Języki publikacji
Abstrakty
W artykule przedstawiono projekt tunelu powietrznego do badań chłodzenia konwekcyjnego układów elektronicznych. Projekt został zweryfikowany poprzez symulacje numeryczne wykonane za pomocą programu FLUENT. W dalszej części pracy przedstawiono metodą laserowego noża świetlnego. Wykorzystuje sieją do pomiaru prędkości przepływu powietrza w tunelu, który to pomiar jest niezbędny do wyznaczenia warunków chłodzenia. W ostatniej części pracy przedstawiony jest przykład zastosowania tunelu do badań odprowadzania ciepła w elektronice. Opisano i zbadano efekt śladu termicznego podczas chłodzenia konwekcyjnego układów elektronicznych.
The article presents design of a low-speed wind tunnel for forced convective cooling investigations of electronic devices. Design method of the tunel is presented. Results are verified by numerical simulations completed with the Fluent software. Particle image velocimetry method (PIV) as one of the method proposed for air velocity measurements is presented. Velocity measurements during wind tunnel investigations are necessary to know electronic devices cooling conditions. In the last section of the article, an example of electronic cooling investigations for the designed wind tunnel, is presented. It illustates the importance of thermal wake effect during heat dissipation in electronics.
