A motor vehicle cabin heater is provided. The motor vehicle cabin heater 10 has first 20 and second 30 liquid to air heat exchangers mounted in a housing 15 so close to each other such that air flowssequentially through the first 20 and second 30 liquid to air heat exchangers before flowing to a cabin 6 of a motor vehicle 5. The motor vehicle cabin heater 10 forms a part of a motor vehicle 5. Thefirst 20 liquid to air heat exchanger receives a supply of heat exchange liquid from a charge air cooler 81 of an engine charge air cooling system 8 and the second 30 liquid to air heat exchanger receives a supply of heat exchange liquid from a main engine cooling system 9. The first 20 liquid to air heat exchanger provides cabin heating before the second 30 liquid to air heat exchanger and aidswarms up of the heat exchange liquid in the main engine cooling system.
本申请涉及机动车辆舱室加热器。公开了机动车辆舱室加热器10,其具有第一和第二液体‑空气热交换器20和30,第一和第二液体‑空气热交换器20和30彼此紧密靠近地安装在壳体15内,使得空气能够在流向机动车辆5的舱室6之前顺序地流过第一和第二液体‑空气热交换器20和30,舱室加热器10形成机动车辆5的一部分。第一液体‑空气热交换器20接收来自发动机增压空气冷却系统8的增压空气冷却器81的热交换液体的供应并且第二液体‑空气热交换器30接收来自主发动机冷却系统9的热交换液体的供应。第一液体‑空气热交换器20能够在第二液体‑空气热交换器30之前提供舱室加热并且有助于预热主发动机冷却系统9中的热交换液体。
