Claims

1. A thermal insulation material capable of absorbing solar energy and releasing heat, comprising a three-layer structure, wherein: a first layer comprises gas-filled bladders filled with a safe and stable substance having a relatively high specific heat capacity, the substance being selected from hydrogen, helium, or other materials, such substances possessing the characteristic of strong heat absorption capacity and slow heat release; a second layer comprises a soft and comfortable material having the effect of protecting the absorbed thermal energy from exchange when serving as a thermal insulation material; and a third layer comprises a thermal insulation layer having the effect of protecting the absorbed thermal energy and preventing heat exchange between an external temperature and an internal temperature, thereby avoiding unnecessary heat exchange, reducing thermal energy loss, and protecting a human body from excessive absorbed heat that may be intolerable.

2. A method of utilizing a multi-purpose energy-saving thermal insulation material capable of absorbing solar energy and releasing heat, comprising: during daytime when sunlight is present, positioning an absorption layer comprising gas-filled bladders so as to fully absorb solar energy and store thermal energy within the absorption layer under protection of a thermal insulation layer; and when temperatures decrease at night and heat release is required, reversing the material so that the thermal insulation layer is positioned externally, thereby enabling slow release of heat from the bladders, protecting the absorbed thermal energy from exchanging heat with the external environment, reducing energy loss, and enabling full utilization of the absorbed energy.

3. A garment or blanket fabricated from the thermal insulation material of claim 1, wherein: the outermost layer is a heat absorption layer comprising gas-filled bladders capable of fully absorbing and storing thermal energy, the middle layer is a soft and comfortable isolation layer, and the innermost layer is a thermal insulation layer having the effect of protecting the stored thermal energy, ventilation perforations are provided in interstices between the bladders of the heat absorption layer, the number and size of the perforations varying according to intended use to enable breathability and comfort, the gas within the bladders provides a protective cushioning function for the human body in the event of accidental falls, when fabricated as clothing, the garment is worn during daytime with the bladder side facing outward to absorb heat and at night reversed with the bladder side facing inward to release heat to the human body, and when fabricated as a blanket, the bladder side is faced outward and exposed to sunlight during the day to store thermal energy, and at night the bladder side is faced inward toward the body to release heat and supply warmth.

4. The thermal insulation material of claim 1, wherein the safe and stable substance filling the gas-filled bladders is helium.

5. The thermal insulation material of claim 1, wherein the safe and stable substance filling the gas-filled bladders is hydrogen.

6. The thermal insulation material of claim 1, wherein the safe and stable substance filling the gas-filled bladders is an inert gas.

9. The thermal insulation material of claim 1, wherein the gas-filled bladders are formed as interconnected cells configured to evenly distribute absorbed thermal energy.

10. The method of claim 2, further comprising regulating the rate of heat release by varying a thickness of the thermal insulation layer.

11. The method of claim 2, wherein the material is oriented with the bladder side facing a solar radiation source for at least two hours to maximize stored energy.

12. The garment of claim 3, wherein the ventilation perforations are circular and have a diameter between 0.5 millimeters and 5 millimeters.

13. The garment of claim 3, wherein the ventilation perforations are arranged in a grid pattern to optimize breathability.

14. The garment of claim 3, wherein the garment further comprises a fastening mechanism selected from zippers, buttons, or hook-and-loop fasteners to facilitate reversible wearing.

15. The blanket of claim 3, wherein the blanket further comprises an outer protective fabric layer resistant to ultraviolet degradation.

DETAILED DESCRIPTION OF EMBODIMENTS

[0026] When used as a clothing material, one side of the garment is entirely composed of this material. During the daytime, the bladders face outwards to absorb heat. When heat release is required at night, the garment is reversed and worn with the bladder side facing inwards against the body, whereupon the bladders automatically release heat to supply warmth to the human body.

[0027] The material comprises three layers: the first layer is the {circle around (4)} Bladder Layer, the second layer is the {circle around (2)} Isolation Layer, and the third layer is the {circle around (3)} Thermal Insulation Layer.

[0028] Each bladder is filled with a safe and stable gaseous filler having a relatively high specific heat capacity, and numerous {circle around (5)} Ventilation Perforations exist between each bladder.

[0029] During the daytime, the {circle around (4)} Bladder Layer faces outwards to absorb heat, the {circle around (2)} Isolation Layer protects the human body, and the {circle around (3)} Thermal Insulation Layer prevents heat exchange loss from the bladders.

[0030] At night, the {circle around (4)} Bladder Layer faces inwards, slowly releasing heat towards the human body.

[0031] The following embodiments will further describe the thermal insulation material capable of absorbing solar energy and releasing heat according to the present invention in detail with reference to the drawings. It is apparent that the described embodiments are only part of the embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
