tube teat exchanger

Technical parameters I.Use different Fluoroplastic tubes: diameter5,4,6,4.8,8,6.6,10,8,12 II.It is constructed of modular elements which enable the heat exchanger to be adapted to suit a particular vessel geometry.III.Design as per the customers’ special request Basic Calculations for heat transfer rate and surface1.According to the technical parameters required by customers 1). Tank Dimension: Length × width × height (actual liquid level) 2). Required temperature, Initial and final temperature of tank fluid 3). Time needed for cooling or heat up 4).Heat loss coefficient: Local ambient temperature, Structure of tank and factory workshop 5). For cooling: provide the temperature, voltage and operating time of rectifier2.Calculations for Heat Exchangers 1),Heat transfer rate: Q=V•C•r•B(t2-t1) kcal/h V:Solution volume (L) C: Specific heat of the solution (kcal/L·°C) r: Specific gravity of the solution (kg/L) T1: Initial temperature of tank fluid T2: Final temperature of tank fluid B: Heat loss coefficient (1.10—1.30) T: Time for cooling or heating up (h) 2) Heat transfer surface: S=Q/k•T Q: Heat transfer rate (kcal) K: Heat transfer Coefficient(Kcal/m²•hr·°C) T: mean temperature differencet: time set for heating up or cooling down (h)
