Description

Technical Field

[0001] This invention relates to the field of heating system technology, specifically to an intelligent upgrading and renovation system for old heating systems. Background Technology

[0002] As my country’s urbanization process continues to advance, many older residential communities built earlier are still using traditional centralized heating systems. Due to factors such as aging pipe networks, unreasonable layout, and low equipment efficiency, they generally suffer from prominent problems such as poor heating effect, high energy consumption, weak control capabilities, and great difficulty in renovation, which can no longer meet the current needs of residents for comfortable heating and energy conservation. First, the heating pipe networks in old residential areas generally suffer from pipe corrosion, blockage, and leakage, resulting in high water flow resistance and slow circulation speed. This easily leads to a large temperature difference between the inlet water temperature and the return water temperature, resulting in low heat transfer efficiency and difficulty in achieving the required indoor temperature. The problem of insufficient heating is particularly prominent in the top-floor and end-point residents. At the same time, traditional systems lack flow control methods, which can easily lead to some users "privately installing circulation pumps to steal water," resulting in uneven heating between buildings and households and affecting the overall heating effect. Secondly, most of the existing old radiators have fixed structures and single functions. They can only passively dissipate heat by relying on the central heating source and have no ability to replenish heat or provide independent heating. When the temperature of the central heating source is insufficient, the heating is unstable, or the supply is interrupted, they cannot provide effective temperature compensation, resulting in a poor heating experience for residents.

[0014] This invention proposes an intelligent upgrade and renovation system for aging heating systems. This system enables intelligent and convenient renovation of heating systems in older residential communities. By replacing the existing aging radiators with this new equipment, it utilizes the water pressure of the central heating system for water circulation, providing indoor heating. The equipment allows operators to set the inlet water flow rate, thereby increasing the return water velocity using a pump in the middle of the unit. This achieves overall heat utilization, raises indoor temperature, prevents large temperature differences between inlet and return water, and avoids water shortages for other residents. Simultaneously, the equipment is equipped with a temperature detector. Through intelligent detection, appropriate electric or gas heating components can be installed to assist in heating the inlet water, further increasing indoor heating temperature. It also allows for the disconnection of central heating, enabling independent heating. Meanwhile, the left side of the equipment… The first and second heating components on the right sides can be swapped in position and two sets of electric heating components can be installed according to actual needs, forming a multi-mode, multi-functional intelligent heating system. Regardless of whether electric or gas heating is used, the first and second heating components on the left and right sides can be connected through the flue pipe, thereby connecting the heat pipes on both sides. This helps to raise the temperature of both the inlet and outlet water, maintaining the temperature supply. Moreover, shoe racks, towel racks, etc. can be installed on the horizontal wall of the flue pipe for drying. If electric heating components are used in series through the flue pipe, heat transfer oil is injected into the heat pipes at both ends to assist in raising the temperature on both sides. If gas heating is used, the flow of flue gas is achieved through the heat pipes and the flue pipe, realizing the utilization of the heat energy of the flue gas. In summary, the beneficial effects of this invention are as follows: 1. The mechanical structure is simple, making it convenient and easy to implement for the renovation of heating systems in old residential areas. It can directly replace the existing old heating systems without major changes to the pipe network, resulting in low construction costs.

[0015] 2. The left and right heating components can be interchanged to adapt to different house types and pipe layouts.

[0016] 3. It can utilize the natural circulation of water pressure in the central heating system, providing heating without relying on electricity. The water inlet flow rate can be manually set to prevent one household from competing for water and affecting other households. The central pump actively increases the return water flow rate, reduces the temperature difference between the supply and return water, and significantly improves the overall heat utilization rate, resulting in a more stable and higher indoor temperature.

[0017] 4. Built-in temperature detector enables intelligent temperature monitoring. It can be heated by electricity or gas, and can flexibly supplement the temperature. It supports both centralized heating and independent heating modes, and can still provide heating even when the power supply is interrupted.

