Abstract
The invention relates to a folded-edge engine oil cooler core with oil and water mixed. The cooler core comprises connection plates, chips, sealing plates, fins and solid sheets. The folded-edge engine oil cooler core is characterized in that bottom chips, upper chips, lower chips and the solid sheets are provided with bevel side covers. Oil channels and water channels are arranged correspondingly at two ends of a lower sealing plate, the bottom chips, the upper chips and the lower chips. Square teeth are distributed evenly in the fins, and the oil channels are arranged in the bottom chips corresponding to the fins. A connection plate A and a connection plate B are arranged on the bottom surface of the lower sealing plate, and an upper sealing plate is arranged on the solid sheets. Compared with the prior art, the folded-edge engine oil cooler core utilizes folded-edge brazing, not only the assembly is simple, but also the brazing is facilitated, and the product quality is improved effectively. Furthermore, oil and water are mixed to share one core body to form the turbulent flow of oil flows and cooling water flows, so that the product radiation effect is improved. The structure is particularly applicable to a cooling system of a high-power diesel engine.
