<p>PCT No. PCT/SE88/00565 Sec. 371 Date Apr. 16, 1990 Sec. 102(e) Date Apr. 16, 1990 PCT Filed Oct. 25, 1988 PCT Pub. No. WO89/03964 PCT Pub. Date May 5, 1989.The inventive device comprises a channel defined by a bottom and side walls having an inlet end and an outlet end for the flow of a refrigerant. Underneath the bottom there is provided transversely between the side walls an elongate first space. Substantially underneath the bottom and in association with the inlet end of the channel, an elongate second space is provided parallel to the first space. Between the first and the second space, at least one opening is so provided that a component of a flow rotating in the first space is guided substantially tangentially out of the first space and into the second space. The refrigerant therein is caused to rotate about the longitudinal axis of the second space, the second space being so connected to the inlet end of the channel that a component of the flow rotating in the second space is guided substantially tangentially out of the second space and in over the bottom so as to form a homogeneous flow of refrigerant in the channel.</p> |
