1. The oil cooler uses the bare tube (the surface not to roll the Fin) type heat transfer tube, the external membrane heat transfer coefficient is high, the anti-pollution ability is strong.
2. Oil cooler cooling pipe using high-quality copper tube, and processing into fin-shaped heat sink, product size, heat exchange area of large.
3. Oil cooler spiral guide plate, so that the cooled liquid into a helical continuous uniform rolling flow, to overcome the folded-flow guide plates produced by the hot and cold exchange efficiency.
4. The oil cooler adopts expansion tube sealing, which overcomes the bad changes caused by the high temperature welding of the material.
5. The oil cooler has good structure, stable sealing performance, high heat transfer efficiency, compact structure and small footprint.
