Abstract
The utility model relates to a vacuum phase-change heat radiator, which belongs to the field of heating apparatus. The heat radiator comprises a shell and a heat source pipe, a vacuum cavity is provided in the shell with heat radiation working medium provided therein. The heat source pipe is disposed in the heat radiation working medium below the shell, with both ends connected to the inlet and the outlet for the heat radiation working medium, wherein the heat source pipe is a spiral distorted pipe with elliptical cross section. Because that the heat source pipe is changed from a straight pipeto a spiral distorted pipe with elliptical cross section, and turbulent flow is formed in the flowing process of the heat source working medium in the spiral distorted pipe with elliptical cross section, the designed vacuum change heat radiator of the utility model, compared with the heat radiator in prior art, has advantages of largely improved dynamic performance of the heat fluid, evidently reduced heat resistance, high heat exchange efficiency, so that the heat radiator has features of high heat transmission efficiency, water and energy saving compared with phase change heat radiators ofother types.
Description
Technical field
The utility model relates to a kind of change-vacuum-phase change radiator, belongs to the heating equipment technical field.
Background technology
Chinese patent ZL95226881.7 discloses a kind of change-vacuum-phase change radiator that is used for heating, its structural principle as shown in Figure 1, heat radiation working medium 8 is set in vacuum chamber 1, in heat radiation working medium, heat source tube 2 is set, when thermal source working medium when import 3 enters heat source tube 2, heat radiation working medium is whole vacuum chamber 1 because of vaporization is full of, and makes radiator casing 4 heating, thereby reaches the purpose of heat radiation heating.The characteristics of this radiator are thermal efficiency height, economical with materials, and long service life is straight tubes but its shortcoming is a heat medium pipe 2, when thermal source working medium flows in pipe, forms typical laminar flow boundary-layer, thereby has influenced the heat exchange between thermal source working medium and the heat radiation working medium.
Summary of the invention
Content of the present utility model is a kind of change-vacuum-phase change radiator of design, changes the structure of existing phase-change heat sink, to improve the radiating efficiency of entire radiator.
The change-vacuum-phase change radiator of the utility model design, comprise housing and heat source tube, in the housing is vacuum chamber, be provided with heat radiation working medium in the vacuum chamber, heat source tube places the heat radiation working medium of lower housing portion, the two ends of heat source tube respectively with housing on thermal source working medium import with the outlet link to each other, heat source tube wherein is helically twisted elliptical cross section facial canal.
In the above-mentioned radiator, heat source tube can have three or many, and end to end back is vertical or horizontal to be arranged in the heat radiation working medium.
The change-vacuum-phase change radiator of the utility model design, compare with existing radiator, because its heat source tube changes over helically twisted elliptical cross section facial canal by straight tube, owing in helically twisted elliptical cross section facial canal endogenous pyrogen working medium flow process, form turbulent flow, increase substantially the hot fluid power performance, thermal resistance obviously reduces, and possesses very high heat exchange efficiency, therefore than the phase-change heat sink heat transfer power height of other types, have more water saving, characteristics of energy saving.

Fig. 2 is the structure principle chart of the radiator of the utility model design.
Fig. 3 is an embodiment of the present utility model.
Among Fig. 1～Fig. 3, the 1st, vacuum cavity, the 2nd, heat source tube, the 3rd, the import of thermal source working medium, the 4th, radiator casing, the 5th, thermal source sender property outlet, the 6th, ripple heat source tube, the 7th, the ripple heat source tube after folding, the 8th, heat radiation working medium.
The specific embodiment
The change-vacuum-phase change radiator of the utility model design, its structure as shown in Figure 2, comprise housing 4 and heat source tube 6, in the housing is vacuum chamber 1, be provided with heat radiation working medium 8 in the vacuum chamber, heat source tube 6 places the heat radiation working medium 8 of lower housing portion, the two ends of heat source tube 6 respectively with housing on the import 1 of thermal source working medium 5 link to each other with outlet, heat source tube 6 wherein is a bellows.
In the above-mentioned radiator, heat source tube 6 can have three or many, Figure 3 shows that an embodiment of radiator, and heat source tube 7 wherein has three, and end to end back is vertical or horizontal to be arranged in the heat radiation working medium 8.
The operation principle of this radiator is, in the bottom of housing, the hot water of heating system or other any thermal source are after heat source tube 6, with 8 heating of the heat radiation working medium in the vaccum case 1, in operating temperature range, the 8 boiling vaporizations of heat radiation working medium, steam rises to vacuum cavity 1 top, condense into liquid and heat release, by the outer surface 4 heating room airs of radiator, heat radiation working medium 8 is back to the vacuum cavity bottom, and this process constantly circulates.
