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 verification
Confirm 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 verification
Calculate 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.
