Abstract: An immersion liquid cooling tank assembly includes a tank, a condenser, at least one cross-flow fan, an internal wall system, a top cover, and at least one sloping wall. The tank includes a base and at least one sidewall. The base is connected to the sidewall. The condenser is located within the tank. The condenser is adapted to transform vapor into liquid. The cross-flow fan is near the condenser. The cross-flow fan produces an airflow. The internal wall system is located adjacent to the cross-flow fan to assist in directing the airflow from the cross-flow fan. The top cover is located generally opposite to the base. The sloping wall is located between the top cover and the sidewall. The sloping wall provides a closed airflow loop for the airflow produced by the cross-flow fan.

Abstract: A single-phase immersion cooling system includes an immersion cooling tank having a component area, which is separate from a main chamber and is configured to receive a heat-generating electronic device. A coolant circulates along a flow path, in a chamber path through the main chamber and a component path through the component area. A rotating propeller is mounted within the immersion cooling tank, causing a driven flow path in the component area. The driven flow path is configured to cause contact between the coolant in the driven flow path and the heat-generating electronic device when the heat-generating electronic device is received within the component area. The coolant in the driven flow path circulates at a faster speed than the coolant in the chamber path.

Abstract: An electronic device includes a metal back cover, a metal frame, and a first, second, third, and fourth radiators. The metal frame includes a discrete part and two connection parts. The connection parts are located by two sides of the discrete part, separated from the discrete part, and connected to the metal back cover. A U-shaped slot is formed between the discrete part and the metal back cover and between the discrete part and the connection parts. The first radiator is separated from the discrete part and includes a feed end. The second, third, and fourth radiators are connected to the discrete part and the metal back cover. The third radiator is located between the first and second radiators. The first radiator is located between the third and fourth radiators. The discrete part and the first, second, third, and fourth radiators form an antenna module together.

Abstract: A dual eccentric shaft driving mechanism comprises a motor, a first eccentric shaft, and a second eccentric shaft. The first eccentric shaft has a first eccentric portion. The second eccentric shaft has a second eccentric portion connected to the first eccentric shaft. The motor is connected to the first eccentric shaft for driving the first and the second eccentric shaft to rotate. Wherein, the first and the second eccentric shaft are connected to have a same rotating direction. A phase difference between the first and the second eccentric portion is maintained at 180 degrees. Compared to the prior art, a second centrifugal force generated by the rotation of the second eccentric shaft is balanced by a first centrifugal force generated by the rotation of the first eccentric shaft in the present invention. Therefore, the vibration generated in the operation of the present invention is drastically reduced.

Abstract: A magnet array member with more than four poles is used for being mounted on a shutter of a camera module of a portable mobile communication device, adjacent to one side of a yoke iron of the shutter. The magnet array member includes a disc portion and a driving portion. The disc portion has more than four N poles and S poles, and an annular side face and opposite first end face and second end face. The driving portion protrudes from one of the first end face and the second end face of the disc portion in a vertical direction. Since the driving portion protrudes from one end face of the disc portion, the disc portion can form more than four N poles and S poles when magnetized, thereby being convenient for mass production.

Abstract: A bike multi-functional rainproof assembly comprises a foldable frame having a foldable tube; a front end of the foldable tube being installed with a joint for connecting with a quick connecting rotary seat; a box having a front end combed with a rear retaining frame; the rear retaining frame for connecting to a rear side of a bike seat; the box having a lock and a ring; releasing the ring, a box bottom can be opened; the box bottom being installed with a telescopic rod set; and the telescopic rod set including a main frame, a movable rotary seat, a quick connecting rotary seat, a telescopic frame, and a sub-telescopic frame; the sub-telescopic frame being installed with a waterproof cloth; after the interior components of the telescopic rod set is expanded and fixed, the waterproof cloth having the effect of waterproof.

Abstract: A shutter device comprises a base, two electromagnetic valves, two blades, and a cover plate. A first light hole is formed in the center of base. The electromagnetic valve comprises a magnetic core, a coil unit, and a magnetic part. The magnetic cores and coil units are on the base, being axially symmetrical at the periphery of first light hole of the base. The blades join with the corresponding magnetic parts of the electromagnetic valves, in which each of the blades may travel between first and second positions at a degree of freedom to open or shut the first light hole through which rays of light pass. The cover plate is assembled onto the base and provided with a second light hole corresponding to the first light hole. The two magnetic cores are axially symmetrical on the base and lie at the periphery of first light hole.
