Description

Technical Field

[0001] This utility model belongs to the field of internal combustion engine technology, specifically relating to a cylinder block for a rotary engine. Background Technology

[0002] A rotary engine is a type of internal combustion engine. It works by burning fuel in a cavity consisting of a cylinder block, rotor, and front and rear end caps, converting the heat energy into power to drive the rotor and eccentric shaft. However, not all the heat energy from fuel combustion is converted into power; a significant portion is transferred to components such as the cylinder block and rotor. Therefore, a cooling system is needed to dissipate heat and ensure the engine operates at its optimal temperature. Currently, rotary engine cooling systems are divided into air-cooled and water-cooled systems. Air-cooled systems primarily use fins on the front and rear end caps and cylinder block shells. Cooling air blows across the fins, carrying away the heat dissipated by the engine. Air-cooled systems are mainly used in small rotary engines. Water-cooled systems primarily use water jackets on the front and rear end caps and cylinder block shells. Coolant flows through these jackets, carrying away the heat dissipated by the engine. Air-cooled systems have a simpler structure and are lighter overall, but they cannot meet the needs of high-power rotary engines. Water-cooled systems require additional components such as a water pump, radiator, and expansion tank, resulting in a more complex structure and heavier system. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems. This application proposes a cylinder block for a rotary engine, which is provided with two cylinder block water chambers to achieve water cooling. The outer surfaces of the cylinder block water chambers, heat dissipation pipes, and reinforcing ribs achieve air cooling in conjunction with a fan or airflow. Combining air cooling and water cooling improves the heat exchange efficiency of the cylinder block and enhances the cooling effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cylinder block for a rotary engine, wherein a plurality of evenly distributed cylinder block mounting holes are provided on the end face of the cylinder block, a cylinder block water chamber one is provided on one side of the cylinder block, the cylinder block water chamber one is closely attached to the cylinder block and partially surrounds it, a cylinder block water chamber two is provided on the outer side of the cylinder block water chamber one, a water inlet for installing a water inlet connector is provided at the upper end of the cylinder block water chamber one, a water outlet for installing a water outlet connector is provided at the lower end of the cylinder block water chamber two, an exhaust port is provided on the other side of the cylinder block, and an air inlet is provided above the exhaust port.

[0005] Furthermore, the first cylinder water chamber and the second cylinder water chamber are connected by multiple heat dissipation pipes, and the heat dissipation pipes are provided with two reinforcing ribs.

[0006] Furthermore, both the first and second water chambers of the cylinder are provided with reinforcing ribs parallel to the end face of the cylinder, and the reinforcing ribs are connected to the cylinder.

[0007] Furthermore, the outer arc surface of the second water chamber of the cylinder is wavy.

[0008] Furthermore, the shape of the reinforcing rib is consistent with that of the cylinder water chamber.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features two cylinder water chambers. One chamber is flush with and partially encloses the cylinder body. Cooling water flowing through the first chamber carries away heat, effectively controlling the cylinder surface temperature and maintaining a uniform overall surface temperature, thus extending the cylinder's lifespan. Multiple heat dissipation pipes connect the two cylinders. Water heated in the first chamber flows through these pipes to the second chamber, where heat exchange occurs between the pipe surfaces and the airflow. Reinforcing ribs on the pipes increase their strength and surface area for heat dissipation. The wavy, arc-shaped design of the second chamber further enhances the surface area and improves heat exchange efficiency. The outer surfaces of the second chamber, the heat dissipation pipes, and the reinforcing ribs are cooled by a fan or airflow. This invention combines water and air cooling to improve the cylinder's heat exchange efficiency and enhance cooling performance. Attached Figure Description

Detailed Implementation

[0012] To enable those skilled in the art to better understand and implement the technical solution of this utility model, the present utility model will be further described below with reference to specific embodiments. However, the embodiments described are only for illustration and are not intended to limit the present utility model.

[0013] like Figures 1-3 The cylinder block shown is for a rotary engine and includes a cylinder block 1. Several cylinder block mounting holes 2 are evenly distributed on the end face of the cylinder block 1. A cylinder block water chamber 5 is provided on one side of the cylinder block 1, which is closely fitted and partially surrounded. Cooling water can carry away the heat of the cylinder block 1 when it flows through the cylinder block water chamber 5. A cylinder block water chamber 6 is provided on the outside of the cylinder block water chamber 5 and is connected to the cylinder block water chamber by multiple heat dissipation pipes 7. Two reinforcing ribs 8 are provided on the heat dissipation pipes 7. The shape of the reinforcing ribs 8 is consistent with that of the cylinder block water chamber.

[0014] The upper end of the cylinder water chamber 5 is provided with an inlet for installing the water inlet connector 4, and the lower end of the cylinder water chamber 6 is provided with an outlet 9 for installing the water outlet connector 10. The other side of the cylinder 1 is provided with an air intake hole 12 and an exhaust hole 11 for engine air intake or exhaust, with the air intake hole 12 located above the exhaust hole 11.

[0015] Both cylinder water chamber 1 and cylinder water chamber 2 are provided with reinforcing ribs 13 that are parallel to and connected to the end face of cylinder 1. Heat from cylinder 1 can be transferred to the reinforcing ribs 13, increasing the heat exchange area between cylinder 1 and cooling water. The installation of the reinforcing ribs 13 also increases the overall strength of cylinder 1.

[0016] Preferably, the heat on the outer surface of the cylinder water chamber 6, the heat dissipation pipe 7, and the reinforcing rib plate 8 is carried away by the passing airflow, further achieving the purpose of heat dissipation. The airflow can be the wind generated by the fan or natural wind.

[0017] Working principle Cooling water enters the first type of cylinder block water chamber through the inlet connector. The water flows from the top to the bottom of the cylinder block. During this process, the cooling water exchanges heat with the outer surface of the cylinder block and the reinforcing ribs, carrying away the heat from the cylinder block. At this time, the water temperature in the first type of cylinder block water chamber rises. The cooling water flows to the second type of cylinder block water chamber through the heat dissipation pipes. The cooling water transfers heat to the heat dissipation pipes and reinforcing ribs, causing the cooling water temperature to decrease and the temperature of the heat dissipation pipes and reinforcing ribs to rise. The heat is carried away by the airflow flowing over the surface of the heat dissipation pipes and reinforcing ribs (the airflow in this process can be a fan or natural wind). The cooling water is discharged through the outlet.
