A high-power outdoor cabinet cooling air duct structure

Abstract

A high power outdoor cabinet cooling air duct structure comprises air inlet structure components at the two sides of the top of a cabinet and cabinet air outlet structures at the two sides of the bottom of the cabinet. The cabinet is separated four independent cavity chambers by air duct dummy plates according to different heat resistance level of the components in the cabinet, and the four independent cavity chambers are a first cavity chamber, a second cavity chamber, a third cavity chamber and a fourth cavity chamber. The high power outdoor cabinet cooling air duct structure further comprises an axial flow fan, a backward centrifugal fan and an electric reactor, wherein the axial flow fan is arranged in the first cavity chamber and is located at the bottom of the air duct dummy plate between the first cavity chamber and the second cavity chamber; the backward centrifugal fan is arranged in the third cavity chamber and is linked with a GBT module radiator structure component, the electric reactor is arranged below the backward centrifugal fan; the air inlet structure component at the one side of the top of the cabinet is communicated with the first cavity chamber, and the air inlet structure component at the other side is communicated with the third cavity chamber. The air duct has the advantages of being simple and compact in structure, high in protective capability, high in cooling efficiency and low in cost.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of high-power outdoor cabinets, in particular to a heat dissipation air duct structure of high-power outdoor cabinets. Background technique [0002] Traditional high-power outdoor cabinets use forced air cooling for heat dissipation, and the cabinet air duct adopts the form of bottom in and top out. An additional "herringbone" protective structure is required above the wind outlet at the top. [0003] Disadvantages of this type of air duct: the air intake at the bottom of the cabinet is low, and under the action of negative pressure, light and small obstacles are easily gathered at the air intake, resulting in the obstruction of the air intake, which in turn affects the heat dissipation of the whole machine; With an additional protective structure, fans and air outlets must be installed in each chamber where electronic components are placed. The design of the air duct is relatively compl...
