I-radiator yensimbi ye-foam yokufudumala ibandakanya umzimba we-radiator kunye nombhobho wokushisa ongaphezulu kwesinye, umbhobho wokufudumala ulungelelaniswe kumzimba we-radiator, kwaye uquka isinyithi se-foam, kwaye i-foam yensimbi ihlelwe kudonga lwangaphandle lombhobho wokushisa. Imodeli yokusetyenziswa ithatha i-foam yesinyithi eludongeni olungaphandle lombhobho wobushushu, okwandisa indawo yokushisa ubushushu bombhobho wobushushu, kwaye inikwe i-capillary grooves kunye nezinto ze-capillary kudonga lwangaphakathi lombhobho wobushushu, ophucula ubushushu. ukusebenza kombhobho wobushushu kwaye kwandisa indawo ethile yendawo yokuqhuba ubushushu. Kukulungele ukuhamba kunye nokushisa ubushushu be-fluid eyandayo ngokuthe ngcembe ngenxa yobushushu, kwaye amandla e-capillary aphuculwe, ukuze umbhobho wobushushu ube nomgangatho ophezulu wokuqhuba ubushushu phantsi kwefuthe elifanayo lokuqhuba ubushushu, ukuze ubushushu bukwazi. idluliselwe kwi-foam yensimbi eludongeni lwangaphandle lombhobho wobushushu ngokukhawuleza nangaphezulu. Kwaye ngenxa yokutshatyalaliswa kobushushu, kuneenzuzo zesakhiwo esilula, indawo enkulu yokutshatyalaliswa kobushushu, isiphumo esihle sokutshatyalaliswa kobushushu, ukusebenza kakuhle kokutshatyalaliswa kobushushu, ukusetyenziswa kwetsimbi encinci kunye nomthamo omncinci.
