The invention discloses a vacuum high-temperature furnace cooling intelligent control system and a control method thereof, relates to the field of high-temperature furnace cooling regulation and control, and solves the problems that an existing high-temperature furnace temperature monitoring and control method is low in accuracy and difficult to accurately control. The temperature detection module is used for detecting the water supply temperature in real time and feeding back a temperature detection signal; the flow detection module is used for detecting the water return flow in real time and feeding back a flow detection signal; the cooling control module is used for receiving and responding to the temperature detection signal and the flow detection signal so as to control the cooling water system to regulate and control operation parameters; according to the intelligent cooling control system for the vacuum high-temperature furnace and the control method of the intelligent cooling control system, accurate temperature and flow information can be obtained through detection, operation parameters can be adjusted in time in real time, and normal operation of a cooling water system is guaranteed.
