The invention relates to an infrared radiator embodied as a surface radiator, comprising a combustion chamber (14), which is limited by a gas permeable barrier and also by a radiating body (15). The radiating body contains a plurality of channels (21) and emits infrared radiation on the front surface thereof. Improved convective heat transmission is obtained therefrom and a longer service life is achieved by virtue of the fact that the barrier is made of a nozzle plate (12) comprising individual nozzles (29) and the channels (21) of the radiating body (15) are closed on the combustion chamber side at least in the region of the outlets of the nozzle (29), whereby deflector surfaces (22) are formed, against which the deflector surfaces of outlets of the nozzles (29) are orientated.
L'invention concerne un émetteur de rayons infrarouges se présentant sous la forme d'un émetteur plan, comprenant un foyer (14) qui est délimité, d'une part, par une barrière perméable aux gaz, et, d'autre part, par un corps rayonnant (15). Ce dernier contient une pluralité de canaux (21) et émet un rayonnement infrarouge au niveau de sa face avant. L'objectif de l'invention est de créer un émetteur de rayons infrarouges présentant un transfert de chaleur par convection amélioré et une grande durée de vie. A cet effet, la barrière est constituée d'une plaque à buses (12) présentant des buses individuelles (29) et les canaux (21) du corps rayonnant (15) sont fermés sur le côté foyer, au moins dans la zone des ouvertures de sortie des buses (29), ce qui permet de former des faces d'impact (22) vers lesquelles sont dirigées les ouvertures de sortie des buses (29).
