Example 1:
a self-cooling automobile engine is basically shown in figure 1 and comprises an engine shell 1 and a power output part arranged in the engine shell 1, wherein the power output part of the engine is of an existing structure, and therefore details are not repeated. A cooling channel 2 is arranged in the engine shell 1, and the cooling channel 2 is positioned above the engine shell 1; both ends of the cooling channel 2 penetrate through the engine shell 1 and are communicated with the outside, and a filter screen is arranged in the air inlet end (namely the left end) of the cooling channel 2.

The cooling channel 2 and the flow guide block 3 form an air amplifier structure through arrangement of the structure.
The cooling section 22 includes a leading-in section, a throat section and a diffuser section which are sequentially communicated from left to right, and the inner diameter of the throat section is smaller than the inner diameters of the diffuser section and the leading-in section, so that the cooling section 22 forms a venturi tube structure. The side wall of the engine housing 1 is provided with a cooling flow channel 11, the cooling flow channel 11 is spirally arranged, the left side of the cooling flow channel 11 is communicated with the outside, the right end of the cooling flow channel 11 is communicated with a suction pipe 221, and one end of the suction pipe 221, which is far away from the cooling flow channel 11, is communicated with the throat section of the cooling section 22.
The outer wall of the cooling section 22 is provided with a plurality of heat conduction bumps 222, and the heat conduction bumps 222 penetrate through the cooling section 22 and extend into the cooling section 22. The inner wall of the cooling section 22 is fixed with a rotating impeller 223, and after the air flow enters the cooling section 22, the rotating impeller 223 is impacted, so that the rotating impeller 223 rotates, and the cooling section 22 is driven to rotate. The left end of the cooling section 22 is rotatably connected with the flow guide block 3, and the right end of the cooling section 22 is rotatably connected with the engine shell 1. A radiator fin 224 is fixed to a portion of the right end of the cooling section 22 outside the engine case 1.
The top of the engine housing 1 is also rotatably connected with a vertically arranged rotating shaft 4, a turbofan 41 is fixed at the rotating top end, and a semicircular driving wheel 42 is further fixed on the rotating shaft 4. The left and right sides that the engine top is located pivot 4 all is fixed with aeration bucket 5, and aeration bucket 5 is towards the equal opening of one end of pivot 4, and equal lateral sliding connection has piston 51 in the aeration bucket 5, and open-ended one side welding is kept away from to piston 51 has the spring, and the one end welding that piston 51 was kept away from to the spring is on aeration bucket 5. The side of the piston 51 close to the opening is fixed with a push rod 52, and when the driving wheel 42 rotates, the push rod 52 can be intermittently abutted and the push rod 52 is pushed to move.

An air outlet one-way valve is arranged in the air outlet 54, and when the piston 51 slides towards the closed end of the air charging barrel 5, the air in the air charging barrel 5 is extruded, so that the air in the air charging barrel 5 is discharged through the air outlet 54. The air outlet 54 is also communicated with an air duct 55, and one end of the air duct 55 far away from the air outlet 54 is communicated with the diversion cavity 31. The gas flow in the gas outlet pipe per unit time is larger than the gas flow among the pressurizing channel units.
The specific implementation process is as follows:
in the running process of the automobile, gas flows around the engine, so that the gas can impact the turbofan 41, the turbofan 41 rotates, and the driving wheel 42 is driven to rotate through the transmission of the rotating shaft 4. When the driving wheel 42 rotates, the push rods 52 on both sides are intermittently pressed, so that the push rods 52 drive the pistons 51 to move. When the piston 51 slides and extrudes the gas in the gas adding barrel 5, the gas is guided into the guide cavity 31 in the guide block 3 through the gas outlet 54 and the gas guide pipe 55 and then flows into the cooling channel 2 through the annular channel 32 and the pressurizing channel.
An air amplifier structure is formed between the flow guide block 3 and the cooling channel 2, and the gas flow of the gas guide pipe 55 in unit time is larger than that of the pressurizing channel in unit time, so that the air inflow in the obtained flow guide cavity 31 is larger than the air outflow, and the gas enters the cooling channel 2 at high pressure and high speed. According to the operation principle of the air amplifier, the air inlet section 21 of the cooling channel 2 can rapidly suck air, a large amount of external air flows along the cooling channel 2, heat exchange with internal air and parts of the engine is realized, and then the temperature reduction of the engine is completed. This approach achieves engine cooling without the use of externally introduced coolant.
When the gas flows through the cooling section 22, the cooling section 22 forms a venturi structure, and the gas is sucked through the throat section and the suction pipe 221, so that the external gas is sucked through the cooling flow passage 11, and the gas flows along the cooling flow passage 11 of the engine case 1, thereby cooling the engine case 1.
Meanwhile, when the gas enters the cooling channel 2, the gas impacts the rotating impeller 223, so that the cooling section 22 rotates, the heat-conducting bump 222 rotates to absorb the heat of each part, and then the gas in the cooling channel 2 flows to dissipate the heat, thereby improving the cooling effect.
When the cooling section 22 rotates, the cooling fins 224 are also driven to rotate, so that the air flow around the engine is improved, and the heat dissipation effect of the engine is further improved.
Example 2:
The top of the sliding plate is fixed with a driving rod 81, the driving rod 81 on the left side penetrates through the bottom of the liquid storage tank 6 and is in vertical sliding connection with the liquid storage tank 6, and the other driving rod 81 penetrates through the bottom of the rotating shaft 4 and is in rotating connection with the rotating shaft 4; the rotating shaft 4 is vertically connected with the engine shell 1 in a sliding mode.
The specific implementation process is as follows:
when the coolant in the liquid storage tank 6 is sufficient, the floating plate 7 moves up under the action of the buoyancy of the coolant, so that the sliding plate on the left side moves up, and then the driving rod 81 is driven to move down by the sliding plate on the left side according to the flowing driving of the communication liquid, so that the rotating shaft 4 moves down, the driving wheel 42 is separated from the push rod 52, and when the rotating shaft 4 rotates, the push rod 52 cannot be pushed, so that the cooling channel 2 cannot run. The engine is cooled by flowing of the cooling liquid.
When the coolant in the reservoir 6 is used up or is about to be used up, the coolant is less, and therefore the effect of lowering the temperature of the engine is reduced. At this time, the buoyancy received by the floating plate 7 is also reduced, so that the floating plate 7 moves down and presses the left driving lever 81, so that the left slide plate moves down. When moving downwards, the sliding plate can extrude the communication liquid, so that the sliding plate on the right side drives the driving rod 81 on the right side to move upwards, the rotating shaft 4 is driven to move upwards, the driving wheel 42 is abutted against the push rod 52, gas can be introduced into the flow guide block 3 by the gas adding barrel 5, a large amount of gas can flow in the cooling channel 2, and the engine can be cooled.
With the arrangement of the structure of embodiment 2, when the coolant is sufficient, the temperature can be lowered only by the coolant. When the cooling liquid is insufficient, a large amount of gas flows in the cooling channel 2 to exchange heat with the interior of the engine, so that the temperature of the engine is reduced, and the probability of damage of the engine caused by long-term high-temperature state is reduced.
It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
