6 FAQs about [Generator cooling air path]

How does a generator cooling system work?

The cooling system requires airflow supplied by a fan, which is either mechanically driven from the front of the generator’s ICE or is electrically driven. Cooling systems are designed to provide adequate cooling for full load operation at a specified ambient air temperature typically between 40C° (104F°) and 50C° (122F°).

What are the different types of generator cooling systems?

Each generator set manufacturer offers different options for design of the cooling system. The two most common styles of cooling systems are closed loop and open loop systems. Closed loop systems incorporate cooling pump (s), cooling fan and radiator (s) located on a skid as an all in one unit.

What is the flow path of cooling air flow?

According to the streamline distribution in Fig. 13, the flowing path of cooling air flow is as follows: the fan rotates at a fixed rotating speed to form a low pressure area, which bring the fresh cooling air entered from the inlet of the inverter and flew to the fan after passing through the inverter.

How does a heat exchanger work in a generator?

The air is enclosed in the system and just keeps re-circulating in the internal parts of the generator. The hot air is cooled by using water heat exchangers. Which helps to maintain the temperature of the machine. In this method, the same air is used again and again for cooling the circuit.

What are the components of a generator cooling system?

Coolant System – Each generator application can have a different cooling system configuration. Below is a general list of components: • Coolant pump – Depending on engine size, belt or gear driven. Circulates coolant throughout cooling system. • Radiator – Can be single or twin radiator design.

How is air cooled?

Air flows through vessel and is cooled by tube and fin bundle. • Louvers – Used in canopy and mobile units to allow air to flow to the radiator from atmosphere. Control systems can allow for full open or full close. Advanced control systems can allow for louver to open as much as required for premium operation.
