【Hybrid Fan】Boost the “power” of air-conditioned wear! Achieve rapid cooling with the Peltier fan

Due to the severe heat in recent years, the demand for air-conditioned fan clothing is increasing year by year. This summer is expected to be hot again. Let's take the level of “coolness” one step further with the innovative Peltier fan.

Patent structure "Reverse Fan" to solve heat dissipation problems

Normally, as the cooling surface of the Peltier element is lowered, the heating surface becomes hotter, and if the heat treatment is insufficient, the cooling efficiency decreases. Therefore, the Peltier fan "ZERO" employs a reverse fan based on the principles of aircraft propellers. It achieves a structure that blows air forward while exhausting heat to the rear at the same rotation speed.

Furthermore, through a design based on fluid dynamics, it efficiently draws in outside air to the center of the heat sink, allowing for both air blowing and heat dissipation within clothing to be handled by a single unit.

Comfortable cooling performance generated by a full aluminum plate and a quiet motor

The cooling plate is made of a full aluminum material with a diameter of 90mm and a thickness of 3mm. By using aluminum with high thermal conductivity, it enhances the cooling response upon contact while also suppressing discomfort caused by localized overcooling.

Equipped with a brushless motor utilizing Japanese technology, it significantly reduces operating noise and vibration. While ensuring powerful air volume, it achieves quietness suitable for comfortable use both indoors and outdoors.

High versatility taking advantage of handheld equipment and development background from the field

The design is compatible with existing air conditioning wear and commercially available mobile batteries, so there is no need to prepare new dedicated equipment. The ability to start using it immediately while keeping down installation costs is also a major attraction.

Incidentally, the origin of the development stemmed from the discomfort of seeing "even wearing air conditioning wear, one still gets wet with sweat" at actual work sites. As a new option to survive harsh summers, it will become a reassuring presence for many workers.
