New restriction.
See figures.1.and.2, this utility model embodiment provides a kind of IGBT module shell, including body 1, on body 1
The anti-cosmic ray material that anti-cosmic ray ability is better than body 1 is provided with, example, the anti-cosmic ray material can be
Lead.
The IGBT module shell that this utility model embodiment is provided, is better than because body 1 is provided with anti-cosmic ray ability
The anti-cosmic ray material of body 1, therefore the anti-cosmic ray ability of body 1 can be lifted, so as to body 1 need not be significantly increased
Thickness, and then the problem that the volume and weight of IGBT module is multiplied is alleviated, also facilitate the use of IGBT module.
Specifically, body 1 includes roof 11, diapire 12 and the annular sidewall 13 between roof 11 and diapire 12,
The anti-cosmic ray material is equipped with roof 11, diapire 12 and side wall 13, roof 11, diapire 12 and side thus can be made
The anti-cosmic ray ability of wall 13 gets a promotion, so that the thickness of roof 11, diapire 12 and side wall 13 is without the need for significantly
Increase, and then further alleviate the problem that the volume and weight of IGBT module is multiplied.
In the first embodiment of the present utility model, with reference to Fig. 1, the anti-cosmic ray material be scattered in roof 11,
In diapire 12 and side wall 13, thus extra fixed structure can be set, so as to save cost；
Further, since the igbt chip 2 in IGBT module shell needs to be radiated by roof 11 and diapire 12, therefore
Roof 11 and diapire 12 are generally made from the stronger metallic copper of the capacity of heat transmission, and the capacity of heat transmission of anti-cosmic ray material is compared
Metallic copper is weaker, therefore, anti-cosmic ray material is scattered in roof 11 and diapire 12 in the present embodiment can reduce anti-universe
The density of ray material, so as to reduce the impact that anti-cosmic ray material is caused to roof 11 and the capacity of heat transmission of diapire 12, enters
And reduce the impact caused to the proper heat reduction of igbt chip 2.
In second embodiment of the present utility model, with reference to Fig. 2, it is equipped with roof 11, diapire 12 and side wall 13
The layer structure 3 by made by the anti-cosmic ray material, thus can increase the density of anti-cosmic ray material, so as to improve
The anti-cosmic ray ability of roof 11, diapire 12 and side wall 13.It should be noted that layer structure 3 can be embedded in roof 11, bottom
In wall 12 and side wall 13, the surface of roof 11, diapire 12 and side wall 13 is also securable to, this utility model is not limited this
It is fixed.
In the third embodiment of the present utility model, the anti-cosmic ray material is scattered in roof 11 and diapire 12
Interior, side wall 13 is provided with the layer structure 3 by made by the anti-cosmic ray material, and on the one hand this compound mode can reduce top
The density of the anti-cosmic ray material in wall 11 and diapire 12, so as to reduce anti-cosmic ray material to roof 11 and diapire 12
The impact that the capacity of heat transmission is caused, and then reduce the impact caused to the proper heat reduction of igbt chip 2；On the other hand side wall can be increased
The density of the anti-cosmic ray material on 13, so as to improve the anti-cosmic ray ability of body 1.Certainly, in IGBT module pipe
In the course of processing of shell, also dependent on the complexity of technique, flexibly using other compound modes.
Roof 11 and diapire 12 in IGBT module shell needs conduction, side wall 13 to need to prevent roof 11 and diapire 12 from leading
Leading to, therefore be scattered in the described anti-cosmic ray material in side wall 13 to insulate, and is scattered in roof 11 and diapire 12
The anti-cosmic ray material was both electrically conductive, it is also possible to insulate, is preferably dispersed in the present embodiment in roof 11 and diapire 12
Described anti-cosmic ray material it is electrically conductive, to avoid causing shadow to the conductive capability and the capacity of heat transmission of roof 11 and diapire 12
Ring.
With reference to Fig. 2, the layer structure 3 on side wall 13 was both electrically conductive, it is also possible to insulate, when the layer structure 3 is led
When electric, need to avoid the layer structure 3 from contacting with roof 11 and/or diapire 12, to prevent roof 11 and diapire 12 from turning on, but this
Sample yet suffers from the risk for turning on, in order to evade the risk completely, the layer structure 3 being preferably placed in the present embodiment on side wall 13
Surface insulation.Specifically, directly the layer structure 3 can be made from the anti-cosmic ray material of insulation, or from conductive
Anti- cosmic ray material make the layer structure 3, then insulation processing is carried out to the surface of the layer structure 3.
Layer structure 3 on roof 11 and diapire 12 was both electrically conductive, it is also possible to insulate, the present embodiment is preferably placed at
Layer structure 3 on roof 11 and diapire 12 is electrically conductive, to avoid conductive capability and the capacity of heat transmission to roof 11 and diapire 12
Impact.
