Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger processing equipment, and more specifically to a vertical oil cooler. Background Art

[0002] In current mechanical equipment, engine oil is provided inside for the normal operation of mechanisms such as gearboxes.
