摘要： A flow control apparatus for use with a heat exchanger having a plurality of heat exchange tubes. The flow control apparatus comprises a housing; and the housing is divided into a first compartment for communication with a first set of heat exchanger tubes, a second compartment for communication with a second set of heat exchange tubes, an inlet compartment for connection to an external fluid source, and an outlet compartment for discharging fluid from the housing. First, second, third, and fourth ports are provided for transmitting fluid between, respectively, the first and outlet compartments, the first and inlet compartments, the second and inlet compartments, and the second and outlet compartments. The flow control apparatus further comprises a flow control gate having a normal flow position directing fluid through the second and fourth ports, and a reverse flow position directing fluid through the first and third ports.
