Abstract

PURPOSE:To prevent the titled heat exchanger from wear and vibration by making each heat transfer tube in each flow-turning part in a shell body absorb heat uniformly, by providing an approach passage consisting of a buffer plate and a shell body in the flow-turning zone at the inlet port of a shell body from which a fluid from the shell side is fed into the shell. CONSTITUTION:A fluid from the shell side, flowing into a shell body 1 from an inlet nozzle 1a, is branched off by a buffer plate 2, and flowing into the primary flow-turning zone 7a as shown by an arrow A along the shell body 1 via both left and right approach passages 13a and 13b, then flowing to the direction as shown by an arrow B which is opposed to the above-mentioned direction of an arrow A. With such an arrangement, the fluid fed into the shell can flow through the all zones among a cluster 4 of heat transfer tubes, then flowing into the secondary flow-turning zone 7b as shown by an arrow C via the cutout gap 6a of a primary baffle plate 5a, and after that it flows staggeringly toward an outlet and is discharged from an outlet nozzle 1b. Accordingly, the fluid on the shell side is prevented from producing a slack water zone of swirl flow on the back of a buffer plate 2, as a result, absorption of heat of each heat transfer tube can be balanced uniformly.

Since the other structures are the same, their explanation will be omitted. With this configuration, the body-side fluid flows through the guide channels 13a and 13b formed between the body IA and the buffer plate 2, and flows through each heat exchanger tube of the heat exchanger tube group 4 in the first folded flow section 7a. Since the heat exchanger flows slowly between the heat exchanger tubes, there is an advantage that the heat absorption of each heat exchanger tube can be made even more uniform.
