A cylinder head cover with cooling function

Abstract

The invention discloses a cylinder head cover with a cooling function. The cylinder head cover comprises a cylinder head cover body. A wavy upper side wall is formed at the upper end of the cylinder head cover body. A sealing cover plate is arranged on the upper portion of the upper side wall. The sealing cover plate is fixed on the upper end plane of the cylinder head cover body through a plurality of bolts. The upper end plane is higher than the wave crest end of the upper side wall. A sealing pad is clamped between the sealing cover plate and the upper end plane. The upper end portion of the cylinder head cover body, the sealing cover plate and the sealing pas form a cooling cavity. The two ends of the cylinder head cover body are each connected with a cooling liquid pipe assembly communicating with the cooling cavity. One of the two cooling liquid pipe assemblies is used for input, and the other cooling liquid pipe assembly is used for output. A cooling cavity is formed in the cylinder head cover and can be connected with condensed water, the condensation effect of oil mist can be effectively improved, thus, oil can flow back to an oil sump in time, and an engine can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of cylinder head covers, in particular to a cylinder head cover with a cooling function. Background technique [0002] The cylinder cover is the cover that covers the engine block. The first and most basic function is to cover and seal the cylinder head, keep the oil inside, and isolate pollutants such as dirt and moisture from the outside; the cylinder head The second function of the cover is to isolate the oil from the air. During the operation of the engine, oil mist will be formed, and the cooler inner surface of the cylinder head cover will gather the oil mist, causing the oil to condense and flow back down into the oil pan, but when the external ambient temperature is high, the inner surface of the cylinder head cover The surface temperature also increases accordingly, and the ability of the cylinder head cover to drive the oil mist to condense is weakened, and the oil cannot be returned to the oil pa...

Problems solved by technology

During the operation of the engine, oil mist will be formed, and the cooler inner surface of the cylinder head cover will gather the oil mist, causing the oil to condense and flow back down into the oil pan, but when the external ambient temperature is high, the inner surface of the cylinder head cover The surface temperature also increases accordingly, and the ability of the cylinder head cover to drive the oil mist to condense is weakened, and the oil cannot be returned to the oil pan in time, which reduces the amount of oil, which will have a greater impact on the cooling and lubrication of the engine. influences
