Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1-5, a special digital display module heat dissipation structure for an overvoltage and undervoltage protector comprises a shell 1, a chip board module 2, a protection window 3 and a fin frame 4;

a window 11 is arranged on the shell 1, the shape of the protection window 3 is consistent with that of the window 11, and a first air port 31 and a second air port 32 are respectively arranged at the upper part and the lower part of the protection window 3; the chip board module 2 comprises a circuit board 21 and a digital display block 22; the chip board module 2 is detachably fixed in the shell 1, and the position of the digital display block 22 on the chip board module 2 is matched with that of the window 11.

The protection window 3 is fixedly connected with the fin frame 4 in an adhesion mode. The fin frame 4 includes a frame 42 and a plurality of fins 41 provided on an outer wall of the frame 42; the frame body 42 is sleeved with the digital display block 22 to form matching fit; the data on the digital display block 22 can be read through the window 11 on the housing 1. The digital display block 22 does not block the first air port 31 and the second air port 32.

The fins 41 are arranged in parallel to the protection window 3, and a gap is arranged between the fin 41 close to the end of the protection window 3 on the fin frame 4 and the protection window 3, so that air outlet and air inlet of the first air port 31 and the second air port 32 are ensured.

Limited by the light emitting principle of the digital display block 22, a light-scattering film needs to be attached to the display area of the digital display block 22 to ensure the display effect. However, the temperature of the digital display block 22 is increased by the heat generated by the operation of the digital display block 22 and the whole chip board module 2, which is disadvantageous to the attachment of the light-diffusing film sheet to the digital display block 22, and the light-diffusing film sheet is easy to form a raised edge or bubble, which affects the reading.

The fin frame 4 is sleeved outside the digital display block 22 to promote the heat dissipation of the digital display block 22; the introduction of the first air port 31 and the second air port 32 enhances the heat dissipation effect of the fin frame 4;

in a specific implementation, a heat conducting adhesive is arranged between the fin frame 4 and the digital display block 22 to enhance the heat transfer from the digital display block 22 to the fin frame 4.

In a specific implementation, the fin frame 4 is made of aluminum.

Example 2:

as shown in fig. 6 to 7, embodiment 2 is different from embodiment 1 in that the fin 41 is disposed perpendicular to the protection window 3, and the disposition of the vertical protection window 3 facilitates the air outlet and inlet of the first and

second ports

31 and 32, thereby enhancing the heat dissipation of the fin 41.

The first air port 31 is arranged against the upper part of the protection window 3, the second air port 32 is arranged against the lower part of the protection window 3, and compared with the design of an opening, the design of the position against which the protection window is arranged is convenient to process, and meanwhile, the strength is higher.
