In the prior art, some IGBT mould groups with radiator, each IGBT monomer are usually directly pressed by pressing plate
On the surface of radiator, so that realizes IGBT and radiator thermally contacts connection, the heat of IGBT at work is taken away by radiator
Amount, prevents IGBT high temperature.Each IGBT monomer of this IGBT mould group is to contact firmly with radiator, and after long-time service, IGBT is mono-
Body and radiator are easy to loosen, and cause the heat of IGBT monomer that cannot quickly be transferred to radiator.
In addition, will not protect to the pin of IGBT in existing IGBT mould group, the pin of IGBT is very in use
It is easy to draw vibration and be subjected to displacement.
Summary of the invention
The purpose of the application is: in view of the deficiencies of the prior art, the application proposes a kind of IGBT mould group with radiator structure,
To guarantee IGBT mould group radiating efficiency still with higher after being used for a long time.
The technical solution of the application is:
A kind of IGBT mould group with radiator structure, including a radiator and several IGBT further include and the heat dissipation
The plastic protection casing that device is detachably fixed, that side of the plastic protection casing towards the radiator are formed with several IGBT peace
Tankage, each IGBT are arranged in correspondingly respectively in each IGBT mounting groove, and each IGBT peace
It is arranged in tankage and is clipped between the plastic protection casing and the IGBT and the IGBT is applied towards the radiator
The spring of direction elastic force, each IGBT the spring elastic force effect under with the radiator abutting contact.
The application further includes following preferred embodiment based on the above technical solution:
The pin location hole protruded into the IGBT mounting groove is also provided on the plastic protection casing, the IGBT's
Pin is inserted in the pin location hole.
The spring is multi-layer corrugated spring.
The slot bottom of the IGBT mounting groove is formed with spring positioning slot, and one end of the multi-layer corrugated spring inserts in the spring
In locating slot.
The radiator is cold forging radiator.
The side of the radiator is provided with several thermal columns.
The plastic protection casing is connect with the radiator by screw locking.
The plastic protection casing is snapped connection with the radiator.
The application has the advantage that compared to traditional technology
1, the elastic force that the application applies IGBT2 by spring contacts IGBT with radiator resilient abutment, is used for a long time
It still is able to guarantee that IGBT is contacted with the good of radiator, makes IGBT mould group radiating efficiency with higher always.
2, the pin location hole being arranged on plastic protection casing, guarantee mould group is in the case where external vibration, the pin of IGBT
Non-displacement.
3, the slot bottom of IGBT mounting groove is formed with spring positioning slot, and one end of multi-layer corrugated spring inserts in spring positioning slot,
Guarantee that the position of multi-layer corrugated spring is accurate.
4, radiator is using cold forging radiator made of cold-forging technique, and side is provided with numerous thermal columns, is had excellent
Good heat dissipation performance.
Detailed description of the invention
