The following describes the detailed structure of the wind energy generator set for the vehicle. The air inlet 1 is disposed at the position of the heat dissipation port of the front face of the vehicle, and is used to guide the airflow during the running of the vehicle into the air inlet; the air inlet, the left The intake port 2 and the right intake port 3 are disposed at the current vehicle engine water tank position, and the air flow introduced from the air inlet is further introduced; the left intake chamber 4, the left intake chamber is disposed at the upper left of the front axle of the vehicle That is, the front part of the current car is installed in the left half of the engine part, and the airflow entering the intake port passes through the intake port set 2 in the left intake chamber 4; the right intake chamber 6 and the right intake chamber 6 are disposed in the vehicle The right half of the front axle, that is, the right half of the engine part is installed at the front of the car, and the airflow entering the intake port is concentrated in the right intake chamber 6 through the right intake port 3; the wind magneto unit is provided with the left wind magneto The unit 6 is disposed in the left intake chamber 6; the right wind magnet group 7, the right wind magnet unit 7 is disposed in the right intake chamber 6, wherein the left inlet 2 and the left inlet 4 are connected, and the right inlet Air passage 2 and right intake chamber 4 are connected; left exhaust passage 8, is disposed in the vehicle Left front The inside of the tire is above the tire and extends in the direction of the center line of the car, and penetrates with the left intake chamber 6; the right exhaust passage 9 is disposed above the inside of the front tire of the right side of the vehicle and extends toward the center line of the vehicle, with the right intake The left exhaust port 10 and the right exhaust port 11 are respectively disposed on the front and rear of the front and rear tires on the left and right sides of the vehicle, respectively, and are respectively connected to the left exhaust passage 8 and the right exhaust passage 9, wherein the diameters of the left and right exhaust ports are respectively Equal to or smaller than the diameter of the left and right air intakes.

Since wind energy can be converted into electric energy, in order to satisfy the need to obtain sufficient air volume and ensure the smooth running of the vehicle during the running of the vehicle, the air inlet 1 is preferentially set to be 0.8-1.4 meters long and 0.1-0.6 meters high. Rectangular opening. If the water level of the air inlet 1 is higher than the horizontal plane where the air outlets 10 and 11 are located, the vehicle is unstable due to the air volume inside the vehicle, and slight jitter occurs. Therefore, the water level of the air inlet 1 is lower than the air outlet 10 And the level of the road where 11 is located.

In order to make the airflow into the vehicle smoothly discharged from the left and right exhaust ports, but the exhaust port is too small, the air entering the car will flow out too fast, affecting the stable running of the vehicle and generating resistance, so the exhaust port is equal to or slightly smaller. The air inlet is suitable. Preferably, the diameter of the exhaust port is 0.1-0.3 meters in length and 0.1-0.6 meters in height.

Wherein, the air inlet chamber is divided into a left air inlet chamber 4 and a right air inlet chamber 7, which are disposed above the front axle of the vehicle, that is, a portion where the engine is installed at the front of the vehicle, and the airflow entering the air inlet 1 is concentrated. The intake chamber; the wind-powered magnetic units 5 and 6 are disposed in the intake chamber, and the volumes of the left and right intake chambers 4 and 7 are both 0.15-0.50 cubic meters, so that the impeller of the wind-powered magneto unit can be rotated to generate electric energy.

In order to balance the load of the vehicle, the wind magneto unit includes a left wind magneto unit and a right wind magneto unit, and the left and right splits are divided by the vehicle center line, wherein the number of left wind magnets The same number as the right wind magneto. When the vehicle is manufactured, a plurality of, for example, eight wind magnetic motors may be disposed on the left and right sides of the vehicle center line, but several of the eight wind magnetic motors may be controlled by the circuit of the automobile, so that the energy output can be well controlled. Avoid energy waste.

In order to eliminate this effect due to the influence of the airflow entering the vehicle on the stable running of the vehicle during driving, except that the intake passage is set to the left and right intake passages, the intake chamber is set to the left and right intake chambers, and the wind magnetic current The unit is arranged outside the left and right wind magneto, the exhaust duct also includes a left exhaust passage and a right exhaust passage, the left exhaust passage and the left intake chamber are connected, and the right exhaust passage and the right intake passage are connected.

The volume of the left and right intake passages is 0.04 - 0.50 cubic meters, and the volume of the left and right exhaust passages is 0.04 - 0.50 cubic meters, so as to better discharge the airflow into the vehicle from the left and right exhaust ports.

The working principle of the wind energy generator set of the invention is to utilize the natural wind and the strong wind generated by the automobile during the driving process, and the wind is introduced into the left and right air intake chamber through the left and right air inlets through the air inlet, and the air quickly enters through the air inlet. Pushing the wind-magnet unit impellers in the left and right intake chambers to generate electric energy for the car to drive, and storing excess electric energy in the battery to ensure the starting and continuous running of the car, and the airflow pushes the impeller to rotate, even when the car stops. , can still push the impeller to rotate, thus ensuring the energy required for the vehicle to run continuously.

The height is 0.5, the inlet area is 0.5 ² , regardless of air compression and air flow rate, empty The density of the gas is 1.293kg/m ³ , then according to the flow formula, the current flow rate into the inlet is: m = pvA = 1.293x ^40xl ° χθ.5 = 1 AS kg / s

3600 assumes that the speed is

, according to the flow calculation formula, the current airflow into the air inlet is: m = vA = 1.293x(vl + v2)x0.5

= 10.41^/*

When the airflow enters a channel, its flow rate is constant. However, due to the different cross-sectional area in the channel, the airflow velocity is different on different sections. For details, see the following formula: m = p ₁ v ₁ A ₁ = p ₂ v ₂ A ₂ is the flow rate, ^ is the density of the gas, V is the flow rate of the gas, and A is the area of the section.

32.2m I s

pA 1.293 x 0.5x 0.5 In this embodiment, the principle of power generation is to use the wind to push the impeller to rotate, to convert the kinetic energy of the wind into the kinetic energy of the impeller, and then to convert the kinetic energy of the impeller into electrical energy. At this time, the air flow rate pushes the impeller to rotate. The density of the air is P, the length of each impeller is L, the horizontal wind speed of the impeller is V, the efficiency of the whole generator is η, the length of the impeller is L, then the impeller The sweeping area is S = L2. The air mass passing through the impeller swept area in time t is m=PSvt, and the total kinetic energy of these air is E=l/2mv2=l/2pSvtv2, and the electric power generated by each generator P =E
