The front panel apparatus that is used for modular power source
Technical field
The utility model relates to a kind of front panel apparatus that is used for modular power source, belongs to power supply architecture spare technical field.
Background technology
Switching Power Supply has advantages such as high efficiency, small size, is representing the developing direction of stabilized voltage power supply.Along with continuous advancement in technology, Switching Power Supply develops to modular direction day by day.Adopt the Switching Power Supply (abbreviation modular power source) of modularized design to have short, characteristics such as reliability is high, system upgrade is easy of design cycle, it is used more and more widely.
Along with a large amount of uses of semiconductor technology, encapsulation technology and high-frequency soft switch technology, the unit power density of modular power source is more and more higher.Used a large amount of large power semiconductor devices in the particularly existing modular power source, as devices such as rectifier bridge heap, big current commutates pipe, large power triode or field effect transistor.Can produce a large amount of heats during their work,, will influence the operate as normal of modular power source, can damage modular power source when serious if can not discharge these heats in time.In order to improve the reliability of modular power source work, the heat dissipation design important step that in the modular power source design, is absolutely necessary.
In addition on the one hand, existing modular power source is paid attention to not enough to the design of the structural member that comprises front and back panels, and the profile that often covets attractive in appearance ignored the requirement of heat dissipation design.And the design of some power supply architecture spare do not meet the requirement of ergonomics yet, makes the user feel very inconvenient when operation.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model provides a kind of novel modular power source front panel apparatus.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of front panel apparatus that is used for modular power source is characterized in that comprising:
Panel frame;
Be positioned at the ventilation hole of described panel frame upside, described ventilation hole has the grid of many inclinations;
Can be rotatably set in the handle of described panel frame bottom;
The shaped boss that is complementary with described handle, the position that joins at described boss and handle is provided with groove;
Be installed on the described panel frame and be positioned at the light guide plate of described ventilation hole below.
Described light guide plate is made by translucent polymethyl methacrylate, fixes below described ventilation hole.
The angle of inclination of described grid is 45 °.
This modular power source front panel apparatus is used for switch power module is installed in the rack of power-supply system.The grid that has many inclinations on the ventilation hole of this front panel apparatus can be realized good ventilation effect; Be provided with groove in the place that is connected with handle, be user-friendly for operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the front view of this modular power source front panel apparatus;
Fig. 2 is the structural representation of the light guide plate in the front panel apparatus;
Fig. 3 is the structural representation of the handle portion in the front panel apparatus.
Embodiment
Referring to shown in Figure 1, modular power source front panel apparatus provided by the utility model comprises panel frame 1, ventilation hole 2, handle 3, boss 4 and light guide plate 6 etc.Wherein, ventilation hole 2 is positioned at the upper portion in panel frame 1 front, has many grids.Has certain angle between every grid and the panel frame 1, for example 45.45 ° grid makes the draught area maximization, helps reducing windage.As long as be appreciated that to help reducing windage, ventilation hole 2 also can be other shape, as cellular etc.
Has the snap device (not shown) that this face equipment and power module are fixed together at the back side of panel frame 1.This snap device is the conventional design that persons skilled in the art can both be grasped, and has not just given unnecessary details in detail at this.
Light guide plate 6 in the front panel apparatus is positioned at the below of ventilation hole 2.As shown in Figure 2, light guide plate 6 is made by a translucent polymethyl methacrylate, can realize even light effect under the lower prerequisite of cost.Light guide plate 6 snaps in panel frame 1 by the snap device (not shown) of both sides, covers on three indicator lights, makes the light of indicator light show through light guide plate 6 easily.
Fig. 3 is the structural representation of the handle portion in the front panel apparatus, is the cutaway view of Fig. 1 on the A-A direction.In conjunction with Fig. 1 and shown in Figure 3, handle 3 is inverted concave, is positioned at the below of light guide plate 6.The bottom of handle 3 and panel frame 1 are connected by rotating shaft, so handle 3 can be the center with the rotating shaft of its bottom, opposite face plate framework 1 is rotated, and the top that makes handle 3 is away from panel frame 1, the top that becomes open state or make handle 3 becomes closure state near panel frame 1.When handle 3 became open state, the user just can grip the handle 3 of stopping with hand, and whole modular power source is pulled out from rack.Such design can be quickly installed to modular power source in the rack or from rack and take out, and makes things convenient for the user that modular power source is safeguarded or changes.
As shown in Figure 1, boss 4 and handle 3 are arranged on the bottom of panel frame 1 matchingly.The shape of boss 4 is exceeded with the rotation of the handle 3 that might as well be in the way.The position that joins at the top and the handle 3 of boss 4 is provided with groove 5, is used to place user's hand so that grip the handle 3 of stopping reliably, thereby whole modular power source is pulled out from rack.
Above this modular power source front panel apparatus is had been described in detail.For one of ordinary skill in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model connotation it being done all will constitute to the utility model infringement of patent right, with corresponding legal responsibilities.
