Принцип на работа и структура на вентилатора за промишлено охлаждане
The working principle of industry cooling fanis that DC cooling fan is a new mechatronic fan that uses the principle of electromagnetic induction and hall induction components as synchronous detection devices to control a group of circuits, switch the power on sequence of windings, generate rotating magnetic field and realize electronic commutation. It has obvious advantages in wide speed regulation range, controllability, reliability, light weight, environmental protection and energy saving, environmental tolerance and economy. It gradually replaces other types of motors in the field requiring high performance.
According to the rated voltage, industrial cooling fans can be divided into AC fans 110V, 220V, 380vdc and DC fans 5V, 12V, 24V and 48V. According to the flow direction of inlet and outlet air, the cooling fan can be divided into axial flow fan, centrifugal fan, mixed flow fan and cross flow fan.
Състав на вентилатора за промишлено охлаждане:
1. Rotor assembly: composed of fan blade plus shaft center plus magnetic strip plus motor housing.
2. Stator assembly: composed of silicon steel sheet plus wire frame plus pin plus enamelled wire plus PCB assembly plus outgoing line
3. Outer frame: shell plus bearing
The working principle of industrial cooling fan is realized according to energy conversion: electric energy to mechanical energy and then to kinetic energy,it is dissipated by forced thermal convection, and the heat is removed by heat exchange with the surrounding air by diversion, so as to realize the heat dissipation by forced convection.
