Description

Technical Field

[0001] The utility model relates to the technical field of engines, and particularly relates to a high-efficiency cooling water jacket body structure. Background Art

[0002] An engine is a machine that converts energy into mechanical work. It generates power by burning fuels (such as gasoline, diesel, natural gas, etc.) or other energy sources (such as electricity). In many devices such as automobiles, airplanes, ships, and generator sets, the engine is a core component responsible for driving the vehicle or providing power.

[0003] The working principle of an engine usually involves the combustion of fuel, and this process generates a large amount of heat energy. To keep the engine operating at an appropriate temperature, avoid overheating, and ensure efficiency and lifespan, the engine must be cooled. This is where the cooling system comes into play.

[0004] The cooling water jacket is an important part of the engine cooling system. It is usually a channel made of metal (such as aluminum or cast iron), and these channels are cast or integrated into the engine block and cylinder head. The design of the cooling water jacket allows the coolant (usually a mixture of water and antifreeze) to circulate inside the engine, absorb the heat generated by the engine, and transfer the heat to the outside of the engine, and finally dissipate it through the radiator. Currently, the cooling effect of the cooling water jacket needs to be improved. Content of the Utility Model

The cooling water jacket is provided with a plurality of cylinder block accommodating cavities, and the opposite sides of each cylinder block accommodating cavity are respectively provided with a water jacket front end and a water jacket rear end.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] As Figures 1 - 5 shown, an efficient cooling water jacket body structure includes a cylinder block 1 and a cooling water jacket 2. The cooling water jacket 2 is connected to the cylinder block 1. A groove body 5 is provided on the cooling water jacket 2. A groove top wall 6 is provided in the groove body 5. A water jacket top wall 7 is provided on the cooling water jacket 2. A plurality of cylinder accommodating cavities are provided on the cooling water jacket 2. A water jacket front end 3 and a water jacket rear end 4 are respectively provided on opposite sides of the cylinder accommodating cavity.

[0023] In an optional implementation manner of the present utility model, an intake side 8 and an exhaust side 9 are provided on the cooling water jacket 2.

[0024] In an optional implementation manner of the present utility model, the intake side 8 and the exhaust side 9 are respectively located on opposite sides of the cylinder accommodating cavity.

[0025] In an optional implementation manner of the present utility model, the number of the cylinder accommodating cavities is set to four.

[0026] Implementation process:

[0027] The height of the water jacket top wall 7 in the cooling water jacket 2 is locally raised by 2 mm, increasing the capacity of the water jacket coolant. The inclination angle of the exhaust side 9 is smaller, and the inclination angle of the intake side 8 is larger. The temperature of the exhaust side 9 is high and more coolant is needed to take away the heat of the exhaust side 9. The height of the groove top wall 6 in the groove body 5 is raised by 10 mm, accelerating the flow rate of the water jacket coolant, accelerating heat exchange, and taking away more heat. The water jacket front end 3 and the water jacket rear end 4 between two cylinders are both thinned. The water jackets of each cylinder are evenly arranged to avoid the loss of coolant from the water jacket front end 3 and the water jacket rear end 4.

[0028] By improving and raising the groove top wall 6 and the water jacket top wall 7, and improving and thinning the water jacket front end 3 and the water jacket rear end 4, the present utility model can effectively avoid the loss of coolant and improve the heat dissipation effect of the cooling water jacket 2.

Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
