Charging terminal radiating control system

Abstract

The invention discloses a charging terminal radiating control system. The charging terminal radiating control system comprises a temperature detection system, a control system and a fan, wherein the temperature detection system and the fan are connected with the control system respectively; the temperature detection system comprises one or more temperature sensors, the temperature sensors are distributed at heating positions, the temperature sensors are used for carrying out temperature detection and converting detected temperature into output signals, and output signals comprise analog quantity signals and digital signals; the control system is used for carrying out temperature detection input conversion, error discrimination, temperature correction, core PID algorithm, PWM wave output, temperature parameter reporting and fan parameter reporting, and real-time communication is realized between the control system and an upper computer; and the fan is a PWM controlled axial fan. Throughthe manner, the radiating effect, temperature maintaining capacity and energy consumption noise can be balanced effectively, the energy consumption and noise are realized effectively while good radiation is realized, and the system has the advantages of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the field of heat dissipation control systems, in particular to a heat dissipation control system for a charging terminal. Background technique [0002] At present, charging terminal equipment has been gradually spread and used in communities, schools, and express outlets. The charging terminal is deployed outdoors, and the working environment is harsh. The summer temperature is high and the heat generated during charging will cause the temperature inside the charging terminal to rise sharply. , high temperature will make the battery more flammable and explosive, and charging fire incidents emerge in endlessly. Hydrogen discharge equipment is also an essential content; the charging temperature of the battery is 0-45°C, if it is used in a colder season, a scattering system is required to reduce the heat dissipation capacity, so as to ensure that the temperature will not drop significantly while discharging hydrogen, which will a...

AI Technical Summary

Problems solved by technology

However, the heat dissipation control system of the above charging terminal has the following problems: the air volume of the fan has not been calculated in detail, the selection of the fan is obviously too small, and the heat dissipation effect is poor

Without a temperature sensor, the open-loop control logic cannot balance the cooling effect and energy consumption noise, resulting in waste of energy consumption and a lot of noise
