PURPOSE:To obtain the inflow structure of the multi-tube type heat exchanger, which improves the low abrasion property and vibration preventing property of heat transfer tubes and uniforms the balance of heat transfer characteristics of respective parts of each heat transfer tube, by a method wherein the notched sections of baffle plates for flowing cylinder side fluid into the axial direction of heat transfer tube group meandering in zigzag are provided inside a fluid guide cylinder in the flow of the cylinder side fluid. CONSTITUTION:The cylinder side fluid enters into the heat exchanger through a cylinder side fluid inlet nozzle 1, collides against the fluid guide cylinder 2' and flows along the inner peripheral part of the cylinder 3. Then, a part of the fluid flows through a space between the cylinder 3 and the fluid guide cylinder 2' under climbing over the cylinder 2' and the other part thereof flows through holes 13, thus all of it flows into the group of heat transfer tubes 4. Further, the cylinder side fluid flows through the heat transfer tube group 4 into the direction opposing to the flow direction in the inlet nozzle 1 and flows into the meandering flow section consisting of the first baffle plate 5 and the second baffle plate 5' through the notched section 12. Thereafter, the cylinder side fluid flows meandering through the heat transfer tube group 4 sequentially since numbers of baffle plates 5 are equipped and, then, flows out of a cylinder side fluid outlet nozzle 8. |
