[0002] As an indispensable component of electronic devices, the stability and control of the operating temperature of multilayer capacitors has become a key technical concern. Excessive temperatures not only affect the performance of multilayer capacitors but can also shorten their service life. Therefore, cooling technology for multilayer capacitors is particularly important.

[0003] Patent publication number CN207602404U discloses a stacked capacitor, which specifically discloses that "the stacked capacitor includes a plurality of stacked monomers, and a positive lead terminal and a negative lead terminal electrically connected to the monomers, each monomer includes a positive terminal, a negative terminal, and a shielding rubber wire located between the positive terminal and the negative terminal; the negative terminals of the monomers are connected together and connected to the negative lead terminal; the positive terminals of the monomers are connected together and connected to the positive lead terminal, and the positive terminal of each monomer is the portion of the aluminum foil extending out of the shielding rubber wire, and the aluminum foil is sintered. The sintered foil is provided with a welding area for welding the positive terminal and the positive lead terminal of each cell together, and the positive lead terminal is electrically connected to the welding area. This technical solution realizes the "use of sintered foil instead of traditional corroded aluminum foil to prepare laminated solid-state capacitors, reserving a welding area on the aluminum foil so that the aluminum oxide dielectric film does not grow in this area, and then welding the positive lead terminal to the welding area. The final product. The laminated capacitor provided by this utility model has the technical effect of low ESR and large capacity, especially obvious advantages in high-voltage products."

[0004] This utility model only increases the capacity of the capacitor by using welding technology, but does not consider the capacitance of the capacitor in a high-temperature environment. The utility model improves on this basis. When the temperature regulator senses that the temperature is too high, it triggers a linkage reaction of the power-off device, sliding the paddle plate down to disconnect the power supply. The capacitor shell is provided with a ventilating hole, and a ventilation layer is left between the shell and the capacitor bank to accelerate the flow of cold air and the dissipation of hot air. Condensation heat sinks are installed on the outside of the capacitor bank. Multiple cooling structures work simultaneously to ensure the health of the capacitor capacitance and extend the service life while ensuring operational safety. Utility Model Content
