碩士 === 國立勤益科技大學 === 冷凍空調系 === 97 === Abstract Thermoelectric cooler/heater has the advantage of being portable, simple, compact, low power consumption, noiseless, reliable, and environmentally benign, it is quite suitable for transporting and storage for bio-medical products (such as blood and platelet) which are very sensitive to temperature variation. In this study, the effort will be focused on the improvement of cooling performance for a thermoelectric blood cooler/heater and a portable storage bag. Performance tests were conducted to investigate the influence of cabinet temperature in the thermoelectric blood cooler. The experimental tests will also be performed to verify the optimized cooling capacity and heating performance, and to quantify the degree of improvement. The thermoelectric blood cooler/heater and storage bag have been developed successfully. The results revealed that it is accessible to cool down to 4℃ for 12V power input and heat up to 37℃ for 3~4V power input for the blood heater/cooler system. Under the temperature perturbation tests for blood storage, the cabinet should be limited under 30 seconds, which is adequate to blood storage.Another blood cooler bag have been developed to maintain 22±2℃ for platelet storage and transportation.It also reveals the feasibility for thermoelectric cooler for blood cold chain system. Furthermore, the application of thermoelectric coolers through patent search has been developed and assessed comprehensively.
