Thermal investigations of PCM enhanced electronics cooling

Felczak Mariusz, Więcek Bogusław

Measurement Automation Monitoring

2019

Vol. 65, No. 2

44--47

The paper presents experimental results of PCM (Phase Change Material) enhanced cooling system. The investigations were focused on obtaining the best results of the cooling system during its start-up. The latent heat of phase change material was used to decrease temperature of the cooled electronic device. Comparison of a standard heat sink available on the market and the same heat sink filled with PCM applications was done. Temperature was monitored and registered during device start-up until its thermal steady state. It was done using contact and IR temperature measurement methods. PCMs usage enabled to absorb heat during electronic device start-up. The paper proves that using PCMs it is possible to delay temperature rise during electronic devices heating.
