Abstract
In a micro heat exchanger for the transfer of high area-specific amounts of heat from a heat source to a heat transfer medium, including a heat transfer structure with an inlet- and an outlet duct structure between which a plurality of passages extend through the heat transfer structure, the inlet and outlet duct structures are arranged in alternating order in the heat transfer area in close proximity to the heat source, with the inlet and outlet duct structure and the passages interconnecting the inlet and outlet structures covering the whole heat transfer area directly adjacent the heat source.
Claims10
A micro heat exchanger for the transfer of high area-specific amounts of heat from a heat source to a heat transfer medium comprising:
- a) a heat transfer structure with
- b) an inlet duct structure (1) and an outlet duct structure (2) each having a distribution volume (5, 6) with an inlet (7) and an outlet (8), respectively, for at least one heat transfer medium in the micro heat exchanger,
- c) a number of passages (3) extending between the inlet and outlet duct structures (1, 2) forming the only communication paths between the inlet and outlet duct structures (1, 2) for the heat exchanger medium, and
- d) said inlet and outlet duct structures (1, 2) being arranged intertwined in an alternating order in the transfer area in close proximity to the heat source and the inlet-duct structure (1), the outlet duct structure (2) and the passages (3) extending over the whole heat transfer area.
