Abstract

This invention relates to heat engineering. The invention allows to intensify heat exchange. In the housing 1 is placed a rotor, made in the form of a system of truncated cones (CC) 2. The latter are concentrically fixed on the drain pipes 3. On the inner sides of CC 2 there are fixed spiral thin-walled tubes 4 with open ends. A fluid distributor (L) is installed in front of the rotor, made in the form of a vane guide vane with longitudinal discharge slots. Hot air goes to the Hollow blades of the guiding apparatus and through the exit slits gets onto the surface of UK 2 from the side of smaller bases. The liquid spreads over the surfaces of the CC 2 with a thin film and moves towards the channel 5 for collecting the cooled oil. At the same time, the liquid is intensively mixed and flows through the tubes 4. From the channel 5, the liquid is removed from the heat exchanger. 2 Il. (L / 1 / Hudnocmt Air (jO o O N5 00 Oi

Description

The invention relates to heat engineering, and more specifically to heat exchangers with direct contact of heat transfer fluids, and can be used in energy, transport, chemical and refrigeration engineering.

The aim of the invention is the intensity of heat transfer.

FIG. 1 shows a heat exchanger; FIG. 2 is a section A-A in FIG.

The heat exchanger contains a housing 1 in which a rotor is placed, made in the form of a system of truncated cones 2 concentrically fixed on the water pipes 3, and on the inner sides of the truncated cones 2 spiral thin-walled tubes 4 with open ends are fixed. The heat exchanger has a common channel 5 for collecting the cooled liquid, a rotor drive 6 and a liquid distributor installed in front of the rotor in the form of a vane guiding apparatus with longitudinal outlet slots 7 connected to the distribution chamber 8.

During operation, heat transfer from the distribution chamber 8 is supplied to the hollow blades of the guide, in the form of a blade guide distributor of the distributor} of the fuel valve with longitudinal slots

the bones and through the exit slots 7 fall onto the surface of the truncated cones 2 from the side of smaller bases, spread over them with a thin film and move towards the channel 5, while intensively mixing and flowing through the thin-walled tubes 4. The cooled liquid flows through the tubes 4 into the circumferential channel 5 and removed from the heat exchanger. The cooled air passes through the heat exchanger, cooling the liquid, and the heated and humidified air is released into the atmosphere.
