Abstract
The utility model relates to an external composite corrosion-resistant pipe air cooler, which is mainly characterized in that: an air cooling pipe of the air cooler is a composite pipe comprising a basic-strength pipe and a corrosion-resistant pipe additionally arranged on the external wall thereof, both ends of the corrosion-resistant pipe and the positioned basic-strength pipe thereof are arranged in the same through hole, and an axial slotted hole corresponding to the corrosion-resistant pipe is arranged in the through hole. 2 to 4 radial and annular grooves are discontinuously arranged in the through hole of a pipe plate. The utility model adopts the composite pipe as the air cooling pipe, prolongs the service life of equipment and simultaneously not only satisfies the compressive-strength requirement of the equipment, but also satisfies the special structural requirement of the air cooling pipe through the connection of the air cooling pipe and the pipe plate.
Description
Technical field the utility model relates to a kind of shell and tube air cooler.
Background technology is present, be widely used in the shell and tube air cooler in many industries, its structure mainly is: some air cooling pipe two ends that are parallel to each other are located at respectively in the through hole of two parallel tube sheets, the outside of this tube sheet is provided with the bobbin carriage that the tube sheet through hole is covered, and this two bobbin carriage is respectively equipped with the import or export of fluid.Its weak point is: be augmentation of heat transfer efficient, often adopt the wet type air cooling of shower water, because the air cooling pipe adopts carbon steel pipe more, the synergy of dissolved oxygen and carbon dioxide under water vapour environment, make the corrosion of ordinary carbon steel air cooling pipe very serious, the service life that causes wet air cooler is well below designing requirement; As select for use and not only satisfy requirement of strength but also good corrosion resistant material is arranged, just must improve the material rate of air cooling pipe, this certainly will significantly increase the manufacturing expense of equipment.
The summary of the invention the purpose of this utility model is to provide a kind of outer composite corrosion proof pipe air cooler that less expense can solve existing air cooling pipe etching problem that only increases.The utility model mainly is to set up corrosion resistant metal material layer at the outer wall of conventional air cooling pipe, makes it to become multiple tube.The multiple tube that air cooling pipe of the present utility model is made up of basal strong pipe and corrosion resistant pipe.Wherein basal strong pipe is the air cooling pipe of prior art, so this basal strong pipe internal diameter is still same as the prior art, to keep flow constant.These some basal strong pipe two ends that are parallel to each other are located at respectively in the through hole of two parallel tube sheets, preferably be provided with the radial ringed groove in 2-4 road in this through hole discontinuously, make basal strong pipe and connecting of tube sheet satisfy the requirement of equipment compressive resistance, also be beneficial to the axial seal location of corrosion resistant pipe simultaneously.Setting up the corrosion resistant metal material layer of thin-walled at above-mentioned basal strong pipe outer wall is corrosion resistant pipe, and both constitute multiple tube.The two ends of this corrosion resistant pipe and the basal strong pipe at its place are located in the same through hole, are provided with the axial slots corresponding with corrosion resistant pipe in this through hole.
Though air cooling pipe of the present utility model is a multiple tube, the air cooler heat exchange principle is same as the prior art, and promptly conducting heat mainly is the convection heat transfer' heat-transfer by convection of air cooling tube fluid and air cooling pipe and the heat transfer of managing outer wall and atmosphere.
This has following advantage to the utility model mutually with prior art:
1, the utility model adopts multiple tube as the air cooling pipe, has prolonged the service life of equipment.
2, the utility model adopts the draw bail of new-type tube and tube plate to make the connection of air cooling tube and tube plate both satisfy the requirement of equipment compressive resistance, also satisfies the special construction requirement of air cooling pipe simultaneously.
Description of drawings:
Fig. 1 is the local main generalized section of looking of the utility model.
The specific embodiment: local main the looking in the generalized section of outer composite corrosion proof pipe air cooler shown in Figure 1, basal strong pipe 1 is the air cooling pipe of prior art, these some basal strong pipe two ends that are parallel to each other are located at respectively in the through hole of two parallel tube sheets 2, are provided with the radial ringed groove 3 in 3 roads in this through hole discontinuously.Set up thin-walled corrosion resistant pipe 4 at above-mentioned basal strong pipe outer wall, both constitute multiple tube.The basal strong pipe at these corrosion resistant pipe two ends and its place is located in the same through hole, is provided with the axial slots corresponding with corrosion resistant pipe in this through hole.
Claims (2)
1. outer composite corrosion proof pipe air cooler, the air cooling pipe two ends that it is parallel to each other are located at respectively in the through hole of two parallel tube sheets, the outside of this tube sheet is provided with bobbin carriage, this two bobbin carriage is respectively equipped with the import or export of fluid, it is characterized in that: above-mentioned air cooling pipe is by basal strong pipe and the multiple tube formed at the corrosion resistant pipe that its outer wall is set up, the basal strong pipe at above-mentioned corrosion resistant pipe two ends and its place is located in the same through hole, is provided with the axial slots corresponding with corrosion resistant pipe in this through hole.
