In a multilayer heat exchanger of the present invention, a plurality of heat exchange units for performing heat exchange of a fluid fed from a plurality of compressors is stacked. Each of the heat exchange units has a structure that pluralities of flow passage plates and cooling plates are stacked. Concave grooves formed on surfaces are formed as flow passages of the fluid in the flow passage plates and cooling plates. The flow passage plates and cooling plates are made of metal, the flow passages are formed by chemical etching, and the stacked metal flow passage plates and cooling plates are bonded to each other by diffusion-bonding. Further, each of the heat exchange units is in one-to-one correspondence with each of the compressors. |
