Abstract


We have investigated the influence of structural and technological elements on the basic parameters, reliability indicators, and the dynamics of operation of thermoelectric cooling devices under various current modes within the operating range of temperature differences. We analyzed the ratios of correlation between the time required to enter a stationary mode and relative intensity of failures in a cooler, and energy indicators, thermoelectric parameters of thermoelements, structural and technological indicators.

An analysis of the time required to enter a stationary mode was performed for different modes of operation from the maximum cooling capacity to the minimum failure rate. It is shown that in order to reduce the time required for a cooler to enter a stationary mode, at the predefined geometry of thermoelements and temperature difference, it is necessary to employ the mode of maximum cooling capacity.

The quantitative analysis showed that at the predefined geometry of thermoelements branches the time required to enter a stationary working mode does not depend on the number of thermoelements in a thermoelectric cooler. At a difference of temperatures close to the maximum value, the time required to enter a stationary working mode differs slightly for all modes of operation. Comparative analysis of the basic parameters of reliability indicators and dynamical characteristics makes it possible to find compromise solutions when constructing thermoelectric devices taking into consideration the weight of each of the constraints.

From a practical point of view, the results obtained suggest that increasing the cooling rate does not require changes to the existing technology for making thermoelectric coolers. Control over performance speed during transition from one stationary state to another state is executed through the selection of current modes in the operation of a thermoelectric device. In this case, there is a possibility to choose the conditions under which reliability indicators match the permissible limit.
