How much space is needed for heat dissipation when the Air Fryer is running?

As a star product in modern kitchens, the safety specifications of air fryers are often ignored. According to the 2023 survey report of the National Technical Committee for Standardization of Household Appliances, 38% of consumers have insufficient heat dissipation space when using air fryers.

1. Engineering principles of heat dissipation system
The air fryer adopts thermodynamic eddy current circulation technology, and the internal temperature can reach 200℃ when working. Its cooling system includes a triple protection mechanism:
Rear centrifugal fan: responsible for forced convection cooling, the speed can reach 2000 rpm
Top radiation heat sink: heat conduction through the surface black body radiation principle
Bottom convection pores: use natural convection to form a cooling channel
II. Actual measurement of the relationship between space parameters and performance
Laboratory test data shows:
Reserved space Working temperature Power consumption Noise value Life impact
5cm +12% +18% +6dB -30%
10cm +5% +8% +3dB -15%
15cm Benchmark value Benchmark value Benchmark value No impact
III. Safety distance calculation formula
Minimum safety distance = √(rated power/100) × 2.54 cm
Take the 1500W model as an example:
√(1500/100)=3.87 → 3.87×2.54≈10cm
It is recommended to keep more than 15cm of three-dimensional space in actual use, with special attention to:
The rear heat dissipation port needs to maintain a clearance of 20cm
It is forbidden to place it on a wooden desktop for direct use (it should be equipped with a stone insulation pad of more than 5mm)
Maintain a semi-open angle with the wall (30-45 degrees is recommended)
IV. Thermal imaging monitoring warning
The infrared thermal imager shows that when the side space is less than 8cm:
The surface temperature rises from the safe value of 65℃ to 82℃
A hot spot of 120℃ appears in the circuit board area
Plastic parts accelerate aging, and the risk of releasing VOC increases by 3 times
V. Space optimization plan
Small kitchen users can use:
Telescopic bracket (load bearing ≥8kg)
High temperature resistant silicone pad (temperature resistance above 250℃)
Vertical heat dissipation system (professional modification required)
Regularly check the dust accumulation at the heat dissipation port, and it is recommended to clean the heat dissipation channel with compressed air (pressure ≤0.3MPa) every month. If abnormal noise (over 65dB) or shell deformation is found, it should be stopped immediately.
