Description

Technical Field

[0001] The present invention relates to the technical field of heat conversion, and particularly to an infrared heating curtain and its preparation process. Background Art

[0002] Currently, the existing heating technologies have the following problems when applied to human heating: 1. Low thermal efficiency: Traditional electric heaters, such as resistance wire heating devices and electric oil heaters, have large energy losses during the conversion of electrical energy into heat energy. When heating with resistance wires, a large amount of heat is dissipated into the surrounding environment through radiation and convection, resulting in limited heat actually used for heating and relatively low thermal efficiency.

[0003] 2. Uneven heating: Traditional heating devices (such as electric heaters) are difficult to achieve uniform heat distribution and easily form local high-temperature areas.

[0004] 3. Not environmentally friendly and noisy: Taking the diesel heater commonly used in trucks as an example, it generates heat by burning diesel for heating. This heating method not only produces a large amount of harmful gases, such as carbon monoxide and nitrogen oxides, which pollute the environment, but also has certain safety risks and does not meet the current requirements of environmental protection and sustainable development; at the same time, it uses a blower to transfer heat to the vehicle interior by convection, resulting in high noise.

[0005] 4. Inconvenient installation and storage: Traditional heating devices are usually large in size and complex in structure. The installation process is cumbersome and requires professional technicians to operate, increasing the installation cost and time cost.

[0023] Please refer to Figure 1, this embodiment provides an infrared heating curtain, which includes an infrared ray generating coating 1, a heating and temperature sensing layer 2, and a flexible substrate 3 arranged in sequence from top to bottom. The infrared ray generating coating 1 is made of an infrared ray generating material, which can efficiently convert the thermal energy generated by the heating and temperature sensing layer 2 into infrared radiation energy and emit it outward; through the way of infrared radiation, the heat is directly transmitted to the atmosphere or the surface of the receiving object. Compared with the ordinary heating method that can only conduct slowly through the air, the heating efficiency of the space is greatly improved, and the heating efficiency of the space is increased by more than 60%. The heating and temperature sensing layer 2 is made of a heating material with a high resistivity and a temperature sensing material whose impedance changes linearly with the change of temperature. It can not only effectively convert the electrical energy provided by the power supply into thermal energy through the heating material to provide the heat source required by the infrared heating curtain, but also can monitor the heating temperature information of the heating material in real time and accurately through the temperature sensing material. At the same time, integrating the heating and temperature sensing functions into one layer can greatly reduce the overall thickness of the infrared heating curtain, and the overall thickness can be reduced to 2 mm. The flexible substrate 3 is made of a flexible material into a thin film sheet structure, so that it can be conveniently applied to corners or curved surfaces, can better fit the complex shape of the object to be heated, realize uniform heating in all directions, and avoid the problem that it is difficult for traditional heating devices to cover special parts; moreover, it can be rolled up for storage, greatly saving storage space, facilitating transportation and storage, and solving the problems of large volume and difficult storage of traditional heating devices. In addition, the infrared heating curtain has the characteristics of fast heating and good heat conduction performance, with a rapid surface heat transfer speed, a faster heating speed, and uniform heating, effectively avoiding the formation of local high-temperature areas in the object to be heated, and at the same time reducing the occurrence probability of serious safety hazards such as thermal runaway.

[0024] The infrared heating curtain of this embodiment can be applied to vacuum or closed spaces, and this characteristic enables it to completely break through the limitation that traditional heating technologies need to rely on heat conduction media (such as air, water or other liquid and solid media) to transfer heat. In a vacuum environment, since there is no conventional heat conduction medium such as air, the traditional conduction and convection heat transfer methods are almost impossible to achieve. However, this heating device uses the infrared ray generating coating 1 to convert the thermal energy generated by the heating and temperature sensing layer 2 into infrared radiation energy, and directly transfers the heat to the surface of the target object in a radiation manner, realizing effective heating in the absence of a heat conduction medium. In a closed space, even if the air fluidity is poor and the traditional heating method is prone to uneven heat distribution, the infrared radiation heating method of this infrared heating curtain can also quickly and evenly heat the objects in the space, avoiding local overheating or overcooling. This unique advantage enables this infrared heating curtain to be applied not only to human heating, but also to fields with special requirements for vacuum or closed environments such as aerospace, vacuum coating, and semiconductor manufacturing.

