Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the utility model provides a kind of air-cooled converter cabinet with inner loop system, comprise the cabinet for installing convertor equipment, main chamber 1 and two secondary cavities 2 are provided with in cabinet, main chamber 1 and two secondary cavities 2 are disposed adjacent and are separated by by chamber wall, main chamber 1 both ends open forms the main air duct be in communication with the outside, and one end of main chamber 1 is provided with the main air blower 3 for driving air flowing in main air duct; Two secondary cavities 2 are located at the both sides of main chamber 1 respectively, and two secondary cavities 2 are communicated with the secondary air channel making to form inner loop between two secondary cavities 2 by two ventilation slots 4, and ventilation slot 4 place is provided with the Inner eycle blower fan 5 for driving air flowing in time air channel.The devices such as the reactor 7 that caloric value is very large and transformer 8 are set directly in main chamber 1, and the devices such as the device cell 9 higher to sealing requirements and power cell 10 are arranged in two secondary cavities 2 sealing with the external world.
When converter cabinet operates, main chamber 1 and the interior unsteady flow components and parts arranged of secondary cavity 2 can produce amount of heat, the amount of heat that the device cell 9 in two secondary cavities 2 especially sealed and power cell 10 distribute, and can conduct on the wall of chamber.After air enters main air duct by one end air inlet of main chamber 1, the relatively low air of temperature directly flows through reactor 7, transformer 8 and chamber wall in main chamber 1, take away the heat that reactor 7, transformer 8 and chamber wall distribute, discharge outside main chamber 1 through main air blower 3 by air outlet again, carry heat in main air duct is gone out cabinet, reaches the effect of cooling.Air in two secondary cavities 2 of sealing is due to the driving by Inner eycle blower fan 5, formed in time air channel through two ventilation slots 4 and carry out inner loop flowing, hot-air in secondary air channel constantly and chamber wall carry out exchange heat, by heat conduction on the wall of chamber, temperature in secondary cavity 2 is reduced, form an internal heat dissipating circulation, simultaneously because main chamber 1 and two secondary cavities 2 are disposed adjacent and are separated by by a chamber wall, gone out cabinet by the airstrip flowed through in main air duct when conducting to the heat postscript on the wall of shared chamber, reach the effect of cooling.
By arranging main air duct, by forced air cooling high power device being dispelled the heat and reaching the effect of cooling; By arranging time air channel, form the internally air-cooled circulatory system of annular seal space, air in the secondary cavity 2 of sealing is moved along Inner eycle time air channel, significantly can improve device in secondary cavity 2 and inner air, exchange rate between inner air and chamber wall, fast the heat that device produces is dispersed into outside chamber, effective elimination hot localised points, reduces in-cabinet temperature, solves the contradiction between converter cabinet sealing and internal components heat radiation.
In the present embodiment, the baffler 21 for guiding internal gas flow to flow is provided with in secondary cavity 2.Baffler 21 according to the heating feature of device in cabinet, can be arranged in conjunction with cabinet wall, and to improve the secondary air channel of Inner eycle further, the flowing of specification air-flow, cooling-down effect is better.
In the present embodiment, be provided with more than one radiator 6 in main chamber 1, radiator 6 is connected with the power cell 10 in secondary cavity 2 for most of heat conduction of being produced by power cell 10 in main chamber 1.By arranging radiator 6, quick to the device cooling in secondary cavity 2 further, better effects if.
Below be only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, protection range of the present utility model should be considered as.
