Abstract

The invention discloses an energy storage heating type electric heating rope based on a phase change material. The energy storage heating type electric heating rope relates to an energy storage and heat preservation equipment of a phase change material, which can be spliced and extended into various shapes, and is specific to the human body. Warm the area. The energy storage heating type electric heating rope includes a braid, a waterproof insulating rubber layer, a resistance wire, a conductive joint, a phase change material, a thermal insulation medium, a waterproof film layer, and a conductive joint card interface. When the resistance wire is energized and heated, the phase change material absorbs and stores a large amount of latent heat, and at the same time, the heat is transferred to the thermal insulation medium to heat the braid; after the power is turned on, the temperature of the thermal insulation medium begins to drop. The phase-change material solidifies and releases heat, and the heat is transferred to the heat-insulating heat medium to keep the braid continuously warm. The invention utilizes the special physical properties of the phase change material to provide heat for the braided fabric, so that the body parts can keep warm and keep cold.

technical field

The invention relates to an energy storage and heat preservation device based on a phase change material, in particular to a spliced civil heat preservation electric heating device.

Background technique

In cold weather, people are used to wearing knitted fabrics such as scarves to keep the neck warm. For other parts of the body such as the abdomen, legs, etc., most people will add some clothing to keep warm. However, this common heating method can no longer meet the needs of consumers, and there are certain deficiencies in continuous warmth preservation, and the heat preservation time is not long enough. Moreover, for those consumers who suffer from symptoms such as cervical spondylosis, joint pain, and rheumatism, because the thermal insulation performance needs to be improved, and they cannot keep warm for specific parts of the human body, they do not play a good role in keeping warm and dispelling cold and relieving pain.

For now, there are some product patents based on phase-change materials, such as CN204016600U, which proposes a phase-change energy storage heat storage electric heating bag, and CN202002202U, an electric heater using phase-change materials. However, these heating devices have a narrow scope of application, inflexible use, and limited contact area with the human body, so the heating devices cannot be properly adjusted and changed according to the needs of consumers. Therefore, the present invention proposes an energy storage heating heating cord based on phase change materials, which can be spliced and extended into various shapes according to the needs of consumers, so as to achieve the effect of continuously keeping warm and warding off cold.
