Problems solved by technology

Equally, because the temperature of the air sucked by the second blower fan 1-2 is higher, its life-span will also be affected
In addition, and the second fan 1-2 is located on the top of the cabinet 1-6, it will also cause the problem of high noise in the heat dissipation system

[0045] refer to figure 2 , the first embodiment of the high-power cabinet heat dissipation system of the present invention includes: a cabinet 2-6, a main air duct 2-5 formed in the cabinet 2-6, and a first heating component arranged in the main air duct 2-5 2-2. The first fan 2-3 and the second heating component 2-4.

[0046] The cabinets 2-6 can adopt a traditional structure, such as a rectangular parallelepiped cabinet.

[0047] A first opening 2-7 and a second opening 2-1 are provided at both ends of the main air duct 2-5. The position of the first opening 2-7 is set at the bottom of the cabinet of the cabinet 2-6, close to the ground or other platforms where the cabinet is placed, and the position of the second opening 2-1 is set at the top of the cabinet of the cabinet 2-6, away from the ground where the cabinet is placed or other platforms.

[0048] The first fan 2-3 is an axial fan or a centrifugal fan. When the cross-sectional size of the main air duct 2-5 is relati...

Embodiment 2

[0053] refer to image 3 , the second embodiment of the high-power cabinet cooling system of the present invention differs from the first embodiment in that: the first opening 2-7 of the main air duct 2-5 is connected to the air outlet direction of the first fan 2-3 The mutual relationship is different, that is, in the second embodiment, the position of the first opening 2-7 of the main air duct 2-5 is located on the side of the bottom of the cabinet 2-6, and the direction of its air intake is the same as that of the first opening 2-7 of the main air duct 2-5. Two openings 2-1 are vented in a vertical direction. Other parts of the second embodiment are the same as those of the first embodiment, and will not be repeated here.

Embodiment 3

[0055] refer to Figure 4 , the third embodiment of the high-power cabinet cooling system of the present invention is different from the second embodiment in that: the air inlet of the main air duct 2-5, that is, the first opening 2-7 is arranged on the bottom and side of the cabinet , so that the air inlet of the main air duct 2-5 not only has the air inlet direction perpendicular to the air outlet direction of the second opening 2-1 of the main air duct 2-5, but also has the air inlet direction consistent with the air outlet direction . Certainly, the first opening of the main air duct 2-5 can also be formed by setting the shape of the side surface and the bottom surface of the cabinet to form the air intake in the direction of 360 degrees. Here, no further detailed description will be given. Other parts of the third embodiment are the same as those of the first embodiment, and will not be repeated here.

Abstract

A heat-dissipating system for high-power cabinet is provided, which comprises: a cabinet; at least one main air duct, which is formed in the cabinet with a first opening and a second opening, and a first heat-generating assembly, a second heat-generating assembly and at least one first fan, which are mounted in the at least one main air duct, wherein the first fan is mounted between the first heat-generating assembly and the second heat-generating assembly; and the outlet of the first fan faces the first heat-generating assembly, airflow enters the main air duct from the first opening of the main air duct, flows through the second heat-generating assembly, an inlet of the first fan, an outlet of the first fan, and the first heat-generating assembly in sequence, and finally is discharged out of the cabinet from the second opening of the main air duct cabinet.

Description

technical field [0001] The invention relates to a high-power cabinet cooling system and a static reactive power compensation system. Background technique [0002] In the cabinet heat dissipation system of high-power IGBTs, reactors and other heating elements, since the components emit a large amount of heat during the working process, if the heat cannot be dissipated in time, it is easy to cause damage to the components due to excessive temperature. Therefore, the heating elements The layout of the air duct and the reasonable design of the air duct become very important. [0003] See figure 1 , the traditional high-power cabinet cooling system includes: a cabinet 1-6, a first air duct 1-9 formed in the cabinet 1-6, a first fan 1-8 placed in the first air duct 1-9, and a first Heating components 1-10. Wherein, the first air channel 1-9 has a first air inlet 1-11 and a first air outlet 1-7, the first air inlet 1-11 is arranged on the side of the cabinet 1-6, and the first a...
