Implementation of an external intelligent cooling system for laptops using TECs

Abstract

Laptop coolers are external devices, which are ancillaries to the existing cooling mechanism of laptops, in order to reduce their internal temperature. Available coolers do not provide efficient cooling in high ambient temperatures. This paper presents the implementation of an intelligent laptop cooler, which can vary its performance according to the laptop temperature and ambient temperature, and actively cool the air flow by using thermoelectric coolers (TECs). In this work, a dynamic air flow is intelligently cooled by the device and the process will be controlled, based on the feedback provided by a temperature sensor placed at exhaust vent of laptop. Further, the device is designed to reduce dust content in the air flow which passes through the laptop. Ultimately an effective cooling is provided to the laptop through this device while increasing the lifetime of the laptop.
