Heat dissipation includes air-cooled, water cooling and oil cooling etc. used by the rack of convertor equipment；Wherein, constrained, put by environmental condition
The rack for putting convertor equipment out of doors typically uses wind-cooling heat dissipating.
Fig. 1 and Fig. 2 is the structural representation of the rack of the outdoor convertor equipment of prior art, including cabinet body 1 and position
Tarpaulin 2 directly over cabinet body 1, is provided with the 3rd air outlet 15, cabinet body between tarpaulin 2 and cabinet body 1
Bottom surface be provided with the 3rd air inlet 14, other electric elements such as convertor equipment and capacitor, controller are arranged on rack sheet
The inner chamber of body 1.The top of cabinet body 1 is provided with blower fan, and blower fan produces an air-flow from bottom to top in cabinet body 1,
Air-flow enters to be shunted and is flowed through respectively from the surface of each electronic component naturally after the 3rd air inlet 14, and air-flow takes away electronic component
Caused heat simultaneously leaves cabinet body from the 3rd air outlet 15.
The defects of rack of the outdoor rheology equipment of this prior art, is：1. each electronic component quantity of heat production in rack
Not consistent, heat caused by modular convertor equipment will be far longer than the generation of the auxiliary electronic elements such as capacitor, controller
Heat；But the relative equilibrium after shunting naturally of radiating airflow caused by blower fan flows through from the surface of each electronic component,
This causes the radiating effect relative deficiency of convertor equipment, and prior art is in order to meet that the radiating requirements of convertor equipment must be from entirety
The power of upper increase blower fan.2. the airflow direction in rack is from bottom to top, hot-air is easily accumulated at the top of rack, makes
The upper temp for obtaining tarpaulin and cabinet body is continuously increased, and is unfavorable for the radiating of rack.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of new rack for being used to install convertor equipment, for mould
The convertor equipment emphasis radiating of block, reduce the power of blower fan；Meanwhile prevent interior of equipment cabinet hot-air from accumulating.
In order to solve the above technical problems, the technical solution adopted in the utility model is：It is a kind of for air-cooled convertor equipment
Rack, including cabinet body and independent ventiduct, the first air inlet and the first air outlet, the first air inlet are provided with cabinet body
Upper, the first air outlet should be typically designed the first air outlet in the bottom of cabinet body, to keep whole radiating airflow under
The path circulated in rack is straight down.
Installation convertor equipment inside cabinet body, current convertor equipment are generally modular construction, inside convertor equipment
With the gas channel to be circulated for radiating airflow and the second air inlet and the second air outlet that are arranged on gas channel both ends, peace

Distribution, meet the radiating requirements of different electronic components, reduce the power of blower fan；
On the other hand, the flowing of hot-air from bottom to top as caused by the electronic components such as capacitor, controller, blower fan produce
Radiating airflow be top-down, the hot and cold air of two bursts of relative directions is sufficiently mixed in the inner chamber of cabinet body and from radiating
Mouth overflows, and can effectively prevent hot-air from being accumulated on the top of cabinet body.
Further, the cabinet body is arranged above tarpaulin.
Further, the tarpaulin is saddle roof shape.
Further, the heat emission hole is located at the relatively low position in cabinet body side, and this is to allow in the second air channel
Hot and cold air has larger space, to be sufficiently mixed.
Further, the heat emission hole is water proof type heat emission hole, i.e., the top of each heat emission hole is set by a rainshed
Cornice, prevent rainwater from entering interior of equipment cabinet.
Further, it is provided with Air Filter at first air inlet, the first air outlet and heat emission hole.
Beneficial effect：(1) inner chamber of cabinet body is divided into two air channels by rack of the present utility model, and the first air channel is special
The convertor equipment radiating big for caloric value, the second air channel are used for the electronic components such as the less capacitor of caloric value, controller and dissipated
Heat, radiating airflow caused by blower fan are mostly used in radiating convertor equipment, and small part is used for the electronics such as capacitor, controller that radiate
Element, radiating airflow distribution is more reasonable, and the utilization ratio of blower fan is high, helps to save.(2) rack of the present utility model is by height
The electronic component such as the convertor equipment of caloric value and the capacitor of lower calorific value, controller uses different air duct radiations, avoids height
The element of the elements affect lower calorific value of caloric value, it is more beneficial for the work of each electronic component lasting stability.(3) this practicality is new
The flow direction of radiating airflow in the rack of type is top-down, and the flow direction of radiating airflow and hot-air is on the contrary, just
It is sufficiently mixed in hot and cold air, prevents hot-air from being accumulated in the corner of rack upper space.(4) top of rack of the present utility model
Portion is provided with the tarpaulin of saddle roof shape, for outdoor water-proof.(5) rack of the present utility model is in the first air inlet, first
Air Filter is provided with air outlet and heat emission hole, prevents dust, rainwater etc. from entering rack inner chamber.
