Abstract

L'invention concerne un tuyau d'extension d'échappement et une soufflante utilisant celui-ci. Le tuyau d'extension d'échappement comprend une plaque supérieure (1), deux plaques latérales (2) et une plaque inférieure (3). Un canal d'échappement (4) est enfermé avec la plaque supérieure (1), les deux plaques latérales (2) et la plaque inférieure (3). Le canal d'échappement (4) comprend un premier orifice d'admission d'air (41) au niveau d'une extrémité et un premier orifice d'évacuation d'air (42) sur l'autre extrémité. La plaque inférieure (3) est dotée d'une plaque de protection contre le vent (31) adjacente au premier orifice d'évacuation d'air (42). Par la fourniture de la plaque de protection contre le vent, la présente invention permet de régler des amplitudes d'un écoulement d'air et d'une pression statique, ce qui permet de satisfaire aux exigences de différents clients.
