Heat transfer analysis of scraped surface heat exchanger

Abstract

Abstract. The main structure and the production theory of scraped surface heat exchanger was introduced. The heat transfer mechanism of heat exchanger is analyzed, and the mathematical model of heat transfer is established in this paper. There had three mode of heat transfer in Scraped surface heat exchanger. They were External heat transfer, Internal heat transfer ,Convection heat transfer, respectively, the mathematical model corresponding to them were established. On this basis, production equipment line with scraper heat exchanger as the core machine was improved.
