[0002] Heating equipment is essential for people in winter or in cold regions. Existing heating methods are broadly divided into two types: electric heating and central heating. In cold areas, residential areas are equipped with central heating. Central heating works by heating water, which is then released through radiators. This method provides relatively gentle heat dissipation, but it doesn't allow for control over the direction of the warm airflow. Therefore, it is necessary to design a heating system that can utilize the heat from central heating and allows for directional and centralized control of the warm airflow. Utility Model Content

[0003] This utility model provides a heating device to solve the defect of existing heating devices that can control the direction of warm air but cannot utilize the heat in the heating system. It realizes a heating device that can utilize the heat in the heating system and can control the direction of the warm air flow in a directional and centralized manner.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] The following is combined Figure 1 Describe the structure and working principle of this utility model.

[0034] Reference Figure 1 The present invention provides a heating device comprising a housing 100, a blower component 200, and a heat exchange assembly 300. The housing 100 has an interior cavity 130, with an air outlet 110 at one end and an air inlet 120 at the other end, both communicating with the cavity 130. The blower component 200 is located inside the cavity 130 and forms an airflow within it, flowing from the air inlet 120 towards the air outlet 110. The heat exchange assembly 300 is located in the housing 100 and transfers heat from the heating system to the cavity 130. The air outlet 110 has a first cover for sealing it; the air inlet 120 has a second cover for sealing it.

[0035] Specifically, the various components of the housing 100 can be connected in different ways. A movable assembly is located at the bottom of the housing 100 for moving the housing 100. The side plates and bottom plate of the housing 100 can be bolted together, with a sealing gasket at the joint surface and then tightened with bolts; or they can be welded together, with full welding at the joint to ensure structural strength. The blower component 200 is fixed inside the cavity 130 by a mounting bracket, which is connected to the inner wall of the housing 100 with M8 bolts, and shock-absorbing pads are installed at the connection. The heat exchange component 300 can be connected to the housing 100 by a flange, with flanges installed at the inlet and outlet of the heat exchange component 300, and bolted to the heating pipes; or by a quick-connect coupling, with a clamp-type quick-connect coupling at the pipe interface. The air guide plate at the air outlet 110 is connected to the housing 100 by a rotating shaft, with both ends of the shaft secured by screws with locking function. The air outlet 110 is equipped with a flow guiding component, which is used to adjust the airflow direction at the air outlet 110. The first cover and the second cover can prevent dust from entering the housing 100 when not in use.

[0036] In this embodiment, after the blower component 200 is activated, a negative pressure is created within the cavity 130, causing external air to enter through the air inlet 120. As the air flows through the heat exchange component 300, it exchanges heat with the internally flowing hot water and is heated. The heated air is then discharged from the air outlet 110 under the influence of airflow. The guide vane allows the airflow direction to be adjusted within a certain range, achieving directional air delivery. This structure fully utilizes the heat source of the existing heating system, significantly improving heat exchange efficiency through forced convection. Simultaneously, the centralized air delivery method of the air outlet 110 ensures that heat is precisely transferred to the required area, solving the problem of uneven heat distribution in traditional radiators.

[0037] Reference Figure 1 In some embodiments of this utility model, the heat exchange assembly 300 includes a heat exchanger 310, a return pipe 350, and a water inlet pipe 340. The heat exchanger 310 is disposed inside the cavity 130 and located between the air outlet 110 and the blower component 200; one end of the return pipe 350 is connected to the water inlet of the heat exchanger 310, and the other end is connected to the water supply pipe of the heating system; one end of the water inlet pipe 340 is connected to the water outlet of the heat exchanger 310, and the other end is connected to the return pipe of the heating system. Both the water inlet pipe 340 and the return pipe 350 are equipped with valves 360.

