  • Publication number: 20250088032
    Abstract: A wireless charging module includes a module case, a fan, a coil assembly and a circuit board. The module case defines a first cavity and a second cavity and has a first side and a second side opposite to the first side. The second side defines an air outlet. The fan is disposed at the first side of the module case and configured to form an airflow S. The coil assembly is disposed in the first cavity, so that a first air channel is formed for the airflow S to pass through a first surface of the coil assembly. The circuit board is disposed in the second cavity and configured to form a second air channel allowing the airflow S to pass through a first surface of the circuit board and a third air channel allowing the airflow S to pass through a second surface of the circuit board. The airflow S passes through the first air channel, the second air channel and the third air channel and flows out of the wireless charging module from the air outlet.

  • Publication number: 20140284923
    Abstract: A pipe coupling has a lashing ring, a fastening screw and a gap shield. The lashing ring is mounted around a junction where two pipes are telescoped together. The fastening screw fastens two ends of the lashing ring. The gap shield is mounted on an inner surface of the lashing ring and covers a gap defined between the two ends of the lashing ring. With the gap shield covering the gap, when a fluid with high pressure flows through the pipes, the pipes do not deform at a part corresponding to the gap. Consequently, the fluid does not leak from the gap.

  • Publication number: 20140110095
    Abstract: A heat-dissipating apparatus has a cooling tube, a tubular conductor and a heat sink. The cooling tube has a body and an inlet and an outlet formed on the periphery of the body and communicating with an inner space of the body. The tubular conductor is mounted in the cooling tube with an outer surface of the tubular conductor engaging the inner rim of each open end to seal the open ends and defining a cooling chamber between the inner wall of the body and the tubular conductor. The heat sink is mounted inside the tubular conductor, and has multiple fins formed by continuously folding a metal sheet in a corrugated and annular form and abutting against an inner wall of the tubular conductor. The heat-dissipating apparatus increases the contact area between the heat sink and the tubular conductor and cooling channels, thereby providing a more satisfactory cooling effect.

  • Patent number: 7370812
    Abstract: A control device of a vehicle radiator system mainly has a temperature comparator, a temperature sensor, a keyboard and a display. The temperature sensor is positioned near an engine of the vehicle and outputs a detecting signal to the temperature comparator. Since the temperature comparator has a preset temperature value, the temperature comparator compares the preset temperature value with a current temperature value in the detecting signal to determine whether a start signal is output to a water gate driver device and a fan driver to open the water gate and start the fan drive. Since the vehicle driver sets the current temperature value through the keyboard and the preset temperature value is lower than an original fixed over-heat temperature value in the radiator system, the radiator system can be started appropriately to ensure the engine works at a safe temperature condition to prevent damage to its components.

  • Patent number: 7163193
    Abstract: A water flow-controlling device has a tube, a shaft, a block, a washer and a reciprocating assembly. The tube has a front opening, a rear opening, a side opening and a rear bracket. The openings communicate with one another. The rear bracket is mounted in the tube near the rear opening. The shaft is mounted in and is aligning with the tube and is mounted movably in the rear bracket. The block and the washer are mounted on the shaft. The block selectively obstructs the communication between the front and side openings. The reciprocating assembly connects to the shaft to move the shaft to align with the tube. The reciprocating assembly moves the shaft to extend out of the tube or the inner pressure pushes the block to prevent the block from obstructing the communication between the front and side openings.
