摘要： A refrigerant tube for a heat exchanger, comprising: a generally flat tube 10 having generally flat upper and lower walls 12/14; a plurality of reinforcing walls 16 connected between the upper and lower walls 12/14, the reinforcing walls extending along and generally parallel with a longitudinal axis A—A of the tube and being spaced apart from one another by a predetermined distance; and a plurality of communication holes 18 distributed along the length of each reinforcing wall 16, thereby defining a plurality of discrete wall portions 20 along each reinforcing wall 16, each of the discrete wall portions 20 being disposed between adjacent communication holes 18 and having an upstream edge 22 and a downstream edge 24 thereof, the communication holes 18 and discrete wall portions 20 having lengths L1 and L2, respectively, as measured along the longitudinal axis A—A, the communication holes 18 being spaced apart along each reinforcing wall 16 by a pitch P. Each communication hole 18 in each reinforcing wall is disposed between the upstream and downstream edges 22/24 of a laterally adjacent discrete wall portion 20 of each adjacent reinforcing wall, such that a wall overlap ratio Wr, defined as [P−2L1]/P, is greater than 0, and preferably 0.4≦Wr≦0.6.
