The connecting elements of input and output of heat-exchange ZONE heater outlet and inlet collectors heat ENVIRONMENT (optional)

摘要

The invention relates to a connecting element of the input and output zones of heat exchange with the heater inlet and outlet manifolds heated medium - water, gas and steam and can be widely used in various industries, wherein heating is carried out fluids, gases and mixtures thereof.; In the first embodiment, (1) the connecting member is a bent foot 1 in the form of a tubular channel having a 1, a 5-3 times greater thickness than the heat exchanger tube, and an inner diameter equal to the inner diameter of the tube heat exchanger element. In a second embodiment (Figure 2) the connecting member is a bent foot 1 in a tubular channel with reinforcing plate 2, which can extend beyond the bent knee and be adapted to its introduction into the tube of the heat exchange element.; In both embodiments shown in the drawings the connecting member with the angle bend 90 °, but in practice, bending angle, depending on necessity, may be any.; With this arrangement, the inner diameters of the coil and the bent knee is completely the same and there is no resistance to the passage of feed water, and increasing the knee wall thickness in the first embodiment or the presence of reinforcing inserts in the connecting member in the second embodiment avoids the major causes of damage on this portion of the coil.; Furthermore, there is no need to acquire new coil, because there is the possibility of using coils with replacement of old only the defective wall thickness are already destroyed or coupling element on the thick-walled bent knee or knee bent with reinforcing plate. This makes the construction more economical, because the cost of a new coil is much higher than the cost of one bent knee.; 3 PF 3 yl.
