CO OZNACZA SŁOWO HEAT SINK
Zlewozmywak
W systemach elektronicznych radiator jest pasywnym wymiennikiem ciepła, który chłodzi urządzenie przez rozproszenie ciepła w otaczającym medium. W komputerach, radiatory są wykorzystywane do chłodzenia centralnych jednostek przetwarzania lub procesorów graficznych. Zlewozmywaki ciepła są stosowane z urządzeniami półprzewodnikowymi wysokiej mocy, takimi jak tranzystory mocy i optoelektronika, takie jak lasery i diody emitujące światło, gdzie zdolność rozpraszania ciepła podstawowego urządzenia jest niewystarczająca do umiarkowania jego temperatury. Radiator ma na celu zmaksymalizowanie powierzchni w kontakcie z otoczeniem chłodzącym, takim jak powietrze. Prędkość powietrza, wybór materiału, konstrukcja wypukłości i obróbka powierzchni są czynnikami wpływającymi na wydajność radiatora. Metody mocowania radiatora i termoizolacyjne materiały wpływają również na temperaturę matrycy układu scalonego. Kleje termiczne lub smar termiczny poprawiają wydajność radiatora przez napełnianie szczelin powietrznych pomiędzy radiatorem a urządzeniem.
Definicja słowa heat sink w słowniku
Definicja radiatora w słowniku to metalowa płytka zaprojektowana specjalnie do przewodzenia ciepła z elementu elektrycznego. Inną definicją radiatora jest warstwa materiału umieszczona w zewnętrznej powłoce szybkich samolotów w celu pochłonięcia ciepła.
