Abstract
The utility model relates to a power converter box, the structure space of which is divided into a device installation space and a radiator cooling space. The device installation space is formed by combining and welding a U-shaped component and an L-shaped component; the U-shaped component serves as the shell of the box; the L-shaped component is welded inside the shell; the U-shaped component is covered by a cover plate so as to form the device installation space inside the box; the cover plate is closed after devices are installed inside the device installation space, thus forming a closed space; and except the device installation space formed by the L-shaped component and the U-shaped component of the box, the radiator cooling space is the other part inside the box after the box consisting of the U-shaped component and the L-shaped component are welded.
Description
Technical field
The utility model relates to a kind of power electronic device modular construction, refers in particular to a kind of box inner structure of power converter device.Can be used for various power converter devices.
Background technology
The current transformer product generally all is made up of associated components such as power electronic device, control assembly, thermal component and casings, how to guarantee that for the little current transformer product of some batches the sealing of product, simplified structure design are the problems that each designer will face.
All include high tension apparatus such as power electronic device, support electric capacity in the now general current transformer product, also comprise control system closely, in order to guarantee reliability of products, these devices need carry out necessary protection, need accomplish water proof and dust proof, just these devices need encapsulation process.The main flow structure of existing current transformer product, main design philosophy is to carry out structural design around radiator, with power electronic device, support parts that needs such as electric capacity, control system protect be installed in radiator above, with a case lid these parts are all covered on the inside then, played the purpose of water proof and dust proof.This structural design scheme is simple, compact conformation, but this structure is the load-bearing main body of system with the radiator, (radiator is except installing the power electronic device greatly to cause radiator area, also to the basis be installed as other device), more with material, increased whole weight, in addition the binding post of capacitor and power electronic device not on same plane, make the busbar design production difficulty that meets be attached thereto strengthen.Fan guard and case lid that fan is installed generally all adopt thin metal material to form, can not load-bearing, so in production, transportation, placement, installation process, all need special consideration.The current transformer product various losses that invariably accompany in the course of the work simultaneously, these loss meetings consume with the form of heat, so power electronic device always is mounted on the radiator, if adopt air-cooled mode just must guarantee well-ventilated around the radiator.Just radiator can not adopt the mode of sealing.How to take into account the requirement of this two aspect, total again can not be too complicated simultaneously.Problem that the utility model need solve that Here it is has reduced the casing volume effectively, and making simplifies the structure is necessary.
The utility model content
The utility model is intended to solve more existing little in batches existing deficiencies of current transformer product, proposes a kind ofly can guarantee structural strength, sealing maintainability, the total current transformer body structure of complexity too again simultaneously.
For realizing above-mentioned target, the utility model structural design thinking is as follows: whole current transformer body structure space is divided into two parts, a part is the device installing space, and this space is a seal cavity after production is finished, and can play good protective action to device; The another one space is the radiator cooling space, is a space that is easy to realize circulation of air, is convenient to the heat radiation of product.Also changed the capacitor mounting means simultaneously, allowed the binding post of the binding post of capacitor and power electronic device, simplified the design and the production difficulty that connect busbar between them on same plane.Wherein, said device installing space is to be formed by U type structural member and L type structural member Combination Welding, U type structural member is the shell of casing, be welded with a L type structural member in the enclosure, on U type structural member, be stamped cover plate, make to form a device installing space in the casing, described device covers the space that cover plate will constitute a sealing after the installing space inner face installs; After described radiator cooling space is the casing that constituted of U type structural member and the welding of L type structural member, in remove box house another part space outside L type structural member and the formed device installing space of casing U type structural member.Be provided with the shutter of ventilation usefulness in the casing side of radiator cooling space.Tank floor at the radiator cooling space is provided with the ventilation hole that fan is installed.
Characteristics of the present utility model mainly this current transformer body structure design and produce simply, be convenient to small lot batch manufacture.At first a block plate is bent into " U type structural member ", be bent into " L type structural member " with a block plate again, the good steel plate of these two bendings according to requirement weld together and just constituted thematic structure, this wrap direction and this assembling mode have also strengthened bulk strength, all can adopt thin steel plate, further reduce the cost of product, alleviated weight.
