Charging device power module

Abstract

The invention relates to a charging device power module. The charging device power module comprises a heat dissipation assembly and a power assembly, wherein the heat dissipation assembly is arranged below the power assembly, and supports the power assembly; a front side, a back side, a left side and a right side of the power assembly are provided with a front panel, a mounting plate, a left side plate and a right side plate respectively; the left side, the right side and the back side of the power assembly are connected with the left side plate, the right side plate and the mounting plate respectively; an upper cover plate is arranged above the power assembly; the upper cover plate is connected with the upper ends of the mounting plate, the left side plate and the right side plate respectively; a front side and a back side of the heat dissipation assembly are connected with the front panel and the mounting plate respectively; and upper ends of a left side and a right side of the heat dissipation assembly are connected with lower ends of the left side plate and the right side plate respectively. The charging device power module has the advantages of small size, high capacity, high heat dissipation speed, low noise and high replaceability. Through adoption of a standard and integral module design, the charging device power module can be mounted and repaired conveniently and rapidly, and can be produced and assembled in batches; the production efficiency is increased effectively; and the reliable running and stability of a tramcar charging device are ensured.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a power module of a charging device. Background technique [0002] Due to the innovative design of energy storage, the new modern tram has neither exhaust pollution nor overhead power grid operation. The biggest feature of this tram is that it uses a supercapacitor as the traction power supply, and there is no need to erect aerial cables "spider webs" ", can be laid directly on existing roads, mixed with other public transportation, without wasting land resources. At the same time, ground charging devices can be installed at each station. When the train enters the station, it can use the time for passengers to get on and off the train to quickly complete the charging. It can also absorb the energy generated during braking and convert it into electrical energy for storage and reuse. The recovery efficiency is over 85%. . The new modern tram has the characteristics of safety and...

Problems solved by technology

As the core component of the charging device, the power module of the tram charging device has strict requirements on heat dissipation due to its high temperature during operation. To ensure the normal operation of the tram charging device, power module products of conventional charging devices often use power modules The form of separate design from the heat dissipation system requires the design of a separate air duct, which occupies a large space in the device, has poor heat dissipation effect and high noise, cumbersome maintenance and disassembly of modules, and poor replaceability, which cannot meet customer requirements
