Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 3, according to the cylinder head of the V-type diesel of the utility model embodiment, this V-type diesel is installed two identical cylinder head, cylinder head comprises that cylinder head body 1 and the guide plate 2(with breach 21 are referring to Fig. 4), cylinder head body 1 inside has cooling water chamber (referring to Fig. 6 or Fig. 7), the front end of cylinder head body 1 is provided with front end water outlet 12, front end water outlet 12 has flanged surface 121, flanged surface 121 vertical with the bottom surface of cylinder head (referring to Fig. 2), the rear end of cylinder head body 1 is provided with rear end water outlet 11, rear end water outlet 11 is positioned at the end face (referring to Fig. 1) of cylinder head, front end water outlet 12 and rear end water outlet 11 connect (referring to Fig. 6 and Fig. 7) with cooling water chamber, front end water outlet 12 and rear end water outlet 11 and the 1 integrally casting moulding of cylinder head body, strengthen cylinder head intensity, rigidity.This cylinder head is arranged on respectively after V-type diesel, the cooling water of two cylinder head flows out by front end water outlet 12 and rear end water outlet 11 respectively, form thus cylinder head in V-type diesel with cylinder cap different cooling water flows to, and then can cancel outfall sewer, can make V-type diesel integral layout simply compact, cost-saving.Guide plate 2 with breach 21 is located in cylinder head ridge area 3(referring to Fig. 4) cooling water chamber in, notched guide plate 2 is divided into current region, upper strata 31 and lower floor's current region 32(referring to Fig. 3 by the cooling water chamber of cylinder head ridge area), notched guide plate 2 can forcibly changing be positioned at the flow direction of the cooling water of cylinder head ridge area 3, strengthens current and improves the cooling effect to ridge area after oppositely.
