Machine Design Highlights
The internal airflow path of the air outlet accumulates heat, which is conducted to the surface through the housing, creating a risk of burns. Due to the extremely compact internal space, traditional insulation materials cannot effectively block this heat conduction. Therefore, an active cooling system has been designed: its air outlet (two small holes) directs about 5% of the cold air not into the heating element, but through the interlayer of the housing. This flowing cold air forms an active air-cooled insulation layer between the inner and outer shells, preventing internal heat from transferring to the surface. It is precisely this ingenious system that makes the slim body possible.
The triangular cross-section of the body is adopted not just for aesthetics, but for practical reasons. Since the straightening dryer is often used blindly by feel, a round body gives no clue to the nozzle’s orientation—yet that orientation decides whether hair is pulled perfectly straight or given an inward curl. The triangle matches the hand’s natural grip, letting users pinpoint the airflow direction with a light touch, making control both intuitive and efficient.
The hair-straightening dryer generates a high-speed jet through a narrow slit, creating a low-pressure zone according to Bernoulli’s principle. Air at the slit’s outer edge, being at higher pressure, is drawn inward; this airflow exerts a pulling force on the hair, guiding it into the slit. The critical design point is to keep the airflow velocity inside the slit high enough to produce stronger suction and ensure smooth hair attraction.
The key to rapid drying lies in the precise pairing of temperature and airflow: only when the two work together can the “golden drying zone” of high-efficiency evaporation be created. Traditional dryers must be kept in constant motion, so most of the heat and airflow is lost in transit. To compensate, manufacturers are forced to raise the temperature. By locking the hair at an exact, fixed distance from the nozzle, we can build a “safe drying core” where the temperature stays constant and the airflow stays fast. Here the temperature never exceeds the damage-proof threshold, while ultra-high-speed airflow is applied 100 % to evaporating water, eliminating waste. This is the essence of the straightening dryer: every strand is held continuously at the optimal balance point of temperature and airflow.
