    • The invention relates to a flow channel (41, 41 ', 61, 61 ', 71, 71 ', 81, 81' 91, 91 ') for a hear exchanger (30, 40) for exchanging heat between a first fluid (31 ) and a second fluid (33). Said flow channel comprises a channel cover (63, 63', 73, 73', 83, 83', 93, 93') provided with a space (67) surrounded by the inner side of the channel cover (65); a plurality of partitions (69, 79, 79', 89, 89', 99) that are arranged on the inner side of the channel cover (65) in said space (67), said flow channel (1) comprising, perpendicular to a flow channel axis (94), a cross-section that can be traversed and embodied for guiding the first fluid (31 ) in the inner chamber (67). The aim of the invention is ensure an improved transfer of heat with a more acceptable drop of pressure and a reduced risk of blocking. As a result, a hydraulic diameter in the region of between 1,5 mm and 6 mm, defined as the quadruple of the ratio between the surface of the cross-section that is traversed and the perimeter that can be moistened by the fluid. The invention also relates to a heat exchanger (30, 40), comprising a block having a plurality of flow channels (41, 41 ', 61, 61 ', 71, 71 ', 81, 81 ', 91, 91 ') of said type, through which the first fluid (31) flows and fluidically connected by a fluid connection. The invention further relates to a charge-air system, an exhaust gas recycling system and to the use of the heat exchanger.
    • 一种用于在第一流体和第二流体之间进行热交换的热交换器的流动通道,该流动通道具有垂直于流动通道轴线的横向横截面,该流动通道提供改进的热传递 具有可接受的压力下降和降低的阻塞风险。 流动通道具有液压直径,定义为横穿横截面的表面与可被流体润湿的周长之间的比例为1.5mm至6mm之间的四倍。 也是具有这种类型的多个流动通道的热交换器,第一流体通过该流路流动并通过流体连接流体连接。 还有一种具有这种流动通道的充气系统和废气回收系统。
