Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a coiled tube heat exchanger. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers heat between two or more media at different temperatures. Compared with ordinary shell-and-tube heat exchangers, spiral wound tube heat exchangers have incomparable advantages. They are applicable to a wide temperature range, can adapt to thermal shock, eliminate thermal stress by themselves, and are highly compact. A spiral wound tube heat exchanger consists of a spiral wound tube core and a shell, which allows the flow field to be fully developed without dead zones. It can meet the simultaneous heat exchange of multiple fluids in one device.

[0003] For example, the patent document with the announcement number CN220793951U discloses a coiled heat exchanger, in which an anti-collision plate is provided between the protective shell on the outside of the tank body and the tank body. The anti-collision plate effectively protects the tank body. The hot fluid flows inside the tank body through the spiral grooves of the spiral fan blades. The spiral fan blades effectively improve the heat exchange efficiency between the hot fluid and the spiral heat exchange tube in the tank. The spiral heat exchange tube increases the heat exchange area with the hot fluid in the spiral groove, effectively improving the heat exchange efficiency and the working speed.

[0004] However, during use, although the above patent is provided with an anti-collision plate to protect the tank body, due to the presence of a high-temperature fluid in the tank body, water droplets will condense and accumulate on the surface of the tank body after the heat exchange is completed. In addition, the anti-collision plate is in direct contact with the tank body for a long time without any gap between them. Therefore, the accumulated water droplets are not easy to evaporate, which will cause the tank body to rust over a long period of time. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 4 As shown, a coiled-tube heat exchanger comprises a base 1, a plurality of support columns 101 are welded to the bottom of the base 1, two sets of protection mechanisms for preventing collision are installed on the top of the base 1, a plurality of buffer mechanisms are arranged in the protection mechanisms, a heat exchange mechanism is arranged between the two sets of protection mechanisms, and a disassembly mechanism for cleaning internal dirt is installed on the top of the heat exchange mechanism.

[0026] The protection mechanism includes a sliding groove 201, which is provided at the top of the base 1, and a sliding block 202 is slidably connected in the sliding groove 201. The sliding block 202 is an L-shaped block made of aluminum alloy. A mounting plate 203 is welded on the top of the sliding block 202. A protective plate 204 is bolted to one side of the mounting plate 203. A plurality of ventilation holes 205 are provided on the protective plate 204. When collided with by external objects, the protective plate 204 will drive the mounting plate 203 to move, thereby driving the sliding block 202 to slide in the sliding groove 201. The buffer mechanism includes a mounting box 301, which is bolted to one side of the mounting plate 203. A spring 302 is provided in the mounting box 301, and a fixing plate 303 is provided on one side of the spring 302. The fixed plate 303 is slidably connected to the installation box 301. One side of the fixed plate 303 is connected to a connecting column 304 by bolts. One side of the connecting column 304 is connected to an extrusion plate 305 by screws. The extrusion plate 305 is an arc-shaped plate made of heat insulating material. The installation plate 203 moves to drive the installation box 301 to move. At this time, since the extrusion plate 305 is attached to the outer surface of the heat exchanger body 401, the movement of the connecting column 304 is hindered, and then the movement of the fixed plate 303 is hindered. At this time, the movement of the installation box 301 will squeeze the spring 302, and the spring 302 will generate a rebound force. After the collision, the spring 302 pushes the installation box 301, thereby driving the installation plate 203 to reset, and then driving the protection plate 204 to reset, in preparation for the next collision.

[0027] The heat exchange mechanism includes a heat exchanger body 401, which is connected to the base 1 by bolts, and the extrusion plate 305 is attached to the outer wall of the heat exchanger body 401. The front side of the heat exchanger body 401 near the top is threadedly connected with a first medium feed pipe 402, and the front side of the heat exchanger body 401 near the bottom is threadedly connected with a first medium discharge pipe 403, and the bottom of the heat exchanger body 401 is threadedly connected with a second medium discharge pipe 404. The first medium is input through the first medium feed pipe 402, and the second medium is input through the second medium feed pipe 504. After heat exchange treatment by the heat exchanger body 401, the first medium is output through the first medium discharge pipe 403, and the second medium is discharged through the second medium discharge pipe 404. The output is through the second medium discharge pipe 404, and the disassembly mechanism includes a fixed plate 501, the fixed plate 501 is welded to the top of the heat exchanger body 401, the top of the fixed plate 501 is connected with a connecting plate 502 by bolts, the top of the connecting plate 502 is welded with a lower hopper 503, and the top of the lower hopper 503 is threadedly connected with a second medium feed pipe 504. When it is necessary to clean the dirt inside the heat exchanger body 401, use a tool to unscrew the bolts between the fixed plate 501 and the connecting plate 502, so as to remove the connecting plate 502 from the fixed plate 501, and then remove the lower hopper 503 and the second medium feed pipe 504, and then use a tool to clean the dirt inside the heat exchanger body 401.

[0028] Working principle: When in use, the first medium is input through the first medium feed pipe 402, and the second medium is input through the second medium feed pipe 504. After the heat exchange treatment of the heat exchanger body 401, the first medium is output through the first medium discharge pipe 403, and the second medium is output through the second medium discharge pipe 404. When hit by foreign objects, the protection plate 204 will drive the installation plate 203 to move, thereby driving the sliding block 202 to slide in the sliding groove 201, and the installation plate 203 moves, driving the installation box 301 to move. At this time, since the extrusion plate 305 is attached to the outer surface of the heat exchanger body 401, the movement of the connecting column 304 is hindered, and then the movement of the fixing plate 303 is hindered. At this time, the movement of the installation box 301 will squeeze the spring 302, and the spring 302 will produce Rebound force, after the collision, the spring 302 pushes the installation box 301, thereby driving the installation plate 203 to reset, and then driving the protection plate 204 to reset, in preparation for the next collision, which can prevent foreign objects from directly colliding with the surface of the heat exchanger body 401, and prevent the heat exchanger body 401 from being damaged due to the collision of foreign objects, and can evaporate the moisture on the surface of the heat exchanger body 401, keep the outer surface of the heat exchanger body 401 dry, thereby extending the service life. When it is necessary to clean the dirt inside the heat exchanger body 401, use a tool to unscrew the bolts between the fixed plate 501 and the connecting plate 502, so as to remove the connecting plate 502 from the fixed plate 501, and then remove the lower hopper 503 and the second medium feed pipe 504, and then use a tool to clean the dirt inside the heat exchanger body 401.
