THERMAL CONTACT RESISTANCE MATCHING TO OPTIMIZE …

Our results indicate that the optimal output power and conversion efficiency of TEGs can be reached when the TCR at the interfaces of the p-type thermoelement is equal to its counterpart at the interfaces of the n-type thermoelement. Furthermore, optimization of TEG performance by matching the TCR becomes much more obvious when the total TCR is smaller. We then applied our model to the TEG with

Modeling of Non-Uniform Thermoelement Devices Subject to Lateral …

The significance of lateral heat convection arises from a new application, in which thermoelements form the walls of a MEMS-based convergent-divergent micronozzle in order to pump heat from the divergent part of the micronozzle to the convergent part to enhance overall performance. To assess the effect of thermoelement, we develop a quasi-one-dimensional model for thermoelements, in which, the …
