Radiator unit
Abstract
A radiator unit includes a cooling device with a conductor, a
heat dissipated object contacting a side of the cooling device and
a fan connecting with the conductor. The heat dissipated object
contacts the hot surface of the cooling device and the cooling
device performs energy transfer to change heat to electrical
energy. Hence, current flows in a circuit formed of the conductor
to drive the fan rotating.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention:
[0002] The present invention is related to a radiator unit and
particularly to a cooling device associated with a heat generating
member for lowering temperature of the heat generating member and
supplying electric energy by way of the cooling device moving the
heat and transferring energy.
[0003] 2. Brief Description of the Related Art:
[0004] Due to various apparatus frequently producing heat during
being in operation, heat-removing device has to be utilized to
dissipate the generated heat energy. The most currently used
heat-removing device is the cooling fan. But, extremely high
temperature heat energy is incapable of being removed by the
cooling fan and it often results in shutdown or damage of the
product.
[0005] Taiwanese Patent Official Gazette No. 260325 discloses an
improved cooling and temperature control device, which provides a
fan at the top of the cooling fins and a cooling device under the
cooling fins. The cooling fins have a plurality of jut pieces at
the surfaces thereof and the jut pieces are arranged in order on
the surfaces with an end of the respective jut piece extending
outward the respective cooling fin and the contact surface of the
fan. In addition, a slot is provided at the cooling fins for being
inserted with a control circuit board. Further, a temperature
sensor 12 is disposed at an edge of a lower conductive plate 42 of
the cooling device 40 such that the temperature sensor 12 contacts
with a temperature controlled object to feed back a correct sensed
temperature so as to reach a purpose of temperature control.
[0006] However, the structure formed with the control circuit
board, the temperature sensor and the cooling device has a cooing
surface adhered with a CPU and a heat dissipation surface joined to
a fan for removing heat from the heat generating object. When the
power is off, the residue electric charges still act to the cooling
device continuously to result in the cooling surface on the cooling
device keeping absorbing heat so as to occur condensation
phenomenon and lead to short circuit. Besides, the preceding
improved cooling and temperature control device has to be supplied
power for normal working so that the prior art obviously is unable
to regenerate and reuse the energy under the condition of limited
energy and material with high cost.
SUMMARY OF THE INVENTION
[0007] A primary object of the present invention is to provide a
radiator unit in which a cooling device associated with a heat
generating member for lowering temperature of the heat generating
member and supplying electric energy by way of the cooling device
moving the heat and transferring energy for being used by other
heat dissipation device and saving resources.
[0008] Another object of the present invention is to provide a
radiator unit with which the cooling surface thereof contacts heat
generating member to prevent from short circuit due to condensation
phenomenon resulting from the cold surface of the cooling device
absorbing heat continuously.

understood with reference to the following description and
accompanying drawings, in which:
[0010] FIG. 1 is a plan view of a cooling device in a radiator

[0012] FIG. 3 is a plan view of the second embodiment of a radiator

DETAILED DESCRIPTION OF THE INVENTION
[0013] Referring to FIGS. 1, 2 and 3, the first embodiment of a
radiator unit according to the present invention includes a cooling
device 10, a cooled object 20, a fan 30 and a heat removing block
40 (see FIG. 3). The cooling device 10 basically is composed of a
plurality of P-type semiconductors 11 and a plurality of N-type
semiconductors 12 and the P-type semiconductors 11 and the N-type
semiconductors are alternately disposed to each other. Every
adjacent N-type semiconductor and the P-type semiconductor is
connected to each other by a conductor 13. A first substrate 14 and
a second substrate 15 are used to seal and pack the P-type
semiconductors 11, the N-type semiconductors 12 and the conductor
13 in a way of the conductor extending outward and exposing
outside.
[0014] The heat dissipated object 20 contacts or adheres the
cooling device 10 and, in a feasible implement, the second
substrate 15 of the cooling device 10 is adhered to the heat
dissipated object 20 to allow electrons of the N-type
semiconductors 12 acquiring energy and moving to conductive band
from the valence band as free electrons. The electrons are
transmitted with the conductor 13 to produce current, which is
reverse to moving direction of the electrons, and absorb heat at
the same time. When the electrons moves to the P-type
semiconductors 11, heat is released, that is, the heat is
transmitted from one side to another side of the cooling device to
occur Peltier effect as long as electrons pass through the N-type
semiconductors 12 and the P-type semiconductors 11. In this way,
the cooling device 10 forms temperature between a cold surface (the
first substrate 14) and a hot surface (the second substrate 15)
thereof.
[0015] Referring to FIG. 2, the heat dissipated object 20 can
contact the second substrate 15 (hot surface) and the heat
dissipated object 20 can be any heat generating object such as the
central processing unit (CPU) of a computer, power amplifier or any
other heat generating chips. The cooling device 10 performs energy
transfer to change heat to electrical energy such that current
flows in a circuit formed of the P-type semiconductors 11 and the
N-type semiconductors connecting with the conductor 13. Besides,
the conductor 13 connects with the fan 30 directly or indirectly
and the current produced by the cooling device 10 drives the fan 30
to rotate.
[0016] Referring to FIG. 3, the first substrate 14 of the cooling
device 10 is joined to the heat removing block 40 and low
temperature at the first substrate 14 is transmitted to the heat
removing block 40. The fan 30 can be mounted to heat removing block
40 and cooler air with temperature being reduced by the heat
removing block 40 is blown to carry out heat exchange with other
components or lower entire ambient temperature while the fan 30
rotates.
[0017] While the invention has been described with referencing to
preferred embodiments thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
