- Fin electric heating tube is an addition of metal fins (such as aluminum fins, copper fins, steel fins) on the basis of ordinary electric heating tubes, which improves heat exchange efficiency by expanding the heat dissipation area. It is particularly suitable for air/gas heating scenarios and has the characteristics of fast heating, precise temperature control, and flexible installation. Its application in the industrial field is highly focused on scenarios that require efficient heating of air or indirect heating of materials, which can be divided into the following categories:
- 1.Industrial drying/drying equipment: core used for material dehydration and solidificationIn industrial production, a large amount of materials (such as semi-finished and finished products) need to be dried with "hot air" to remove moisture or achieve solidification. Fin electric heating tubes become the core heating element of such equipment due to their ability to quickly heat air and achieve a thermal efficiency of over 90%.
Application scenarios Specific purposes Reasons for adaptation Plastic/rubber industry Drying of plastic pellets (to prevent the formation of bubbles during injection molding), drying of rubber products after vulcanization The heating temperature is controllable (50-150 ℃) and can be combined with a fan to form a hot air circulation, avoiding local overheating and deformation of the material Metal processing industry Dry metal parts before painting (remove surface oil/moisture), and dry hardware parts after electroplating Some scenes require corrosion resistance (optional 304/316 stainless steel fins), good uniformity of hot air, and guaranteed coating adhesion Textile/Printing and Dyeing Industry Drying of fabric and yarn (dehydration before shaping), drying after dye fixation Requires continuous and stable heating (24-hour operation), long service life of finned tubes (usually over 5000 hours), and low maintenance costs Wood/Paper Industry Drying of wood panels (to prevent cracking and deformation), drying of pulp/cardboard Can achieve high temperature heating (up to 200 ℃), wide coverage of hot air, suitable for large drying kilns Food/Pharmaceutical Industry Drying of food ingredients (such as grains, dehydrated vegetables), drying of pharmaceutical granules/capsules The material meets hygiene standards (304/316 stainless steel), with no pollutant release and a temperature control accuracy of ± 1 ℃, meeting GMP requirements
2.Industrial HVAC and Environmental Control: Maintaining Constant Temperature in Plants/Workshops
Industrial scenarios have strict requirements for environmental temperature and cleanliness (such as electronic workshops, precision assembly workshops, and clean rooms), and finned electric heating tubes are often used as the core heating components of air conditioning units and fresh air systems for winter heating or fresh air preheating.
1) Heating of industrial plants:
Suitable for large factories without centralized heating (such as mechanical workshops and storage factories), the hot air heating system is composed of "finned heating tubes+air duct fans", which can be temperature controlled by zones (such as separate temperature adjustment in equipment and operation areas), avoiding the problems of slow heating and pipeline freezing and cracking caused by traditional water heating.
In cold regions such as Northeast and Northwest, factories can also be used for "equipment preheating" (such as heating workshop air before starting in winter to prevent equipment from freezing due to low temperatures).
2) Cleanroom/Electronic Workshop Constant Temperature:
The production of electronic components (such as chips and circuit boards) requires constant temperature (20-25 ℃) and cleanliness. Fin electric heating tubes can be integrated into clean air conditioning systems, with no dust or odor during the heating process, and high temperature control accuracy (± 0.5 ℃) to avoid temperature fluctuations affecting component performance.
3) Heating in explosion-proof places:
Explosion proof workshops such as chemical, oil and gas, and coal mines can use "explosion-proof finned electric heating tubes" (with an explosion-proof aluminum alloy shell material and junction boxes that comply with Ex d IIB T4 standards) for air heating in hazardous environments to prevent safety accidents caused by electric sparks.
3.Pneumatic system and compressed air heating: ensuring stable operation of equipment
Industrial pneumatic equipment, such as cylinders and pneumatic valves, rely on dry compressed air to drive. If the compressed air contains moisture (which is prone to freezing at low temperatures), it can cause equipment failure. Fin electric heating tubes are mainly used for "compressed air heating and drying".
Working principle: Compressed air will release moisture after cooling, and it needs to be heated to 50-80 ℃ through a "finned heating tube" to reduce the relative humidity of the air. Then it enters a dryer for deep dehydration, and finally outputs dry compressed air.
Typical applications: automotive production lines (pneumatic robotic arms), machine tool processing (pneumatic fixtures), food packaging (pneumatic sealing machines), and other scenarios that rely on pneumatic systems.
4.Special industrial scenarios: customized heating needs
According to industry characteristics, finned electric heating tubes can be customized by material and structure to adapt to special environments
1) Corrosive environment:
Chemical and electroplating workshops need to heat air containing corrosive gases and use 316L stainless steel finned tubes (acid and alkali resistant) or titanium alloy finned tubes (strong corrosion resistant) to avoid oxidation and rusting of the fins.
2) Low temperature start-up heating:
Wind power equipment and outdoor control cabinets in cold regions need to heat the internal air before starting (to prevent component freezing), using a "small finned electric heating tube+temperature controller", which automatically starts at low temperatures and automatically stops when the temperature meets the standard.
3)Auxiliary heating of hot blast stove:
Small industrial hot air stoves (such as metal heat treatment and agricultural product drying) can use finned electric heating tubes as auxiliary heat sources to compensate for temperature fluctuations caused by gas/coal heating and achieve precise temperature control.
