Embodiment
1, FSA air cleaner
That the FSA air cleaner has is lightweight, good filtration effect, draft loss is little, noise is low, self-cleaning, the advantage such as non-maintaining.It makes dust, rainwater and flow separation by certain centrifugal action, and discharges by dust-exhausting port after can being collected by sedimentation rapidly.
Critical piece is: (a). mozzle: air is led and accelerates;
(b) chimney filter one: gas turns is also collected dust;
(c) chimney filter two: collect dust and discharge.
2, cooler
The heat-delivery surface of cooler is to adopt the netted thin plate of aluminium matter to rearrange by specific structural order.Other all cooler parts adopt aluminium sheet or casting aluminium material to make too.Because considering, the medium that is cooled and air have different heating power and flow behavior, so the runner design on netted thin plate two sides becomes different molded line.The coolant side of netted heat radiation book plate is welded together in twos relatively, form airtight passage block; Again with some passages and top shell i.e. formation welded together heat radiation tube sheet.
3, blower fan assembly
Fan casing in the blower fan assembly is the link between cooler and blower fan, is steel construction piece.2 centrifugal blowers are set in cooling device, in Fan casing dividing plate plenum area is divided into 2 independently parts, every Fans has separately independently air chamber, such layout can effectively be avoided the short circuit reflux problem of air stream.
2 centrifugal blowers are to determine according to the requirement of the thermodynamic property of device and structure, the large and compact conformation of air quantity, and cooling performance is good.
Expansion tank 4 is installed in the rear left side of cooling system, and reactor 5 is installed in the rear middle side of cooling system, and water pump 6 is installed in the rear right side of cooling system.
Pipe-line system 7 connects cooler 2, water pump 6 and current transformer, for coolant flow.
Coolant channel adopts efficient serrated fin, and the wind passage adopts rippled fin, and rippled fin is made simple, and heat transfer efficiency is higher, simultaneously dirt be easier to by, can alleviate to a certain extent the catkin blockage problem.
8, system framework and other parts
Cooling system system framework, base plate composition, ventilating duct etc. all use the special rolling-mill section that can satisfy-40 ℃ of instructions for uses, and all parts are bolted fixing.Fasten and connect the surface and all add encapsulant, guarantee the air-tightness of air duct.
System framework uses the integral solder structure, and stronger intensity and rigidity are arranged.
Base plate forms, and is designed to and can splits respectively structure, is convenient to Maintenance and Repair.
