Heat insulation pipe penetration piece used for fishing boat refrigeration pipe

Abstract

The invention discloses a specialized pipe penetration piece for preventing the generation of a cold bridge to replace a traditional refrigeration pipe penetration method, so that the generation of the cold bridge is avoided and the requirements for cabin temperature are met. According to the pipe penetration piece, a sleeve is welded onto a steel plate instead of being directly welded onto a bulkhead or a deck, two layers of rubber plates and a layer of plank are arranged between the steel plate and the bulkhead or the deck, the steel plate and the bulkhead or the deck are fastened with bolts, the heat conductivity coefficient of the rubber plates and the plank is only about 1 / 250 that of the steel plate, temperature conduction is basically isolated, and in this way, the generation of the cold bridge is avoided, and then loss of refrigeration capacity is prevented.

Description

Technical field [0001] The invention belongs to the field of agriculture, forestry, animal husbandry and fishery. [0002] The invention relates to an application, in particular to an application of a heat-insulating through-chamber member for a freezing pipe of a fishing vessel. Background technique [0003] For the refrigeration system on fishing boats, because of the separation of the compartments, the refrigeration pipeline usually passes through the bulkhead or deck of each compartment from the refrigeration machine room to the evaporator of different compartments at the end. [0004] The freezing pipe passes through the cabin bulkhead or deck. The usual practice is to install a section of casing with an inner diameter larger than the outer diameter of the freezing pipe on the hull bulkhead or deck. The freezing pipe passes through the casing and enters other compartments. Between the freezing pipe and the casing Solder connection. [0005] Although this way of penetr...

AI Technical Summary

Problems solved by technology

[0005] Although this way of penetrating the cabin is simple, the direct welding connection between the freezing pipe and the bulkhead of the hull forms a cold bridge, which leads to the loss of cooling capacity of the refrigeration system

Especially in fish tanks with lower temperature requirements or ultra-low temperature, this way of penetrating the tank can no longer meet the requirements of the ambient temperature in the fish tank
