阅读说明：本技术 热交换器 (Heat exchanger ) 是由 C.J.帕尔默 于 2020-01-14 设计创作，主要内容包括：本公开涉及热交换器,其可例如用于气体涡轮引擎或用于其他应用。示例性实施方案包括热交换器(200),该热交换器包括：外表面(201),其用于与在外表面(201)之上通过的外部流体流(202)交换热量；第一流体通道(203),其从第一流体入口(204)延伸穿过热交换器(200)至第一流体出口(205),该第一流体通道(203)的第一部分(206)邻近外表面(201)沿着热交换器(200)延伸,以用于第一冷却流体穿过第一流体通道(203)以与外部流体流(202)交换热量；和第二流体通道(208),其从第二流体入口(209)延伸穿过热交换器(200)至位于外表面(201)处的第二流体出口(210),以将第二冷却流体从第二流体入口(209)递送到外部流体流(202)中。(The present disclosure relates to heat exchangers, which may be used, for example, in gas turbine engines or in other applications. An exemplary embodiment includes a heat exchanger (200) comprising: an outer surface (201) for exchanging heat with an external fluid flow (202) passing over the outer surface (201); a first fluid channel (203) extending through the heat exchanger (200) from a first fluid inlet (204) to a first fluid outlet (205), a first portion (206) of the first fluid channel (203) extending along the heat exchanger (200) adjacent the outer surface (201) for a first cooling fluid to pass through the first fluid channel (203) to exchange heat with an external fluid flow (202); and a second fluid channel (208) extending through the heat exchanger (200) from the second fluid inlet (209) to a second fluid outlet (210) at the outer surface (201) to deliver a second cooling fluid from the second fluid inlet (209) into the external fluid flow (202).)
