Graphite heat conductor-based electric blanket

Abstract

The invention discloses a graphite heat conductor-based electric blanket, which comprises an electric blanket; a heating cable is arranged in the electric blanket; and two pieces of graphite paper are arranged at two sides of the heating cable. A double-sided adhesive tape is arranged between the two pieces of graphite paper. The graphite heat conductor-based electric blanket is provided with thegraphite heat conductors, so that the problems of energy waste and potential safety hazard of the traditional radiating fin are solved; because the graphite has extremely strong heat conductivity (which can even exceed the heat conductivities of copper and aluminum after treatment), the graphite heat conductor can transfer the heat to a position beyond 100 millimeters in short time (within about 5 seconds) when the heating cable generates heat, the interval of the internal heating cable can reach over 150 millimeters and the heating effect is not affected; and in addition, because the heat can be quickly dissipated by the graphite heat conductors, namely the graphite paper, heat is not accumulated nearby the heating cable, and risks are avoided.

Description

technical field [0001] The invention relates to an electric heating blanket, in particular to an electric heating blanket based on a graphite heat conductor. Background technique [0002] The traditional electric blanket is a kind of contact electric heating appliance. It weaves or sews a special soft cable heating cable (resistance wire) with a standard insulation performance into the blanket in the shape of a snake, and emits heat when it is energized. . However, the traditional electric blanket also has the following problems: First, the heat accumulation phenomenon of the traditional electric blanket greatly wastes electric energy, mainly in that in order to achieve uniform heating, the heating cables need to be arranged very densely; Blankets also have huge safety hazards, because when the heat accumulation reaches a certain level, it may cause the temperature near the heating element to be too high, thus causing a fire. This example happens from time to time during th...

However, the traditional electric blanket also has the following problems: First, the heat accumulation phenomenon of the traditional electric blanket greatly wastes electric energy, mainly in that in order to achieve uniform heating, the heating cables need to be arranged very densely; The blanket also has a huge safety hazard, because when the heat accumulation reaches a certain level, it may cause the temperature near the electric heating element to be too high, thus causing a fire. This kind of example often occurs during the use of electric blankets
