Description

Technical Field

[0001] The utility model relates to the technical field of cooling fans, and more specifically to a water curtain cooling fan. Background Art

[0002] The water curtain fan, also known as the evaporative cooling fan, is an evaporative cooling ventilation device that integrates cooling, ventilation, dust prevention and deodorization. It is mainly used in corporate workshops, public places and commercial entertainment venues. It can bring fresh air and cooling effect, and it is energy-saving and environmentally friendly. The core component of the water curtain fan is the evaporative wet curtain, which is usually composed of multiple layers of corrugated fiber laminate. This device does not require a compressor, refrigerant and copper pipes. Compared with traditional central air conditioners, the energy consumption of its main motor is only 1 / 8, which helps save electricity.

[0003] The existing utility model patent with patent application number CN202220873991.4 discloses a permanent magnet synchronous variable frequency adjustable speed evaporative water curtain cabinet cooling air unit, which is configured in the water curtain cabinet. The cooling air unit has a swingable and closable double-layer air outlet component configured in the front cabinet cavity of the water curtain cabinet, a permanent magnet synchronous variable frequency adjustable speed motor component and at least one water curtain component configured in the rear cabinet cavity of the water curtain cabinet. The permanent magnet synchronous variable frequency adjustable speed motor component of the patent fixes the permanent magnet synchronous variable frequency adjustable speed motor in the water curtain cabinet through a motor frame to form a cooling air unit. The permanent magnet synchronous variable frequency adjustable speed motor has high efficiency and is easy to adjust the speed by frequency conversion. There is no resistance loss in the rotor winding, and there is little or almost no reactive current in the stator winding, so that the temperature rise of the permanent magnet synchronous variable frequency adjustable speed motor is low, and the service life of the permanent magnet synchronous variable frequency adjustable speed motor is extended.

[0004] However, in this patent, it can be seen from the accompanying drawings that the air outlet component on the front of the fan unit is detachably connected to the front cabinet cavity with screws, which makes subsequent repairs and replacements and daily disassembly, cleaning and maintenance difficult and cumbersome, and requires unscrewing the screws one by one for disassembly.
