Abstract
The utility model discloses a water jacket capable of reasonably distributing water flows flowing to an upper part and a lower part, for a cylinder block. The water jacket comprises a flow channel arranged in the cylinder block (1) and oriented by surrounding the periphery of each cylinder hole (2), a flow channel inlet (3) arranged in the cylinder block (1), and a water flow guide surface (4) located behind the flow channel inlet (3); a flow splitting column (5) is further arranged in the flow channel part between the flow channel inlet (3) and the flow guide surface (4); the flow splitting column (5) comprises an upper part, a middle part and a lower part; intervals are arranged between the middle wall surface of the flow splitting column (5) and the middle wall surface of the flow channel, as well as between the lower wall surface of the flow splitting column (5) and the lower wall surface of the flow channel; and the part between the upper part and the middle part of the flow splitting column (5), as well as the part between the middle part and the lower part of the flow splitting column (5) are bonded or tightly matched with the corresponding wall surfaces of the flow channel.
Description
Technical field
The utility model relates to technical field of engines, specifically is a kind of cylinder body water jacket.
Background technique
In recent years; The reliability of motor compared strict 800 hours by original 300 hours up till now; On reliability, be greatly improved; Be Design of Cooling System and influence one of reliability most critical, promptly the reliability of cooling system and performance are the basic guarantees of the higher durable standard of motor.
In general, the design of cylinder body water jacket is a difficult point in the cooling system, the main one type of cooling up and down that adopts of all conventional engines cylinder body coolings; The center housing temperature characteristic distributions can be known (top dead center < cylinder body top>temperature is high, and lower dead center < inferior part of the cylinder block>temperature is low) during according to engine operation, and cylinder body top needs cooling effect to want better; Therefore the best type of cooling of cylinder body is that cylinder body top flow is big, water velocity is high, and the inferior part of the cylinder block flow is little, water velocity is low, can make cooling more reasonable like this; Cooling effect is better; And present cylinder body water jacket, the flow of its top and the bottom water, flow velocity basically identical we can say and do not distinguished; Thereby cause following defective; The cylinder body upper temp is high, distortion is big, is unfavorable for that cylinder sleeve is out of shape basically identical up and down and piston cooperates with cylinder sleeve at interval evenly, has hindered the further lifting of the reliability and the performance of cooling system.
The model utility content
The technical problem that the utility model will solve is; Provide a kind of and satisfying under the structural configuration prerequisite, can reasonable distribution flow to the current of upper and lower, make that to flow into cylinder body water jacket upper water flow big; It is little to flow into cylinder body water jacket bottom water flow; Thereby make that up and down flow velocity distributes rationally cylinder body, cylinder body top heat-transfer coefficient is bigger, and then make cylinder sleeve be out of shape basically identical up and down, piston cooperates the interval more even with cylinder sleeve; Improve cooling effect to reach, the cylinder body water jacket of the purpose of the Economy of optimization motor.
The technological scheme of the utility model is; The utility model cylinder body water jacket; It comprises the runner of being located in the cylinder body and moving towards around each cylinder-bore periphery and is located at the runner inlet in the cylinder body and is positioned at the current deflecting face at runner inlet rear; Also be provided with the branch fluidization tower in the runner section between said runner inlet and the current deflecting face; Divide fluidization tower to comprise top, middle part, bottom three parts; Divide between fluidization tower top wall face and the runner top wall, divide between fluidization tower middle wall face and the runner middle part wall and divide and be equipped with the interval between fluidization tower lower part wall face and the runner bottom wall, all corresponding with the runner wall with the part between the part between the middle part, middle part and the bottom in top of branch fluidization tower pastes or close-fitting mutually.
After adopting said structure, the utility model compared with prior art has the following advantages: owing to have the branch fluidization tower; And in the runner section between runner inlet and current deflecting face, and the current deflecting mask has the upwards effect of guide water stream, add on the branch fluidization tower convection current road under shunting; Will make runner middle and upper part flow rate of water flow be higher than the bottom flow rate of water flow, in the unit time, runner middle and upper part water flow will be higher than the bottom water flow; Because the shunting columniation structure is compact, the convenient layout satisfied under the structural configuration prerequisite so the utlity model has again; The current that can reasonable distribution flow to the upper and lower make that to flow into cylinder body water jacket upper water flow big, and it is little to flow into cylinder body water jacket bottom water flow; Thereby make that up and down flow velocity distributes rationally cylinder body, cylinder body top heat-transfer coefficient is bigger, and then make cylinder sleeve be out of shape basically identical up and down, piston cooperates the interval more even with cylinder sleeve; Improve cooling effect to reach, the advantage of the purpose of the Economy of optimization motor.
