Power cabinet with partitioning heat dissipation function

Abstract

The invention discloses a power cabinet with a partitioning heat dissipation function. The power cabinet comprises a cabinet body, and a power module, an electric reactor and a filtering capacitor arranged in the cabinet body, and also comprises an air channel partition plate arranged in the cabinet body; the cabinet body is divided into a first heat dissipation region and a second heat dissipation region by the air channel partition plate and a front door plate of the cabinet body; and the air channel partition plate and a back door plate of the cabinet body form a third heat dissipation region which is on the upper parts of the first heat dissipation region and the second heat dissipation region. By virtue of the power cabinet with the partitioning heat dissipation function, partitioningheat dissipation can be realized, so that thermal influence of a high-power heating device electric reactor on a heat sensitive device can be avoided, and efficient heat dissipation can be achieved.

Description

technical field [0001] The invention relates to the technical field of ventilation and heat dissipation, in particular to a power cabinet with partitioned heat dissipation. Background technique [0002] With the rapid development of wind energy, wind power converters are required to be smaller in size and higher in power density, and the layout of heating devices and heat-sensitive devices inside the cabinet is complicated. Design a more efficient and reasonable heat dissipation system, which can realize zonal heat dissipation, make reasonable use of limited cooling, and realize temperature zonal control. Therefore, a solution design for power cabinet partition heat dissipation has become a key issue for wind power converter products. [0003] In the current design of high-power cabinets, especially in the air-cooled heat dissipation method, the installation distance between the high-power heating device and the heat-sensitive device is very close, or the phenomenon that th...

Problems solved by technology

[0003] In the current design of high-power cabinets, especially in the air-cooled heat dissipation method, the installation distance between the high-power heating device and the heat-sensitive device is very close, or the phenomenon that the cold air passes through the high-power heat-generating device first and then passes through the heat-sensitive device is very likely to occur. This will lead to the problem that thermally sensitive devices are affected by thermal radiation or thermal convection of high-power heating devices, and the temperature is too high to cause failure.