[0018] 5. It can be equipped with two sets of electric heating elements, which have a stronger heating capacity and are suitable for extremely cold weather; it adopts electric heating mode: heat transfer oil is circulated in series and heated on both sides simultaneously; it adopts gas heating mode: waste heat of flue gas is recovered and utilized, so that heat is not wasted, and the inlet and outlet of the water outlet provide bidirectional auxiliary heating for more uniform heating.

[0019] 6. The flue can be fitted with shoe racks and towel racks, and also has a drying function. It integrates multiple modes and functions, and one set of equipment can meet a variety of heating needs. Attached Figure Description

[0023] Please see Figures 1-13 This invention provides a technical solution: an intelligent upgrade and renovation system for an old heating system, comprising a main structure 1, a first heating structure 2, and a second heating structure 3; the first heating structure 2 is detachably embedded in the left side of the main structure 1, and the second heating structure 3 is detachably embedded in the right side of the main structure 1, wherein the positions of the first heating structure 2 and the second heating structure 3 can be interchanged and adjusted according to the actual layout; the main structure 1 is used for intelligent control and drive, and can effectively improve the return flow rate; the first heating structure 2 can be set to auxiliary electric heating or gas heating according to needs, thereby providing temperature compensation for the substandard temperature of centralized heating, and can also achieve independent heating; the second heating structure 3 can be installed and adjusted according to the auxiliary method of the first heating structure 2.

A pair of partitions 15 are fixedly embedded in the control box 14, dividing the control box 14 into three chambers. The controller body 16 is fixedly inserted into the top chamber of the control box 14 and is connected to one of the partitions 15. The pump body 17 is fixedly installed on the other partition 15. The liquid inlet end of the pump body 17 passes through the partition 15 through the first pipe 51, and the first pipe 51 is close to the right side wall of the control box 14. The liquid outlet end of the pump body 17 is provided with a second pipe 52, and the second pipe 52 passes through the right side of the control box 14. The filter cover 18 is detachably fastened to the front bottom of the control box 14, sealing the bottom chamber. A pair of slots 53 are provided on the rear side wall of the filter cover 18, and one end of each pair of filter screens 19 is respectively fastened to the slots 53 of the filter cover 18. The filter screens 19 are inserted below the partition 15. Heating water is supplied through the inlet flow valve 12 on the left side wall of the heating box 11, and the flow rate is adjusted before entering the system through the connection port 41. The heating box 11 is wall-mounted using hooks 13 and hanging slots 44 on the rear wall, providing stable installation support for the equipment. The control box 14 is divided into three independent chambers by a pair of partitions 15. The controller body 16 in the top chamber serves as the control core, controlling the pump body 17, ... The temperature detection and intelligent control of the heating components are achieved. The pump body 17 in the middle chamber draws water through the first pipe 51 and pressurizes and delivers the water to the corresponding heating components through the second pipe 52, actively improving the water circulation and return speed. The bottom chamber is sealed by a removable filter cover 18, and the filter screen 19 installed in its slot 53 filters impurities in the water along the water flow path to prevent pipe blockage and facilitate cleaning. The connection ports 41 on the left and right side walls of the heating box 11 are used to connect with the heating components to achieve water circuit connection, and the heat conduction holes 42 on the upper wall are used to cooperate with the heating components to achieve heat conduction. The first flow holes 43 on both sides of the bottom of the control box 14 ensure stable flow of heating water between the main body and the heating components.

