Description
Technical Field
The utility model relates to a heat exchanger field, in particular to roll interior coil spring tube cooler of wing outward.
Background
At present, a heat exchange tube adopted by a cooler in the market mainly comprises a straight tube or a bent tube which is communicated with the straight tube or the bent tube. When the heat exchange device is used, because the inside of the straight pipe or the bent pipe is empty, no obstruction exists, a medium can flow away quickly after passing through the inside of the straight pipe or the bent pipe, the purpose of sufficient heat exchange between the surface of the straight pipe or the surface of the bent pipe and the outside medium cannot be realized, and resource waste is caused. On the basis of the existing structure, if the heat exchange efficiency of the heat exchange tube needs to be improved, a mode of welding the flow-resisting heat exchange fins inside the straight tube or the bent tube can be fixedly adopted, but the mode has high difficulty, complex process and higher cost in the actual production and processing process; and the heat exchange fins inside the straight pipe or the bent pipe are fixedly welded, so that the daily cleaning is troublesome.
SUMMERY OF THE UTILITY MODEL
In view of the above problem, an object of the utility model is to provide a be convenient for use and production and processing, and improve heat exchange efficiency, the outer wing internal helical spring tube cooler of rolling of still being convenient for wash.
In order to realize the above-mentioned purpose, the utility model provides a pair of roll interior coil spring tube cooler of wing outward, wherein, including the tube, be equipped with a plurality of intervals heat exchange tube side by side in the tube, be equipped with respectively at the tube both ends and be fixed in the tube sheet above that with a plurality of heat exchange tubes, equally divide on the surface of every heat exchange tube and do not encircle the screw thread fin that is equipped with, the medium mouth of pipe and the medium mouth of pipe that advances that is equipped with on the tube, and be equipped with respectively inside the every heat exchange tube and insert the coil spring core with heat exchange tube fastening connection. The spiral spring core comprises a main shaft, a thread spring which is arranged on the main shaft and is mutually wound with the main shaft, and round buckles respectively arranged at two ends of the main shaft. Therefore, the shell side of the tube shell and the tube side of the heat exchange tube can be used not only under the condition that the medium is different fluid, but also under the condition that the two fluids are the same, the heat exchange tube can be widely used for heat exchange of the media such as oil, gas and water, the heat exchange area inside and outside the heat transfer tube is increased, the use amount of raw materials is reduced, and the cost performance of the heat exchanger is greatly improved.
In some embodiments, the threaded fins are replaced with outer three-dimensional fins.
In some embodiments, the medium entering and exiting the medium inlet pipe orifice and the medium outlet pipe orifice is oil or water; the medium in the heat exchange tube is air.
In some embodiments, the heat exchange tube is fixedly connected with the inner spiral spring core by brazing.
In some embodiments, a continuous steel wire is arranged on the round button of the spiral spring core in each heat exchange tube on one side of the heat exchange tube and is connected with each round button in series.
The beneficial effects of the utility model are that have in using and production and processing, and improve heat exchange efficiency, be convenient for abluent effect in addition. Because the improved structure is that the spiral spring core is arranged in the heat exchange tube with the fins in a plugging and pulling mode, the medium resistance in the heat exchange tube can be increased, and the aim of improving the medium heat exchange is also fulfilled. In addition, the spiral spring core and the heat exchange tube can be fixedly connected or fixed by brazing; if the connection is firm, the production can be processed respectively, and the working procedures are simple; in addition, the fastening connection mode is convenient when needing to be cleaned, and the cleaning can be directly carried out after being pulled out or being soaked in liquid medicine.

Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1-5, an external fin-rolling internal spiral spring tube cooler comprises a tube shell 01, a plurality of heat exchange tubes 02 arranged side by side at intervals in the tube shell 01, tube plates 03 for fixing the heat exchange tubes 02 on the tube shell 01 and arranged at two ends of the tube shell 01 respectively, threaded fins 04 arranged on the outer surface of each heat exchange tube 02 in a surrounding manner respectively, a medium inlet tube opening 05 and a medium outlet tube opening 06 arranged on the tube shell 01, and a spiral spring core 07 inserted and tightly connected with the heat exchange tubes 02 and arranged in each heat exchange tube 02 respectively. The coil spring core 07 includes a main shaft 71, a coil spring 72 disposed on the main shaft 71 and wound around the main shaft 71, and round buttons 73 disposed on both ends of the main shaft 71. The threaded fins 04 are replaced by outer three-dimensional fins. The medium entering and exiting the medium inlet pipe orifice 05 and the medium outlet pipe orifice 06 is oil or water. The medium in the heat exchange tube 02 is air. The heat exchange tube 02 is fixedly connected with the inner spiral spring core 07 by brazing. On one side of each heat exchange tube 02, a continuous steel wire 74 connected with each round button 73 in series is arranged on the round button 73 of the spiral spring core 07 in each heat exchange tube 02.
The improved structure is that the spiral spring core 07 is installed in the heat exchange tube 02 with fins in a plugging and unplugging mode, so that the medium resistance in the heat exchange tube 02 can be increased, and the purpose of improving medium heat exchange is achieved. In addition, the spiral spring core 07 and the heat exchange tube 02 can be fixedly connected or fixed by brazing; if the connection is firm, the production can be processed respectively, and the working procedures are simple; in addition, the fastening connection mode is convenient when needing to be cleaned, and the cleaning can be directly carried out after being pulled out or being soaked in liquid medicine.
