    Abstract: A machine system includes a compressor, and a cooler having an inlet tank to receive compressed air from the compressor, and a header assembly attached to the inlet tank and including a plurality of cooling tubes supported in the header and each having an external heat exchange surface exposed to a flow of cooling air. The cooler further includes a plurality of graphite pack seals each extending peripherally around one of the cooling tubes, and a clamping assembly clamping the pack seals against the header to squeeze the pack seals into sealing contact with the cooling tubes and the header.

    Abstract: A system for determining a remaining useful life of a cooling component operatively connected to a prime mover. A controller performs a thermal strain analysis that includes determining the power output of the prime mover based upon sensor signals, determining a temperature output of the prime mover based upon the power output, determining a temperature at each of the plurality of analysis locations based upon the temperature output, determining a temperature difference based upon the temperature at each respective one of the plurality of analysis locations, and determining a thermal strain based upon the temperature difference. The controller repeats the thermal strain analysis at time intervals over a period of time, determines an accumulated damage for the cooling component based upon the thermal strain from each thermal strain analysis, and determines a remaining useful life of the cooling component based upon the material characteristics and the accumulated damage.

    Abstract: A heat exchanger with a first manifold and a second manifold. The heat exchanger includes tubes having first and second ends. The tubes connect to the first manifold at the first end and the second manifold at the second end establishing fluid communication between the manifolds. The tubes are arranged parallel and forming gaps between tubes. The heat exchanger includes fin matrices formed from fins that span the gaps and extend from the first end to the second end. At least two adjacent tubes define an expansion gap that accommodates thermal expansion.

    Abstract translation: 具有第一歧管和第二歧管的热交换器。 热交换器包括具有第一和第二端的管。 管在第一端连接到第一歧管，在第二端连接第二歧管，从而在歧管之间建立流体连通。 管平行布置并在管之间形成间隙。 热交换器包括由翅片形成的鳍状物矩阵，翅片跨越间隙并从第一端延伸到第二端。 至少两个相邻的管限定了适应热膨胀的膨胀间隙。
