摘要

针对机动车辆尤其是混合动力车辆存在的多元化热需求，本研究提出并实验验证了一种耦合热驱动吸附式制冷与相变储冷的先进热管理系统。该系统以发动机尾气余热为驱动热源，利用金属卤化物(氯化锶/氯化锰复合吸附剂)与氨工质对的可逆吸附-脱附反应实现热驱动制冷，结合相变储冷材料实现冷能的存储与稳定可控释放；同时，吸附过程可产生稳定的热能输出，进而将尾气余热有效转换为冷热能灵活利用，降低车辆热管理能耗。仿真实验表明，未采用相变储冷时，系统的制冷功率不稳定，总的制冷量随着加热温度和流量增加而增加。根据仿真结果搭建实验台并测试了典型工况下系统的性能。结果表明，在夏季环境(温度为37℃)工况下，储冷后相变材料可稳定以平均1.37 kW的制冷功率输出温度为15~20℃的冷能，其储冷能量密度和功率密度分别为247 kJ/kg和47.2 kW/m

，系统性能系数(COP)为0.234；在冬季-30~5℃的低温下，系统最高以平均1.69 kW的制热功率稳定输出温度为60℃的热能，吸附剂的储热能量密度和功率密度分别为744.6 kJ/kg和60.4 kW/m

，此热能可用于发动机的冷启动暖机、座舱控温等。本研究为提升机动车辆全域环境适应性、提高车辆能源综合利用率提供了潜在的技术路径。

Abstract

In response to the diverse thermal demands of motor vehicles

particularly hybrid electric vehicles

this study proposes and experimentally validates an advanced thermal management system that couples thermally driven adsorption refrigeration with phase change cold storage. The system utilizes waste heat from engine exhaust as the driving heat source

leveraging reversible adsorption-desorption reactions between a metal halide composite adsorbent

such as strontium chloride/manganese chloride

and an ammonia working pair to realize thermally driven cooling. This process is integrated with phase change cold storage materials to enable the storage and regulated release of cooling energy. At the same time

the adsorption process generates stable and controllable thermal output

thereby effectively converting exhaust waste heat into flexible cooling and heating capabilities and reducing the energy consumption of vehicle thermal management. Simulation and experimental results indicate that

in the absence of phase change materials

the cooling power becomes highly unstable

whereas the total cooling capacity increases with increasing heating temperature and flow rate. Under summer conditions with an ambient temperature of 37℃

the system supplies cooling energy at 15—20℃ with an average power of 1.37 kW. The phase change material provides a cold storage energy density of 247 kJ/kg and a power density of 47.2 kW/m

with a system coefficient of performance of 0.234. Under winter conditions ranging from -30℃ to 5℃

the system delivers heating at temperatures of up to 60℃ with an average power of 1.69 kW. The adsorbent exhibits a thermal energy storage density of 744.6 kJ/kg and a power density of 60.4 kW/m

supplying heat for engine cold starts and Warm-up and cabin temperature regulation. This work provides a potential technical pathway for improving all-climate adaptability and overall energy utilization efficiency in motor vehicles.
