Abstract
A machine oil cooler of built-in plate-fines type composed of plate fins, core plates, heat radiating screen and joint, which are all made of aluminium alloy or composite aluminium materials. Said cooler is made by advanced soldering technique. Its advantages are light weight, high heat radiating performance, low cost and no environmental pollution.
Description
The present invention is the built-in plate-fins machine oil cooler made of aluminium that is used to cool off gear box oil and hydraulic oil in the heat exchanger system.
At present, domestic used built-in plate-fins oil cooler all is a plate-fin stainless steel oil cooler.Plate-fin stainless steel oil cooler mainly adopts stainless steel as raw material, forms with 800 ℃ of high-temperature soldering in vacuum drying oven.The following shortcoming that it exists: the one, because raw material adopt stainless steel (1Cr18Ni9), the big (density p=7.9g/cm of quality
2), be 2.2 times of aluminum machine cooler of same size, as: the stainless steel machine cooler weight of 292H7 is 1.2Kg, and that aluminum only is 525g, and in the plastic-aluminum water radiator that this develops afterwards, the intensity of plastics hydroecium can't be born the oil cooler of weight like this at all; The 2nd, thermal conductivity is low, and thermal conductivity factor λ=14.7W/m. ℃, less than 1/10 of aluminium thermal conductivity factor; Cost height in addition, heat dispersion is poor.
The purpose of this invention is to provide a kind of in light weightly, cost is low, perfect heat-dissipating, the built-in plate-fins machine oil cooler made of aluminium of non-environmental-pollution.
The present invention is to be raw material with resourceful aluminium, utilize the good plasticity and the thermal conductance of aluminium, give full play to the characteristics that it is in light weight, cost is low, after technical process such as punching press, machine-shaping, cleaning, assembling, in NOCOLOK soldering oven or vacuum drying oven, once be welded, produce energy-efficient built-in plate-fins machine oil cooler made of aluminium.
Introduce the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 is a typical structure I schematic diagram of the present invention
Fig. 2 is a typical structure II schematic diagram of the present invention
The present invention replaces former stainless steel to manufacture the built-in plate-fins oil cooler with aluminium, promptly (the built-in plate-fins oil cooler that has does not contain radiator-grid by fin (1), chip (2), radiator-grid (3), as shown in Figure 2), the built-in plate-fins oil cooler formed such as joint (4), the material of its fin (1), chip (2), radiator-grid (3), joint (4) is aluminium alloy and compound aluminium product.The above-mentioned various parts that utilize the superperformance of aluminium to be processed into, through clean, oven dry, assembling, soldering then, be processed into built-in plate-fins machine oil cooler made of aluminium.Selecting for use of aluminium alloy and compound aluminium product can be selected according to the soldering processes and the different of equipment of adopting, and also can determine soldering processes and equipment according to the aluminium alloy and the compound aluminium product that adopt.As: when adopting the NOCOLOK soldering processes, the material of chip (2) can adopt 4343/3003/4343, and the material of the stiffener in the chip (2) can adopt 4343/3003/313, brazing flux K
4～6ALF
1～3When adopting vacuum welding technology, the material of chip (2) can adopt 4045/3003/4045, and the material of the stiffener in the chip (2) can adopt 4045/3003/3003.In these two kinds of soldering processes kinds, the material of the radiator-grid (3) in fin (1) and the fin all can adopt LF21-M, and the material of joint (4) all can adopt K70A.
Be that concrete production technology is an enforcement example below:
The rolling of fin (1):, utilize and roll wing machine rolling fin (1) according to the requirement of drawing and technology.
The rolling of radiator-grid (3):, utilize net roller rolling radiator-grid (3) according to drawing and technological requirement.
The punching out of chip (2): according to the requirement of drawing and technology, special-purpose perforating die, finishing die, blanking die and the sizing die etc. of design chips (2), punching out chip (2).
The turning of joint (4): turning joint (4) guarantees the inside and outside silk that drawing requires.
Cleaning, drying: the part of processing is successively placed in three rinse baths and cleans.In first rinse bath, concentration of lotion is 3～3.5%, and temperature is 60～70 ℃, detects after lasting 3～5 minutes; In second rinse bath, serviceability temperature is that 60～70 ℃ clear water cleans taking-up in 2 minutes; In the 3rd rinse bath, in the clear water of normal temperature, rinse well.The drying baker of parts after cleaning up being put into the water drop after clean equably 170 ℃ is dried.
Assembling:, guarantee that product meets the requirement of drawing and technology with special-purpose harness, anchor clamps assembling, clamping.
Welding: use NOCOLOK soldering oven or vacuum drying oven to weld in different welding atmospheres, welding temperature is 595～605 ℃.In the NOCOLOK soldering, speed of welding is 500～600mm/min, and nitrogen flow is 50～70m
3/ h; In the vacuum welding, vacuum is 8 * 10 in the stove
-5Pa, be 4～5 hours/stove weld interval.
Pressure testing: charge into the compressed air of 1.5MPa in the machine cooler, pressurize 3min should not have any leakage and damage.
Dry up, check, pack warehouse-in.
We are customized according to client's demand for the profile of product, sheet number, annex etc.Install after the user buys and to use.
The present invention is as raw material with aluminium, make full use of the mineral resources of China's abundant, the policy that had both met national development aluminum heat exchanger, the actual conditions that also meet Mineral Resources in China, the a large amount of precious resource of more national saving the most important thing is to make that the performance of oil cooler has obtained improving greatly, and weight has reduced by 1/2, cost has descended 10～20%, satisfied international radiator with aluminium for copper, to mould user demand for the development trend of copper.Because the present invention adopts advanced welding procedure, use no brazing flux welding or do not have the welding of chlorine brazing flux simultaneously, the subsequent treatment after the solderless, non-environmental-pollution meets the national environmental protection policy.Therefore, in light weight, the incomparable advantages of built-in plate-fins stainless steel oil cooler such as cost is low, perfect heat-dissipating, non-environmental-pollution that built-in plate-fins machine oil cooler made of aluminium of the present invention has, in the use, can compare favourably with built-in plate-fins stainless steel oil cooler, on performance, be far superior to it again.And cost has obtained tangible decline, for oil cooler family has increased new member, finally will become the substitute of built-in plate-fins stainless steel oil cooler.
