Problems solved by technology

These two problems are: first, how to effectively emit heat in the form of infrared radiation; second, the actual radiative cooling system is also absorbing heat radiation and sunlight while radiating heat energy to the outside world.
Although some people have tried to install this infrared radiation cooling system on the roof of the building, hoping to reduce the temperature and save energy, there are no public documents and reports on the application of the infrared radiation cooling principle to umbrellas.

Embodiment 1

[0019] A sunny umbrella with infrared radiation cooling function, its structure is, from the outermost surface of the umbrella to the bottom, there are a high-density polyethylene (HDPE) layer, an infrared conversion and infrared radiation layer, a silver-coated sunlight reflection layer, and an umbrella base. adhesive layer. The infrared conversion and infrared radiation layer is composed of a continuous polymer material polyvinyl fluoride (PVF) with infrared conversion and infrared radiation functions accounting for 93% of the total mass of the layer and an average particle size embedded on it accounting for 7% of the total mass of the layer Composed of 8 micron infrared conversion and infrared radiation zirconia microbeads.

[0020] The sun umbrella of this embodiment can reflect more than 97% of the sunlight. At the same time, the heat can be converted into infrared radiation and radiated to space through the 8 to 13 micron infrared radiation window of the atmosphere. At...

Embodiment 2

[0022] An infrared radiation cooling beach umbrella, its structure is, from the outermost surface of the umbrella to the bottom, there are respectively a high-density polyethylene (HDPE) layer of high light-transmitting polymer polymer material, an infrared conversion and infrared radiation layer, and a vacuum aluminum film sunlight reflection layer. , and the bonding layer of the umbrella base. The infrared conversion and infrared radiation layer is composed of a continuous polymer material polyvinyl chloride (PVC) with infrared conversion and infrared radiation functions accounting for 91.5% of the total mass of the layer and an average particle size of 8.5% of the total mass of the layer embedded on it. It is composed of 8.6 micron infrared conversion and infrared radiation glass beads.

[0023]If the beach umbrella in this embodiment installs a solar panel on the outer surface of the infrared radiation cooling umbrella, use the solar panel to charge the charging treasure t...

Embodiment 3

[0026] The utility model relates to a parabolic focused infrared radiation refrigerating umbrella with a long handle and pointed head. The structure is basically the same as other infrared radiation cooling umbrellas. From top to bottom, there are high-density polyethylene (HDPE) layer, infrared conversion and infrared radiation layer, high-efficiency sunlight reflection layer, and the bonding layer with the umbrella base. The bottom layer is Transparent canopy.

[0027] Among them, the infrared conversion and infrared radiation layer is composed of continuous polymer material polyvinyl fluoride (PVF) which has infrared conversion and infrared radiation functions and accounts for 90% of the total mass of the layer, and an average particle size of 10% of the total mass of the layer is inlaid on it. Composed of infrared conversion and infrared radiation boron glass beads with a diameter of 7 microns. The base material of the refrigerated umbrella is polyurethane (TPU), and the ...

Abstract

The invention relates to an infrared radiation refrigeration umbrella. The umbrella can serve as a sun-rain dual-purpose umbrella, a sunshade, a beach umbrella and a rain-proof umbrella. A material which is close to total reflection to sunlight and an infrared conversion radiation refrigeration material cover an umbrella base in a layered mode, and a cooling refrigeration system is formed. The system is composed of four layers of functional materials which comprise a high-density polyethylene layer, an infrared conversion and infrared radiation layer, an efficient sunlight reflection layer anda bonding layer of the umbrella base from outside to inside respectively. The infrared conversion and infrared radiation layer converts heat into infrared radiation, and particularly converts heat into infrared rays of 8-13 microns or infrared rays with wavelength of 18-32 microns which can pass through an atmosphere infrared radiation window and radiates to the outer space; the umbrella is insulated with upper-layer air through high-density polyethylene, the high-density polyethylene protects a lower-layer material, and direct heat exchange of surrounding air and the umbrella is reduced.

Description

technical field [0001] The invention relates to an infrared radiation cooling umbrella, which belongs to the technical field of daily necessities. Background technique [0002] In the hot summer, umbrellas can play the role of sunshade, especially the main function of dual-purpose umbrellas for eyes and rain, parasols, beach umbrellas, etc. is sunshade. Under direct sunlight, the umbrella surface will heat up due to absorbing sunlight, causing the temperature on the outer surface of the umbrella to often exceed the ambient temperature by a large margin. The high temperature and heat of the umbrella surface will be transmitted to the sheltered person under the umbrella through thermal radiation, causing people to feel stuffy, sweating, uncomfortable and even heat stroke. Although the absorption of the sun by the umbrella has been slowed down by increasing the sun reflectivity, the umbrella still continuously obtains heat from the sun, resulting in heat accumulation and tempe...
