Abstract: A rack type data center includes a rack, a column of servers and an air conditioner module. A server room and an air conditioner room are formed in the rack. A primary inlet valve is disposed on the server room, and an outlet valve is disposed on the server room. An inlet fan is arranged between the server room and the air conditioner room; the servers are arranged in the server room; a cold aisle and a hot aisle are formed in the server room, and the inlet fan is arranged corresponsive to the cold aisle. The air conditioner module includes a coil installed in the air conditioner room, and the primary inlet valve is disposed between the coil and the inlet fan. The outlet valve is used to exhaust air in the hot aisle. The fan introduces airflow into the cold aisle without passing through the coil.

Abstract: A power adapter includes a main body, a locking member and a power cable coupler head. The main body includes an opening. The locking member is arranged on the main body and includes a perforation, which is communicated with the opening. The power cable coupler head is rotatably and detachably connected to the locking member such that a portion of the power cable coupler head is penetrated through the perforation and the opening to be coupled with the main body.

Abstract: The embodiment of the present invention provides a joint clock source coupling architecture of a time division duplex (TDD) transceiver to minimize a circuit element interference and stabilize a performance of a circuit element within the TDD transceiver. Thereby, a communication link of the TDD transceiver is ensured, and a throughput of the TDD transceiver is increased.

Abstract: A base unit of an electric cooking device includes a grill plate that has front and rear edge portions opposite to each other along a plate axis. An oil-collecting hole is formed adjacent to the front edge portion. The grill plate has a top cooking surface that inclines rearwardly and upwardly from the front edge portion to the rear edge portion, that inclines downwardly from the plate axis to left and right edge portions of the grill plate, and that is formed with a plurality of curved grill ribs, each of which includes a portion extending from the left side of the oil-collecting hole to the plate axis, and a portion extending from the plate axis to the right side of the oil-collecting hole.
