What do people think of this?:

no reason why not
looks alright, but i don't think it would cool as well as the usual type because of the smaller surface area

edited: i mean because of only having one row through it, there's a lot of surface area on those fins

Hi

Would work if in high airflow. But as usual i would be more worried about how quick i could warm the oil rather than how to cool it .

Cheers Matt

not very good if the air flow was from the side, probably work quite well on the bottom of a boat hull

^ think what he means is (not being any kind of expert myself) is that oil coolers probably aren't really needed most of the time
you can cool the oil, but if the if the engine's not heating it as fast as the cooler's cooling it, then its not doing any good at all

So what Matt is saying is do all the other good stuff too, like:
1. Use a good radiator (Check.)
2. Get Hot air out of the engine bay quickly (Check.)
?

No different from the old "loo bush" oil cooler you used to see on production cars.

Nothing like as effective a heat exchanger as the conventional type but much less flow restriction, should be ideal for UK climate.

that looks to be expensive and IMO not very effective, unless mounted end-on in air flow, and then depending on the length and temperature, the rear will receive hotter air.

military land rovers had such a design - a tube but with coiled wire round them instead of the extruded fins so would be ok as the air can flow through the "fins" mounted sideways to the flow.


it looks nice though.

Don't waste you money on that - there is a reason why car radiators and oil coolers (apart from the water -> oil coolers) are the way they are, just use it for making Tagliatelle.

i have this type

the best oil coolers in my opinion are the oil2water heat exchangers. theres no logical reason why the oil should be less than 100degrees. dont usually need to bother with a thermostat, so long as the exchanger is placed in the interior heater water circuit.

Don't know about ordinary piston engines, but oil-to-water was used on 84-85 rotary engines by Mazda, and quickly tossed again, for not being half as good as oil-to-air.
For my engine, I'll keep using oil-to-air coolers. I don't really know the ideal temp. for oil in a piston engine, though. But 100°C seems pretty hot?

Hi Tim

I thought You knew that i only ever use the water 2 oil coolers. There's more damage done to race engines by not having the oil up to temp before racing starts than at any other time. Water brings the oil temp up much quicker and then holds it at acceptable temps during the race. All assuming of course that the water system is in good working order. You have seen the ones i have made.



The small version of our oil/water heat exchanger. Suitable for 200bhp. Larger sizes for larger bhp applications. Available with either straight or 90 deg ends. 1/2" BSP oil fittings.

Cheers Matt

^^^ is that a home made job?

I wonder how difficult it would be to make one using domestic heating pipe and fittings?

10 mm pipe inside a larger diamter pipe- reduscers sodlers on each end to keep sealed and a couple of T pieces to allow the water in out?

anyone following this?

a faction of the cost of a Lamnova (sp?), albeit nowwhere near as good heat tansfer due to no finning but may work?

stuff the space between the tubeswith stainless steel wool or that stuff pan scoureres are made of?

Hi

There's a little bit more to them than that. But at the price it wouldent even be worth trying to home make one.

Cheers Matt

How much are we talking?
