Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The present invention will now be described in detail with reference to the accompanying drawings.

The utility model provides a power module with initiative heat radiation structure, includes box 1 and case lid 2 of looks adaptation joint with it, divide into installing zone and radiating area with its inside through ventilating board 3 in the box 1, install fan 4 in the radiating area, install temperature sensor 5 with 4 electric connection of fan in the installing zone, 1 lateral wall cavity of box just has seted up a plurality of louvres 6, still install the adjusting device who adjusts 6 draught area of louvre in the 1 lateral wall of box.

As shown in the figure, when the installation is used, the installation of circuit element can be carried out to the installing zone, the radiating zone is then dispelled the heat to inside, under the normal condition, if equipment can carry out normal self-operation heat dissipation, adjusting device is then in the state of shutoff louvre 6, prevent the entering of dust, if circuit load grow, or because external factor causes the heat dissipation untimely, but the inside temperature variation of box 1 inside temperature sensor 5 real-time supervision, when the temperature risees, then signal control fan 4 opens, simultaneously control adjusting device changes 6 draught areas of louvre, thereby improve radiating efficiency.
