Enhanced heat management via auger in a pipe

Abstract

Herein discussed is a heat management system comprising a pipe and a static auger inside the pipe, wherein the pipe has an inner diameter of d, wherein the auger has an outer diameter D and a pitch P, wherein the ratio of D/P is no less than 1, and wherein the auger outer diameter D is no less than 90% of the pipe inner diameter d. In an embodiment, the ratio of D/P is in the range of 2-10, or 2-5, or 2-4, or 5-10. In an embodiment, the pipe is made from stainless steel, carbon steel, Monel, Inconel, Incoloy, Hastelloy, ceramics, silicon carbide, alumina, and combinations thereof. In an embodiment, the system comprises a fluid passing through the pipe, wherein the pipe heats or cools the fluid.
