Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to computer
hardwares and more particularly, to a wireless remote-control
cooler assembly for a motherboard.
[0003] 2. Description of the Related Art
[0004] According to conventional techniques, the cooling of a
motherboard is done by means of mounting at least one fan at a
boarder of the motherboard and/or at a location adjacent to a
specific chip set on the motherboard and then electrically
connecting each fan to the motherboard with multiple electric wires
through which the motherboard provides power supply to each fan and
controls the operation of each fan to cause air current for
carrying heat energy away from the motherboard.
[0005] In the aforesaid arrangement, the electric wires that
connect each fan to the motherboard constitute a control loop for
enabling the motherboard to control the operation of each fan.
Under the condition of being not modify the layout design of the
circuit board, the fan can only be installed at the border of the
motherboard or at a specifically assigned location. This design
does not provide flexibility to the fan installation. It enables
the air current to flow only in a limited space area of the
motherboard. Therefore, this design cannot achieve the best optimal
heat dissipation effect.
[0006] Further, when multiple fans are installed to provide
enhanced heat dissipation efficiency, the arrangement of the
complicated electric wiring greatly increases the cost. Arranging a
big number of electric wires in the same work space affects flowing
of air current and lowers the heat dissipating efficiency. In other
words, increasing the number of fans cannot effectively eliminate
the problem of poor dispersion of heat energy in the center area of
the motherboard. Further, the arrangement of a big number of
electric wires complicates the mechanics inspection or dismounting
operation, making the maintenance work difficult.
[0007] Therefore, it is desirable to provide a cooler assembly for
motherboard that eliminates the aforesaid problems.
SUMMARY OF THE INVENTION
[0008] The present invention has been accomplished in view of the
above-noted circumstances. It is therefore one objective of the

assembly for a motherboard, which can be installed on a motherboard
subject to actual heat dissipation requirement, improving the heat
dissipation effect.
[0009] It is another objective of the present invention to provide
a wireless remote-control cooler assembly for a motherboard, which
can save wiring consumption, and facilitate inspection and
dismounting operation during a maintenance work.
[0010] To achieve these objectives of the present invention, the
wireless remote-control cooler assembly adapted to be used with a
motherboard comprises a fan, a circuit unit electrically connected
with the fan and adapted to be electrically connected with the
motherboard for obtaining power supply from the motherboard, a
first signal transceiver module electrically connected with the
circuit unit, and a second signal transceiver module adapted to be
electrically connected with the motherboard. The first signal
transceiver module includes a receiver. The second signal
transceiver module comprises a transmitter for transmitting a
control signal to the receiver of the first signal transceiver
module to regulate the operation status of the fan through the
circuit unit.
[0011] By means of the aforesaid arrangement, the wireless
remote-control cooler assembly of the present invention can be
installed on the motherboard at any suitable location subject to
actual heat dissipation requirement, for example, the center area
of the motherboard. Therefore, the invention eliminates the
drawback of installation limitation of the prior art. Further, the
invention saves wiring consumption, simplifying the arrangement of
wiring, and facilitating inspection and dismounting operation
during maintenance work.

[0015] The present invention will become more fully understood from
the detailed description given herein below and the accompanying
drawings which are given by way of illustration only, and thus are
not limitative of the present invention, and wherein:
[0016] FIG. 1 is a perspective view of a wireless remote-control
cooler assembly in accordance with a preferred embodiment of the

DETAILED DESCRIPTION OF THE INVENTION
[0019] Referring to FIGS. 1-3, a wireless remote-control cooler
assembly 10 in accordance with a preferred embodiment of the
present invention is shown comprising a fan 20, a circuit unit 30,
a first signal transceiver module 40, and a second signal
transceiver module 50. As shown in FIG. 1, the wireless
remote-control module 10 is used with a motherboard 60.
[0020] The fan 20 is a conventional DC electric fan. Therefore, no
further detailed description in this regard is necessary.
[0021] The circuit unit 30 includes a printed circuit board
provided at a bottom thereof with a plug terminal 32 connectable to
a power socket 62 of the motherboard 60 for obtaining power supply
from the motherboard 60. The circuit unit 30 is coupled to the fan
20 by a mounting frame 33, and electrically connected to the fan 20
by means of a bus line 34 in a short distance for controlling
on/off status of the fan 20.
[0022] The first signal transceiver module 40 is electrically
connected to the circuit unit 30 and provided with a first
transmitter 42 and a first receiver 44. The first signal
transceiver module 40 detects the operation status of the fan 20
through the circuit unit 30 and transmits a feedback signal
carrying the information of the detected operation status of the
fans 20 out of the first transceiver module 40 through the first
transmitter 42. The feedback signal contains at least, but not
limited to, the information relating to the rotational speed of the
fan 20. According to this embodiment, the feedback is transmitted,
but not limited to, by means of infrared rays. That is, the
feedback signal can be transmitted by means of infrared rays, radio
frequency, or bluetooth technique in practice.
[0023] The second signal transceiver module 50 is adapted to be
electrically connected to and mechanically mounted on the
motherboard 60. The second signal transceiver module 50 includes a
second transmitter 52 and a second receiver 54. The second receiver
54 is adapted for receiving the feedback signal from the first
transmitter 42 and transmitting it to the motherboard 60, enabling
the motherboard 60 to monitor the rotational speed of the fan 20.
When regulating the rotational speed of the fan 20, the motherboard
60 drives the second transmitter 52 to transmit a control signal to
the first receiver 44 of the first transceiver module 40,
controlling the circuit unit 30 to regulate the rotational speed of
the fan 20. The control signal is a pulse width modulation (PWM)
signal for controlling the circuit unit 30 to regulate the
rotational speed of the fan 20, thereby changing the operation
status of the fan 20. According to this embodiment, the control
signal is transmitted, but not limited to, by means of infrared
rays. As will be however appreciated, the control signal can be
transmitted by means of infrared rays, radio frequency, or
bluetooth technique.
[0024] During the operation of the fan 20, the first signal
transceiver module 40 transmits a feedback signal to the second
signal receiver module 50 at the motherboard 60 so that the
motherboard 60 can control the operation of the fan 20 subject to
the information carried in the feedback signal. When it is
necessary to change of the rotational speed of the fan 20 in
regulating the heat dissipation performance, the motherboard 60
drives the second signal transceiver module 50 to transmit a
control signal to the first signal transceiver module 40, causing
the circuit unit 30 to regulate the rotational speed of the fan 20,
and therefore the heat dissipation efficiency is relatively
regulated.
[0025] As indicated above, the wireless remote-control cooler
assembly of the present invention can be installed on the
motherboard 60 at any location subject to actual heat dissipation
requirement, for example, the center area of the motherboard 60.
Therefore, the invention eliminates the drawback of installation
limitation of the conventional designs. Further, the invention
saves wiring consumption, simplifying the arrangement of wiring,
and facilitating inspection and dismounting operation during
maintenance work.
[0026] The invention being thus described, it will be obvious that
the same may be varied in many ways. Such variations are not to be
regarded as a departure from the spirit and scope of the invention,
and all such modifications as would be obvious to one skilled in
the art are intended to be included within the scope of the
following claims.
