A fan module containing a fan is used to cool a computing device or system. The fan module is mounted within a chassis, and contains a housing, a locking body, and lever. The housing of the fan module contains a housing, a locking body, and lever. The housing of the fan module defines a hollow interior that houses the fan. The locking body is coupled to the housing and is moveable between a locked position and an unlocked position. When in the locked position, the locking body extends through a locking aperture in the floor of the chassis. When in the unlocked position, the locking body rises above the locking aperture in the floor of the chassis. Moving the lever from the first position to the second position causes the locking body to move from the locked position to the unlocked position.

A dual stage blower assembly includes a first fan configured to rotate about the rotational axis and including a first plurality blades. The first plurality of blades include a plurality of backward curved blades. The dual stage blower assembly also includes a second fan circumscribing the first fan and configured to rotate about the rotational axis. The second fan includes a second plurality of blades, wherein the second plurality of blades include one of a plurality of forward curved blades, a plurality of a radial blades, or a plurality of backward curved blades. At least one motor is coupled to the first fan and the second fan and configured to rotate the first fan and the second fan about the rotational axis.

The present disclosure describes modular fan unit systems and assemblies. A modular fan unit system assembly may include a mounting structure; and a modular fan unit system. The system may include a plurality of modular fan units, each modular fan unit having an outer housing surrounding an internal fan, the modular fan units being configured to be individually separated from the system; a filter housing unit having a plurality of filter compartments, each filter compartment configured to hold an individual air filter, wherein each modular fan unit is mounted and secured to a back side of the filter housing unit such that each modular fan unit aligns with a respective filter compartment; a plurality of louvre units, each louvre unit removably mounted to a front side of the filter housing unit such that each louvre unit aligns with a respective filter compartment; and a controller communicatively coupled with each of the modular fan units, wherein the modular fan unit system is mounted to the mounting structure.

A cooling system is described. The cooling system includes a cooling element having a central region and a perimeter. The cooling element is anchored at the central region. At least a portion of the perimeter is unpinned. The cooling element is in communication with a fluid. The cooling element is actuated to induce vibrational motion to drive the fluid toward a heat-generating structure.

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.

A fan array fan section in an air-handling system includes a plurality of fan units arranged in a fan array and positioned within an air-handling compartment. One preferred embodiment may include an array controller programmed to operate the plurality of fan units at peak efficiency. The plurality of fan units may be arranged in a true array configuration, a spaced pattern array configuration, a checker board array configuration, rows slightly offset array configuration, columns slightly offset array configuration, or a staggered array configuration.

A ventilation assembly having a main housing that can be pre-installed in a wall or ceiling aperture. A fan assembly can be inserted through the aperture and releasably mounted within the main housing. The fan assembly can be removed from the main housing and replaced without removing the main housing from the wall or ceiling. An accessory component can be releasably mounted to the fan assembly either through the aperture when the fan assembly is mounted or prior to installation of the fan assembly.

An air pump comprises a controller, a pump, a driving switch and a pressure sensor. The controller includes a central processing unit and defines an air inlet. The pump couples to the controller to inflate or discharge air from an inflatable body. The pump comprises a housing defining an inflating and a discharging port. The driving switch couples to the controller to implement switching between two or more air passage configurations. The pressure sensor couples to the central process unit to detect an internal pressure value of the inflatable body. The controller includes a wireless communication module which communicates with the central processing unit and a mobile terminal. The mobile terminal includes a terminal wireless communication module and a terminal input unit. The terminal wireless communication module communicates with the wireless communication module. The terminal input unit provides at least an inflation, a deflation, or a stop signal input.

A canopy downdraft fan assembly for being able to direct air flow like a curtain as selected. The canopy downdraft fan assembly includes a canopy assembly including support members adapted to be mounted upon a prime mover and including a canopy mounted upon the support members; and an air flow generating assembly in communication with the canopy assembly and including one or more fans.

Provided are a blower, capable of suppressing noise occurring in a stator while significantly improving blowing efficiency, and an outdoor unit using the same. The present disclosure comprises: a bell mouth part spaced apart at a predetermined distance in the radial direction with respect to an outer circumferential end of a propeller fan; and a diffuser part installed on the downstream side of the bell mouth part, and having a flow path area which is enlarged from the upstream side toward the downstream side with a larger magnification rate than the magnification rate of the flow path area in the downstream end of the bell mouth part; and a stator part having a plurality of stators, wherein the stator part is arranged within the diffuser part.
