Description
Technical field
This utility model relates to electrical control cabinet technical field, particularly to one for high-power switch board
Heat abstractor.Further relate to the switch board of a kind of this heat abstractor of application.
Background technology
In production practices, much equipped with the switch board open air to be placed on of large power semiconductor device, for
Control circuit in protection switch board, semiconductor components and devices etc. are by outdoor rainwater, dust, corrosivity
The destruction of gas, switch board must possess the highest degree of protection, such as IP54 or higher.It means that control
The sealing of cabinet processed to be got well, and could prevent water, dust etc. from entering.But the most advanced switch board is increasingly
How to use large power semiconductor device (such as IGBT module) conduct switch, and be operated in higher switch lock
Under rate.When these large power semiconductor devices are operated in high frequency, power consumption is very big, can produce the biggest
Heat, if these heats can not dissipate in time, can cause device to be damaged, so, it is desirable to high-power control
Cabinet processed can preferably dispel the heat.Therefore, switch board heat radiation and switch board closed protective constitute conflict,
The closed protective of switch board should be ensured, ensure that the heat radiation of switch board is a problem being difficult to balance simultaneously.
Solution the most typical, effective is to use heat exchanger, and Fig. 1 is of the prior art one
Plant the schematic diagram of the heat dissipating method of high-power switch board, i.e. in airtight control cabinet 01, fill one or many
Individual air heat exchanger 04, the heat that the electric equipment 02 controlled in cabinet 01 is produced is handed over by air heat
Parallel operation 04 " exchange " is to controlling outside cabinet 01, and air heat exchanger 04 is air insulated, i.e. controls
Air in cabinet 01 and the air controlled outside cabinet 01 are isolations, and cabinet top is generally fitted with blower fan 03 and enters
The agitation of air in row control cabinet 01.So achieve that the most airtight but also dispel the heat, efficiently solving big
Should the airtight contradiction fully dispelled the heat again when power switch board uses out of doors.
But the weak point that this method exists is: the heat that power device sends first is dispersed into switch board
Body 01 is internal, and the air within computer heating control cabinet 01, then by 04 inner air of air heat exchanger
Heat change to control in the environment outside cabinet 01, now control air cabinet 01 within and carry heat and pass
Pass the effect of medium.Owing to air is very poor as the capacity of heat transmission of heat transfer medium, and thermal resistance is relatively big, power
It is outside that the heat that device produces can not be dispersed into control cabinet 01 in time, and heat is easily accumulated in power device
Part is internal and controls, in cabinet 01, to cause power device by high temperature failure.
In sum, the most not only ensure the closed protective of high-power switch board but also can effectively dispel the heat,
Become those skilled in the art's problem demanding prompt solution.
