23 Jul And IGBT driving module is additionally provided with thermal insulation material
Abstract
The IGBT driving module is additionally provided with a thermal insulation material, the IGBT driving module is additionally provided with a thermal insulation material, the thermal insulation material is super tissue paper, and the super tissue paper is insulation thermal insulation tissue paper. The IGBT driving module also comprises a circle of adhesive, and the adhesive is a temperature-sensitive epoxy resin AB structural adhesive. According to the technical scheme of the utility model, the IGBT driving module is adopted. Improved addition of thermal insulation material, the failure problem caused by heat conduction to the driving circuit board when the IGBT module works can be eliminated; by applying the super tissue paper heat insulation material, the temperature of the drive circuitboard can be reduced by more than 20 DEG C, the normal work of the circuit board is ensured, the service life of the whole IGBT drive module is prolonged, the adaptability of the IGBT drive module toa high-temperature environment is effectively improved, and compared with a ventilation and heat dissipation fan additionally arranged on the whole frequency converter, the transformation cost is low, and the engineering quantity is small.
