Electrical Thermal oil heater, with their advantages of high efficiency and energy saving, precise temperature control, safety, and environmental friendliness, have been widely applied in multiple emerging industries. In particular, they have demonstrated great potential in fields such as new energy, new materials, and biomedicine.
1. New energy industry
Solar photovoltaic industry: In the production process of silicon wafers, from raw material purification to cell wafer molding, precise temperature control is required in multiple process steps. Electric heating heat transfer oil furnaces can provide a temperature control accuracy of ±1℃, ensuring uniform heating of silicon wafers during key processes such as high-temperature diffusion and annealing, and guaranteeing photoelectric conversion efficiency and quality stability. Lithium battery manufacturing: In the production of lithium battery separators and high-temperature processing of battery materials, a precisely controlled temperature environment is required. Electric heating heat transfer oil furnaces can provide a constant heat source, assisting in key steps such as material modification and new material synthesis, ensuring the consistency and stability of battery performance. Wind power equipment manufacturing: The molding of large wind turbine blades requires the use of molds for the infusion process, and maintaining the molds within a suitable curing temperature range is crucial. Heat transfer oil furnaces, through their efficient heat transfer performance, evenly distribute heat to all parts of the molds, coupled with an automated control system for real-time monitoring and temperature adjustment, enhancing the strength and reliability of the blades.
II. New material industry
Carbon fiber manufacturing: During the hot pressing process of carbon fiber prepreg, the heat transfer oil furnace provides a uniform and stable heat source for the autoclave, ensuring that the resin is fully cured under high temperature and high pressure, thereby enhancing the mechanical properties of the composite material. In the carbonization (1000-1600°C) and graphitization (2000-3000°C) stages, the heat transfer oil furnace is combined with electric heating or gas heating systems to achieve precise temperature control. Composite material molding: In the molding process of composite materials such as glass fiber and aramid fiber, the heat transfer oil furnace ensures a temperature difference of less than 5°C between the inside and outside of the material during the curing process through the mold heating system, eliminating defects such as warping and cracking. In the Resin Transfer Molding (RTM) process, it provides a heat source for preheating the mold before resin injection, shortening the curing cycle. Nanomaterial synthesis: In the synthesis of nanoparticles (such as quantum dots and nanowires), the heat transfer oil furnaceprovides a constant temperature environment of 100-300°C for the reaction vessel, ensuring consistent reaction conditions and achieving uniform growth and size control of the nanoparticles. In the spray drying process, it is combined with a hot air circulation system to prevent nanoparticle agglomeration and maintain the dispersibility of the material.
III. Biomedical industry
Pharmaceutical production: In the processes of active pharmaceutical ingredient (API) synthesis, traditional Chinese medicine extraction, and formulation drying, electrically heated heat-conducting oil furnaces demonstrate their irreplaceable value. Their cleanliness throughout the entire process meets the high cleanliness standards of the pharmaceutical environment, without any combustion by-products, ensuring the purity of the drugs. Stable temperature control accuracy (up to ±0.5℃) is crucial for many biochemical synthesis reactions that are extremely sensitive to temperature. It can PID control the reaction rate and direction to ±1℃, improving the yield and purity of the API. Enzyme catalysis reaction: In the scenario of enzyme catalysis reactions in the field of biomedicine, by establishing a temperature-reaction rate mathematical model, a segmented temperature control strategy with an accuracy of 0.1℃ can be achieved, ensuring that key reaction steps are completed within the golden temperature window. After applying this technology, a vaccine production enterprise increased the yield of the target product by 8.7% while reducing annual energy consumption by 12%.
IV. Electronics industry
LED chip manufacturing: In MOCVD (Metal Organic Chemical Vapor Deposition) equipment, a heat-conducting oil furnace heats the substrate to 600-800℃, ensuring uniform growth of the epitaxial layer. Solar cells: It provides heat sources for diffusion furnaces, coating machines, and other equipment, optimizing the photoelectric conversion efficiency of the cells.
V. Other emerging applications
Thermal management of new energy vehicles: Although direct use of heat transfer oil heaters is rare, their technical principles are applied in the design of battery heating systems to ensure that batteries can operate normally under extreme temperatures. Defense research: Primarily used as high-temperature heat sources for the development of new technologies, materials, and products in defense research. The application of electrically heated heat transfer oil furnaces in these emerging industries not only enhances production efficiency and product quality but also, through their energy-saving and environmentally friendly characteristics, assists enterprises in achieving green, low-carbon, and sustainable development goals. With continuous technological advancements, their application prospects will become even broader.
