Fluid flow channel with efficiency-increasing transformations

摘要

The invention relates to a fluid flow channel in a heat exchanger (280, 360, 395, 400) or in a cooling / heating element (430) for a heat-absorbing or heat-emitting first working fluid (310), comprising: a first channel wall (110) and a second channel wall ( 120), which are arranged opposite one another and via which the first working fluid (310) flowing in the fluid flow channel (100) with at least one further working fluid of the heat exchanger (280, 360, 395, 400) or with at least one further component or with the surroundings of the cooling - / heating element (430) is in heat exchange, first deformations (130) extending into the fluid flow channel (100), each formed with the opposite channel wall (110, 120) or in the opposite channel wall (110, 120), in the fluid flow channel (100 ) extending first formings (130) are integrally or positively connected and i n second deformations (140) extending into the fluid flow channel (100), each at a predetermined spacing (160) from the opposite channel wall (110, 120) or from those formed in the opposite channel wall (110, 120), into the fluid flow channel (100) extending second formations (140) are spaced.
