Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technological scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to shown in Figure 2; The said device of the utility model specifically comprises: engine body, engine cylinder cover 9 and secondary water cavity 8, and said secondary water cavity 8 is provided with secondary water cavity water intake 7, is provided with the cylinder sleeve structure in the said engine body; Gap between engine body and the cylinder sleeve is called as the body water jacket; Said body water jacket comprises body water jacket top 5 and body water jacket bottom 6, is provided with wall between body water jacket top 5 and the body water jacket bottom 6, and said wall is provided with permeable hole; Said permeable hole is used to realize the circulation of the cooling liquid between body water jacket top 5 and the body water jacket bottom 6, is provided with string water hole 4 between said engine body water jacket and the engine cylinder cover 9; First water intake, 1, the first water intake 1 connects body water jacket top 5 and secondary water cavity 8, is arranged on the adjacent face of body water jacket top 5 and secondary water cavity 8; Second water intake, 2, the second water intakes 2 connect body water jacket bottoms 6 and secondary water cavities 8, are arranged on the adjacent face of body water jacket bottom 6 and secondary water cavity 8; Get into the cooling liquid on body water jacket top 5 and the cooling liquid of entering body water jacket bottom 6 and accomplish after the cooling, through string water hole 4 entering cylinder caps 9.
Body water jacket top 5 is 1:1 with body water jacket bottom 6 division proportion in the present embodiment.
In the utility model; Cooling liquid gets into after the secondary water cavity 8 from secondary water cavity water inlet 7; Logical respectively first water intake 1 and second water intake 2 get into body water jacket top 5 and body water jacket bottom 6; 5 respectively form a circulation water jacket with body water jacket bottom 6 on body water jacket top, and cooling liquid in the body water jacket top 5 realizes getting into cylinder caps 9 through the string water hole 4 that connects body and cylinder cap 9 after the cooling of body upper, after the cooling of cooling liquid realization to underpart in the body water jacket bottom 6; Get into body water jacket top 5 through the permeable hole on the wall between body water jacket top 5 and the body water jacket bottom 6 earlier, get into cylinder cap 9 through string water hole 4 again.
In specific embodiment, because the heat load of body upper is bigger, institute is so that the cross section of first water intake 1 greater than the cross section of second water intake 2, increases the flow of body upper cooling liquid, with the cooling effect of assurance body upper.
In addition, first water intake 1 and second water intake, 2 one side internal faces are skewed, and the angle of inclination preestablishes.In specific embodiment, be advisable, under the prerequisite that does not influence overall plan, also can select other angles as required with 30 °.When cooling liquid is passed through first water intake 1 and second water intake 2; Because there is the tilt angle in above-mentioned two water intakes, one side inwall; So the cooling liquid after flowing out is directed deflection left side or right side, said tilt internal wall plays the effect that drainage is led to the cooling flow that gets into engine body, and cooling liquid can be rotated around body; Thereby make cooling effect more even, the generation of mode cavitation pitting phenomenon.With reference to shown in Figure 3; Fig. 3 is the top cross-sectional view of water intake; Wherein dash area is represented the engine body surface adjacent with secondary water cavity, and first water intake 5 and second water intake 6 all are arranged on this surface, this surface is divided into two-part trapezoidal space promptly represents water outlet; Because first water outlet 5 is identical with second water outlet, 6 situation, so in this unified explanation; Because said water outlet one side inwall is inclination, so the section shape of overlooking of water outlet is a right-angled trapezium, trapezoidal hypotenuse is a side inwall of said inclination; This surface is the engine body water jacket with top, is secondary water cavity with the bottom; Cooling liquid is through after the water intake, according to the direction deflection of arrow sign; Need to prove that the direction of arrow of painting only shows the roughly trend of coolant flow, be intended to describe clearly the thinking of this partial design, certain deviation may take place in the trend of liquid under the actual conditions under the constant situation of general direction.
In the present embodiment; Secondary water cavity 8 further is provided with a connection mouth 3, is communicated with string water hole 4, because string water hole 4 itself connects engine body and engine cylinder cover 9; So through connection mouth 3, realize that three between secondary water cavity 8, engine body and the engine cylinder cover 9 are connected.Through connection mouth 3, make the cooling liquid shunting part in the secondary water cavity directly get into engine cylinder cover 9, thereby improve the cooling effectiveness of engine cylinder cover 9.
With reference to shown in Figure 4; In conjunction with above technological scheme, the route of flowing through of cooling liquid is following in the said device of the utility model: cooling liquid gets into secondary water cavity 8, and the cooling liquid in the secondary water cavity is split into three parts; A part gets into body water jacket top 5 through first water intake 1; A part gets into body water jacket bottom 6 through second water intake 2, and a part gets into string water hole 4 through connection mouth 3, gets into cylinder cap 9 through string water hole 4 again; The cooling liquid that gets into body water jacket top 5 gets into cylinder cap 9 through string water hole 4 again with the cooling liquid that gets into body water jacket bottom 6.
With reference to shown in Figure 5, the said engine device of the utility model, concrete working method is following in cooling procedure:
S1, cooling liquid get into secondary water cavity 8 through secondary water cavity water intake 7, and the cooling liquid in the secondary water cavity 8 gets into body water jacket top 5 from first water intake 1; Cooling liquid second water intake 2 corresponding from the second water outlet position gets into body water jacket bottom 6;
The cooling liquid on s2, entering body water jacket top 5 is 5 formation circulation on body water jacket top, and body upper is cooled off; The cooling liquid of entering body water jacket bottom 6 is 6 formation circulation in body water jacket bottom, and underpart is cooled off;
The cooling liquid on s3, entering body water jacket top 5 is accomplished after the cooling, gets into cylinder caps 9 through string water hole 4;
The cooling liquid of s4, entering body water jacket bottom 6 is accomplished after the cooling, gets into cylinder caps 9 through string water hole 4.
The cooling liquid of said entering body water jacket bottom 6 is accomplished after the cooling; Getting into cylinder cap 9 through string water hole 4 is specially; After getting into the cooling liquid completion cooling of body water jacket bottom 6; Permeable hole through wall between body water jacket top 5 and the body water jacket bottom 6 gets into body water jacket top 5,5 gets into cylinder caps 9 through string water hole 4 from body water jacket top again.
Also comprise in the present embodiment: the cooling liquid in the secondary water cavity 8 directly gets into string water hole 4 through connection mouth 3, gets into cylinder cap 9 through string water hole 4 again.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
