Abstract: A shunt tank assembly for a cooling system is provided. The shunt tank assembly includes a vent tube, a shunt tank, and an inlet port provided on the shunt tank. The inlet port is in fluid communication with the vent tube. The shunt tank assembly also includes an insert disposed in the inlet port. The shunt tank assembly further includes a drop tube. The drop tube includes a plug portion having a first length and received within the insert. The drop tube includes a transition portion tapered with respect to the plug portion. The drop tube includes a tube portion extending from the transition portion and terminating with a chamfered end. The tube portion has a second length greater than the first length of the plug portion. The tube portion is bent such that the chamfered end is disposed below an average coolant level of the shunt tank.

Abstract: An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a first header. The first header may include a plurality of slots each having a recessed groove. The ATAAC may further comprise a plurality of core tubes each including a first end inserted in a respective one of the slots of the first header. The ATAAC may further comprise a plurality of mechanical joints each connecting the first end of one of the core tubes to the first header. Each of the mechanical joints may include a C-ring inserted in the recessed groove of one of the slots, and a clamp clamping the core tube to the first header. The C-ring and the clamp may both be formed from a metallic material.

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.
