Description

technical field [0001] The invention belongs to the field of vehicle engineering, and relates to an organic heat carrier furnace system in performance tests of radiators of cooling systems of special vehicles. Background technique [0002] In the radiator performance test, it is necessary to heat the hot side medium oil, water, and air used in the radiator performance test to the required temperature, and stabilize the oil, water, and air temperatures within the set range. Generally, there are two kinds of heat sources for hot side medium oil, water, and gas, one is electric heating, and the other is organic heat carrier furnace. The use of electric heating is generally widely used in small-power radiator test benches, but the heat dissipation of armored vehicles is relatively large, and the use of electric heating is limited by power distribution indicators. Therefore, organic heat carrier furnaces are mostly used in high-power radiator test benches. The heat source used i...

Problems solved by technology

Because the temperature of the heat transfer oil fluctuates greatly, it is difficult to stabilize the water temperature at the specified ±0.2°C through PID control. Generally, the fluctuation range of the water temperature through PID control is ±1°C, and sometimes even exceeds ±2°C. Such a large temperature fluctuation cannot be satisfied. Heat balance accuracy requirements and control stability accuracy requirements for water radiators
