Abstract
An air cooling system including a first desiccant dryer, a second desiccant dryer connected in series in a flow path with the first desiccant dryer and a first air cooling unit connected in series in the flow path with the second desiccant dryer.
Claims17
An air cooling system, comprising:
- a first desiccant dryer;
- a second desiccant dryer connected in series in a flow path with the first desiccant dryer;
- a first air cooling unit connected in series in the flow path with the second desiccant dryer;
- and
- a device for testing an electronic component wherein air cooled and dried by the system is directed to said device.
2 more elements
A method for cooling and drying air, the method comprising the steps of:
- transmitting the air through a first desiccant dryer;
- transmitting the air through a second desiccant dryer connected in series in a flow path with the first desiccant dryer;
- and
- transmitting the air through a first air cooling unit connected in series in the flow path with the second desiccant dryer;
- wherein moisture is not intentionally added to air cooled and dried by the system.
