Abstract: A refrigerating system include a heat management module, a direct cooling module, a plurality of heat exchange modules, and a plurality of cooling pipes. The heat management module may send, to the direct cooling module, control information that indicates that the charging pile needs to charge a terminal device. The direct cooling module may be configured to convert a gas refrigerant transmitted in a second pipe assembly into a liquid refrigerant, and transmit the liquid refrigerant to each heat exchange module and each cooling pipe through the first pipe assembly.

Abstract: A composite mouse assembly for a computer includes a mouse case. A computer interface encoder is contained in the mouse case. A positional sensor is connected to the interface encoder for controlling a screen indicator used for selecting menu items appearing on a display screen of the computer. A wireless remote control device is connected to the positional sensor and includes a plurality of user-activated direction control keys for transmitting digital serial encoded signals. A receiver unit is contained in the mouse case for receiving and amplifying the digital signals transmitted by the remote control device. A decoder is provided for interpreting the digital signals transferred by the receiver unit into one of a plurality digital direction control signals corresponding to the direction control keys of the remote control device. A converter converts the digital direction control signals to analog signals.
