Abstract:
A boiling and cooling apparatus comprising:a refrigerant tank for maintaining a liquid refrigerant for boiling when it receives heat from a heating body; a radiator which receives refrigerant vapor boiled in said refrigerant tank, said radiator cooling refrigerant vapor to form said liquid refrigerant by exchanging heat with an external fluid; wherein said radiator includes a first passage for receiving said refrigerant vapor and a second passage for returning condensed liquid to aid refrigerant tank, said radiator having an upper space which provides communication between said first passage and said second passage, whereby said refrigerant vapor is guided to flow preferentially into said first passage, wherein said refrigerant tank is positioned substantially horizontal with respect to said radiator, wherein an upper end opening of said refrigerant tank is positioned under an opening of said first passage; and a refrigerant flow control plate interposed below an upper end opening of said refrigerant tank, said refrigerant vapor flowing from said upper opening of said refrigerant tank, said refrigerant vapor flowing from said upper opening of said refrigerant tank to said radiator, said control plate guiding said refrigerant vapor to flow from said upper end opening of said refrigerant tank into said first passage and substantially preventing said refrigerant vapor from flowing into said second passage; wherein said control plate has a first plate end attached to said refrigerant tank and second plate end suspended below said first passage of said radiator.
