Embodiment Construction

[0029] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0030] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, a heat dissipation structure of electric car capacitor system, the heat dissipation structure is preferably applied to the super capacitor of electric car, which includes: capacitor cabinet 100, skeleton assembly 200, capacitor unit 300 and air intake assembly, it is worth explaining here that , the existing heat dissipation structure usually uses air cooling and water cooling to cool down the overall temperature of the capacitor cabinet 100, without considering the temperature difference after cooling between each super capacitor, if after cooling, the temperature of each super capacitor module 310 If the difference is too la...

Abstract

The invention provides a cooling structure of a trolley bus capacitor system. The cooling structure comprises a capacitor box, a framework assembly, a capacitor unit and an air inlet assembly, and theframework assembly is arranged in the capacitor box and is provided with a tray; the capacitor unit is arranged on the tray and comprises several super capacitor modules, all the super capacitor modules are arranged in an array, and parallel ventilation gaps and series ventilation gaps are formed among the super capacitor modules; the air inlet assembly corresponds to the capacitor unit and is used for forming parallel and series air in the framework assembly. The cooling structure has the advantages that the capacitor unit can be cooled, the cooling consistency of all capacitors is good, andthus the service life of a super capacitor applied to a trolley bus is prolonged.

Description

technical field [0001] The invention belongs to the technical field of trams, and relates to a heat dissipation structure of a capacitor system of a tram. Background technique [0002] Supercapacitors are widely used in rail vehicles and other public transportation vehicles. Since the super capacitor is sensitive to temperature, too high or too low temperature will obviously affect the performance of the super capacitor. Therefore, according to the ambient temperature and the usage of the vehicle, the necessary heat dissipation or heating system must be configured. [0003] For example, a Chinese patent with application number 201621404725.8 discloses a supercapacitor cooling system, which relates to the field of supercapacitors. The supercapacitor heat dissipation system includes a base, the top of the base is fixedly connected to the inside of the capacitor through a support block, the surface of the capacitor is fixedly installed with an upper tube ring and a lower tube ...
