Abstract: An air to air heat exchanger is provided including a core having a plurality of alternately stacked first layers and second layers. Each first layer includes a plurality of first modules having corrugated fins that define a plurality of first fluid flow paths. The first modules are aligned to fluidly couple the first fluid flow paths. Each second layer includes at least one second module having corrugated fins that define a plurality of second fluid flow paths. At least one second layer includes a third module having a plurality of corrugated fins that define a plurality of third fluid flow paths. The third module is arranged such that the third fluid flow paths are parallel to the second fluid flow paths. A number of corrugated fins formed in the third module is less than a number of corrugated fins formed in the second module.

Abstract translation: 提供一种空气 - 空气热交换器，包括具有多个交替层叠的第一层和第二层的芯。 每个第一层包括具有限定多个第一流体流动路径的波纹状翅片的多个第一模块。 第一模块对准以流体地联接第一流体流动路径。 每个第二层包括具有限定多个第二流体流动路径的波纹状翅片的至少一个第二模块。 至少一个第二层包括具有限定多个第三流体流动路径的多个波纹状翅片的第三模块。 第三模块被布置成使得第三流体流动路径平行于第二流体流动路径。 形成在第三模块中的多个波纹状散热片小于形成在第二模块中的多个波纹状散热片。
