Elektronik sürücü devreleri ultrasonik transdüser sistemlerinin sürülmesinde kullanılır. Yüksek frekans nedeniyle, termal yönetim sürücünün güvenilirliğini önemli ölçüde etkileyen ana sorundur. Bu tür aşırı ısınma problemlerini çözmek için farklı uygulamalar üzerinde çalışılmaktadır. Bu çalışmada, push-pull sürücü devresindeki fazla ısıyı dağıtmak ve sistem performansını artırmak için bir termoelektrik kendinden soğutma sistemi tasarlanmıştır. Termoelektrik kendinden soğutma (TSC), herhangi bir ısı üreten cihazın elektrik tüketimi olmadan soğutulmasını sağlayan yeni bir termoelektrik uygulamadır. Bu makale, bir TSC sisteminin deneysel analizini sunmaktadır. Deneysel bir kurulum 275W push-pull ultrasonik sürücü devresinde tasarlanmıştır. Bu çalışmada, termoelektrik sistemin performansının farklı kalınlıklarda soğuk genişletici kullanımıyla nasıl değiştiği gösterilmiştir. 5 ve 10 mm kalınlığındaki soğuk genişleticiler, kendi kendini soğutma sisteminin hem sıcak hem de soğuk yüzeylerinin soğutma performansı üzerinde olumlu bir etkiye sahiptir. Bununla birlikte, soğuk genişleticinin kalınlığı eşik değeri geçtiğinde, soğuk genişleticinin ısı kapasitesi, soğuk ve sıcak yüzeyler arasındaki sıcaklığın fanın çalışmasını sağlayan kritik sıcaklık farklarına ulaşmasını engellemiştir.

Experimental Investigation of Thermoelectric Self-Cooling System for the Cooling of Ultrasonic Transducer Drivers

Electronic driver circuits are used for the driving of ultrasonic transducer systems. Due to the high frequency switching, thermal management is the main problem that has a significant effect on the reliability of the driver. Different applications are being studied to solve such overheating problems. In this study, the designed thermoelectric self-cooling system dissipates the excess heat generated in the push-pull drive circuit and improves system performance. Thermoelectric self-cooling (TSC) is a new thermoelectric application which provide the cooling of any heat-generating device without electricity consumption. This paper presents the experimental analysis of a TSC system. An experimental setup is designed on a 275W push-pull ultrasonic driver circuit. In this study, it has been shown how the performance of the thermoelectric system changes with the use of cold extender of different thicknesses. 5 and 10 mm thickness cold extenders have had a positive effect on the cooling performance of both the hot and cold surfaces of the self-cooling system. However, when the thickness of the cold extender is increased beyond the threshold, the heat capacity of the cold extender has prevented the temperature between the cold and hot surfaces to reach critical temperature differences which enables the fan to operate.
