Abstract

The invention relates to a heat exchanger suitable for multi-pressure-resistant shell underwater equipment and a using method of the heat exchanger. The heat exchanger suitable for the multi-pressure-resistant shell underwater equipment comprises pipe box cylinders which are arranged in parallel in an up-and-down interval manner; the two pipe box cylinders are transversely arranged; the two pipe box cylinders are supported and installed through a plurality of frames; the two tube box cylinders communicate with each other through a heat exchange tube bundle; a shell which penetrates left and right is surrounded outside the frames; the left end and the right end of the shell are open; end covers are arranged at the openings; a plurality of fresh water outlets are formed in the top surface ofthe shell; and a plurality of fresh water inlets corresponding to the fresh water outlets are formed in the bottom surface of the shell. The heat exchanger can be directly placed in seawater, the heat exchange work is achieved conveniently, through the large-caliber seawater inlets and the large-caliber seawater outlets can be conveniently realized, the trouble that seawater is conveyed into a heat exchanger in a cabin from a sea water pump in the prior art is avoided, and the heat exchanger is convenient and rapid to install and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of underwater inboard heat exchange equipment, in particular to a heat exchanger suitable for underwater equipment with multiple pressure-resistant shells and a method for using the same. Background technique [0002] At present, the heat exchangers used in underwater equipment can be divided into plate heat exchangers and shell and tube heat exchangers according to the type. [0003] The plate heat exchanger is mainly composed of partitions, fins, seals, etc. The corrugated fins are sandwiched between two layers of partitions, and the two sides are sealed with seals to form the basic heat exchange unit of the plate heat exchanger. Among them, the corrugated fins can be rectangular, triangular, corrugated, etc., and many such units are overlapped to form a plate heat exchanger. Adjacent cells, that is, on both sides of the partition, flow fluids of different temperatures, and transfer heat through flat plat...
