Embodiment Construction
[0016] This embodiment provides a shell-and-tube heat exchanger using copper heat exchange tubes. Such as figure 1 As shown, the shell-and-tube heat exchanger includes a copper heat exchange tube 1 and a carbon tube plate 2, and the copper heat exchange tube 1 and the carbon tube plate 2 are expanded together. On the inner wall of the hole of the carbon tube plate 2 , there are four grooves 20 distributed at intervals along the extending direction of the centerline of the hole of the carbon tube plate 2 . The depth of the groove 20 is 0.5 mm, and the distance between two adjacent grooves is 10 mm. The distance between the outermost groove 20 on the sealing surface and the edge of the carbon tube sheet 2 is 8-10 mm.
[0017] The shell-and-tube heat exchanger provided in this embodiment breaks through the limitations of traditional heat exchangers that the design pressure of expansion tubes is less than or equal to 4.0Mpa, and can ensure strength and sealing under a desig...
