New energy vehicle testing comprehensive test box filled with heat transfer oil

In order to ensure the correct operation of the machine, the new energy vehicle inspection integrated test box must ensure that no air bubbles remain in the system, ensure that the heat transfer medium outlet is connected to the lower interface of the reactor, and the heat transfer medium inlet is connected to the upper interface of the reactor. When filling the heat-conducting medium, care must be taken to prevent the heat-conducting medium from overflowing to the upper cover and overflowing to the upper cover liquid, which may cause the thermal conductive medium to leak into the electrical equipment of the device, which may cause short circuit of the device, electrical failure, and control system failure; if the thermal medium is Flammable and explosive, may cause burning and explosion.

New energy vehicle testing integrated test box equipment power supply adopts three-phase four-wire system 380V 50HZ 60HZ 3 fire lines, one zero line, one ground line, the new energy vehicle test comprehensive test box must be grounded, the new energy vehicle test comprehensive test Power on the box and check if the continuity is correct (the continuous indicator lights up in green). If the continuity is not correct, please switch any two live lines until it is correct.

Before the thermal energy filling of the new energy vehicle testing comprehensive test box, the thermal fluid inlet of the new energy vehicle testing integrated test box is connected with the stainless steel bellows at the upper end of the reactor, and the heat transfer oil outlet of the new energy vehicle testing comprehensive test box is The heat transfer oil inlet at the lower end of the reactor is connected by a stainless steel bellows. Then open the exhaust valve directly above the new energy vehicle detection integrated test box equipment and open the filling port. New energy vehicle detection integrated test box heat injection into the filling port, turn on the power, press the dosing button (the system will automatically remove the air), 30 seconds apart, turn off the dosing button (continuously add thermal media during the process, Until the system exhaust valve hears the heat transfer medium back to the dosing tank). After filling the entire circulation system with the heat transfer medium, the expansion tank level index position is at the liquid level (when the system has basically eliminated the air), then close the exhaust valve, then turn off the dosing button and turn on the operation button. Set the temperature to 150 degrees and continue to vent. After reaching 150 degrees, run for about 5 minutes and reset the temperature to 25 degrees. After the target value is reached, it can be basically regarded as the system air.

The heat transfer oil of the new energy vehicle test comprehensive test box is not suitable for all heat transfer oils. It is recommended that users ask for the types of heat transfer oil suitable for the new energy vehicle test comprehensive test box, and then select the heat transfer oil.
