Description
Technical field
The invention belongs to technical field of new energy, is related to a kind of heat-insulating fire-proofing material, particularly a kind of new energy vapour
Car feature heat-insulating fire-proofing material.
Background technology
New-energy automobile body insulation flame barrier, it is the harm to reduce radiation heat transfer surface to other parts, adjacent
The thin plate layer placed between surface, using the reflective insulation principle of heat shielding, to separate the transmission of heat, while it is also certain
Local noise isolating sound effect.
New-energy automobile heating in heating part is highly unstable to the diabatic process situation of interior of body, by environment temperature, wind
The factors such as speed, the motion state of automobile in itself have a great influence, and need to be subject to from the different motion combinations of states heat transfer theory of vehicle
Analysis.The main function of new-energy automobile heat-insulating, fire-preventing part is the transmission for reducing radiant heat flux.In vehicle idling and low speed,
It also has certain barrier hot-air directly while reducing radiant heat flux and the effect of vehicle body heat convection.Therefore, at this moment
Heat-insulating, fire-preventing part is asked to radiate as early as possible preferably.
And in high speed, its effect is essentially confined to reduce the transmission of radiant heat flux, because at this moment body bottom air
Flows faster, there is cooling effect to heat generating components, i.e., heat convection at this moment is beneficial to the radiating of bottom of car part.Such as
The design of fruit polycrystalline substance it is unreasonable, there is serious turbulent flow in air-flow, and convection transfer rate can increase rapidly, can also produce and car
The bad heat exchange of body, such case need to be avoided in design.Some vehicles body platform when running at high speed it is local compared with
Heat, now except due to engine, Tail Pipe Temperature it is higher, heat radiation is stronger, also with velocity heated gas in the bad of underbody
Flowing has certain relation.
Underbody temperature must not high to making, damaging occurs in internal equipment or passenger inside the vehicle is burned under various transport conditions；
Heat-insulating, fire-preventing part should not have excessive deformation during vehicle normal use, and such as edge tilts and fractures, ftractures；It is heat-insulated anti-
The piecemeal of fiery part should lack as far as possible, and smooth, reduction air-flow disturbance as far as possible；For the narrow and small structure being difficult to avoid that, easily drawing
Play the part of turbulent flow, it may be considered that increase radiating gate hole on heat-insulating, fire-preventing part surface to improve radiating；Heat-insulating, fire-preventing part and vehicle body
Between fixed form should ensure that while fixation is reliable, take into account assembly precision and assembling convenience.It is swollen for material heat
Swollen coefficient differs larger composite construction heat-insulating, fire-preventing part, to pay special attention to the mode for connecting, fixing；According to heat-insulated situation need
Appropriate material and structure are chosen, avoids wasting.
