Abstract
A dual loop type temperature control module and an electronic device testing apparatus having the same are provided. The temperature control module comprises a first loop through which a first working fluid of a first temperature flows, a second loop through which a second working fluid of a second temperature flows, a controller for controlling a first switching valve such that the first or second working fluid flows through a temperature regulating device, and a second switching valve such that the working fluid flowing through the temperature regulating device returns to the first or second loop. The temperature regulating device adjusts a thermoelectric cooling device to reach two different reference temperatures based on the rise/fall of its temperature dependent on the working fluid. The thermoelectric cooling device regulates the temperature of the tested object under a wide range of temperature difference and with accuracy based on the reference temperatures to facilitate the detection of high/low temperature.
