Calculation of heat exchange area for heat exchangers
Thread Content
Are there any simple empirical values for the calculation of this heat exchanger? I think the calculation formula is really complicated, right? I don’t need a very large heat exchanger, nor is there a high flow rate required. The design should be based on the parameters of the system under evaluation: for example, for H2, the flow rate is 1 liter per minute, the pressure is 10 megapascals, and the temperature is 300 degrees. To bring this temperature down to room temperature, what size heat exchanger is needed? For instance, a coiled tube or shell-and-tube heat exchanger might be used. In the case of normal temperature water, what area does my heat exchanger need, and what should be the flow rate of the water?
Shouldn’t it be room temperature water? For normal-temperature water, would a very large heat exchanger be required to bring hydrogen at 300 degrees down to room temperature? It would be better to use cold water, as this way the heat exchanger does not need to be large. Is that so? Could the seniors advise me on how to calculate this?
With such limited capacity, if there’s enough space, just wind the tube a few times to allow natural cooling through conduction
So I’m thinking about this issue: since the volume is small, it’s actually not necessary to calculate the heat exchange area; a simple shell-and-tube heat exchanger will do. But how large should it be? It definitely can’t be too big, and it can’t be too small either; there must be a suitable size. How is this calculated?