[0025] As a preferred embodiment, the first heating structure 2 further includes a first heating component 21, an electric heating component 22, and a gas component 23. The first heating component 21 is detachably inserted into the left end of the heating box 11 and communicates with the first flow hole 43 on the left side of the control box 14. The electric heating component 22 is detachably fastened to the upper wall of the left end of the heating box 11 and is connected to the first heating component 21. The gas component 23 is detachably fastened to the upper wall of the left end of the heating box 11 and is connected to the first heating component 21. The gas component 23 can be interchanged with the electric heating component 22. The first heating component 21 is detachably inserted into the left end of the heating box 11 and communicates with the first flow hole 43 on the left side of the control box 14. The first flow hole 43 on the left side of the control box 14 forms a water channel connection with the main structure 1, constituting a heating water flow path. According to the on-site energy conditions and usage requirements, an electric heating component 22 or a gas component 23 can be selectively installed at the corresponding position on the upper left side of the heating box 11. Both heating components are precisely connected to the first heating component 21 to achieve heat transfer. The electric heating component 22 and the gas component 23 adopt the same interface and interchangeable installation design. The heat source can be switched without modifying the first heating component 21 and the main structure 1. The heating water flowing through the first heating component 21 is heated by electric heating or gas heating to provide temperature compensation or an independent heating heat source for the system.

[0026] More specifically, by using the first heating component 21 as a universal basic carrier in the first heating structure 2, and combining it with the modular design of the interchangeable electric heating component 22 and gas component 23, the basic heat dissipation function and auxiliary heating function are decoupled. This allows the system to adapt to different on-site energy conditions without modifying the main structure 1 and the original indoor heating pipes. At the same time, the electric heating component 22 and gas component 23 adopt a unified installation interface and quick-connect structure, which greatly reduces the difficulty and cost of heat source switching and subsequent maintenance. In addition, through the linkage control of the temperature detector 214 and the controller body 16, the intelligent start and stop of auxiliary heating is realized. It can automatically provide temperature compensation when the central heating temperature is insufficient, and can also switch to a fully autonomous heating mode when the central heating is stopped, which significantly improves the applicability, reliability and heating comfort of the system.

[0027] As a preferred embodiment, the first heating component 21 further includes a heating box 211, several heat-conducting pipes 212, a manifold 213, a temperature detector 214, and a heat dissipation cover 215. The heating box 211 is detachably embedded in the left end of the heating box 11, and the left side wall of the heating box 211 is provided with a first water inlet 61 corresponding to the connection port 41 on the left side wall of the heating box 11. The first water inlet 61 is connected to one end of the water inlet flow valve 12 through a pipe. The bottom of the right side wall of the heating box 211 is provided with a first water outlet 62 that is connected to the first flow hole 43 on the left side wall of the control box 14. One end of each of the several heat-conducting pipes 212 is fixed. A heat pipe 212 is fixedly installed through the upper wall of the heating box 211, with the other end of the heat pipe 212 located above the first water outlet 62. Several heat pipes 212 are respectively aligned with heat conduction holes 42. One end of the manifold 213 is connected to the other end of the heat pipe 212, and the other end of the manifold 213 is located on the front side of the heating box 211. A temperature detector 214 is fixedly installed on the right side wall inside the heating box 211. A heat dissipation cover 215 is detachably fastened to the front side of the heating box 211, and the heat dissipation cover 215 is sealed and fitted onto the other end of the manifold 213. Several heat dissipation blades are equidistantly arranged on the front side wall of the heat dissipation cover 215. The heat dissipation cover 215 is detachably embedded through the heating box 211. The heating chamber 211 is fixed inside the left end of the heating box 11. Heating water enters the first inlet 61 on the left side wall of the heating box 211 through the connection port 41 of the heating box 11. The first inlet 61 is connected to the inlet flow valve 12 via a pipe, enabling controllable delivery of the inlet flow. The heating water circulates within the internal chamber of the heating box 211. A temperature detector 214 on the right side wall of the heating box 211 monitors the water temperature in real time, providing a detection signal for intelligent temperature control. Several heat-conducting pipes 212 are installed through the upper wall of the heating box 211, corresponding one-to-one with the heat-conducting holes 42 on the upper wall of the heating box 11. The lower ends of the heat-conducting pipes 212 extend into the interior of the heating box 211 and are located above the first outlet 62. The heating element 211 can efficiently transfer the heat generated by the electric heating element 22 or the gas heating element 23 to the heating water in the heating box 211 to achieve auxiliary heating of the water. The manifold 213 is connected to the upper end of each heat pipe 212 to realize the collection and flow of heat transfer medium or flue gas. The heat dissipation cover 215 fastened to the front side of the heating box 211 forms a seal on the front end of the manifold 213. At the same time, the heat dissipation area is increased by the heat dissipation fins on the front side wall to enhance the heat dissipation effect. The heated water flows out through the first outlet 62 at the bottom of the right side wall and enters the main structure 1 through the first flow hole 43 on the left side of the control box 14 to complete the heating and water circulation process.

