[0038] The working principle of a heat dissipation linear motor provided by the utility model is as follows:

The main air cooling component 10 blows air upward to assist in the heat dissipation, while reducing the temperature rise rate of the coolant in the liquid cooling component 9. The first auxiliary air cooling component 11 and the second auxiliary air cooling component 12 assist the main air cooling component 10 in dissipating heat to both sides, while accelerating the circulation of the airflow.
