Abstract
The utility model discloses a thermal protection flying parameter recorder. The thermal protection flying parameter recorder comprises a protection shell, a solid state storage unit in the protection shell and encapsulating paraffin of the solid state storage unit. Paraffin is prefabricated into arc block-shaped bodies, and the paraffin blocks (3) are inlaid in air gaps of break joints of all printed circuit board assemblies (2) to perform thermal protection on the solid state storage unit of the flying parameter recorder. The thermal protection flying parameter recorder has the advantages that with a thermal protection method that the prefabricated paraffin blocks are used for filling the air gaps of the solid state storage unit, the maintainability of the flying parameter recorder is improved, the production period can be shortened, and the influence of thermal shock on service lives of components of the internal storage unit and other parts during overall paraffin encapsulation is avoided. The thermal protection method provided by the utility model also can be applied to a storage unit composed of a printed wiring board and electronic components.
Description
Technical field
The utility model relates to a kind of instrument in order to multiple flying quality in record-setting flight process.Especially strengthen the flight data recor der of thermal protection ability.
Background technology
Flight data recor der is the device of storing flight parameter on aircraft, is commonly called as " black box ", is mounted on aircraft, for helping investigation, maintenance and the flight assessment of aircraft incident.The functions such as flight data recor der generally has anticollision, puts extruding, anti-baked wheaten cake, corrosion liquid immersion, anti-sea water immersion.The TSO-C124b flight data recording instrument system technical standard order of US Federal Aviation Administration the thermo-lag requirement of flight data recor der: it is in the flame of 1100 ℃ at least 60 minutes that the whole surf zone of flight data recor der continues to be exposed to temperature, and flight data recor der is positioned over lower 10 hours of the temperature of 260 ℃, the data of its record should not be damaged.
In order to meet the specific (special) requirements of flight data recor der, flight data recor der generally consists of exterior protection housing and internal storage unit.Existing flight data recor der adopts China Patent No. ZL201220560425.4 conventionally to internal storage unit thermal protection measure, and internal storage unit is carried out to overall perfusion paraffin mode.The weak point of overall perfusion paraffin is, maintainability is poor, safeguard more difficult, the components and parts of easy damaged storage unit during dismounting, during perfusion, when the embedding temperature of paraffin approaches the temperature of the highest permission of components and parts, temperature shock has impact to the components and parts of internal storage unit and other part life.
Summary of the invention
In order to overcome the weak point of existing flight data recor der thermal protection technology, the utility model provides a kind of maintenanceability good, can avoid thermal shock on the impact of components and parts life-span, still can keep good thermo-lag flight data recor der.
The utility model solves the technical scheme that its technical matters adopts: a kind of thermal protection flight data recor der, comprise a protective casing and be arranged on solid-state storage unit and the embedding paraffin thereof in protective casing, it is characterized in that, paraffin is made circular arc blocks in advance, paraffin mass 3 is by the spaced slot of two adjacent printed board assemblys 2, be embedded in all printed board assemblys 2 and arrange in the space of break joint, flight data recor der solid-state storage unit is applied to thermal protection.
Of the present utility model have a following beneficial effect.
The utility model utilizes paraffin to melt the feature of heat absorption, select the paraffin of specific fusing point, paraffin is made to printed board assembly in advance and arrange the required given shape of break joint, being embedded in all printed board assemblys 2 arranges in the space of break joints and carries out embedding processing, strengthen the thermal protection ability of flight data recor der, make the storage unit of flight data recor der, when it stands high temperature, can melt and absorb heat by paraffin, slow down the programming rate of internal storage unit, improve the thermo-lag ability of flight data recor der.The thermal protection method that the utility model adopts Prefabricated stone wax stone to fill space, solid-state storage unit improves the maintenanceability of flight data recor der, can shorten the production cycle, solve the impact of whole embedding paraffin thermal shock on the components and parts of internal storage unit and other part life.The utility model is also applicable to the storage unit consisting of printed wiring board and electronic devices and components.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the profile organigram of the utility model thermal protection flight data recor der.
Fig. 2 is the cross-sectional schematic of Fig. 1.
In figure: 1 storage unit, 2 printed board assemblys, 3 paraffin masses, 4 protective casings.
Embodiment
Consult Fig. 1, Fig. 2.In following examples, thermal protection flight data recor der, comprise a flight data recor der protective casing 4, be arranged on the flight data recor der storage unit 1 in protective casing, be assemblied in the printed board assembly 2 in flight data recor der storage unit 1, and the paraffin mass 3 that is filled in the shaping in flight data recor der storage unit 1 space.Paraffin mass 3 is the internal voids geomeries according to flight data recor der storage unit 1, the circular arc blocks that heating is shaped in advance, and plastic paraffin piece will be as Assembly of the parts in flight data recor der storage unit 1.Paraffin mass 3 is embedded in all printed board assemblys 2 and arranges in the space of break joint, and flight data recor der solid-state storage unit is applied to thermal protection.Paraffin mass 3 is embedded in the arrangement break joint at all printed board assemblys 2 two ends.
Claims (3)
