Thermoconditional suit achieving cooling and heating

Abstract

The invention discloses a thermoconditional suit achieving cooling and heating, and belongs to the technical field of labor protection clothing. The thermoconditional suit achieving cooling and heating comprises an air compressor, a double-circuit vortex tube and a thermoconditional suit body. An air inlet nozzle is formed in one side wall of the double-circuit vortex tube, a vortex chamber is arranged on the edge in the tangential direction of the air inlet nozzle, a cold end tube is arranged on one side of the vortex chamber, and a hot end tube is arranged on the other side of the vortex chamber. A separating pore plate is located between the cold end tube and the vortex chamber, a hot end regulating valve is arranged at one end of the hot end tube, and an additional loop is arranged in the center of the hot end regulating valve. The air compressor is directly connected with a gas-liquid separator, the gas-liquid separator is connected with a dryer, the dryer is connected the hot end regulating valve through a hose and then connected with the double-circuit vortex tube, and the hot end tube of the double-circuit vortex tube is connected with an exhaust guide pipe in the thermoconditional suit body. The thermoconditional suit is ingenious in design, safe to use, easy to operate, quite convenient to carry, easy to clean, low in cost and capable of meeting use needs, and a good work effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of labor protection clothing manufacturing, and in particular relates to a dual-purpose temperature-regulating clothing for cold and heat. Background technique [0002] Among the many occupations, the staff of many positions often have to face the working environment of high temperature or severe cold. When engaged in physical labor outdoors in summer or in other high-temperature environments, the physical energy consumption of the human body is very large, and it is particularly prone to fatigue and low work efficiency; when it is outdoors in winter or in other severe cold conditions, body heat is quickly lost during labor , which leads to hypothermia of the human body, making it easy to catch colds, frostbite and other diseases. [0003] Vortex tube (VORTEX TUBE), also known as vortex tube. When the compressed gas enters the vortex tube, it flows to one side in a high-speed rotation. During the movement ...

AI Technical Summary

Problems solved by technology

[0005] The vortex tube used for the separation of hot and cold gases used in existing temperature control clothing usually adopts a single-channel vortex tube, and its inlet section is composed of a straight tube and a circular channel with equal cross-section. The compressed gas enters through the straight tube and the circular channel successively. For the nozzle, because the flow section changes suddenly before and after the connection between the straight pipe and the circular channel, the separation of the air flow is caused, resulting in flow loss. At the same time, the cross-sectional area of ​​the circular ring is equal. There is a large change in the airflow velocity, resulting in local vortices
