FIELD: spray systems.
SUBSTANCE: group of inventions relates to a spray unit and a spray device. The spray unit includes a tubular heating unit and a fluid-conducting element. The fluid-conducting element is wrapped around the outer periphery of the tubular heating unit or mounted on the inner peripheral surface of the tubular heating unit. The tubular heating unit includes an annular connecting part, at least two heating parts connected to one end surface of the connecting part and located around the end surface, and electrode parts connected to one end of the heating parts away from the connecting part. Each side of the two opposite sides of one heating part faces the corresponding side of the adjacent heating part with a gap between them. At least two heating parts are connected in series by means of a connecting part.
EFFECT: increasing the structural strength of the heating unit, increasing the resistance value compared to other heating elements of the same volume.
