1. A heat exchanger, comprising:
a heat exchanging body, defining a plurality of first micro-channels and a plurality of second micro-channels; and
a fluid-collecting tube assembly, comprising a first fluid-collecting tube and a second fluid-collecting tube, wherein the first fluid-collecting tube defines a first fluid-collecting channel, the first fluid-collecting channel is configured to provide a first cooling medium to the plurality of first micro-channels and/or to collect the first cooling medium that flows through the plurality of first micro-channels; the second fluid-collecting tube defines a second fluid-collecting channel, the second fluid-collecting channel is configured to provide a second cooling medium to the plurality of second micro-channels and/or to collect the second cooling medium that flows through the plurality of second micro-channels, and heat is exchanged between the first cooling medium flowing through the plurality of first micro-channels and the second cooling medium flowing through the plurality of second micro-channels;
wherein the heat exchanging body comprises a plate body, the plurality of first micro-channels and the plurality of second micro-channels are arranged alternately in a same row in the plate body.
