Measurement of Heat Fluxes in a Laboratory Model of a Thermoelectric Refrigerator

The article presents a method for measuring and calculating heat fluxes in a laboratory model of a thermoelectric refrigerator. Using the developed methodology, studies of the main cooling characteristics in a wide range of temperature conditions and power supply parameters of the thermoelectric module were carried out. As a result of the research, the values of heat fluxes and thermal resistances of the thermally insulated body of a thermoelectric refrigerator, heat supply and removal devices were determined. From the measurement data, the load characteristics of the thermoelectric module are obtained at different values of the current strength and temperature of its hot side.
