Embodiment
[0023] This embodiment discloses a water-cooled and adjustable electromagnetic sealing device for a micro-rotor engine. The coolant channel is two channels above and below the cylinder 8, and the inner cavity around the cylinder 8 is circular or elliptical. Among them, the coolant channel opening near the cylinder exhaust port 6 is the lower coolant inlet 1 and the upper coolant inlet 3 , and the lower coolant outlet 2 and the upper coolant outlet 4 are near the air inlet 5 . The spiral wires 7 are arranged in the two cooling liquid passages, and the top of the sealing sheet 10 in the rotor 9 is attracted to be in close contact with the inner wall of the cylinder 8 through the magnetic force generated by the current coil.
[0024] When the rotary engine starts to work, the cooling water is passed into the coolant channel of the cylinder 8 through the water pump, and enters the thermostat and the water radiator after flowing through the coolant channel of the cylinder 8, in orde...

The invention discloses a water-cooling and adjustable electromagnetic sealing device for a micro rotor engine, relates to a device combining water cooling and electromagnetic sealing and used for the micro rotor engine, and belongs to the field of micro rotor engines. Cooling liquid channels symmetrically distributed in the upper and lower sides are formed in a cylinder of the micro rotor engine, and the shapes of the cooling liquid channels adapt to the shape of the inner wall of the cylinder in order to guarantee uniform magnetic force. Wires good in insulating performance are installed in the cooling liquid channels, a magnetic field is generated when direct current is introduced into the wires, the magnetic field attracts a sealing piece on a rotor to make close contact with the inner wall of the cylinder, and electromagnetic sealing is achieved. The cooling effect is adjusted by adjusting the flow speed of cooling liquid, and the magnitude of sealing attraction force is adjusted by adjusting the magnitude of the current of the wires. The heat dissipation problem and the sealing problem of the rotor engine can be improved, and the problems that due to thermal fatigue damage of a rotor engine cylinder, efficiency is reduced and the service life is shortened are solved.
Description
technical field [0001] The invention relates to a water cooling and electromagnetic sealing device for a micro-rotor engine, in particular to a device combining water cooling and electromagnetic sealing, which belongs to the field of micro-rotor engines. Background technique [0002] With the development of micro-electro-mechanical systems (MEMS), the development of micro-energy systems with small volume, light weight, high energy density, and continuous operation has become the focus of attention in various countries. Compared with conventional power supply equipment, micro-engines use hydrocarbons as fuels, and their energy density is higher than that of battery systems. Due to the development of fuel diversification, they also have the potential for low cost. Therefore, micro-engines will have a wide range of application prospects in electronic devices in various industries such as industry, agriculture, environmental protection, and medical care. [0003] The current re...
