Remarks

Cooling

After the TEC applies a positive voltage to semiconductor refrigeration chips, the internal circulation side becomes cold, and cold air is supplied to the cabinet through the cold-end heat sink. The external circulation side becomes hot, and heat is dissipated through the hot-end heat sink.



Heat is transferred from the cold end to the hot end to realize refrigeration



The controller controls the fans and semiconductor refrigeration chips, monitors the TEC04 operation, and generates an alarm when a fault occurs.



Fans provided forced air in both cold end and the hot end, which speeds up heat dissipation from the heat sink.

Heating

After the TEC applies a negative voltage to semiconductor refrigeration chips, the internal circulation side becomes hot, and heat is supplied to the Mini-shelter through the cold-end heat sink. The external circulation side becomes cold, and heat is dissipated into the Mini-shelter through the hot-end heat sink.

5.3 Cable Layout Principle The AC power cable to the mains is routed into the power distribution equipment compartment from the bottom of the cabinet to connect to the AC power distribution device. Communications cables such as the intermediate frequency cable and feeder are routed into the equipment compartment from the upper part of the compartment side panel. Then the communications cables are routed along columns of the rack to connect to devices. Cables in each compartment are routed along the rack. Cables are routed between compartments by using cable holes reserved on the wall board. Figure 5-1 shows the cable layout of the Mini-shelter.
