ABSTRACT:
A sinuous shaped heat exchanger made up of a plurality of generally U-shaped heat exchanger units or sections or banks arranged with one of the ends of each of the U-shaped banks in opposing end to end relationship with one of the ends of a next succeeding bank in such a manner that places the outlet tube sheet of such bank supporting the outlet ends of the tubes of such bank face to face with the inlet tube sheet of the next bank supporting the inlet ends of the tubes of such next succeeding bank. The tubes at the outlet side of the outlet tube sheet and the tubes at the inlet side of the inlet tube sheet protrude toward each other beyond the surfaces of the tube sheets. A removable transition connecting piece in the form of an apertured plate with the same hole diameter and pitch as the tube sheets is sandwiched between the outlet tube sheet and the inlet tube sheet. It is removably secured in that position by securing it to the aforementioned ends of the banks. The protruding tubes from the two tube sheets fit snugly but removably into opposite ends of the holes in the transition plate thereby providing a plurality of continuous, unbroken and uninterrupted sinuous shaped passageways through and between the tubes of the plurality of banks.
