1. 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 a width of the first flat surface having a certain distance from the outlet of the pipe is greater than a width of the first flat surface having the certain distance from the inlet of the pipe, and a width of the second flat surface having the certain distance from the outlet of the pipe is greater than a width of the second flat surface having the certain distance from the inlet of the pipe,
wherein at least one of a number and an area of the plurality of thermoelectric elements disposed within the 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 cross-sectional area of the outlet of the pipe is greater than a cross-sectional area of the inlet of the pipe,
wherein a heat insulating member is disposed between the plurality of thermoelectric elements on the first flat surface; and
wherein 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.
