Abstract

The invention relates to a vertical type powder heat storage type heat pipe electric pad which comprises an external shell, an internal shell, a heat pipe and an axial-flow fan. The heat pipe is composed of a vertical pipe and a lower cavity communicated mutually. The vertical pipe is positioned in the internal shell, the lower cavity is connected with the lower part of the internal shell and electric heating components are arranged therein; the internal shell and the heat pipe are positioned in the external shell, heat storage powder is filled in the internal shell, annular gaps forming air passages are arranged between the external side wall of the internal shell and the internal side wall of the external shell; the axial-flow fan is positioned in the external shell above the internal shell, a plurality of air inlets distributed circlewise are arranged on the side wall of the external shell, which is positioned at the bottom of the air passages; and an air outlet is arranged at the top part of the external shell. The pad of the invention is simple in structure and convenient in use and is applicable to being used for the off-peak period of an electricity grid so as to save electric resources and reduce heating cost.

Description

technical field [0001] The invention relates to a vertical powder heat storage type heat pipe electric heater, which can be mainly used for residential heating. Background technique [0002] At present, there are many types of electric heaters, including electric oil heaters, far-infrared electric heaters, halogen tube electric heaters, convection electric heaters, enamel steel electric heaters, etc. Among them, the heat pipe type is due to its fast heat conduction. The effect is good, and it has become a relatively fast-growing technology. For example, China's 200610023443.8 invention patent application provides a heat pipe electric heater, including a heat pipe, a heating element, a heating body, an anti-dry copper wire mesh and a bottom casing. . The bottom casing and the heat dissipation pipe are integrated to form a closed space, which is filled with working fluid. The outer casing of the heating element is covered on the cylindrical heating element, and the anti-dry ...
