一种汽车热电暖风空调

目前的车用空调，制冷方面一般采用传统的压缩机制冷技术；制热方面，传统汽车使用发动机余热，纯电动汽车使用PTC加热，为了提高冷车启动制热响应速度，部分传统汽车也加装了PTC加热器。冬季挡风玻璃的快速除霜除雾和车内制热，必须使用大功率PTC加热器，加剧了汽车功耗，特别是对于纯电动汽车，续航里程将降低30％以上。汽车厂商也在逐渐推广使用热泵型汽车空调，能效虽然能够提高，但低温制热能力受到条件限制，还需要进一步改进，并且还存在制冷剂的泄漏、爆炸、以及成本较高等问题。本实用新型提供一种汽车热电暖风空调,包括水泵、鼓风机和暖风芯体;其中,所述暖风芯体位于所述鼓风机与车舱内出风口之间的导风通道内,包括热电器件、散热翅片和水通道换热器,所述热电器件加热所述暖风芯体中的散热翅片,所述水通道换热器与汽车的车载冷却系统相连并形成回路。本实用新型的汽车热电暖风空调结构简单、能耗低、适合大功率加热,可实现汽车挡风玻璃的快速除霜除雾,并为驾乘人员提供舒适的环境。主要记录了不同工况下PTC暖风空调与热电暖风空调性能对比、实施形态的汽车热电暖风空调的结构以及汽车热电暖风空调中的热电器件与散热翅片组件立体图等相关数据，数据量740KB。

Most current vehicle air conditioners adopt traditional compressor-based refrigeration technology for cooling. For heating, conventional vehicles use engine waste heat, while battery electric vehicles (BEVs) rely on PTC heating. To enhance the heating response speed during cold starts, some conventional vehicles have also installed additional PTC heaters. Rapid defrosting and defogging of windshields and in-cabin heating in winter necessitate high-power PTC heaters, which exacerbate vehicle power consumption. Particularly for BEVs, the driving range will be reduced by more than 30%. Automakers are gradually promoting heat pump vehicle air conditioners, which can improve energy efficiency but have limited low-temperature heating capacity and require further optimization. Additionally, such systems face issues including refrigerant leakage, explosion risks, and high production costs. This utility model patent proposes a thermoelectric warm-air air conditioner for vehicles, which comprises a water pump, blower fan, and heating core. The heating core is positioned in the air guide channel between the blower fan and the cabin air outlets, and consists of thermoelectric devices, heat dissipation fins, and a water-channel heat exchanger. The thermoelectric devices heat the heat dissipation fins inside the heating core, while the water-channel heat exchanger is connected to the vehicle-mounted cooling system to form a closed loop. This thermoelectric warm-air air conditioner featured in this utility model has a simple structure, low energy consumption, and is suitable for high-power heating. It can achieve rapid defrosting and defogging of vehicle windshields and provide a comfortable environment for both drivers and passengers. This dataset mainly records relevant data including performance comparisons between PTC warm-air air conditioners and thermoelectric warm-air air conditioners under different operating conditions, the structure of the practical embodiment of the vehicle thermoelectric warm-air air conditioner, and stereoscopic diagrams of the thermoelectric device and heat dissipation fin assembly in the vehicle thermoelectric warm-air air conditioner, with a total data size of 740 KB.
