Heat Sinks with Internal Pump for Water


	5-15

To provide a more consistent flow of cooled water than other heat sinks for water, these have a built-in pump and reservoir. The internal fan-cooled heat exchanger dissipates heat. Btu/hr. cooling capacity is based on water with an initial temperature difference of 77° F.

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 Exchangers for Sampling

Often used to monitor boiler water quality without shutting down the system, these heat exchangers cool hot liquid samples to safe temperatures for testing. Sample liquid flows through the tubes, and cold water from an external water supply flows around the tubes to cool the liquid in the tubes. Cooled sample water then flows out of the heat exchanger for analysis.
