Description
BACKGROUND OF THE INVENTION
[0001] (1) Field of the Invention
[0002] The present invention relates to a heat dispensing unit for
removing heat from memory chips.
[0003] (2) Description of the Prior Art
[0004] A conventional heat dispensing unit 30 for memory chips is
shown in FIG. 4 and generally includes two heat conductive pads
301, two heat dispensing plates 302 and two clamps 303, wherein the
heat conductive pads 301 are attached to in sides of the two heat
dispensing plates 302 which have hooks 302a, engaging holes 302b
and engaging pieces 302c on a top thereof. When the two heat
dispensing plates 302 are combined, a space is defined therebetween
and the memory chip 2 is clamped. The engaging pieces 302c each
have a downward positioning plates 302d which are located
corresponding to the U-shaped restriction slots 304 on outsides of
the heat dispensing plates 302. A through hole 305 is located above
the restriction slot 304 and a guide slot 306 is located above the
through hole 305 so that when the two clamps 303 clamp the two heat
dispensing plates 302, the two clamps 303 are mounted onto the two
positioning plates 302d and the hoods 303a are engaged with the
through hole 305 via the guide slots 306 so that the two heat
dispensing plates 302 can clamp the memory chip 20. The heat
generated from the memory chip 2 is conducted to the heat
dispensing unit 30 and releases to air.
[0005] However, the conventional heat dispensing unit 30 includes a
complicated structure which includes hooks 303a, restriction slots
304, through holes 305 and guide slots 306. The complicated
structure makes the heat dispensing unit 30 to be expensive and
time consuming when manufacturing. Besides, the two clamps 303
clamp at the top edges of the two heat dispensing plates 302 so
that it is impossible to add extra heat dispensing plates 302 onto
the top edges.
[0006] The existed heat dispensing unit cannot efficiently dispense
the high temperature generated from the latest chips which operate
at very high speed and the low efficient heat dispensing unit
restricts the use of the high end CPU in computers.
[0007] The present invention intends to provide a heat dispensing
unit for memory chips wherein the heat dispensing plates are easily
manufactured and can be quickly connected to each other.
SUMMARY OF THE INVENTION
[0008] The present invention relates to a heat dispensing unit
which comprises two heat dispensing plates between which the chip
is clamped. Each heat dispensing plate includes two connection
plates bending from two ends thereof. The two connection plates of
one of the two heat dispensing plates have a connection piece and
the two connection plates of the other one of the two heat
dispensing plates have a connection port defined therein. Each of
the connection pieces has a contacting portion which is engaged
with an inside of the connection port corresponding thereto when
the connection pieces are connected to the connection ports.
[0009] The primary object of the present invention is to provide a
heat dispending unit for chips and the two heat dispensing plates
are easily connected to each other without using clamps.
[0010] Another object of the present invention is to provide a heat
dispending unit for chips wherein the gap between the two heat
dispensing plates is covered by two flanges on two respective tops
of the two heat dispensing plates.
[0011] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] FIG. 1 is an exploded view to show the heat dispensing unit
of the present invention;
[0013] FIG. 2 is a perspective view to show the heat dispensing
unit of the present invention;
[0014] FIG. 2A is an enlarged view to show the connection of the
connection piece and the connection ports of the heat dispensing
unit of FIG. 2;
[0015] FIG. 3 is a perspective view to show the heat dispensing
unit of the present invention, wherein the chip is clamped between
the two heat dispensing plates of the present invention, and
[0016] FIG. 4 is an exploded view to show the conventional heat
dispensing unit.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring to FIGS. 1, 2, 2A and 3, the heat dispensing unit
1 of the present invention comprises two heat dispensing plates 1
and each heat dispensing plate 1 has a heat conductive pad 15
attached to the inside thereof so that the chip 2 (FIG. 3) that is
clamped between the two heat dispensing plates 1 has sufficient
contact area for removing heat therefrom.
[0018] Each heat dispensing plate 1 has two connection plates 11
bending from two ends thereof and the two connection plates 11 of
one of the two heat dispensing plates have a connection piece 12
extending therefrom and the two connection plates 11 of the other
one of the two heat dispensing plates 1 have a connection port 13
defined therein. In this embodiment, the connection piece 12 is a
plate split from the connection plate 11 and the connection port 13
is a rectangular hole defined through the connection plate 11. Each
of the connection pieces 12 has a contacting portion 121 which is
engaged with an inside of the connection port 13 corresponding
thereto when the connection pieces 12 are connected to the
connection ports 13.
[0019] Two guide units 14 are connected to each of the two heat
dispensing plates 1 and each guide unit 14 is composed of a first
bending plate 14a which is located beside the connection piece 12
and a second bending plate 14b which is located beside the
connection port 13. The first and second bending plates 14a, 14b
are arranged such that when the two heat dispensing plates 1 are
connected to each other, the first and second bending plates 14a,
14b are overlapped to each other. The guide units 14 guide the two
heat dispensing plates 1 to be connected correctly so that the
connection pieces 12 are easily engaged with the connection ports
13. Once the connection pieces 12 are engaged with the connection
ports 13, no extra clamps are needed to hold the two heat
dispensing plates 1.
[0020] Each of the heat dispensing plates 1 further includes a
flange 16 extending from a top thereof so as to cover a gap between
the two heat dispensing plates 1. The flanges 16 avoid dust from
entering the gap between the two heat dispensing plates 1.
[0021] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
