Detailed description of the invention
Further describe by reference to the accompanying drawings:
As shown in Figure 1 to 4, a kind of truck automobile air conditioner parallel flow condenser, is made up of at least heat exchange first module I, heat exchange second unit II, heat exchange the 3rd unit III, wherein between heat exchange unit, is separated by dividing plate 4; Heat exchange unit is by left collector tube 1, right liquid collecting tube 7, the wave wing band 3 of some porous flat pipes 2 and blind window forms, at the upright left and right collector tube of arranging and the right angle connecting portion of porous flat pipe 2, punching has the slotted hole that porous flat pipe 2 is installed, in the time of assembling, porous flat pipe 2 embeds left collector tube 1 and right liquid collecting tube 7, the wave wing band 3 of corresponding layout blind window between many porous flat pipes 2, left and right collector tube adopts the circular pipe type structure of same diameter, there is be convenient to processing and assembling simple in structure, production technology is simple, the feature that cost is low.The inner dividing plate 4 that right quantity is set in the collector tube of left and right, is arranged in and imports and exports on jockey; Heat exchange first module I is 1.3 ~ 1.5 with heat exchange second unit II internal capacity ratio, and heat exchange second unit II is 1.1 ~ 1.3 with heat exchange the 3rd unit III internal capacity ratio; Wherein the height dimension of porous flat pipe 2 is 1.8mm～2.5mm, the height dimension of the wave wing band 3 of blind window is 7.5mm～9mm, the material thickness of the wave wing band 3 of blind window is 0.07mm～0.1mm, and condenser thickness is 19mm～26mm, and collector tube outer dia is Φ 24 ~ Φ 30 mm.Wherein bowl formula blanking cover 6 is arranged in collector tube end, and the thickness of blanking cover 6 materials is 1.4mm, and this structure condenser structure is simple, manufactures processing and simple for assembly process, and cost is low, and high strength is applicable to lorry air-conditioning system condenser and uses.
