The utility model content
The purpose of this utility model is at the problems referred to above; a kind of tube-expanding device of air-condition heat exchanger is provided; heat exchanger copper pipe its internal whorl tooth in the pipe process that rises is effectively protected; under same material operating position; make the heat exchange efficiency of air-condition heat exchanger obtain increasing, improve the EER/COP of air-conditioning system.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of tube-expanding device of air-condition heat exchanger comprises the rise head and the bar that rises, and the described first end that rises is installed on the described boom end that rises and also can be provided with and the adaptive groove of heat exchanger copper pipe internal whorl odontoid at the described head surface that rises along this rod axis rotation of rising.
Be provided with installing hole at the described boom end that rises, the described first end that rises is inserted in this installing hole.
Between an insertion end and the installing hole radial thrust bearing is housed described rising, in the installing hole in this radial thrust bearing outside, end cap is housed also.
Be provided with connecting hole at the described first end that rises, this connecting hole is sleeved on the end of the described bar that rises.
Between boom end and the connecting hole radial thrust bearing is housed described rising.
The described head that rises by head is sphere shape, taper shape or arc surfaced.
The utility model tube-expanding device of air-condition heat exchanger compared with prior art, owing to be provided with and the adaptive groove of heat exchanger copper pipe internal whorl odontoid at the head surface that rises, when the swelling heat exchanger copper pipe, the groove of head of rising embeds in the thread of copper pipe inside, and the head that rises can also rotate with thread when rising by pipe, can effectively improve the present situation that air-condition heat exchanger internal thread tooth tip part profile of tooth is driven plain or polishes, improve the quality of production of air-condition heat exchanger, improve the EER/COP of air-conditioning system.
Radial thrust bearing is set at the head that rises with rising between the bar, can reduces the resistance of the head rotation of rising, it is more convenient to use.
