Abstract

Tema ovoga rada je zagrijavanje zraka u dva serijski spojena lamelna izmjenjivača topline te njihov termodinamički proračun.

U prvom poglavlju ovoga rada govori se općenito o izmjenjivačima topline te njihovoj širokoj primjeni u raznim granama industrije. Osim toga dan je i uvid u osnovni princip rada takvih aparata.

Nakon toga se u drugom poglavlju govori o određenoj vrsti izmjenjivača topline a to su lamelni izmjenjivači. Opisan je njihov princip rada, od kojih elemenata se sastoje, vrste njihovih izvedbi i njihove prednosti i mane.

U trećem poglavlju je opisana sama problematika zadatka i veličine koje je potrebno izračunati u sklopu rada.

Konstrukcijski proračun je obrađen u četvrtom poglavlju dok je u petom poglavlju obrađen termodinamički proračun lamelnih izmjenjivača topline.

U šestom poglavlju je donesen zaključak i osvrt na rad.

Abstract (english)

The topic of this thesis is process of air heating in two serial arranged finned heat exchangers and their thermodynamic calculus.

In first chapter of this thesis it is spoken about heat exchangers in generally and their applications in various branches of industry. Also it is given a fundamental insight in their working characteristics.

Second chapter describes specific kind of heat exchangers, that are finned heat exchangers. Their working characteristics, design elements and various designs are thoroughly described.

Task goals an it's content are described in third chapter.

Design calculus is elaborated in fourth chapter while thermodynamic calculus is elaborated in fifth.

Conclusion and review of this thesis are given in sixth chapter.
