Description

Technical Field

[0001] This utility model relates to the technical field of ignition coil devices, specifically to intelligent temperature-controlled ignition coils. Background Technology

[0002] Throughout the development of automotive ignition systems, the ignition coil has always been a crucial component. Traditional ignition coils, when in operation, convert the low voltage output from the vehicle battery into a high voltage that enables the spark plugs to generate a spark. This process involves significant energy conversion and consumption, leading to a rapid increase in the internal temperature of the ignition coil.

[0003] Traditional ignition coils are designed primarily for electromagnetic conversion, resulting in significant shortcomings in heat dissipation. Their internal windings consist of numerous tightly wound enameled wires, making it difficult for heat to be quickly conducted to the outside. Furthermore, the coil casing is often made of materials with good insulation properties but poor thermal conductivity, further hindering heat dissipation. Prolonged operation in high-temperature environments gradually degrades the insulation material, leading to short circuits, open circuits, and other malfunctions, severely impacting the normal operation of the ignition system and engine performance.

[0004] Meanwhile, traditional ignition coils generate strong electromagnetic interference during operation. Ignition coils based on the principle of electromagnetic induction generate a rapidly changing magnetic field when the primary coil is energized and de-energized. This magnetic field not only induces a high voltage in the secondary coil but also radiates electromagnetic waves into the surrounding space. Utility Model Content
