Purpose The purpose of this study is to investigate the validation of the usefulness of cooling systems containing Peltier modules for cooling power devices based on measurements of the influence of selected factors on the value of thermal resistance of such a cooling system. Design/methodology/approach A cooling system containing a heat-sink, a Peltier module and a fan was built by the authors and the measurements of temperatures and thermal resistance in various supply conditions of the Peltier module and the fan were carried out and discussed. Findings Conclusions from the research carried out answer the question if the use of Peltier modules in active cooling systems provides any benefits comparing with cooling systems containing just passive heat-sinks or conventional active heat-sinks constructed of a heat-sink and a fan. Research limitations/implications The research carried out is the preliminary stage to asses if a compact thermal model of the investigated cooling system can be formulated. Originality/value In the paper, the original results of measurements and calculations of parameters of a cooling system containing a Peltier module and an active heat-sink are presented and discussed. An influence of power dissipated in the components of the cooling system on its efficiency is investigated.

Recent advances in pump lasers have led to their use in a wide variety of medical, industrial, defense, and space applications.Examples include dense wavelength division multiplexing (DWDM) and long haul fiber optic telecommunications. Given the wide ambient temperature ranges over which these devices are required to operate, their success depends on good thermal management. Specifically, to minimize dynamic changes in wavelength and power output, the lasing element's temperature must be accurately stabilized. This requirement has led to the application of thermoelectric coolers (TEC's) to control laser diode temperature. In this work, all aspects of a pump laser's thermal management, including nonlinear control electronics, thermal analysis of the opticalmechanical design, and thermoelectric modeling are integrated within a single analog simulator. This simulator provides an accurate steady state and transient model of the full closed loop system. Also included is an example of how this modeling was successfully reduced to practice.

“…The first models of the thermoelectric modules that were implemented into electronic circuits' simulators were working in cooling mode. In [53], an analysis of a developed PSPICE-compatible equivalent circuit of a thermoelectric cooler was demonstrated, whereas in [54,55], an electrothermal macromodel of an active heat sink based on TEM for cooling process simulation was described. In [56], a modified electrothermal model of TEMs was demonstrated, with temperature-dependent material properties taken into consideration.…”

This paper deals with an electrothermal model of a thermoelectric converter dedicated to performing simulations of coupled thermal and electrical phenomena taking place in harvesting processes. The proposed model is used to estimate the electrical energy gain from waste heat that would be sufficient to supply electronic circuits, in particular autonomous battery-less nodes of wireless sensor networks (WSN) and Internet of Things (IoT) devices. The developed model is not limited to low-power electronic solutions such as WSN or IoT; it can also be scaled up and applied to simulations of considerably higher thermal power conversion. In this paper, a few practical case studies are presented that show the feasibility and suitability of the proposed model for complex simultaneous simulation processes in both the electrical and thermal domains. The first example deals with a combined simulation of the electrothermal model of a thermoelectric generator (TEG) and an electronic harvester circuit based on Analog Devices’ power management integrated circuit LTC3108. The second example relates to the thermalization effect in heat sink-less harvesting applications that could be mitigated by a pulse mode operation. The unique contribution and advancement of the model is the hierarchical structure for scaling up and down, incorporating the complexity of the Seebeck effect, the Joule effect, heat conduction, as well as the temperature dependence of the used materials and the thermoelectric pellet geometries. The simulations can be performed in steady as well as transient states under changing electrical loads and temperatures.
