Description
Technical field
The utility model relates to technical field of heat exchange, especially relates to a kind of heat exchanger fin and adopts the dislocation type heat exchanger of this heat exchanger fin.
Background technology
Heat exchanger is a kind of energy-saving equipment realizing heat transmission between material between two or more fluid of different temperatures, make heat pass to the lower fluid of temperature by higher fluid, fluid temperature (F.T.) is made to reach flow process set quota, to meet the needs of process condition, simultaneously also one of capital equipment improving energy utilization rate.
Between chimney breast, usually heat exchanger can be installed at the burning zone of combustor, be used for heating coolant media (being generally water).Heat exchanger used herein is generally the heat exchanger by multiple heat exchanger fin closed assembly.
Traditional heat exchanger fin has two kinds of forms: tandem and parallel.
, there is not branch road in the import of tandem heat exchanger fin, heat exchanger tube and the one whole piece pipeline of outlet for linking together.The stroke of the heat transferring medium of this structure is long, and heat exchange efficiency is not high.
Many heat exchanger tubes in parallel between parallel heat exchanger fin import and outlet, there are following several shortcomings in this heat exchanger fin:
1. the water inlet of existing heat exchanger fin and delivery port are generally positioned at homonymy, or are positioned at centre position; Such design does not cause stroke when heat transferring medium flows through each heat exchanger tube not etc., the heat-exchange time of the heat transferring medium in the heat exchanger tube that stroke is shorter is shorter, and the heat-exchange time of heat transferring medium in the longer heat exchanger tube of stroke is longer, thus cause the non-uniform temperature of heat exchanger each several part, have impact on heat exchange efficiency;
2. the water inlet pipe of existing heat exchanger fin and the cross-sectional area of outlet pipe are only the cross-sectional areas being a bit larger tham single heat exchange tube, but are less than the cross-sectional area sum of all heat exchanger tubes; Such design brings the problem of the pressure inequality in each heat exchanger tube, distance water inlet pipe and the nearer heat exchange overpressure of outlet pipe larger, the water yield is more, and distance water inlet pipe and outlet pipe heat exchange overpressure far away less, the water yield is also less, thus the heat exchange causing regional area is not enough, affects final heat exchange efficiency.
Superposed by multi-disc heat exchanger fin, constitute heat exchanger.And in order to improve the heat exchange area of heat exchanger, be typically designed to dislocation type heat exchanger.But no matter be tandem heat exchanger fin or parallel heat exchanger fin, all need the heat exchanging fin of Design and manufacture two profiles number, and its interval is assembled, thus obtain the heat exchanger that misplaces; Design and manufacture all needs two sets of plan, and cost is higher.
