This application discloses a housing
assembly, a
temperature control system, and a vehicle. The housing
assembly includes a housing and a first
pipe. The housing includes a receiving cavity, and an air inlet and an external air outlet communicating with the receiving cavity. The first
pipe is connected to the housing and configured to connect the
temperature control duct of the vehicle's
air conditioning assembly and the air inlet, thereby connecting the
temperature control duct of the
air conditioning assembly and the external air outlet as a first ventilation channel. In this embodiment, cold or hot air from the temperature control duct of the vehicle's
air conditioning assembly can enter the receiving cavity of the housing through the first
pipe to cool or heat the receiving cavity, thereby regulating the temperature inside the receiving cavity. Simultaneously, air inside the receiving cavity can be exhausted to the outside of the vehicle through the external air outlet, achieving ventilation and
air exchange within the receiving cavity, preventing odorous gases from entering the passenger compartment and affecting the passenger compartment environment, thus realizing a smart
cockpit that better meets
user needs.
