Abstract
In a cooling device for a heat source according to the present invention, header is arranged on the downstream side of an inlet port i.e. on the side of holes opposite to that of the heat source, a heat source is arranged on the outside face of a heat sink and holes are provided that spray fluid towards the back face of the heat sink, outlet ports being provided fewer than the number of holes. Thanks to the arrangement of header on the side of holes opposite to that of the heat source, no large differences are generated in the flow rate of the holes; thus, the heat conduction rate when the flow from holes collides with the back face of the heat sink is practically uniform and the cooling performance of the heat sink, with which the flow collides, at the back of the heat source is practically uniform.
Claims16
A cooling device for a heat source, comprising:
- (1) a heat sink including a coolant, said heat sink comprising:
- (a) a first heat sink member with a heat source arranged at an outer surface of said heat sink;
- and
- (b) a second heat sink member provided with a plurality of holes, said coolant that cools said heat source being made to pass through said holes;
- (2) a header configured to an opposite side to said first heat sink member about said second heat sink member as axis;
- (3) an inlet port whereby said coolant is made to flow into a first space surrounded by said header and said second heat sink member;
- (4) an outlet port whereby said coolant in a second space surrounded by said first heat sink member and second heat sink member is made to flow out;
- and
- (5) an upright plate provided on a downstream side of said header.
A cooling device for a heat source comprising:
- a header wherein one or a plurality of holes are respectively provided in wall faces on both sides;
- a heat sink outside wall where a heat source is arranged on an outer surface with gaps being provided on both sides of said header;
- an inlet port whereby coolant flows into said header;
- and
- an outlet port whereby said coolant within said heat sink flows out.
