Abstract

The utility model discloses a double-water-channel water cooling plate for a power module and aims at providing the double-water-channel water cooling plate, which is compact in structure, small in size, convenient to manufacture and use and reliable in cooling, for the power module. The double-water-channel water cooling plate for the power module comprises an intermediate plate, and the intermediate plate is arranged in the middle of the double-water-channel water cooling plate; water channel grooves which are mutually staggered are formed in two sides of the intermediate plate; a left side plate and a right side plate are symmetrically arranged on two side faces of the intermediate plate respectively; left water channel grooves and right water channel grooves which correspond to the water channel grooves on the intermediate plate are formed on surfaces of the left and right side plates which are symmetric to the intermediate plate; the left water channel grooves and the right water channel grooves form a left water channel and a right water channel respectively; and inlets and outlets of the left and right water channels are connected with inlet water pipe connectors and outlet water pipe connectors respectively. According to the utility model, insulated gate bipolar translator (IGBT) devices can be arranged on the left and right side plates on two sides of the water cooling plate, so that the double-water-channel water cooling plate for the power module is compact in structure, low in material consumption and low in manufacturing cost and high in safety, and wiring of IGBT devices can be conveniently and reliably realized.

Description

Power model is with the cooled plate of two water channels

Technical field

The utility model relates to cooling device, relates in particular to the cooled plate of a kind of inverted power module with two water channels.

Background technology

The High power Traction convertor equipment is widely used in 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 made up 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 great amount of heat 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, and the centre of cooled plate is shaped on the circulation water channel; Be connected with the water inlet pipe and water outlet pipe joint above; Connect cooling water pipe in the water pipe head, utilize cooling water the heat on the IGBT device to be conducted to cooled plate and take away, reach cooling purpose through cooled plate.Common cooled plate is to be processed by aluminum material, only is shaped on an individual layer circulation water channel back and forth in the cooled plate, and the effect of cooling is relatively poor; The monoblock cooled plate only can be equipped with the IGBT device on a face, work simultaneously and common inverted power module needs a plurality of IGBT devices, therefore; It is very big 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, also occur safety issue easily.

The content of utility model

The purpose of the utility model provides a kind of compact conformation, little, the manufacturing and easy to use of volume, cools off the cooled plate of reliable power model with two water channels.

In order to reach above-mentioned requirements; The utility model is realized through following scheme: it is characterized in that it includes the middle clamp plate in the centre; Be shaped on the water channel groove that staggers each other respectively in the two sides of middle clamp plate; Involutory respectively left plate and the right plate of being equipped with in the two sides of middle clamp plate; Being shaped on and corresponding left water channel groove of middle clamp plate water-supply line groove and right water channel groove with involutory left plate and the right plate surface of middle clamp plate, form left water channel and right water channel respectively, be connected with water inlet pipe respectively at the import and export of left water channel and right water channel and connect with outlet pipe and connect.

Use the cooled plate of two water channels according to the power model of such scheme manufacturing; Can on the left plate of the cooled plate left and right sides and right plate, the IGBT device be installed all, it has compact conformation, few, the low cost of manufacture of consumptive material; Easy-to-connect between each IGBT device, reliable, the advantage that fail safe is good.
