This study presents a new approach that uses a genetic algorithm (GA) to optimize the arrangement of two-stage thermoelectric coolers (TECs). Three practical configurations of two-stage TECs, 1) with two stages electrically connected in series, 2) with two stages electrically separated from each other and 3) with two stages electrically connected in(More)
This study presents a new approach using genetic algorithms (GAs) to optimize the arrangement of two-stage thermoelectric coolers (TECs). Focusing on the two-cascade TECs, parameters, the applied electrical current and the number of thermocouples in each stage, were optimized to yield the maximum cooling capacity and the maximum coefficient of performance(More)
Thermoelectric heat pumps (TEHPs) have been applied to many electronic devices to create a steady, low-temperature operating environment. The cooling capacity is the critical issue in the application consideration. This study uses a hybrid genetic algorithm (hGA) to maximize the cooling capacity of a two-stage TEHP under the condition that the amount of(More)
This paper describes a quick thermal test method and an innovative mechanism that have been developed for measuring the thermal resistance of coolers and thermal modules. The test method basically relies on accurate measurement of the differential temperature of coolers/thermal modules at each time step. A theoretical analysis was also carried out in order(More)
