BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates to a heat-dissipating pipe module, more particularly to a heat-dissipating pipe module adapted to be mounted in a cabinet for housing electronic equipment therein.
2. Description of the Related Art
Heat is generated by electronic equipment during operation. Therefore, it is necessary to dissipate heat from the electronic equipment.
Referring to
By use of a fan (not shown), air flows into the pipe members 81, and toward the electronic equipment 90 through the side openings 811 of the pipe members 81. Thus, the electronic equipment 90 can be cooled.
However, since the pipe members 81 have the same inner diameter, flow rate of the air in the pipe members 81 decreases gradually from the uppermost pipe member 81 toward the lowermost pipe member 81. As such, heat cannot be dissipated effectively from the lowermost electronic equipment 90, thereby reducing the operating efficiency of the lowermost electronic equipment 90.
SUMMARY OF THE INVENTIONTherefore, the object of the invention is to provide a heat-dissipating pipe module capable of alleviating the above drawback of the prior art.
Accordingly, a heat-dissipating pipe module of the present invention is adapted to be mounted in a cabinet that includes a box body for housing electronic equipment therein and at least one elongate pipe-mounting portion. The pipe module includes a first pipe unit including a first pipe member adapted to be disposed at the elongate pipe-mounting portion and adapted to be connected to a driving source that drives airflow. A first connecting member engages threadably an end of the first pipe member distal from the driving source. At least one side opening is in fluid communication with the first pipe member and is adapted to be directed toward the electronic equipment. A second pipe unit includes a second pipe member adapted to be disposed at the elongate pipe-mounting portion, a second connecting member, and at least one side opening in fluid communication with the second pipe member and adapted to be directed toward the electronic equipment. A major portion of the second pipe member has an inner diameter smaller than that of a major portion of the first pipe member. The second connecting member engages threadably the first connecting member and the second pipe member. The second pipe member is communicated fluidly with the first pipe member.
Other features and advantages of the invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the invention is described in greater detail with reference to the accompanying embodiments, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.
Referring to
A second pipe unit 4 includes a second pipe member 41 adapted to be disposed at the elongate pipe-mounting portion 12, a second connecting member 42, and two side openings 40 formed in the second pipe member 41 and adapted to be directed toward the electronic equipment 2. The second pipe member 41 has two opposite internally threaded ends 411. The second connecting member 42 is tubular and has an internally threaded portion 425 and an externally threaded portion 426 engaging the internally threaded portion 325 of the first connecting member 32 and the upper internally threaded end 411 of the second pipe member 41. The second pipe member 41 has an inner diameter smaller than that of the first pipe member 31. The second pipe member 41 is communicated fluidly with the first pipe member 31.
A third pipe unit 5 is adapted to be disposed at the elongate pipe-mounting portion 12. The second pipe unit 4 further includes a third connecting member 44. The third pipe unit 5 includes a third pipe member 51, a tubular fourth connecting member 52, a closure member 54, and two side openings 50 formed in the third pipe member 51 and adapted to be directed toward the electronic equipment 2. The third pipe member 51 is aligned with and adjacent to the second pipe member 41, has two opposite internally threaded ends 511, and is communicated fluidly with the second pipe member 41. The closure member 54 engages threadably and seals one of the internally threaded ends 511 of the third pipe member 51 that is distal from the second pipe member 41. The tubular fourth connecting member 52 has an externally threaded portion 526 engaging one of the internally threaded ends 511 of the third pipe member 51 proximate to the second pipe member 41. The third pipe member 51 has an inner diameter smaller than that of the second pipe member 41. The third connecting member 44 engages threadably the externally threaded portion 526 of the fourth connecting member 52 and one of the internally threaded ends 411 of the second pipe member 41 that is distal from the first pipe member 31. The second pipe member 41 is communicated fluidly with the third pipe member 51.
The driving source drives airflow into the heat-dissipating pipe module mounted in the cabinet 1. Air flows from the first, second, and third pipe units 3, 4, 5, and then is directed toward the electronic equipment 2 through the side openings 30, 40, 50. An exhaust fan module (not shown) is provided to force air out of the cabinet 1 after heat exchange, such that heat convection is also conducted to further cool the electronic equipment 2. Due to the differences among the inner diameters of the first, second, and third pipe members 31, 41, 51, the flow rate of the air in the second pipe member 41 is not slower than that of the first pipe member 31, and the flow rate of the air in the third pipe member 51 is not slower than that of the second pipe member 41. Therefore, heat exchange efficiency of the present invention is better than that of the prior art.
It should be noted that the combination of the first, second, and third pipe members 31, 41, 51 is not limited to the first preferred embodiment. The number of the first, second, and third pipe members 31, 41, 51 may be changed according to the amount of heat generated by the electronic equipment 20, such that the flow rate of the air can meet heat-dissipating requirements. For example, the second pipe member 41 and the third connecting member 44 are omitted, and the fourth connecting member 52 engages the second connecting member 42 and the third pipe member 51. Moreover, the closure member 54 may be replaced by any component that can seal one of the internally threaded ends 511 of the third pipe member 51 distal from the second pipe member 41.
