Embodiment Construction

[0020] The core of the invention is to provide a cylinder head cooling water chamber to improve the cooling effect of the cylinder head.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Such as Figure 1-Figure 4 As shown, the present invention discloses a cylinder head, including a cooling water chamber, wherein the cooling water chamber is divided into an upper water chamber 1 and a lower water chamber 2 by a partition, and the partition has a The cooling liquid in the chamber 2 is ...

Abstract

The invention discloses an air cylinder cover. The air cylinder cover comprises a cooling water cavity, wherein the cooling water cavity is divided into an upper-layer water cavity and a lower-layer water cavity by the aid of a separating plate; and a water hole for guiding a cooling liquid in the lower-layer water cavity into the upper-layer water cavity is formed in the separating plate and can guide the cooling liquid in the upper-layer water cavity. The cooling water cavity of the cylinder cover is divided into the upper-layer water cavity and the lower-layer water cavity which are separated by the separating plate, all water flow flows through a lower bottom plate, the cooling effect of a fire plate is enhanced, and meanwhile, auxiliary effects of enhancing the rigidity and the strength of the cylinder cover are also realized; the cooling liquid performs cooling from bottom to top via the water hole, so that the water passing area is increased, and the cooling effect of a bridge zone is enhanced; and the flow direction of the cooling liquid can be adjusted through guidance of the water hole, thus, more cooling liquid flows to the area required to be cooled, and the cooling effect is further improved. The invention further discloses an air cylinder comprising the air cylinder cover.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a cylinder and a cylinder head thereof. Background technique [0002] As an important part of the engine, the cylinder head is used to seal the gas and form a combustion space together with the piston. The working environment is extremely harsh, and due to the action of high temperature and high pressure gas, the thermal stress and mechanical stress are very large. [0003] With the upgrading of diesel engine emissions, the degree of strengthening and power requirements increase, the cooling efficiency of the traditional cylinder head cooling water cavity structure is low, and the thermal load of the cylinder head cannot be effectively reduced. [0004] Therefore, how to provide a cylinder head cooling water cavity to improve the cooling effect of the cylinder head is a technical problem to be solved by those skilled in the art. Contents of the invention [0005] In view of t...
