bakarna plocica (cist bakar, za primer) 40x60mm 5mm debljine
na njoj su 4 bakarne plocice 12x5mm 1mm debljine (kao deo samog bakra, znaci izmedju njih i samog hladnjaka je termalni otpor nula, tj samo thermal conductivity samog bakra)

na povrsinu (ovu vidljivu) ovih malih "pedova" u svaki ped "guramo" 30W
temperatura spoljne sredine je 298K
konvekcija vazduha je 10W /m<sup>2</sup>K
