| 摘要 |
The invention relates to a pipe arrangement for a fluid heating assembly formed of a single heat conductive pipe (1), comprising a stack, along a main axis (A) of the arrangement, of elongate loops (L1, L2, L3, L4) of said pipe (1) extending radially from the main axis (A) in directions substantially orthogonal to said main axis (A). The extension directions of two successive loops form a substantially constant angle between them, and the parts of the loops (L1, L2, L3, L4), in the stack, that are proximal in relation to the main axis (A) define a central channel around the main axis (A). The invention also relates to a fluid heating assembly comprising such a pipe arrangement, and to a portable hot beverage preparation machine comprising this fluid heating assembly. |
