It can transfer heat from a high-temperature fluid to a low-temperature fluid, thereby achieving effective utilization and conversion of heat. In HVAC systems, heat exchangers are usually used to heat or cool air, water or other media to quickly transfer and convert heat.

[0003] Prior art 1 (Announcement No.: CN206235194U, Chinese patent published on June 9, 2017) A water storage instant heat exchanger is connected to a header body and a shell and tube, and at least one heating heat exchange tube and one cold water heat absorption tube are arranged in the tube cavity of the shell circular tube part; the pipe mouth at one end of the cold water heat absorption tube is welded to the cold water pipe joint, and the pipe mouth at the other end is welded to the circular ring reinforcement plugging plate to circulate with the inner cavity of the header; the outer plate component of the header wraps the heating heat exchange tube and the cold water heat absorption tube and is sealed and welded to the inner orifice plate of the header at both ends of the multiple shell circular tubes; the end cover plate component is sealed and welded to the inner orifice plate of the header and the port of the outer plate of the header to form a header body; the two media flow through the heating heat exchange tube or / and the multiple shell circular tube cold water heat absorption tubes in the heat exchanger respectively to exchange heat more fully. There is also prior art 2 (Announcement No.: CN105547012B, Chinese patent published on 2020-03-24) a heating pipe interconnection heat exchanger, multiple heating pipe lumens are interconnected, heating connecting straight pipes are sequentially inserted into the pipe interconnection welding holes on multiple heating pipes, and welded in series, and at least one cold water heat exchange pipe is arranged in the lumens of multiple heating pipes. The heat exchange area is large, and the cold water heat exchange pipe is inserted as a whole or inserted into the lumens of multiple heating pipes by bending the pipes. The pipes are welded and connected, with advanced technology and compact structure, which can not only heat and dissipate heat but also exchange hot water, reduce pipe welding joints, are not easy to leak, and have a long product life cycle.

[0004] Although the HVAC systems in the prior art 1 and the prior art 2 can be used for heating, there is no anti-blocking mechanism inside them during the heating process. Impurities in the heating system, such as rust, sand, etc., may also accumulate in the pipes and cause blockages. At the same time, the HVAC system will form scale after long-term use. The scale may still accumulate in the radiator pipes, reducing the flow area of ​​the pipes, thereby affecting the circulation of hot water. There are certain limitations.

During the sliding process, the resistance wheel will be resisted by the raised part of the resistance plate, thereby further driving the knocking block to move inward, knocking on the purification tube body, causing the purification tube body to vibrate, and the residual scale attached to the inner wall of the purification tube body falls to the inside of the ash box for collection under the vibration of the purification tube body, which is convenient for subsequent cleaning. At the same time, a plurality of tortuous parts are arranged on the resistance plate. The knocking block can reciprocately knock on the purification tube body vertically under the elastic action of the spring and the resistance action of the resistance plate, which can further improve the cleaning of the residual scale attached to the inner wall of the purification tube body.
