CONTROLLING METHOD FOR THERMOELECTRIC COOLING DEVICE AND HEAT-DISSIPATING MODULE EMPLOYING SAME

摘要

A controlling method for a thermoelectric cooling device is provided. The thermoelectric cooling device has a cold side and a hot side. After the thermoelectric cooling device is enabled, a temperature of the cold side and an ambient temperature around the thermoelectric cooling device are acquired. By judging whether the ambient temperature is higher than or equal to a preset reference temperature, an initial value of a duty cycle corresponding to an electric energy to be received by the thermoelectric cooling device is set. Then, a judging step is performed to judge whether the temperature of the cold side is higher than or equal to the ambient temperature. If the judging condition is satisfied, the duty cycle is increased by a specified percentage. If the judging condition is not satisfied and the duty cycle is higher than 0%, the duty cycle is decreased by the specified percentage.

1. A controlling method for a thermoelectric cooling device, the thermoelectric cooling device having a cold side and a hot side, the method comprising steps of:
(a) enabling the thermoelectric cooling device, and acquiring a temperature of the cold side and an ambient temperature around the thermoelectric cooling device; (b) judging whether the ambient temperature is higher than or equal to a preset reference temperature; (c) setting an initial value of a duty cycle corresponding to an electric energy to be received by the thermoelectric cooling device according to a judging result of the step (b); (d) judging whether the temperature of the cold side is higher than or equal to the ambient temperature; (e) if the judging condition of the step (d) is satisfied, increasing the duty cycle by a specified percentage, and repeatedly performing the step (d); and (f) if the judging condition of the step (d) is not satisfied, decreasing the duty cycle by the specified percentage and repeatedly performing the step (d) by judging whether the duty cycle is higher than 0%.
