Abstract
The utility model provides a folding eight-channel flat pipe with reinforced pipe end strength. Two layers of materials are arranged at each pipe end, the flat pipe can be formed by bending and processing an aluminum alloy plate for multiple times at a normal temperature, the strength of the flat pipe is higher than that of a flat pipe with a layer of materials at each of two ends, and refrigerant or cooling liquid is capable of freely flowing in the flat pipe to realize high-efficiency heat exchange. The folding eight-channel flat pipe is simple in structure, convenient in manufacture and low in cost, and can be used for various types of vehicles such as a saloon car, a microcar, a bus, a minibus and the like and heat exchangers for household air conditioners.
Description
Technical field
The utility model relates to the collapsible 8 passage flat tubes of a kind of double-deck pipe end, can be widely used in heat exchangers such as automobile condenser, water tank, charge air cooler.
Background technology
Multichannel collapsible 8 passage flat tubes are that two ends have only 1 layer material at present, and such flat tube is seen accompanying drawing 1.Present problem is that the two ends intensity of flat tube is on the low side, with the welding of other parts the time, causes easily and breaks and damage.
The utility model content
The purpose of this utility model is to provide a kind of double-deck pipe end collapsible 8 passage flat tubes, and such flat tube configuration has overcome the collapsible 8 passage flat tubes of individual layer pipe end, and two ends intensity is on the low side, with other parts welding the time, causes the defective of breaking and damaging easily.
This flat tube respectively keeps 1mm～3mm (can form the flat tube two ends of reinforcement) by opening and closing gold aluminium sheet two ends, and begins Bending Processing from here and form, and pipe end is a double-decker.The gap is less than 0.05mm between 2 layer materials, and number of channels is eight, and the width of this micro-channel flat is 10mm～30mm, highly is 1mm～3mm.
Cold-producing medium or cooling fluid can flow freely in this flat tube, carry out dynamical heat exchange.
Description of drawings
Fig. 1 is common collapsible 8 passage flat tube schematic diagrames commonly used at present
The collapsible 8 passage flat tube cross sections signal of the double-deck pipe end of Fig. 2 the utility model explained hereafter
Fig. 3～Fig. 7 is the different shape 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, as Fig. 4 shape.
Step 3. inward at both ends bending back forms appearance shown in Figure 5.
Step 4. is again with the inward at both ends bending, as shown in Figure 6.
Step 5. back that bends inwards forms shape shown in Figure 7, Here it is flat tube finished product.
This processing method can be carried out under the normal temperature normality.
Claims (2)
1. collapsible 8 passage flat tubes of strengthening pipe end intensity is characterized in that: this flat tube is formed by opening and closing gold aluminium sheet Bending Processing, and pipe end is a double-decker.
2. a kind of collapsible 8 passage flat tubes of strengthening pipe end intensity according to claim 1, it is characterized in that: the gap is less than 0.05mm between 2 layer materials, and number of channels is eight, and the width of this micro-channel flat is 10mm～30mm, highly is 1mm～3mm.
