Embodiment Construction

[0013] Hereinafter, a heat transfer tube for an absorption refrigerator according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0014] Fig. 2 is an enlarged view showing the surface of a heat transfer tube in which fine protrusions are formed by an electroplating process according to an embodiment of the present invention.

[0015] In this embodiment, the constituent elements constituting the absorption refrigerator, for example, both the inner surface and the outer surface of the heat transfer tubes used in the evaporator (107), absorber (106), condenser (101), etc., Or copper (Cu) is electroplated only on any one of the inner surface and the outer surface, thereby forming fine protrusions as shown in FIG. 2 .

[0016] In this electroplating method, copper cyanide (CuCN) electroplating method, copper sulfate (CuSO 4 ) electroplating method, etc. In particular, copper cyanide plating is preferably employed. The compo...

Abstract

The aim of the invention is to provide a heat pipe for absorption refrigerating machine, which can improve heat transmission capability of the heat pipe by deforming a surface shape inside and outside of the heat pipe for absorption refrigerating machine. The heat pipe of the invention forms fine protrusions on surface inside and outside via electroplating process or etching process. Liquid film forming on the surface of the heat pipe can be prevented, due to a liquid film flowing phenomenon of the flowing liquid which is caused by the fine protrusion, so that, heat transmission capability of the heat pipe and performance of the absorption refrigerating machine can be improved largely.

Description

technical field [0001] The present invention relates to heat transfer tubes for absorption refrigerating machines, and more particularly, to forming fine protrusions on the inner and outer surfaces of the heat transfer tubes, capable of preventing the formation of a liquid film on the surface of the heat transfer tubes due to the surface tension of the flowing fluid Heat transfer tubes for absorption refrigerators. Background technique [0002] Absorption refrigerator is a product that uses the principle that the liquid solubility of refrigerant vapor changes through temperature and pressure. It uses water as the refrigerant and lithium bromide (LiBr) as the absorption solution for recovering the evaporated refrigerant. [0003] As shown in Figure 1, a general absorption refrigerating machine is composed of the following components: a high-temperature regenerator (103), which heats the dilute absorption liquid with an external heat source and concentrates it to obtain refrig...
