The thermal design
The Peltier element must be contacted on the entire surface on both sides. The cold side is contacted
with the object to be tempered. The object must accommodate the PT1000 sensor. For this purpose,
a hole of Ø3.1mm must be drilled in the body to be tempered. Ideally, this hole should be at least
30mm deep. The temperature is recorded via this sensor. The "hot side" must contact a heat sink
over the entire surface, The heat
sink must be able to dissipate the thermal energy without the “
hot
side” heating up excessively.
The complete structure has to look like in the picture below. It is
irrelevant whether you are cooling with air or another medium.
The surfaces that are contacted with the Peltier element must have good flatness
≤ 0,02mm. For a
good thermal connection, the contact surfaces should also be filled with thermal conductive paste,
thermal oil or thermal conductive foil.
