Why do electric radiator suck air in?

Question

I want to mount my elec fan outside the radiator and push outside air in. Any reason why not?

Answer 1

If the fan will physically fit, and turns in the proper direction (blows through the radiator) There is no reason you can't do it. I have seen several imports (Toyota, Nissan) do this due to lack of under-hood space. It's known as a "Pusher" fan. Many times, the manufacturer will use both a Pusher and Puller fan for heavy duty applications. So as long as your engine doesn't overheat, you're golden. The biggest reason most fans are "Puller" fans, is because the manufacturer can make a fan shroud that will allow the fan to pull more air at the same fan RPM, making it more efficient.

Answer 2

They do that because the fan is behind the radiator. Most of the time the fan does not run because the motion of the car is sufficient to blow air across it.

Answer 3

All -- I advise all,-- radiators have airflow coming in from the front, and blowing out by ability of the engine compartment! Air is available in from the front, is going by ability of a/c condenser )if it has a/c, - then by ability of the radiator, - then blows over the engine (and there is a few cooling content cloth even the following), - and out lower than the bottom of auto! the in straightforward words exception is a rear engine vehicle that has the radiator contained in the rear (in the back of engine)-in the route of back of motorcar! someone has positioned an after marketplace fan in (and has one with incorrect route of rotation "set" on the blades, - or replaced the electric powered cooling fan and hooked the wires up backward! that's definately no longer reliable! because as youchronic down the line, there's a "null element" the position the air merely "sits nonetheless", - this can reason engine to overheat, and may blow out a/c hoses (from overpressure)! The overheating can smash engine (in intense circumstances), and is merely no longer reliable for it in any respect (even im "minor overheating"!!) With air dealing with suitable, you get "ram air" dealing with radiator at about 30-35 mph (at that element electric powered one many times shuts off), -- I actually have pushed abode with vehicles with damaged fanbelts, and merely having wind spin waterpump fan like a windmill to pump water by ability of to keep engine cool! The battery did not value, yet i replaced into no longer left stranded (except at evening), - in which case you should discover an section to fix, or park it particularly quickly" at the same time as the hedlights commence getting dim, you recognize you're a the "end of the rope"! If the fan blows "wind backwards", it opposes airflow by ability of radiator from "ram air",- and could no longer "bypass air" till the stress on the front of motorcar overcomes the fan and forces air by ability of radiater! type of like 2 bulls "butting horns at the same time" they're expending a large type of ability and getting warm, -- yet going nowhere!

Answer 4

to pull air across the radiator fins to cool it. more effective then pushing air.

Answer 5

if you mount it out reverse the wires on the fan it will run backwards.
