Fuel  -  Transmission Fluid  -  Engine Oil  -  Power Steering Fluid

How it Works:  Hot fuel or oil is chilled within the heat exchanger as its cooling medium is pumped through.  The cooling medium can either be (a) cold refrigerant return gas from the evaporator, or (b) ambient ram air chilled liquid using a standard finned heat exchanger, or (c) a stored, pre-chilled liquid.  As the cooling gas or liquid bathes the internal hot liquid-filled interface, heat is transferred from the hot liquid to the cooling medium. Hot liquid enters through one of the small fittings on the side of the tubular heat exchanger, and exits the other fitting AT A LOWER TEMPERATURE.

Applications:

• FUEL COOLER:  Prevents fuel starvation to the engine due to fuel vaporization, also referred to as "vapor lock".  Also improves engine power by providing high density liquid to the engine.

•  OIL & FLUID COOLER:  Oil can lose some of its lubricity when it gets overheated.  Since vehicle speed and engine fan rpm is constantly changing, overheating can occur when climbing hills, pulling a trailer, or carrying cargo because the cooling derived from air flow is not constant.  Standard finned transmission oil coolers are not very effective because they are dependent on ram air flow across their surfaces, and through grills that have an abundance of clutter which further obstructs air flow.  Automatic transmission performance would improve if a more constant source of oil cooling were available using the air conditioner to  reduce the oil temperatures.  It has been estimated that the oil life of transmission is doubled for every 20-degree drop in temperature, and that overheating causes 9 out of 10 transmission failures.

Accessories: 

• Digital Thermometer:  MONITOR OIL or FUEL TEMPERATURES using a dash-mounted 12 volts DC powered thermometer with lighted digital readout.  Includes:  Thermocouple cable (6' length), and stainless steel mounting faceplate.

• Thermocouple Housing:   Standard size inlet/out fittings are 5/16", 3/8, 1/2", 7/8" female pipe threads (NPT).  Custom sizes & tube configurations may be special ordered per customer's requirements.

• Custom Thermometer Housings:   Cool Flow can produce special purpose mounting brackets & housings or your special needs. 

• Remote Oil Thermostat:  REGULATE OIL TEMPERATURE automatically to about 180 deg F.  For use with transmission & engine oil coolers.  Prevents over-cooling in cold climates.  For use in cold climates, providing quicker warm-ups to operating temperature.

Installation:  The larger fittings on each end of the device are the inlet & outlet for cold refrigerant gas or another cooling medium.  The smaller fittings extending from the sides of the tube are the inlet & outlet of its internal heat exchange interface.  Other fitting combinations can be special ordered.  For best results, install so that the flow directions are opposite each other.
