Title:
CORRUGATED ROLLER HAVING IMPROVED HEAT TRANSFER EFFECT
Document Type and Number:
WIPO Patent Application WO/2020/149424
Kind Code:
A1
Abstract:
A fluid circulation heating roller, which uses fluid as a heat transfer medium, includes: a roller body having a hollow cylindrical shape; a rotation shaft extending from each of opposite end portions of the roller body and disposed in the same center line; multiple first ducts extending in an axial direction in the roller body so as to heat the outer circumferential portion of the roller body; multiple second ducts extending in the axial direction on the outer circumferential portion of the roller body, wherein the number of second ducts are the same as the number of first ducts; and an insert inserted into at least one of the first or second ducts and extending in the axial direction. According to the present invention, generation of turbulence flow of fluid can be suppressed and laminar flow can be induced, whereby it is possible to maintain fluid movement speed and facilitate vapor circulation and heat transfer.
