The implication that member is generally understood that is identical.Term used in the description is intended merely to describe concrete enforcement purpose, it is not intended that in limit
This utility model processed.
As shown in Figure 1, 2, this cooling system is connected to cool down on unit equipment 7, including back pool 1, heat exchanger 2, diversion
Pump 3, go out water pump 4, blow device 5, exhaust apparatus 6.Wherein heat exchanger 2 is again by water inlet pipe 2-1, outlet pipe 2-2 and uniformly
The cooling coil 2-3 composition of arrangement.
Concrete, as it is shown in figure 1, back pool 1 is provided with the primer pump 3 introducing stream, it is additionally provided with out water pump 4 simultaneously.Change
Hot device 2 one end connects water pump 4, and the other end connects need to cool down unit equipment 7, and the introducing water of back pool 1 cools down through heat exchanger 2
Back pool 1 circulating cooling it is connected to the most by the road after entering unit equipment.
Concrete, as in figure 2 it is shown, heat exchanger is calandria structure, it is positioned in the tailwater channel that need to cool down near unit equipment 7.
Including with go out the water inlet pipe 2-1 that water pump 4 is connected, and the outlet pipe 2-2 that unit equipment 7 is connected need to be cooled down, and evenly distributed and connect
The cooling coil 2-3 being connected between inlet tube and outlet tube, wherein cooling coil tube wall and tail water water in a canal carry out heat exchange.
Described heat exchanger arranges one group, as shown in Figure 2.Or at least two groups, and two adjacent groups heat exchanger employing series system is even
Connecing, adjacent water inlet pipe is integral by Flange joint with outlet pipe with water inlet pipe, adjacent outlet pipe.
Described water inlet pipe, outlet pipe and each cooling coil outer wall are equipped with anticorrosion deposited metal.
Concrete, as it is shown in figure 1, the water inlet of heat exchanger 2 accesses is provided with blow device 5 on pipeline, water outlet picks out and sets on pipeline
It is equipped with exhaust apparatus 6.
1, the design of system: whole water system is by water pump, heat exchanger, unit cooler, back pool, water pipe and adnexa
And supply and discharge water pipe composition.The route of water circulation is water pump → heat exchanger → unit cooler → back pool → water pump, and circulating cooling supplies
Water system is as shown in Figure 1.
2, the design of heat exchanger: heat exchanger is the core component of circulating water supply system, cooling water is by the heat master after unit parts
System tail water to be leaned on is taken away, and therefore designing heat exchanger is that system is the most crucial.This heat exchanger is disposed on servicing tail near unit
In water channel.
1) pattern of heat exchanger, the position that its pattern is placed with it is relevant, and heat exchanger is generally placed upon in tail water channel, is available for choosing
That selects has board-like and calandria, and general consideration power station manufactures draws materials, and clears up maintenance at ordinary times, reduces the factors such as cost and uses calandria to change
Hot device, as shown in Figure 2.
2) thermodynamic metering of heat exchanger:
By thermodynamics fundamental formular: Q=kF Δ tm, ask for the area of heat exchanger
Q: for the heat output of heat exchanger
Δtm=for outer fluid mean temperature difference Δ t in heat exchangerm=tL1-tL2
tL1: for tail water design temperature
tL2: for the mean temperature of fluid in heat exchanger
K: for heat exchanger heat transfer system, it is made up of three parts: the heat absorption coefficient of internal face, the coefficient of conductivity of wall, the dissipating of outer wall
Hot coefficient.The test method instructed by the theory of similarity, is combined into n number group the numerous variablees affecting fluid heat transferring coefficient, this
A little several groups are referred to as similarity criterion, ask for k value.
F: heat exchange area F
