Sažetak
Numerical modelling has emerged as a valid alternative to costly thermography measurements used for heat dissipation measurements in electronics applications. A numerical model for conjugate heat transfer was done for the solid and the fluid region. Results were compared with the experimental results which were described in [1]. Modern High powered LED chips range in power between 1 and 21W, whit their low volume and cross-section they are under the influence of significant heat fluxes. These chips have an area of 1mm2 with an average power of 1W, which corresponds to a heat flux of 100 W . This high mm2 localized heat flux can result in a significant reduction of lighting and thermal performance while also shortening the expected operating life of LEDs [2]. In conclusion, simulations of conjugate heat transfer showed that it is possible to use numerical simulations as a cost effective alternative to laboratory measurements.
