Abstract: A heat exchange device includes a heat exchanger and two pumps. The heat exchanger defines a heat exchange pathway, an inflow pathway communicated with the heat exchange pathway for guiding a cooling liquid to flow into the heat exchange pathway, and an outflow pathway opposite to the inflow pathway for guiding the cooling liquid to flow out from the heat exchange pathway. Each of the pumps includes a case body defining a flow-guiding chamber communicated with and disposed between the heat exchange pathway and the outflow pathway, a rotor mounted in the flow-guiding chamber, and a stator mounted to the case body for driving rotation of the rotor, facilitating flowing movement of the cooling liquid toward the outflow pathway.

Abstract: An air pressure and temperature measurement system of the present invention includes a 90-degree interleaved lattice of metal wires embedded on a frame, wherein a pressure sensor and a temperature sensor are installed at each of the areas where the metal wires are connected to the frame. All the sensor modules are connected to a MCU (microcontroller unit) mounted within the frame. When air driven by fans blows over the reticulated metal wires, the sensor modules use the heat and pressure produced therefrom to enable calculating the temperature and pressure distribution at the fan openings, and then the data is transferred to an external system through a communication interface to perform more precise management and monitoring.

Abstract: A control method for adjusting rotating speed of multiple fans according to temperature of the present invention includes a micro controller circuit board and one or more fans. The circuit board is connected with one or more fans. The rotating speed of the fans are controlled by a PWM duty cycle and the signals of rotating speed are transmitted back to an MCU. Therefore, the rotating speed is adjusted consistently and proportionally with respect to the change in temperature, allowing a computer or server casing to have optimized cooling efficiency.

Abstract: The present invention relates to a fan device with modular functionality, whereby an output end and input end of the fan are respectively provided with terminal joints. Two connector joints on the I/O module connecting wires are connected respectively to the terminal joints of the output end and the input end of the fan. Therefore, the output/input terminals are modularized by means of the separated wires to reduce the problems of wire trimming.

Abstract: The present invention relates to a fan with a relocatable frame, A connecting rod of the fan is pivoted on a pivot of a base and can rotate by 300° against the pivot. A frame of the fan is pivoted on a rotating shaft which is then pivoted on the connecting rod. The frame can rotate by 360° against the rotating shaft and the rotating shaft can also rotate by 360° on the connecting rod. In addition to being put up on a desktop by itself, the fan can also be installed inside a computer.

Abstract: The present invention discloses a multiLED fan controller apparatus, which is provided with various addressable RGB (Red-Green-Blue) LEDs. Each addressable RGB LED is built in with an IC (Integrated Circuit) control chip, which is equipped with a one-wire bus control function and can be connected in a series freely. The LED fans are only provided with windows of a single input and a single output that all the addressable RGB LEDs can be controlled. In addition, all the addressable RGB LEDs are controlled individually by a controller to result in various lighting effects through the change in output signals. The lighting can be adjusted remotely by the controller, or can be adjusted by a dedicated software program.

Abstract: The present invention is a new computer housing heat dissipating configuration provided with both a heat dissipation function and the function to hide the upper power source. The upper portion of the computer housing is also installed with one to three fans that blow toward the corresponding ventilation holes in the side panel. A fan is further installed in the rear portion of the computer housing. The aforementioned fans all expel heat outwardly from the computer system, thereby causing the lower portion of the computer housing to form negative air pressure that draws air upwards from the bottom portion, whereupon the fans expel the high temperature air flow to the outside air of the computer, thus achieving premium heat dissipation.

Abstract: The present invention discloses a tool-free fastening device for a glass side panel of computer. A glass side panel at an end of the computer is provided with a movable handle, an interior of the computer is provided with a movable plate, and the glass side panel is fixed on the computer by locking lock hooks on the movable handle into through-holes of the movable plate for positioning. When the glass side panel is to be dismantled from the computer, only the movable handle needs to be pressed to displace the movable plate, and then the glass side panel can be unlocked and release from the computer.
