the heat exchanger, the cooler fluid will approach the inlet temperature of the hot fluid. Counter flow heat exchangers are the most efficient of the three types. In contrast to the parallel flow heat exchanger, the counter flow heat exchanger can have the hottest cold-fluid temperature greater than the coldest hot-fluid temperatue.

Horizontal baffles are often the default design, with many shell and tube heat exchanger calculations assuming that baffles will be installed horizontally, Koorosh Mohammadi explained in a thesis written for the University of Stuttgart.
اقرأ أكثرThe shell and tube heat exchanger in the photo above has about twelve times the efficiency than a hypothetical single-tube heat exchanger of the same size. However, there is a disadvantage to smaller tubes – if the fluid in your application is very viscous or has particulates, it can foul up the tube and undermine the heat transfer process.
اقرأ أكثرWhen the shell side heat transfer is sensible heating or cooling with no phase change, the baffle cut should be horizontal. This causes the fluid to follow an up-and-down path and prevents stratification with warmer fluid at the top of the shell and cooler fluid at the bottom of the shell.
اقرأ أكثرIn heat recovery applications, or where the application calls for increased thermal length to acheive effective overall Heat Transfer, shells can be installed with the flows in series. Up to six shorter shells in series is common and results in counter-current flow close to performance as if one long shell in a single pass design were used.
