Abstract
A heat exchanger gas (liquid) tube for an automobile air conditioner evaporator comprises a closed tube cavity. Sheet material is bent and connected at the end portion to form the closed tube cavity. The heat exchanger gas (liquid) collecting tube for the automobile air conditioner evaporator is characterized in that the junctions of two ends of the sheet material are respectively bent to form two parts combined in parallel, and a connecting gap is formed between the two parts combined in parallel. According to the heat exchanger gas (liquid) collecting tube for the automobile air conditioner evaporator, sheet material contact area at the position of a welding seam is relatively large, welding process is easy, welding-on of the welding seam is ensured even if slight deformation exists, and product percent of pass and compression resistance of the tube are improved.
Description
Technical field
The utility model relates to automobile air-conditioning evaporator, particularly relates to a kind of heat exchanger collection gas/liquid pipe.
Background technology
At present, automobile air-conditioning evaporator collection gas/liquid pipe is divided into several forms such as extrusion modling section bar, ratio-frequency welding profiles, assembled, punching type.Wherein punching type collection gas/liquid tubular construction is simple, more and more come into one's own, what but punching type collection gas/liquid pipe joint adopted at present is the docking soldering of thickness of slab limit, because thickness of slab is thinner, the weld contact area is less, be subjected to the impact of machining accuracy, welding deformation, the butt welding qualification rate is lower, causes the lower phenomenon of not seam and compression resistance.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, a kind of novel heat exchanger collection gas/liquid pipe that is used for automobile air-conditioning evaporator is proposed, it has increased the contact area of weld, be easy to welding processing, even there is slight deformation also can guarantee the weld seam seam, the qualification rate of welding and the compression resistance of pipe have been improved.
Heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator of the present utility model, bend and form in engaged at end the tube chamber of sealing by sheet material, form respectively the part of two parallel merging in the junction at described sheet material two ends by bending, between these two parallel assembling sections, form one and connect the slit.
Heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator of the present utility model, the cross sectional shape of wherein said heat exchanger collection gas/liquid pipe is roughly rectangular.
Heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator of the present utility model, wherein said connection slit is connected and fixed by welding.
Heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator of the present utility model, solder joint place sheet material contact area is larger, is easy to welding processing, even there is slight deformation also can guarantee the weld seam seam, has improved the qualification rate of welding and the compression resistance of pipe.
Description of drawings
Fig. 1 is the sectional view of the heat exchanger collection gas/liquid pipe that is used for automobile air-conditioning evaporator of utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator of the present utility model is made of the sheet material that symmetry bends, be formed on the rectangle that bending part has fillet, by Reference numeral 2,6,3,5,4 expressions, 2,6 junction bends inwards in the outside respectively in each outside of this rectangle, and the bending place forms respectively the part of two parallel merging, their outer side edges is respectively 1,7, in the middle of this two parallel assembling section, form a slit, add and weld in this slit man-hour, form weld seam 8.
Since larger in weld seam 8 place's sheet material contacts area, be easy to welding processing, even there is slight deformation also can guarantee the weld seam seam, improved the qualification rate of welding and the compression resistance of pipe.
Claims (3)
1. heat exchanger collection gas/liquid pipe that is used for automobile air-conditioning evaporator, bend and form in engaged at end the tube chamber of sealing by sheet material, it is characterized in that, form respectively the part of two parallel merging in the junction at described sheet material two ends by bending, between these two parallel assembling sections, form one and connect the slit.
2. the heat exchanger collection gas/liquid pipe for automobile air-conditioning evaporator according to claim 1 is characterized in that the cross sectional shape of described heat exchanger collection gas/liquid pipe is roughly rectangular.
