[0022] Compared with the prior art, the utility model has the following beneficial technical effects:

[0023] By setting up the installation components for use with the mounting frame, for example, the fan may accumulate dust and dirt after long-term use, affecting the ventilation and heat dissipation effects. If the fan is not easy to disassemble, cleaning may become difficult, resulting in long-term accumulation of dust, affecting the experimental results and the life of the equipment. A fan that is easy to disassemble can be easily cleaned, maintained and replaced, thereby extending the service life of the fan and saving maintenance costs; and when maintenance or cleaning is required, the operator can perform the corresponding work more safely to avoid safety hazards caused by difficult maintenance operations.
