Abstract
The utility model relates to a coil heat exchanger equipped with a plurality of septal path coils, which comprises a heat exchange shell, a plurality of heat exchange coils, a plurality of tube sheets, a tube side inlet and outlet, a shell side inlet and outlet. The utility model relates characterized in that a plurality of opposite-handed septal path coils are positioned among the single-layer or multiple-layer heat exchange tube bundles. The shell side medium of the utility model can transversely sideswipe the heat exchange tube bundles and greatly improve the heat exchanging efficiency. Regardless of the shell side inlet and outlet is tangential or central access, the flows of the swirl coil medium in the tube bundles are all a plurality of spiral flows in the septal path coils, and the tube side is on the standard spiral flow states. The resistances of the tube side and shell side are both small, but both have a higher transfer coefficient K; the heat exchange tube bundles can be used safely without temperature stress, and the heat exchanger has well reliability and stable heat exchange performance.
Description
Technical field
The utility model belongs to a kind of coil heat exchanger, particularly a kind of coil heat exchanger that is provided with every the journey coil pipe.
Background technology
The dish type heat-exchanging tube bundle of existing coil heat exchanger all is along same rotation direction setting, because essentially no slit between each layer of heat-exchanging tube bundle spirals, the flowing space of shell side medium is very little, and has only axial flow, do not have lateral flow, influence the heat exchange efficiency of heat exchanger.
The utility model content
The purpose of this utility model provides the coil heat exchanger of a kind of setting every the journey coil pipe, and the shell side medium can laterally skim over heat exchanger tube, and heat exchange efficiency is significantly improved.
The purpose of this utility model is achieved by the following technical solution: comprise heat exchanger shell, heat exchange coil, tube sheet, tube side import and export and shell side import and export, it is characterized in that: between the single or multiple lift heat-exchanging tube bundle, be provided with some rotation directions opposite every the journey coil pipe.Cut apart shell side runner in the housing with them, make the shell side medium enter shell side from the shell side import after, move along spinning every the journey coil pipe, flow out through outlet then, mass motion is laterally to skim over heat exchanger tube substantially.Heat exchange efficiency is significantly improved.With also participating in heat exchange after journey coil pipe itself.
The utility model has the advantages that: the shell side medium can laterally skim over heat exchanger tube, and heat exchange efficiency is significantly improved.No matter the import and export of eddy flow coil pipe shell side are tangential insert or the center is inserted, its medium flowing in tube bank all is at the spiral flow every between the journey coil pipe, and the tube side eddy flow state of standard especially.Also just because of these eddy flows, just make the eddy flow tray pipe heat exchanger of single tube journey, monoshell journey that superior performance is arranged: the resistance of (1) tube side, shell side is all little, but Coefficient K is all higher; (2) heat exchanger tube does not have temperature stress, so, heat exchanger tube self and as safe as a house with the weld seam meeting of tube sheet.The heat exchanger good reliability; (3) coil pipe is a helical form, and when coil pipe heating or cooling, surperficial dirt can come off automatically, and heat exchange property is stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be Fig. 1 tube bank part cross sectional representation (heat exchange coil and rotation direction opposite every journey coil pipe schematic cross-section.
The specific embodiment
See Fig. 1,2, concrete structure of the present utility model is as follows: tube side import and export 8,1 is set in the shutoff at heat exchanger shell 4 two ends, shell side import and export 3,7 is arranged on the both sides of heat exchanger shell 4, two ends assembling tube sheet in housing 4, technology post 6 is fixed between the tube sheet of two ends, is centered around technology post 6 heat exchange coil bundle 2 two ends on every side and is connected on the tube sheet of two ends.Between single or multiple lift heat-exchanging tube bundle 2, be provided with some rotation directions opposite every journey coil pipe 5, be connected on the tube sheet of two ends every the two ends of journey coil pipe 5.
