Personal thermal comfort device based on Peltier effect

Abstract

The invention discloses a personal thermal comfort device based on the Peltier effect. The personal thermal comfort device comprises a thermoelectric module, a cooling fan, an external packaging module, a micro air blower and a micro hose network. Heat dissipation plates are attached to the hot side and the cold side of the thermoelectric module correspondingly, the thermoelectric module and the heat dissipation fan form an integrated structure through an external packaging module with a channel, one end of the integrated structure is connected with the micro air blower, and the other end of the integrated structure is connected with the micro hose network. The micro air blower provides cold or hot air flow and leads to special clothes through the micro hose network, and a needed heat source or cold source is provided for the whole human body. According to the personal thermal comfort device based on the Peltier effect, the specific thermoelectric module, the heat dissipation fan and a heat dissipation plate are selected and combined into a detachable and portable thermoelectric conversion device. The micro air blower is selected to feed cold energy into the special clothes. The whole set of equipment has the advantages of portability, excellent energy efficiency and temperature controllability. A local thermal environment can be established by combining with a building heating and ventilating central air-conditioning system, and the personal thermal comfort is improved.

Description

Technical field[0001]The present invention relates to a personal thermal comfort device in the context of a personal thermal management control device based on Parli effect, which is a thermoelectric conversion technology.Background technique[0002]The earliest personal thermal management device is in order to adapt to the needs of modern warfare, solve the problem of physical energy consumption in the high-heat environment due to the physical energy consumption, obstacles, absence of unlock, brain reactive, etc. The type of clothing currently used in personal thermal management is diverse, and one is to heat or cool by liquid or air, and a class is to add a phase change material to generate a chemical reaction for energy conversion.[0003]Equipment for providing heating and cooling at home and abroad also has research, and thermoelectric cooling has quickly become practical technologies suitable for multiple types of electronic devices. The equipment in today's market is also very co...

Problems solved by technology

[0004] Combined with building heating and ventilation systems to expand the indoor temperature adjustment range, a set of personal thermal management devices jointly developed by the University of Colorado Boulder and the Thermal Fluid Science and Engineering Laboratory of Xi'an Jiaotong University in 2018 has taken shape. The heat sink, thermoelectric module, and small heat dissipation fan are combined to form a simple thermoelectric conversion module, but the effect is not very significant, and the temperature adjustment range is too small and uncontrollable
