ABSTRACT:
A modular heat exchanger comprises modules connected in parallel. Each module represents by itself a casing inside of which there is provided a bundle of straight pipes for the first coolant; the open ends of the straight pipes adjoin tube plates. The latter are secured on the casing which has an inlet and outlet for the second coolant coming into contact with the intertube space. The modules are arranged in a shell for a first coolant, to pass therethrough which is fed into the straight pipes and the space between said modules. The shell is provided with an inlet and outlet for the second coolant. Displacers are arranged in the space between the modules, over the entire length of the latter, which displacers ensure equality of the heat-exchange coefficient inside the straight pipes and between the modules. The method of the operation of the modular heat exchanger is as follows: The first coolant is fed into the straight pipes of the module and into the shell, which coolant comes into contact, correspondingly, with the inner surface of the straight pipes and the outer surface of the modules' casings; the second coolant is fed into the inter-tube space of the module, which coolant comes into contact with the outer surface of the pipes and the inner surface of the casing of the module.
