Radial-axial bidirectional centrifugal-type rotating plate-fin-type heat exchanger

Abstract

The invention provides a radial-axial bidirectional centrifugal-type rotating plate-fin-type heat exchanger. The problem that relative rotating movement exists between a heat exchanger and a refrigeration system main body or the problem of the heat exchanging process that fluid needs to enter axially and comes out radially is solved. The radial-axial bidirectional centrifugal-type rotating plate-fin-type heat exchanger comprises a cylindrical core body structure, the core body structure is provided with a first axial flow channel, a second axial flow channel and a third axial flow channel which are formed in the axial direction of the core body structure, the first axial flow channel is formed along a center shaft of the core body structure, and the second axial flow channel and the thirdaxial flow channel are located on the two sides of the first axial flow channel; the core body structure is provided with a plurality of layers of first radial flow channels and second radial flow channels which are sequentially arranged at intervals in the radial direction of the core body structure, the inner ends of the first radial flow channels serve as opening ends and communicate with the first axial flow channel, and the outer ends of the first radial flow channels serve as opening ends and communicate with the outside world; and one ends of the second radial flow channels communicatewith the second axial flow channel, and the other ends of the second radial flow channels communicate with the third axial flow channel. According to the compact heat exchanger, when the relative rotating movement exists, the heat exchanging effect is not affected, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a radial-axis bidirectional centrifugal rotary plate-fin heat exchanger. Background technique [0002] For the case where radial heat dissipation is required in the circumferential space, the large-diameter space generally arranges the radiator in the circumferential direction. Due to the heat exchange method, it usually requires complex air ducts and complex process design. Domestic Wen Xueyou, Li Zhuo, etc. in the literature "Simulation of Intercooler for Marine Gas Turbine with Complex Cycle" propose the design scheme of the intercooler and air duct structure as follows: In order to meet the large-diameter axial heat dissipation, the heat exchange modules are evenly distributed in the circumferential direction , quantity 8 to 12 pieces. In order to satisfy the uniform distribution of the air flow of each heat exchange module uniformly distributed in the circumferential ...