[0028] More specifically, by using a heating box 211 as the core carrier, the first heating component 21 integrates water circuit connection, temperature detection, heat conduction, and heat dissipation functions into a modular design, enabling rapid assembly and disassembly with the heating box 11 and the main structure 1. This significantly reduces the construction difficulty and subsequent maintenance costs of heating system renovation in old residential areas. Furthermore, by placing the lower end of the heat-conducting pipe 212 above the first water outlet 62, it ensures that all heating water flowing through the heating box 211 can fully contact and exchange heat with the heat-conducting pipe 212 before flowing out, significantly improving heating efficiency. The auxiliary heating thermal efficiency; through the universal structural design of the manifold 213, it can be adapted to both heat transfer oil circulation and flue gas diversion working modes, providing a core foundation for the rapid and unmodified interchange of the electric heating component 22 and the gas component 23; combined with the precise water temperature monitoring of the temperature detector 214 and the enhanced heat dissipation structure of the heat dissipation cover 215, it not only ensures the accuracy and response speed of the system's intelligent temperature control, but also improves the heat dissipation effect of basic heating, thus achieving high versatility, high thermal efficiency and high reliability of the first heating component 21.

[0029] As a preferred embodiment, the electric heating assembly 22 further includes an electric connection box 221, several heating rods 222, an oil seal plate 223, and an oil drain valve 224. The electric connection box 221 is detachably fastened to the left end of the upper wall of the heating chamber 11 and is located at the heat conduction hole 42. Several heating rods 222 are respectively connected to the electric connection box 221, and the heating rods 222 are movably inserted into the heat conduction pipe 212. The oil seal plate 223 is detachably fastened to the other end of the manifold 213, and one end of the oil drain valve 224 is fixedly set in the middle of the oil seal plate 223. The electric connection box 221 is detachably fastened to the heat conduction hole 42 at the left end of the upper wall of the heating chamber 11, and is connected to an external electric... The power supply is connected; several electric heating rods 222 are driven to generate heat by the electric connection box 221 and are respectively movably inserted into the heat conduction pipes 212 of the first heating component 21, converting electrical energy into heat energy and transferring it to the heat conduction oil in the heat conduction pipes 212; the oil seal plate 223 is detachably sealed and fastened at the end of the manifold box 213 to prevent heat conduction oil leakage and ensure the heat conduction circuit is sealed; the oil drain valve 224 set in the middle of the oil seal plate 223 is used for the filling, replacement and venting of heat conduction oil, maintaining the normal working state of the heat conduction oil circuit; the heat generated by the electric heating rods 222 is transferred to the interior of the heating box 211 through the heat conduction pipes 212 and heat conduction oil to realize electric auxiliary heating of the heating water.

[0030] More specifically, by adopting the pluggable structure design of the electric heating component 22 with the integrated electric heating rod 222 in the electric junction box 221, it is possible to quickly install and replace the first heating component 21 without modifying the main structure 1 and the original indoor heating pipes, which greatly reduces the installation and maintenance costs of the electric heating function. By directly inserting the electric heating rod 222 into the heat transfer pipe 212 and directly exchanging heat with the heat transfer oil, heat loss in the intermediate heat exchange link is eliminated, which significantly improves the thermal efficiency of electric heating. With the sealing structure of the oil seal plate 223 and the oil filling and draining design of the oil drain valve 224, the airtightness of the heat transfer oil circuit is ensured, preventing heat transfer oil leakage from causing safety hazards, and facilitating the periodic replacement of heat transfer oil and the venting of the circuit, thus extending the service life of the system. At the same time, the electric heating component 22 and the gas component 23 adopt a unified installation interface, which can flexibly switch the heat source according to the on-site energy conditions, further improving the applicability and versatility of the system.

