Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic components technology, specifically a capacitor assembly with high-efficiency heat dissipation function. Background Technology
[0002] A capacitor is an ideal element that characterizes the charge storage properties of a circuit element. Its original model is a parallel-plate capacitor consisting of two metal plates separated by an insulating dielectric. When a voltage is applied to the two plates, equal amounts of positive and negative charges accumulate on the plates, generating an electric field between the two plates. The more charge accumulated, the stronger the electric field, and the greater the electric energy stored in the capacitor.
[0003] A capacitor structure disclosed in patent announcement number CN221927788U includes a main capacitor. The main capacitor has a positive terminal and a negative terminal at its end. A first terminal is fixedly connected to both the positive terminal and the negative terminal, and the first terminal is electrically connected to both the positive terminal and the negative terminal. A first circuit board is fixedly mounted between the first terminal and the positive terminal and the negative terminal. The first circuit board is electrically connected to the positive terminal, the negative terminal, and the first terminal. A supercapacitor is soldered onto the first circuit board. The effect is as follows: By integrating and soldering multiple supercapacitors onto the first circuit board, each supercapacitor is connected in series, and the series-connected supercapacitors form a capacitor bank. Since the first circuit board is electrically connected to the main capacitor through the first terminal, the capacitor bank and the main capacitor are connected in parallel, thereby increasing the capacitance. Furthermore, the capacitor is smaller in size and easier to install due to the above connection method.
[0004] However, it still has some shortcomings, such as a single heat conduction path and low heat dissipation efficiency, which affects the lifespan of the component. To address these issues, we propose a capacitor component with high-efficiency heat dissipation, which solves the problems of a single heat conduction path and low heat dissipation efficiency affecting the lifespan of the component.
