e39 heat shield

[moots]

now this......is what i call a heat shield......maybe an overkill but a heat shield nontheless....friend's car....View attachment 28949

Well designed. I wonder if we could get the reference design from your friend to fabricate it?

Looks need :top:

bro moots
May i know, where is your friend got that aluminium sheet from.

The problem is, the shield really can protect the module?

 

[huskar3399]

neatly done, but like bro lim questioned does it really shield the heat. depends on materials, some metals are more conducive than resistive.

errr... I thought heat is transfer either by convection, conduction and radiation. correct me if I am wrong.

the heat shield have reduce the heat transfer via radiation just like a shade but may increase the heat via conduction.

Imagine standing in a sealed room made of zinc roof and wall and under the hot sun. (hot box)

worried the headers will melt coz too hot..no ventilation and heat accumulation..maybe just maybe...

protecting the module itself is sufficient i guess, use material something like being used in the roof - aluminium + foam

my layman thought, the amount of heat is same but the amount of heat radiating towards the ABS module is lessened because it is blocked by the heat shield. bigger portion will reflected back.

Maybe something made of insulators will help. Any suggestion of insulator materials to use as heat shield for the ABS module?

this shield was custom made and a once off thingy.after looking at my homemade shield he told his mech to do this and the result is as such.me thinks this will not do a 100% job of protecting the abs module.it is mounted via the vlv cover hold down bolts and this could lead to oil leaks and the leak(if any) will not be noticeable as it is hidden by the shield.me also thinks the best way to protect is to wrap the whole module in black 'foam like' material like one of our forummer here has done (can't remember who).

I suppose later e39 come with ABS protection heat shield. Should be able to get 1 & no need to custom make...View attachment 28975

That heatshield that is shown is modified. It does not come in that way originally.

Actually just a simple metal plate will do but need some tricky method. As what i done is, i never fully covered my ABS module. I just only use metal plate to prevent hot air direct heating the ABS module while driving the car. And it never cover front and the back of ABS module, this is because need to let cold air to flow into it.

i saw some e39 equip with this shield & same material too. Mine is similar like this... i thought is stock equipmnent

Though it may be a good ABS module heat shield, a potential problem from this design is that it traps engine heat and reduce/deflect air flow to that part of the engine.

Yes the shield is a stock item but it only shileds the sidewall towards the tyre and does not cover the ABS module.
