| 摘要 |
The invention relates to a heat exchanger for small components through which a fluid may flow, made from several individual pieces, exclusively produced by forming and joined to each other, to an inlet channel, a planar heat exchange element and an outlet channel. The heat exchange element comprises an upper and lower side which may be connected to at least one heat source, characterized in that the inlet channel is made from a metal connector tube which continuously enlarges towards the heat exchange element on the inlet side up to the total cross-sectional flow area of the inlet side and face of the heat exchange element and the outlet channel continuously tapers away from the heat exchanger on the outlet side from the total cross-sectional flow area of the output side end face of the heat exchanger element to a metal connector tube. The heat exchange element comprises a channel-like inner structure running in the flow direction to increase the heat transfer, which runs within the element from the lower side to the upper side.
