FIELD: technological processes.
SUBSTANCE: device for processing one fluid equipped with at least one elongated film. Film is made from heat-conducting film, membrane film or combination thereof. Film is made in form of plurality of alternating layers of film. Between two opposite film layers there is spacer, which is permeable, parallel to layers of film. Layers of film and spacer extend spirally around central axis. Device contains multiple tubular supports. Each spacer is connected to first and second ends with one of said tubular supports. First tubular supports are located each between two layers of film. Second tubular supports are located between two successive first tubular supports. Tubular supports near central axis are alternately connected with first and second channels of fluid medium. Tubular supports are made with hole facing spacer made with possibility of operation as channel to feed or discharge fluid medium. Axial ends of spirally wound layers of film are sealed by seal.
EFFECT: simplified manufacturing of device.
