PCT No. PCT/SE85/00025 Sec. 371 Date Sep. 13, 1985 Sec. 102(e) Date Sep. 13, 1985 PCT Filed Jan. 23, 1985 PCT Pub. No. WO85/03563 PCT Pub. Date Aug. 15, 1985.A heat exchanger for exchange of heat between two media, especially gas and liquid, in heat pumps and the like, including an elongated, generally cylindrical space (2) passed through by one medium and having an inlet (3) arranged at one end and an outlet (7) at the other end, and a helical wall radially defining said space and delimiting a space through which the other medium is intended to flow. The novelty is that the inlet (3) into the cylindrical space (2) is tangentially arranged, whereby the tangent line through the inlet is generally parallel with a tangent drawn from the helical line of the wall, that between the two ends of the cylindrical space there is arranged a number of bodies (12, 12', 12') securing the intended circulatory movement, substantially blocking the central portion of the space in axial direction and adapted to utilize the interspace (11) between the coil turns as guide elements maintaining the media circulation, by guiding outwardly towards the wall the medium flowing through said space (2). |