The electrically controlled ignition valve 233 is fixedly installed on the front side wall of the gas collection box 231, and the electric ignition of the electrically controlled ignition valve 233 is located inside the gas collection box 231. Both ends of the gas guide pipe 234 are connected to the gas inlet of the explosion-proof diverter pipe 232. The gas is fed to the outlet of the electric flame valve 233 and the outlet of the gas collection box 231, which is detachably attached to the heat conduction hole 42 on the left side of the upper wall of the heating box 11 to form a gas combustion and flow space. The gas is controlled by the electric flame valve 233 to control the on / off and flow rate, and is delivered to the explosion-proof diversion pipe 232 through the gas guide pipe 234. The explosion-proof diversion pipe 232 evenly distributes the gas and sprays it out through several nozzles corresponding to the heat conduction hole 42. The electric ignition end of the electric flame valve 233 generates an ignition spark inside the gas collection box 231, which ignites the sprayed gas to form high-temperature flue gas. The flue gas enters the heat conduction pipe 212 through the heat conduction hole 42 and heats the heating water in the heating box 211 by flue gas heat exchange, realizing gas-assisted heating.

[0032] More specifically, the modular design of the gas component 23, which uses a unified installation interface with the electric heating component 22, enables rapid and unmodified interchange of the two heat sources, allowing the system to flexibly adapt to the energy supply conditions of different communities. The uniform flow distribution structure of the explosion-proof diversion pipe 232 ensures consistent combustion intensity of the gas in each heat-conducting pipe 212, avoiding localized overheating or uneven heating and improving the stability and safety of the system. The direct entry of high-temperature flue gas into the heat-conducting pipe 212 for heat exchange with the heating water eliminates heat loss in intermediate heat exchange stages, significantly improving the thermal efficiency of gas heating. The series connection between the flue gas duct 34 and the second heating component 31 enables secondary recovery and utilization of waste heat from the flue gas, further reducing gas consumption. Simultaneously, the electrically controlled electric ignition valve 233 achieves integrated intelligent control of gas on / off, flow regulation, and automatic ignition, eliminating the need for manual operation, thus improving the system's automation and safety. Furthermore, the overall installation and maintenance process requires no modification to the existing heating pipelines, making it particularly suitable for the low-cost, rapid renovation needs of older communities.

[0033] As a preferred embodiment, the second heating structure 3 further includes a second heating component 31, a solenoid valve 32, a water pipe 33, a smoke pipe 34, a smoke collection box 35, and a smoke exhaust pipe 36. The second heating component 31 has the same structure as the first heating component 21. The second heating component 31 is detachably embedded in the right end of the heating box 11, and the second heating component 31 is connected to the first flow hole 43 on the right side wall of the control box 14. The solenoid valve 32 is fixedly installed in the heating box 211 of the second heating component 31, and one end of the solenoid valve 32 is connected to the control box 14 through a pipe. 4. The first flow hole 43 at the bottom of the right side wall is connected. One end of the water guide pipe 33 is connected to the solenoid valve 32. The water guide pipe 33 is a T-shaped pipe. The other end of the water guide pipe 33 is fixedly inserted through the left side wall of the second heating component 31 and connected to the second pipe 52 at the outlet of the pump body 17. The two ends of the smoke guide pipe 34 are respectively connected to the other end of the manifold 213 in the first heating component 21 and the second heating component 31. The smoke collection box 35 is fastened to the upper right wall of the heating box 11 and fastened to the heat conduction hole 42. The exhaust pipe 36 is connected to the smoke collection box 35. Through the second heating component Component 31 adopts the same structure as the first heating component 21, and is detachably installed inside the right end of the heating box 11. It forms a water circuit with the main structure 1 through the first flow hole 43 on the right side of the control box 14, thus forming a symmetrical heating water circulation path on both sides. The solenoid valve 32 is fixed inside the heating box 211 of the second heating component 31. One end of the valve is connected to the first flow hole 43 at the bottom right side of the control box 14 through a pipe, and the other end is connected to the T-shaped water guide pipe 33. The other end of the water guide pipe 33 passes through the left side wall of the second heating component 31 and connects to the pump body. The second pipe 52 at the outlet of 17 is connected to the pump body 17 and the solenoid valve 32 is switched to achieve the switching between forced circulation and natural water pressure circulation modes. The two ends of the flue gas duct 34 are respectively connected to the manifold 213 of the first heating component 21 and the second heating component 31, forming a heat transfer medium or flue gas circulation channel that runs through the left and right sides. The flue gas collection box 35 on the upper right side of the heating box 11 is fastened to the heat transfer hole 42 to collect the flue gas and safely discharge the flue gas after waste heat utilization through the exhaust pipe 36, completing the double-sided heat exchange and flue gas flow and discharge process.

