Problems solved by technology
[0002] At present, the use of frequency conversion air conditioners is becoming more and more widespread, especially the popularity of high-power frequency conversion air conditioners is becoming more and more widespread, but the power components of frequency conversion air conditioners such as IGBT devices ), diodes, etc., due to the limitation of the process, are currently using non-insulated designs for reliable heat dissipation, which brings about a difficult problem, because the power components are all with high voltage when they are working, and at the same time they are Working in high current mode, the heat is very severe, so reliable heat dissipation must be carried out, and reliable insulation must also be taken into account

The invention discloses a circuit board assembly, an electric control box for air conditioners, and an air conditioner. The circuit board assembly includes a circuit board, power components, a metal cooling plate, and a heat conducting and insulating layer. The power components are arranged on the circuit board. The metal cooling plate is provided with accommodating slots for installing a refrigerant cooling pipeline. The heat conducting and insulating layer is arranged between the metal cooling plate and the power components to insulate the metal cooling plate from the power components and to connect the metal cooling plate and the power components through heat conduction. The refrigerant cooling pipeline is in heat conduction connection with the power components through the metal cooling plate and the heat conducting and insulating layer to cool the power components efficiently, and the heat conducting and insulating layer insulates the power components from the metal cooling plate. Therefore, the power components can both be cooled efficiently and insulated.
