HEAT EXCHANGER TUBES WITH FLUID COMMUNICATION CHANNELS

摘要

A tube for use in a heat exchanger comprises a first portion spaced apart from a second portion. At least one reinforcing structure having a non-circular cross-sectional shape extends between the first portion and the second portion to divide a flow of a fluid through the tube into a first flow channel in one side of the at least one reinforcing structure and a second flow channel in a second side of the at least one reinforcing structure. A fluid communication channel provides fluid communication between the first flow channel and the second flow channel. The fluid communication channel is at least one among a) formed through the at least one reinforcing structure and b) formed between two adjacent reinforcing structures.
