| 摘要 |
The invention relates to a modular system for swirly driving and controlled orientability of hot air flows, which can be assembled lineary or matricial, depending on the application and location, designed to be used inside heating or cooking appliances, comprising a holder (1 ) on which is set at least one tube (2) which can be conical shaped; within each tube (2) is mounted a helical element (3) which may have variable pitch; a module consisting of a holder (1 ) with tubes (2) and helical elements (3) is installed inside a heating device known per se, so that the hot air flow inside the heating unit enters the holder (1 ) and passes through the tubes (2), and the helical elements (3) transforms the linear stream of hot air into eddy currents; the tubes (2) form with the holder (1 ) an angle (β) which determines the direction of hot air flows towards certain areas inside the heating or cooking appliance. |
