2nd terminal 5；The inside of end cap 3 is provided with radiating seat 6, and at least one radiator fan 7 is provided with radiating seat 6, radiating seat 6
Surface offers several the 1st heat emission holes 8, and several the 2nd heat emission holes 9, also, the 1st radiating are also offered in the side of end cap 3
Hole 8 and the interlaced arrangement of the 2nd heat emission hole 9；1st heat emission hole 8 and the 2nd heat emission hole 9 use interlaced arrangement mode, and advantage is：Can either
Heat in radiating seat is dispersed into external environment condition by realization, also can prevent outside debris from entering in radiating seat, so as to disturb
The normal performance of radiating seat；, can also be in the appearance of end cap 3 if further improving the anti-dust performance of equipment in practical application
Bread wraps up in ventilation waterproof membrane.
Radiating seat 6 is also separately installed with the 1st radiating tube 10 and the 2nd radiating tube 11 being vertically arranged, the 1st radiating tube 10 and
2 radiating tubes 11 can use the thermal conductive silicon sebific duct for offering thermal vias.The 1st wire 12 that 1st terminal 4 is connected passes through the 1st
Radiating tube 10 and be connected on electric capacity core body 2；The 2nd wire 13 that 2nd terminal 5 is connected is connected to through the 2nd radiating tube 11
On electric capacity core body 2.By setting radiating tube, on the one hand, heat caused by wire effectively can be dispersed into external environment condition, it is real
Now efficient radiating effect；On the other hand, two radiating tubes also play a part of stationary positioned to wire, prevent wire or so from shaking
The situation moved and broken, improve the soundness of terminating wire.In practical application, the 1st radiating tube 10 and the 2nd radiating tube
11 be the thermal conductive silicon sebific duct for offering thermal vias.Radiator fan 7 is thermistor Minitype radiating fan.
In practical application, guide rail can be set between end cap and capacitor, spring is arranged with guide rail, end cap passes through lock
It is connected with capacitor；Therefore, when pressure is normal in capacitor, end cap is fixed on capacitor by lock, and capacitor is normal
