Dc/Dc Electric Cooling Fan
| ITEM | DESCRIPTION |
|---|---|
| 1 | DC/DC electric cooling fan |
| 2 | Cooling air inlet |
| 3 | Wiring harness connector |
| 4 | Cooling air outlet |
The DC/DC electric cooling fan is located in the DC/DC housing. The DC/DC electric cooling fan is attached to the lower DC/DC housing with 2 bolts.
The DC/DC electric cooling fan is hardwired to the DC/DC . The DC/DC electric cooling fan has a 3-pin wiring harness connector on a fly lead. The 4-pin connector has the following electrical connections:
- Power supply from the DC/DC .
- A PWM signal from the DC/DC .
- A ground through the DC/DC .
The DC/DC controls the speed of the DC/DC electric cooling fan depending on cooling requirements. The DC/DC uses a PWM signal to control the DC/DC electric cooling fan speed.
Air Ducts
| ITEM | DESCRIPTION |
|---|---|
| A | Inlet air |
| B | Outlet air |
| 1 | Outlet air duct of the DC/DC |
| 2 | Outlet air duct from the DC/DC electric cooling fan to the DC/DC |
| 3 | DC/DC electric cooling fan |
| 4 | DC/DC |
| 5 | DC/DC housing |
The inlet air duct directs the air from the passenger compartment to the DC/DC electric cooling fan.
The outlet air duct directs the air from the DC/DC electric cooling fan to cool the DC/DC when required. After cooling the DC/DC , the air exits the DC/DC housing.
