In summer, the high temperature inside vehicles is a problem, because cooling a vehicle parked under the scorching sun is both time and energy consuming. Herein, a portable solar‐powered cooling system (SPCS) is proposed based on a foldable‐flower mechanism and wireless power transfer (WPT) technology. The proposed system consists of three main parts: a solar foldable‐flower module (SFFM), an energy transfer module, and a temperature control module. The SFFM is a novel foldable mechanism that achieves a high space utilization through a rotating process and a folding process, like a flower opening its petals. The SFFM, equipped with photovoltaic (PV) cells, collects solar energy and converts it into electricity. The energy transfer module stores electricity from the SFFM in a supercapacitor via a WPT unit. The temperature control module achieves automatic temperature regulation using a cooling device. Experimental results show that output power reaches up to 7.571 W with a load resistor of 5 Ω, whereas the efficiency of the WPT reaches up to 73.6% with a load resistor of 15 Ω. Moreover, thermal simulation results illustrate that the proposed system achieves an average temperature reduction of 27.45 °C, making it feasible and effective to cool a hot vehicle cabin.

基于折叠式花架机构和无线功率传递技术的高效,便携式太阳能冷却系统,用于车厢

在夏天,车辆内部的高温是个问题,因为冷却停在烈日下的车辆既费时又耗能。在此,提出了一种基于可折叠花朵机构和无线功率传输(WPT)技术的便携式太阳能冷却系统(SPCS)。拟议的系统包括三个主要部分:太阳能可折叠花模块(SFFM),能量传输模块和温度控制模块。SFFM是一种新颖的可折叠机制,通过旋转过程和折叠过程(例如,打开花瓣的花朵)来实现较高的空间利用率。配备有光伏(PV)电池的SFFM收集太阳能并将其转换为电能。能量传输模块通过WPT单元将SFFM中的电能存储在超级电容器中。温度控制模块使用冷却装置实现自动温度调节。实验结果表明,负载电阻为5Ω时,输出功率高达7.571 W,而负载电阻为15Ω时,WPT的效率高达73.6%。此外,热仿真结果表明,所提出的系统可将平均温度降低27.45°C,从而为热车厢降温提供了切实可行的方法。
