Abstract
The invention discloses a novel refrigeration evaporator vulcanization production technology which comprises evaporator aluminum pipes and an aluminum plate and comprises the following steps: (1) covering the upper surface of the aluminum plate with a layer of heat-conducting glue, and dip-coating the outer surface of each evaporator aluminum pipe with an anticorrosive coating; (2) press-forming a plurality of grooves matched with the evaporator aluminum pipes in the aluminum plate through a press machine; (3) drying the coatings on the evaporator aluminum pipes and then performing vulcanization treatment; (4) placing the evaporator aluminum pipes in the grooves, and bonding and fixing the evaporator aluminum pipes to the aluminum plate covered with a heat-conducting glue film by heating and vulcanization; and (5) finally, applying an anticorrosive coating material to the contact parts of the evaporator aluminum pipes and the aluminum plate, and performing constant-temperature drying. The technology overcomes defects in the prior art; the grooves are formed in the surfaces of the aluminum plate to hold the evaporator aluminum pipes so as to enhance the bonding firmness between the aluminum plate and the evaporator aluminum pipes; meanwhile, the anticorrosive coating material is applied to the contact parts of the evaporator aluminum pipes and the aluminum plate so as to effectively avoid a spot corrosion phenomenon at the joints of the evaporator aluminum pipes and the aluminum plate; and the technology is lower in cost than an anodic oxidation technology which is harmful to the environment, and meets the environmental protection requirement.

Technical field
The present invention relates to refrigeration technology field, particularly belong to a kind of novel refrigeration evaporator sulfuration production technology.
Background technology
Plate-type evaporator is the main heat-exchanger rig in refrigeration system, its effect be make the liquid refrigerant of low-temp low-pressure within it rapidly evaporation (boiling) be steam, absorbing the heat of cooled material, making the temperature of cold preservation (freezing) material decline thus reaching the purpose of refrigeration. Vaporizer is mainly made up of metal tube and metallic plate combined process, aluminum pipe and aluminium sheet is directly bondd. Existing this mode bonding method, the spot corrosion phenomenon that tube sheet junction exists, loosening easily occur in plate face and aluminum pipe time, and connect firm not.
Summary of the invention
It is an object of the invention to provide a kind of novel refrigeration evaporator sulfuration production technology, overcome the deficiencies in the prior art, mode aluminum pipe is carried out by groove will be arranged in vaporizer surface of aluminum plate, increase firm pasting between aluminium sheet and aluminum pipe, coat anticorrosive paint in aluminum pipe and aluminium sheet contact position simultaneously, efficiently avoid the spot corrosion phenomenon that tube sheet junction exists, cost, lower than the anode oxidation process that environment has harm, has reached environmental requirement.
The technical solution used in the present invention is as follows:
A kind of novel refrigeration evaporator sulfuration production technology, it includes vaporizer aluminum pipe and aluminium sheet,
(1) lid layer heat-conducting glue is covered at aluminium sheet upper surface, and at vaporizer one layer of anticorrosive paint layer of aluminum pipe outer surface dip-coating;
(2) aluminium sheet will extrude multiple groove coordinated with aluminum pipe by forcing press,
(3) vulcanizing treatment is carried out after being dried by the dope layer on vaporizer aluminum pipe,
(4) the heated bonding by Vulcanization of aluminium sheet being positioned in groove by vaporizer aluminum pipe and cover conductive adhesive film is fixed;
(5) finally anticorrosive paint constant temperature drying is coated in vaporizer aluminum pipe and aluminium sheet contact position.
Described heat-conducting glue is made up of the component of following weight portion: class Graphene boron nitride nanosheet, firming agent, halogen-free epoxy resin, heat filling, solvent are hybridly prepared into.
Aluminum pipe is only heated by (5th) described step, and heating and temperature control is at 80-120 degree.
Compared with the prior art, beneficial effects of the present invention is as follows:
The present invention carrys out mode aluminum pipe by arranging groove in vaporizer surface of aluminum plate, increase firm pasting between aluminium sheet and aluminum pipe, coat anticorrosive paint in aluminum pipe and aluminium sheet contact position simultaneously, efficiently avoid the spot corrosion phenomenon that tube sheet junction exists, cost, lower than the anode oxidation process that environment has harm, has reached environmental requirement.