[0025] In one embodiment, the infrared generating material is not limited to any one of nanomaterials, graphene, carbon nanotube composites, and graphene-boron nitride composites. Suitable infrared generating materials can be selected according to different application scenarios, performance requirements, and costs, enabling the infrared heating curtain to better adapt to different usage environments and heating requirements and improving the performance adaptability of the product. Different infrared generating materials have their own unique performance characteristics. For example, nanomaterials have a higher specific surface area and stronger infrared radiation ability, and can convert thermal energy into infrared radiation energy more efficiently; graphene has excellent thermal conductivity and electrical properties, which helps to improve the heat conduction and energy conversion efficiency of the infrared generating coating 1; carbon nanotube composites and graphene-boron nitride composites combine the advantages of multiple materials and exhibit better comprehensive performance under specific conditions.

[0026] In one embodiment, the heating material is not limited to any one of heating wires, ceramics, carbon powder metal mixtures, and metal oxides, enabling the infrared heating curtain to select suitable heating materials according to different requirements such as heating power, heating speed, and heating stability. For example, heating wires have a relatively high resistivity and good flexibility, and are suitable for occasions that require a relatively high heating power and a certain degree of flexibility; ceramic heating materials have the advantages of high temperature resistance and corrosion resistance, and are suitable for heating in high-temperature environments; carbon powder metal mixtures and metal oxides have unique electrical and thermal properties and can be adjusted and optimized according to specific requirements.

[0027] In one embodiment, the temperature sensing material is PTC thermistor powder or NTC thermistor powder. The impedance of the thermistor powder has a positive temperature coefficient characteristic, that is, its resistance value increases sharply with the increase of temperature. At the same time, the impedance performance of the thermistor powder is stable, has good repeatability and consistency within a certain temperature range, and can work reliably for a long time, thereby improving the stability and reliability of the entire infrared heating curtain. Of course, the temperature sensing material can also be bismuth telluride (Bi2Te3), lead telluride (PbTe), silicon germanium (SiGe) alloy, bimetallic material, temperature-sensitive polymer material, etc. The present invention does not limit this. For example, thermoelectric materials such as bismuth telluride and lead telluride have relatively high thermoelectric performance and are suitable for some high-precision temperature monitoring occasions that are sensitive to temperature; bimetallic materials have the advantages of simplicity and low cost and are suitable for some occasions where the accuracy requirements are not particularly high.

[0028] Please refer to Figure 2, in one embodiment, the heating and temperature sensing layer 2 includes a heating element 21 formed of a heating material and a temperature sensing element 22 formed of a temperature sensing material, and the temperature sensing element 22 is disposed adjacent to the heating element 21. The temperature sensing element 22 being disposed adjacent to the heating element 21 enables the temperature sensing element 22 to more accurately and timely sense the temperature change of the heating element 21. At the same time, separating and adjacently arranging the heating element 21 and the temperature sensing element 22 makes the structure of the heating and temperature sensing layer 2 clearer and more reasonable, which is conducive to process control during the manufacturing process, facilitates separate processing and debugging of the heating element 21 and the temperature sensing element 22, and improves production efficiency and product quality.

[0029] Please refer to Figure 2 , further, one end of the heating element 21 is connected to a first positive electrode 211, the other end of the heating element 21 is connected to a first negative electrode 212, one end of the temperature sensing element 22 is connected to a second positive electrode 221, and the other end of the temperature sensing element 22 is connected to a second negative electrode 222. By respectively connecting independent positive and negative electrodes to the heating element 21 and the temperature sensing element 22, it ensures that they can obtain stable power supply and signal transmission, and makes the connection between the heating element 21 and the temperature sensing element 22 and the external circuit more convenient and standardized. When designing and installing the control circuit of the infrared heating curtain, the heating element 21 and the temperature sensing element 22 can be easily connected to the circuit according to the connection method of the electrodes, and corresponding control and adjustment can be performed.

