Embodiment
In order to further illustrate the technical solution of the utility model, 1-5 is carried out detailed to the utility model below in conjunction with the accompanying drawings
Thin explanation.
According to the heat exchanger tube protective case of the utility model implementation as in Figure 2-4.Heat exchanger tube protective case 2 is hollow cylinder knot
Structure, endoporus are available for heat exchanger tube 3 to pass through.There is boss buckle 4 at cylinder both ends, along cylinder longitudinal direction between two boss buckles 4
Distance is baffling plate thickness, and the fixation on deflection plate 1 of heat exchanger tube protective case 2 can be made to come off after installation.To protect heat exchanger tube
Sheath 2 is convenient to be installed, and a number of breach 5 is uniformly opened in the circumferencial direction of heat exchanger tube protective case 2（The preferred rectangle of breach,
Can be the other shapes such as its rectangular ellipse）.It it is 2 or 1-6 in the present embodiment.
