This application discloses a heat dissipation mechanism and a dental light curing machine. By installing a heat dissipation pipe inside the machine housing, an external gaseous or liquid heat exchange medium can enter the heat dissipation pipe through the mounting cavity and the inlet end under the action of a drive pump. When the heat exchange medium passes through the mounting cavity, it can carry away the heat generated by the light curing lamp, so the machine housing will not have a significant temperature rise, thus extending the service life of the equipment and preventing burns to patients. Then, when the heat exchange medium passes through the cooling module, the cooling module provides cooling to the heat dissipation pipe to reduce the temperature of the heat exchange medium.
