Claims (1)

[Scope of Claim for Utility Model Registration] 1. A case that has a cold air outlet that communicates with a cold air duct provided on the roof of a vehicle through a connecting duct, and that contains refrigeration cycle components in a case installed on the roof of the vehicle. , which houses at least a refrigerant condenser and a refrigerant evaporator, and connects a refrigerant compressor driven by an engine mounted at the bottom of the vehicle body and the components of the refrigeration cycle housed in the case through refrigerant piping. In the vehicle cooling system, the refrigerant compressor and the components of the refrigeration cycle housed in the case are connected by a case-side refrigerant pipe arranged in the case, the cold air outlet,
A connection duct, a cold air duct, a vehicle-side refrigerant pipe connected to the refrigerant compressor through a space between an outer plate and an inner plate of the vehicle body, and a vehicle-side refrigerant pipe and a case-side refrigerant pipe connected to the roof of the vehicle body. A cooling device for a vehicle, comprising a connecting portion that connects the case near a joint surface with a bottom plate. 2. The vehicle cooling system according to claim 1, wherein the connecting duct has an inspection lid that can be opened and closed on the side of the vehicle compartment.
