Detailed Description

The following describes the electronic box of a temperature controller according to the present invention in detail with reference to the attached drawings.

As shown in fig. 1 and fig. 2, do the utility model discloses an electronic box of temperature controller, the electronic box includes electronic box body 1, be equipped with trompil 12 on electronic box body 1's the front bezel 11, be equipped with fin 2 on the outer wall of front bezel 11, electronic box body 1's inside is equipped with solid state relay 3, fin 2 with solid state relay 3 passes through trompil 12 heat conduction is connected.

The area of trompil 12 is less than the surface area of fin 2, fin 2 sets up at the 11 outer walls of front bezel of electronic box body 1, covers trompil 12 on the front bezel 11, be equipped with the mounting hole on the fin 2, be equipped with the mounting hole on the front bezel 11, first mounting passes on the mounting hole is connected to the front bezel 11 of electronic box body 1 with fin 2, first mounting is the bolt.

The solid-state relay 3 is arranged inside the front plate 11 of the electric box body 1 and connected to the radiating fins 2, the solid-state relay 3 is provided with mounting holes, the radiating fins 2 are provided with mounting holes, the second fixing piece penetrates through the mounting holes to connect the solid-state relay 3 to the radiating fins 2, and the second fixing piece is a bolt.

A heat conduction layer is arranged between the radiating fin 2 and the solid-state relay 3, and the heat conduction layer is a heat conduction fin made of graphite; or the heat conduction layer is made of heat conduction paste.

It should be noted that when no heat conductive layer is provided between the heat sink 2 and the solid-state relay 3, the solid-state relay 3 relies on direct contact with the heat sink 2 to conduct heat to the heat sink 2. Because the fin 2 is the aluminium material, after using for a certain time, the surface pit probably appears, makes the area of contact between fin 2 and the solid state relay 3 reduce to reduce heat conduction efficiency. Therefore, the arrangement of the heat conduction layer can fill the pits and increase the contact area between the pits and the heat conduction layer, so that the heat conduction efficiency of heat is improved, and the heat generated in the operation process of the solid-state relay is more quickly conducted to the radiating fins.
