Description
[technical field]
The utility model relates to the auto parts machinery technical field, refers more particularly to the automobile air conditioning technology field, and concrete is a kind of full aluminium welded type heat exchanger.
[background technology]
Heat exchanger is mainly used in car heater.The major function of car heater is that driver's cabin is heated, and mist elimination, defrosting for the driver provides good sight line, reduce driver's degree of fatigue, improve traffic safety, simultaneously, and for the personnel that ride provide comfortable environment by bus.
Hydroecium is a vitals that adopts in the heat exchanger; existing heat exchanger is mainly formed (seeing accompanying drawing 1) by hydroecium 11, main leaf 12, backplate 13, fin 14 and flat tube 15; hydroecium 11 wherein, main leaf 12 are punch formings (seeing accompanying drawing 2) respectively; then; combine the welding of the laggard helium protection of core body stove with backplate 13, fin 14, flat tube 15, weld water inlet pipe and water outlet pipe after coming out of the stove again by hand.
Because heat exchanger has multiple model and specification, cause hydroecium 11 and main leaf 12 that multiple model and specification are also arranged, so, hydroecium 11 and main leaf 12 punch forming separately just seem too complicated, not only the grinding tool that will open is many, manufacturing procedure is many, recruitment is many, cause production cost too high, and the gap after causing hydroecium and main leaf being connected such as the draw taper that forms because of punching press, the arc chord angle of bending deformation is wayward, the faying face out-of-flatness, the first-time qualification rate that product is come out of the stove is on the low side, and percent defective is high; In addition, the versatility of this technology is also relatively poor, and the space is significantly improved.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and can omit punch forming process, can increase versatility, reduce production costs, can eliminate simultaneously draw taper and bending deformation that punch forming forms, improve the come out of the stove full aluminium welded type heat exchanger of qualification rate of product.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of full aluminium welded type heat exchanger, contain hydroecium, main leaf, backplate, fin and flat tube, it is characterized in that, hydroecium is by falling the making of " U " font aluminium section, main leaf is made into " U " font, the flat tube perforating die of main leaf is taked general form, and the length of aluminium section water chamber and main leaf can be regulated arbitrarily; The hydroecium of aluminium section and main leaf limit are provided with syndeton, and it forms same plane in conjunction with the back; End face after hydroecium and main leaf combination is provided with blanking cover.
The length of described aluminium section can be regulated.
Can utilize the heat exchanger of the length making all size of aluminium section.
Syndeton on described hydroecium and the main leaf is a joint construction, and hydroecium is connected the both sides, back and respectively forms same plane with main leaf.
Described syndeton is provided with the projection welding point.
Described projection welding point is symmetrical projection welding point.
The good effect of a kind of full aluminium welded type heat exchanger of the utility model is:
(1) changes original stamping forming hydroecium into the employing aluminium section, can in the length range of aluminium section, make the hydroecium of random length, avoided the independent stamping forming operation of hydroecium and main leaf palpus, the gap of having avoided the arc chord angle because of draw taper that punching press forms, bending deformation to cause, the flat tube perforating die is general, can produce the heat exchanger of all lengths specification, and the planarization of hydroecium and main leaf faying face is better, has improved the qualification rate that product is come out of the stove.
(2) because of having adopted aluminium section to make hydroecium, with the complete two ends of blanking cover, and adopted the projection welding point on the joint construction of hydroecium and main leaf, made the joint face of hydroecium more firm, more smooth, production cost is significantly reduced.
(3) better because of the planarization of hydroecium and main leaf faying face, created good design condition for reaching in the stove no leak source, thereby production efficiency is higher, and the heat exchanger of production can be widely used in products such as radiator, charge air cooler, evaporimeter, heater, condenser.
(4) increased substantially the qualification rate of product, economic benefit is obvious; The disposable qualification rate of product rises to 98% by 80%, by 200,000 calculating of annual capacity power, can increase by 3.6 ten thousand of finished products, calculates by every 0.5Kg material, can save 180 tons of aluminiums, is worth about about 7,200,000 yuan.
