Abstract
A guide 2 for supporting a device in a flow of coolant includes a deflector 4 for modifying the coolant flow. The guide include apertures 6 so that the coolant can flow over both the upper and lower faces of a device, for example a printed circuit board 24.
Claims13
A guide member for the support of a circuit board in a flow of gaseous coolant within an enclosure, comprising:
- a base;
- a wall extending from said base;
- a channel, formed in a rear side of said wall and spaced from said base, for the reception of an edge of said circuit board, said wall comprising, between said channel and said base, slots for the passage of said flow of coolant over a first surface of said circuit board;
- and
- a wedge shaped deflector extending from a front side of said wall upstream into said flow and for diverting a selected proportion of said flow over a second surface of said circuit board.
2 more elements
An apparatus comprising:
- an enclosure;
- a circuit board in the enclosure;
- a fan for generating a flow of gaseous coolant past the circuit board, and;
- a first guide for supporting said circuit board in a plane generally parallel to said flow of gaseous coolant, said first guide comprising:
- a first base,
- a first wall extending from said first base and having first slots for the passage of said flow of coolant over a first surface of said circuit board,
- a first channel for the reception of said circuit board, and
- a first wedge shaped deflector extending from said first wall upstream into said flow and for diverting a selected proportion of said flow over a second surface of said circuit board.
