Description
Technical field
The utility model relates to electronic components technical field, particularly relates to a kind of frequency conversion electrical control modular assembly structure.
Background technology
The common radiating mode of power device is fin and two kinds, fan, and fin mode generally selected by frequency conversion electrical control plate.The thermal losses of device needs radiator to dissipate, but abnormal mounting can cause mechanical damage can damage shell moisture resistance or semiconductor chip is broken, cause too high junction temperature, cause shorten device lifetime; Device operation current is transshipped, larger electric current is passed through in short time in local space, can change into heat, heat not easily dissipates, and causes local temperature to raise fast, too high temperature can burn conduction copper sheet, wire and device itself, namely thermal failure is also modal a kind of failure mode, as can be seen here, if want the reliability of product to do height, on the one hand the high-temperature stability of equipment and parts is improved, larger thermal stress (because ambient temperature or overload etc. cause) can be born; Be strengthen heat radiation on the other hand, the heat that ambient temperature and overload are caused all dissipates, and product reliability is the same also can be improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, radiating efficiency is high, avoid power part to suffer the frequency conversion electrical control modular assembly structure of mechanical failure.
In order to realize above object, the technical solution adopted in the utility model is:
A kind of frequency conversion electrical control modular assembly structure, comprise frequency conversion electrical control plate and fin, backing plate is provided with between described frequency conversion electrical control plate and fin, the profile of described backing plate coordinates with frequency conversion electrical control plate, the edge in its front forms the button pawl for fastening frequency conversion electrical control plate, the edge formation of its bottom surface has the frame protruded to form spatial accommodation to make the bottom of backing plate downwards, the mounting groove for installation power part is also formed with in the bottom surface of backing plate, leave the through hole passed through for power part pin to contact with the pad of frequency conversion electrical control back to make the pin of power part at the edge of mounting groove simultaneously, after installation, the power part bottom backing plate and fin surface close contact.
After adopting said structure, the power part on frequency conversion electrical control plate adjusts to the bottom surface of backing plate from electric-controlled plate front, and more abundant with the contact of fin, its radiating effect is better.The spatial accommodation formed bottom backing plate not only has the effect holding power part, and the effect simultaneously also serving protection power part avoids power part suffer mechanical failure and have influence on the normal use of power part.
Further, the front of described backing plate is formed with positioning pin column, on frequency conversion electrical control plate, is reserved with the location hole coordinated with positioning pin column simultaneously.Cooperatively interacted by the location hole on the positioning pin column on backing plate and frequency conversion electrical control plate, quick position between frequency conversion electrical control plate and backing plate can be realized.
Preferably, contact-making surface roughness Ra≤6.3 μm between described backing plate and power part.Contact-making surface has good three thermal effects after adopting above-mentioned roughness.
Further, described backing plate front is formed with screwed hole, is reserved with the through hole corresponding to screwed hole position on electric-controlled plate simultaneously.By bolt hole corresponding to screwed hole position on the screwed hole in backing plate front and electric-controlled plate, the bolt that can realize between backing plate with electric-controlled plate is connected, and reinforces connection between the two further, makes structure more firm.