[0034] During system operation, the controller body 16 controls the start and stop of the pump body 17 and the on / off state of the solenoid valve 32 to achieve automatic switching between two water circulation modes: Natural water pressure circulation mode: When the central heating water pressure is sufficient and the temperature difference between the supply and return water is small, the controller body 16 controls the pump body 17 to stop running and simultaneously opens the solenoid valve 32. After the heating water is cooled by the first heating component 21, it flows into the filter chamber at the bottom of the control box 14. After impurities are filtered by the filter screen 19, it flows into the solenoid valve 32 through the first flow hole 43 on the right side wall of the control box 14, and then enters the heating box 211 of the second heating component 31 for secondary heat dissipation through the solenoid valve 32. Finally, it flows out to the outdoor return water pipe through the connection port 41 on the right side wall of the second heating component 31, completing the natural circulation process.

[0035] Forced pressurization circulation mode: When the central heating water pressure is insufficient, the return water flow rate is too slow, or the temperature difference between the supply and return water is too large, the controller body 16 controls the pump body 17 to start running, and at the same time closes the solenoid valve 32. The pump body 17 draws filtered heating water from the filter chamber at the bottom of the control box 14 through the first pipe 51, and after pressurization, it is transported to the T-shaped water guide pipe 33 through the second pipe 52, and then directly injected into the heating box 211 of the second heating component 31 through the water guide pipe 33, actively increasing the water circulation speed of the entire system, reducing the temperature difference between the supply and return water, and improving the heat utilization rate.

[0036] When the system adopts the electric heating assisted mode, the flue pipe 34, together with the heat pipes 212 on the left and right sides and the manifold 213, forms a closed heat transfer oil circulation loop. After the electric heating rod 222 heats the heat transfer oil in the heat pipe 212 of the first heating component 21, the heated heat transfer oil flows into the heat pipe 212 of the second heating component 31 through the flue pipe 34 under the action of density difference, synchronously heating the heating water in the second heating component 31. The cooled heat transfer oil then flows back to the heat pipe 212 of the first heating component 21 through the flue pipe 34, forming a natural convection circulation and realizing simultaneous heating on both sides.

[0037] When the system adopts the gas-fired heating-assisted mode, the flue gas duct 34, together with the heat-conducting pipes 212 on the left and right sides and the manifold box 213, constitutes the flue gas circulation channel. The high-temperature flue gas generated by gas combustion first undergoes heat exchange in the heat-conducting pipe 212 of the first heating component 21. The medium-temperature flue gas after heat exchange flows into the flue gas duct 34 through the manifold box 213 of the first heating component 21, and then enters the heat-conducting pipe 212 of the second heating component 31 for secondary waste heat recovery. Finally, the low-temperature flue gas after two heat exchanges flows into the flue gas collection box 35 through the manifold box 213 of the second heating component 31, and is safely discharged to the outside through the exhaust pipe 36, realizing the cascade utilization of flue gas heat energy.

