Claim 14:
15. A heat conversion apparatus comprising:
a pipe which includes a first flat surface and a second flat surface disposed to be parallel to the first flat surface and through which air having a temperature lower than a temperature of introduced air is discharged, the pipe including an inlet of the pipe and an outlet of the pipe;
a plurality of thermoelectric elements of which heat-absorbing surfaces are disposed outside of each of the first flat surface and the second flat surface; and
a cooling water passing member disposed on heat-radiating surfaces of the plurality of thermoelectric elements,
wherein at least one of a number and an area of the plurality of thermoelectric elements disposed within a certain distance from the outlet of the pipe is greater than at least one of a number and an area of the plurality of thermoelectric elements disposed within the certain distance from the inlet of the pipe,
wherein:
a heat insulating member is further disposed between the plurality of thermoelectric elements on the first flat surface; and
the heat insulating member is spaced a predetermined distance from at least one printed circuit board (PCB) electrically connected to the plurality of thermoelectric elements on the first flat surface,
wherein an air gap is present between the heat insulating member and the at least one PCB.
