A TEC generates heat by Joule effect. This heat comes in addition to the heat generated by the heat source. Therefore, adding a TEC to a model adds heat. If the cooling of the heat sink is insufficient, (not enough convection, for instance), then the TEC will cause the temperature of the heat source to increase. In other words, a TEC lowers the temperature of the heat source only if the heat sink is appropriately ventilated.
Please refer to Solution ID: S-018688 from the SOLIDWORKS Knowledge Base.
Additionally, you may also see Solution ID:S-028696: Could I have an example of the use of a thermoelectric cooler (TEC)?
Unfortunately I do not have access to the SOLIDWORKS Knowledge Base. I'm using the 2016 sp 04 on my work.
Thanks for the explanation. I know how it works. But I have no heating elements. Just a Peltier element and air. Hot side dissipates heat to the housing. The cold side cools the radiator. Therefore, it is too strong heat for such a system.
I can give you my project.