[0030] In one embodiment, the material of the flexible substrate 3 is not limited to any one of soft silicone, fiber, resin, fabric, etc. The material of the flexible substrate 3 can be independently selected according to the different heating temperatures of the heating and temperature sensing layer 2, which ensures that the flexible substrate 3 can work stably at the corresponding heating temperature and guarantees the reliability of the infrared heating curtain. For example, for the case of higher heating temperature, selecting soft silicone, high-temperature resistant flexible resin or flexible fiber material that can withstand high temperature can avoid problems such as deformation and damage of the flexible substrate 3 at high temperature, thereby ensuring the normal operation of the entire infrared heating curtain, and further guaranteeing the performance and safety of the heating device. For the case of lower heating temperature, such as 45° for human body warming, ordinary fabric material can be selected to reduce production costs.

[0031] Please refer to Figure 3 , the present invention provides a preparation process of an infrared heating curtain as described in any of the above embodiments, including the following steps: Step S1, manufacturing the flexible substrate 3, which provides a stable support basis for the subsequent heating and temperature sensing layer 2 and the infrared emitting coating 1; Step S2, uniformly printing the heating material and the temperature sensing material on the surface of the flexible substrate 3 to form the heating and temperature sensing layer 2, realizing the integration of the heating and temperature sensing functions in one layer; Step S3: Spray an infrared ray generating material on the surface of the flexible substrate 3 with the heat generating and temperature sensing layer 2 to form an infrared ray generating coating 1.

[0032] For the preparation process of the above infrared heating curtain, by successively manufacturing the flexible substrate 3, forming the heat generating and temperature sensing layer 2, and spraying the infrared ray generating coating 1, each key part of the infrared heating curtain is constructed in an orderly manner, ensuring the complete realization of functions from the basic layer support to heat generation, temperature sensing, and infrared radiation. Moreover, each step is closely connected. This not only enables the final product to have good structural stability and functional integrity, effectively converting electrical energy into heat energy and efficiently transferring heat in the form of infrared radiation, but also can greatly reduce the overall thickness of the infrared heating curtain, reducing the overall thickness to 2 mm.

[0033] In one embodiment, step S2 specifically includes the following sub-steps: Step S21: Prepare a heat generating material slurry and a temperature sensing material slurry; specifically, by pre-treating (such as grinding, dispersing, etc.) the heat generating material and the temperature sensing material and mixing them with other components (such as binders, solvents, additives, etc.) to prepare a slurry, the fluidity, dispersibility, and adhesiveness of the materials can be improved, which helps the materials to be more evenly distributed on the surface of the flexible substrate 3 during the printing process, and improves the performance stability and consistency of the heat generating and temperature sensing layer 2.

[0034] Step S22: Pour the heat generating material slurry and the temperature sensing material slurry into the corresponding material tanks of the printing equipment respectively, which is convenient for independent control and adjustment of the printing amount and printing process of each material, and precisely controls the distribution and thickness of the heat generating material and the temperature sensing material on the flexible substrate 3 according to the design requirements, so as to achieve precise regulation of the performance of the heat generating and temperature sensing layer 2.

[0035] Step S23: The printing equipment prints on the surface of the flexible substrate 3 according to the pre-designed pattern and layout, and makes the printed heat generating material and temperature sensing material adjacent to each other, ensuring that the temperature sensor 22 can timely and accurately sense the temperature change of the heating element 21, and improving the accuracy and response speed of temperature monitoring; Step S24: After printing, perform a drying and curing treatment on the flexible substrate 3 with the heat generating material and the temperature sensing material to remove the solvent in the slurry, form a firm bond between the heat generating material and the temperature sensing material and the flexible substrate 3, enhance the bonding force between layers, thereby improving the stability of the heat generating and temperature sensing layer 2 and preventing the phenomenon of material shedding or delamination during use.

