[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Well-known modules, units and their connections, links, communications or operations therebetween are not shown or not described in detail. And the described features, architectures or functions can be combined in any way in one or more embodiments. Those skilled in the art should understand that the following various embodiments are only used for illustration, rather than for limiting the protection scope of the present utility model. It can also be easily understood that the modules, units or processing methods in the various embodiments described herein and shown in the drawings can be combined and designed in various different configurations. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0040] For the definitions of various nouns or methods referred to in the following embodiments, unless it is logically impossible to hold, the nouns or methods generally refer to the broad concepts that can be implemented on the premise of the content disclosed in the embodiments. Under such an understanding, various specific subordinate specific definitions of the nouns or methods should be regarded as the content of the present utility model of the present utility model, and should not be narrowly understood or prejudicially interpreted on the grounds that the specific definition is not disclosed in the specification. Similarly, on the premise that it can be logically realized, the order of the steps in the method is flexible and changeable, and the specific subordinate specific definitions in the broad concepts of various nouns or methods belong to the protection scope of the present utility model.

[0041] The main solution of the embodiment of the present application is as follows: An inner tank is provided, and a water inlet hole and a water outlet hole are provided on the inner tank. Then, a thick film heating component is provided, and the thick film heating component is arranged on the inner tank, so that a water channel is formed between the thick film heating component and the outer wall of the inner tank. Thus, heat is generated when powered on, so that the water flowing through the water channel is heated. In order to ensure the smooth flow of water in the water channel, a water pumping component is provided and arranged inside the inner tank. The water pumping component is respectively communicated with the water inlet hole and the water outlet hole to drive the water to enter the water channel through the water inlet hole. Thus, after being heated under the heat generated by the thick film heating component, it is output to the water outlet hole.

[0042] Since the PTC heat conversion efficiency of the prior art is also not satisfactory, compared with other types of heaters, its energy conversion efficiency is relatively low, resulting in more energy loss during the heating process, thus affecting the overall performance and energy efficiency performance of the heater. These factors make the PTC automotive liquid heater unable to achieve the expected heating effect during use and also unable to meet the growing demands for automotive comfort, energy conservation and environmental protection.

[0043] The present application provides a solution to improve and optimize the heating efficiency and structural design of the automotive liquid heater, and meet the multiple requirements of automotive weight reduction, space optimization, energy conservation and environmental protection.

[0044] Refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the thick film heating device includes an inner tank 100, a thick film heating component 200 and a water pumping component 300, wherein:

[0045] A water inlet hole 110 and a water outlet hole 120 are provided on the inner tank 100; the thick film heating component 200 is arranged on the outer periphery of the inner tank 100; a water channel is formed between the thick film heating component 200 and the outer wall of the inner tank 100; the thick film heating component 200 is used for heating the water in the water channel when powered on; the water pumping component 300 is arranged inside the inner tank 100, and the water pumping component 300 is respectively communicated with the water inlet hole 110 and the water outlet hole 120; the water pumping component 300 is used for driving the water to enter the water channel through the water inlet hole 110, so that after being heated by the thick film heating component 200, it is output to the water outlet hole 120.

[0046] In this embodiment, the inner tank 100 is of a hollow structure, and its material can be selected from materials with high thermal conductivity and corrosion resistance, such as stainless steel or aluminum alloy, to ensure both effective heat transfer and resistance to the erosion of water and possible chemical substances. The shape design of the inner tank 100 needs to optimize the water flow path, reduce the water flow resistance and improve the heating efficiency. At the same time, the surface of the inner tank 100 needs to be specially treated, such as polishing or coating treatment, to reduce the formation of water scale and extend the service life.

[0047] In this embodiment, the thick film heating component 200 can be composed of multiple layers of materials, including a conductive layer and an insulating layer. The conductive layer is made of a material with high resistivity, such as nickel-chromium alloy or platinum-rhodium alloy, to generate a large amount of heat when powered on. The insulating layer is used to prevent current leakage and ensure safety in use. The thick film heating component 200 can be set as a tubular shape, and its conductive layer is directly attached to the tube through specific processes (such as screen printing, laser etching, etc.) to form the thick film heating component 200. Then, the thick film heating component 200 is sleeved outside the inner tank 100, so that a water channel is formed between the outer wall of the inner tank 100 and the inner wall of the thick film heating component 200.

[0048] In addition, as a key component for driving the water flow circulation, the performance of the water pumping component 300 directly affects the heating efficiency. The water pumping component 300 can adopt a water pump 310 driven by a brushless DC motor, and the water pump 310 has the characteristics of high efficiency, low noise, and long service life. The water outlet of the water pump 310 is connected to the water inlet hole 110 of the inner tank 100, and the water inlet is communicated with the water source. By controlling the rotation speed and working time of the water pump 310, the flow rate and temperature of the water flow can be precisely adjusted to meet the requirements in different usage scenarios.

