Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the corrugated sheet 1 is oval, the corrugated sheet 1 is composed of two semicircular plates and a rectangular plate clamped between the two semicircular plates, in this embodiment, the diameter of the semicircular plate is 560mm, the length of the straight line segment D of the rectangular plate is 280mm, and the width of the rectangular plate is equal to the diameter of the semicircular plate. The semicircular plate body is adopted, so that the heat transfer performance of the circular corrugated plate channels is superior to that of the rectangular corrugated plate channels, and the rectangular plate body is arranged to provide necessary plate body space for arranging oblique corrugations.
A fluid inlet 3 and a fluid outlet 4 are arranged on the central line of the corrugated plate 1; in this embodiment, the distance H between the centers of the fluid inlet 3 and the fluid outlet 4 is 690mm. The fluid inlet 3 and the fluid outlet 4 are circular openings with the same shape and size, the fluid inlet 3 and the fluid outlet 4 are respectively positioned in a semicircular plate body, and when a plurality of corrugated plates form the heat exchange plate group, a plurality of fluid inlets and a plurality of fluid outlets form a flow passage for two media to pass through. The fluid inlet 3 and the fluid outlet 4 are closer to the arc ends of the semicircular plate body, so that the middle oblique corrugated area is released, and the heat exchange efficiency is improved.
In the oblique corrugation arrangement, specifically, a main body of the corrugated plate 1 is provided with a plurality of runners 2 formed by oblique corrugations, the plurality of runners 2 are arranged together to form an oval, and the runner directions of the plurality of runners 2 are parallel to each other. In this embodiment, as shown in fig. 2, the wave distance S between two adjacent flow channels is 10mm, the depth D of the flow channel is 3.2mm, the wave bottom of the flow channel is smooth and close to sine wave heat transfer to the maximum extent, the smooth wave bottom avoids the heat transfer retardation phenomenon generated when a fluid flows through the plate, so that the resistance of the fluid is reduced, when a heat exchange plate set is composed of a plurality of corrugated plates, two adjacent corrugated plates are in contact with each other through the arc top of the flow channel, the arc top of the wavy flow channel is more smooth, so that the contact surface between the plates is obviously increased, the pressure resistance of the plate with the same size is enhanced, the deformation is reduced to the minimum, and the pressure-bearing capacity is improved. As shown in fig. 3, the included angle α between the flow channel 2 and the central line of the corrugated plate is 60 °, and the inclined corrugation is an inclined corrugation, which is relatively simpler than herringbone corrugation processing and has low manufacturing cost; and the bearing capacity is better than the horizontal straight corrugation, so a scheme with better heat transfer performance and better comprehensive performance is selected on the oval corrugated plate, and diversified use requirements are met. The oval corrugated plate sheet is suitable for a plate heat exchanger, and when the heat exchange plate sheet set is formed by a plurality of corrugated plate sheets, a sealing gasket is arranged between every two adjacent corrugated plate sheets to prevent fluid from leaking.
The utility model discloses an oval corrugated plate and plate heat exchanger through the two combination of the runner with oval corrugated plate and oblique ripple, remains better heat transfer performance and comprehensive properties, satisfies diversified user demand.
The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
