There are the following problems in the manufacturing for current vertical current radiator:
1, because radiator core body main leaf is long, radiating tube is many, and belt is intensive, the not full uneven defectiveness of weld seam, and molten zoning also happens occasionally, and core body solder yield is on average about 83%.
2, after radiator core body soldering, main leaf bending deformation is many, accounts for 40%.
3, hydroecium and core body main piece press-fit be engaged after leak more after airtight inspection, accounting more than 30%, scraps and reaches 7%.
4, the product appearance after undercut of doing over again is ugly, product degradation level mark-down sale.
5, productivity ratio is low, and cost is higher.
Prior art: a soldering qualification rate 83%, product rejection rate 7%, loss due to spoiled work 12.6 ten thousand yuan;
The utility model: a soldering qualification rate 97%, product rejection rate 0.5%, loss due to spoiled work 0.9 ten thousand yuan.
Summary of the invention
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the automobile vertical current radiator that a kind of quality is high, production cost is low is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of automobile vertical current radiator, comprise upper tank, lower header, radiator core body and rubber gasket, described radiator core body be connected to upper tank, lower header and between, described rubber gasket is located at the junction of radiator core body and upper lower header, described radiator core body comprises main leaf, radiating tube, heat-radiation belt and side plate, described main leaf, radiating tube, heat-radiation belt and side plate are integral by brazing, and described rubber gasket is ellipsoidal structure.

Described radiator core body is press-fited by rubber gasket and upper tank, lower header and is connected.
Described main leaf is provided with coat, and the material of described coat is 4045 aluminium base solders.
Build-up tolerance between described main leaf and radiating tube is 0.08mm.
When described main leaf, radiating tube, heat-radiation belt and side plate are by brazing, the soldering oven air curtain curtain steel disc adopted is 0.3mm.
Compared with prior art, the utility model has the following advantages:
1, the coat on the utility model main leaf adopts 4045 aluminium base solders, and radiator core body weld seam after soldering is evenly full, and molten zoning no longer occurs, and one time solder yield is promoted to more than 97%;
2, after product soldering, main leaf buckling phenomenon has change greatly, and main leaf bends accounting and is down to 6% by 40%;
3, the utility model rubber gasket is ellipsoidal structure, is placed on main leaf groove not sideslip placed in the middle, and hydroecium press-fits to leak is down to about 3% by 30%, scraps and is down to 0.5% by 7%, and product quality and product appearance have had and significantly promote;
4, greatly production cost is reduced;
5, with annual output 10000, every platform 180 yuan, by prior art and economic efficiency contrast of the present utility model:

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Figure 1-Figure 2, a kind of automobile vertical current radiator, comprise upper tank 1, lower header 7, radiator core body and rubber gasket 2, radiator core body be connected to upper tank 1, lower header 7 and between, rubber gasket 2 is located at the junction of radiator core body and upper lower header.Radiator core body comprises main leaf 3, radiating tube 4, heat-radiation belt 5 and side plate 6, main leaf 3, radiating tube 4, heat-radiation belt 5 and side plate 6 is integral by brazing, main leaf 3 is affixed with radiating tube 4 soldering, radiating tube 4 is affixed with heat-radiation belt 5 soldering, side plate 6 and heat-radiation belt 5 and main leaf 3 soldering affixed, whole radiator core body is press-fited by rubber gasket 2 and upper tank 1, lower header 7 and is connected.Main leaf 3 is provided with the groove for installing rubber gasket 2.
In the present embodiment, rubber gasket 2 is ellipsoidal structure, as shown in Figure 4.Existing rubber gasket as shown in Figure 3, is placed on main leaf groove easily sideslip not placed in the middle, leakiness after press-fiting with hydroecium.And in the utility model, sealing gasket is oval, be placed on main leaf groove not sideslip placed in the middle, as shown in Figure 2, after using and improving, sealing gasket hydroecium press-fits to leak being down to about 3% more by 30%, and scrap and be down to 0.5% by 7%, product quality and product appearance U.S.A have had and significantly promote.
Main leaf 3 is provided with coat, and the material of coat is the aluminium base solder (brazed aluminum alloy) of alloy designations 4045.Existing coat adopts alloy designations to be the aluminium base solder of 4343, and brazing temperature is high dispels the heat when 613 degree of solderings with the generation of corrode phenomenon, and main leaf welds not full uneven defect with radiating tube.This is that heat-radiation belt material 0.08mm is thick because main leaf material 1.7mm is thick, and coat material 4343 does not very melt at this warm area coating material, and discontented weld gap filled by solder.Reduce temperature as continued and then solve heat-radiation belt corrode phenomenon, but main leaf welds with radiating tube and Lou significantly promotes.Adopt 4045 coating materials, due to brazing temperature lower than 608 degree time, main leaf weld with radiating tube full evenly and heat-radiation belt does not have corrode phenomenon, product core body solder yield is promoted to more than 97%.
Fit-up gap tolerance between main leaf 3 and radiating tube 4 is 0.08mm, eliminates soldering and because of the hidden danger such as the large main leaf of assembly clearance large main leaf soldering stress is yielding.
When main leaf 3, radiating tube 4, heat-radiation belt 5 and side plate 6 is by brazing, the soldering oven air curtain curtain stainless steel substrates adopted is replaced by 0.3mm by 0.5mm, and number ratio originally reduced 1/5th.Vertical current radiator length of a film, entering soldering oven apoplexy curtain firmly, the large resistance of density is large, easily makes core body main piece bending be out of shape probability and increases.Through practice test, after above measure, after product soldering, main leaf buckling phenomenon has greatly change, main leaf bends accounting and be down to 6% by 40%.