[0038] As a preferred embodiment, the pump body 17 is further connected to the water pipe 33 via the second pipe 52, so that when the pump body 17 is driven, it delivers liquid to the second heating component 31, and at this time the solenoid valve 32 is closed; when the pump body 17 stops driving, the solenoid valve 32 is opened, and the liquid is automatically delivered by water pressure; the heat transfer pipe 212, the manifold 213 and the flue gas pipe 34 can all be injected with heat transfer oil or delivered by flue gas.

[0039] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0040] When the system is working, the main structure 1 serves as the foundation for overall control and circulation: heating water enters the system through the connection port 41 after the flow rate is regulated by the inlet flow valve 12 on the left side of the heating tank 11; the heating tank 11 is wall-mounted and fixed by the rear wall hook 13 and the hanging groove 44 to ensure stable installation; the control box 14 is divided into three independent chambers by a pair of partitions 15, the controller body 16 in the top chamber provides unified intelligent control, the pump body 17 in the middle chamber draws water through the first pipe 51 and pressurizes the water through the second pipe 52 to achieve forced water circulation; the bottom chamber of the control box 14 is sealed by the filter cover plate 18, and the filter screen 19 is clipped into the slot 53 to continuously filter the water, prevent pipe blockage, and facilitate disassembly and cleaning; heat conduction holes 42 are opened on the upper wall of the heating tank 11, and first flow holes 43 are provided on both sides of the bottom of the control box 14 to ensure smooth connection between the water circuit and the heat conduction circuit; The first heating structure 2 realizes the main heating function: the heating box 211 of the first heating component 21 is detachably embedded in the left end of the heating box 11. The heating water enters through the first water inlet 61 and the water temperature is monitored in real time by the temperature detector 214. Multiple heat conduction pipes 212 pass through the upper wall of the heating box 211 and correspond to the heat conduction holes 42. The manifold 213 connects the upper ends of each heat conduction pipe 212. The heat dissipation cover 215 is fastened and sealed and assists in heat dissipation. The heated water flows into the control box 14 through the first water outlet 62 and the first flow hole 43. When the temperature detector 214 detects that the water inlet temperature and the water outlet temperature on the left and right sides are not up to standard, the controller body 16 on the control box 14 drives the corresponding auxiliary heating device to raise the temperature. When the electric heating element 22 is selected, the electric connection box 221 is fastened to the upper left wall of the heating box 11, the electric heating rod 222 is inserted into the heat conduction pipe 212 to generate heat, the oil seal plate 223 seals the manifold 213, and the oil drain valve 224 is used for adding and replacing heat conduction oil. When gas assembly 23 is selected, gas collection box 231 is fastened to the upper left wall of heating box 11. Gas is controlled by electric fire valve 233 and sent into explosion-proof diversion pipe 232 through gas pipe 234. It is injected into heat conduction 212 through heat conduction hole 42 and ignited to achieve temperature rise by heating with flue gas. The second heating structure 3 achieves auxiliary coordination and dual-sided heating: the second heating component 31 has the same structure as the first heating component 21, and is detachably embedded in the right end of the heating box 11 and connected to the first flow hole 43 on the right side; the solenoid valve 32 is installed inside the second heating component 31 and connected to the T-shaped water pipe 33. The other end of the water pipe 33 is connected to the second pipe 52 of the pump body 17. When the pump body 17 starts, the solenoid valve 32 is closed to achieve forced circulation. When the pump body 17 stops, the solenoid valve 32 is opened to achieve natural water pressure circulation. The two ends of the flue duct 34 are connected to the manifold 213 of the first heating component 21 and the second heating component 31 respectively, forming a passage for heat transfer oil or flue gas. The flue duct 35 is fastened to the heat transfer hole 42 on the right end of the heating box 11. After the flue gas is collected by the flue duct 35, it is safely discharged through the exhaust pipe 36, completing the whole process of double-sided heat exchange, waste heat utilization and flue gas discharge.
