First Claim
Patent Images
1. A method for combined preheating and cooling of a coolant for waste heat cooling of an internal combustion engine in an agricultural working vehicle, the method comprising:
- providing a heat exchanger through which coolant flows and an air delivery means to generate an air flow through the heat exchanger;
generating air flow via the air delivery means in a direction towards or away from the internal combustion engine as required;
detecting a temperature of the internal combustion engine;
producing air flow in the direction away from the internal combustion engine when a temperature value of the internal combustion engine is below a threshold value; and
reversing the air delivery means when the temperature value exceeds the threshold value.
