JPH01118083A - Cooling device for fish preserve of small-sized fishing boat - Google Patents

Abstract

PURPOSE: To provide a high cooling effect only with an engine pump and keep a freshness of fish contained in a fish preserve by a method wherein a thermal radiation tower is directly connected to a sea water inlet port, the thermal radiation tower and a cooling water pipe of an engine are connected and water is discharged out of a ship through an engine cooling sea water discharging port. CONSTITUTION: Sea water is taken into a ship through a cooling sea water inlet port 1 and the taken sea water passes through a gas thermal radiation tower 4 and a cooling water pipe B to cool an engine 2. After cooling operation, the sea water is discharged through an engine cooling sea water discharging port 3. Accordingly, gas of high temperature and high pressure compressed by a compressor 5 passes through a high pressure gas pipe 6 within the gas thermal radiation tower 4, the gas is cooled with surrounding sea water, passes through a pressure adjusting tank 7 and then the gas is injected through a nozzle 8. The injected gas is cooled rapidly, passes through a low temperature gas pipe 9 within a sea water cooling tower 10 and then cools the surrounding sea water and circulates to the compressor 5. In turn, sea water in the fish preserve 12 is circulated by a water pump 11 directly connected to the compressor 5 is circulated within the sea water cooling tower 10 to decrease a temperature of sea water within the fish preserve 12.

Description

[Detailed Description of the Invention] A) Industrial Field of Application This invention installs a low-cost cooling system that is less likely to break down in a small fishing boat with a narrow engine room, thereby lowering the seawater temperature in the fish tank and maintaining the freshness of fish. Regarding.

Conventional technology A cooling system specifically designed for small fishing boats with narrow engine rooms has not been developed, and small fishing boats use ice in the seawater in their fish tanks to keep the fish fresh, but the concentration of seawater changes. Sea - Lowering the water temperature alone was not enough to keep fish fresh.

c) Problems to be solved by the invention This invention makes it possible to install a cooling system exclusively for small fishing boats with small engine rooms, and requires only an engine pump without the need for a separate pump, which increases the cooling effect and improves the performance of fish pens. The purpose is to maintain the freshness of the fish.

2) Means for Solving the Problems This invention will be explained based on the drawings. Seawater from outside the ship is taken from the cooling seawater intake port 1 and piped directly to the gas heat radiation tower 4. Engine 2 via B
After cooling the engine, the engine cooling seawater drain port 3
Drain more seawater overboard.

E) Function Therefore, the high temperature and high pressure gas pressurized by the compressor 5 passes through the high pressure gas pipe 6 in the gas heat radiation tower 4, is cooled by the surrounding seawater, passes through the pressure regulating tank 7, and is injected by the nozzle 8. Ru. The injected gas is rapidly cooled and sent to seawater cooling tower 1.
The gas passes through the low temperature gas pipe 9 inside the 0, and is returned to the compressor 5 while cooling the surrounding seawater. On the other hand, the seawater in the fish tank 12 is circulated through the seawater cooling tower 10 by a water pump 11 directly connected to the compressor 5, thereby lowering the seawater temperature in the fish tank 12.

Effects of the Invention As explained above, this invention does not require a separate cooling pump and only requires a pump attached to the engine, and the cooling method of the gas radiating tower of the cooling device can be easily convexed, improving the cooling effect and improving the cooling effect in the engine room. Easy to fit into narrow small fishing boats and with fewer breakdowns.
It can be equipped with an inexpensive cooling device and is effective in keeping fish fresh.
