Abstract

The invention relates to a heat dissipation intelligent control system of a high-power combined load and a control method of the heat dissipation intelligent control system. The system includes a heat dissipating fan. The system comprises a heat dissipating air duct which is connected with the heat dissipating fan; the heat dissipating air duct is provided with an isolation net, a heat dissipating fan array and an electric louver sequentially; the heat dissipating fan and the heat dissipating air duct are both connected with a control mechanism; and the control mechanism includes a CPU, a PLC and a signal acquisition system. According to the method, the control mechanism controls the switching on and switching off of the electric louver at an air inlet; the signal acquisition system of the control mechanism acquires the power of the load; the CPU calculates required air feed quantity through an intelligent control algorithm so as to determine the output power, number and combination mode of required fans; the combination and conversion of the fan array are controlled; and therefore, a variable heat dissipation control mode can be realized. With the heat dissipation intelligent control system and the control method provided by the invention adopted, the heat dissipation efficiency of the load can be effectively improved, and therefore, the normal operation of the large-power combination load can be ensured, and the power consumption of a system can be reduced.

Description

Technical field: [0001] The present invention relates to a heat dissipation intelligent control system and a control method thereof, and more particularly to a high-power combined load heat dissipation intelligent control system and a control method thereof. Background technique: [0002] High-voltage and low-voltage high-power power supply systems, diesel generator sets, transformers, communication power supplies, uninterruptible power supplies (UPS), large-capacity battery packs and other equipment widely use high-power combined loads to test their power, electrical performance, aging and reliability, etc. performance. Traditional high-power combined loads generally adopt constant wind speed and quantitative forced air cooling. The heat dissipation effect of forced air cooling is 10-20 times that of natural air cooling. It is mainly realized by high-power cooling fans. The air volume of cooling fans must reach the load heat dissipation. 1.2 to 1.5 multiples can meet the h...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the quantitative temperature-controlled fan cooling system, when the simulated load is loaded, all the fans are turned on; and when the load is reduced, the number of cooling fans cannot be reduced according to the actual cooling needs, and the cooling fans themselves have large power and a large number , which will result in an increase in the overall power consumption of the simulated load and a serious waste of electric energy;

[0005] (2) Due to the large internal space of the high-power combined load, the heat generation at each point is uneven, and the heat dissipation effect is not good, which may easily cause local long-term overheating of the load, thereby reducing the service life of the load;

[0006] (3) A large number of high-power fans are used to generate large noise and strong vibration, which is harmful to the entire high-power combined load system
