Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples, and it is to be understood that the described examples are only a part of the examples of the present invention, and not all of the examples. The embodiments and features of the embodiments in the present application may be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the utility model.

It should be noted that if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

In addition, "a plurality" means two or more. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the utility model.

See fig. 1 and 2.

The utility model provides a heat abstractor of box-type substation, including the box body 1 that is used for holding electronic components, wind groove 11 has been seted up at the top in the box body 1, and the below of wind groove 11 is provided with fan 2, utilizes fan 2 to blow in the wind groove 11. Be provided with a plurality of wind channels 12 with this wind groove 11 intercommunication on the inner wall of box body 1, this wind channel 12 finally reaches the diapire of box body 1 through the roof and the lateral wall of box body 1, and a plurality of exhaust vents 13 have been seted up to the bottom surface of box body 1, and this exhaust vent 13 communicates with corresponding wind channel 12, and the wind in the wind channel 12 returns to box body 1 again from exhaust vent 13.

In the concrete implementation, fan 2 blows hot-blast to the wind groove 11 of box body 1, then get into each wind channel 12, hot-blast flows in wind channel 12, with heat transfer to the outer wall of box body 1 on, utilize the huge surface of box body 1 to dispel the heat, when taking the wind flow in wind channel 12 to the diapire of box body 1, the temperature has been got down this moment, blow in the bottom in the box body 1 through exhaust vent 13, dispel the heat and cool down for the inside electronic components of box body 1, the gas after the intensification is blown to the wind groove 11 by fan 2 once more, so circulation is reciprocal, improve the radiating efficiency of box-type substation.
