Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to heat dissipating
assemblies, and particularly to a heat dissipating assembly with a
heat exchanger.
[0003] 2. Description of Related Art
[0004] Electronic devices generate heat during operation.
Electronic components in electronic devices may overheat and become
damaged if the heat is not dissipated quickly. Fans and heat
exchangers are used to draw heat away from the electronic
components. Generally, a heat exchanger includes a base adhered to
an electronic component (such as CPU) and a plurality of fins
extending from the base. The plurality of fins are perpendicularly
formed from the base which may increase cost.

DETAILED DESCRIPTION
[0011] The disclosure is illustrated by way of example and not by
way of limitation in the figures of the accompanying drawings in
which like references indicate similar elements. It should be noted
that references to "an" or "one" embodiment in this disclosure are
not necessarily to the same embodiment, and such references mean at
least one.
[0012] FIGS. 1 and 2 show a heat dissipating assembly in accordance
with an embodiment. The heat dissipating assembly includes two
seats 10, a base 20, a heat exchanger 30, and two pipes 50.
[0013] The two seats 10 are secured to a motherboard (not shown).
Each of the two seats 10 includes a supporting portion 11 and two
securing tabs 13, extending from two opposite ends of the
supporting portion 11. The supporting portion 11 defines two
positioning holes 111 corresponding to the base 20. Four securing
members 15 are located on each securing tab 13, to secure the two
seats 10 to the motherboard.
[0014] The base 20 includes a board 21. Three elongated latching
posts 23 protruding from an upper surface of the board 21. The
three latching posts 23 are parallel to each other, to engage with
the heat exchanger 30. Each of the three latching posts 23 has a
first extending direction, and each of the first extending
directions are parallel to each other. Each of the three latching
posts 23 includes a neck portion 231 and a head portion 233,
connected to the neck portion 231. A size of the head portion 233
is greater than a size of the neck portion 231. The board 21
defines four installation holes 211 corresponding to the two
positioning holes of each of the two seats 10. Two receiving slots
25 are defined in the board 21, for receiving the two pipes 50. The
two receiving slots 25 are positioned in a lower portion of the
board 21 and parallel to each other.
[0015] Referring to FIGS. 4-5, the heat exchanger 30 includes a
first fin 31 and a plurality of parallel second fins 33. Each of
the first fins 31 and the second fins 33 includes a fin body 311, a
first flange 313, and a second flange 314. The first flange 313 and
the second flange 314 extend from two opposite edges of the fin
body 311. The first flange 313 and the second flange 314 are
substantially parallel to each other and perpendicular to the fin
body 311. The fin body 311 defines three latching slots 315
extending to the first flange 313, corresponding to the three
latching posts 23. Each of the latching slots 315 includes a narrow
portion 3151 and a wide portion 3153, in communication with the
narrow portion 3151. A size of the wide portion 3153 is greater
than a size of the narrow portion 3151, but it is smaller than the
size of the head portion 233. A touching piece 316 (shown in FIG.
5), surrounding each latching slot 315, is located on the fin body
311. The touching piece 316 connects to the first flange 313. Each
of the first flange 313 and the second flange 314 defines two
cutouts 3131 extending to the fin body 311. Two engaging portions
331 are located on each of the first flange 313 and the second
flange 314 of each second fin 33. Each engaging portion 331 is
positioned in front of each cutout 3131. In one embodiment, each
engaging portion 331 is made of plastic.
[0016] Each of the two pipes 50 includes a heat conducting portion
51, a heat dissipating portion 53, and a connecting portion 55,
connecting the heat conducting portion 51 with the heat dissipating
portion 53. The heat dissipating portion 53 is inserted into the
heat exchanger 30, and the heat conducting portion 51 is received
in each receiving slot 25.
[0017] FIGS. 1 and 3 show that in assembly, each engaging portion
331 of one of the second fins 33 is engaged into each cutout 3131
of the first fin 31, to secure the one of the second fins 33 to the
first fin 31. The other of the second fins 33 are connected one by
one using the same way. The heat exchanger 30 is thereby assembled.
The first fin 31 and the plurality of second fins 33 cooperatively
define three elongated latching slots 315 corresponding to the
three latching post 23. Each of the three latching slots 315 has a
second extending direction, and the second extending directions are
parallel to each other and parallel to the first extending
direction.
[0018] The base 20 is secured to the two seats 10 via four locking
members 40. The heat exchanger 30 is moved towards the base 20.
Each head portion 233 of the three latching posts 23 is inserted
into each narrow portion 3151 to deform the fin body 311, until the
head portion 233 is engaged into the wide portion 3153. The fin
body 311 resiliently rebounds to engage the touching piece 316 with
each neck portion 231, to secure the heat exchanger 30 to the base
20. The touching piece 316 abuts the corresponding latching post 23
in a direction substantially perpendicular to the extending
direction, to dissipating heat from the base 20. The first flange
313 of the heat exchanger 30 abuts the board 21 of the base 20.
[0019] In disassembly, the heat exchanger 30 is pulled away from
the base 20. The touching piece 316 is resiliently deformable to
disengage the head portion 233 from the latching slot 315, to
detach the heat exchanger 30.
[0020] It is to be understood, however, that even though numerous
characteristics and advantages of the embodiments have been set
forth in the foregoing description, together with details of the
structure and function of the present disclosure, the disclosure is
illustrative only, and changes may be made in detail, especially in
the matters of shape, size, and arrangement of parts within the
principles of the embodiments to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
