Problems solved by technology

[0002] Aluminum heat exchanger is a common device in production and life. Traditional heat exchangers (radiators, evaporators, etc.) are usually made by casting, stamping and welding. There are defects such as mismatch between internal volume and external area, heavy mass, low conductivity, incomplete heat exchange, etc.

Embodiment 1

[0007] Example 1: Manufacturing of M12 Radiator

[0008] 1. Cutting and punching. The slab material AL state Y standard plate is 1200×2500mm, the difference between the same plate is less than 0.015mm, the blanking size is 158×140×3mm, and the inflation port is punched out by a 15T punch.

[0009] 2. Clean and dry. Wash off the oxide film on the surface with a boiling alkaline solution, rinse it in a boiling clear water tank, put it in a 25KW continuous furnace, and dry it at 250°C.

[0010] 3. Printing. Print the deformed circuit according to the requirements of the design drawings. The blocking agent for printing is a carbide that is neutral, extrudable at high temperature, and has no residue. It is preferably a graphite matrix, and it can also be a similar substance.

[0011] 4. Heating. Place the aluminum plate in a 75KW continuous furnace for heating, and the holding time is 15min / mm (calculated by thickness).

[0012] 5. Hot rolling. The heated aluminum plate group...

Abstract

The invention provides a method for manufacturing an Al-Al composite inflation-typed pipeline plate, comprising the steps as follows: a. blanking and punching; b. cleaning and drying; c. printing; d. heating; e. hot rolling; f. cold rolling; g. cleaning; h. annealing; i. inflating; j. marking, shearing and punching; k. welding connecting pipe; l. whole detecting, etc. The composite aluminium pipeline plate processed by the method can increase or reduce the proportion of the internal chamber and the heat exchanging surface in extremely large range, and freely changes the geometrical shape, diameter and volume of the pipeline. The component is completely a whole and has high heat transfer rate and extremely small temperature difference of the medium and the heat exchanging surface. Compared with the traditional heat exchanger, the Al-Al composite inflation-typed pipeline plate has the supreme characteristic that the working pressure endurance value is large and generally keeps at 30kgf/cm<2> for long-term operation. The Al-Al composite inflation-typed pipeline plate has wide application and can be used in internal-heat type or external-heat type and is an extremely good exhaust-reducing and energy-saving product.

Description

technical field [0001] The invention relates to the field of aluminum product processing, in particular to a method for manufacturing an aluminum-aluminum composite inflatable pipeline plate. Background technique [0002] Aluminum heat exchanger is a common device in production and life.
