Abstract
The utility model relates to a wire pipe type evaporator which comprises evaporating pipe slices which are at least composed of one multiple circuitous evaporating pipe. A plurality of heat radiation wires which are arranged at both sides of each evaporating pipe and is welded with the evaporating pipe are arranged on each evaporating pipe slice, which enhances the heat radiation. The outer surface of the evaporator is coated with a protective layer which can prevent the evaporator from being rusted. Before refrigerant is arranged in the evaporating pipe, when the evaporating pipe is stored and transported, nitrogen gas is arranged in the pipe, which can prevent water vapor from entering the pipe. The end head of the heat radiation wire is made into a smooth shape, which can avoid point discharge which can cause the phenomenon that the protective layer can not be sprayed when the surface is sprayed with a protective layer by static electricity. The utility model is suitable for being used on an electric refrigerator, an electric freezing cabinet, a show cabinet and a cocktail cabinet with low temperature.
Description
The utility model relates to the evaporimeter that a kind of compression refrigerating apparatus is used, particularly a kind of wire-and-tube evaporator.
In the used evaporimeter of compression refrigerating apparatus, be to cool off by refrigerant compression, the evaporation heat absorption of expanding is then lowered the temperature, common evaporimeter has inflation type and tube-sheet type, its shortcoming is that aluminium sheet is whole, and heat transfer efficiency is poor, and evaporimeter is the insulation interlayer that foams in refrigerator body or place casing, heat-conducting effect is poorer, and maintenance is inconvenient; In order to improve heat transfer efficiency, evaporimeter can be contained in the icehouse of high humidity, but very easily gets rusty in high humidity environment, and cold-producing medium is leaked, and refrigerator damages.In addition, after evaporimeter is made, in the storage before charging into cold-producing medium, the transportation, very easily be subjected to the influence of water in air part, the interior water in air part of evaporator tube is exceeded standard, cause inside pipe wall to get rusty, cause breakdown of refrigeration system, make the refrigerating plant cisco unity malfunction.
The utility model purpose provides a kind of wire-and-tube evaporator, and its heat transfer efficiency height can make evaporimeter be difficult for getting rusty in high wet environment, prolongs its service life; Can not be subjected to water content influence in the air in transportation, in storing, make can not enter foreign material in the evaporator tube and can not get rusty yet, the quality requirement when guaranteeing its assembling.
The utility model is realized by following technical scheme.This wire-and-tube evaporator comprises at least the evaporation section of jurisdiction of being made up of one group of repeatedly circuitous evaporation tube, each evaporate be provided with on section of jurisdiction several be distributed in evaporation tube two sides and with evaporation tube heat radiation silk welded together; At this evaporator external coated thinfilm protective coating; In evaporation tube, fill with nitrogen; Circular shape is made in the termination that is welded in the heat radiation silk on the evaporation tube.The advantage of doing like this is that evaporimeter has increased several fiber tubes, has both increased area of dissipation, has improved radiating efficiency, and because the heat radiation silk evaporation tube that each is circuitous connects together, has strengthened the deflection of evaporation section of jurisdiction.Because evaporimeter coated in appearance has thinfilm protective coating, use metal evaporation tube and heat radiation silk to be isolated by thinfilm protective coating with highly moist working environment, avoided corrosion, prolonged service life.Evaporimeter manufacture finish the back charging into cold-producing medium before, to fill in the evaporation tube with nitrogen, prevent that airborne moisture content and impurity from entering evaporation tube inside, with protect this evaporimeter inner surface store and transportation in inside pipe wall not by corrosion, avoid hidden danger, quality when guaranteeing assembling with evaporation tube two face down bondings during with the heat radiation silk, becomes circular shape with the end machining of heat radiation silk; Make be soldered on the evaporation tube after, on evaporator external, during with the electrostatic spraying thinfilm protective coating, can not take place because point discharge causes this end not spray the protective layer phenomenon.
In sum, the utility model adopts coated thinfilm protective coating on evaporator external, has avoided its outer surface corrosion-vulnerable; Employing is filled in evaporation tube with nitrogen, has prevented that airborne moisture content from entering evaporation tube inside in storage and transportation process, and inside pipe wall can not corroded, and guarantees cleaning in the pipe; To dispel the heat wire bond to evaporation tube two sides, increase area of dissipation, and strengthen the deflection of this evaporimeter; Before being soldered on the evaporation tube, end machining is become circular shape, influence the end and do not spray the protective layer phenomenon in order to avoid produce point discharge during electrostatic spraying.The utility model wire-and-tube evaporator is suitable for using on various refrigerating plants such as refrigerator, ice box, electric refrigerated display case, the low temperature wine cabinet.
Do concrete introduction with embodiment below.
Fig. 1 is the wire-and-tube evaporator structural representation,
Fig. 2,3,4 shape enlarged drawings for heat radiation silk termination,
Fig. 5 is an A place enlarged drawing among Fig. 1.
The structural representation of wire-and-tube evaporator as shown in Figure 1, present embodiment is made up of two groups of evaporation sections of jurisdiction 5, and every group of evaporation section of jurisdiction 5 is made up of repeatedly circuitous evaporation tube 1, on every group of evaporation section of jurisdiction 5, two face down bondings that are positioned at evaporation tube 1 have heat radiation silk 3, and heat radiation silk 3 has increased the area of dissipation of evaporimeter.Import and export at evaporimeter is equipped with two tube connectors 2.Coated has thinfilm protective coating on the outer surface of whole evaporimeter; this protective layer can be used on the electrostatic spray coated by the coating of epoxy resin or epoxy/polyester mixed type; to protect the top layer of this evaporimeter; this protective layer also can be made of two-layer material; promptly skin is epoxy resin or epoxy/polyester mixed type coating; internal layer is electrophoretic paint or anticorrosion enamelled coating, and the thickness of whole protecting layer can be 50 μ m to 300 μ m according to instructions for use.The antiseptic property of evaporimeter in high humidity environment greatly improved,, can reach more than 1000 hours, increased service life greatly through salt-fog resistant test.Be depicted as tube connector import and export shutoff situation map as Fig. 1,5, before evaporimeter is manufactured the warehouse-in that finishes, to fill with high pure nitrogen in the evaporation tube 1, or dew point is lower than-43 ℃ industrial nitrogen, use the import and export shutoff of rubber plug 4 then with tube connector 2, in order to avoid in storing or transporting, enter impurity, before guaranteeing being contained on the refrigerator, when this evaporimeter is charged into cold-producing medium, can reach quality requirement to this evaporation tube 1; As Fig. 2, make chamfering in the termination of heat radiation silk 3; As Fig. 3, make fillet in the termination of heat radiation silk 3, in order to avoid during the electrostatic spraying protective layer; the discharge of most advanced and sophisticated place takes place do not spray coating; for after silk 3 the tip of will dispel the heat makes slyness, with its bending and evaporation tube 1 applying, make good looking appearance also can protect inner container of icebox as Fig. 4 again.
