Patent ID: 7483261

Claim:
A cooling device for an electronic equipment, comprising: a cooling panel including a bottom heat radiation plate and a top heat radiation plate, at least one of which is provided with a groove, said bottom heat radiation plate and top heat radiation plate being bonded together to form a passage of refrigerant; and a circulation pump fixed onto said cooling panel to circulate said refrigerant through said passage for radiating heat transferred to said cooling panel, wherein: said top heat radiation plate is provide with an inlet port through which said refrigerant flows from said passage to said circulation pump and an outlet port through which said refrigerant flows from said circulation pump to said passage; and said circulation pump is fixed onto said inlet port and outlet port; wherein said circulation pump is a piezoelectric pump, and wherein said piezoelectric pump includes a pump housing defining a pump chamber receiving therein a piezoelectric vibration plate, and said pump housing is fixed onto said cooling panel so that a discharge port and a suction port of said circulation pump are aligned with said inlet port and said outlet port, respectively.
