[0024] Furthermore, cooling fans 6 are provided on both sides of the heat dissipation device body 1, and a vent 7 is provided on the top of the heat dissipation device body 1;
[0025] Specifically, the vent 7 allows wind in the air to enter therefrom, and then enters the inside of the instrument device body 2 from the heat dissipation port 12, thereby improving the heat dissipation inside the instrument device body 2 through ventilation.
[0026] It should be noted that during ventilation, when wind enters the interior of the instrument device body 2 , dust in the wind will be blocked on the dustproof net 10 , thereby preventing dust from damaging electronic components inside the instrument device body 2 .
[0027] Furthermore, a clamping groove 11 is provided on the back of the slide groove 3 , and a clamping block 8 is provided on the back of the slider 4 . The clamping block 8 is connected to the clamping groove 11 in a clamping manner.

[0029] Working principle: The utility model is a heat dissipation device for an electric meter, in which a heat conduction plate is arranged inside the meter device body 2, the heat conduction plate is in contact with the electrical equipment inside the meter device body 2, and a heat dissipation fin 9 is arranged on the front side of the heat conduction plate, and the other end of the heat dissipation fin 9 is located on the side of the meter device body 2. During the operation of the meter device body 2, the heat generated by the electronic device is introduced into the heat dissipation fin 9 through the heat conduction plate, and the heat is dissipated by the wind through the heat dissipation fan 6 in the heat dissipation device body 2, thereby further improving the heat dissipation efficiency of the meter device body 2.
[0030] In addition, by setting a slider 4 at the front end of the bottom of the instrument device body 2, a slide groove 3 is opened at the bottom of the heat dissipation device body 1. When fixing the instrument device body 2, the slider 4 is first engaged with the slide groove 3, and then the instrument device body 2 is pushed by the push-pull rod 5. When the instrument device body 2 is pushed to the back of the slide groove 3, the block 8 behind the slider 4 will be snap-connected to the slot 11, so that the instrument device body 2 is fixed to the heat dissipation device body 1.