[0049] In this embodiment, by providing the inner tank 100, with a water inlet hole 110 and a water outlet hole 120 provided on the inner tank 100, then providing the thick film heating component 200, and arranging the thick film heating component 200 on the outer periphery of the inner tank 100, so that a water channel is formed between the thick film heating component 200 and the outer wall of the inner tank 100, thereby generating heat when powered on, so that the water flowing through the water channel is heated. In order to ensure the smooth flow of water in the water channel, by providing the water pumping component 300 and arranging the water pumping component 300 inside the inner tank 100, the water pumping component 300 is respectively communicated with the water inlet hole 110 and the water outlet hole 120, to drive the water to enter the water channel through the water inlet hole 110, and then after being heated under the heat generated by the thick film heating component 200, it is output to the water outlet hole 120, so as to improve and optimize the heating efficiency and structural design of the automotive liquid heater, and meet the multiple requirements of vehicle weight reduction, space optimization, and energy conservation and environmental protection.

[0050] Optionally, referring to Figure 3 In another embodiment of the present utility model, a thick film heating device is provided. Based on the above Figure 1 and Figure 2 shown embodiments, the thick film heating component 200 includes a heating tube 210, and a thick film layer 220 is provided on the outer wall of the heating tube 210. The heating tube 210 is sleeved on the outer periphery of the inner tank 100; the thick film layer 220 is used to generate heat when powered on to heat the water flowing through the water channel.

[0051] In this embodiment, the heating tube 210 is made of a material with high thermal conductivity, such as copper or stainless steel. Its inner wall is smooth to reduce water flow resistance. At the same time, the thick film layer 220 on the outer wall is evenly attached through advanced coating technology to ensure uniform heat distribution and efficient heat transfer to the water flow passing through the water channel. The high-resistivity material used in the thick film layer 220 can quickly reach a high-temperature state when powered on, thereby achieving rapid heating of the water flow.

[0052] Optionally, referring to Figure 4 and Figure 5 , another embodiment of the present utility model provides a thick film heating device. Based on the above Figure 1 and Figure 2 shown embodiment, a spiral component 400 is sleeved on the inner tank 100. The spiral component 400 extends from the water inlet hole 110 to the water outlet hole 120 to form a spiral water channel 410 between the inner tank 100 and the thick film heating component 200.

[0053] In this embodiment, through the design of the spiral structure, not only is the flow distance of water during heating increased, the heating duration of the water flow is increased, but also the full contact between the water flow and the thick film heating component 200 is promoted, thereby improving the heat transfer efficiency.

[0054] In addition, the design of the spiral component 400 also takes into account the minimization of water flow resistance. Through fine flow channel design and smooth inner wall treatment, the water flow can smoothly pass through the spiral water channel 410, reducing energy loss and improving heating efficiency.

[0055] Optionally, the material of the spiral component 400 is plastic, silicone or metal.

[0056] In this embodiment, the material selection of the spiral component 400 has diversity and flexibility to meet the performance requirements in different application scenarios. If a plastic material is selected, such as high-temperature resistant polypropylene (PP) or polytetrafluoroethylene (PTFE), it can ensure good insulation performance and light weight, and at the same time, the cost is relatively low, which is suitable for automotive heater applications with strict requirements on weight and cost.

[0057] If a silicone material is selected, it can bring excellent high-temperature resistance, chemical corrosion resistance and softness, enabling the spiral component 400 to better adapt to the curvature change of the surface of the inner tank 100, reducing the installation difficulty and leakage risk. The elasticity of silicone can also absorb vibration and impact to a certain extent, improving the overall durability of the heater.

[0058] For applications that require higher heat conduction efficiency and stronger mechanical strength, metal materials such as stainless steel or aluminum alloy are ideal choices. The metal spiral component 400 can not only effectively transfer heat but also withstand high working pressures and temperature fluctuations, ensuring the stable operation of the heater under extreme conditions. At the same time, metal materials are easy to process and weld, facilitating the integration and installation with other components.

[0059] In addition, turbulators or enhanced heat transfer structures can be added inside or outside the spiral component 400. For example, tiny protrusions or grooves can be provided on the inner wall of the spiral water channel 410 to increase the turbulence of the water flow and promote convective heat transfer between the heat and the water flow; or heat sinks or heat pipes can be attached to the outer wall of the spiral component 400 to dissipate the heat generated by the thick film heating component 200 to the surrounding environment faster, improving the overall thermal efficiency.

