The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Air conditioner heat-exchanger brass pipe defect servicing technique method, heat exchanger of air condition at first that defectiveness is to be repaired is put into water, detects defective copper pipe with the method for inflating bubbling.
With cutting nippers or diagonal cutting pliers copper pipe " U " type is partly cut off; " U " type copper pipe (hair fastener pipe) just has been divided into two sections like this.Also can cut out copper sheet earlier, cut off " U " type part of copper pipe again.
Then, one section copper pipe 4 wherein is placed on the plastic mattress of workbench.Source of the gas is connected with pneumatic hammer, pneumatic hammer is connected with connector 1; Knife bar 3 and blade 2 assemblings; The bar that will rise assembles with the head that rises; Perform the preparation of repairing.
Existing connector is a tip as shown in Figure 1.As shown in Figure 2, connector 1 of the present invention is not a tip, and has a blind hole 11, and blind hole 11 is used to entangle knife bar 3.Referring to Fig. 3,4, blade 2 comprises two parallel blade body 21,22, one installing handles 23.Two parallel blade body 21,22 are arranged on of installing handle 23, and two parallel blade 21,22 and installing handles 23 are integrative-structure.Referring to Fig. 5, the internal diameter size of the external diameter of knife bar 3 and copper pipe 4 matches, and a side of one of knife bar 3 has a blind hole 31, and blind hole 31 is used to install the installing handle 23 of blade 2.Knife bar 3 should long enough, is beneficial under the driving of pneumatic hammer blade 2 shifted onto copper pipe 4 bottoms.
Referring to Fig. 6.Knife bar 3 is placed on the flared end 41 of copper pipe 4, and one that specifically knife bar 3 is equipped with blade 2 is placed on flared end 41.Knife bar 3 is hit copper pipe 4 and copper pipe 4 is pushed up through " U " type part the copper pipe wall of copper pipe 4 a cutting-out copper sheet 40 that links to each other with copper pipe 4 (copper sheet 40 width are identical with blade 2 width) with pneumatic hammer.This step is actually from copper pipe 4 upper edge axis directions and crosses out one, and will draw the copper pipe wall.After like this this copper sheet 40 being pulled out, copper pipe wall two side sections will be inwardly recessed, occurs becoming flexible, and is convenient to whole copper pipe 4 pulled out.
The breach that described knife bar 3 ejects is enlarged at copper pipe " U " type part place end 42 with nipper plier, on the copper pipe wall of copper pipe 4, can be clear that the part of being cut by blade 2.Make the iron wire 5 that can make things convenient for the back like this and pull out the copper sheet that blade 2 is downcut.
Remove at the part copper pipe that copper pipe " U " type part place end 42 will exceed the fin 44 on the copper pipe 4 with nipper plier, remove and cut the copper sheet 40 at place by blade.Can be clear that the copper sheet 40 that is cut after removing.The purpose of this step is that by external diameter is bigger than fin 44 internal diameters the part copper pipe that exceeds the fin 44 on the copper pipe 4 is removed, and eliminates the obstruction of next step being pulled out copper sheet.Stay the copper sheet 40 that exceeds fin 44, made things convenient for the past post-tensioning of the copper sheet of back.
Referring to Fig. 7.With pulling out tool, iron wire 5 is passed copper pipe 4 from copper pipe flared end 41, with iron wire 5 copper sheet 40 is entangled toward post-tensioning; Appear at the flared end 41 of described copper pipe until copper sheet 40, and exceed described copper pipe 4 mouths of pipe 10～20cm.After copper sheet 40 was pulled out, the contact-making surface of copper pipe wall and fin 44 inwalls was just littler, and the frictional force that can produce is also littler, had made things convenient for the pulling out of whole copper pipe 4 of back.After copper sheet 40 pulled out, copper pipe wall and fin 44 inwalls had become matched in clearance by tight fit, be beneficial to next step defective copper pipe 4 is all pulled out.
With nipper plier with copper pipe 4 reducings; Contract in the copper pipe wall, littler than fin 44 internal diameters, copper pipe 4 defective parts contract in all.Like this, the contact-making surface of copper pipe wall and fin inwall is littler, and the frictional force that can produce is also littler.Can protect the aluminium foil on fin 44 inwalls like this, not make aluminium foil produce distortion as far as possible, prevent to influence the coefficient of heat transfer of interchanger.
With the tiger pincers described copper sheet 40 is clamped toward post-tensioning, be drawn out together until copper pipe 4 and described copper sheet 40.The plumber's preface that rises is arranged when producing heat exchanger of air condition---two sections straight line portion external diameters of U type pipe being risen greatly, make it closely to contact with peripheral aluminium foil, is interference fit, is convenient to heat exchange.So copper pipe 4 is difficult for directly pulling out, and directly draws copper pipe to destroy aluminium foil easily.So this step adopts the method for drawing copper sheet 40, pulls out whole copper pipe.
Another section copper pipe is also extracted out from fin by above-mentioned steps.
New " U " type copper pipe is inserted in two fins 44.Use the pneumatic hammer bar that will rise to hit, make it to present interference fit with aluminium foil into the new copper pipe pipe that rises.Use at last that the heat exchanger comb is flat with described fin comb, reinstatement gets final product.
Certainly, the present invention is not limited only to keep in repair air conditioner heat-exchanger brass pipe, is used for the maintenance of finned copper pipe of the heat exchanger of other aspect, also can use the present invention.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
