Abstract
A heat exchanger comprises a shell having an inlet and an outlet for a first medium, and at least one tube coil disposed in the shell and having straight, substantially parallel coil legs, and an inlet and an outlet for a second medium for exchanging heat with the first medium. Distribution plates with spray holes are disposed in the shell in front of each coil leg at a distance from the center axis thereof which is not more than about 10 times the diameter of the spray holes.

A heat exchanger comprising:
- a shell with an inlet and an outlet for a first medium,
- a plurality of tube coils in said shell,
- adjacent ones of said tube coils being substantially in contact with each other,
- each said tube coil having substantially parallel coil legs and turns adjacent opposite shell walls, and an outlet for a second medium for exchanging heat with said first medium, and
- a plurality of distribution plates,
- each said distribution plate having a plurality of spray holes and a dimension corresponding to the internal cross-sectional area of the shell parallel to said coil legs, each of said plates being located at a predetermined distance in front of each respective coil leg of said plurality of tube coils as counted in the direction of flow of said first medium, and said spray holes in each plate being separated into rows, with each row being positioned in line with, and directly in front of, a coil leg of one of said tube coils.
