Murphy plate finned tube heat exchanger has some obvious advantages in operation, especially in the field of air to air heat transfer, especially in the field of ultra-high temperature air to air heat transfer. To a certain extent, it has become the upgrading product of the tube, heat pipe and finned tube heat exchanger. The main characteristics of Murphy plate finned tube heat exchanger: the finned tube heat exchanger can be designed with elastic structure, which can effectively solve the problem of its thermal expansion; there are rich test and actual operation data as support, through constant correction of the calculation formula, the calculation error is within 5%, and more than 95% of the equipment operation can reach the design parameters.
