Abstract
The utility model relates to a heat radiation device, in particular to a radiator of a power transformer, and overcomes the shortcomings of the conventional coating technology in the aspects of environmental protection and heat radiation efficiency. A cathode electrophoretic paint layer and a water-based surface painting layer are coated on the surface of a radiator main body, the film thickness of the cathode electrophoretic paint layers on the surface and in the inner chamber of the radiator is 25-40 micrometers, and the film thickness of the water-based surface painting layer is 30-40 micrometers. In the utility model, both the inner chamber and the outer chamber of the radiator are coated at one time during electrophoresis to achieve high manufacturing efficiency, so that environmental protection is realized and the resource is saved while the anti-corrosion function is served.
Description
Technical field
The utility model relates to heat abstractor, specifically a kind of power transformer radiator.
Background technology
At present, the radiator coating structure that power transformer adopts is made of epoxy zinc rich primer (or hot galvanizing), intermediate coat and finish paint, and heavy metal such as coating zinc, benzene and dimethylbenzene and harmful substance are used in a large number in coating process.For reaching anticorrosion requirement thickness substantially all more than 140um, the blocked up heat radiation function that also reduces radiator of thickness.
The utility model content
In order to overcome the existing deficiency of radiator coating on environmental protection, heat radiation function, the purpose of this utility model is to provide a kind of power transformer radiator.
The purpose of this utility model is achieved through the following technical solutions:
The utility model radiator body appearance scribbles ability cathode electrophoresis enamelled coating and aqueous finish paint layer successively, and lumen of radiator scribbles the ability cathode electrophoresis enamelled coating.
Wherein: the cathode electrodip painting tunic of this radiator appearance and inner chamber is thick to be 25～40um, and the aqueous finish paint tunic is thick to be 30～40um.
The beneficial effects of the utility model are:
1. the utility model has not only been eliminated in coating procedure and has been contained benzene and dimethylbenzene etc. human body is had the coating of harm, and greatly reduces coating film thickness when satisfying corrosion resistance, has overcome the deficiency of existing coating technology aspect environmental protection, heat radiation function.
2. coating processing in the exocoel in can once realizing in electrophoresis process realizes making efficient and improves.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 2, radiator body appearance of the present utility model scribbles ability cathode electrophoresis enamelled coating and aqueous finish paint layer successively, and lumen of radiator scribbles the ability cathode electrophoresis enamelled coating.Wherein outer coating film 5 of cathode electrodip painting and cathode electrodip painting inner chamber are filmed and 7 are infiltrated heat radiating fin structure body 6 by electrophoresis process, and aqueous finish paint is filmed and 4 is attached on the outer coating film 5 of cathode electrodip painting again.The cathode electrodip painting tunic of appearance and inner chamber is thick to be 25～40um, and aqueous finish paint enamelled coating thickness is 30～40um.
The cathode electrodip painting that the utility model adopted is commercial product, purchase in the environmental-friendly lead-free cathode electrodip painting of U.S. PPG company, being generically and collectively referred to as the cation cathode electrodip painting, is that 1: 6: 8 ratio is allocated in cell body and formed by cathode electrodip painting epoxy resin CR961B, cathode electrodip painting graining paste CP523 and deionized water according to mass ratio; The aqueous finish paint that is adopted is commercial product, purchases in the air-dry water-based finish paint HV43 of one-component of German CHING company.
The structure of power transformer radiator as shown in Figure 1, oil collecting pipe A1 links to each other with fin 2, fin 2 links to each other with oil collecting pipe B3.Oil collecting pipe A1, oil collecting pipe B3 link to each other with the inner chamber of fin 2.
The utility model coating process process flow diagram as shown in Figure 3, with radiator of the present utility model through oil removing derust, the preceding road of phosphatization handles, and cleans, immerse then in the cathode electrodip painting (environment-friendly water-based lacquer).This radiator is linked to each other with the D.C. regulated power supply negative electrode, the D.C. regulated power supply anode is linked to each other with cathode electrodip painting.As shown in Figure 4, D.C. regulated power supply 8 makes cation electrophoretic paint molecule 10 form electrophoresis process to heat spreader structures body 3 high speed impact by the electromotive force effect.As shown in Figure 5, cation electrophoretic paint molecule 10 to the lumen of radiator electricity.In galvanization, the electrophoretic paint molecule is by courses of reaction such as electrophoresis, electro-deposition, electric osmose, electrolysis, make coating by deposition, infiltration more firm be attached to exocoel surface in the radiator, by adjust voltage and conduction time accurate controlling diaphragm layer thickness.Wherein voltage is 200V～240V, and be 3min～5min conduction time.Again through changing finish paint (environment-friendly water-based lacquer) showering operation over to behind the preface cleaning, drying down.As shown in Figure 6, aqueous finish paint 13 carries out showering by 12 pairs of heat spreader structures bodies of leaching paint rifle, finishes the coating of this external surface of heat spreader structures finish paint.Through promptly finishing the preservative treatment process after the oven dry again.
