Description

Technical Field

[0001] This utility model relates to the field of diesel engine cooling technology, and in particular to a high-efficiency cooling single-cylinder air-cooled diesel engine. Background Technology

[0002] Single-cylinder air-cooled diesel engines use a high-speed rotating cooling fan (usually mounted on the flywheel end) to force external air onto the heat sink, carrying away heat. The airflow generated by the fan is concentrated and directed to the heat sink of the cylinder through a shroud, ensuring that key high-temperature components are effectively cooled. However, with the development of technology and the demands of use, single-cylinder air-cooled diesel engines have seen significant improvements in both efficiency and size. Correspondingly, air cooling also faces greater technical challenges, requiring more efficient heat dissipation to adapt to the technological changes in single-cylinder air-cooled diesel engines.

[0011] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] according to Figures 1-3 As shown, a high-efficiency heat-dissipating single-cylinder air-cooled diesel engine includes a diesel engine housing 1. A cylinder end 2 is disposed on the top of the diesel engine housing 1, and a cylinder head 3 is disposed on the cylinder end 2. A flywheel 4 is disposed on one side of the diesel engine housing 1, and the side of the diesel engine housing 1 with the flywheel 4 is configured as the mounting side of the air guide shroud. Vertical heat sinks 5 and horizontal heat sinks 6 are disposed on the cylinder end 2. The vertical heat sinks 5 are vertically arranged around the cylinder end 2, and the horizontal heat sinks 6 are disposed above the vertical heat sinks 5 and are arranged vertically and sleeved on the cylinder end 2. An intake end 31 and an exhaust end 32 are disposed on the cylinder head 3. End cap heat sinks 7 are disposed around both the intake end 31 and the exhaust end 32. Air intake channels 8 are also provided on both sides of the end cap heat sinks 7 on the cylinder head 3.

[0014] The vertical heat sink 5 is provided with a plurality of ventilation holes 61, which are located at positions corresponding to the gaps between the vertical heat sinks 5, and are located on the mounting side of the air guide shroud.

[0015] On both sides of the vertical heat sink 5, there are also air guide blocks 62. The air guide blocks 62 are set in a rhomboid structure, and their tilt angle points to the outer wall of the cylinder end 2.

[0016] The bottom of the diesel engine housing 1 is also provided with a support base 9, and a support heat sink 10 is provided between the support base 9 and the bottom of the diesel engine housing 1. The support heat sink 10 is arranged at the bottom of the diesel engine housing 1 and is designed with a wave-shaped structure. The wave-shaped structure can increase the support area of ​​the support heat sink 10 and maximize the support effect while maintaining the heat dissipation function.

[0017] In practical application, a wind deflector is installed on the side with the flywheel. The wind deflector concentrates the airflow generated by the fan and guides it to the vertical heat sink 5 and the horizontal heat sink 6 on the cylinder end 2. The airflow in the vertical heat sink 5 then enters the horizontal heat sink 6 through the ventilation hole 61. The additional airflow increases the speed of the airflow into the heat sink 6, improving the heat dissipation efficiency. At the same time, the air guide block 62 in the horizontal heat sink 6 guides the incoming airflow to the outer wall of the cylinder end 2, improving the heat dissipation effect. In addition, the airflow from the uppermost layer of the horizontal heat sink 6 and a portion of it through the ventilation hole 61 enters the end cover heat sink 7, improving the heat dissipation effect of the exhaust end 32 on the cylinder head 3. Then, the airflow reaches the end cover heat sink 7 at the intake end 31 through the air intake channels 8 on both sides for heat dissipation. During the air deflector's guidance, a portion of the airflow is also guided to the bottom of the diesel engine housing 1 and then into the supporting heat sink 10. The bottom of the diesel engine housing 1 is equipped with an oil sump bottom shell, and the supporting heat sink 10 can dissipate the engine oil in the oil sump bottom shell.

[0018] This design is ingenious. The coordinated arrangement of vertical and horizontal heat sinks significantly improves the heat dissipation efficiency of the single-cylinder air-cooled diesel engine, increases airflow velocity, and thus enhances overall heat dissipation performance. The design of the air guide block effectively directs airflow to the outer wall of the cylinder end, ensuring that critical high-temperature components are adequately cooled. The configuration of the end cover heat sink and air intake channel optimizes the heat dissipation effect of the cylinder head, further improving equipment performance. In addition, the supporting heat sink effectively dissipates heat from the bottom oil tank shell of the diesel engine housing, enhancing the stability and durability of the equipment.

[0019] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
