The operation principle of above-mentioned two kinds of existing ignition coils is: first, and ECU orders about switch 3 and closes, and vehicle power 1 connects primary coil 21.Now, will increase from zero to a stationary value by the electric current (i.e. primary current) of primary coil, this stationary value determined by the magnitude of voltage of vehicle power 1 and the resistance value of primary coil 21.Along with primary current increases, the electromagnetic energy that primary coil 21 produces is stored in iron core 23.When primary current reaches certain value (this certain value≤stationary value), ECU orders about switch 3 and disconnects instantaneously, decaying rapidly in the magnetic field that the electric field sudden change of primary coil loops causes primary coil 21, thus induces high-tension electricity kinetic potential at the two ends of secondary coil 22.Space (being called spark plug 4 conducting) between two electrodes of this high-tension electricity kinetic potential disruptive spark plug 4, produces electric arc with igniting.
Existing ignition coil is when normally working, and internal temperature is at about 170 DEG C, and ambient temperature is at about 90 DEG C.Be in the useful life that hot environment can shorten ignition coil for a long time, increase fault occurrence probability.

Embodiment
Heat transfer generator is a kind of device using Seebeck effect (Seebeck effect) temperature difference to be directly changed into electric energy, and conversion efficiency is roughly about 5% ~ 8%.Early stage heat transfer generator uses two kinds of metal material contacts to be formed usually, and heat transfer generator of today uses p-type semiconductor material to contact formation with n-type semiconductor usually.
Refer to Fig. 2, this is a kind of principle schematic of heat transfer generator, one end of p-type semiconductor and n-type semiconductor is combined, this binding end is placed in high temperature (being called hot junction), and the other end of p-type semiconductor and n-type semiconductor is placed in low temperature (being called cold junction), then the other end of p-type semiconductor and n-type semiconductor will form electrical potential difference.This electrical potential difference is relevant with the temperature difference of hot junction and cold junction.Alternatively, heat transfer generator also can not adopt semiconductor PN junction, and adopts bimetallic junction.
Refer to Fig. 3, the thermo-electric generation cooling device of the application's ignition coil posts heat transfer generator on the surface of ignition coil, between two pins of heat transfer generator, be connected with cooling element.Described heat transfer generator is preferably plane formula, and its one side is for contacting thermal source, and another side is for contacting low-temperature receiver.In this application, thermal source is the outer surface of ignition coil, and low-temperature receiver is ignition coil external environment.Described cooling element is such as fan, water cooling plant etc.
When ignition coil does not work, its internal-external temperature difference may be enough to drive cooling element after the conversion of heat transfer generator, also possibly cannot drive cooling element.For a kind of situation above, the application opens cooling element all the time.To a kind of situation later, after ignition coil is started working, its internal temperature rises, when higher than certain threshold value, the internal-external temperature difference of ignition coil can drive cooling element after the conversion of heat transfer generator, and now the application is equivalent to raise according to the internal temperature of ignition coil and automatically open cooling element.
Ignition coil is when normally working, and internal temperature is at about 170 DEG C, and ambient temperature is at about 90 DEG C.The temperature difference of 80 DEG C can make heat transfer generator produce the voltage of 4.8V, enough drives cooling element work.
After cooling element work, the flowing of ignition coil surrounding air can be accelerated, be conducive to ignition coil heat radiation.Along with the internal temperature of ignition coil reduces, when lower than certain threshold value, the internal-external temperature difference of ignition coil has been not enough to drive cooling element after the conversion of heat transfer generator, and now the application is equivalent to reduce according to the internal temperature of ignition coil and automatically close cooling element.
These are only the preferred embodiment of the application, and be not used in restriction the application.For a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection range that all should be included in the application.
