Heat dispensing unit for memory chip
Abstract
A heat dispensing unit includes two heat dispensing plates
between which the memory chip is clamped. Each heat dispensing
plate has a plurality of bending plates which split from an inside
of each of the heat dispensing plates and each bending plate has an
insertion and a hole. When connecting the two heat dispensing
plates, the first insertions on one of the two heat dispensing
plates are engaged with the first holes of the other heat
dispending plate. The heat dispensing plates have a flange on a top
thereof so as to cover the gap between the two heat dispensing

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 and having a flange for preventing
dust from entering the unit.
[0003] (2) Description of the Prior Art
[0004] A conventional heat dispensing unit 30 for memory chips is
shown in FIG. 5 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 20 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 20 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, there is a gap between
the two heat dispensing plates so that dust easily enters into the
space and is accumulated on the surface of the heat dispensing unit
and reduces the efficiency of the heat dispensing unit.
[0006] 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
[0007] The present invention relates to a heat dispensing unit
which comprises two heat dispensing plates between which the memory
chip is clamped. Each heat dispensing plate has a plurality of
bending plates which split from an inside of each of the heat
dispensing plates and each bending plate has a first insertion and
a first hole. The first insertions on one of the two heat
dispensing plates are engaged with the first holes of the other
heat dispending plate so connect the two heat dispensing
plates.
[0008] The primary object of the present invention is to provide a
heat dispending unit for memory chips and the two heat dispensing
plates are easily connected to each other and the gap between the
two heat dispensing plates are covered by two flanges on two
respective tops of the two heat dispensing plates.
[0009] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Referring to FIGS. 1, 2, 3, 3A and 4, the heat dispensing
unit 1 of the present invention comprises two heat dispensing
plates 10 and each have a heat conductive pad 15 attached to the
inside thereof. A plurality of bending plates 11 split from the
inside of each of the heat dispensing plates 10 and do not contact
the heat conductive pad 15. Each bending plate 11 has a first
insertion 111 and a first hole 112. The first insertions 111 are
formed by splitting material from the bending plates 11 and define
the first holes 112. Each heat dispensing plate 10 includes a
flange 12 being from a top thereof so as to cover a gap between the
two heat dispensing plates 10. Each of the flanges 12 includes a
second insertion 13 and a second hole 14.
[0017] When connecting the two heat dispensing plates 10 to each
other, the first insertions 111 on one of the two heat dispensing
plates 10 are engaged with the first holes 112 of the other heat
dispending plate 10, and the second insertion 13 are engaged with
the second holes 14.
[0018] A memory chip 20 is clamped between the two heat dispensing
plates 10 and in contact with the heat conductive pads 15.
[0019] The heat dispensing unit 1 includes flanges 12 which cover
the gap between the two heat dispensing plates 10 so as to prevent
dust from entering the gap and accumulating on the memory chip 20
and/or the heat dispensing pads 15. The heat dispensing unit 1 does
not have complicated structure and can be easily manufactured and
assembled. No extra clamps are needed for the heat dispensing unit
1 of the present invention and save a significant assembly time
required.
[0020] 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.