[0060] Optionally, referring to Figure 5 , another embodiment of the present utility model provides a thick film heating device. Based on the above Figure 4 and Figure 5 shown embodiments, the spiral component 400 is detachably disposed on the inner tank 100.

[0061] In this embodiment, the detachable design of the spiral component 400 provides great convenience for the maintenance, cleaning, and personalized upgrade of the thick film heating device. Users or maintenance personnel can easily remove the spiral component 400 from the inner tank 100 for necessary cleaning or replacement without replacing the entire thick film heating device, greatly saving costs.

[0062] During the design, the spiral component 400 is nested on the outer wall of the inner tank 100 by an interference fit, or a special snap, threaded connection, or other quick locking mechanisms are used to achieve a firm connection with the inner tank 100. This detachable connection method not only simplifies the maintenance process but also allows users to replace the spiral component 400 with different lengths, diameters, or structures according to actual needs to adapt to different heating requirements and water flow rates.

[0063] The detachable spiral component 400 also allows users to make personalized customization according to actual needs. For example, in cold regions, users can choose a spiral component 400 with higher heat conduction efficiency and a larger heating area to improve the performance of the heater; while in warm regions, a more compact and lower energy consumption model can be selected to meet the requirements of energy conservation and environmental protection. This flexibility enables the thick film heating device of the present utility model to widely adapt to the diverse needs of different regions, different vehicle models, and different users.

[0064] In addition, in order to further improve the durability and safety of the heating device, a gasket or sealing ring can also be provided between the spiral assembly 400 and the inner tank 100 to prevent water from leaking into the heating assembly and causing short circuits or damage. The material of the gasket or sealing ring should have good high-temperature resistance, chemical corrosion resistance, and elastic recovery ability to ensure the reliability and stability of long-term use.

[0065] Optionally, referring to Figure 6 , another embodiment of the present utility model provides a thick-film heating device. Based on the above Figure 1 Furthermore Figure 2 shown embodiment, the water pumping assembly 300 includes a water pump 310, wherein:

[0066] The water pump 310 is arranged inside the inner tank 100. The water inlet end of the water pump 310 is used to connect to a water source, and the water outlet end of the water pump 310 is connected to the water inlet hole 110 through a pipeline 320. The water pump 310 is used to drive the water source to output water, and the water enters the water channel through the water inlet hole 110.

[0067] In this embodiment, the water pump 310, as the core component of the water pumping assembly 300, is designed and installed inside the inner tank 100 to minimize space occupation and optimize the water flow path. The water pump 310 is driven by a high-efficiency motor and can operate stably under the conditions of low noise and low power consumption, ensuring that the water source is stably and continuously pumped into the water channel. The water inlet end of the water pump 310 is directly connected to an external water source, such as a water tank or a water pipe. Through a well-sealed interface design, water leakage and air entry are effectively prevented, ensuring the purity of the water quality and the normal operation of the system.

[0068] In order to improve the water pumping efficiency of the water pump 310, a short and straight pipeline 320 is used to connect its water outlet end and the water inlet hole 110, reducing the water flow resistance and accelerating the water flow speed. This design enables the water flow to be more evenly distributed in the water channel, enhancing the heating effect.

[0069] Optionally, referring to Figure 7 , another embodiment of the present utility model provides a thick-film heating device. Based on any of the above Figures 1 to 6 shown embodiments, fixed baffles 130 are provided on both sides of the inner tank 100, and the fixed baffles 130 are used to support and fix the position of the inner tank 100.

[0070] In this embodiment, the design of the fixed baffles 130 enhances the structural stability and safety of the thick film heating device. These fixed baffles 130 are installed on both sides of the inner tank 100 and are made of high-strength materials such as stainless steel or aluminum alloy to withstand thermal stress and mechanical vibration that may be generated during the heating process. The fixed baffles 130 not only ensure the stable position of the inner tank 100 in the heating device, prevent displacement or shaking caused by water flow impact or temperature changes, but also provide additional support points to optimize the mechanical balance of the overall structure.

[0071] In addition, the fixed baffle 130 can also have a certain heat insulation function. Through the heat insulation material (such as ceramic coating or aerogel layer) coated on its surface, the heat exchange between the high temperature area inside the inner tank 100 and the external environment is effectively isolated, reducing energy loss and improving heating efficiency. This design is particularly suitable for application scenarios that require high efficiency and energy saving and compact space layout, such as car heaters or household instant water heaters.

[0072] In order to enhance the practicality and flexibility of the fixed baffle 130, the fixed baffle 130 can also be installed and adjusted in a variety of ways. For example, the fixed baffle 130 can be connected to the inner liner 100 and the thick film heating assembly 200 respectively through an adjustable bracket, and the user or maintenance personnel can adjust its position and angle according to actual needs to optimize the fixing effect and heating performance of the inner liner 100. At the same time, the fixed baffle 130 can also be designed as a modular structure, which is easy to replace and upgrade to adapt to different models and specifications of the inner liner 100.

