Abstract
An improved thermal fogging device includes an extended heat transfer surface located within the aerosolization chamber that increases the mixing of the liquid chemical particles and the hot gases in the aerosol to improve aerosolization. The extended heat transfer surface also helps to increase the heat transfer to the forming aerosol in the aerosolization chamber.
Claims14
A thermal fogger for creating stable aerosols from a liquid material, comprising:
- a heating chamber;
- and
- an elongated aerosolization chamber in communication with the heating chamber, the elongated aerosolization chamber comprising:
- an introduction port defined in a proximal end of the elongated aerosolization chamber;
- an extended-surface element disposed longitudinally within the elongated aerosolization chamber, the extended-surface element comprising a convoluted surface;
- and
- an outlet opening defined at a distal end of the elongated aerosolization chamber,
- wherein the extended-surface element further comprises:
- flow diversion blades defining the convoluted surface, the flow diversion blades having a substantially uniform maximum diameter about equal to an inner diameter of the elongated aerosolization chamber.
