Application of steel-titanium-aluminum composite joint to refrigerating system of fishing boat

Abstract

The invention discloses application of a steel-titanium-aluminum composite joint to a refrigerating system of a fishing boat. A mature steel-titanium-aluminum composite board in the market is used, and according to the specification of a refrigerating system pipeline, the steel-titanium-aluminum composite board is processed into a special composite joint; an aluminum evaporator and a steel pipeline are connected by the steel-titanium-aluminum composite joint, the steel pipeline is welded with a steel end of the composite joint, and the aluminum evaporator is welded with an aluminum end of the composite joint; and the connection way of the refrigerating system pipeline is a welding way which replaces the conventional flange connection, so that leakage in an interface position is avoided. Through the application, the leakage of a refrigerating agent at the interface position of the refrigerating system pipeline of the fishing boat is effectively avoided, the running stability of the whole refrigerating system is ensured, and thus the quality of fishes is ensured; and the steel-titanium-aluminum composite joint is applicable to the refrigerating system of the fishing boat, as well as a refrigerating system on land.

Description

Technical field [0001] The invention relates to an application, in particular to the application of a steel-titanium-aluminum composite joint in a fishing vessel freezing system. Background technique [0002] The fish caught by offshore or ocean-going fishing vessels need to be kept fresh. Fishery products that are kept fresh by freezing are usually stored in refrigerated compartments after being quick-frozen. Steel coils are generally used as evaporators in the refrigerated cabin, which are arranged around the bulkhead and on the ceiling deck. [0003] Due to the advantages of high thermal conductivity and fast heat transfer of aluminum, it is gradually accepted and replaced by steel coils as evaporators. However, since the main pipes of the refrigeration system are all made of steel, flange connection is generally used between the terminal aluminum evaporator and the steel pipe. [0004] For pipelines connected by flanges, due to the influence of hull vibration and gask...

AI Technical Summary

Problems solved by technology

[0004] For pipelines connected by flanges, due to the influence of hull vibration, gasket aging, etc., there will often be refrigerant leakage in the pipeline, which will lead to failure of the refrigeration system and directly affect the quality of fish products.

Seriously, the entire freezing system will fail, causing the entire boat of fish to rot directly
