Abstract
A method and apparatus for protecting personnel required to work inside of a heat exchanger unit when the cooling air fan has been taken out service for maintenance or repair of the fan or other mechanical equipment, while hot fluid continues to flow through the heat exchanger tubes, and adjacent heat exchanger units continue to operate. An inflatable heat shield is inserted into the out of service heat exchanger unit, and inflated therein to block the convective heat generated by the hot fluid and the adjacent operating units from reaching the personnel working inside the heat exchanger unit.
