1. Field of the Invention

2. Description of the Prior Art(s)
A rack server is modularly designed in order to be mounted in a cabinet, and is optimized to minimize the use of physical space. The rack server further has multiple power supply systems and multiple server systems with multiple input/output (I/O) cables. The server systems and the power supply systems are mounted in the cabinet. In the modularly designed rack server, the I/O cables extend out from a rear of the cabinet.
With further reference to
Since the rack server and the cabinet have predefined sizes, the power supply system that is mounted in the cabinet also has a predefined size. As a height of the housing 90 of the power supply system has been predefined, the power supplies 92 have to be stacked and arranged side by side in the housing 90 in order to mount as many power supplies 92 as possible on the housing 90.
Under the above-mentioned arrangement, two sides of each power supply 92 are practically enclosed. Heat generated on each power supply 92 can only be dissipated from a front end and a rear end of each power supply 92. As each power supply 92 further has a fan module 920 and the fan module 920 produces an air current flowing toward the housing 90, the housing 90 has to have sufficient heat dissipating path so the heat in the housing 90 can be dissipated. However, since the flat power input panel 91 that is mounted on the front of the housing 90 is used for mounting the terminal holders 93, if multiple heat dissipating holes are formed on the power input panel 91 to dissipate heat in the housing 90, the number of the terminal holders 93 would be reduced.
To overcome the shortcomings, the present invention provides a server power supply system to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a server power supply system. The power supply system has a housing and a front panel. The housing has a front, a rear, and multiple power supply slots. The power supply slots are disposed on the rear of the housing for mounting multiple power supplies respectively. The front panel has multiple peak portions and multiple valley portions arranged alternately to form a multi-dimensional space. Each peak portion has a first inclined wall for mounting multiple terminal holders, and has a second inclined wall for forming a heat dissipating structure.
Electric power is input into the server power supply system via the terminal holder and is transformed and transmitted to the power supplies. With the terminal holders and the heat dissipating structures disposed on the peak portions of the front panel, space of the front of the housing can be utilized efficiently and heat dissipating efficiency to the server power supply system is also improved.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The server power supply system as described has the following advantages. With the at least one front panel 30 mounted on the front 101 of the housing 10, the peak portions 31 and the valley portions 32 of the at least one front panel 30 form a multi-dimensional space. Thus, heat generated from the terminal holders 50 that are mounted on the first inclined walls 311 of the peak portions 31 can be dissipated from the heat dissipating holes 3120 of the heat dissipating structures on the second inclined walls 312 of the peak portions 31.
Moreover, with the multi-dimensional space formed in the at least one front panel 30 and the heat dissipating holes 3120 of the heat dissipating structures on the second inclined walls 312 of the peak portions 31, as the air current generated by the fan modules 21 of the power supplies 20 flows toward the front 101 of the housing 10, the air current can further flow through the heat dissipating holes 3120 to generate convection and to dissipate the heat in the housing 10. Accordingly, heat dissipating efficiency to the power supplies 20 and the housing 10 is improved.
Furthermore, since the terminal holders 50 are mounted on the first inclined walls 311 of the peak portions 31 of the at least one front panel 30, the valley portions 32 of the at least one front panel 30 provide wiring spaces for disposing the terminal holders 50. Thus, each terminal holder 50 owns an exclusive wiring space not interfered with other terminal holders 50. The at least one front panel 30 not only reconciles both arrangement of the terminal holders and need for dissipating heat, but also provides sufficient wiring spaces to the terminal holders 50.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
