A kind of low-temperature refrigerated cabin for catches of sea fishing boats

Abstract

The invention discloses a low-temperature refrigerating cabin for fish catches of a sea fishing boat. The low-temperature refrigerating cabin comprises a cabin body and a heat insulating plate for dividing the cabin body into a quick-freezing cabin and a thermal insulation cabin, wherein a refrigerating medium U-shaped coiled tube is arranged on the inner wall of the quick-freezing cabin and the inner wall of the thermal insulation cabin; a flat plate quick-freezing device is arranged in the quick-freezing cabin; the flat plate quick-freezing device comprises a supporting framework, a refrigerating medium liquid outlet header tube and a refrigerating medium liquid inlet header tube; a plurality of hollow quick-freezing flat plates are arranged on the supporting framework; elastic buffer mechanisms are arranged among the quick-freezing flat plates and the supporting framework; liquid inlets and liquid outlets in the quick-freezing flat plates are connected to the refrigerating medium liquid inlet header tube and the refrigerating medium liquid outlet header tube through flexible stainless steel connecting tubes; a left partition plate and a right partition plate are arranged in eachquick-freezing flat plate, a turbulent-flow region is formed in an area between the left partition plate and the right partition plate, the turbulent-flow region is equipped with a turbulent-flow bump, a heat exchange region is arranged in an area except from the left partition plate and the right partition plate, a heat exchange partition plate is arranged in the heat exchange region; and refrigerating medium runners are formed in gaps among the heat exchange partition plates. The low-temperature refrigerating cabin has the advantages of being high in quick-freezing speed, convenient in fishcatch obtaining, relatively good in universality and economical efficiency, and the like.

Description

technical field [0001] The invention relates to a fishing boat, in particular to a low-temperature refrigeration cabin for catches of a sea fishing boat. Background technique [0002] In pelagic fisheries, in order to ensure the quality of the catch as much as possible, the catch must be quickly sorted, frozen, stored and transported below -18°C after being caught on board. [0003] On existing sea fishing boats, freezers are usually used to quickly freeze the catch, and then the frozen catch is transferred to the insulation cabin (-18°C) in the hull for low-temperature preservation. The freezer is used for quick freezing, and the capacity is small. The energy consumption is high, and it is very inconvenient to pick and place the catch. In addition, the current insulation cabin usually uses a compressor using Freon as the refrigerant for refrigeration, which is noisy, slow in cooling speed, and not environmentally friendly.

AI Technical Summary

Problems solved by technology

The refrigerated cabin uses semi-conductor for cooling, which has the following defects: (1) The components of the semi-conductor refrigeration chip are made of high-purity rare materials, and the process conditions are not yet mature, resulting in relatively high cost of components; Under normal circumstances, the refrigeration efficiency of semiconductor refrigerators is lower than that of mechanical compression refrigerators, and can only be used as low-power refrigerators. In the case of large cooling capacity, the cost per unit of cooling capacity is high; It is easy to be blocked by dust, and it cannot be cleaned, and it is easy to burn due to high temperature; (4) The hot end of the semiconductor refrigeration chip generates a large amount of heat. In the case of large cooling capacity, the heat dissipation requirements are very high. Larger volume cooling mechanism
