Abstract
A shell and tube heat exchanger having a shell having an inner surface that defines a heat exchange zone, a refrigerant pool zone is arranged in the heat exchange zone, and a plurality of tube bundles are arranged in the heat exchange zone above the refrigerant pool zone. The tube bundles have first and second wall members that define a tube channel, and a plurality of tubes arranged in the tube channel. Each of the first and second wall members have a first end that extends to a second end that is spaced from the refrigerant pool zone. The plurality of tube bundles is spaced one from another so as to define one or more vapor passages. A refrigerant distributor is positioned above the tube channel. The refrigerant distributor delivers a refrigerant onto the plurality or tubes toward the refrigerant pool zone.
