Problems solved by technology
However, the existing IGBT heat dissipation solutions for frequency conversion control boards all use large-scale IGBTs to dissipate heat by enlarging the PCB area of the frequency conversion control board.
With the continuous development of the miniaturization trend of frequency conversion control boards, large-size PCB boards and large-capacity IGBTs have been unable to adapt to the current trend of thinner and lighter electronic products, and urgent improvement is needed
In addition, the larger the area of the printed circuit board of the frequency conversion control board, the higher the cost

The invention relates to a variable frequency control panel. Specifically, the invention provides a variable frequency control panel for a variable frequency refrigerator. The variable frequency control panel comprises a printed circuit board, a plurality of power devices heating during working and at least one jumper wire, wherein a plurality of via holes penetrating through the printed circuit board are formed in the printed circuit board; the power devices are mounted on the back surface of the printed circuit board; two ends of each jumper wire are respectively welded on the front surface of the printed circuit board and respectively cover the via holes, and each jumper wire crosses two transverse sides or two longitudinal sides of the corresponding power device; the surface area of each jumper wire is a preset multiple of the area of the lamination surface of the corresponding power device. According to the variable frequency control panel provided by the invention, due to the adoption of the jumper wire for heat dissipation, the heat dissipation area of the variable frequency control panel is significantly improved, the heat dissipation efficiency of the variable frequency control panel is improved, and the area of the panel surface of the variable frequency control panel is saved, so that the variable frequency control panel is conductive to reducing the size of the panel surface, reducing manufacturing cost and ensuring the service life of the variable frequency control panel.
Description
technical field [0001] The invention relates to the field of heat dissipation of circuit boards, in particular to a frequency conversion control board. Background technique [0002] The circuit board is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Almost all electronic products include circuit boards. As the integration of circuit boards becomes higher and higher, the components on the circuit boards are arranged more and more densely, and the heat dissipation area is insufficient, especially around high-heating components. Exceeded the standard. For example, for a frequency conversion control board with a circuit board, the power device IGBT of the frequency conversion control board emits a large amount of heat during use, and it is necessary to reduce the device temperature to ensure the quality and life of the frequency conversion control board. However, the existing heat dissipa...
