Hollow heat pipe radiator

Abstract

The invention discloses a hollow heat pipe radiator. The hollow heat pipe radiator is composed of hollow heat pipes, a heat conducting pipe and electric heating devices. Each hollow heat pipe is composed of an inner pipe, an outer pipe, a valve and a heat conducting working medium. The length of each outer pipe is the same as the length of the corresponding inner pipe. The upper ends and the lower ends of each outer pipe and the corresponding inner pipe are fixedly welded together through metal plates. The diameter of each outer pipe is 2-30 mm greater than that of the corresponding inner pipe. Each outer pipe is provided with radiating fins. A gap space cavity of each outer pipe and the corresponding inner pipe is filled with the heat conducting working medium. Valves are arranged in the position of gaps of the bottoms of the lower ends of the pipes. The valves are used for filling the heating conducting working medium, exhausting and vacuumizing. The electric heating devices are installed in the interiors of the gaps of the bottoms of the lower ends of the outer pipes and the inner pipes. The hollow heat pipe radiator is high in exchanging efficiency; the radiating area is increased by 1.2-1.8 times under the condition that the space and the volume are the same; the heat energy conduction is facilitated; the radiating speed of the heat energy is increased; the heat energy is well exchanged; the hollow heat pipe radiator is capable of saving energy and environmentally friendly.

Description

technical field [0001] The invention relates to a heat pipe radiator, in particular to a hollow heat pipe radiator. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by G.M.Grover of Los Alamos National Laboratory in the United States in 1963. Heat is transferred rapidly away from the heat source, and its thermal conductivity exceeds that of any known metal. [0003] At present, the heat pipes on the market are all solid, and there is no development and use of hollow heat pipes; most of the heat conduction and heat dissipation equipment on the market now use single heating and finned radiators for heat dissipation and heating, but their radiators are large in size and small in heat dissipation area , Low heat conduction efficiency. Contents of the invention [0004] The problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a hollow heat pipe radiator. The working ...
