AI Technical Summary
The heat dissipation effect of the existing cylinder head is poor, mainly because the heat sink is only provided on the outer wall, resulting in poor cooling effect.
Cooling channels are set between the outer walls of the intake duct, the exhaust duct, the first tappet hole and the second tappet hole, the intake duct and the first tappet hole, and the exhaust duct and the second tappet hole, and multiple heat sinks are set at these locations to increase the contact area and flow rate of the cooling air.
By increasing the contact area and flow rate of the cooling air, the heat dissipation effect of the cylinder head is significantly improved.

In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
[0026] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature.

[0027] like Figure 1-4As shown, the present invention provides a cylinder head that facilitates heat dissipation, including a main body 100. The main body 100 is provided with an intake duct 110, an exhaust duct 120, a first valve guide hole 130 provided in the intake duct 110, a second valve guide hole 140 provided in the exhaust duct 120, first tappet holes 150-150 corresponding to the intake valves, and second tappet holes 160-160 corresponding to the exhaust valves. These are all prior art and will not be described in detail here.
[0028] In this embodiment, cooling channels 170 are provided between the air intake duct 110 and the exhaust duct 120, the first push rod hole 150 and the second push rod hole 160, and the outer side walls of the air intake duct 110 and the first push rod hole 150, and the exhaust duct 120 and the second push rod hole 160, so that the outer side walls of the air intake duct 110, the exhaust duct 120, the first push rod hole 150 and the second push rod hole 160 can be in contact with the cooling air on all sides, so as to increase the contact area between the main body 100 and the cooling air, thereby achieving the purpose of improving the heat dissipation effect.
[0029] like Figure 1-4 As shown, the outer walls of the intake duct 110, the exhaust duct 120, the first tappet hole 150, and the second tappet hole 160 are all provided with a plurality of heat sinks 180. By providing the heat sinks 180, the contact area between the main body 100 and the cooling air is further increased, thereby achieving the purpose of further improving the heat dissipation effect.
[0030] like Figure 2 As shown, the first tappet hole 150 corresponds to the cooling fin 180 on the outer wall of the intake duct 110 and is connected to form a single unit. This structure not only further increases the contact area between the main body 100 and the cooling air, but also increases the cooling air flow rate by reducing the cooling channel, thereby further improving the heat dissipation effect.
[0031] like Figure 3 As shown, the second tappet holes 160 correspond one-to-one with the cooling fins 180 on the outer wall of the exhaust duct 120 and are connected to form a single unit. This structure not only further increases the contact area between the main body 100 and the cooling air, but also increases the cooling air flow rate by reducing the cooling channel, thereby further improving the heat dissipation effect.
[0032] like Figure 2 、 3As shown, the number of cooling fins 180 on the outer sidewalls of exhaust duct 120 and second tappet hole 160 is greater than the number of cooling fins 180 on the outer sidewalls of first tappet hole 150 and intake duct 110. Because the temperature of exhaust gas is higher than that of intake air, by providing more cooling fins 180 on the outer sidewalls of exhaust duct 120 and second tappet hole 160, the heat dissipation effect at exhaust duct 120 and second tappet hole 160 is improved.
[0033] like Figure 2 As shown, the number of the first tappet hole 150 and the cooling fins 180 on the outer sidewall of the intake duct 110 is three.
[0034] like Figure 3 As shown, the number of the cooling fins 180 on the outer sidewalls of the exhaust passage 120 and the second tappet hole 160 is four.
[0035] In one embodiment, the present invention further provides an engine, comprising the cylinder head described in any of the above embodiments.
[0036] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
