Abstract
Development of a numerical heat transfer model via steady-state thermal-electric FEM solver for transport and storage of biological material, vaccines among others based on the Peltier effect. Biological materials require specific temperatures for their storage. Currently, the most used method is through a box made of expanded polystyrene, containing reusable dry ice in the form of tubes/plates (or just ice), which can have temperature changes while transportation, damaging the materials (organs, medications, vaccines, etc.) since there is no adequate temperature control. The only existing control (which is not really a control) is the insertion of a thermocouple to verify the internal temperature of the box. Despite the advantages of using peltier cells as an organ preservation system, numerical studies are needed to prove their effectiveness in applications such as organ conditioning. As one of the difficulties encountered is related to the heat transfer process within the box as well as the type of material to be used due to its thermal conductivity and the type of heat exchanger that allows the dissipation of heat from the hot face of the thermoelectric cell. Therefore, this work aims to develop a numerical model using the FEM technique and the Ansys steady-state thermal electric tool as a computational platform as a reference base for the operating conditions for the storage of biological material, vaccines, medications, among others, the simulation look forward to verify if the thermoelectric cell (at first moment without any material in his cold surface and after with a aluminum plate coupled) will be able to reach the temperature of 4ºC to 9ºC according to the temperature values for transporting organs defined by the National Heat Surveillance Agency (ANVISA). It’s expected that the numerical results will establish the initial parameters for the construction of an experimental prototype based on peltier effect.
