- Definition(s)
- A heat sink is a metal base or plate onto which one or more components are mounted to absorb, carry away, or radiate the heat generated by the component(s). Heat sinks are generally made of an aluminum alloy and often have fins. All computers require a heat sink. Some also require a fan. A heat sink without a fan is called a passive heat sink; a heat sink with a fan is called an active heat sink. Network Dictionary
- Example sentence(s)
- The heat sink is secured to a printed circuit board with at least one heat generating component through the fixing portion of the base. The heat sink is improved by forming one or more slots at lateral sides of the base such that one or more deformable portions can be defined on the base. - Free Patents Online
by - Heatsinks must be designed in a way that air can easily and quickly float through the cooler, and reach all cooling fins. Especially heatsinks having a very large amount of fine fins, with small distances between the fins may not allow good air flow. A compromise between high surface (many fins with small gaps between them) and good aerodynamics must be found. - The Heatsink Guide
by - If your chip surpasses a certain temperature, it will fail and cease to operate. Finding a heat sink will be vital to keeping the chip humming and performing as it was meant to. - eHow.com

- Definition(s)
- Теплоотвод - металлическое основание, служащее для отвода тепла от различных компонентов. Обычно имеет ребра для более эффективного отвода тепла. Часто на них ставится вентилятор для еще более активного отвода тепла. Такой теплоотвод называется активным, а без вентилятора - пассивным.

- Если на вашей видеокарте сгорел кулер, то VGA5314 будет неплохой заменой. Возможность работать при 5В может быть ценным качеством: даже в этом режиме VGA5314 будет работать лучше, чем пассивный теплоотвод на северном мосту, а вентилятор на такой скорости будет работать практически вечно. - 3DNews
by Igor Savenkov - Dual Cooling - система включает в себя активный теплоотвод модуля DPVRM и активный теплоотвод для микросхемы "северного моста" чипсета. - Overclockers
by Igor Savenkov - Многие современные процессоры во время работы разогреваются так, что обычный пассивный теплоотвод не может их охладить. - Электроник

- Definition(s)
- Dissipador de calor é o nome dado a um objeto de metal sendo geralmente feito de cobre ou alumínio, que pelo fenômeno da condução térmica e uma maior área por onde um fluxo térmico pode se difundir, maximiza o nível de dissipação térmica de qualquer superfície que gere calor. Wikipedia - by Hugo Lopes (X)
- Example sentence(s)
- O material de interface térmica, que é colocado entre o processador e o dissipador de calor, atua como uma conexão térmica para assegurar a boa transferência de calor. - Intel

- Definition(s)
- Hladnjak je uređaj koji upija i odaje toplotu koju stvara električna komponenta, kao što je integrisano kolo, sa ciljem sprečavanja pregrevanja. Obično je napravljen od metala i često ima krilca koja doprinose prenošenju toplote u atmosferu Own research - by Milan Djukić
- Example sentence(s)
- Hladnjak
Kako bi se iskoristilo što više od limitirane površine, hladnjak pokriva celokupnu gornju površinu pojačala. Proizveden je od bloka aluminijuma težine 10 Kg. a posle završne obrade njegova težina reducirana je na samo 3.5 Kg.!
- BM
by Milan Djukić - Postoji nekoliko sistema hlađenja od kojih je ubedljivo najpopularnija kombinacija hladnjaka i ventilatora, „Heat Sink Fan”. Kod nas se to najčešće naziva „kuler”. Naziv jeste pomalo ružan, međutim, daleko je ispravniji nego samo „hladnjak” ili „ventilator”, jer se kuler sastoji od oba ta dela.

Da bi dobro odvodio disipiranu toplotu (opet, pogrešno je reći hladiti jer to nije ono što HSF radi) potrebno je i da hladnjak i ventilator budu „na visini zadatka”. Kako je hladnjak taj koji naleže direktno na jezgro procesora bitno je da je osnova od što kvalitetnijeg materijala koji dobro „prima” toplotu, u praksi to se svodi na izbor neke legure aluminijuma ili bakra.

by Milan Djukić - Još jedan od aspekata na koji treba obratiti naročitu pažnju odnosi se na karakteristike postojećeg ventilatora (cooling fan) i hladnjaka (heat sink). - eKnjižara

- Definition(s)
- In elettronica un dissipatore è un dispositivo che consente l'abbassamento di temperatura di componenti che sprigionano calore come i Transistor o i processori, evitando che il surriscaldamento degli stessi ne provochi il malfunzionamento, l'arresto o la rottura.
I materiali utilizzati sono il rame e l'alluminio; il primo viene impiegato nei casi dove occorra la massima efficienza nel trasferimento termico, accettandone il maggior costo e il maggior peso specifico, l'alluminio viene scelto per condizioni operative meno impegnative. Wikipedia - by Simona Corsellini
- Example sentence(s)
- I dissipatori possono essere di tre tipi:
ATTIVI: Componenti che agiscono sui flussi d'aria favorendone il ricambio (le ventole).
PASSIVI: Materiali termoconduttivi con proprietà di dissipazione (il case stesso).
MISTI: Compnenti più complessi costituiti dall'unione dei due tipi precedenti. - Tecnok
by Simona Corsellini - Anche i portatili, visti i ridotti spazi e le forme dei dissipatori con lamelle molto sottili e ravvicinate per ottimizzare lo scambio termico in poco spazio, soffrono molto di questo problema spesso sottovalutato - M.A. Elettronica
by Simona Corsellini - Quasi tutti i computer moderni escono dalla fabbrica con installati ventole e dissipatori certificati dal costruttore, quindi adeguati alle esigenze di ventilazione del chip originale, che si prevede viaggerà a una velocità predefinita. - PCWOrld
