Description
Technical field
This utility model relates to engine component field, specifically a kind of uniflow type cylinder body water jacket.
Background technology
nullBlock jacket be engine interior be that engine hot parts is lowered the temperature the coolant circulation passage that designs，Coolant circulates the effect reaching heat radiation in water jacket，The circulation of coolant is had a very big impact by the structure of water jacket，Existing engine coolant endless form is: first，The pump handle coolant water inlet from cylinder block front end is pressed into and enters in the annular channel of cylinder holes setting and coolant shunts to both sides in annular channel porch thus cools down cylinder body both sides respectively，Therefore，In existing electromotor，Coolant is after entering annular channel，First cooling is near the cylinder of water inlet，Other cylinder is cooled down according still further to order，During this coolant circulates，When there is no cooling cylinder below，Part coolant is directly entered cylinder head jacket，The coolant flowing through cylinder rearward so can be caused fewer than forward cylinder，Coolant rate is uneven，Cooling effect is bad，On the other hand，Owing to coolant will shunt to runner both sides after the runner entering annular，Thus considerably reduce flow velocity and the hydraulic pressure of coolant，And then reduce cooling effect；
Therefore, for solving problem above, need a kind of can making by the coolant rate of each cylinder holes sidewall in cylinder body more uniformly, the uniflow type cylinder body water jacket of cooling liquid speed and pressure can be effectively improved again simultaneously.
Utility model content
In view of this, the purpose of this utility model is to overcome defect of the prior art, it is provided that a kind of can making by the coolant rate of each cylinder holes sidewall in cylinder body more uniformly, can be effectively improved again the uniflow type cylinder body water jacket of cooling liquid speed and pressure simultaneously.
Uniflow type cylinder body water jacket of the present utility model, the water inlet including the annular channel arranged around each casing bore and connected with described annular channel in being arranged at cylinder body and outlet, be provided with the orifice plug hindering coolant flow to form it into one-way circulation in described annular channel；Coolant is after water inlet flows into water annulus, a runner of coolant has been blocked owing to being provided with orifice plug in water annulus, make the coolant can only be around the unidirectional runner of annular channel (i.e. flowing clockwise or counterclockwise around annular channel), owing to a part of coolant needs to flow through just to enter in cylinder cover water jacket by water hole away from after the cylinder body of inlet end, therefore, can make by the coolant rate of each cylinder holes sidewall in cylinder body the most uniform, improve the cooling effect away from water inlet side cylinder body, on the other hand, owing to orifice plug reduces the flow cross-section areas of annular channel, therefore, coolant flow velocity in annular channel and hydraulic pressure can be increased substantially, thus improve the cooling effect of cylinder body further；
Further, described orifice plug is arranged in described annular channel and retrains coolant one-way flow near water inlet, therefore, after coolant is entered into annular channel by water inlet, change is flowed to by the coolant flowing to orifice plug side, it is ensured that coolant is around annular channel one-way flow；
Further, water space was formed between the upper and lower two ends of described orifice plug and annular channel inwall, after coolant enters into water annulus by water inlet, a small amount of coolant enters into orifice plug opposite side and in water hole enters into cylinder cap by crossing water space, the path flowing through cylinder body due to this part coolant is shorter, therefore its temperature is relatively low both entered in cylinder cap, and then improve the cooling effect of cylinder cap.
Further, the orifice plug installing hole and this orifice plug installing hole that are communicated with described annular channel on the faying face of described cylinder body are bellmouth, the faying face of cylinder body described herein be cylinder body with cylinder cap be fitted to each other face, can easily orifice plug be inserted in annular channel by this orifice plug installing hole, this installing hole being set to bellmouth be easy to make orifice plug fix with cylinder body, orifice plug will be carried out spacing to reserve water space by the conical inboard wall of this installing hole simultaneously.
Further, described orifice plug includes cylindric plug core and is wrapped in the cone rubber set outside plug core, plug core can use metal bar to make, cone rubber set can coordinate with the orifice plug installing hole of taper, thus forming preferable sealing function, plug core two ends are all stretched out cone rubber set thus were formed water space.
Uniflow type cylinder body water jacket of the present utility model also includes the multiple water holes being arranged at cylinder liner and connecting with described water annulus, cylinder cap can be cooled down in entering into cylinder cap by water hole by the coolant in annular channel, the flow direction of described water hole annularly water channel is distributed and is positioned at the water hole cross section cross section less than the water hole being positioned at annular channel downstream of annular channel upstream, this arrangement can make the coolant cooling in water annulus less away from flow loss before the cylinder of water inlet, ensure the most uniform by the coolant rate of each cylinder holes sidewall in cylinder body, improve the cooling effect away from water inlet side cylinder body.
Further, described water hole includes the circular hole that connects with described annular channel upstream and the waist-shaped hole with described annular channel communicating downstream；Use waist-shaped hole that the flow cross-section areas of water hole on the premise of not increasing annular channel width, can be effectively improved as water hole, increase the flow of the water hole being positioned at annular channel downstream.
The invention also discloses a kind of engine cylinder-body, described uniflow type cylinder body water jacket is arranged at this engine cylinder-body.
The beneficial effects of the utility model are: uniflow type cylinder body water jacket of the present utility model, coolant is after water inlet flows into water annulus, a runner of coolant has been blocked owing to being provided with orifice plug in water annulus, make the coolant can only be around the unidirectional runner of annular channel (i.e. flowing clockwise or counterclockwise around annular channel), owing to a part of coolant needs to flow through just to enter in cylinder cover water jacket by water hole away from after the cylinder body of inlet end, therefore, can make by the coolant rate of each cylinder holes sidewall in cylinder body the most uniform, improve the cooling effect away from water inlet side cylinder body, on the other hand, owing to orifice plug reduces the flow cross-section areas of annular channel, therefore, coolant flow velocity in annular channel and hydraulic pressure can be increased substantially, thus improve the cooling effect of cylinder body further.
