1. Field of the Invention
The present invention relates to a server cabinet, and more particularly to a server cabinet structure to and from which a tray can be loaded and unloaded quickly.
2. Related Art
With the development of science and technology, a computer device is expected to start and run various programs within a shortest period, so as to meet speed requirements of data processing from customers. Development objects of increasing processing speed and performing multiplex operation are achieved by increasing chip precision in the industry, so that server architecture consisting of multiple circuit boards and electronic components thereof is developed.
When multiple main boards are to be installed in an existing server rack, the multiple main boards are placed on provided trays. Additionally, the server rack is divided into multiple rooms, so that all of the trays loaded with the main boards are arranged in the rack at intervals. In addition, with multiple sets of slide rail structures inside the rack, the trays are inserted in the rack.
In order that the trays can be easily placed in the server firmly, multiple slide rail brackets and multiple slide rails matching each other are mounted on the rack of the server, so as to fix and retain the trays in the server rack. Specifically, each slide rail bracket has two shoulder portions and a mounting portion, and the slide rail bracket is fixed on the server rack by screwing screws into screw holes in the shoulder portions. Each slide rail includes a pair of outer slide rails mounted on the slide rail bracket and a pair of inner slide rails mounted on the server, and the server slides into the outer slide rails through the inner slide rails.
After the tray is pushed to a predetermined position in the server rack, the server and a fixing plate are combined to each other, and a thumb screw passes through the tray and the fixing plate and is screwed into a corresponding screw hole of the rack, so as to fix the tray inside the rack, thus ensuring an electrical connection between a main board in the tray and a power system of the server rack (connection in the form of electrical connectors).
High reliability and high extensibility are the most required for the main boards of the conventional server, and the main reason is that each main board has a hot swapping function, the main board can be directly electrically connected to an external electrical connection port through an electrical connector, and the main board of the server is required to be plugged in and pulled out frequently. Therefore, the fixation achieved by screwing the screw into the screw hole makes it inconvenient to plug in and pull out the main board of the server, and also leads to problems that the alignment of the screws is not easy, the screws are easily lost, and the thumb screw is expensive.
In addition, in order that the trays can be placed firmly in the rack and can slide relative to the rack, the conventional server rack must be mounted with multiple sets of slide rail brackets and slide rails for directly placing the trays thereon. Thus, the slide rail brackets and slide rails occupy too much room inside the server rack, which limits the usable room in the server rack. Therefore, the number of circuit boards that can be loaded in a single server rack is also limited, and installation of the maximum number of circuit boards cannot be achieved, so that the operation performance of the server cabinet cannot be improved.
In view of the above problems, the present invention is a server cabinet structure, so as to solve the problems in the prior art that the fixation of the trays to the server rack by screws is rather inconvenient, making it inconvenient to plug in and pull out the main board of the server, and that the server rack cannot be loaded with the maximum number of circuit boards, because the slide rail brackets and slide rails occupy too much usable room in the server rack.
The server cabinet structure of the present invention comprises a rack, at least one tray and at least one fixing component. The rack has two opposite frame bars and at least two guide rails. Each of the frame bars is opened with a plurality of assembly holes. The two guide rails are respectively disposed on the frame bars, and the guide rails are arranged corresponding to each other. The tray is disposed on the two guide rails, and is capable of sliding into the rack through the guide rails. The tray has at least one stop plate and two recessed portions. The stop plate has at least one combining hole. The two recessed portions are respectively corresponding to the two guide rails. When the tray is located in the rack, the two guide rails are respectively accommodated in the two recessed portions, the stop plate presses against one of the frame bars, and the combining hole of the stop plate is corresponding to one of the assembly holes of the frame bar. The fixing component passes through the combining hole and at least one of the assembly holes, and is inserted into at least one of the frame bars, so as to limit and keep the tray inside the rack.
Beneficial effects of the present invention are as follows. The fixing component is fixed in the frame bar by insertion, so that the tray can be fixedly disposed into the rack or removed from the rack quickly and conveniently, which not only greatly simplifies the procedures for loading and unloading the tray, but also reduces the time required for the loading and unloading operations.
Additionally, the guide rails of the rack are completely accommodated in the recessed portions of the tray, and do not occupy any other usable room inside the rack, so that the rack can be loaded with the maximum number of circuit boards, and a single server cabinet can achieve the highest operation performance.
These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.
These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.
The accompanying drawings illustrate one or more embodiments of the invention and, together with the written description, serve to explain the principles of the invention. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment, and wherein:
The guide rails 112 of the present invention are disposed on the frame bars 111 respectively, and protrude inwards from the frame bars 111 respectively. The guide rails 112 on the two frame bars 111 are arranged symmetrically. One of the side surfaces of the rack 110 is further disposed with at least one assembling frame 115, the assembling frame 115 is located in the accommodation room of the rack 110, and one side of the rack 110 opposite to the assembling frame 115 is opened with an air outlet 116.
