There are several ways that a dual fan can be wired. For example, dual thermostat switches or dual relays could be used to control each fan separately. Or a
single relay could be used to control both fans
. The supplied diagram is both the most reliable and easiest method I’ve found.
How do you wire an electric cooling fan?
Most parts stores carry toggle switches and/or push-pull switches that will handle anywhere from
30-60 amps
, so that would work. If you’re using one of those thermostatically-controlled deals (or a low amp rated manual switch) you should use a relay.
Can two fans run on one relay?
Yes,
you can control dual fans separately
. You can use dual thermostatic switches that control each fan individually for example. … Start with taking both of the positive wires from the fans and connect them to the yellow wires on each relay.
How does a car works with two electric fan in front of the radiator?
Since the cooling fan motors work in tandem with the
fan blades to pull air through the radiator
, the blades will then not be able to spin or cause any airflow to cool off the car.
Does an electric fan need a relay?
Most parts stores carry toggle switches and/or push-pull switches that will handle anywhere from
30-60 amps
, so that would work. If you’re using one of those thermostatically-controlled deals (or a low amp rated manual switch) you should use a relay.
Is an electric fan better than a clutch fan?
When compared to an electric fan,
fan clutches are quite inefficient
. … The benefits of a Thermatic Fan lay in its ability to provide constant air flow, improved fuel economy, better air-conditioning performance, cooler engine running and increased engine power.
Should radiator fan turn on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches
about 200 to 230 degrees
.
Why is an electric fan better than mechanical?
An
electric fan completely removes the mechanical load of spinning the fan from the engine
. It places an additional draw on the electrical system, but this is a more efficient means of spinning a fan, and it has a smaller impact on engine drag. … An electric fan can cycle on and off, reducing the electric load.
What is the difference between condenser fan and radiator fan?
On some vehicles, for example, only the condenser fan operates with the air conditioner, while only the radiator fan operates
based on engine temperature
. On other vehicles, both fans can be activated by either air conditioning or engine temperature.
Should both radiator fans be on?
Both fans should come on when the A/C is on
. If one or both fans fail to come on, the lack of additional cooling provided by the fan may cause poor A/C cooling performance, and it may cause the A/C compressor to overheat and fail. The engine may also run hot and overheat, too.
How do you wire an electric fan with a relay?
Most parts stores carry toggle switches and/or push-pull switches that will handle anywhere from
30-60 amps
, so that would work. If you’re using one of those thermostatically-controlled deals (or a low amp rated manual switch) you should use a relay.
What symbol would best represent an electric fan in an electric circuit?
The answer is
C
. The electric fan would be represented by the symbol.
How many amps do electric fans pull?
The majority of modern ceiling fans use less than an amp, averaging
between 0.5 and 1 amp
, depending on the model and the setting. One amp drawn by a ceiling fan is equivalent to about 120 watts. Low settings use less amperage while higher settings use more.
Do electric fans add horsepower?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a
maximum of about 5 horsepower from the engine
. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
Do electric fans have engines?
Most fans are powered by electric motors
, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air.
Can you run a clutch fan and electric fan?
You can run both but 2 won
‘t cool it any better.
