Document Type and Number:
Japanese Patent JP2015169345
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid film formation member capable of flowing down fluid by forming an even liquid film along the inner wall of a fluid flow-down pipe arranged in a vertical direction, and a liquid film type heat exchanger mounted with the liquid film formation member.SOLUTION: A liquid film formation member 7 is mounted in the upper end openings of a plurality of fluid flow-down pipes 6 in which axial lines are arranged toward a vertical direction, and is formed into a cylindrical or columnar shape. On the outer peripheral surface of the liquid film formation member 7, a plurality of support parts 9 projecting in a direction orthogonal to the axial line from the outer peripheral surface and fitted into the inner wall of the fluid flow-down pipe 6 is formed with intervals in a circumferential direction. Between the support parts 9, a flow passage formation recess part 8 opened at both ends in the direction orthogonal to the axial line and an axial direction is formed.
