Description
Technical Field
The utility model relates to a monomer cylinder head for engine.
Background
The cylinder cover is used for sealing the cylinder, forming a combustion space together with the piston and bearing high-temperature and high-pressure fuel gas. The cylinder head is subjected to mechanical loads caused by gas forces and tightening of the cylinder bolts, and also to high thermal loads due to contact with the hot gases. In order to ensure a good sealing of the cylinder, the cylinder head can neither be damaged nor deformed.
The heat dissipation design of the cylinder head is particularly important in order to ensure that the cylinder head is not burnt by excessive temperature in long-term use. The existing single cylinder cover usually depends on heat dissipation of the outer surface of the single cylinder cover or air cooling heat dissipation, after long-term use, the temperature cannot be guaranteed to be constant, and once the temperature exceeds the maximum bearing range, the single cylinder cover is easy to damage, so that the integral fault of an engine is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing a single cylinder cover for an engine.
A unitary cylinder head for an engine, comprising a cylinder head body; the side wall of the cylinder cover main body is connected with an installation plate, a cavity is arranged inside the installation plate, a heat conduction copper pipe is arranged in the cavity, the heat conduction copper pipe is spirally arranged in the cavity of the installation plate in a zigzag manner, a water inlet and a water outlet are respectively arranged at two ends of the heat conduction copper pipe, and the water inlet and the water outlet are both connected with a water pump; a through groove is formed in the mounting plate, and a cooling fan is arranged at the opening of the through groove.
Preferably, the cylinder head main body is provided with an air inlet and an exhaust port, and a spark plug mounting hole is arranged between the air inlet and the exhaust port.
Preferably, the heat conduction copper pipe is connected with the cylinder cover main body through sealing silica gel.
Preferably, the mounting plate is T-shaped.
Preferably, the heat conducting copper pipe is made of red copper.
Preferably, the surface of the mounting plate is provided with a heat insulation layer, and the lower surface of the heat radiation fan is in contact with the outer surface of the heat insulation layer.
Has the advantages that:
through surperficial heat conduction copper pipe and inside coolant liquid, can be very fast with the outside discharge of heat that produces in the cylinder head main part, and in order to prevent that the unable cooling demand that satisfies after the rising of inside coolant liquid temperature, further cool down it through installing radiator fan additional at the middle part of heat conduction copper pipe.
When the cooling device is used, the cooling fan carries out air-cooled cooling on the heat conduction copper pipe, namely, the middle part of the heat conduction copper pipe is cooled, so that the temperature difference between the head and the tail of cooling liquid in the heat conduction copper pipe is not too large, and the uniform heat dissipation capacity of the heat conduction copper pipe on the surface of the cylinder cover main body is ensured.
