Description

Two-sided intensive power model

Technical field

The utility model relates to power equipment, relates in particular to the two-sided intensive power model in the current transformer.

Background technology

The High power Traction convertor equipment is widely used in the occasions such as high-speed railway transportation, urban track traffic.The high power contravariant power model is directly born the task that reliable inversion power supply is provided for traction electric machine as one of core component of High power Traction convertor equipment.This power model is comprised of high-power IGBT device, lamination power generatrix, water cooler, filter capacitor, opto-electric connector, DC power supply and structural support.Owing to can produce a large amount of heats during the work of IGBT device, therefore need the water cooler cooling, the common type of cooling is that the IGBT device is installed on the cooled plate, the centre of cooled plate is shaped with cyclic water channel, the above is connected with the water inlet pipe and water outlet pipe joint, connect cooling water pipe in the water pipe head, utilize cooling water by cooled plate the heat on the IGBT device to be conducted to cooled plate and take away, reach the purpose of cooling.Common cooled plate is to be made by aluminum material, only be shaped with an individual layer cyclic water channel back and forth in the cooled plate, the effect of cooling is relatively poor, and the monoblock cooled plate only can only be equipped with the IGBT device at a face, and common inverted power module need to have a plurality of IGBT devices to work simultaneously, therefore, it is very large that cooled plate can be done, and except the bulky defective of cooled plate, the mutual wiring between the IGBT device also can be disorderly, make troubles for installation and use, safety issue also easily occurs.

The content of utility model

The purpose of this utility model provides that a kind of compact conformation, volume are little, manufacturing and easy to use, cools off reliable two-sided intensive power model.

In order to reach above-mentioned requirements, the utility model is realized by following scheme: it includes cooled plate, in cooled plate the IGBT device is installed, it is characterized in that described cooled plate is double-deck cyclic water channel, two sides in cooled plate all are equipped with the IGBT device, the IGBT device of same side connects by power generatrix on the cooled plate, and same end is exported by lead-out terminal.

Described double-deck cyclic water channel includes the middle clamp plate in the centre, involutory left plate and the right plate of being equipped with respectively in the two sides of middle clamp plate, between middle clamp plate and left plate and right plate, be shaped with left water channel and the right water channel of independent loops, be connected with respectively water inlet pipe at the import and export of left water channel and right water channel and connect with outlet pipe and connect.

Two-sided intensive power model according to the such scheme manufacturing, because cooled plate has preferably cooling performance, left and right sides in cooled plate can be installed the IGBT device, it has compact conformation, consumptive material is few, low cost of manufacture, easy-to-connect between each IGBT device, reliable, the advantage that fail safe is good.
