The heat exchanger comprises a lower metal sheet, —an upper metal sheet, and a fin sheet delimiting the fins. The lower metal sheet, the upper metal sheet and the fin sheet form a three-layer structure wound in a spiral, whereby the lower metal sheet and the upper metal sheet delimit a first passage for the circulation of a first fluid. The heat exchanger has a set of spacers arranged in the first passage, whereby these spacers are rods separate from the lower and upper metal sheets. |
