Abstract
The invention discloses an energy storage pulse capacitor. The energy storage pulse capacitor comprises a housing. An epoxy resin encapsulating layer is arranged inside the housing. Two ends of the epoxy resin encapsulating layer are provided with metal electrodes. A first polyester film and a second polyester film are arranged in a parallel mode in the epoxy resin encapsulating layer. One side surface of the first polyester film is completely plated with an aluminium zinc alloy layer. One side surface of the second polyester film is plated with three aluminium zinc alloy layers which are parallel to each other. A same interval is arranged between each of the two adjacent aluminium zinc alloy layers. The external surface of the housing is provided with a ventilation slot. According to the invention, the polyester films with a high pressure-resistant value are provided, so that the energy storage density of the energy storage pulse capacitor is raised. The ventilation slot arranged in the housing can accelerate the air circulation around the capacitor and improve heat radiation effects.

Energy-storage pulsed capacitor is widely used in playing the effect of energy storage in the equipment such as electromagnetism accelerator, pulse laser power supply.Along with the miniaturization of plant equipment, also more and more higher to the requirement of the energy storage density of energy-storage pulsed capacitor and radiating efficiency, common energy-storage pulsed capacitor can not adapt to these requirements.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of energy-storage pulsed capacitor, can solve the deficiencies in the prior art, by the high polyester film of withstand voltage is set, improved the energy storage density of energy-storage pulsed capacitor, the ventilation slot of shell setting can be accelerated the circulation of air around the capacitor, improves radiating effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of energy-storage pulsed capacitor, in comprise shell, enclosure is provided with the epoxy encapsulation layer, be provided with metal electrode at epoxy encapsulation layer two ends, in described epoxy encapsulation layer, be arranged with first polyester film and second polyester film in parallel, first polyester film, one side surface all is coated with the alumin(i)um zinc alloy layer, second polyester film, one side surface is coated with three alumin(i)um zinc alloy layers that are parallel to each other, and the gap between adjacent two alumin(i)um zinc alloy layers is identical; The outer surface of described shell is provided with ventilation slot.
As preferably, described first polyester film (4) and described second polyester film (5) all adopt piecemeal evaporation and non-homogeneous evaporation coating technique to make, and are made of the countless modules of cutting apart, and all link to each other by very thin evaporation metal silk between disparate modules.
As preferably, the material of described metal electrode is silver.
As preferably, on described shell, also be provided with mounting ear, mounting ear is arranged on the offside of described ventilation slot, and mounting ear makes described shell and mounting plane have the gap.
The beneficial effect that adopts technique scheme to bring is: the present invention adopts the polyester film that has al-zn alloy coating, can improve the withstand voltage of electric capacity.The different designs of the coating of two polyester films can increase the effective area of polyester film, improves the field intensity of electric capacity inside, is convenient to reduce the volume of electric capacity.Adopt silver as electrode, can reduce contact resistance, reduce caloric value.Use aluminium shell, can improve radiating efficiency.The ventilation slot of shell setting can be accelerated the circulation of air around the shell.When using mounting ear that electric capacity is installed, because the supporting role of mounting ear makes shell and mounting plane have certain clearance, be conducive to the circulation of air heat radiation.
