Instant heating and heat accumulation dual purpose heating pad

Abstract

The invention provides an instant heating and heat accumulation dual purpose heating pad. The heating pad is characterized by comprising an elastic material layer (2), a heat accumulation layer (4) and a heat insulation layer (6), wherein the heat accumulation layer (4) is arranged between the elastic material layer (2) and the heat insulation layer (6) and mainly composed of phase change materials; and further comprising a first heating layer (3) and a second heating layer (5), wherein the first heating layer (3) is arranged between the elastic material layer (2) and the heat accumulation layer (4), and the second heating layer (5) is arranged between the heat accumulation layer (4) and the heat insulation layer (6). According to the heating pad, an air layer with good heat insulation effects and the characteristic of transmitting heat effectively after air is discharged by gravitational compression can be formed through the elastic material layer, so that the heating pad can achieve effects of instant heating and long-time heat insulation simultaneously, and further energy is effectively saved.

Description

technical field [0001] The present invention relates to a thermal pad, in particular to a dual-purpose thermal pad for instant heat and thermal storage. Background technique [0002] Energy is the driving force of social development, and energy shortage will seriously hinder economic development and social progress. In the face of the increasingly serious energy crisis, energy storage technology, as an advanced form of energy use, has received widespread attention. Only reasonable development and utilization of energy, and active improvement of energy utilization efficiency are the feasible ways to face the crisis. Therefore, in a modern society where energy is in short supply, energy conservation has become a topic that everyone has been thinking about. [0003] Energy storage technology can effectively improve energy utilization efficiency. Taking phase change energy storage and heat storage as an example, it stores energy in the form of heat for use when needed, thereb...

Problems solved by technology

However, one of the biggest disadvantages of electric blankets is that they need continuous power supply, which is very inconvenient for workers who often work outdoors and users who need to carry miniaturized heating pads.

[0005] The thermal pad can continuously release heat after charging and storing energy without being connected to the power supply all the time, but the thermal pad in the prior art has the defect that the heat preservation time is not long enough. During use, a large amount of heat is transferred to the air instead of the human body
