Will the angle of the marine heat exchanger affect heat exchange?

Plates with large herringbone angles have higher heat transfer coefficient and greater fluid resistance, on the contrary, plates with small herringbone angles have lower heat transfer coefficient and resistance. Research shows that the 120° herringbone angle has the best heat transfer effect. The smaller or larger the angle, the lower the heat transfer efficiency to achieve the maximum heat transfer effect.

In marine oil coolers, since the viscosity of oil is higher than that of water, making full use of a large-angle 120-degree plate will produce greater fluid resistance, and a 60-degree small angle plate has a lower heat transfer coefficient. Therefore, marine oil coolers often use two plate mixing methods. In the case of making full use of the allowable pressure drop, this is called a heat transfer hybrid design, and the heat transfer area can achieve the best effect. There are at least two types of reeds for each specification.

The heat transfer and pressure drop of the marine heat exchanger can be integrated through thermal mixing technology, so that it can run at an optimal working point. Internal bypass, dual-channel technology and unequal flow cross-section components provide a perfect solution for larger flow conditions on both sides of the medium.
