Description

Host cooling device of full-lift hovercraft

Technical Field

The utility model relates to the technical field of hovercraft, in particular to a cooling device for a main engine of a full-lift hovercraft.

Background

Unlike common ships, the bottom of the hovercraft is not in contact with the water surface when the hovercraft is sailed, so that the engine of the hovercraft can be selected from an internal circulation land machine instead of a common external circulation water cooler for the hovercraft. When the hovercraft runs at a high speed, the speed is not lower than 50km/h, the engine in the engine room runs continuously at a high power, because the hovercraft is a land-used internal circulation machine, if the hovercraft cannot be cooled quickly and well, the machine always alarms at a high temperature, and overheating and melting are easy to occur.

The general measures are that the cabin shed is heightened and widened, the cross section of the cabin is larger than that of a front cabin, the windward area is further enlarged, and the air intake is increased to cool an engine when the hovercraft sails. However, the method of increasing the windward side of the engine room causes the hovercraft to generate larger wind resistance when sailing, increases the loss of machine power, has adverse effects on the peak jump and speed increase of the hovercraft, and cannot continuously sail at high speed. The overall design of the hovercraft is also limited and not beautiful.
