Сравнение типов и характеристик кожухотрубных теплообменников


Сравнительная таблица типов и характеристик кожухотрубчатых теплообменников

TypeStructural CharacteristicsTypical ApplicationsAdvantagesDisadvantages
Fixed Tube SheetTubes are fixed at both ends to the tube sheetSmall temperature difference, infrequent shell-side cleaningSimple structure, low costDifficult to clean shell side, not suitable for high temperature differences
Floating HeadOne end is fixed, the other end can move (floating)Large temperature difference, fouling fluids, frequent cleaningEasy to clean, accommodates thermal expansionComplex structure, higher cost
U-tubeTubes are bent into U-shape, fixed at one end onlyHigh thermal expansion conditionsCompact, good thermal expansion compensationDifficult to clean tube interiors, can't replace individual tubes
Double Tube SheetTwo tube sheets to separate fluids completelyPharmaceutical, food, corrosive mediaPrevents cross-contamination of fluidsHigher cost, more complex
Helical BaffleHelical flow path with spiral bafflesHigh-viscosity or fouling-prone fluidsLower pressure drop, higher efficiency, less foulingHigher manufacturing cost, complex design