[0038] Specifically, the heat exchanger 310 can be fixed to the housing 100 in two ways: one is by using M6 bolts with mounting brackets, with mounting ears at the four corners of the heat exchanger 310, and the mounting brackets welded to the inner wall of the housing 100; the other is by using a snap-fit ​​fixing structure, with positioning grooves on the inner wall of the housing 100 and elastic snaps at corresponding positions on the outer shell of the heat exchanger 310. The return pipe 350 can be connected to the heating water supply pipe using a flange connection, employing a DN20 flange with a rubber gasket, and secured with M10 bolts; or a quick-connect coupling, using a self-locking copper quick-connect coupling. The connection method between the inlet pipe 340 and the heating return pipe is the same as that of the return pipe 350, ensuring the sealing and reliability of the water connection. Polytetrafluoroethylene (PTFE) sealing rings are installed at the inlet and outlet connections of the heat exchanger 310 to prevent leakage.

[0039] In this embodiment, hot water from the heating system enters the heat exchanger 310 through the return pipe 350, releases heat within the heat exchanger 310, and then returns to the heating system through the inlet pipe 340. The airflow generated by the blower component 200 is heated as it passes through the heat exchanger 310, forming hot air that is discharged from the outlet 110. The heat exchanger 310 employs a multi-pass design, increasing the heat exchange time between the hot water and the air, thus improving thermal efficiency. This structure achieves efficient utilization of heating energy, significantly improving the heating effect through forced convection, while maintaining the original stability and safety of the heating system. The placement of the heat exchanger 310 between the blower component 200 and the outlet 110 ensures that the airflow can fully absorb heat before being discharged.

[0040] In some possible embodiments, a nano-coating, composed of a titanium dioxide and zinc oxide composite material, with a thickness of 50-80 μm, is applied to the fin surface of the heat exchanger 310. The return pipe 350 and the inlet pipe 340 employ a double-layer insulation structure: an inner copper pipe, an outer 10 mm thick aerogel insulation layer, and an outermost stainless steel corrugated pipe for protection. The mounting bracket of the heat exchanger 310 is equipped with a vibration damping device consisting of rubber damping pads and spring dampers, effectively reducing vibration and noise. These improvements increase the heat transfer efficiency of the heat exchanger 310 by approximately 15%, reduce pipe heat loss, and simultaneously reduce vibration and noise during operation, extending the equipment's service life. The double-layer insulation structure also prevents burns from excessively high pipe surface temperatures, improving operational safety.

[0041] Reference Figure 1 In some embodiments of this utility model, the heat exchange assembly 300 further includes a water collection tray 320 and a water pump. The water collection tray 320 is located inside the cavity 130, and the water pump is located inside the water collection tray 320. The water collection tray 320 is connected between the heat exchanger 310 and the return pipe 350, and the water pump is used to pump heating water to the heat exchanger 310.

[0042] Specifically, the pipe connection between the water collection tray 320 and the heat exchanger 310 can be either a flange connection or a welded connection. When a flange connection is used, flanges are installed at the outlet of the water collection tray 320 and the inlet of the heat exchanger 310, and the connection is secured with bolts and graphite composite gaskets. When a welded connection is used, the outlet of the water collection tray 320 and the inlet of the heat exchanger 310 are directly welded together using a welding process, followed by X-ray flaw detection. The water collection tray 320 is fixed inside the housing 100 by a support frame made of L-shaped angle steel, which is bolted to the inner wall of the housing 100, with a high-temperature resistant rubber gasket at the connection point. The return pipe 350 is connected to the inlet of the water collection tray 320 using a compression fitting, with an internal sealing ring and externally secured with a stainless steel compression nut.

[0043] In this embodiment, hot water from the heating system enters the water collection pan 320 through the return pipe 350 and is then transported to the heat exchanger 310 via pipelines. The water collection pan 320 serves to stabilize pressure and distribute the hot water, ensuring that the hot water enters each flow channel of the heat exchanger 310 evenly. After releasing heat, the hot water in the heat exchanger 310 returns to the heating system through the inlet pipe 340. The airflow generated by the blower component 200 is fully heated as it flows through the heat exchanger 310, forming a stable stream of hot air that is discharged from the outlet 110. This structure, through the pressure stabilizing effect of the water collection pan 320, makes the heat exchange process more stable, reduces the impact of water flow pulsation on heat exchange efficiency, and also reduces system operating noise.

