Ice-water-gas phase change cooling clothes based on fiber cold conduction and evaporation heat absorption

Abstract

The invention relates to the technical field of cooling clothes, and discloses an ice-water-gas phase change cooling clothes based on fiber cold conduction and evaporation heat absorption, which comprises a cooling clothes body, an ice-water phase change low-temperature source is embedded in the cooling clothes body, and the main body of the ice-water phase change low-temperature source is an ice bag. The cooling clothes body is formed by compounding a water absorption evaporation heat absorption layer, a metal fiber cold conduction heat absorption layer and a flexible skin-friendly breathable sweat absorption layer; the ice-water-gas phase change cooling garment based on fiber cold conduction and evaporation heat absorption does not need any power source, truly realizes zero-energy-consumption heat absorption and cooling, is low-carbon and environment-friendly, and is suitable for workplaces with strict requirements on explosion prevention, electromechanical equipment power and the like; and under the condition of no power system, the weight of the whole set of cooling clothes is greatly reduced, and the cooling clothes are more comfortable and convenient to wear and do not interfere with daily work. The cooling clothes are novel in design, simple in structure and low in cost, and have the advantages of convenience, easiness in wearing and good cooling effect.

Description

technical field [0001] The invention relates to the technical field of cooling clothing, in particular to an ice-water-gas phase change cooling clothing based on fiber cold conduction and evaporation heat absorption. Background technique [0002] High-temperature environment operations are found in almost all walks of life in national production, such as firefighters entering and exiting fire sites, deep well coal mining workers, furnace and boiler workers, etc., construction workers, porters, traffic policemen, cleaners, etc. who work outdoors at high temperatures in summer. High temperature work can cause varying degrees of damage to the human circulatory system, digestive system, urinary system, nervous system, etc., resulting in rapid heartbeat, increased blood pressure, increased cardiovascular burden, loss of appetite, indigestion, concentrated urine, and excessive burden on the kidneys , the brain reaction speed and attention are reduced, which eventually leads to a d...

Problems solved by technology

[0004] 1) Use engineering means to carry out regional cooling measures for the local working environment. This method usually has a large amount of engineering and high cost, and is only suitable for relatively closed small spaces. venue not applicable

[0005] 2) Use individual cooling suits for individual absorption / dissipation. The research and development of fabrics for heat dissipation and cooling are mostly carried out around improving the heat dissipation capacity of fibers for human body heat generation, that is, enhancing or accelerating the ability of heat to diffuse from the body surface to the external environment. For high temperature Radiation or convective heat transfer from high-temperature air to the body surface is difficult to play a role in the working scene, that is, such fabrics can only speed up the heat exchange between the air layer on the body surface and the outside world. Ideally, it can be consistent with the outside temperature, but it is difficult to lower it. outside temperature, so it is not suitable for individual cooling in high-temperature operation scenarios

[0006] For heat absorption and cooling, traditional protective clothing is currently equipped with an air-conditioning system, a cold water circulation system, or a partial installation of ice bags and cold water bags inside the protective clothing. The former needs to be equipped with a power system, an air / water circulation system, and a power supply system. These three institutions not only have complex structure and heavy weight, but will greatly increase the physical load of operators, seriously affect normal operations, reduce operating efficiency and working hours, and it is difficult to obtain explosion-proof, coal safety and other special operating places. Access certification

Partially adding ice packs and cold water bags to the protective clothing can usually only last for less than 2 hours, which is not enough to support the use of 8-hour full-time shifts, and it is easy to cause local overcooling, which is not comfortable enough. Moreover, high-temperature work will increase the amount of sweating on the human body , correspondingly, the required drinking water is greatly increased
