2.4 Working Principles Figure 2-7 shows the conceptual diagram. AC power enters rectifiers through the AC power distribution unit (PDU). The rectifiers convert the AC power input into -48 V DC power output, which is directed by the DC PDU to DC loads along different routes. When the AC power is normal, rectifiers power DC loads and charge batteries. When the AC power is absent, rectifiers stop working and batteries start to power loads. After the AC power resumes, rectifiers power DC loads and charge batteries again. The SMU monitors the operating status of each component in the power system in real time and performs appropriate intelligent control. When detecting a fault, the SMU generates an alarm. The SMU monitors and regulates the temperature control unit based on the temperature measured by the temperature sensor to ensure the normal operating temperature for the cabinet.

3.6 Temperature Control Unit (for the TP48200A-HX09A3 and TP48200A-HX09A4) 3.6.1 Heat Exchange The equipment compartment of the power cabinet adopts heat exchanging to cool the equipment compartment, in which heat is exchanged through internal circulation and external circulation. Internal circulation: hot air in the equipment compartment is drawn by the internal fan into the heat exchanger, passes through the heat exchanging core from top to bottom, then releases heat to change to cold air, and finally returns to the equipment compartment through the internal air exhaust vent under the heat exchanger. External circulation: natural air outside the equipment compartment is drawn by the external fan into the heat exchanger via the equipment compartment, passes through the heat exchanging core from bottom to top, then absorbs heat to change to hot air, and finally flows out of the equipment compartment from the external air exhaust vent. Figure 3-20 shows the heat exchange working principles.

Working Principle

Cooling

The TCUA control box controls the refrigeration chip in the TEC module to cool the internal circulating air. The internal circulation fan draws the air inside the battery compartment into the internal circulation heat sink. The internal circulation heat sink cools the air and then returns the cooled air to the battery compartment through the air exhaust vents. Meantime, the external circulation fan draws natural air into the external circulation heat sink to accelerate the airflow. The air absorbs the heat

Function

3 Components

Working Principle from the external circulation heat sink and returns to the external environment through the air exhaust vents on the external circulation heat sink. The heat exchange between the internal and external environment is implemented so far.

Heating

The TCUA control box controls the refrigeration chip in the TEC module to heat the internal circulating air. The internal circulation fan draws the air inside the battery compartment into the internal circulation heat sink. The internal circulation heat sink heats the air and then returns the heated air to the battery compartment through the air exhaust vents. Meantime, the external circulation fan operates according to control logic and draws natural air into the external circulation heat sink. The air gives out heat and returns to the external environment through the air exhaust vents on the external circulation heat sink.
