AI Technical Summary

Technical Problem

The heat dissipation channels of existing electricity meters are designed to be open, resulting in a non-sealed operating environment. External solid and liquid media can easily penetrate, affecting the reliability and safety of the metering device.

Method used

It adopts a closed shell structure, combined with a heat conduction part and a fan system. It conducts heat through the closed environment and actively dissipates heat using the fan, forming a closed heat dissipation channel. A dust filter plate is installed at the air outlet to block solid particles, thus achieving efficient heat dissipation.

Benefits of technology

This achieves a closed operating environment for the electricity meter, preventing the intrusion of solid and liquid media, and improving heat dissipation efficiency, as well as the reliability and safety of the device.

Abstract

The utility model discloses an integrated electric energy meter shell belongs to electric energy meter technical field, this integrated electric energy meter shell includes first casing and second casing, first casing is used to install the module required for running, and second casing is fixed on first casing, and first casing and second casing combination form the cavity. Among them, the heat conduction part is provided on the first casing, and the first air port and the second air port are equipped with on the second casing, and the first air port and the second air port all communicate the cavity and form the heat dissipation channel. The utility model has the advantages that: the utility model passes through the heat conduction part, and the heat generated in the module running in the first casing is conducted to the second casing, and then the heat is conducted to the outside of the second casing through the heat dissipation channel, to complete heat dissipation, and this kind of heat dissipation mode makes the running module in the first casing not to produce direct contact with the outside, to avoid the problem such as dust accumulation, rainwater leakage causes short circuit, and further improves the operation performance of integrated electric energy meter.
