Referring to fig. 1, the present utility model proposes a disassembly-free heat exchanger, which is characterized in that the disassembly-free heat exchanger includes:
a central tube 100, the central tube 100 being provided with an injection port 110;
the heat exchanger comprises a heat exchanger body 200, wherein the heat exchanger body 200 is provided with a medium circulation port and a heat exchange cavity, and a central tube 100 is arranged in the heat exchange cavity;
the cleaning pipe 300 is provided with a cleaning opening, the cleaning pipe 300 is communicated with the central pipe 100, a part of the cleaning pipe 300 extends out of the heat exchanger body 200, and the cleaning opening is formed at one end of the cleaning pipe 300 extending out of the heat exchanger body 200;
the heat exchange tube 400, the heat exchange tube 400 is communicated with a part of medium circulation ports and is arranged in the heat exchange cavity.
In the technical scheme adopted in the embodiment, when the heat exchanger needs to be cleaned, the high-pressure water source is introduced into the cleaning pipe 300, enters the central pipe 100, and is sprayed into the heat exchange cavity through the spraying port 110 of the central pipe 100, so that the cleaning in the heat exchanger is realized. Of course, before the clean water is introduced, the cleaning agent can be introduced into the heat exchange cavity through the cleaning tube 300, and then the clean water is introduced for flushing, so as to achieve a better cleaning effect. Solves the technical problem of inconvenient cleaning of the current heat exchanger. In addition, in the normal heat exchange process, the cleaning port is communicated with the heat exchange cavity, so that the cleaning port is required to be plugged, and the heat exchange medium in the shell pass is prevented from flowing out through the cleaning port. Because the jet orifice 110 is formed on the central tube 100, the surface of the central tube 100 is uneven, so that a turbulent flow effect can be generated on the heat exchange medium in the shell side, and the heat exchange efficiency is improved. And through the injection port 110, the heat exchange medium in the shell pass can flow through the central tube 100, so that the heat exchange area is increased, and the heat exchange efficiency is further improved.
Further, the injection port 110 is circular.
In the technical solution adopted in this embodiment, the circular injection port 110 can form a linear injection water flow, and the impact force of the linear injection water flow is large, so that a relatively good descaling effect can be achieved.
Specifically, the injection ports 110 are uniformly distributed on the surface of the center tube 100. By uniformly distributing the injection ports 110, the coverage area of the injected water flow can be increased, and the cleaning dead angle can be reduced.
Further, referring to fig. 2 and 3, the injection ports 110 are formed in a groove shape, the groove-shaped injection ports 110 extend along the circumferential direction of the center tube 100, the injection ports 110 in the same circumferential direction are opened at a predetermined distance, or
The slot-shaped injection ports 110 extend in the axial direction of the center tube 100, and the injection ports 110 in the same axial direction are opened at predetermined distances.
In the technical solution adopted in this embodiment, by setting the shape of the injection ports 110 to be a groove shape, the coverage area of the water flow injected from each injection port 110 can be increased, and a planar cleaning water flow can be formed. The predetermined distance between the injection ports 110 is to prevent the water injection from crossing each other, thereby affecting the injection force and direction of the water flow and the cleaning effect. The specific length of the predetermined distance needs to be determined according to the specific length and width of the groove-like structure.
Further, referring to fig. 4, the disassembly-free heat exchanger further includes a cleaning ball 500, and the cleaning ball 500 is connected to the central tube 100 through the injection port 110.

Of course, in order to prevent the crossing of the water jet streams, the cleaning balls 500 also need to be spaced apart by a predetermined distance. However, unlike the groove-shaped washing port, since the washing balls 500 are rotated, water flow crossing may occur between two adjacent washing balls 500, but since the rotation speed is different, the water flow crossing position is not fixed, and thus even if water flow crossing occurs, a great influence is not brought about on the overall washing effect. It can be appreciated that the cleaning balls 500 can also generate turbulence effect on the heat exchange medium, so as to improve heat exchange efficiency.
The cleaning ball 500 may be provided with a circular nozzle or a groove-shaped nozzle, and is not limited thereto.
Of course, the cleaning ball 500 may be provided on the central tube 100, the injection port 110 may be provided, or both the cleaning ball 500 and the injection port 110 may be provided.

Further, the heat exchange tube 400 is fixedly connected to the center tube 100.
