Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 1 to 4, comprise according to the concrete structure of the engine cylinder cooling water jacket structure of the specific embodiment of the invention: water intake 1, upper strata water channel 2, lower floor's water channel 3, machine oil cooler cooling jacket 4, connection water channel 5, jacket-cooling water cover 6 and upper water hole 7.Wherein, suction port 1 is opened in the feed-water end of upper strata water channel 2, the waterexit end of upper strata water channel 2 is connected with the feed-water end of machine oil cooler cooling jacket 4, cooler cooling jacket 4 is connected with lower floor water channel 3, machine oil cooler water jacket 4 bottom, lower floor's water channel 3 are overlapped 6 respectively by connection water channel 5 with jacket-cooling water again and are connected, and the top of jacket-cooling water cover 6 is provided with the upper water hole 7 be communicated with cylinder head.This engine cylinder cooling water jacket structure makes cooling water all by after the first cooling machine oil of machine oil cooler cooling jacket 4, flow in the jacket-cooling water cover of each cylinder of cylinder liner again, substantially increase the cooling effectiveness of machine oil cooler, in effective raising block jacket, the flowing velocity of cooling liquid, extends the working life of motor.
Wherein, upper strata water channel 2 is horizontally installed on as the intake tunnel of whole engine cylinder cooling water jacket structure the side that jacket-cooling water overlaps 6.Water intake 1 is opened in the feed-water end (left end) of upper strata water channel 2, and the cooling water that engine water pump exports enters upper strata water jacket 2 by water intake 1, and then enters whole engine cylinder cooling water jacket structure and carry out heat exchange.The waterexit end of upper strata water channel 2 is connected with the feed-water end of machine oil cooler cooling jacket 4, cooler cooling jacket 4 is connected with lower floor water channel 3, the cooling water that engine water pump exports is after upper strata the water channel 2 all first cooling machine oil of ingress engine oil cooler cooling jacket 4, part cooling water enters lower floor's water channel 3, cooling water all substantially increases the cooling effectiveness of machine oil cooler by the first cooling machine oil of machine oil cooler cooling jacket 4, avoid cooling water and enter the rear jacket-cooling water cover of inflow respectively and machine oil cooler cooling jacket from water intake, cause the cooling water inflow flowing into machine oil cooler cooling jacket limited, machine oil cooler cooling effect is poor, be unfavorable for the cooling to machine oil, and then cause engine oil coolant-temperature gage difference little, engine cooling lubricating function reduces, cause the faults such as engine movements part inordinate wear, reduce service life of aeroengine.
