ABSTRACT:
A heat exchanger for efficient transfer of sensible heat between a highly viscous fluid and a secondary fluid. This exchanger has an annular passage formed between an inner cylinder and outer cylinder. The highly viscous fluid passes through the annular passage while the secondary fluid passes both inside the inner cylinder and outside of the outer cylinder making both cylinders heat transfer surfaces. A scraper mechanism rotates within the annular passage which scrapes both heat transfer surfaces. The scraper mechanism driven by the pressure exerted by the fluid to be cooled. This scraping action serves to both continually clean the surfaces and to enhance the heat transfer efficiency.
