Helix angle and helix rise angle of spiral baffle heat exchanger
Thread Content
I am not in the design or process department, and I have only seen pictures of tube bundles of spiral baffle heat exchangers. Please tell me, who is the angle between the spiral angle and whom? Is it the same thing as helix angle? If described in English, are spiral angle and ascending angle correct? This post was last edited by pllhy on 2009-3-27 14:31 ]
Helix angle in machinery: On a pitch cylindrical surface, the angle between the tangent of the helix and the vertical plane of the thread axis. Helix angle: On the pitch diameter cylinder, the angle between the tangent of the helix and the thread axis. The helix angle in the spiral baffle should be the helix angle in machinery: helix angle
As the spiral angle of the spiral baffle heat exchanger increases, the shell side heat transfer coefficient of the spiral baffle heat exchanger increases. The spiral angle is generally 12°, 18°, 30°, and 40°.
