A cooling device for a vehicle charging inlet according to an application example of the present invention is a cooling device for a vehicle charging inlet of a vehicle driven by power of a battery charged by power supplied from an external power supply device. a power receiving terminal connected to a power feeding terminal of an external power feeding device; a housing that holds the power receiving terminal and is arranged in the vehicle charging inlet; and a charging inlet cooling circuit supplied with a coolant , the housing is formed with a flow path for the charging inlet cooling circuit .
A vehicle charging inlet cooling device according to another application example of the present invention is a vehicle charging inlet cooling device for a vehicle driven by power of a battery charged by power supplied from an external power supply device. a power receiving terminal that is connected to a power feeding terminal of the external power feeding device during charging; a housing that holds the power receiving terminal and is arranged in the vehicle charging inlet; a charging inlet cooling circuit supplied with a refrigerant; a cooling plate installed across the housing that holds the terminals, wherein the flow path of the charging inlet cooling circuit is formed inside the cooling plate.
上記適用例に係る車両用充電インレットの冷却装置によれば、充電インレットのハウジングに充電インレット冷却回路の冷媒が供給される流路が形成されていることで、外部給電装置の給電端子が充電インレットの受電端子と接続される充電時において、受電端子を保持するハウジングの流路を冷媒が流通し、ハウジングが保持する受電端子を冷却することができる。
また上記他の適用例に係る車両用充電インレットの冷却装置によれば、冷却プレートがハウジングに跨って設置され、冷却プレートに内部流路が形成されていることで、ハウジングが保持する受電端子を冷却することができる。
このように充電時に最も発熱量が大きい充電インレットの端子部分近傍に冷却用の流路を形成することで、より確実に充電インレットにおける発熱を抑制し、急速充電中に発生する充電制限の頻度を抑制することができる。
According to the vehicle charging inlet cooling device according to the application example, the flow path through which the refrigerant of the charging inlet cooling circuit is supplied is formed in the housing of the charging inlet. During charging when connected to the power receiving terminal of the inlet, coolant flows through the flow path of the housing holding the power receiving terminal, and the power receiving terminal held by the housing can be cooled.
Further, according to the vehicle charging inlet cooling device according to the other application example, the cooling plate is installed across the housing, and the internal flow path is formed in the cooling plate, so that the power receiving terminal held by the housing can be cooled. Allow to cool.
By forming cooling channels near the terminals of the charging inlet, which generate the most heat during charging, heat generation in the charging inlet can be suppressed more reliably, and the frequency of charging restrictions that occur during rapid charging can be reduced. can be suppressed.
