Shengzhou Chuaili Environmental Technology Co., Ltd.'s Fin heating tube (finned heating tube) is an efficient electric heating element specifically designed for cooling and heating scenarios. It has outstanding core advantages.
Product Core CharacteristicsStructural Design:
Metal heat dissipation fins are wound around the surface of the ordinary heating element, increasing the heat dissipation area by 2 to 3 times compared to the ordinary heating tube, and the allowable surface power load can reach 3 to 4 times that of the ordinary element.
Performance Characteristics:
Under the same power conditions, it has the characteristics of fast heating, uniform heating, good heat dissipation performance, and high thermal efficiency. After the overall length of the element is shortened, the heat loss of the element itself is significantly reduced.
Usage Advantages:
The product has a long service life, the accompanying heating device has a smaller volume, and the overall cost is lower. At the same time, a reasonable structural design has been made according to the installation scenario, making on-site installation convenient.
Enterprise Supporting CapacityAs a professional manufacturer specializing in refrigeration and electric heating elements in Shengzhou, Chuaili Environment can provide a fully customized Fin heating tube solution for different equipment needs, suitable for various scenarios such as cooling fan defrosting and industrial dry heating.The enterprise has an annual production capacity of 2 million sets of electric heating elements and is equipped with 10 or more professional R&D personnel, which can provide stable long-term supply support.
Complete technical parametersCore structural parameters: The heat dissipation area is expanded by 2 to 3 times compared to ordinary light tubes, and the surface power load reaches 3 to 4 times that of ordinary heating tubes. The thermal efficiency is improved by more than 30% compared to traditional products.
Material configuration:
304/316L high-grade stainless steel is used as the tube body base material, combined with high-flame-retardant silicone rubber wires, sealing heads, and magnesium oxide powder treated with high-grade silicone oil, with high insulation resistance and low moisture absorption.Performance indicators: The continuous working life can reach more than 8,000 hours. It supports fully customized tube diameters, lengths, and fin density adjustments, and is suitable for the installation space requirements of different devices.
Customized forms:
Various forms such as I-type, U-type, and W-type can be provided, suitable for different ducts and cabinet installation scenarios.
Applicable scenarios listRefrigeration and cold chain core scenarios: Evaporator defrosting of cold storage fans, frost-free refrigerators, auxiliary heating for refrigeration display cabinets/kitchen refrigerators, ocean-going refrigerated containers, refrigeration systems for refrigerated transportation vehicles.
Industrial dry heating scenarios:
Industrial ovens, dryers, hot air circulation drying rooms, paint baking rooms, air heating for power high and low voltage switch cabinets, terminal boxes, moisture-proof and dehumidification.Other extended scenarios: Frosting of food processing equipment, commercial air conditioning system auxiliary heating, plastic machinery, chemical reaction vessels, and auxiliary heating for supporting equipment.
Condition verificationConfirm that the heating medium is air/dry gas/weakly corrosive gas. It is prohibited from being directly used in scenarios with strong corrosive liquids. It matches the core positioning of the Chuanli products that focus on air convection heating.
Verify the maximum working temperature:
The regular model is suitable for ≤300℃ conditions, and the high-temperature customized model can cover ≤450℃ scenarios. Choose 304/316L stainless steel or upgrade to high-temperature resistant alloy materials as needed.
Measure the reserved pipe diameter, length, and installation hole positions to avoid interference with the internal structure of the equipment, and adapt to customized shapes such as I-type/U-type/W-type.
Power and load verificationCalculate the total heating power based on the heat load formula and reserve 20% margin to avoid long-term full-load operation. The power of a single pipe of Chuanli products covers 50W~20KW, and multiple pipes can be combined to match the total demand.
Verify the surface power density: In natural convection scenarios, it is controlled at ≤1.5W/cm², and in forced convection scenarios, ≤2.5W/cm². With the diffusion heat area of the fins being 2-3 times larger, dry burning overheating risks are eliminated.Material compatibility verification: The pipe body base material: in normal temperature dry scenarios, select 304 stainless steel; in humid/weakly corrosive scenarios, upgrade to 316L stainless steel; for special high-temperature scenarios, select Incoloy alloy. The entire series refuses carbon steel materials prone to rust.Fin material: In regular scenarios, select stainless steel fins; for low-cost scenarios ≤200℃, select aluminum fins to ensure the material matching between the fins and the pipe body and avoid electrochemical corrosion.
Internal filler material:
Confirm the use of modified high-temperature silicon oil treated with magnesium oxide powder, with an insulation grade of ≥B level. Long-term use does not absorb moisture and the insulation performance does not deteriorate.
Structure and installation verification
Fin parameters:
In dusty environments, the fin spacing should be ≥8mm to avoid dust accumulation and blockage. In regular scenarios, it is controlled at 6~10mm. Select spiral wave-shaped fins, and the heat exchange efficiency is improved by 30% compared to flat fins.
Installation method:
Confirm the thread specification (such as G1/2, M24×1.5) or flange standard. Support various interfaces such as threads, flanges, and brackets, and directly adapt on-site without modification.
Electrical parameters:
Confirm the working voltage matches 12V~660V, the wire's temperature resistance grade is ≥180℃, and standard configuration high-resistance flame-retardant silicone wire is provided， suitable for different electronic control systems.Safety and lifespan verification
Protection level：
In regular scenarios， it meets IP44. For cold storage defrosting scenarios with high humidity， upgrade to IP65 waterproof sealing structure， suitable for high-humidity environments.
Companion protection：
Select protection elements such as built-in thermocouples， over-temperature fuse wires as needed， and link with the temperature control system to eliminate the risk of dry burning and fire.
Expected lifespan：
In regular scenarios， the continuous operation lifespan is ≥8000 hours. The product passes full-condition aging tests and the long-term operation failure rate is much lower than the industry average.
Shengzhou Chuanli Environment + Zhejiang Jixite Dodo Comprehensive Export and Foreign Trade Analysis (semi-hermetic piston refrigeration compressors, industrial refrigeration units)
Business positioning: Jixite Dodo focuses on semi-hermetic piston refrigeration compressors (R404A/R134a/R507A/R23/R32 environmentally friendly refrigerants, -60℃ deep cold, cold storage/quick freezing/food freezing); Chuanli Environment provides industrial refrigeration complete sets of units, cooling systems, condensers, evaporators, cold storage refrigeration integration solutions, belonging to the core refrigeration main unit + complete system export, HS code core: 841861, 841869 (refrigeration units, compressors), the following is a complete dissection based on customs export data, overseas markets, keywords, customer profiles, competitors, online promotion.
The export of industrial refrigeration compressors/cold storage units in China is stable overall. Southeast Asia is the largest market (accounting for about 35% of domestic similar exports), followed by the Middle East, Central Asia, Russia, South America, Africa. Europe belongs to the high-end market, with high entry barriers (CE, PED, refrigerant environmental protection regulations).
Southeast Asia: Indonesia, Malaysia, Vietnam, Thailand, Philippines (small and medium-sized cold storages, aquatic products, food processing plants, large volume, cost priority)
Middle East: Saudi Arabia, United Arab Emirates, Qatar (high-temperature conditions, cold storage, cold chain warehousing, sufficient budget)
Central Asia/Russia: Kazakhstan, Uzbekistan, Russia (low-temperature cold storages, meat freezing, strong demand for low-temperature models)
Latin America: Chile, Peru (aquatic cold chain, recent import growth rate high)
