Construction and Principles
Heat dissipation air fl ow direction
The thermo-con is constructed as shown in Figure 1 . The circulating fl uid outlet temperature
is controlled precisely by a Peltier element (thermo module) between the heat exchanger
and heat sink which is controlled by supplying DC power supply. The circulating fl uid returns
to the tank and is transferred by the pump which is built into the thermo-con, then it goes
through the heat exchangers and temperature sensor and out from the circulating fl uid outlet.
The heat dissipation air fl ow direction is as
shown in Figure 2. Air is taken from the front
of the Thermo-con and discharged from the
rear. Do not cover the inlet and outlet vents.
