Embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
The operation principle of this multichannel composite radiating sealed cabinet is: based on the composite channel radiating mode of inside and outside twin fin structure, and the cooling means that adopts conduction to combine with forced air cooling.The cabinet biside plate is double-decker, and the internal module heat relies on air-cooled the conduction with sidewall of internal layer blower fan to bring the ground floor passage into, and heat exchanger plates is completed heat exchange in two sides, then heat is taken away from air channel, the outside by outer blower fan.
This cabinet is mainly by chassis frame, side heat exchanger plates, interior demarcation strip, rear end heat exchanger plates, and outer shrouding, rear shrouding, front panel and upper and lower cover plates sealing form.When higher to EMC Requirements, can install barricade additional in cabinet bottom, be used for reducing motherboard and cable radiation to the impact of shielding properties.
With reference to above-mentioned accompanying drawing, chassis frame 1 is the installation carrier of cabinet inner module plug-in unit, motherboard and other components and parts, adopt the magnesium alloy cast shaping thin wall, chassis frame 1 is connected with the General Aviation frame with front suspension member 3 by rear pin shaft 2, realizes quick-detachment and the installation of cabinet and aviation frame.External connector and the handle of cabinet is installed on front panel 4, and front panel 4 is detachable with chassis frame 1.Demarcation strip 5 plays the effect of isolation cabinet inside forceful electric power and light current, and the forceful electric power analog module plugin card installation in cabinet is at regional I, and the light current digital circuit is arranged in regional II, and regional III is the air channel of hollow, is connected with regional IV.Side heat exchanger plates 7 is arranged on chassis frame 1, the inside and outside all soldering radiating fins of interior demarcation strip 9, by 1479 and upper cover plate 13 lower covers 14 complete the airtight of inner chamber body, cycling through inner blower 8 in whole cabinet completes, inner blower mounting panel 6 is the installation carrier of inner blower 8, forms simultaneously the negative pressure cavity of its work.
Inner chamber body is divided into independently two zones: forceful electric power zone I and light current zone II, because both are independently each other, can realize airtight and electromagnetic sealing.Internal heat generation less module heat in forceful electric power zone is delivered to the two side of interior circulation according to conventional seals case radiation principle by locker, the two side is designed with radiating fin 15, completes heat radiation by interior circulation.Be designed with hollow air channel III in inner chamber body, the forceful electric power zone is passed in this air channel, completes the interior circulation of the cooling blast in light current zone.
The digital signal integrated circuit board plug-in unit 16 in light current zone is installed together with cold drawing 17 itself.The heat of printed board device is connected with cold drawing 17 by flexible chill bar 18.Cold drawing 17 outer surfaces are processed with radiating fin.The cool stream of interior circulation is by fin, thus the heater members in cooling printed board.
Exocoel enclosed area V is by chassis frame 1, outer shrouding 10 and 11 realizations of rear shrouding, and exocoel is connected with atmosphere.Outer circulation is by blower fan 12 realizations, and blower fan 12 is arranged on rear shrouding 11.Extraneous cooling blast is completed the heat exchange of interior outer chamber on side heat exchanger plates 7 and interior demarcation strip 9.
The inside and outside all brazing fins 24 of interior demarcation strip 9, the inside and outside all soldering radiating fins 19 of side heat exchanger plates 7, when if the requiring of higher heat exchange efficiency arranged, usually at 7 or 9 interior pre-buried microchannel thermotubes 20, thereby complete the another one end face that heat transmits rapidly with minimum thermal resistance from an one end face.This side heat exchanger can connect and the form that is coated with conductive seal glue is connected with chassis frame 1 by friction welding (FW) or screw in compression sealing cord.
Forms the taper air channel by interior minute shrouding 9 and rear shrouding 11 and play the effect that increases blast and reduction windage.
Shield gasket plate 22 disturbs each other for fear of the printed board plug-in unit in the light current zone and designs.Generally, the printed board plug-in unit in the light current zone is the shielding cassette module, and this generic module is generally other integrated circuit boards clock signal is provided, and is very strict to the requirement of electromagnetic shielding.So, be provided with shield gasket plate 22 below caud cage position on chassis frame 1.Motherboard 23 is arranged on the neutral gear place on shield gasket plate 22, because the connector 21 of choosing is metal shell, the signal of high frequency between each module connection is simultaneously completed by the radio frequency connector that is arranged on barricade, has so thoroughly realized electromagnetic isolation each other between each module.The following dummy section of motherboard 23 is for reserving the coaxial cable cabling zone between each module.
This cabinet combines conduction, two kinds of heat dissipating methods of convection current, complete the requirement of high-power heat-dissipation in cabinet by inside and outside two circulating fans, this cabinet has solved traditional ATR conduction cooling aviation cabinet intrinsic larger bottleneck of thermal resistance of heat loss through conduction when the processing high power module is locked.When adopting this cabinet, printed board module itself need not adopt cold drawing and the pre-buried copper heat pipe of the heavier copper material of weight, and the weight of single plug-in unit like this alleviates greatly, possesses the lightweight advantage of air equipment requirement.The external mounting interface of this cabinet is identical with traditional ATR cabinet, possesses general and interchangeability.
Because interior outer chamber is isolated, and inner chamber body is airtight.So the components and parts in cabinet and the good environmental adaptability of printed board possess the advantages such as corrosion-resistant, anti-dust and waterproof.Chassis frame adopts cast magnesium alloy and differential arc oxidation, possess lightweight, the advantage such as protective is good.This multichannel composite radiating sealing aviation cabinet adopts on a plurality of products in institute, under the prerequisite of sealing structure design, has completed the heat radiation requirement of high-power high density electronic equipment.
