Abstract
Description
- 1. Technical Field
- 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.
- 2. Description of Related Art
- 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.
- 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.
- 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.
- Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an isometric view of a constant temperature chamber in accordance with one embodiment. -
FIG. 2 is similar toFIG. 1 , but viewed from another aspect. -
FIG. 3 is an exploded and isometric view of an airflow assembly of the constant temperature chamber ofFIG. 1 . -
FIG. 4 is an assembly view of the airflow assembly ofFIG. 3 . -
FIG. 5 is a sectional view taken along line V-V ofFIG. 4 . - 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.
- Referring to
FIGS. 1 to 3 , aconstant temperature chamber 10 in accordance with an embodiment defines acavity 30 therein. Anairflow assembly 40 is mounted in theconstant temperature chamber 10. Anelectronic device 50 is mounted in thecavity 30 of theconstant temperature chamber 10 to be tested. - The
cavity 30 has afirst side 31, asecond side 32, athird side 33, and afourth side 34. The first andsecond sides fourth sides first side 31 defines a plurality offirst vents 311. A center portion of thesecond side 32 forms alocation position 325. Peripheral portion of thelocation portion 325 defines a plurality of second vents 312. Thethird side 33 defines a plurality ofthird vents 331 thereon. Thefourth side 34 defines a plurality offourth vents 341 thereon. - The

first fan 41 includes afirst air inlet 411 and afirst air outlet 412. Thesecond fan 42 includes asecond air inlet 421 and asecond air outlet 422. - The
receiving frame 43 is approximately cube shaped. Thereceiving frame 43 defines areceiving room 431 capable of receiving thefirst fan 41 andsecond fan 42 therein. Fouropenings 432 are defined in two opposite sides of thereceiving frame 43, and are in communication with thereceiving room 431. Edge of eachopening 432 extends outwards from thereceiving frame 43 to form aflange 433 on thereceiving frame 43. - Each
air duct 45 is capable of being secured to theflange 433 to be mounted on thereceiving frame 43. Theair ducts 45 are used to guide airflow to specific positions of theconstant temperature chamber 10. - Referring to
FIGS. 1 to 5 , in assembly of theairflow assembly 40, the first andsecond fans receiving room 431. The twoshield pieces 47 are secured on two sides of thereceiving room 431 to mount and secure the twofans receiving room 431. Thefirst air inlet 411 of thefirst fan 41 faces to one of the fouropenings 432, and thefirst air outlet 412 of thefirst fan 41 faces towards the opposite direction. The second air inlet 421 of thesecond fan 42 faces to one of the fouropenings 432, and thesecond air outlet 422 of thesecond fan 42 faces towards the opposite direction. The fourair ducts 45 are secured on the fourflanges 433 of thereceiving frame 43 to align with the first and second air inlets andoutlets second fans - Then, the
airflow assembly 40 is mounted in theconstant temperature chamber 10. One of the fourair ducts 45 which is aligned with thefirst air inlet 411 of thefirst fan 41, is communicated with thefirst vents 311 of thefirst side 31. One of the fourair ducts 45 which is aligned with thefirst air outlet 412 of thefirst fan 41, is communicated with thesecond vents 321 of thesecond side 32. One of the fourair ducts 45 which is aligned with thesecond air inlet 421 of thesecond fan 42, is communicated with thethird vents 331 of thethird side 33. One of the fourair ducts 45 which is aligned with thesecond air outlet 422 of thesecond fan 42, is communicated with thefourth vents 341 of thefourth side 34. - When the
constant temperature chamber 10 is in operation, the first andsecond fans air ducts 45 into thecavity 30 from down to up and from right to left simultaneously, or vice versa. In theconstant temperature chamber 10, air flows in thecavity 30 in two different directions, so heat can be well diffused in thecavity 30. - 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.
