An inboard heat exchanger suitable for underwater equipment

Abstract

The invention relates to an inter-board heat exchanger suitable for underwater equipment. The inter-board heat exchanger suitable for the underwater equipment comprises a shell pass shell; the sectionof the shell pass shell is of an elliptic structure; end covers are mounted at the two ends of the shell pass shell; the structures of the end covers are matched with the section of the shell pass shell in shape; a fresh water inlet connecting pipe and a fresh water outlet connecting pipe are arranged at the top of the shell pass shell at intervals; a pipe box cylinders are arranged in the shellpass shell up and down at intervals; single pipe box cylinders are transversely arranged; two pipe box cylinders are fixedly connected through multiple spaced frames; the frames are connected with theinner wall surface of the shell pass shell; and two pipe box cylinders communicate through heat exchange pipe bundles. The inter-board heat exchanger suitable for the underwater equipment is directlyplaced in seawater, and is compact in structure and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to an inboard heat exchanger suitable for underwater equipment, which can perform seawater lateral flushing of heat exchange tube bundles. Background technique [0002] Heat exchangers suitable for underwater equipment can be divided into plate heat exchangers and shell and tube heat exchangers according to their structure. [0003] The plate heat exchanger is assembled by the corrugated plates according to the designed quantity and order to form a heat exchange channel with enhanced heat transfer effect, and there is a certain distance between different plates. There is a corner hole in each of the four corners of the heat transfer plate, which is mainly used for the entry and exit of cold and hot fluids. The hot and cold fluids flow into their respective channels, and flow through each plate in a countercurrent or downstream manner for heat exchange. A large numbe...

AI Technical Summary

Problems solved by technology

Although the shell-and-tube heat exchanger has a simple structure and low cost, its heat transfer capacity is relatively poor, and its volume and weight are relatively large.

[0005] These two heat exchangers are generally placed in the cabin, and the seawater is transported to the heat exchanger in the cabin by the seawater pump. Although this arrangement is easy to maintain, it needs to consume its own energy to drive the seawater pump, and it takes up space in the cabin.
