Abstract
The invention discloses a tube plate welding type refrigeration evaporator which comprises a heat transfer plate and an evaporating tube. The heat transfer plate is welded to the evaporating tube through a brazing filler metal layer; welding joints exist between the heat transfer plate and the evaporating tube after welding; and a plastified layer covers the surface of the heat transfer plate, the surface of the evaporating tube and the welding joints. Compared with the prior art, the tube plate welding type refrigeration evaporator has the advantages that the plastified layer covers the surface of the heat transfer plate, the surface of the evaporating tube and the welding joints; the material for the plastified layer is nontoxic polyethylene or epoxy resin; the plastified layer is good in leveling effect and can be used for filling and compensating the welding joints between the heat transfer plate and the evaporating tube; expansive force generated in periodic ice-water transformation is prevented from damaging pipelines; and the problem of leakage of a refrigerating agent is effectively solved.
Description
Technical field
The present invention relates to technical field of refrigeration equipment, in particular a kind of Tube-sheet Welding formula refrigeration evaporator.
Background technology
According to the classification of national standard " GB/T 23133 household electric refrigerator vaporizer ", conventional tube plate-type evaporator is divided into tube sheet riveting
Connect formula, tube sheet is bonded and tube sheet amplexiforms formula three kinds, the connection defective tightness between pipeline and the heat transfer plate of these vaporizers, because of
And heat transfer property is poor.
Application No. 201520503909.9, the Chinese invention patent of entitled " a kind of exposed evaporator of refrigerator " disclose one
The vaporizer that kind evaporation tube and heat transfer plate weld together, owing to current technique is limited, can not keep away between evaporation tube and heat transfer plate
The meeting exempted from produces interrupted weld seam.
The temperature of cold compartment of refrigerator is between 0 DEG C to 10 DEG C, as refrigeration and the heat transfer component of refrigerator, the temperature of refrigeration evaporator
The lowest, surface can produce condensed water, and condensed water can penetrate into the weld seam between tube sheet.The temperature of refrigeration evaporator is along with the fortune of refrigerator
OK, periodically, continually in the upper and lower fluctuation of freezing point of water, it is understood that volume can expand after water build-ups ice, evaporation
Gap between pipe, plate can be worn swollen for pipeline because of ice, the phase transformation of water durations, forms the leakage of cold-producing medium.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of Tube-sheet Welding formula refrigeration evaporator.
The present invention is achieved by the following technical solutions:
A kind of Tube-sheet Welding formula refrigeration evaporator, including heat transfer plate and evaporation tube, described heat transfer plate is by solder layer and described evaporation tube
Weld together, after welding, between described heat transfer plate and described evaporation tube, there is weld seam, described heat transfer plate surface, described evaporation tube
Surface and described commissure are coated with one layer of plasticizing layer.
Described plasticizing layer is polyethylene plasticizing layer or epoxy resin plasticizing layer.
Described plasticizing layer is to be covered at described heat transfer plate table by the one of which technique of electrophoresis process, workmanship of spraying plastics or impregnation
Face, described evaporation tube surface and described commissure.
Described evaporation tube is to be that commercial-purity aluminium prepares by 1, and described heat transfer plate is to be that alloy aluminum prepares by 3.
The present invention has the advantage that compared to existing technology
A kind of Tube-sheet Welding formula refrigeration evaporator that the present invention provides, its on heat transfer plate surface, evaporation tube surface and commissure be coated with
One layer of plasticizing layer, the material of plasticizing layer is nontoxic polyethylene or epoxy resin, and levelling is effective, can fill and make up heat transfer plate
And the weld seam between evaporation tube, it is to avoid the expansive force that ice, water periodic conversion produce damages pipeline, thus effectively prevent cold-producing medium
The problem of leakage.

Label in figure: 1 heat transfer plate, 2 evaporation tubes, 3 solder layers, 4 weld seams, 5 plasticizing layers.
Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention,
Give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
See Fig. 1 to Fig. 3, present embodiment discloses a kind of Tube-sheet Welding formula refrigeration evaporator, including heat transfer plate 1 and evaporation tube 2,
Evaporation tube 2 is to be that commercial-purity aluminium prepares by 1, and heat transfer plate 1 is to be that alloy aluminum prepares by 3.
Heat transfer plate 1 is welded together with evaporation tube 2 by solder layer 3, laminating between heat transfer plate 1 and evaporation tube 2 after welding
Face will not be completely uniform, easily forms weld seam 4 at the position of evaporation tube 2 bending, therefore the present embodiment on heat transfer plate 1 surface,
One layer of plasticizing layer 5 it is coated with at evaporation tube 2 surface and weld seam 4.Plasticizing layer 5 uses nontoxic polyethylene plasticizing layer 5 or epoxy
Resin plasticizing layer 5, levelling is effective.
Wherein, plasticizing layer 5 is to be covered at heat transfer plate 1 by the one of which technique of electrophoresis process, workmanship of spraying plastics or impregnation
At surface, evaporation tube 2 surface and weld seam 4, the levelling effect of plasticizing layer 5 is utilized to be filled and led up by weld seam 4, it is to avoid ice, water cycle
The expansive force that conversion produces damages the pipeline of evaporation tube 2, thus effectively prevent the problem that cold-producing medium leaks.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all the spirit and principles in the present invention it
Interior made any amendment, equivalent and improvement etc., should be included within the scope of the present invention.
