HEAT TRANSFER PIPE, HEAT TRANSFER PIPE UNIT, FLUID BED DRYER WITH HEAT TRANSFER PIPE, AND FLUID BED DRYER WITH HEAT TRANSFER PIPE UNIT

摘要

PROBLEM TO BE SOLVED: To provide a heat transfer pipe, a heat transfer pipe unit, a fluid bed dryer with the heat transfer pipe, and a fluid bed dryer with the heat transfer pipe unit which are capable of keeping efficiency of heat exchange high.;SOLUTION: A heat transfer pipe includes a pipe line 131 through which fluid is passed, and at least one turbulence accelerator 132 placed within the pipe line 131. The turbulence accelerator 132 generates turbulence, which disorders flow in an area of an inner wall side of the pipe line 131, in a downstream side in a flow direction of the fluid. This can prevent degradation of efficiency of heat exchange, and can keep the efficiency high.;COPYRIGHT: (C)2014,JPO&INPIT
