Abstract
A heat exchanger comprises a refrigerant pipe for carrying a refrigerant, and a heat exchange pin having the refrigerant pipe provided through and performing heat exchange with air. Since the heat exchange pin contains a metal plate for performing heat transfer, and an anticorrosive layer for preventing corrosion of the metal plate is formed of an anticorrosive agent of resin material which has least influence on human body, the heat exchanger can be further safely manufactured and used. Thereby, the invention provides an anticorrosive agent which is usable further safely, and a heat exchanger provided therewith.
Description
Technical field
The present invention relates to a kind of heat exchanger, say in more detail, relate to less and anticorrodent that can safer use and the heat exchanger that possesses it influence of human body.
Background technology
In general, heat exchanger is to be applicable to refrigeration system and to make cold-producing medium and equipment that air carries out heat exchange, possess: inside the refrigerant pipe of flow of refrigerant is arranged and run through refrigerant pipe is set and increase and air between a plurality of heat exchange inserted sheets (pin) of heat exchange area, carry out high efficiency heat exchange at the cold-producing medium of cold-producing medium internal flow by heat exchange inserted sheet and air.
At this moment, the heat exchange inserted sheet constitute by metallic plate so that and the heat transmission between the air carry out easily, but when the heat exchanger that will use this heat exchange inserted sheet uses as evaporimeter, produce condensed water at the airborne moisture of the surface condensation of heat exchange inserted sheet.Therefore, on the heat exchange inserted sheet, be disposed with the hydrophilic layer that being used on metal sheet surface prevents the anticorrosion layer of corrosion of metal sheet and impel the easy discharge of condensed water.
Yet in such heat exchanger in the past, anticorrosion layer is usually by containing Cr VI (Cr
6) anticorrodent form, but Cr VI is a kind of of heavy metal and human body demonstrated harmful toxicity, therefore is subjected to legal constraints recently and makes using and be restricted.
Summary of the invention
The present invention puts and the invention finished in view of the above-mentioned problems, and its purpose is to provide a kind of influence to human body still less and the anticorrodent that can use safely and the heat exchanger that possesses it.
In order to achieve the above object, according to a technical scheme of the present invention, a kind of heat exchanger is provided, it is characterized in that: possess the refrigerant pipe that flow of refrigerant is arranged and run through described refrigerant pipe is set and and the heat exchange inserted sheet that carries out heat exchange between the air, described heat exchange inserted sheet comprises the metallic plate that carries out heat and transmit, forms and cover described metallic plate with the anticorrosion layer of the corrosion that is used to prevent described metallic plate and cover the outside of described anticorrosion layer and the hydrophilic layer that is formed by the high material of hydrophily by resin material.
In addition, described anticorrosion layer is preferably formed by the anticorrodent that comprises epoxy resin and phenolic resins.
In addition, described anticorrodent preferably further comprises acrylic resin, and the effect of this acrylic resin is that a side combines with epoxy resin, and the opposing party combines with phenolic resins, thereby keeps the state of epoxy resin and the indirect combination of phenolic resins.
In addition, described epoxy resin preferably comprises bisphenol A type epoxy resin.
In addition, described hydrophilic layer is preferably formed by the hydrophilizing agent that comprises cabosil.
According to another technical scheme of the present invention, a kind of anticorrodent is provided, it is characterized in that, comprise: epoxy resin and phenolic resins and acrylic resin, wherein, one side of acrylic resin combines with epoxy resin, the opposing party combines with phenolic resins, thereby keeps the state of epoxy resin and the indirect combination of phenolic resins.
According to the present invention,, therefore can more safely make and use heat exchanger owing on the heat exchange inserted sheet, use anticorrodent to form anticorrosion layer to the few resin material of human influence.
Description of drawings
Fig. 1 is the stereogram of expression heat exchanger of the present invention.
Fig. 2 is the summary section of formation of the heat exchange inserted sheet of expression heat exchanger of the present invention.
The specific embodiment
Below, describe preferred implementation of the present invention with reference to the accompanying drawings in detail.
As shown in Figure 1, the heat exchanger 100 of using anticorrodent of the present invention possesses: there is the refrigerant pipe 10 of flow of refrigerant inside and is formed and by running through the heat exchange inserted sheet 20 that refrigerant pipe 10 increases the heat exchange area of air and refrigerant pipe 10 is set by the high thin plate of thermal conductivity.
As shown in Figure 2, heat exchange inserted sheet 20 is to be made of so that carry out heat transmission easily metallic plate, and in the present embodiment, metallic plate 21 is formed by thermal conductivity and the good aluminum of corrosion resistance.
When using as evaporimeter, form the condensed water that forms by airborne hydrogenesis on the surface of heat exchange inserted sheet 20, so metallic plate 21 can be exposed in the environment of easy corrosion when such heat exchanger 100 is applied to freeze cycle.
Thereby, on heat exchange inserted sheet 20, be formed with anticorrosion layer 22 to prevent the corrosion of metallic plate 21, but anticorrosion layer of the present invention 22 is removed virose Cr VI (Cr6) compositions, will be to the influence of human body the anticorrodent of few resin material be coated on the metallic plate 21 and form.As anticorrodent, be to form, and in the present embodiment, use bisphenol A type epoxy resin as epoxy resin by corrosion resistance good epoxy resin and phenolic resin mixing.
But, comprise epoxy resin and phenolic resins and the anticorrosion layer 22 that forms has extremely good corrosion resistance, but a little less than the mutual adhesion of epoxy resin and phenolic resins, have the combined structure of easy destruction.
Given this, anticorrosion layer 22 in the heat exchanger 100 of the present invention also further comprises acrylic resin, the effect of this acrylic resin is that a side combines with epoxy resin, and the opposing party combines with phenolic resins, thereby keeps epoxy resin and the indirect state that mutually combines of phenolic resins.
Following formula 1 is the reaction equation of epoxy resin and phenolic resins.
[changing 1]
Following formula 2 is reaction equations of phenolic resins and acrylic resin.
[changing 2]
(in the formula, R " expression alkyl)
Can recognize that from formula 1 and formula 2 acrylic resin is with epoxy resin and phenolic resins combination respectively, so that the indirect combination of epoxy resin and phenolic resins, therefore can keep the stable bonding state of epoxy resin and phenolic resins.
In addition, in order to discharge easily the condensed water that produces on the surface of heat exchange inserted sheet 20, coating hydrophilizing agent on heat exchanger 100 of the present invention and form hydrophilic layer 23.Hydrophilizing agent is by forming with the high material of the hydrophily of water, form moisture film easily on the surface of heat exchange inserted sheet 20 easily, and after forming moisture film, condensed water moving along moisture film, so can discharge condensed water easily.
In the present embodiment, hydrophilizing agent contains the good cabosil of hydrophily, and except cabosil, also contain the Nano Silver (nanosilver) that possesses antibacterial ability and the isothiazoline that possesses fungus resistance is mould inhibitor, can also suppress bacterium or mould breeding on heat exchange inserted sheet 20.
