High-frequency resonant heating capacitor

The utility model discloses a high-frequency resonant heating capacitor comprising a housing, an electrode and a capacitor cores consists of a plurality of capacitor unit cores connected with each other. Around the capacitor cores is arranged insulating material in the housing and in the dry-structure capacitor is buried a cooler, both drawing ends of which are connected with an outside cooling pipe and the heat from the working capacitor can be radiated via the cooler to prolong the life-span of the capacitor. Meanwhile, the capacitor is provided with a compact structure and a simpler technical proposal. Furthermore, two unit cores connected in series with the other two and then connected in parallel with the two in the capacitors and the four capacitors connected in series with each other in each unit capacitor can insure the capacitor difficult to puncture in a relatively high temperature and overcome the faults of a plurality of welding joints in series at the outside, complex assembling technical proposal and high demand for the reeling apparatus.
