An internal combustion engine cooling device includes a piston fixedly mounted within a device housing coupled to a plurality of flow paths through which cooling water flows, the piston disposed facing the interior of the device housing; a cylinder container that advances and retreats relative to the piston and has a flange valve that opens and closes a main flow path of the cooling water; a thermal expansion unit provided within the cylinder container that causes the cylinder container to advance and retreat due to volumetric changes attendant upon temperature changes; and a heat-emitting element provided within a piston casing that heats the thermal expansion unit when supplied with electricity. An insulating cover is provided to the exterior of the cylinder container at a portion of the cylinder container disposed facing the cooling water.

Internal combustion engine cooling device

To improve the mass productivity of thermoelectric conversion modules. A thermoelectric conversion moduleis equipped with a pair of substratesand, a plurality of thermoelectric conversion elements, each having one end portion electrically connected to a first electrodewhich is arranged on the substrateand the other end portion electrically connected to a second electrodewhich is arranged on the substrate, and a connection sectionwhich electrically connects the first electrodeelectrically connected to the thermoelectric conversion elementto the second electrodeelectrically connected to an adjacent one of the thermoelectric conversion elements. The connection sectionis separate from at least one of the first electrodeand the second electrode
