Description
Technical field
The utility model is related to electrical equipment, specifically a kind of glass ceramics high temperature high voltage resistant silicon stack.
Background technology
Current high voltage silicon rectifier stack is often that insulating materials is subject to embedding shaping with epoxy resin, due to the heat conduction system of epoxy resin
Number very small (0.2~2.2), the heat that high voltage silicon rectifier stack work is distributed can not rapidly conduct, and the heat of inside aggregation is easy to
High voltage silicon rectifier stack unstable properties are caused, rectification efficiency is not high, leakage loss is increased, or even voltage breakdown or inside are burnt, according to
This process structure and packaged type of conventional high voltage silicon rectifier stack, corresponding support circuit, testing equipment and supporting application,
Oil cooling is all used, air-cooled, the scheme such as attached heat abstractor increases energy consumption and manpower and materials.
Utility model content
The purpose of this utility model is to provide a kind of glass ceramics high temperature high voltage resistant silicon stack, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
Multiple glass-encapsulateds are provided with a kind of glass ceramics high temperature high voltage resistant silicon stack, including ceramic package 2, ceramic package 2
Diode 5, be serially connected between diode 5 to be formed between high voltage silicon rectifier stack die assemblies, and the copper lead of diode 5 by weldering
Joint 4 is welded to each other, and the high voltage silicon rectifier stack die assemblies connection extends to the electrode outlet line 1 in the outside of ceramic package 2；The pottery
Cryogenic glass powder packed layer 3 filled with paste in ceramic shell 2, it is overall using ceramics and cryogenic glass powder, therefore overall tool
There is preferable heat dispersion, and ceramics and cryogenic glass powder have preferable heat resistance, and ceramics and cryogenic glass powder also have
There are good insulating properties.
As further program of the utility model：The plumb joint 4 connects diode 5 in the form of AC welding
Copper lead.
As the utility model further scheme：The cryogenic glass powder packed layer 3 is molded in the form of sintering.
Compared with prior art, the beneficial effects of the utility model are：The utility model is filled with cream in ceramic package
The cryogenic glass powder packed layer of shape, it is overall using ceramics and cryogenic glass powder, therefore entirety has preferable heat dispersion, and
And ceramics and cryogenic glass powder have preferable heat resistance, ceramics and cryogenic glass powder also have good insulating properties.
Brief description of the drawings
Fig. 1 is a kind of structural representation of glass ceramics high temperature high voltage resistant silicon stack of the utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out

Fig. 1 is referred to, in the utility model embodiment, a kind of glass ceramics high temperature high voltage resistant silicon stack, including ceramic package
2, the diode 5 of multiple glass-encapsulateds is provided with ceramic package 2, it is serially connected to form high voltage silicon rectifier stack tube core group between diode 5
It is welded to each other by plumb joint 4 between part, and the copper lead of diode 5, the high voltage silicon rectifier stack die assemblies connection extends to pottery
The electrode outlet line 1 in the outside of ceramic shell 2；The cryogenic glass powder packed layer 3 filled with paste, integrally adopts in the ceramic package 2
Have preferably with preferable heat dispersion, and ceramics and cryogenic glass powder with ceramics and cryogenic glass powder, therefore entirety
Heat resistance, ceramics and cryogenic glass powder also have good insulating properties.
The plumb joint 4 connects the copper lead of diode 5 in the form of AC welding.
The cryogenic glass powder packed layer 3 is molded in the form of sintering.
Operation principle of the present utility model is：Cryogenic glass powder packed layer 3 filled with paste in ceramic package 2, it is overall
Using ceramics and cryogenic glass powder, thus it is overall there is preferable heat dispersion, and ceramics and cryogenic glass powder have compared with
Good heat resistance, ceramics and cryogenic glass powder also have good insulating properties.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each implementation method is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Specification an as entirety, the technical scheme in each embodiment can also be formed into those skilled in the art through appropriately combined
May be appreciated other embodiment.
