Further, described inside and outside first quarter moon strikes out template and adopts the aluminium sheet punch forming respectively, and its outer surface is coated with the welding material composite surface.
Further, described in first quarter moon strike out template and be provided with to adapt to and cooperate and weld the slotted hole sequence of fixing with flat tube, outer first quarter moon strikes out template and is provided with the mounting bracket that is used to connect the pressing plate joint of air-conditioning system and is used for fixing condenser.
Further, it is a plurality of chambers and then the partition that changes the working medium flow direction that described header is provided with the header sealed separation inside, and partition adopts outer surface to be coated with welding material and the thick double-sided composite plate punch forming of 1.5mm.
Further, described flat tube is the micro-channel flat of aperture less than 1mm, and its section is flat oblong, section appearance and size is thick * wide be 1.4mm * 12mm, section is provided with 15 circular holes.
Further, described flat tube adjacent shaft distance is 6.4mm.
Further, described condenser includes the radiating fin that is arranged between the adjacent flat tube, and radiating fin has shutter and fixing with the flat tube welding respectively.
Further, described radiating fin adopts clad aluminum foil to make, and its two sides all is coated with weld material layer.
Further, described radiating fin to the spacing of header smaller or equal to 5mm.
Further, the integral braze-welded moulding of described header, flat tube and radiating fin.
The utility model compared with prior art, its beneficial effect is:
1, header adopts inside and outside first quarter moon to strike out template to fasten and to form, substituted the round multiple tube of high frequency, avoid outsourcing, shorten the production cycle, and then reduced cost;
2, core body is thin, and weight saving is tending towards the lightweight development;
3, the flat tube cross section increases, and passage dwindles, and then reduces and use refrigeration working medium, is beneficial to environmental protection;
4, be more conducive to system high pressure power and impact, bearing capacity is stronger.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
