Description

Divider Cover Structure for Insulation of Ship Engine Part {DIVIDED COVER STRUCTURE FOR INSULATION OF SHIP ENGINE ASSEMBLY}

The present invention relates to a split type cover structure that insulates the ship engine, and more particularly, to reduce the noise generated by driving the engine while preventing vibration and noise, as well as implementing a flame retardant effect and improving mechanical strength. The present invention relates to a split cover structure for thermal insulation of a ship's engine unit, which can minimize heat insulation generated from the engine unit and block the temperature of outside air, and minimize fatigue of the engine unit.

The manifold installed in the engine part of a ship is a collection of several or all pipes for guiding intake or exhaust to each cylinder in a manifold polycylinder engine, and is divided into an intake manifold and an exhaust manifold.

The inlet manifold installed in the engine of the ship collects the gas generated during the combustion of the cylinder into one main pipe through each branch pipe to intake or discharge the engine.

Therefore, since the intake manifold sucks the outside air, an insulation device must be provided to prevent damage to the external device and overheating of the engine due to the blocking of the air inflow due to the freezing caused by the external temperature difference.

In general, a method of covering the engine of the manifold by using an insulating mat made of glass fiber or the like is used as the heat insulating cover method of the engine unit.

In addition, a method of shielding the outside of the engine cover and the parts belonging to the heat insulation cover and shielding the outside by installing a heat insulation cover for appearance reasons is widely used.

By the way, the insulation cover using the insulating mat has a problem that the heat load is added to the engine and its parts simply by having only the heat insulation function to the outside.

In addition, since the performance of the insulation mat deteriorates with time, the maintenance mat needs to be replaced after a certain period of time, and the insulation mat disposed of after replacement is using special equipment due to the problem of environmental pollution. Had to be disposed of.

In order to solve the problem of the insulating structure using the insulating mat, techniques for achieving a cooling action for the engine unit using the cooling water (water) have been studied.

The insulation structure using the coolant basically has a coolant passage therein to allow the coolant to flow therein, and forms a coolant inlet and an outlet to circulate the coolant due to the operation of the external coolant circulator.

Thus, through the insulating structure using the cooling water not only improves the cooling performance of the engine unit or its components, there are many advantages that can have a semi-permanent use cycle unlike the insulating mat method.

However, the insulation structure using the cooling water is generally manufactured integrally by molding to exclude the (welding) coupling part in consideration of leakage, corrosion, etc. of the circulating cooling water.

As a result, such an integrated insulation structure is difficult to manufacture and there is a problem that a considerable difficulty occurs in the installation work.

In particular, in the case of manufacturing a large insulation structure integrally, such as a medium-large engine for ships, the installation work was more difficult due to the heavy weight, and even if the initial insulation structure is completed, Even when maintenance is required, maintenance work on the part is impossible due to the integral insulation structure, and great inconvenience has arisen in the management.
