Description
Technical field
The present invention relates to a kind of technology of field of heat exchange, specifically a kind of S types fold heat exchange flat tube.
Background technology
The evaporator of current domestic air-conditioning system and condenser, the fan coil of central air conditioner system, the heat exchange of gas heater
The general fin-tube type heat exchanger using copper pipe aluminum fin structure type in the heat transmission equipments such as device.Copper pipe is pipe in heat exchanger, due to
Pipe has that area of surface-heat transfer is small, and small with fin contacts heat transfer area, the problems such as leeward side has air return limits heat exchanger
The further lifting of heat exchange efficiency, and add air-side flow resistance.
Research shows that the minute yardstick augmentation of heat transfer effect of microchannel can significantly lift the efficiency of heat exchanger, and microchannel aluminium flat conduit is in vapour
Successful Application on car air-conditioning demonstrates this point.But because aluminium fusing point is relatively low, corrosion resistance is poor, it is difficult to adapt to high humility,
The working environment of high-temperature, therefore, it is difficult to be applied on the common equipments such as domestic air conditioning, fan coil and gas heater.If can be real
The micro-channel flat of existing copper pipe, substitutes the round copper pipe of original equipment, it is possible to realize the lifting of heat exchanger performance.It is existing on the market
Copper flat tube is simply directly flattened by pipe and formed, and the effect without microchannel enhanced heat transfer.
Found by the retrieval to prior art, Chinese patent literature CN104654877A, open (bulletin) day 2015.05.27,
A kind of condenser flat tube and condenser are disclosed, the condenser flat tube is integrally formed, rebate is provided with inside condenser flat tube, it is circuitous
The highs and lows in the portion of returning are contacted with condenser flat tube inwall, and condenser flat tube is separated out into multiple passages by rebate.
Folding and forming technique is more complicated in the invention, while welding position is more, easily forms rosin joint to cause each several part bearing capacity not
Uniformly occurs fluid leakage.
The content of the invention
The present invention is directed to deficiencies of the prior art, it is proposed that a kind of S types fold heat exchange flat tube, it is possible to increase family expenses
The heat exchange efficiency of the heat transmission equipments such as air-conditioning, reduces material usage, reduces cost.
The present invention is achieved by the following technical solutions,
The present invention includes：Be integrally formed the first side wall being sequentially connected, second sidewall, the 3rd side wall, internal rib, the 4th side wall,
5th side wall and the 6th side wall, wherein：The first side wall and the 3rd side wall are parallel, and the 4th side wall and the 6th side wall are parallel, second sidewall
It is bilateral symmetry with the 5th side wall, internal rib is that incline structure connects the 3rd side wall and the 4th side wall；
The starting point of the first side wall is fixedly connected on the corner of internal rib and the 4th side wall；
The terminal of the 6th side wall is fixedly connected on the corner of internal rib and the 3rd side wall.
Technique effect
Compared with prior art, the present invention substitutes round copper pipe with copper heat exchange flat tube, reduces wind collateral resistance, increases heat exchange
Area, while overall performance is lifted, reduces copper material consumption；And use roll squeezer to fold the work for being integrally formed, being welded and fixed
Skill can not only ensure the uniformity of heat exchange flat tube overall construction intensity relative to conventional extrusion, and can simplify technique,
Equipment investment is reduced, production cost is reduced.
