The following description of the embodiments of the present invention will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 to 7, an electric cabinet for alpine regions comprises an outer cabinet 1 and an inner cabinet 2, wherein the inner cabinet 2 is arranged in the outer cabinet 1, and the outer cabinet 1 and the inner cabinet 2 are respectively provided with a door body; the electric cabinet can be arranged by adopting a common electric cabinet structure in the prior art; the inner box body 2 is fixed in the outer box body 1. An upper air outlet 3 and a lower air inlet 4 are arranged on one side of the inner box body 2, the upper air outlet 3 is positioned above one side of the inner box body 2, and the lower air inlet 4 is positioned below one side of the inner box body 2. The electronic components are arranged in the inner case 2.
The upper air outlet 3 is communicated with a first air outlet pipe 5, and the upper end of the first air outlet pipe 5 passes through the outer box body 1 to extend out; a first fan 6 is arranged at the upper air outlet 3; the air flow in the inner casing 2 can be led out to the outside (atmosphere) by the first fan 6.
An air inlet pipe 7 is communicated with the lower air inlet 4, the upper end of the air inlet pipe 7 passes through the first air outlet pipe 5 and the outer box body 1 to extend out, and a second fan 8 is arranged at the upper end of the air inlet pipe 7; the external cool air may be introduced into the inner case 2 through the second fan 8.
A part of the air inlet pipe 7 is positioned in the first air outlet pipe 5, and the air inlet pipe 7 of the part can absorb the heat of the air discharged from the first air outlet pipe 5; meanwhile, a heating device 9 is sleeved outside the air inlet pipe 7, and the air in the air inlet pipe 7 is heated through the heating device 9.
When preheating is started: the heating device 9 operates, and external cold air is introduced through the second fan 8 and enters the inner box body 2 after being heated by the heating device 9, so that the electronic components in the inner box body 2 are preheated, and the normal starting of the electronic components is ensured. Meanwhile, in the preheating process, hot air in the inner box body 2 can be discharged through the first air outlet pipe 5 under the action of the first fan 6; moreover, since part of the air inlet pipe 7 is positioned in the first air outlet pipe 5, after the external cold air enters the air inlet pipe 7, the residual heat of the air discharged by the first air outlet pipe 5 can be absorbed to heat the air, and then the temperature of the air is further increased by the heating device 9. Therefore, through the structure setting, when guaranteeing to start preheating to electronic component, can also realize the ventilation to interior box 2 inside, avoid interior box 2 inside moisture too big.
When the electronic element starts to start to operate, certain heat is generated during the operation; at this time, the heating device 9 may be turned off.
