3) by becoming to be densely covered with the projection in array distribution by fin design, the effect of effective damping can be reached
Really, by being coated with boron nitride coating in groove between bumps, boron nitride coating layer has the heat conduction of excellence
Performance, it is possible to auxiliary heat dissipation, can improve heat exchange efficiency；
4) by using U heat exchange, when with elbow welding, only need to weld one end, compare traditional
Straight pipe type heat exchanger tube, during welding, two ends are required for welding, can improve work efficiency, reduce production cost,
And long flow path, flow velocity is high, good heat-transfer, and bearing capacity is strong, improves the performance of heat exchanger；To relatively
The gas of high blast, it is achieved little air quantity, the heat exchange of the big temperature difference；
5) by coating epoxy coating on side plate, epoxy resin is the preferable material of a sealing property
Material, this material can cover the irregular surface of microcosmic, play sealing effectiveness, prevent airflow leakage.
Part is embodied by further advantage of the present utility model, target and feature by description below, part
Also will be by research of the present utility model and practice be understood by the person skilled in the art.