[0036] The above steps S21 - S23 form the heating and temperature sensing layer 2 by printing. First, by printing according to a pre - designed pattern and layout, the heating material and the temperature sensing material can be accurately placed at the designated positions on the flexible substrate 3, realizing a reasonable layout of the heating body 21 and the temperature sensing body 22. For example, the temperature sensing body 22 can be accurately arranged adjacent to the heating body 21 to ensure that the temperature sensing body 22 can timely and accurately sense the temperature change of the heating body 21, providing a basis for precise temperature control and realizing the precise integration of the heating and temperature sensing functions. Second, the printing process can evenly distribute the heating material slurry and the temperature sensing material slurry on the surface of the flexible substrate 3, ensuring the uniformity and consistency of the heating and temperature sensing layer 2, which helps to improve the performance stability of the heating and temperature sensing layer 2, avoiding the situations of uneven local heating or inaccurate temperature sensing, and thus enhancing the performance of the entire infrared heating curtain. Third, when preparing the printing slurry, the formulations of the heating material and the temperature sensing material can be adjusted and optimized. For example, the heating power can be adjusted by changing the resistivity and content of the heating material, and different types of temperature sensing materials can be selected to change the temperature sensing range and accuracy, etc. At the same time, during the printing process, the performance of the heating and temperature sensing layer 2 can be further regulated by controlling the printing parameters (such as printing pressure, speed, etc.) to meet different application requirements. Fourth, compared with other processing methods, the printing process has a high production efficiency, can complete the production of the heating and temperature sensing layer 2 in a short time, is conducive to improving the production speed of the infrared heating curtain, reducing the production cost, and meeting the needs of large - scale production. At the same time, the printing process is relatively simple, and the required equipment and material costs are relatively low. At the same time, by precisely controlling the usage amount of materials, material waste can be reduced, further lowering the production cost and achieving better cost - effectiveness.

[0037] In one embodiment, step S3 specifically includes the following sub - steps: Step S31: Prepare the spraying liquid of the infrared - ray generating material. Specifically, by pretreating (such as dispersing, purifying, etc.) the infrared - ray generating material and mixing it with other components (such as solvents, binders, etc.) to prepare the spraying liquid, the properties such as the dispersibility, fluidity, and adhesiveness of the material can be improved, so that the material can be more evenly distributed on the surface of the heating and temperature sensing layer 2 during the spraying process, improving the performance stability and consistency of the infrared - ray generating coating 1. Step S32: Pour the prepared spraying liquid of the infrared - ray generating material into the material tank of the spraying equipment, providing a stable material supply for the spraying process and ensuring the continuity of the spraying operation. Step S33: The spraying device evenly sprays the infrared ray generating material spraying liquid on the surface of the flexible substrate 3 with the heat generating and temperature sensing layer 2, and performs drying and curing treatment, thereby forming an infrared ray generating coating 1 with a uniform thickness. Among them, the uniform coating helps to improve the uniformity and efficiency of infrared radiation, ensuring that the infrared heating curtain can evenly radiate heat to the surrounding space during use. The drying and curing treatment can form a firm bond between the infrared ray generating material, the heat generating and temperature sensing layer 2, and the flexible substrate 3, enhancing the adhesion and stability of the coating. At the same time, the drying and curing process can also make the performance of the coating more stable, such as improving its infrared radiation performance and weather resistance, etc., and extending the service life of the infrared heating curtain.

[0038] The above steps S31 - S33 form the infrared ray generating coating 1 by spraying. On the one hand, the spraying device can evenly spray the infrared ray generating material spraying liquid on the surface of the flexible substrate 3 with the heat generating and temperature sensing layer 2, forming an infrared ray generating coating 1 with a uniform thickness and good quality, thereby improving the uniformity and efficiency of infrared radiation, ensuring that the infrared heating curtain can evenly radiate heat to the surrounding space, and thus improving the heating effect on the space. On the other hand, the spraying process can better adapt to the complex surface shape of the flexible substrate 3 with the heat generating and temperature sensing layer 2, and can evenly spray the infrared ray generating material at corners, curved surfaces and other parts to form a complete coating, which is very important for achieving uniform heating in all directions of the infrared heating curtain, avoiding the problem of poor local heating effect caused by uneven coating. On the third hand, according to the characteristics and requirements of different infrared ray generating materials, appropriate spraying methods (such as air spraying, high-pressure airless spraying, electrostatic spraying, etc.) and spraying parameters (such as spraying pressure, flow rate, atomization effect, etc.) can be selected, so that various infrared ray generating materials can be better applied to coating preparation, providing convenience for selecting different performance infrared ray generating materials, being conducive to optimizing the performance of the infrared ray generating coating 1, and meeting the requirements of infrared radiation performance in different application scenarios. On the fourth hand, the spraying process is convenient for realizing continuous production, can quickly prepare coatings for multiple products on the production line, improve production efficiency, and meet the needs of large-scale production. At the same time, through automated spraying equipment and control systems, the spraying process can be precisely controlled to ensure the consistency of coating quality.
