Abstract

The invention discloses a temperature control system for an outdoor control cabinet. The temperature control system comprises a control cabinet, a power supply, a core control plate, a temperature sensor, a flexible heater and an aerofoil fan. The temperature control system for the outdoor control cabinet is characterized in that the core control plate of the temperature control system for the outdoor control cabinet, the temperature sensor arranged in the control cabinet, and the flexible heater and the aerofoil fan which are arranged on a wall of a shell of the control cabinet are arranged on a circuit control plate or an inner wall inside the shell of the control cabinet; ambient temperature which is detected by the temperature sensor is monitored by the core control plate in real time and is displayed through a nixie tube display unit; a singlechip controller starts the aerofoil fan or the flexible heater to reduce or raise the temperature when the ambient temperature is greater than a high-temperature warning value or smaller than a low-temperature warning value which is set on the singlechip controller, so that representative equipment in the outdoor control cabinet is ensured to be positioned in temperature environment of normal work.

Description

technical field [0001] A temperature control system for outdoor control cabinets, which monitors the temperature changes in the control cabinet in real time, automatically starts and stops the cooling fan or flexible heater to adjust the temperature in the control cabinet, and ensures the normal operation of the instruments or equipment in the cabinet. Background technique [0002] In hot and cold regions, the temperature of instruments, solenoid valves and other equipment in the industrial field control cabinet is too high or too low, which often leads to a large linear error of the instrument or the solenoid valve cannot be opened and closed normally due to insufficient lubrication due to low temperature, thus affecting normal industrial production. Contents of the invention [0003] The purpose of the present invention is to provide a temperature control system for an outdoor control cabinet, which can automatically adjust the temperature inside the control cabinet acco...