The fan module 150 is mounted inside the assembling frame 115 of the rack 110 laterally, so that the fan module 150 is held on the rack 110 and remains the mounting position unchanged, and thus the fan module 150 can steadily blow an airflow towards the air outlet 116.
It should be noted that, the number of the guide rails 112 of the rack 110 is multiple, and the multiple guide rails 112 on the frame bars 111 are disposed at intervals, so that an in-between accommodation room is formed between two adjacent guide rails 112. The height of the in-between accommodation room matches the height of the tray 120 exactly. Additionally, in the present invention, the number of the fan modules 150 and the number of the assembling frames 115 of the rack 110 are also multiple. The numbers of the components of the above server cabinet 100 are corresponding to each other, and those skilled in the art may adjust the numbers according to the practical requirements, which is not limited to the embodiments disclosed in the present invention.
As shown in
Specifically, the tray 120 has two opposite side walls 121, and the side walls 121 are further opened with through holes 122. The tray 120 further has two stop plates 123 disposed on the two side walls 121 of the tray 120 respectively. The stop plates 123 are substantially perpendicular to the side walls 121. The stop plates 123 function as the peripheral architecture of the tray 120.
In this embodiment, the stop plates 123 and the tray 120 may be integrally formed, or the stop plates 123 may be additionally mounted on the tray 120, and the present invention is not limited thereto. Additionally, the number of the stop plates 123 in the present invention is two, and the stop plates 123 are symmetrically disposed on the tray 120, so as to achieve a force balance. However, those skilled in the art may simply achieve the retention affect by only disposing a single stop plate 123 on one of the side walls 121 of the tray 120, which is not limited to this embodiment.
The circuit board 130 has two opposite long side edges 131 and two opposite short side edges 132, thus forming a rectangular board structure. When the circuit board 130 is loaded on the tray 120, the long side edges 131 of the circuit board 130 are parallel to the side walls 121 of the tray 120, and the short side edges 132 of the circuit board 130 are parallel to the stop plates 123 of the tray 120.
As shown in
When the tray 120 slides into the rack 110, the tray 120 is located in an in-between accommodation room formed by two adjacent guide rails 112, and relative positions of the stop plates 123 overlap relative positions of the frame bars 111, so that the stop plates 123 press against the two frame bars 111. At this time, the combining hole 124 of the stop plate 123 is aligned to the assembly hole 113 on the frame bar 111, and the guide rails 112 are completely submerged in the recessed portions 125 of the tray 120, so that the bottom of the tray 120 and the bottom of the guide rails 112 are in the same plane, thus greatly reducing the usable room in the rack 110 occupied by the guide rails 112, and achieving the most efficient utilization of the inner room of the rack 110.
The fixing component 140, such as a pin, passes through the combining hole 124 of the stop plate 123 and the assembly hole 113 on the frame bar 111, and is inserted into the frame bar 111, so that the tray 120 is limited by the fixing component 140 and thus kept in the rack 110. In this embodiment, the fixing component 140 is a pin, but those skilled in the art may also select any fixing component other than those for screw fixation, which is not limited to the implementation of this embodiment.
Referring to
The server cabinet 100 of the present invention further comprises at least one radiator 160, mounted on the side surface of the rack 110 having the fan module 150, and located outside the rack 110. In the present invention, the radiator 160 and the fan module 150 are disposed close to each other, and the radiator 160 is located at an air inlet end of the fan module 150, so that the radiator 160 can effectively lower the temperature of the air at the air inlet end of the fan module 150, thus preventing the temperature of the airflow blown into the rack 110 from being too high. The number of the radiator 160 of the present invention may be multiple, so as to provide an optimal heat dissipation effect to the server cabinet 100.
In the present invention, the fixing component is fixed in the frame bar by insertion, so that the tray can be fixedly disposed into the rack or removed from the rack quickly and conveniently, and compared with the prior art, the present invention does not need to use screws for screw fixation as the fixing components, which not only greatly simplifies the procedures for loading and unloading the tray, but also reduces the time required for the loading and unloading operation.
Additionally, the guide rails of the rack are completely accommodated in the recessed portions of the tray, and the guide rails do not protrude from the tray, but instead, are in the same plane as the tray. Since the guide rails do not occupy any other usable room inside the rack, the most efficient utilization of the usable room of the rack can be achieved, the rack can be loaded with the maximum number of circuit boards, and a single server cabinet can achieve the highest operation performance.
