摘要：PURPOSE:To make it possible to supply uniformly medium liquid over the whole

surface of a heat transfer pipe by fixing and holding to pipe plates a liquid dispersing tray

the multiple hole plate of which has the row of its holes provided in it positioned right

above each heat transfer pipe of a bundles of heat transfer pipes.

CONSTITUTION:Between pipe plates 6a and 6b in a shell 9 a liquid dispersing tray 5 is

fixed and held by inserting a support metal member 8 into a through-hole 7 provided in

each pipe plate and welding the metal member 8 to the pipe plate in such a fashion that

the row 4 of holes provided in a multiple hole plate 3 is positioned right above each heat

transfer pipe 2. A medium F which flows into the liquid dispersing tray 5 through a liquid

inlet 12 is supplied uniformly from a row of holes 4 to each heat transfer pipe 2 which is

positioned right below the row of holes 4 to form a uniform down-flowing liquid film and

this liquid film exchanges heat with a heating fluid A flowing in the heat transfer pipe 2.

The vapor F' of the medium liquid exits from a vapor outlet 15 and vapor liquid F the

could not be vaporized flows out from a liquid outlet 16. With this constitution a dried

section on the heat transfer pipe is eliminated, providing a horizontal pipe outside down-

flow liquid film type evaporator of a small size and high reliability with high efficiency.
