    • A heat transfer system (102) includes a heat exchanger (100) configured to transfer heat between a first fluid and a second fluid. The heat exchanger includes an outer sleeve (114) and a microchannel unit (116). The outer sleeve has an interior surface (200) defining a cavity (204) and an exterior surface (202) configured to be in direct thermal communication with the first fluid. The microchannel unit is received in the cavity. The microchannel unit has a plurality of microchannel s (230) configured to receive the second fluid therein and be in direct thermal communication with the second fluid. The microchannel unit has an exterior surface (232) in direct thermal communication with the interior surface of the outer sleeve to transfer heat therebetween. At least one of the interior surface of the outer sleeve and the exterior surface of the microchannel unit has grooves (260) defining breach channels (262) for the first fluid or the second fluid should a breach in the outer sleeve or the microchannel unit occur.
    • 传热系统(102)包括构造成在第一流体和第二流体之间传递热量的热交换器(100)。 热交换器包括外套筒(114)和微通道单元(116)。 外套筒具有限定腔体(204)的内表面(200)和构造成与第一流体直接热连通的外表面(202)。 微通道单元容纳在空腔中。 微通道单元具有多个构造成在其中接收第二流体并且与第二流体直接热连通的微通道s(230)。 微通道单元具有与外套筒的内表面直接热连通以在其间传递热量的外表面(232)。 外套筒的内表面和微通道单元的外表面中的至少一个具有凹槽(260),该凹槽(260)限定用于第一流体或第二流体的裂口通道(262),如果外套筒或微通道单元中出现裂口 。