[0073] Optionally, refer to Figure 8 and Figure 9 Another embodiment of the present invention provides a thick film heating device, based on the above Figures 1 to 6 In any of the illustrated embodiments, the thick film heating device further comprises a housing 500, a top cover 600 and a bottom plate 700, wherein:

[0074] The outer shell 500 is covered on the outer side of the inner tank 100 and the thick film heating component 200; the top cover 600 is arranged on the top of the outer shell 500 and is sealed and connected to the outer shell 500; the top cover 600 is provided with a pipeline through hole, and the pipeline through hole is used for the pipeline to pass through, so as to respectively connect the water outlet 120 and the pumping component 300; the bottom plate 700 is arranged at the bottom of the outer shell 500 and is sealed and connected to the outer shell 500.

[0075] In this embodiment, the combined design of the housing 500, the top cover 600, and the bottom plate 700 not only provides a solid protective shell for the thick film heating device, ensuring the integrity and safety of its internal components. The housing 500 is made of high-strength and corrosion-resistant materials such as ABS plastic or stainless steel, effectively resisting impacts, scratches, and chemical corrosion in the external environment and extending the service life of the product. The top cover 600, as a key component for connecting external pipes, its sealing performance is crucial. In this embodiment, the top cover 600 is tightly connected to the housing 500 through a silicone rubber sealing ring or a threaded sealing structure, ensuring no leakage around the pipe through-hole and guaranteeing that the water circulation and heat transfer inside the thick film heating device are not interfered by the outside world. At the same time, the pipe through-hole design on the top cover 600 is reasonable, facilitating users to install the inlet and outlet pipes according to actual needs, with high flexibility.

[0076] The bottom plate 700 bears the weight of the entire heating device. Its structure is stable and is connected to the bottom of the housing 500 through multiple fastening points, ensuring the stability of the thick film heating device during operation. Anti-slip pads or suction cups can also be provided on the bottom plate 700 to further enhance the fixing effect of the heating device in different installation environments and avoid accidents caused by movement or vibration.

[0077] To improve the user experience and maintenance convenience, a detachable connection structure can also be provided between the housing 500, the top cover 600, and the bottom plate 700. This design allows users to easily open the housing 500 when needed to inspect, clean, or replace the internal components. At the same time, the detachable structure also facilitates the upgrade and maintenance of the product, reducing the user's usage cost.

[0078] In addition, considering the special requirements of the heating device in different application scenarios, the housing 500, the top cover 600, and the bottom plate 700 can also be customized according to the specific environment. For example, in a humid or highly corrosive environment, materials with higher corrosion resistance can be selected; in occasions where high-temperature heating is required, the heat dissipation structure can be optimized to improve the heating efficiency. This flexibility enables the thick film heating device of the present utility model to be widely applicable to various complex and changeable environments and scenarios.

[0080] The circuit board 800 is disposed inside the housing 500 and is electrically connected to the thick film heating component 200. The circuit board 800 is used to control the heating power and heating time of the thick film heating component 200.

[0081] In this embodiment, the circuit board 800 serves as the control center of the thick-film heating device. It is embedded inside the housing 500, which not only saves space but also ensures the stability and safety of electrical connections. The circuit board 800 adopts advanced microprocessor technology and can accurately control the heating power and heating time of the thick-film heating component 200, realizing intelligent and efficient management of the heating tube 210.

[0082] To improve the user's convenience and safety in use, the circuit board 800 also integrates multiple protection mechanisms. These protection mechanisms include, but are not limited to, overcurrent protection, overheat protection, short-circuit protection, etc. They can respond quickly in case of abnormalities, cut off the power supply, and prevent safety accidents such as equipment damage and even fires. At the same time, the circuit board 800 also has a self-diagnosis function, which can monitor the working state of the device in real time. Once a fault or abnormality is detected, it can remind the user through indicators or displays, etc., for timely repair and handling.

[0083] In addition, the circuit board 800 can also support multiple heating modes, and users can select a suitable mode for heating according to actual needs. For example, in cases where rapid heating is required, the high-power mode can be selected; in cases where long-term heat preservation is required, the low-power mode can be selected to save energy. This diverse heating mode not only meets the personalized needs of different users but also improves the adaptability and flexibility of the device.

[0084] It can be understood that a control circuit for executing the control of the heating power and heating time of the thick-film heating component 200 can be provided on the circuit board 800. The control circuit can be implemented using a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), an SOC (System On Chip), etc.
