Abstract
The utility model discloses a dustproof ventilation chassis which is easy for maintenance, which a shell, an inner bracket which is positioned in the shell, a circuit board, a fan circuit board, a plurality of fans, and a dustproof net board. The dustproof ventilation chassis also comprises a fan bracket and a bracket of a dustproof net. The fan bracket is fixed to one side surface of the inner bracket. The bracket of a dustproof net is fixed to the other side surface of the inner bracket. The top edges and the bottom edges of the fan bracket and the bracket of a dustproof net are respectively provided with a pair of chutes. The fan circuit board and the dustproof net board are inserted between each chute. The utility model has good dustproof, ventilation and heat dissipation effects. The utility model can realize maintenance without switching off for the fans and a dustproof net and is convenient for insertion and pull.
Description
The utility model relates to electronic communication field, relates in particular to the structure of the machine box of the multilayer circuit board plug that need prevent dust, ventilate.
In the machine box series products of existing electronic product, particularly electronic communication, usually require to increase the ventilation fan heat radiation, also wish to avoid to bring a large amount of dusts into simultaneously and enter in the machine box and damage because of circulation of air.Normally directly on the sidewall of machine box, add fan, on another sidewall, add Air Filter (or dustproof sponge), this method can solve dustproof and ventilating problem, but extremely inconvenient for the replacing or the cleaning of the maintenance of fan and Air Filter, must break the machine box and just can safeguard.And the machine box of breaking must be shut down, and this often brings certain loss to the user.
In the machine box series products of existing electronic communication, machine box for the multilayer circuit board plug, its motherboard of circuit board usually has only one deck, all devices are arranged on the motherboard, cause problems such as the motherboard device is too concentrated, fan power supply must add the cable lead-in wire in addition, this motherboard of circuit board back side device ventilation and heat is bad.
The purpose of this utility model provides a kind of dustproof ventilation blower box of being convenient to safeguard, has both had good dust-proof, ventilation, radiating effect, can realize the not power-off service of fan and anti-layer net again, convenient plug.
The purpose of this utility model is achieved by the following technical solution: a kind of dustproof ventilation blower box of being convenient to safeguard comprises shell and is positioned at inner support within the shell, wiring board, fan wiring board, plurality of fans, dustproof web plate; Described wiring board is supported in the inner support; Described fan is installed on the fan wiring board; It is characterized in that described machine box also comprises blower tray and Air Filter support; Described blower tray is fixed in a side of inner support, and the Air Filter support is fixed in another side of inner support; The top margin of described blower tray and base are provided with a pair of chute, and the fan wiring board inserts between this two chute; The top margin of described Air Filter support and base also are provided with a pair of chute, and dustproof web plate inserts between this two chute.
Aforesaid the utility model machine box, its dustproof web plate one side air intake is dustproof, and its fan one side exhausting heat extraction reaches the dustproof purpose of heat radiation.Because its fan wiring board and dustproof web plate have adopted the mounting means of plug-in, fan wiring board and dustproof web plate can freely plug, and the replacing and the cleaning of the maintenance of fan wiring board, dustproof web plate are very convenient, must not break the machine box, also must not shut down.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the internal structure schematic diagram of an exemplary embodiments of the utility model machine box;
Fig. 2 is the vertical view of machine box embodiment shown in Figure 1.
The ventilation blower box that prevents dust of the utility model as depicted in figs. 1 and 2 comprises shell 1 and is positioned at inner support 2, wiring board 3, fan wiring board 4, plurality of fans 5, dustproof web plate 6 within the shell 1; Wiring board 3 is supported in the inner support 2; Fan 5 is installed on the fan wiring board 4; This machine box also comprises blower tray 7 and Air Filter support 8; Blower tray 7 is fixed in a side of inner support 2, and Air Filter support 8 is fixed in another side of inner support 2; The top margin of blower tray 7 and base are provided with a pair of chute 9, and fan wiring board 4 inserts between two chutes 9; The top margin of Air Filter support 8 and base are provided with a pair of chute 10, and dustproof web plate 6 inserts between two chutes 10.Fan wiring board 4 and dustproof web plate 6 can freely plug in chute separately, are convenient to safeguard, change and cleaning.
Present embodiment machine box also comprises two motherboard of circuit board that be arranged in parallel 11,12, and wherein motherboard 11 is connected with the back side of inner support 2, and motherboard 12 forms a passage 14 by being connected with motherboard 11 every post 13 between motherboard 11 and the motherboard 12; One end of motherboard 12 and the end of fan wiring board 4 are adjacent to one jiao of the machine box.Connected mode every post 13 and motherboard 11,12 can be to be provided with jack every post two ends and motherboard relevant position, inserts jack with contact pin in addition both are coupled together; Or establishing screwed hole every the post two ends, and install through hole in the motherboard corresponding positions, with screw both are coupled together in addition.Two motherboards are set, but the device dispersed placement has avoided in traditional machine box the motherboard device too concentrated, is unfavorable for defectives such as plug and heat radiation on two motherboards.
In the present embodiment, be provided with the connector 15 that is connected with motherboard 12 at the end of fan wiring board 4.Fan power supply is directly introduced from motherboard, must not add the cable lead-in wire in addition, save loaded down with trivial details that cable tail connects.
In the present embodiment, a position that is positioned at the end of fan wiring board 4 over against passage 14 in the fan 5 makes that all components and parts obtain good heat radiating between two motherboard of circuit board, has solved in traditional machine box problems such as motherboard of circuit board back side device ventilation and heat is bad.
The technical solution of the utility model be particularly suitable in the machine box wiring board intensive, again good ventilation heat radiation and dustproof situation arranged.
