Description
Technical field
The invention belongs to technical field of mechanical processing, and in particular to a kind of finned heat exchanger electric tube expander.
Background technology
Finned heat exchanger is with refrigerant (water at low temperature or brine) cooling air, heating agent (steam or high-temperature water, oil) heating
A kind of heat transmission equipment of air.The core component " finned tube " of finned heat exchanger is by adding on base tube by professional machines
Achieve the purpose that augmentation of heat transfer after dress fin.
Generally aluminum pipe or the copper pipe of base tube, copper pipe surface roll the fin for having shape of threads, increase copper pipe by fin
Heat exchange surface area, the heat exchanger effectiveness of cooler is improved with this.Based on this, it is desirable to which the fin on cooler copper tubes must be close
It is incorporated on the tube wall of copper pipe, it is impossible to loosen, if loosening, the gap of air circulation certainly will occur, and then influence heat exchange effect
Rate, thus, cooler copper tubes and combining closely for fin are to be swollen by electric tube expander and realized to the diameter of copper pipe.
The working size of existing electric tube expander is smaller, can only the shorter finned cooling pipe of processing length, with identical work
Make principle increase cooling tube length after, will result in base tube breakage, or push away it is swollen during base tube burst apart, cause waste product.
And existing electric tube expander, more using swollen or an auxetic processing method is once pushed away, the base tube of this processing method processing only produces
A plastic deformation is given birth to, in use for some time, some positions of base tube can deform, and then cause fin to come off, and reduce
The heat exchange efficiency of whole heat exchanger；And it is this once push away swollen or an auxetic processing method, in processing, swollen head meeting and base tube
Certain metal fragment is produced in inner wall extruding, and time processing cannot peel off these chips from base tube inner wall completely, such heat exchange
In use for some time, the metal fragment not being completely exfoliated can come off device under the washing away of coolant, these chips may
Block heat exchanger or the damage heat exchanger pump housing.
