A screen heat exchanger intended to cool or heat various fluid media in different branches of industry. The exchanger comprises alternating screens and spacers rigidly connected into a bank; the spacers have holes for the passage of the fluid medium. The screens are made of a sheet material whose heat conduction is higher than that of the material of the spacers. The screen elements forming the meshes are inclined to the plane of the screen.
