Abstract

The invention discloses a partition accurate heat management system in a protective garment based on a thermoelectric refrigerating unit array. The partition accurate heat management system comprises a thermoelectric refrigerating unit array partition heat management temperature control garment body, an open-loop partition air cooling auxiliary heat removal system and a partition temperature control garment heat management control system, the thermoelectric refrigerating unit array partition heat management temperature control garment body comprises an inner lining layer, a middle layer and an outer lining layer from inside to outside, and collection, transmission and dissipation of heat generated by the body are achieved. The partition temperature control garment heat management control system comprises a controller, a direct-current adjustable power supply, a trunk temperature sensor and a plurality of thermoelectric refrigerating unit array groups, temperature detection of different parts of the trunk is completed, and the working current of a thermoelectric refrigerating unit module is adjusted in real time. According to different heat produced by different parts of the human body, the thermoelectric refrigerating unit array group is adopted to dynamically adjust the temperature of different blocks of the trunk, the instinct temperature control requirement of the body is met more comprehensively through subarea accurate temperature control, and the system is more humanized.

Description

technical field [0001] The invention belongs to the technical field of refrigeration clothing, and in particular relates to a thermoelectric refrigerator array-type heat pipe temperature control zone precise temperature control heat management system for a microenvironment in a protective clothing based on a thermoelectric refrigerator array. Background technique [0002] Currently, many workers in industries such as medical, mining, metallurgy, etc. need to wear protective clothing to work. Protective clothing has the characteristics of heat insulation, waterproof and blocking harmful substances, which can effectively prevent the harm to the human body from adverse environments, but it also hinders the normal heat dissipation and dehumidification of the human body, which increases the load on the human body's thermal regulation system. This can lead to heat stress among workers, reducing work efficiency and leading to chronic diseases in the long run. Therefore, more and m...

Problems solved by technology

[0004] 1. When the fluid circuit is arranged outside the human torso, there is a gap between adjacent pipelines. When the heat transfer medium flows through the pipeline, the skin temperature near the pipeline is low, while the skin temperature in the gap is high. The alternate layout of the pipelines makes the temperature of the skin surface of the torso fluctuate in pulses, which is likely to cause the supercooling reaction of the human body

[0005] 2. In the process of collecting the heat produced by the human body, the heat management and temperature control system of the fluid circuit, due to the continuity of the pipeline, the temperature of the cooling medium at the entrance of the pipeline is low and the temperature difference between the skin of the trunk is large, and the heat produced by the human body is collected effectively. The temperature of the torso skin at the entrance is low; as the cooling medium flows in the pipeline, it continuously collects the heat produced by the human body, and the temperature becomes higher and higher. The temperature of the torso skin at the entrance is much higher than the temperature at the entrance, which affects the uniformity of temperature control and the thermal comfort of the cooling suit

However, for an integrated fluid circuit thermal management and temperature control system, the heat generated by the human body and temperature control are mainly collected by adjusting the flow and temperature of the working fluid as a whole, and it is difficult to achieve partitioned waste heat collection and precise temperature control of the trunk.
