Dissipadores de calor aletados e aplicações na indústria de alimentos: revisão de literatura e simulação de modelos comumente utilizados

Abstract

Heat sinks are metal objects of extended surfaces capable of maximizing the heat exchange in a process and / or equipment through conduction, convection and thermal radiation. There are different conformations for heat sinks which are defined according to the desired efficiency in the design to be applied. Heat sinks are of great importance in the food industry for process control as a means of improving their efficiency through energy saving, favoring technological aspects and perfecting processes. The present work deals with the methodology used to construct the literature review of different types of heat sinks used in thermal processes of the food industry, the definitions of heat transfer, the equations necessary for the study and analyzes of its efficiency and the result of some computational simulations of heat transfer in these devices using the finite volume method.
