This SAE Recommended Practice is applicable to oil-to-air oil coolers installed on mobile or stationary equipment. This document outlines the method of procuring the test data to determine operating characteristics of the oil cooling system and the interpretation of the test results.

This SAE Information Report is a source of information concerning the basic properties of engine coolants which are satisfactory for use in internal combustion engines. Engine coolant concentrate (antifreeze) must provide adequate corrosion protection, lower the freezing point, and raise the boiling point of the engine coolant. For additional information on engine coolants, refer to ASTM D3306, ASTM D4985, and ASTM D6210.

This recommended practice is intended to outline basic nomenclature and terminology in common use for engine charge air coolers. An Engine Charge Air Cooler is a heat exchanger used to cool the charge air of an internal combustion engine after it has been compressed by an exhaust gas driven turbocharger and/or mechanically driven blower. The use of an engine charge air cooler allows increased engine output because of the denser and cooler air available for combustion. Normal cooling sources are the engine’s coolant, a raw water source, or air. Engine charge air coolers are often referred to as either Intercoolers or Aftercoolers depending upon their location, relative to the final compression stage, in the air induction system. Nomenclature sketches are presented below for the following general types of engine charge air coolers:

It is necessary to identify and attempt to evaluate the characteristics of an application which can have an effect on fan durability. Failures almost always occur in fatigue, so careful attention should be paid to avoid resonance or forced vibration of the fan. This section considers vibrational inputs, fan natural frequencies, and operating speed as part of the initial structural integrity analysis. A fan application fact sheet (Table 1) is recommended as a form to communicate between user and fan supplier.

Three levels of fan structural analysis are included in this practice: 1 Initial Structural Integrity 2 In-vehicle Testing 3 Durability Test Methods The Initial Structural Integrity section describes analytical and test methods used to predict potential resonance and, therefore, possible fatigue accumulation. The In-vehicle (or machine) section enumerates the general procedure used to conduct a fan strain gage test. Various considerations that may affect the outcome of strain gage data have been described for the user of this procedure to adapt/discard depending on the particular application. The Durability Test Methods section describes the detailed test procedures that may be used depending on type of fan, equipment availability, and end objective. Each of the previous levels builds upon information derived from the previous level. Engineering judgment is required as to the applicability of each level to a different vehicle environment or a new fan design.
