Embodiment Construction

[0059] The present invention will be described in further detail below in conjunction with specific examples, but the present invention is not limited to the following examples. The implementation conditions adopted in the examples can be further adjusted according to the different requirements of specific use, and the implementation conditions not indicated are the conditions in routine experiments.

[0060] 1. Synthesis of saturated polyester resin:

[0061] Add each raw material component into the stainless steel reaction kettle with agitator, cooling pipe and thermometer according to the formula amount in Table 1, start stirring, then add the catalyst antimony trioxide relative to the acid component 0.04mol%, and pass nitrogen In the case of , the temperature of the reaction kettle was raised to 160°C to 240°C, and the esterification reaction was carried out for 4 hours. Then release the pressure in the reactor. After 1 hour, the pressure in the reactor drops to 650Pa. Th...

Abstract

The invention relates to a radiator fin for a power module and a power module. The radiator fin comprises a copper layer, wherein an anti-oxidation coating covers one side of the copper layer, the anti-oxidation coating is composed of one or more than two inorganic oxides of silicon oxide, aluminum oxide, zirconium oxide, and titanium oxide as main component, the other side of the copper layer is combined with a resin layer which has insulation and heat dissipation function, and adhesive force after being heated. The radiator fin has excellent heat conduction performance and insulation property and facilitates the attaching and mounting of conducting layers and the resin layers. The power module made of the radiator fin has stable variable frequency working efficiency and service life.

Description

technical field [0001] The invention specifically relates to a heat sink for a power module and a power module made of it. Background technique [0002] The intelligent power module IPM (Intelligent Power Module), which was born in recent years, is a highly integrated power drive device, which can be used as a frequency conversion speed controller, and is used in textile machines, injection molding machines, frequency conversion air conditioners, washing machines, refrigerators, electric vehicles, radar servo systems, etc. middle. The use of IPM greatly improves the work efficiency of electronic and electrical products, and also reduces energy consumption. IPM integrates logic, control, detection and protection circuits, which is easy to use, not only reduces the size of the system and development time, but also greatly enhances the possibility of the system, adapting to the development direction of today's power devices - modularization, Composite and power integrated cir...
