Description

Technical Field

[0001] The utility model relates to an environmentally friendly hot air circulation centrifugal fan, belonging to the technical field of centrifugal fans. Background Art

[0002] The hot air circulation centrifugal fan is an indispensable key component in the hot air circulation system. It mainly accelerates the gas and guides it to the desired direction through the rotating impeller to achieve the circulation and uniform distribution of the hot air. It is a ventilation, air exchange or air supply equipment designed and manufactured according to Euler's theorem and the law of conservation of mass. It is particularly suitable for occasions where hot air circulation is required. It uses the rotor kinetic energy to increase the gas pressure, or uses the inlet velocity kinetic energy to reduce the static pressure accordingly to achieve a certain air volume. In the hot air circulation system, the air source is the centrifugal fan that sends out hot air through the heater, and then through the air duct to the inner chamber of the oven. The used air is then sucked into the air duct to become a new air source for circulation until the set temperature value is reached.
