In some embodiments, referring to fig. 6, the heat dissipation structure of the meter box further includes a flow baffle 403, the flow baffle 403 is substantially U-shaped, the inner base 202 is plate-shaped, the side edges and the bottom edge of the left and right sides of the inner base 202 are connected to the inner end of the flow baffle 403, and the outer end of the flow baffle 403 is connected to the outer base 102. Here, "inner end" and "outer end" are also the same concept with respect to the instrument cavity 301, and the end of the baffle plate 403 closer to the instrument cavity 301 is the inner end (which may correspond to the rear end of the baffle plate 403 in fig. 4), and the end of the baffle plate 403 relatively far from the instrument cavity 301 is the outer end (which may correspond to the front end of the baffle plate 403 in fig. 4). The baffle plate 403 connects the inner grid 201 and the outer grid 101 to form the installation cavity 302, and the baffle plate 403 serves as a part of the wall surface of the installation cavity 302 and can be used for blocking water in the installation cavity 302 from flowing into the instrument cavity 301. The baffle plate 403 and the outer grid 101 may be connected by welding or by a threaded fastener such as a screw. An opening 303 is defined between the top of the inner grill 201 and the outer grill 101, and the dust screen 204 can enter and exit the installation cavity 302 through the opening 303. The dust screen 204 needs to be cleaned regularly, for example, dust and insect corpses are cleaned, and the opening 303 is arranged to facilitate the detachment and installation of the dust screen 204, which is beneficial to improving the maintenance efficiency of the dust screen 204.

Water passing through the first outer vent 404 and the second outer vent 401 from outside to inside is temporarily stored in the installation cavity 302, when the water in the installation cavity 302 accumulates to a certain amount, the water level rises, a large amount of water passes through the first inner vent 405 and the second inner vent 402 to enter the instrument cavity 301, and the water resistance of the heat dissipation structure of the meter box is disabled. To avoid this problem, in some embodiments, the bottom of the outer base 102 further defines a drainage hole 104, the drainage hole 104 is communicated with the installation cavity 302, and water in the installation cavity 302 can drain out of the installation cavity 302 through the drainage hole 104.
