[0003] Traditional cylinder head cooling methods have certain limitations, such as insufficient cooling efficiency and heat accumulation due to unreasonable cooling structure design. With the continuous increase in engine power density, higher requirements are placed on the cooling performance of the cylinder head.
[0004] To address the issue that traditional cylinder head cooling structures are insufficient to meet the cooling requirements due to the ever-increasing power of engines, we propose a new cylinder head cooling structure. Utility Model Content
[0005] The purpose of this invention is to provide a cylinder head cooling structure that solves the problems of insufficient cooling efficiency and heat accumulation caused by unreasonable cooling structure design in traditional cylinder head cooling methods. As engine power density continues to increase, the cooling performance of the cylinder head is unable to provide effective cooling for the engine.

The mounting ring is fixedly connected to the heat dissipation channel and located above the heat dissipation channel.

[0020] This utility model provides a cylinder head heat dissipation structure, including a dual high-efficiency heat dissipation component. The dual high-efficiency heat dissipation component includes a heat dissipation channel 101, a mounting ring 105, a mounting bracket 106, heat dissipation fins 110, a fixing bracket 109, a bidirectional parallel port 102, a liquid inlet 103, a liquid outlet 104, a connecting hole 107, a mounting hole 108, a vertical hole 111, and a connecting gasket 112. This solution solves the problems of insufficient heat dissipation efficiency and heat accumulation caused by unreasonable heat dissipation structure design in traditional cylinder head heat dissipation methods. With the continuous increase in engine power density, the heat dissipation performance of the cylinder head cannot provide effective heat dissipation for the engine. It is understood that, when installation is required, workers can use bolts or special-shaped fasteners to install the entire assembly onto the engine cylinder head using the connecting hole 107 and the mounting hole 108, while simultaneously using a three-way connecting pipe to connect to the fixing bracket 109. The mounting bracket 109 provides secondary fixation to prevent loosening. During heat dissipation, the coolant is connected to the external cooling circulation system via the outlet 104 and inlet 103, allowing the coolant to enter the heat dissipation channel 101. The bidirectional openings in the bidirectional parallel port 102 effectively enhance the coolant's path, thereby improving heat exchange efficiency and increasing heat transfer between the coolant and the internal wall of the heat dissipation channel 101. Simultaneously, the heat generated is dissipated by the cooling fins 110, achieving dual heat dissipation. While retaining the original beneficial effects, this effectively solves the problems of insufficient heat dissipation efficiency and heat accumulation caused by unreasonable heat dissipation structure design in traditional cylinder head cooling methods. As engine power density continues to increase, the cylinder head's cooling performance is insufficient to provide effective heat dissipation for the engine.

When installation is required, workers will use bolts or special-shaped fasteners to assemble the components. The connecting hole 107 and the mounting hole 108 are used to mount the entire unit to the cylinder head of the engine. At the same time, the three-way connecting pipe and the fixing bracket 109 are used to fix the entire unit for a second time, thereby preventing the installation from becoming loose. When cooling, the coolant is connected to the external cooling circulation system through the outlet 104 and the inlet 103, thereby transferring the coolant into the heat dissipation channel 101 for cooling. The bidirectional opening in the bidirectional parallel port 102 effectively enhances the flow path of the coolant, thereby improving the efficiency of heat exchange and enhancing the heat exchange between the coolant and the internal wall of the heat dissipation channel 101. At the same time, the heat involved is dissipated by the heat dissipation fins 110, thus achieving dual heat dissipation.
[0022] The bidirectional parallel port 102 is fixedly connected to the heat dissipation channel 101 and is located at the internal center of the heat dissipation channel 101. The bidirectional parallel port 102 is located below the mounting bracket 106. The bidirectional opening in the bidirectional parallel port 102 will effectively enhance the flow path of the coolant, thereby improving the efficiency of heat exchange and enhancing the heat exchange between the coolant and the internal wall of the heat dissipation channel 101.
[0023] Secondly, the liquid inlet 103 is fixedly connected to the heat dissipation channel 101 and is located at one end inside the heat dissipation channel 101. The liquid inlet 103 is located below the fixing frame 109. The liquid outlet 104 is fixedly connected to the heat dissipation channel 101 and is located at one end inside the heat dissipation channel 101 away from the liquid inlet 103. The liquid outlet 104 is located on the side of the heat dissipation fins 110 away from the mounting frame 106. The liquid outlet 104 and the liquid inlet 103 are connected to the external cooling circulation system, thereby transmitting coolant into the heat dissipation channel 101 for heat dissipation.
[0024] Meanwhile, the connecting hole 107 is fixedly connected to the mounting ring 105 and is located inside the mounting ring 105. The connecting hole 107 is located on the upper part of the mounting ring 105 away from the heat dissipation fins 110. The mounting hole 108 is fixedly connected to the mounting bracket 106 and is located inside the mounting bracket 106. The mounting hole 108 is located on the upper part of the mounting bracket 106 and above the mounting ring 105. When installation is required, the operator will use bolts or special fasteners to fit the connecting hole 107 and the mounting hole 108 to place the whole unit onto the cylinder head of the engine.
[0025] In addition, the vertical hole 111 is fixedly connected to the mounting bracket 106 and is located inside the upper part of the mounting bracket 106. The vertical hole 111 is located on one side of the mounting hole 108 and is perpendicular to the mounting bracket 106. The connecting pad 112 passes through the heat dissipation fin 110 and is fixedly connected to the heat dissipation channel 101 and is located below the heat dissipation channel 101. The connecting pad 112 is also located below the heat dissipation fin 110.
[0026] When installing this utility model, workers will use bolts or special-shaped fasteners to fit the connecting holes 107 and mounting holes 108 to place the entire assembly onto the engine cylinder head. Simultaneously, a three-way connecting pipe is used to further secure the assembly to the mounting bracket 109, preventing loosening. During heat dissipation, the outlet 104 and inlet 103 are connected to the external cooling circulation system, allowing coolant to be transferred into the heat dissipation channel 101. The bidirectional openings in the bidirectional parallel port 102 effectively enhance the coolant's path, thereby improving heat exchange efficiency and increasing heat transfer between the coolant and the internal walls of the heat dissipation channel 101. Simultaneously, the heat generated is dissipated by the cooling fins 110, achieving dual heat dissipation. While retaining the original beneficial effects, this method effectively solves the problems of insufficient heat dissipation efficiency and heat accumulation caused by unreasonable heat dissipation structure design in traditional cylinder head cooling methods. With the continuous increase in engine power density, the cylinder head's cooling performance is insufficient to provide effective heat dissipation for the engine.
