Abstract
<p>We examined a dynamic model of the relationship between basic parameters and indicators of reliability, taking into consideration the structural and technological elements, for a single-stage cooling device under various current modes of operation, thermal load at a temperature difference of 40 K. The ratios derived allow us to define the time required for a single-stage of thermoelectric cooling device to enter a stationary mode of operation, and the temperature of a heat-absorbing junction. The dependences take into consideration values of a thermal load, the number of thermoelements, current mode of operation, with respect to both the mass and heat capacity of the object, and the mass and heat capacity of structural and technological elements at heat-absorbing junctions of the module. It was found that the heat capacity and mass of structural and technological elements of the module affect not only the time required to enter a stationary mode, but the device's reliability indicators, reducing them by 2‒3 times. The results of analysis of dynamic characteristics and energy indicators of a single-stage thermoelectric cooler demonstrated the possibility to control the time required to enter a stationary mode. Structural control, enabled by selecting the number and geometry of the cooler's thermoelements, and the mass and heat capacity of the load, makes it possible to reduce the time required for a thermoelectric cooling device to enter a stationary mode by up to 2.5 times. Operational control, executed by changing working current of the cooler, makes it possible to reduce the time required to enter a stationary mode by up to 3 times.</p>
