Abstract
The invention relates to the technical field of refrigerator refrigeration and particularly belongs to a refrigeration evaporator production process. An aluminum pipe and an aluminum board are included. The refrigeration evaporator production process comprises the following steps that (1) a layer of sulfuration film covers the upper surface of the aluminum board, specifically, the sulfuration film is prepared from, by weight, 10-20 parts of ethylene-vinyl acetate copolymer, 20-50 parts of polyethylene, 1-10 parts of graphene boron nitride nanosheets, 1-3 parts of curing agents, 10-40 parts of halogen-free epoxy resin, 2-4 parts of thermal conducting filler and 10-20 parts of solvent through mixing, and then the aluminum pipe is subjected to anodic oxidation; (2) the aluminum pipe subjected to anodic oxidation is bent to be in a coiled shape through a pipe bending machine; (3) the aluminum pipe bent to be in the coiled shape is flattened through a flattening machine; and (4) the flattened aluminum pipe is installed in a sulfuration mold, then the aluminum board is placed on the flattened aluminum pipe, a sulfuration machine carries out pressurization and heating, and thus the aluminum board is bonded onto the aluminum pipe. After the portion, needing sulfuration, of the aluminum pipe is flattened, effective bonding is carried out through the sulfuration film under the action of pressurization and heating of the sulfuration machine.
Description
Technical field
The present invention relates to refrigeration for refrigerator technical field, particularly belongs to a kind of refrigeration evaporator production technology.
Background technology
Refrigerator cold-storage evaporimeter is exactly the plate-tube type evaporator often said, it is the main heat exchange dress in refrigerator refrigeration system
Put, its effect is that the liquid refrigerant for making low-temp low-pressure is evaporated in which rapidly（Boiling）For steam, cooled material is absorbed
Heat, make refrigeration（Freezing）The temperature drop of material is so as to reaching the purpose of refrigeration.The composition of plate pipe evaporator is by inciting somebody to action
It is connected together by melt viscosity between aluminum pipe and aluminium sheet, the production technology of prior art is not due to being flattened just to enter to aluminum pipe
Row bonding, so that cause the insecure of bonding.
The content of the invention
It is an object of the invention to provide a kind of refrigeration evaporator production technology, overcomes the deficiencies in the prior art, passes through
After first needing bonding by Vulcanization position to flatten to aluminum pipe, then enter using sulfide film and under the heating pressurization of vulcanizer
Row effectively bonds.
The technical solution used in the present invention is as follows：
A kind of refrigeration evaporator production technology, it includes aluminum pipe and aluminium sheet,
（1）One layer of sulfide film is covered in aluminium sheet upper surface, and aluminum pipe is carried out into anodic oxidation；
（2）Aluminum pipe after anodic oxidation is curved into snakelike shape by bending machine；
（3）The aluminum pipe for curving snakelike shape is flattened by flatting mill；
（4）Aluminum pipe after flattening is installed in the vulcanizing mold of vulcanizing equipment, then aluminium sheet is placed on the aluminum pipe after flattening, led to
The pressurization of over cure machine, heating, aluminium sheet is bonded on aluminum pipe.
The sulfide film is made up of the component of following weight portion：The sulfide film is made up of the component of following weight portion：Second
Alkene-acetate ethylene copolymer 10-20 parts, polyethylene 20-50 parts, class Graphene boron nitride nanosheet 1-10 parts, curing agent 1-3
Part, halogen-free epoxy resin 10-40 parts, heat filling 2-4 parts, solvent 10-20 parts are hybridly prepared into.
Compared with the prior art, beneficial effects of the present invention are as follows：
The present invention by anodic oxidation first to aluminum pipe after, after the oxide-film that aluminum tube surfaces form fine and close, by aluminum pipe and aluminium
The sulfuration processing of plate, cost have reached environmental requirement less than the mopping technique for having harm to environment.
Specific embodiment
A kind of refrigeration evaporator production technology, it includes aluminum pipe and aluminium sheet,
（1）One layer of sulfide film is covered in aluminium sheet upper surface, described sulfide film is made up of the component of following weight portion：The sulfuration
Film is made up of the component of following weight portion：Ethene-acetate ethylene copolymer 10-20 parts, polyethylene 20-50 parts, class Graphene
Boron nitride nanosheet 1-10 parts, curing agent 1-3 parts, halogen-free epoxy resin 10-40 parts, heat filling 2-4 parts, solvent 10-20 parts
It is hybridly prepared into.Aluminum pipe is carried out into anodic oxidation again；
（2）Aluminum pipe after anodic oxidation is curved into snakelike shape by bending machine；
（3）The aluminum pipe for curving snakelike shape is flattened by flatting mill；
（4）Aluminum pipe after flattening is installed in the vulcanizing mold of vulcanizing equipment, then aluminium sheet is placed on the aluminum pipe after flattening, led to
The pressurization of over cure machine, heating, aluminium sheet is bonded on aluminum pipe.
