Description

Technical Field

[0001] The utility model relates to the field of finned evaporators, in particular to an obliquely inserted tube finned evaporator. Background Art

[0002] The finned evaporator is a device that achieves the purpose of enhancing heat transfer by adding fins to an ordinary base tube, thereby realizing heat exchange between gas and liquid. Its working principle is mainly that the hot fluid flows in the gaps between a series of parallel metal fins, and the cold fluid flows in the gaps between adjacent fins, transferring its heat to the fins through convection and conduction heat transfer, and realizing heat exchange through the continuous heat transfer process of the fins.

[0003] The inclined tube-fin evaporator increases the heat transfer contact area and the heat conduction efficiency by setting the inclined surface of the pipe. However, it is not easy to add fins at the bends of the pipes in the general inclined tube-fin evaporator, so the fins are generally only installed at the parallel pipes. When the cold fluid in the pipe passes through the bends, there are no fins installed. Not only is the heat conduction efficiency at the bends low, but the cold fluid in the pipe at the bends will come into contact with the external environment, causing heat loss and general heat transfer effect.

By performing heat transfer operation on the pipeline of the inclined tube body 7, the cold fluid in the inclined tube body 7 always maintains an efficient warming operation, thereby ensuring the heat exchange efficiency between the hot fluid and the cold fluid.

[0030] Furthermore, an auxiliary fin 13 is fixedly connected to the side of the fixed ring block 10 on one side, and a slide groove is provided at the bottom of the two auxiliary fins 13. The surface of the oblique tube body 7 is slidably connected to the inner wall of the slide groove, and one end of the auxiliary fin 13 away from the connecting fin 12 passes through the top of the fixed outer frame 4 and is movably plugged in, thereby further increasing the heat transfer area and improving the heat exchange efficiency.

[0032] Furthermore, a groove is provided at the top of the mounting top frame 1, and the top of the screw three 9 is movably fitted to the top of the inner wall of the groove, so that the screw three 9 can be wrapped, thereby improving the stability of the fixing ring block 10 and the connecting fin 12 during installation.

[0033] Furthermore, the connecting fins 12 are arranged in an umbrella shape, and when the hot air passes through, the hot air in the fixed ring block 10 is more concentrated, thereby achieving a better heat conduction effect.

[0034] Furthermore, the heat delivery plate 11 is U-shaped, which not only facilitates the circulation of hot air, but also allows the connection fins 12 to absorb excess heat and introduce it to the installation fins 3 and the fixed fins 5.

[0035] Through the above technical solution:

[0036] When in use, first install the fixed fin 5 in the middle of the inclined plug tube body 7, and then install the installation fin 3 on the surface of the inclined plug tube body 7 and on both sides of the fixed fin 5. At this time, the inclined plug tube body 7 with the installation fin 3 and the fixed fin 5 installed is inserted into the slot at the top of the fixed outer frame 4 through the installation fin 3 and the fixed fin 5 for fixing operation, and then the cover plate 15 is threadedly fixed to one side of the fixed outer frame 4 through the screw 26 through the inlet pipe and the outlet pipe of the inclined plug tube body 7.

At this time, the heat delivery plate 11 is plugged into the top of the installation fin 3, and then the installation top frame 1 is threadedly fixed to the top of the fixed outer frame 4 by the screw one 2. Since the bottom of the installation top frame 1 is provided with a groove, the installation top frame 1 can be wrapped with the screw three 9 when installing, which improves the stability of the fixing ring block 10 and the connecting fin 12 during installation;

[0037] When the device is performing heat transfer operation, the hot air will absorb heat when passing through the mounting fins 3, the fixed fins 5, the connecting fins 12 and the auxiliary fins 13, thereby transferring the heat to the cold fluid in the oblique tube body 7. Due to the umbrella-shaped design of the connecting fins 12, the hot air in the fixed ring block 10 is more concentrated when the hot air passes through, thereby making the heat conduction effect better. At the same time, the hot air in the fixed ring block 10 generates more heat during heat conduction, which can also be transferred to the mounting fins 3 and the fixed fins 5 through the heat delivery plate 11. The mounting fins 3 are divided by the heat delivery plate 11, which not only does not affect the circulation of the hot air, but also makes the hot air more concentrated when passing through, further improving the heat transfer efficiency.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
