Abstract: A heat exchanger including a corrugated heat transfer sheet having a first surface and a second surface on opposite sides thereof, a first flow channel for a first fluid flow in a first flow direction parallel to a longitudinal direction, and a second flow channel for a second fluid flow in a second flow direction parallel to the longitudinal direction, the second flow direction being opposite to the first flow direction. The heat exchanger includes a channel dividing system which provides the first flow channel and the second flow channel on opposite sides of the corrugated heat transfer sheet such that the first fluid flow is adapted to be in contact with the first surface, and the second fluid flow is adapted to be in contact with the second surface.

Abstract: A choke comprising a magnetic core having a centre line that forms a closed loop, the choke has a choke axis around which the magnetic core is located, and a coil wound around the magnetic core, the coil has a plurality of turns, each of the turns has a width perpendicular to lengthwise direction of the turn, and a thickness perpendicular to both lengthwise direction of the turn and the width. The coil has a cross-section whose shape varies along lengthwise direction of the coil, such that each turn has an inner portion and an outer portion whose width is substantially greater than width of the inner portion, the outer portion is located further from the choke axis than the inner portion.
