Described intake tunnel is comprised of water intake, thermostat valve seat, the exit of pump of side of cylinder block, and the passage that enters the thermostat valve seat from the cooling liquid of exit of pump enters cylinder block cooling water intake tunnel and/or cylinder head cooling water intake tunnel through the water intake of side of cylinder block;
Described exhalant canal is comprised of water outlet and the radiator of side of cylinder block; Enter radiator from the cooling liquid of cylinder block cooling water exhalant canal and/or the outflow of cylinder head cooling water exhalant canal through the water outlet of side of cylinder block.
Described thermostat valve seat is connected with water pump.
Described cylinder block cooling water exhalant canal and cylinder head cooling water exhalant canal are communicated with before entering the water outlet of side of cylinder block.
The water intake of described side of cylinder block is positioned at air inlet side or the exhaust side of cylinder body.
The water outlet of described side of cylinder block is arranged at air inlet side or the exhaust side of cylinder body.
The water intake of described side of cylinder block and the water outlet of side of cylinder block are positioned at the not ipsilateral of cylinder body.
Be provided with the cooling water runner at the water intake of described side of cylinder block and the cylinder body between the thermostat valve seat.
Water outlet and the cylinder body between the radiator at described side of cylinder block are provided with the cooling water runner.
The beneficial effect that the present invention compares with prior art is:
The cooling liquid water inlet position of motor is adjusted to the side of cylinder body from the front-end face of cylinder body, the water exit position of motor is adjusted to the side of motor from cylinder cap, a kind of brand-new engine-cooling system water inlet and outlet arrangement is provided, avoided the zone of motor centralized arrangement component, reduced the layout difficulty of turnover water pipe, the balanced weight distribution of engine component on motor reduces vibrations, also reduced the assembling difficulty of later stage motor.

Embodiment
Below describe technological scheme of the present invention in detail by specific embodiment, should be understood that following embodiment only is exemplary, only can be used for explaining and technological scheme of the present invention being described, and can not to be interpreted as be restriction to technical solution of the present invention.
In technological scheme of the present invention, cylinder block cooling water passage and the Cooling of Cylinder Head water channel of motor are prior art, because cylinder block cooling water passage and Cooling of Cylinder Head water channel in the existing technology have multiple variation, but, as long as exist cylinder block cooling water passage and Cooling of Cylinder Head water channel all can be applicable to the application's technological scheme.
Extremely shown in Figure 5 such as Fig. 2, engine coolant enters thermostat valve seat intake tunnel 4, enter water pump 12, after water pump 12 pressurizations, water intake by thermostat valve seat exhalant canal 11 and side of cylinder block enters cylinder body 1 again, and in the present embodiment, thermostat valve seat exhalant canal is integrated casting with cylinder body, in other embodiments of the invention, also can be that thermostat valve seat exhalant canal is independent pipeline.
Because cooling liquid intake tunnel herein design is at the exhaust side of motor, component that this place arranges are less, and transportable space is also larger, so all have very large adjustable space, the difficulty that reduces to arrange arranging and install.The cooling liquid of the water intake by side of cylinder block enters the intake tunnel 5 of cylinder body, enter cylinder block cooling water passage 6, whole cylinder body is cooled off, the cooling liquid of having cooled off cylinder body enters Cooling of Cylinder Head water channel 7 through water channel on the cylinder body, should upper water channel be conventional design, seldom give unnecessary details, after the cooling liquid that enters cylinder cap is cooled off cylinder cap, by the cooling liquid exhalant canal 8 on the cylinder cap and the cooling liquid exhalant canal 9 on the cylinder body, cooling liquid exhalant canal 8 and cooling liquid exhalant canal 9 are communicated with herein, cooling liquid enters the car load radiator through exhalant canal 9 finally by the water outlet 10 of crossing on the cylinder body, dispels the heat.
In other embodiments of the invention, the water intake of side of cylinder block is positioned at air inlet side or the exhaust side of cylinder body, or the water outlet of side of cylinder block is arranged at air inlet side or the exhaust side of cylinder body, or the not ipsilateral that the water outlet of the water intake of side of cylinder block and side of cylinder block is positioned at cylinder body all can be realized technological scheme of the present invention.
In other embodiments of the invention, the water intake of side of cylinder block can directly not connect with the thermostat valve seat, but connects by pipeline.The water outlet of side of cylinder block can directly not connect with radiator, but connects by pipeline.
The integral miniaturization of more and more stricter along with Abgasgesetz with cylinder cap, need the parts such as arranging exhaust air manifold, intake manifold, EGR, cooler for recycled exhaust gas and pressurized machine at cylinder cap, so the layout of engine water outlet is moved on the engine cylinder-body air inlet side, the selection space that this place can arrange is larger, reduce the difficulty of arranging, made things convenient for the integral arrangement of motor and the installation in later stage.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiments that scope of the present invention is by claims and be equal to and limit.
