具體地,如第8圖所示,前固定座71包括:底壁71a和周壁71b,充電連接件10固定在底壁71a上,周壁71b上設置有出風口71c。也就是說,送風件25吹向冷卻艙70內的冷風可以從出風口71c吹出,這樣吹出後的冷風可以再次與充電連接件10接觸,從而可以更好地帶走充電連接件10的熱量。
Specifically, as shown in FIG. 8, the
其中,如第10圖所示,充電連接件10可以包括:殼體14和接線端子11,接線端子11固定在殼體14內,殼體14的內周形成有通風孔15。由此,在充電連接件10與充電槍對接時,冷風通過進風口71d進入冷卻艙70,然後冷風從出風口71c流出,然後從出風口71c吹出的冷風可以流過通風孔15,將充電連接件10包裹住,這樣冷風不僅可以冷卻充電連接件10,還可以冷卻充電槍,從而可以更好的降低充電連接件10的工作溫度。
As shown in FIG. 10, the charging
可選地,如第10圖所示,通風孔15可以為複數,而且複數通風孔15在殼體14的內周周向分佈。如此佈置的複數通風孔15可以使得殼體14佈局合理,而且可以保證接線端子11的周向均流動有冷風,從而可以進一步地提升充電連接件10處的換熱效果。
Alternatively, as shown in FIG. 10, the vent holes 15 may be plural, and the plural vent holes 15 are distributed circumferentially in the inner circumference of the
可選地,充電裝置100還可以包括:控制器、充電狀態檢測模組和溫度感測器,溫度感測器用於檢測充電連接件10的溫度,溫度感測器與控制器電連接,控制器適於在充電狀態檢測模組檢測到車輛充電時控制送風件25工作,以及適於在溫度感測器檢測到的溫度值大於預定值時控制壓縮機21工作。也就是說,送風件25和壓縮機21可以不同時工作,例如,在溫度較低且充電連接件10剛開始進行充電時,送風件25開始工作,可以提供給充電連接件10一定流量的常溫風,從而可以減緩充電連接件10的工作溫度不上升,在充電連接件10的溫度上升至預定溫度時,壓縮機21再開始工作,蒸發器23先與空氣換熱,空氣再與充電連接件10換熱,從而可以快速降低充電連接件10的工作溫度。
