Cooling fans are divided into refrigeration industrial cooling fans and domestic cooling fans. Industrial cooling fans are generally used in cold storage and cold chain logistics refrigeration environments. Household cooling fans are also called water-cooled air conditioners. They are a kind of cooling, ventilation, dustproof and deodorizing. Evaporative cooling and ventilation unit.

In addition to allowing fresh air and lowering temperatures in enterprise workshops, public places, commercial and entertainment venues, the air cooler has an important feature---energy saving and environmental protection! It is a new environmentally friendly product with no compressor, no refrigerant and no copper tube. The main component core----evaporative wet curtain (multi-layer corrugated fiber laminate) and 1.1KW main motor / is traditional The air conditioner consumes 1/8 of electricity, which can save more electricity for various industries.

The electric fan is referred to as an electric fan, also called a fan and a fan fan. It is a household appliance that uses a motor to drive the rotation of the fan blade to accelerate the circulation of air. It is mainly used for cooling off the heat and circulating air. Widely used in homes, classrooms, shops, hospitals and hotels. The fan is mainly composed of a fan head, a blade, a mesh cover and a control device.

The fan head includes an electric motor, front and rear end covers, and a moving air supply mechanism. The main components of the electric fan are: AC motors. The working principle is that the energized coil is rotated by the force in the magnetic field. Electrical energy is converted into mechanical energy, and at the same time, due to the coil resistance, it is inevitable that some of the electrical energy is converted into thermal energy. A common household fan is essentially an axial fan, ie the flow of wind is parallel to the axis of rotation of the blade.
