At present, in nonferrous metallurgy industry extensively and the shell-and-tube widely applied and panel cooler, shell-and-tube floor space is big, heat exchange efficiency is low；Due to heat transferring plate thin (being generally 0.5-1.2mm), removable seal gasket is many, heatproof is low, perishable, easy to wear and dead angle fouling many, easy in the board-like passage of all welded type, inconvenience are cleaned, and spiral lamina cooler characteristic falls between, but spiral lamina is little by flow, how uneven channel cross-section sudden change is, use scope extremely limited.
At the industries such as petrochemical industry wide variety of tradition shell and tube cooler because the heat transfer area of unit volume is relatively low, heat transfer coefficient is not high, it is difficult to meet production requirement, and conventional helical plate is due to the amount of being processed (200-300m less than normal3/ h) restriction seldom selected.
Currently, domestic commonly used spiral-plate heat exchanger, restriction by method for designing and manufacturing process, the problems such as many products still exist that energy resource consumption height, local resistance be big, cross section of fluid channel amasss fouling that little, the abrupt change of cross-section brings more, abrasion, pressure drop are many, and the drawback such as disassembly, cleaning trouble is inconvenient, heat exchange efficiency is undesirable.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, fat pipe, uiform section runner spiral plate type cooler are proposed, avoid the spiral lamina caused after fluid conduit is widened and roll the untight problem of laminating, ensure that when bigger fluid conduit cross-sectional area, roll rear screw plate and remain to laminating closely, and ensure that circulation is unobstructed, do not block, non-scaling；Increase the effect of coolant turbulent flow, improve overall heat-transfer coefficient；Ensure that stablizing of coolant and hydrothermal solution flow velocity, it is ensured that do not stay dead angle.
