Water circulation heating dry-state dummy

Abstract

The invention discloses a new dry-state dummy device. The device mainly comprises a skeleton, joints, a water circulation heating system and a control system, wherein the physical dimensions of the skeleton and the joints of the human normal body can be stimulated from an appearance view, and the movement ability of the three joints including shoulders, the hip and the knee can be used as a main medium which can perform heat exchange with the environment. The water circulation heating system is of a core structure, and a mixed proportion of cold water and hot water with constant temperature can be controlled so that mixed water flows in a circulating pipeline; the heat energy is released to the environment under the assistance of the skeleton and the joints; the control system can be used for measuring the flow of the hot water and the cold water and the skin surface temperature of the dummy in real time; the flow of the hot water and the cold water and the skin surface temperature of the dummy can be converted into heat dissipating capacity by calculation, and the water circulation heating system can be assisted to control the temperature. The water circulation heating dry-state dummy can be applied to a calibration measurement instrument for simulating the human body temperature change and evaluating the indoor space temperature comfort. Compared with the traditional electric heating dummy, the water circulation heating dry-state dummy has the main advantages that the dummy can be adjusted in a cold and hot wide temperature area and is relatively easy and convenient to operate.

Description

(1) Technical field [0001] The invention relates to a dry warm body dummy device which uses a water circulation heating method to simulate the surface temperature field of a human body. The device can be switched between a standing posture and a sitting posture. (2) Background technology [0002] The thermal manikin used for the comfort evaluation of indoor environment requires the mannequin to have similar heating characteristics and temperature field distribution as the human body. This requires that the dummy has universal applicability in a wide temperature range of cold and hot. At present, most thermal dummies use electric heating to heat the surface of the dummy body. The main disadvantage of this heating method is that it cannot simulate the cooling process. One solution is to add a cooling structure (usually liquid cooling), but there is an incompatibility between electricity and liquid, which will reduce the working stability and life of the dummy. The invention ...

At present, most thermal dummies use electric heating to heat the surface of the dummy body. The main disadvantage of this heating method is that it cannot simulate the cooling process.

One solution is to add a set of cooling structure (usually liquid cooling), but there is an incompatibility between electricity and liquid, which will reduce the working stability and life of the dummy
