SIMULASI 3 DIMENSI DISTRIBUSI PANAS PLAT KNALPOT MOBIL UNTUK ELEMEN TERMOELEKTRIK
Abstract: This study simulates
the distribution of heat in the conductor plate micro energy generation based
module Thermoelectric Generator (TEG) type 40-40-10 / 100 to optimize the
absorption of heat from the vehicle exhaust waste heat. The module has a
maximum operating temperature of 423K. The modeling is done using MATLAB with a
modified diffusion equation by application of 900K of temperature as boundary
condition on the surface of the base plate which is in contact with the heat
source. The plate with aluminum material modeled in varies form of solid,
hollow, hollow gitter, hollow heatsink, with dimensions of 110mm long, 60mm
wide, 30mm thick base and 30mm thick bulge. The best temperature drop obtained
for ΔT = 178,67K (19.85%) produced by the shape of a hollow heatsink plate. The
resulting temperature of this model is then lowered back with varying types of
material such as aluminum, copper, iron, and stainless steel, as well as by
varying the number of TEG array that is 1 to 4-arrays, each array consisting of
two modules. Drop in temperature that comes closest to the maximum TEG
operating temperature is a drop in temperature that generates the final
temperature of 402K, which comes from hollow-with-heatsink stainless steel
plate with 50mm of thick and 4-arrays formation.
