipe 3 mounted on an outer circumferential surface of the thermoelectric power generation module 2. The cooling pipe 3 is for allowing a cooling material to flow therethrough. The thermoelectric power generation module 2 performs thermoelectric power generation by using the outer circumferential surface of the heat exhaust tube 1 as a high-temperature source and using the inner circumferential surface of the cooling pipe 3 as a low-temperature source. The cooling pipe 3 is in tight attachment to the outer circumferential surface of the thermoelectric power generation module 2.
