Fig. 2 is the A-A views in Fig. 1.
Include in Fig. 1-Fig. 2：
Heat exchanger tube 1, outer wall 10, inner tube 11, water pipe joint 12, dowel 13, microchannel 14, end-fitting 2.
Specific embodiment
The invention will be further described with the following Examples.
A kind of specific embodiment of 14 tube heat exchanger of microchannel of the present invention, as Figure 1-Figure 2, described one kind is micro-
14 tube heat exchanger of passage includes the end-fitting 2 of heat exchanger tube 1 and the heat exchanger tube 1, the heat exchanger tube 1
Including outer wall 10 and inner tube 11, said inner tube 11 is water stream channel, and said inner tube 11 is extended with water pipe joint 12, the water pipe
The lateral surface of connector 12 be equipped with external screw thread, the external screw thread for mechanical processing connection screw thread, the water pipe joint 12 with
Outer loop water pipe head is threadedly coupled, and prevents from revealing, and water route is flowed by outer loop water pipe head in said inner tube 11, institute
It states inner tube 11 and is equipped with dowel 13 in the radial direction, and said inner tube 11 is divided into multiple pipelines, institute by the dowel 13
It states dowel 13 and is equipped at least two, two dowels 13 are staggered, in the present embodiment, two dowels 13
For cross or arranged in a crossed manner, set the dowel 13 that the heat convection area of water can be significantly increased so that heat exchange efficiency is high,
