I am trying to incorporate a peltier module on a relatively small space. Is there a way to incorporate a 40 x 40 mm heat sink (+- 10mm) to a 40 x 40 mm peltier module in such a way that it can run for more than 10 mins running on 48 Watts whilst removing heat from the peltier module as to maintain a stable cooling temperature? The system also includes a 40 x 40 mm fan.
Are there other passive cooling methods (i.e. usage of coolant) appropriate to further dissipate the heat from the heat sink other than forced convection from a fan?
