The utility model provides a prevent plate heat exchanger slab of marine microorganism jam, the slab is rectangular ripple slab, including the symmetry set up in angular hole district, guard zone, water conservancy diversion district and the main heat transfer district at slab both ends, the junction of water conservancy diversion district and guard zone forms two seal groove central lines of chevron form, the connecting line between water conservancy diversion district and the main heat transfer district is the arc line, and main heat transfer district is equipped with continuous chevron ripple, does not establish the strengthening rib in horizontal and vertical direction, and every chevron ripple horizontal direction's central contained angle beta is 50~ 130, and central contained angle beta falls into the fillet, and the radius of fillet is 20mm-30mm, and ripple pitch t is 3-4 times of ripple degree of depth.
Preferably, the corrugation depth of the main heat exchange area is 4.5-5.0mm.
Preferably, each corrugated unit of the main heat exchange area comprises a wave crest, an inclined plane and a wave trough, the longitudinal section of the corrugated unit is triangular, and the included angle alpha between the wave trough or the two inclined planes of the wave crest is 80-110 degrees.
Preferably, the flow guiding area comprises a plurality of concave and convex hulls symmetrically and alternately arranged along the central line of the length direction of the plate, and the connecting line of the central point of the concave hull and the connecting line of the central point of the convex hull are respectively parallel to the central lines of the two sealing grooves.
Preferably, the concave and convex hulls are one or more than two of round, square or water drop shape.
According to the invention, by optimizing the modes of the corrugated shape, the corrugated depth, the section form, the flow guiding area structure and the like of the main heat exchanging area of the plate, the seawater is distributed more uniformly in the plate heat exchanger without dead zones, the passing performance is better, marine microorganisms are prevented from depositing on the plate to generate blockage, the heat exchanging efficiency of the product is improved, and the service life of the product is prolonged.
The corrugated depth of the main heat exchange area is designed to be 4.5-5.0mm, the sectional area of the channel is enlarged, and seawater and impurities are easy to pass through;
The main heat exchange area is regular continuous herringbone waves, so that independent waves are reduced, and the risk of marine organism wall hanging is reduced; the included angle alpha between two inclined planes of the trough or the crest is 80-100 degrees, the longitudinal section of the corrugated unit is triangular, and the contact area formed by two plates is smaller, so that the blockage can be reduced; the included angle beta of the center of the horizontal direction of the herringbone corrugation is 50-130 degrees, and can be adjusted according to the requirements of heat transfer and pressure drop; the center included angle beta is rounded into a round angle, the radius of the round angle is 20mm-30mm, and the small curvature treatment is adopted, so that the transition at the included angle is as gentle as possible, sand and microorganisms in the seawater are not easy to gather at the herringbone included angle, and impurities can quickly pass through the surface of the plate and are not easy to deposit.
The length of the main heat exchange area can be changed according to the requirements, and the length of the plate is increased or shortened by changing the length of the profiling mold core, so that the effective heat exchange area can be flexibly adjusted.
The flow guide areas of the plates adopt concave and convex hulls which are arranged in a staggered way to form a positive and negative round hull structure, and the flow guide areas are symmetrically distributed along the length direction of the plates, so that single-side flow or diagonal flow channel combination can be realized. Compared with the traditional chocolate block structure, the structure can only realize single-side flow or diagonal flow, and the positive and negative round package structure can be used under more working conditions. The flow guide area of the positive and negative round package structure is more uniform in flow field distribution and smaller in pressure drop compared with the flow guide area structure with the herringbone waves extending out.
The central point connecting line of the concave bag and the central point connecting line of the convex bag of the flow guiding area are respectively parallel to the central lines of the two sealing grooves, offset, and are arranged in a mirror image along the central line of the length direction of the plate. When the plates are assembled, one plate rotates 180 degrees, and just the convex hull and the concave hull are overlapped to form the contact.
The adjacent areas of the flow guiding area and the main heat exchange area are connected in an arc shape, so that the rigidity of the plate can be effectively enhanced.
