Abstract

The present invention relates to a vehicle lower portion structure comprising: a housing provided on the vehicle lower side of a vehicle and having a mounting portion on which a battery is mounted; a refrigerant flow path which is provided on the vehicle lower side of the housing and which is capable of exchanging heat between the battery on the mounting part and a refrigerant; and an inflow / outflow part which communicates with the refrigerant flow path from the upper side of the vehicle and through which the refrigerant can flow in or out between the outside of the refrigerant flow path and the refrigerant flow path.

Description

technical field [0001] The present disclosure relates to a vehicle lower portion structure in which a battery case is arranged on the vehicle lower side of the vehicle. Background technique [0002] For example, in the underfloor unit disclosed in Japanese Patent Application Laid-Open No. 2015-224027, the cross-sectional shape of the cooling duct is, for example, a substantially U-shaped shape that opens toward the upper side of the vehicle. A support plate constituting the base body is arranged on the opening side of the cooling duct, and the opening side of the cooling duct is closed by the support plate. In addition, the base body is provided with a substantially flat armor plate (protector). In the first embodiment of Japanese Patent Application Laid-Open No. 2015-224027, the cooling duct is arranged inside the groove formed in the armor plate, and in the second embodiment of Japanese Patent Application Laid-Open No. 2015-224027, the armor plate is provided in the secon...
