Technical Field

The utility model belongs to the technical field of refrigeration garments, and particularly relates to a thermoelectric refrigerator array type heat pipe temperature control partition accurate temperature control thermal management system for a micro-environment in a protective garment based on a thermoelectric refrigerator array.

Background

Currently, many workers in industries such as medical, mining, metallurgy, etc. are required to work with protective clothing. The protective clothing has the characteristics of heat insulation, water resistance, harmful substance blocking and the like, can effectively block the harm of adverse environment to human body, but can also prevent the normal heat dissipation and moisture removal of the human body, thereby increasing the load of a human body heat regulation system, leading workers to generate heat stress phenomenon in severe cases, reducing the working efficiency, and leading to chronic diseases for a long time. Therefore, the problem of heat dissipation of the microenvironment inside the protective clothing is increasingly emphasized. In order to increase the thermal comfort of protective clothing and reduce the risk of thermal stress for workers, it is imperative to develop a thermal management system for temperature control in protective clothing.

At present, the temperature control system of the protective clothing mostly adopts an integrated active gas or liquid cooling clothing technology to collect heat generated by a human body, the cooling working medium in a mechanical pump driving pipeline transmits the waste heat of the human body to an external cold source of the protective clothing, then the cooling working medium enters the cooling clothing again after heat dissipation, and the long-time temperature control of the human body is realized through the circulation. The cooling suit adopts continuous flexible pipeline to make up on cooling suit cloth with the mode that the return circuit encircles, and the return circuit can warp wantonly, and the arrangement is nimble, is fit for human used heat to collect, is convenient for dress, and multiplicable return circuit convection current area of contact improves human heat production collection efficiency. However, the following problems still exist in the thermal management and temperature control system of the fluid loop:

1. when the fluid loop is arranged outside the trunk of a human body, a gap exists between adjacent pipelines, when the heat transfer working medium flows through the pipelines, the skin temperature close to the pipelines is lower, the skin temperature at the gap is higher, and the supercooling reaction of the human body is easily caused because the pipelines are arranged alternately so that the temperature on the surface of the trunk skin is in pulse fluctuation.

2. In the process of collecting heat generated by a human body, the fluid loop heat management temperature control system has the advantages that due to the continuity of the pipeline, the temperature of a cooling working medium at the inlet of the pipeline is low, the temperature difference between the skin of the trunk is large, the heat generated by the human body is good in collecting effect, and the temperature of the skin of the trunk at the inlet is low; along with cooling working medium flows in the pipeline, constantly collects human heat production, and the temperature is higher and higher, and at the return circuit exit, the temperature rises to the highest, and the heat is collected the effect variation, leads to the temperature of exit truck skin to be far higher than the temperature of import department, influences the homogeneity of temperature control, influences the thermal comfort of cooling suit.

3. Because the basic metabolic rate of each part of the body is different, the heat production of different parts is inconsistent; the heat sensitivity of each part is inconsistent, the corresponding comfortable temperature value is inconsistent, and the intrinsic temperature control requirements of the human body need to carry out respective heat management control on each part. However, for the integrated fluid loop heat management temperature control system, the heat generated by the human body is collected and the temperature control is completed mainly by integrally adjusting the flow and the temperature of the working medium, and the partitioned waste heat collection and the partitioned temperature accurate control of the trunk are difficult to realize.

The present invention has been made in view of this situation.
