The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, the main control box is schematically shown to include a box body 1, a box cover 2, a main control board 3, a heating element 4, a heat radiating member 5, and a heat conductive member 6. The current angle of fig. 2 is a structural diagram of the back of the box cover 2, that is, a structural diagram of the box cover 2 facing the box body 1.
In the embodiment of the present application, an opening (not shown) is preferably formed at an upper end of the case body 1, the case cover 2 is covered at the opening, a main control board 3 is disposed in the case body 1, and a heating element 4 is mounted on a surface of the main control board 3 facing the case cover 2. It can be seen that the heating element 4 is disposed on the upper surface of the main control board 3, wherein the heating element 4 is preferably fixedly mounted on the upper surface of the main control board 3 by welding.
It is understood that the number of the heating elements 4 may be plural.
A mounting through hole 21 is formed in the case cover 2 at a position corresponding to the heating element 4, and the heat radiating member 5 is disposed in the mounting through hole 21. The heat dissipation member 5 is detachably attached to the mounting through hole 21.
Specifically, the heat dissipation member 5 may be fixedly mounted in the mounting through hole 21 by means of a lap joint, a screw joint, a rivet joint, or a snap-fit connection.
Wherein the outer contour of the heat-dissipating member 5 is adapted to the inner contour of the mounting through-hole 21.
The heat-conducting member 6 extends from the heat-radiating member 5 toward the surface of the main control board 3 in the direction of the heating element 4, wherein the heat-conducting member 6 is in contact with the heating element 4. Specifically, in the present application, on the basis of the original main control box, according to the position of the heating element 4, a mounting through hole 21 is correspondingly formed in the box cover 2, a heat dissipation member 5 is additionally arranged in the mounting through hole 21, and the outer surface of the heat dissipation member 5 is in direct contact with air. Meanwhile, according to the distance between the upper surface of the heating element 4 and the lower surface of the heat radiating member 5, the heat conducting member 6 is mounted on the lower surface of the heat radiating member 5, and the heat conducting member 6 is made to contact with the heating element 4 on the main control board 3, so that the indirect connection between the heating element 4 and the heat radiating member 5 is realized by additionally arranging the heat conducting member 6 between the heat radiating member 5 and the heating element 4, and the heat generated by the heating element 4 can be transmitted to the heat radiating member 5 through the heat conducting member 6.
