Abstract

The invention relates to an evaporator unit for a no-frost cooling device which comprises an evaporator (8), a tubular heating device (20) and a housing (7) which surrounds the evaporator (20) and the tubular heating device (8). Said tubular heating device (20) comprises a plurality of parallel tubular sections (21) which are connected together in such a manner that they form a single piece. Two parallel tubular sections (21) which are directly adjacent to each other are located at the beginning and at the end of the tubular heating device (20).
