Abstract
A heat transfer plate includes a heat transfer area comprising alternately arranged ridges and valleys in relation to a central extension plane of the plate. The ridges form arrows comprising first arrows, which first arrows each comprises two legs arranged on opposite sides of, and a head arranged on, a respective one of a first number of imaginary straight lines extending across the complete heat transfer area parallel to a longitudinal centre axis of the plate. Each imaginary straight line comprises at least one primary portion along which at least three of the first arrow heads are arranged, uniformly spaced. A majority of the imaginary straight lines comprise at least one secondary portion each along which an extension of the ridges and valleys on one side of the imaginary straight line is parallel with the extension of the ridges and valleys on another opposite side of the imaginary straight line.
