Description
Technical field
The utility model 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 by professional machines on base tube
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 improves the heat exchanger effectiveness of cooler with this.Based on this, it is desirable that the fin on cooler copper tubes must be close
It is incorporated on the tube wall of copper pipe, cannot 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 to the diameter of copper pipe by electric tube expander and realized.
The working size of existing electric tube expander is smaller, can only the shorter finned cooling pipe of processing length, with identical work
After making the length that principle increases cooling tube, base tube breakage is will result in, or base tube bursts apart during pushing away swollen, causes waste product.
And existing electric tube expander mostly uses and once pushes away swollen or an auxetic processing method, and 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 fin is caused to fall off, and reduce
The heat exchange efficiency of entire heat exchanger；And it is this once push away swollen or an auxetic processing method, in processing, swollen head meeting and base tube
Inner wall, which squeezes, produces certain metal fragment, and time processing cannot remove these clasts from base tube inner wall completely, such heat exchange
In use for some time, the metal fragment not being completely exfoliated can fall off device under the washing away of coolant liquid, these clasts may
Block heat exchanger or the damage heat exchanger pump housing.
