[0002] As we all know, a marine outboard cooler refers to a device that cools a diesel engine to discharge high-temperature fresh water. Take away the heat of high-temperature fresh water in the main engine body, so as to ensure that the engine can work normally within the design temperature range, so that the main engine can better exert its own power and save more energy. At present, the structure of domestic marine outboard coolers There are many types, such as bulwark cavity type, outboard cooling water tank type, keel type, diversion tube cavity type and grid type, etc. The grid type outboard cooler is to arrange the cooling pipes in parallel into a grid Shaped, the coolers are all embedded in the grooves provided on the hull shell. The grid-type outboard cooler has the least increase in the resistance of the hull and hardly affects the speed; the cooler has a compact structure, small dimensions, and K value (Thermal conductivity) is relatively large; its inlet

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings:

[0012] As shown in the figure, a cooling method for cooling circulating water of internal combustion engine of a glass fiber reinforced plastic ship is characterized by lofting according to the line type of the hull plate on both sides of the bottom keel, and then bending the cooling coil 1 that is consistent with the line type of the hull plate. , And then directly assembled on the outer side of the hull shell plate on both sides of the bottom keel through the coil pipe clamp code 2. One end of the cooling coil 1 is connected with the outlet pipe of the power unit, and the other end of the cooling coil 1 is connected with the fresh water pump inlet of the power unit Connected to form a closed cooling system. The heat of the fresh water in the tubular outboard cooler is taken away by the outer seawater, which has the effect of cooling the fresh water. The cooled fresh wate...

Abstract

The invention discloses a cooling method and a cooling device for the recycled cooling water in the internal-combustion engine of the glass reinforced plastic boat, the device is characterized in that a cooling coil is made by lofting firstly according to the linetype of the shell plate at both sides of the bilge keel and secondly bending into the cooling coil which is in line with the linetype of the shell plate, then the coil is directly arranged at the outer side of the shell plate at both sides of the bilge keel through coil clamping code; one end of the cooling coil is connected with an outlet pipe of the drive device and another end is connected with a fresh water pump of the drive device to form a closed type cooling system, the heat of the fresh water in a tubular type outboard cooler is carried away by the seawater. The cooling method and the cooling device of the invention have the advantages of easy production, convenient assembly, energy conservation, good cooling effect, etc.; meanwhile, the speed of the boat is not affected.

Description

Technical field: [0001] The invention relates to a cooling method and device for cooling circulating water of an internal combustion engine, in particular to a cooling method and device for cooling circulating water of a glass fiber reinforced plastic ship internal combustion engine. Background technique: [0002] As we all know, the marine outboard cooler refers to the device that cools the diesel engine to discharge high-temperature fresh water. This device is directly installed on the outside of the hull plate below the ship's unloaded waterline, and depends on the seawater (or fresh water) outside the hull. Take away the heat of the high-temperature fresh water in the main engine body, so as to ensure the normal operation of the engine within the design temperature range, so that the main engine can better exert its own power and save more energy. At present, the structure of outboard coolers for domestic ships There are many types, such as sidewall sandwich type, outboard co...
