Description
Technical Field

Background
In the existing closed high-power electrical cabinet, an air-water heat exchanger is mostly adopted to take heat in the electrical cabinet out to the atmospheric environment for dissipation. The centrifugal fan of inseparable laminating is installed to geomantic omen heat exchanger top, forms circulation circuit through centrifugal fan's drive power in the regulator cubicle: the cold air in the electrical cabinet is firstly converted into hot air through the cooled device, and the hot air is then converted into cold air through the air-water heat exchanger.
The advantage of this kind of heat dissipation way is that the device to be cooled is generally in the air intake of the centrifugal fan, the air flow is comparatively homogeneous; the existing defects are that: only a centrifugal fan can be installed on the air-water heat exchanger, and although the air quantity of the centrifugal fan is large, a large installation space is required; good airtightness is kept between the air-water heat exchanger and the cooled device, otherwise the heat dissipation effect is greatly reduced; if other devices with large heat generation quantity exist in the path of the cold air blown by the centrifugal fan reaching the cooled device, the cold air is heated into hot air in advance, and the cooled device can not meet the derating requirement.
Therefore, a radiator mode which saves the installation space, is flexible and convenient to install and can enable cold air coming out of the heat exchanger to preferentially cool the cooled device is required urgently for searching for the closed high-power electrical cabinet.
