Problems solved by technology

This kind of cooling vest can be carried freely, suitable for wearing next to the body, the cooling energy is evenly distributed, and can be recycled by adding a cold source. In the environment, the cold source will be consumed quickly, and the cooling effect lasts relatively short, especially in the wild, the cold source cannot be stored for a long time and recovered in a short time

Abstract

The invention relates to the technical field of protection products and provides a cooling vest. The cooling vest is characterized by comprising a vest body, a storage tank and a flow guide pipe, and cooling pipes are distributed on the inner side of the vest body and connected with the storage tank through the flow guide pipe; the storage tank is provided with a storage tank switch and stores liquid carbon dioxide. The cooling vest is light, good in cooling effect and capable of conducting cooling for sunstroke prevention of an individual and is provided for high-temperature working personnel and field working personnel; when a person feels hot, the storage tank switch is switched on, pressure is reduced, part of liquid carbon dioxide is gasified and then enters the cooling pipes of the vest body for heat exchange with the body, and thus the effect of reducing the temperature of the human body is achieved. Liquid carbon dioxide is a refrigerant and can absorb a large amount of heat when evaporated, and the heat of evaporation of liquid carbon dioxide is 578 kJ / kg. Carbon dioxide is nontoxic and does not pollute the environment when discharged out, and meanwhile the price of liquid carbon dioxide is low.

Description

technical field [0001] The invention relates to the technical field of protective products, in particular to a cooling vest. Background technique [0002] In many high-temperature or field working environments where air-conditioning equipment cannot be installed, severe heat stress will cause abnormal changes in human physiological functions, especially body temperature regulation, water-salt metabolism, blood circulation and other functions, which will reduce work efficiency and affect judgment. In severe cases, it may cause heat stroke and even endanger life safety. In order to solve the above problems, cooling vests arise at the historic moment. [0003] Existing cooling vests that use water circulation to cool down use cooling pipes wrapped in the cooling vest, or a film wrapped around the waist, and pipelines are installed in the film to achieve water circulation cooling. This cooling vest has poor air permeability and cooling performance. The area distribution is unb...
