Example of circulating fluid piping
Figure 2
The thermo-con is constructed as shown in Figure 1. It
interposes a Peltier device (thermo-module) between the
heat exchangers for the circulating fl uid and facility water
and controls the DC power supply to achieve the target
outlet temperature of circulating fl uid precisely.
The circulating fl uid returns to the tank, and is transferred
by the pump which is built in the thermo-con, and goes
through the heat exchangers and temperature sensor and
out from the circulating fl uid outlet.
Figure 2 shows an example of circulating fl uid piping. The
circulating fl uid is transferred at a constant temperature
by the pump.

Construction and Principles
Principle of Peltier Device (Thermo-module)
A Peltier device (thermo-module) is a plate
type element, inside which P-type semicon-
ductors and N-type semiconductors are lo-
cated alternately. If direct current is supplied
to the Peltier device (thermo-module), heat is
transferred inside the device, and one face
generates heat and increases temperature
while the other face absorbs heat and de-
creases temperature. Therefore, changing
the direction of the current supplied to the
Peltier device (thermo-module) can achieve
heating and cooling operation. This method
has a fast response and can shift quickly be-
tween heating and cooling, so temperature
can be controlled very precisely.
