Abstract
The invention belongs to the design field of engine body structures, and in particular, relates to an engine body cooling system. The engine body cooling system comprises a cooling cavity formed between an engine shell and engine cylinder barrels; at least four cylinder barrels are horizontally arranged, so that the cooling cavity is divided into a left cavity and a right cavity; the left cavity and the right cavity are communicated at two ends; the outer walls between adjacent two cylinder barrels are connected as a whole; a water baffle plate aligned to a water inlet is arranged between the cylinder barrel near the water inlet and the engine shell; and the water baffle plate can reduce the flow of water entering the right cavity. The engine body cooling system cancels water passing channels among all the cylinder barrels, and improves the yield of engine body castings; and meanwhile, in order to effectively improve the flowing speed and the flow of cooling water in the left cavity, the water baffle plate is arranged in the water inlet of the right cavity, so that the flow of the cooling water in the right cavity is reduced, and most cooling water can directly enter the left cavity from end channels of the two cavities.
Description
Technical field
The invention belongs to engine body field of structural design, be specifically related to a kind of engine body cooling system.
Background technique
As shown in Figure 1, the cooling water path of water cooled engine is: the cooling water from radiator is introduced into body inner chamber from water intake 10 and cools body from right chamber 12 to left chamber 11 after water pump, upwards after cylinder liner passage 14, enter cylinder cap again, the air inlet side on the right is cooled after first cooling the exhaust side on the left side, hot water after being heated is got back to radiator and is cooled after the thermostat base and thermostat of front end, completes cool cycles process.Wherein cooling water is from the front end and back end passage needed during the right side of body to left side through cylinder bucket.Except this passage, in order to strengthen the cooling effect of the higher left side exhaust side of temperature, needing the water velocity and the flow that suitably improve the left side, needing to cast or process between the cylinder bucket and cylinder bucket of body to appear water channel 13 for this reason, number of channels is four-cylinder 3 place, six cylinder machine 5 places.Between existing machine body cylinder bucket and cylinder bucket to cross water channel 13 be is formed by cast, in order to the total length of as far as possible shortening body, this width crossing water channel is less than 5mm, length and be highly all greater than 40mm.The shortcoming of this catwalk has: 1, the easy drop in loam core during casting, caused water channel to stop up; The cylinder bucket wall thickness of passage both sides is 3-4mm, if mo(u)ld core deviation is slightly large, causes wall unevenness even, even communicates with cylinder bucket inwall.Above 2 all cause the rate rising of body foundary loss and decrease in yield, thus cause cost increase; 2, this passage reduces the strength and stiffness of cylinder bucket, is unfavorable for the performance and reliability of motor.
Summary of the invention
The object of this invention is to provide a kind of engine body cooling system, this cooling system under the prerequisite ensureing cooling effect, can improve the yield rate of cast blocks.
For achieving the above object, the invention provides following technological scheme: a kind of engine body cooling system, comprise the cooling chamber formed between engine casing and engine cylinder bucket, described cylinder bucket is at least four word orders, cooling chamber is made to be divided into left chamber and right chamber, and left chamber is communicated with right chamber two ends, outer wall between two adjacent cylinder bucket is connected as a single entity, one end of described right chamber is provided with water intake, the top of described left chamber is provided with the passage with Cooling of Cylinder Head chamber, manger board just on the lower side to water intake is provided with near between a cylinder bucket and engine casing of described water intake, this manger board can reduce the water flow entering right chamber.
Optimize, described water intake (26) is positioned at the middle part of right chamber (23) one end, and described manger board (25) is arranged on the lower semisection outer wall of cylinder bucket (21).
Optimize, described manger board (25) is provided with hollow part.
Optimize, the left side at described left chamber (22) place is the side at place, exhaust passage on cylinder cap, and the right side at right chamber (23) place is the side at cylinder cap upper air passage place.
Optimize, described passage (24) for multiple, and is evenly distributed on the top of left chamber (22).
Technique effect of the present invention is: eliminate the water channel excessively between each cylinder bucket, improve the yield rate of cast blocks, simultaneously in order to effectively improve cooling water flow velocity and the flow of left chamber, manger board is provided with in the water inlet of right chamber, right chamber cooling water flow is reduced, and most of cooling water directly can enter left chamber from the end run of two chambers.
Accompanying drawing explanation
Fig. 1 is the structural representation of engine-cooling system in prior art;
Fig. 2 is structural representation of the present invention;
Fig. 3 is perspective cut-away structural representation of the present invention.
Embodiment
As Fig. 2, shown in 3, a kind of engine body cooling system, comprise the cooling chamber formed between engine casing 20 and engine cylinder bucket 21, described cylinder bucket 21 is at least four word orders, cooling chamber is made to be divided into left chamber 22 and right chamber 23, and left chamber 22 is communicated with right chamber 23 two ends, outer wall between two adjacent cylinder bucket 21 is connected as a single entity, one end of described right chamber 23 is provided with water intake 26, the top of described left chamber 22 is provided with the passage 24 with Cooling of Cylinder Head chamber, near being provided with just to the manger board 25 of water intake 26 between a cylinder bucket 21 and engine casing 20 of described water intake 26, manger board 25 is for reducing the water flow entering right chamber 23.
As shown in Figure 3, as the preferred embodiments of the present invention, described water intake 26 is positioned at the middle part of right chamber 23 one end, and described manger board 25 is arranged on the lower semisection outer wall of cylinder bucket 21.
As another embodiment of the present invention, described manger board 25 is provided with hollow part, baffle plate is arranged to Pierced structure can play the effect slowing down flow velocity equally, under the enlightenment of the present embodiment, those of ordinary skill in the art should know, and other structures that can slow down water velocity can also be adopted to be used as manger board of the present invention.
Preferably, the left side at described left chamber 22 place is the side at place, exhaust passage on cylinder cap, and the right side at right chamber 23 place is the side at cylinder cap upper air passage place.
Preferably, described passage 24 is multiple, and is evenly distributed on the top of left chamber 22.
Present invention eliminates the water channel 13 excessively between each cylinder bucket 21, improve the yield rate of cast blocks, simultaneously in order to ensure cooling water flow velocity and the flow of left chamber 22, manger board 25 is provided with in the water inlet of right chamber 23, right chamber 23 cooling water flow is reduced, and most of cooling water directly can enter left chamber 22 from the end run of two chambers.