[0044] In some possible embodiments, a porous buffer plate with a honeycomb structure is installed inside the water collection tray 320. The connecting pipe between the water collection tray 320 and the heat exchanger 310 has a double-layer structure, with an inner copper pipe and an outer polyurethane insulation layer. A magnetic level gauge is installed at the bottom of the water collection tray 320 for observing the water level. An expansion joint, consisting of a stainless steel corrugated pipe and a flange, is installed at the interface between the connecting pipe and the heat exchanger 310. These improvements make the water flow distribution more uniform, reduce heat loss, facilitate observation of the system's operating status, and effectively compensate for the stress caused by thermal expansion and contraction. The honeycomb buffer plate makes the water flow more stable, avoids the generation of eddies, and improves heat exchange efficiency. The double-layer insulated pipe structure significantly reduces heat loss and improves energy utilization.

[0045] Reference Figure 1 In some embodiments of this utility model, a heater 330 is provided inside the water collection tray 320.

[0046] Specifically, the heater 330 is connected to the water collection tray 320 via a flange fixing method. Mounting holes are provided on the side wall of the water collection tray 320. The mounting flange of the heater 330 is connected to the water collection tray 320 using M6 stainless steel bolts, and a high-temperature resistant silicone gasket is used for sealing the connection surface. The power cord of the heater 330 is led out through a waterproof connector, which uses a threaded connection structure with an IP67 protection rating. The heater 330 can be a tubular heater or a plate heater. The tubular heater is fixed to the inner wall of the water collection tray 320 using U-bolts, while the plate heater is fixed to the bottom of the water collection tray 320 by welding. A temperature sensor mounting bracket is provided at the heater 330 mounting position in the water collection tray 320, and the temperature sensor is fixed by a threaded connection.

[0047] In this embodiment, when the water supply temperature of the heating system is insufficient, the heater 330 is activated to provide auxiliary heating to the water in the collection pan 320. After hot water enters the collection pan 320 via the return pipe 350, it is first temperature-compensated by the heater 330 before being delivered to the heat exchanger 310. This structure ensures that the water temperature entering the heat exchanger 310 remains within the optimal operating temperature range even under extreme low-temperature conditions. The airflow generated by the blower component 200 is stably heated as it flows through the heat exchanger 310, ensuring the stability of the air supply temperature at the air outlet 110. The heater 330 allows the heating device to adapt to a wider range of ambient temperatures, improving the reliability of system operation.

[0048] In some possible embodiments, heat-conducting fins are provided on the surface of heater 330. The fins are made of aluminum and are tightly bonded to the heating tube using a tube expansion process. A guide plate is installed inside the water collection tray 320, and the guide plate is spirally distributed to create turbulence when the water flows through heater 330. The power cord of heater 330 is armored, and the protective layer is wrapped with stainless steel corrugated tubing. A magnesium alloy sacrificial anode is installed in the heating area of ​​water collection tray 320 to prevent electrochemical corrosion. These improvements increase the heat exchange efficiency of heater 330 by more than 20%, the guide plate structure makes the water temperature more uniform, the armor protection improves electrical safety, and the sacrificial anode extends the service life of water collection tray 320. The spiral guide plate design ensures full contact between the water flow and heater 330, avoiding localized overheating.

[0049] Reference Figure 1 In some embodiments of this utility model, the heating device further includes a heating component 400, which is disposed inside the cavity 130 and located between the air outlet 110 and the blower component 200.

[0050] Specifically, the heating element 400 is connected to the housing 100 as follows: the heating element 400 is fixed inside the cavity 130 by a stainless steel mounting bracket. The mounting bracket is connected to the inner wall of the housing 100 using M8 stainless steel bolts, and an asbestos rubber gasket is placed at the connection point. The power interface of the heating element 400 uses a waterproof socket with an IP65 protection rating and is connected to an external power source via a high-temperature resistant silicone cable. The heating element 400 can be equipped with either a finned heating tube or a PTC ceramic heating element. The finned heating tube is bolted to the mounting bracket via an end flange, while the PTC ceramic heating element is fixed to the mounting bracket using a special clamp. A certain distance is maintained between the heating element 400 and the heat exchange assembly 300, and this distance is precisely controlled by a positioning block.

