Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a constant temperature
chamber, more particularly to a self-adjusting constant temperature
chamber for testing performance characteristics of an electrical
device at different environmental temperatures.
[0003] 2. Description of Related Art
[0004] Hot property is a sort of important property for an
electrical device such as computer, server, notebook and so on. Hot
property reflects an operation state of the electrical device in
different temperature environments. When hot property of an
electrical device is tested, a simulation temperature environment
is needed. Traditionally, a constant temperature chamber is
designed for testing an electrical device placed therein. The
temperature in the constant temperature chamber can be adjusted
within a range of necessary temperatures. Consequently, the
constant temperature chamber provides a kind of simulation
temperature environment for testing the electrical device.
[0005] In fact, in a realistic running environment, temperature of
every part of the electrical device is approximately uniform.
However, if the constant temperature chamber cannot simulate a real
temperature environment, the test for hot property of the
electrical device is of no effect. For adjusting a temperature in
the constant temperature chamber, the constant temperature chamber
is equipped with a heat generation apparatus and airflow assembly.
The heat generation apparatus generates heat. The airflow assembly
drives air flowing to diffuse the heat in the constant temperature
chamber to keep all positions in the constant temperature chamber
in a constant temperature. However, in the conventional constant
temperature chamber, the airflow assembly drives the air flowing in
a single direction, which can not diffuse the heat well.
[0006] Therefore, there is room for improvement within the art to
provide a power supply system for computers which can
simultaneously save boot-up time and power.

DETAILED DESCRIPTION
[0013] 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.
[0014] Referring to FIGS. 1 to 3, a constant temperature chamber 10
in accordance with an embodiment defines a cavity 30 therein. An
airflow assembly 40 is mounted in the constant temperature chamber
10. An electronic device 50 is mounted in the cavity 30 of the
constant temperature chamber 10 to be tested.
[0015] The cavity 30 has a first side 31, a second side 32, a third
side 33, and a fourth side 34. The first and second sides 31 and 32
are oriented towards each other in a vertical direction, and the
third and fourth sides 33 and 34 are oriented towards each other in
a horizontal direction. The first side 31 defines a plurality of
first vents 311. A center portion of the second side 32 forms a
location position 325. Peripheral portion of the location portion
325 defines a plurality of second vents 312. The third side 33
defines a plurality of third vents 331 thereon. The fourth side 34
defines a plurality of fourth vents 341 thereon.
[0016] The airflow assembly 40 includes a first fan 41, a second
fan 42, a receiving frame 43, four air ducts 45, and two shield
pieces 47. The receiving frame 43 is capable of mounting the first
fan 41 and second fan 42 therein.
[0017] The first fan 41 includes a first air inlet 411 and a first
air outlet 412. The second fan 42 includes a second air inlet 421
and a second air outlet 422.
[0018] The receiving frame 43 is approximately cube shaped. The
receiving frame 43 defines a receiving room 431 capable of
receiving the first fan 41 and second fan 42 therein. Four openings
432 are defined in two opposite sides of the receiving frame 43,
and are in communication with the receiving room 431. Edge of each
opening 432 extends outwards from the receiving frame 43 to form a
flange 433 on the receiving frame 43.
[0019] Each air duct 45 is capable of being secured to the flange
433 to be mounted on the receiving frame 43. The air ducts 45 are
used to guide airflow to specific positions of the constant
temperature chamber 10.
[0020] Referring to FIGS. 1 to 5, in assembly of the airflow
assembly 40, the first and second fans 41 and 42 are placed in the
receiving room 431. The two shield pieces 47 are secured on two
sides of the receiving room 431 to mount and secure the two fans 41
and 42 in the receiving room 431. The first air inlet 411 of the
first fan 41 faces to one of the four openings 432, and the first
air outlet 412 of the first fan 41 faces towards the opposite
direction. The second air inlet 421 of the second fan 42 faces to
one of the four openings 432, and the second air outlet 422 of the
second fan 42 faces towards the opposite direction. The four air
ducts 45 are secured on the four flanges 433 of the receiving frame
43 to align with the first and second air inlets and outlets
411,412, 421, and 422 of the first and the second fans 41 and
42.
[0021] Then, the airflow assembly 40 is mounted in the constant
temperature chamber 10. One of the four air ducts 45 which is
aligned with the first air inlet 411 of the first fan 41, is
communicated with the first vents 311 of the first side 31. One of
the four air ducts 45 which is aligned with the first air outlet
412 of the first fan 41, is communicated with the second vents 321
of the second side 32. One of the four air ducts 45 which is
aligned with the second air inlet 421 of the second fan 42, is
communicated with the third vents 331 of the third side 33. One of
the four air ducts 45 which is aligned with the second air outlet
422 of the second fan 42, is communicated with the fourth vents 341
of the fourth side 34.
[0022] When the constant temperature chamber 10 is in operation,
the first and second fans 41 and 42 circulate airflow. Airflow
flows through the air ducts 45 into the cavity 30 from down to up
and from right to left simultaneously, or vice versa. In the
constant temperature chamber 10, air flows in the cavity 30 in two
different directions, so heat can be well diffused in the cavity
30.
[0023] 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 embodiments, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the present disclosure to the full extent indicated
by the broad general meaning of the terms in which the appended
claims are expressed.
