For spiral plate heat exchangers, how are the numbers of upper and lower clamps on the inverted conical flat cover determined? How is this calculated? Is there anyone who can provide some guidance? Payment is possible! ! ! :'(
In spiral plate heat exchangers, the number of upper and lower clamps on the inverted conical flat cover is determined based on specific design requirements. These requirements usually include factors such as fluid flow rate, heat exchange area, and heat exchange efficiency. Generally, the number of upper cards and lower cards is equal, as determined by the design requirements. Among them, the number of upper cards depends on the pressure loss at the fluid inlet and the flow velocity of the fluid, while the number of lower cards depends on the pressure loss at the fluid outlet and the flow velocity of the fluid. And these parameters need to be determined through calculation. To calculate the number of upper and lower plates, follow these steps: 1. Calculate the theoretical heat exchange area based on the specified thermal conductivity and temperature difference ； 2. Calculate the pressure loss at the upper and lower plates per unit heat exchange area based on the fluid flow velocity and design parameters ； 3. Based on the specified maximum allowable pressure loss and fluid flow rate limits, manufacture the corresponding number of upper and lower clamps. It should be noted that the specific calculation methods may vary depending on the design parameters and specific requirements. Therefore, it is recommended that when designing heat exchangers, professional engineers be consulted or specialized software be used for calculations and design to ensure that the requirements and safety standards are met. I hope the above information will be helpful to you! .
Shouldn’t it be related to stress? I’m a bit confused, but your answer seems very professional; any doubts?
The answer on the second floor was a bit confusing; the function of upper and lower clamps is similar to that of fasteners such as bolts and nuts. How is there any connection between them and factors like heat transfer coefficient, heat exchange area, pressure drop, and flow velocity?
Is it by calculating it as a bolt, selecting the bolt area first and then choosing the model?
