Abstract
The utility model provides a folding two-channel heat exchanger flat tube, which can be widely used for heat exchangers such as domestic air conditioners, warm air blowers in vehicle air conditioners, water tanks and evaporators. The function of the flat tube manufactured through the process is the same with the function of an ordinary high-frequency welded tube or stretching flat tube, but the flat tube belongs to a novel process structure. The flat tube can be formed by processing a piece of aluminum sheet under the normal temperature and the normal state, and the inner folded edge of the flat tube is in an opposed blade shape. The flat tube has higher reliability, so that the durability of the heat exchangers is better. The flat tube can replace the ordinary high-frequency welded tube or stretching flat tube at present.
Description
Technical field
The utility model relates to a kind of collapsible heat exchanger flat tube, can be widely used in heat exchangers such as automobile warm-air, water tank, evaporimeter.
Background technology
The ratio-frequency welding flat tube is seen accompanying drawing 1 at present.Present problem is the solder joint of high-frequency tube, with the assembling of other parts the time, causes scratch and damage easily, influences product percent of pass and reliability after the soldering.And the high-frequency tube technological requirement is higher, and yield rate is limited, and mould development and life-span and equipment investment repayment are all brought than hang-up.The stretching flat tube also exists die cost big, the problem that yield rate is low.
The utility model content
The purpose of the utility model is to provide a kind of collapsible 2 channel heat exchanger flat tubes, and such flat tube configuration is seen accompanying drawing 2.It has avoided the high-frequency tube yield rate not high, and brazing product technology is unstable.
By an aluminum alloy plate materials Bending Processing.Adopt soldering synthetic at Al-alloy plate joint; Flanging is splayed configuration (Fig. 2 reference numeral sign: 1) in the heat exchanger flat tube; Extend to the tube wall inboard, forming a width is 10mm～40mm, highly is the folding flat tube of 1mm～3mm; Cold-producing medium or cooling fluid can flow freely in this flat tube, carry out dynamical heat exchange.
This patent has been invented a kind of folding flat tube of new structure, substitutes ratio-frequency welded tube and stretching flat tube, has increased the reliability of heat exchanger, effectively improves yield rate after the soldering, the reduction spillage of material.
Description of drawings
Fig. 1 is a common ratio-frequency welding flat tube sketch map commonly used at present
The collapsible 2 channel heat exchanger flat tube schematic cross-sections of Fig. 2 the utility model explained hereafter
The reference numeral sign: flanging is splayed configuration in 1 flat tube
Fig. 3～Fig. 7 is the different shape sketch map in the flat tube process
The specific embodiment
The utility model is to implement like this:
Step 1. is converted into Fig. 3 with bender with the two ends of opening and closing gold aluminium sheet and shows shape.
Step 2. is with the inward at both ends bending, like Fig. 4 shape.
Step 3. inward at both ends bending back forms shown in Figure 5.
Step 4. is again with the inward at both ends bending, and is as shown in Figure 6.
Form shape shown in Figure 7 after step 5. bends inwards, comprise heat exchanger flat tube finished product and shaping.
This processing method can be carried out under the normal temperature normality.
Claims (2)
1. collapsible 2 channel heat exchanger flat tubes is characterized in that: this flat tube is formed by opening and closing gold aluminium sheet Bending Processing.
2. collapsible heat exchanger flat tube according to claim 1 is characterized in that: a) flanging is splayed configuration in this flat tube, extends to the tube wall inboard, and b) to be of a size of width be 10mm～40mm to this flat tube, highly is 1mm～3mm.
