Problems solved by technology

[0002] Although there are many types and styles of existing conventional radiators, these radiators generally have problems such as large inner cavity volume, large energy consumption, easy corrosion, prone to air plugging, and uneven surface temperature.
However, in the existing heat pipe phase change radiators, due to the incompatibility of materials or the sealing of the vacuum cavity, it is easy to generate non-condensable gas in the radiator.
The non-condensable gas forms a film on the inner wall of the radiator, which hinders the condensation and heat release of the steam, resulting in a decrease in the thermal efficiency of the radiator, an increase in the startup temperature of the radiator, and even failure to start
Especially when the heat medium temperature is low or the heat medium flow is insufficient, the radiator cannot be used normally

Embodiment Construction

[0016] First, weld the upper header (1), lower header (2), heat sink (3), and finned heat medium tube (4) into one body, and the finned heat medium tube (4) is inserted into the lower header (2); then weld the vacuum pumping head (5) and the vacuum regulating valve (6) to the two ends of the upper header (1). The head (5) evacuates this cavity into a vacuum cavity (9); the heat-conducting medium (7) is filled into the vacuum cavity (9) from the evacuated head (5) by using the difference in atmospheric pressure.

[0017] During installation, according to the engineering characteristics and conditions of use, the composite heat pipe radiator fin heat medium pipe (4) for heating can be connected to the heating system in the form of connection from the bottom to the bottom, from the top to the bottom, or from the same side. Heat source (can be any kind of electricity, gas, etc.) connection. During operation, the heat source heats the heat medium (8), and the heated heat medium (8...

Abstract

A composite type heat pipe radiator for heating relates to the heating ventilating field and comprises an upper header pipe (1), a lower header pipe (2), a radiating fin (3), a fin heating medium pipe (4), a vacuum pumping head (5), a vacuum regulating valve (6), a heat-conducting medium (7) and a heating medium (8). A cavity body formed by the upper header pipe (1), the lower header pipe (2), the radiating fin (3) and the heating medium pipe (4) with the vacuum pumping head (5) and the vacuum regulating valve (6) after a vacuum device extracts the air in the upper header pipe (1), the lower header pipe (2), the radiating fin (3) and the heating medium pipe (4) from the vacuum pumping head (5); and after the air in the cavity body is extracted, a vacuum hollow cavity is formed. The heat-conducting medium absorbs heat from a heat source and transfers the heat to the heating medium (8) through the fin heating medium pipe (4); the heating medium is heated and gasified and transfers the heat to the air so as to serve the heating function. The invention has the advantages of high efficiency, safety, water and energy conservation, beauty, duration, light weight, and high borne pressure. The invention can manufactured into composite type vacuum ultra heat conducting pipe energy-saving efficient radiators of various types and specifications, such as the plate type, the pipe type, the cylindrical type, various wing types, and the like.

Description

technical field [0001] The invention relates to a radiator technology in the field of heating and ventilation, in particular to a composite heat pipe radiator for heating. Background technique [0002] Although the existing conventional radiators are of various types and styles, these radiators generally have problems such as large inner cavity volume, large energy consumption, easy corrosion, prone to air lock phenomenon, and uneven surface temperature. However, in the existing heat pipe phase-change radiators, non-condensable gas is likely to be generated in the radiators due to incompatibility of materials or sealing of the vacuum cavity. The non-condensable gas forms a film on the inner wall of the radiator, which hinders the condensation and heat release of the steam, reduces the thermal efficiency of the radiator, increases the startup temperature of the radiator, and even fails to start. Especially when the temperature of the heat medium is low or the flow of the hea...