[0051] In this embodiment, the heating element 400 serves as an auxiliary heat source, activating when the heat exchange component 300 provides insufficient heat. The blower component 200 first preheats the air by passing it through the heat exchange component 300, then reheats it by passing it through the heating element 400, ensuring that the air temperature at the outlet 110 reaches the set value. The heating element 400 enables the device to maintain stable heating capacity even under extreme low-temperature conditions, while also shortening the preheating time. This dual heating system retains the energy-saving and environmentally friendly advantages of traditional heating systems while providing rapid-response auxiliary heating capabilities, allowing the heating device to adapt to a wider range of climatic conditions and usage needs.

[0052] In some possible embodiments, the mounting bracket of the heating element 400 is equipped with a thermal expansion compensation structure, which consists of a stainless steel bellows and a spring, to absorb stress generated by thermal expansion and contraction. A heat-insulating reflector is installed around the heating element 400, made of aluminum foil composite ceramic fiber material. The power cord of the heating element 400 is equipped with a dual temperature protection device, including a resettable temperature control switch and a fuse. This configuration makes the hot air distribution more uniform, reduces the impact of thermal stress on the structure, and improves thermal efficiency and operational safety. The airflow equalization plate effectively improves the uniformity of the outlet air temperature, the heat-insulating reflector reduces the surface temperature of the housing 100, and the dual protection devices ensure electrical safety.

[0053] Reference Figure 1 In some embodiments of this utility model, the air inlet 120 is detachably equipped with a filter screen 500.

[0054] Specifically, the connection between the filter 500 and the air inlet 120 can be either a sliding groove type or a magnetic adsorption type. When using a sliding groove type connection, a U-shaped guide groove is provided on the inner side of the air inlet 120, and the frame of the filter 500 has a flange that mates with the guide groove. When using a magnetic adsorption type connection, a permanent magnet is embedded in the frame of the filter 500, and the frame of the air inlet 120 is made of a magnetically adsorbable metal material. The frame of the filter 500 is made of stamped metal sheet, with filter material sandwiched inside, and the filter material is fixed within the frame by a pressure strip. The frame of the air inlet 120 can be equipped with a sealing strip made of foamed rubber material, forming a sealed interface during filter 500 installation.

[0055] In this embodiment, the filter 500 filters the air entering the cavity 130, effectively blocking airborne particles. When the blower component 200 is running, outside air enters the cavity 130 after being filtered by the filter 500 at the air inlet 120. The clean air flows through the heat exchange component 300 and the heating component 400 before being discharged from the air outlet 110. This structure prevents dust from accumulating on the surface of the heat exchange component 300, maintaining heat exchange efficiency, and preventing pollutants from spreading into the room with the warm air. The removable design of the filter 500 facilitates regular maintenance and ensures a continuous and stable filtration effect.

[0056] In some possible embodiments, a pre-filter layer is added to the air inlet side of the filter 500. This pre-filter layer uses coarse filter material and is detachably fixed to the frame of the main filter 500. The frame of the filter 500 has a raised structure for easy gripping, and the raised surface has anti-slip textures. An installation status indicator for the filter 500 is provided on the frame of the air inlet 120, providing a visual indication when the filter 500 is not installed correctly. A dust collection structure may be provided at the bottom of the filter 500 frame, and this dust collection structure is detachable. This embodiment forms a multi-stage filtration system, extending the service life of the main filter 500, facilitating the installation and removal of the filter 500, improving reliability with the installation status indicator, and reducing secondary pollution during maintenance with the dust collection structure. The pre-filter layer effectively intercepts larger particles, reducing the burden on the main filter 500.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
