AI Technical Summary
High-frequency transformers for air conditioners face challenges in heat generation and heat dissipation during high-frequency operation. Furthermore, the impregnating liquid is prone to loosening under high-temperature conditions, leading to structural instability and impacting the safety of air conditioner operation.
A high-frequency transformer structure for air conditioning with easy heat dissipation was designed. Heat dissipation grooves were set on both sides of the top base to increase the heat dissipation area. Irreversible adhesive encapsulation layer was used to fill the gaps between the magnetic core, frame and windings. The positioning groove structure was optimized to ensure the alignment and fixation of the magnetic core.
It effectively alleviates heat accumulation during high-frequency operation, enhances structural stability, reduces the risk of inter-turn short circuits, and improves the heat dissipation efficiency and service life of air conditioning high-frequency transformers.
