Description

The invention relates to heat exchange apparatus and can be used in the energy industry. A heat exchanger made of half-rings embedded in tube sheets and connected by means of collectors for supplying and discharging working media 11 is known. A disadvantage of this heat exchanger is the complexity of the manufacturing process and its considerable size. The closest solution to the proposed one is a submerged heat exchanger, containing annular pipes washed by the working medium, connected to the dispensing and collecting manifolds and mixing chamber, separated by means of a septal distributor 23. The disadvantage of such a heat exchanger is a low coefficient of heat transfer that tends to increase dimensions and reduces the manufacturability of the assembly as a whole, the purpose of the invention is to intensify heat exchange. This goal is achieved by the fact that in an immersion heat exchanger containing a washing fluid, a col. target pipes connected to the distributing and collecting collectors and the mixing chamber, divided by partitions, the partition separating the collectors are L-shaped, and the collectors themselves and the distributing chamber are equipped with through-passages for the working medium, oriented perpendicular to the planes, pipes, FIG. 1 schematically shows a heat exchanger, top view; in fig. 2 section A-A in FIG. one; FIG. 3 is a section B-B in FIG. 1; FIG. 4 is a section B-B of FIG. 1; in fig. 5 - opi-j discharge heat exchanger, side view. The immersion heat exchanger contains annular tubes 1 connected to distributing 2 and collecting 3 collectors and mixing chamber 4, separated by partitions 5 and b, Partition 5 separating collectors 2 and 3, is L-shaped, and the collectors 2 and 3 and the mixing chamber 4 is provided with through pipes 7 for the working medium, oriented perpendicular to the planes of the pipes 1, the Manifolds 2 and 3 are provided with an inlet 8 and a discharge pipe 9, respectively, and the heat exchanger is placed in the housing 10 and the plates are fixed to it Oops 11, Heat exchanger works as follows. The immersion heat exchanger is placed in the housing 10 by means of the plate 11. The working medium is filled with the cavity of the housing 10 and is pumped through to ensure the flow of the working medium through the through pipes 7, the coolant is supplied through the pipeline 8 and the collector 2 to the annular pipes 1, heat exchange with the working fluid takes place medium flowing both between the pipes 1 and the nozzles 7. The heat carrier is removed through the collector 3 and the pipe 9, the proposed heat exchanger facilitates the heat exchange process with high ntami heat transfer and improve the manufacturability of the assembly as a whole.
