Abstract
Mala računala (klase Arduino), poznatija kao Single-Board Computers (SBC), imaju široku primjenu u industriji, a najčešće se koriste kao ugrađene upravljačke jedinice. Zbog svojih malih dimenzija, uglavnom se ugrađuju u uređaje sa limitiranim prostorom. Kako sva dovedena električna energija unutar računala disipira u toplinu, za optimalno funkcioniranje računala, posebice u tako skučenim uvjetima, potrebno je osigurati dostatno hlađenje komponenti uz minimalni utrošak energije. U ovom radu se uz pomoć računalne dinamike fluida provela simulacija hlađenja modela Raspberry PI prirodnom konvekcijom. Cilj simulacije je ispitati efikasnost hlađenja putem slobodne konvekcije, te stvoriti podlogu za validaciju daljnjih simulacija hlađenja. Također, provedeno je ispitivanje neovisnosti geometrijske mreže s ciljem kreiranja pouzdane geometrijske mreže koja bi bila pogodna za te daljnje simulacije. Geometrijska mreža načinjena je pomoću komercijalnog programskog paketa CF-MESH+. Sva generirana toplina koncentrirana je u dvije komponente računala za koje je dokazano da se najviše zagrijavaju, a strujanje fluida ostvareno je u zatvorenoj domeni sa stijenkama konstantne temperature. Proračun je proveden pomoću programskog paketa OpenFOAM
Abstract (english)
Small computers (Arduino class), known as Single-Board Computers (SBC), are widely used in industry and are very often used as embedded control units. Due to their small dimensions, they are mainly installed in devices with limited space. As all the supplied electrical energy dissipates into heat inside the computer, for the optimal functioning of the computer it is necessary to ensure sufficient cooling of the components with minimal energy consumption, especially in such cramped conditions In this thesis, a computational fluid dynamics simulation of the cooling of the Raspberry PI model by natural convection was carried out. The goal of the simulation is to test the efficiency of cooling through free convection and to create a basis for validating further cooling simulations. Also, mesh independence test was carried out with the aim of creating a reliable geometric mesh that would be suitable for further simulations. The geometric mesh was created using the commercial software package CF-MESH+. All generated heat is concentrated in two computer components that have been proven to heat up the most. Fluid flow is realized in a closed domain with constant temperature walls. The calculation was performed using OpenFOAM software package.
