Document Type and Number:
WIPO Patent Application WO/2020/261655
Kind Code:
A1
Abstract:
Provided is a vehicle-mounted electronic device comprising: an electronic component (31) that is disposed on the passenger compartment (100a)-side of the ceiling (11) of a vehicle (100); and a cooling unit (34) that cools the electronic component. The cooling unit includes: a pipe (51) through which the refrigerant flows; a heat absorber (52) which connects to the pipe and allows heat to be exchanged between the inflowing refrigerant and the electronic component so that heat is absorbed from the electronic component; a heat radiator (53) which connects to the pipe and allows heat to be exchanged between the refrigerant that has passed through the heat absorber and the air in the lower portion of the passenger compartment so that the heat is radiated to the lower portion of the passenger compartment; and a pump (54) which connects to the pipe and causes the refrigerant to be circulated between the heat radiator and the heat absorber.
