An in-vehicle electronic device includes an electronic component (31) provided between a roof panel (101) of a vehicle and a ceiling liner (102) of a vehicle compartment (100a), and a cooling unit (40) for cooling the electronic component (31), the cooling unit (40) including: rubber hoses (71, 72) through which a refrigerant having a volume increased due to a temperature rise flows; a heat absorption unit (50) to which the rubber hoses (71, 72) are connected, into which the refrigerant flows, and which absorbs heat from the electronic component (31) by exchanging heat between the refrigerant that flows in and the electronic component (31); a heat dissipation unit (60) that is disposed in the vehicle compartment (100a), is connected to the rubber hoses (71, 72) and into which a refrigerant flows, exchanges heat between the refrigerant that has passed through the heat absorption unit (50) and air within the vehicle compartment (100a), and dissipates heat of the refrigerant to the vehicle compartment (100a); and check valves (73, 74) that are disposed in a flow path through which the refrigerant flows and that are opened by an increase in the pressure of the refrigerant.

    本发明提供一种车载用电子装置,包含:设置在车辆的车顶板(101)与车室(100a)的顶棚内衬(102)之间的电子部件(31)、以及冷却电子部件(31)的冷却部(40),冷却部(40)包含:橡胶软管(71、72),供由于温度上升而体积增加的制冷剂流动;吸热部(50),被连接橡胶软管(71、72)来供制冷剂流入,在流入的制冷剂与电子部件(31)之间进行热交换,而从电子部件(31)吸热;散热部(60),配置于车室(100a),被连接橡胶软管(71、72)而供制冷剂流入,使通过了吸热部(50)的制冷剂和车室(100a)内的空气进行热交换,将制冷剂的热量向车室(100a)散热;以及止回阀(73、74),配置于制冷剂流动的流路,通过制冷剂的压力上升而被打开。
