Abstract
The utility model relates to a railway signaling machine cabinet and especially to a ventilating and heat-dissipating device used for an indoor machine cabinet. The device includes but not limit to an EMC ventilating net (9), an EMC liner (8), a top plate (11), an insulation base plate (14), a guide rail (12) and a fan unit (1). The EMC ventilating net (9), the EMC liner (8), the top plate (11), the insulation base plate (14), the guide rail (12) and the fan unit (1) are connected successively from top down. The fan unit (1) is composed of four fans. Plug connectors are adopted for inner wiring. The ventilating and heat-dissipating device used for the indoor machine cabinet can be maintained conveniently and takes small space. The ventilating and heat-dissipating device used for the indoor machine cabinet has good electric isolation performance and good safety precautions.
Description
Technical field
The utility model relates to railway signal and uses rack; Particularly a kind of indoor rack is used ventilation heat abstractor; It is applicable to 19 inches racks of Europe superscript series, railway computer interlock rack, communication cabinet, TDCS rack etc., is installed in enclosure top and plays the effect of ventilation and heat.
Background technology
Present most cabinet fan directly is screwed on the rack top board; Once the operate as normal that fault such as short circuit can directly influence equipment in the cabinet appears in fan, and fan breaks down and changes difficulty, do not have replacing function fast; Do not have the electromagnetic compatibility function yet; Ventilation unit takes up room greatly, no electrical isolation effect, no safety precautions etc.
Summary of the invention
The purpose of the utility model provides a kind of easy to maintenance, and it is little to take up room, and a kind of indoor rack that electrical separation and safety precautions are good is used ventilation heat abstractor.
The technical scheme of the utility model is; Provide a kind of indoor rack to use ventilation heat abstractor, comprise EMC ventilation net, EMC liner at least, top board, insulating pad, guide rail, fan unit; EMC ventilation net, EMC liner, top board, insulating pad, guide rail, fan unit connect from top to bottom successively.
Described fan unit is made up of four fans, and back panel wiring adopts plug connector to connect.
Rocker type switch and fuse are electrically connected described four fans respectively with independently.
Between described EMC liner and EMC ventilation net and top board contact-making surface the galvanized metal face is arranged.
Between guide rail and the top board insulating pad is arranged; Between guide rail and the guide rail hold-down screw insulating base is arranged.
Fan unit is connected with guide rail through the panel hold-down screw.
L shaped guide groove is arranged on the guide rail, and fan unit clothes-hook and L shaped guide groove flexibly connect.
The utility model has the advantages that: 1, through between EMC ventilation net and top board, there being EMC liner etc. to realize the Electro Magnetic Compatibility of this device.2, through between guide rail and top board, there being insulating pad etc. to realize the electrical isolation between fan unit and the rack top board.3, the fan unit clothes-hook be connected with electrical equipment graftingization etc. Application and implementation the quick replacing function of this device.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Description of drawings

Fig. 2 is the left view of rack with ventilation heat abstractor.
Among the figure, 1, fan unit; 2, supply socket; 3, rocker type switch; 4, fuse; 5, EMC pad; 6, panel hold-down screw; 7, guide rail hold-down screw; 8, EMC liner; 9, EMC ventilation net; 10, insulating base; 11, top board; 12, guide rail; 13, fan unit clothes-hook; 14, insulating pad.
Embodiment
As depicted in figs. 1 and 2, a kind of indoor rack is used ventilation heat abstractor, comprises EMC ventilation net 9, EMC liner 8 at least; Top board 11, insulating pad 14, guide rail 12, fan unit 1, EMC ventilation net 9, EMC liner 8, top board 11, insulating pad 14, guide rail 12, fan unit 1 connect from top to bottom successively; Fan unit 1 is made up of four fans, and back panel wiring adopts plug connector to connect, and is convenient to change; Each fan is with independently rocker type switch 3 and fuse 4 are electrically connected; Receive independently rocker type switch 3 controls, do not disturb mutually, whole fan unit 1 is by supply socket 2 power supplies.
EMC ventilates has EMC liner 8 between net 9 and the top board 11, and the galvanized metal face that EMC liner 8 and EMC ventilate between net 9 and top board 11 contact-making surfaces combines, and there is EMC pad 5 at the attachment screw place, has guaranteed the Electro Magnetic Compatibility of the utility model.Between guide rail 12 and the top board 11 insulating pad 14 is arranged; Between guide rail 12 and the guide rail hold-down screw 7 insulating base 10 is arranged, thereby guarantee the electrical isolation between guide rail 12 and the top board 11.
Fan unit 1 is connected with guide rail 12 through 2 panel hold-down screws 6, pulls down 2 panel hold-down screws 6 and can take off whole fan unit 1 easily.
As shown in Figure 2, supply socket 2, rocker type switch 3 and fuse 4 are arranged on the panel, L shaped guide groove is arranged on guide rail 12, can effectively reduce device takies rack at vertical direction space.Make thin as far as possible that fan unit 1 can do.Fan unit clothes-hook 13 flexibly connects with L shaped guide groove, in L shaped guide groove, moves, and guarantees that fan unit 1 takes out action for successively moving, and moves down again, conveniently takes off replacing then.
