The present invention can also be: steam drive apparatus can be fan blade, and the water vapor that steam (vapor) outlet is discharged is directly aimed at fan blade, and fan blade drives generator for electricity generation.
Fan blade generator can adopt common generator, in its rotating shaft leaf blade is installed, and then is dynamically charged to storage battery.
A kind of engine exhaust heat utilizes method, it adopts the spray mode that the cylinder in the engine cooling water jacket is cooled off, the steam that is produced is sent from engine cooling water jacket, generate electricity by steam drive apparatus, to storage battery power supply, when realizing, the kinetic energy of the steam that produces is converted into electric energy to the cylinder cooling.
A kind of engine exhaust heat utilizes system, comprise engine cylinder and be arranged on the external cooling jacket of cylinder, a plurality of shower nozzles are set on the described cooling jacket, each shower nozzle connects water tank by water pump, cooling jacket is provided with steam (vapor) outlet, steam (vapor) outlet connects steam drive apparatus, and steam drive apparatus connects generator, and generator connects storage battery.
Described steam drive apparatus is a turbo machine, and the impeller of turbo machine connects alternator shaft.
Described steam drive apparatus is a fan blade, and fan blade connects alternator shaft, and fan blade is provided with the housing of concentrating steam outward.
Described shower nozzle is arranged on the cooling jacket top, makes the water of ejection spray the cylinder external surface from top to bottom.
Described shower nozzle is arranged on the cooling jacket sidepiece.
Described steam (vapor) outlet is arranged on the side-lower or the below of cooling jacket.Be convenient to the condensed water discharging.
The invention has the beneficial effects as follows:
Engine exhaust heat of the present invention utilizes system to save cooling liquid and corresponding liquid circulation parts, helps reducing the overall volume of engine system.The present invention really accomplishes making full use of of waste heat, and a large amount of waste heats are driven generator for electricity generation by steam, produces considerable electric energy.
Method of the present invention and system thereof are particularly useful for the automobile of oil electric mixed dynamic, the steam kinetic energy that the cooling automobile motor is produced constantly dynamically is converted into electric energy and charges to car accumulator, can exempt the construction at hybrid vehicle special charging station, thereby can save the resource input greatly, help the fast development of oil electric mixed dynamic automobile, meet the international trend of energy-saving and emission-reduction.
