Heat Sinks for Oil
 |
Dozens of fins and coolant tubes quickly dissipate excess heat. Also known as oil coolers, these heat sinks cool hydraulic fluid and lubricating oil in cylinders and compressors. Cooling and flow capacities are based on 50 SSU oil, 1,000 feet per minute of air, a 50° F initial temperature difference, and a 10 psi pressure drop.
Bypass—Heat sinks with a bypass prevent damage to the cooling fins by diverting pressurized oil. They’re often used in machines that are started up while cold. Once the oil heats up and the pressure drops, flow through the cooling tubes resumes.

Heat Sink Shown with Pipe |
Turn your pipe or tube into a heat sink. A hinged design makes these heat sinks simple to wrap around an existing line—no need to cut into your line and drain the liquid to install a heat sink. Multiple fins create a large surface to draw heat away quickly. As they cool down the contents of your line, they heat the space around the heat sink, similar to how radiant heat works.
Secure them together with the included fasteners. You don't need to worry about using heat transfer compounds or putty with these.
Cooling Capacity—Cooling capacity is based on 180° F water flowing through your line at one gallon per minute in a space with an ambient temperature of 65° F and normal airflow.
