Heat radiating fin plates in a curved shape are radially arranged on a heat radiating surface of a heat transfer plate, and a space is provided so as to be surrounded by inner edges of the heat radiating fin plates. The heat radiating fin plates have sidewalls formed with projections.
Claims12
A heat radiating plate comprising:
- a heat transfer plate;
- and
- a plurality of heat radiating fins formed on a surface of the heat transfer plate, wherein
- the heat radiating fins are formed in a curved shape and are arranged in a radial pattern on the heat transfer plate,
- a space is provided on the surface on the heat transfer plate so as to be surrounded by inward edges of the heat radiating fins,
- the heat radiating fins have at least one side wall formed with a plurality of projections,
- the projections are formed on inner and outer side walls of the heat radiating fins, and
- the projections on the inner side walls are higher than those on the outer side walls in corresponding order.
A heat radiating plate comprising:
- a heat transfer plate;
- and
- a plurality of heat radiating fins formed on a surface of the heat transfer plate, wherein
- the heat radiating fins are formed in a curved shape and are arranged in a radial pattern on the heat transfer plate,
- a space is provided on the surface of the heat transfer plate so as to be surrounded by inward edges of the heat radiating fins,
- the heat radiating fins have a side wall formed with a plurality of projections, and
- the projections have a height gradually increased from an inward portion toward an outward portion of the heat radiating fins.
A heat radiating plate comprising:
- a heat transfer plate;
- and
- a plurality of heat radiating fins arranged in a radial pattern on a surface of said heat transfer plate such that adjacent heat radiating fins define a coolant passage extending between a coolant inlet and coolant outlet, each heat radiating fin having a curved shape and including a plurality of projections extending from at least one side wall surface thereof in a direction transverse to said coolant passage, wherein
- each projection generates a vortex on a downstream side of the projection as coolant flows through the coolant passage in a direction from the coolant inlet to the coolant outlet, the vortex causing an increase in heat transfer rate between adjacent projections, and
- the projections have a height gradually increasing from an inward portion toward an outward portion of the heat radiating fins.
A heat radiating plate comprising:
- a heat transfer plate;
- and
- a plurality of heat radiating fins arranged in a radial pattern on a surface of said heat transfer plate such that adjacent heat radiating fins define a coolant passage extending between a coolant inlet and coolant outlet, each heat radiating fin having a curved shape and including a plurality of projections extending from at least one side wall surface thereof in a direction transverse to said coolant passage, wherein
- each projection generates a vortex on a downstream side of the projection as coolant flows through the coolant passage in a direction from the coolant inlet to the coolant outlet, the vortex causing an increase in heat transfer rate between adjacent projections, projections are formed on inner and outer side wall surfaces of the heat radiating fins, and the projections on the inner side wall surface are higher than the projections on the outer side wall surface in corresponding order.
A heat radiating plate comprising:
- a heat transfer plate;
- and
- a plurality of heat radiating fins arranged in a radial pattern on a surface of said heat transfer plate so that adjacent heat radiating fins define a coolant passage extending between a coolant inlet and coolant outlet, each heat radiating fin including a plurality of projections extending perpendicularly from at least one side wall surface thereof, wherein
- said plurality of projections are spaced apart from each other along said side wall surface so that coolant flowing through said coolant passage in a direction from said coolant inlet to said coolant outlet exfoliates from said side wall surface and readheres to said side wall surface between adjacent projections, and
- the projections have a height gradually increasing from an inward portion toward an outward portion of the heat radiating fins.
