Abstract

The utility model discloses a novel cooling fin which comprises a rectangular cooling bottom plate and a plurality of fins arranged on the cooling bottom plate, wherein the fins are of cylindrical structures, the fin positioned at the central position of the cooling bottom plate is perpendicular to the cooling bottom plate, and the rest of the cooling fins radiate to the rim around the cooling bottom plate. The cooling fin is arranged above a mainboard processor needing cooling or a bridge chip and directly faces a case fan horizontally, and air blown out of the case fan takes away heat of the cooling fin through the cooling fin. According to the novel cooling fin, the fins radiate to the rim around the cooling bottom plate or incline, gaps among the fins are increased, cross ventilation is optimized, cooling efficiency of a system is increased, speed of the system fan is reduced, cooling power consumption is reduced, and operation noise of the system is lowered greatly.

Description

A kind of radiating fin
Technical field
The utility model relates to heat radiator, is specifically related to a kind of radiating fin.
Background technology
Along with the quickening day by day of computer technology, the parts such as cabinet inside board, chip produce increasing heat in the course of the work, so cabinet inside has been proposed to higher heat radiation requirement for the heat dissipation equipment dispelling the heat to each parts, existing heat radiator can not meet current radiating requirements.As shown in Figure 1, existing heat radiator 1 comprises a radiating bottom plate 3 and is arranged on the some radiating fins 4 on base plate, described radiating fin is cylindrical structural, but in original heat radiator, these radiating fins are to be all vertically set on described radiating bottom plate, numerous like this radiating fin close-packed arrays together spacing are very limited, had a strong impact on radiating effect.If use original heat radiator to want to guarantee desirable radiating effect, need to improve the rotating speed of cabinet internal fan, so improve the requirement to fan performance, improved power consumption simultaneously.
Utility model content
The utility model, for the deficiencies in the prior art part, provides a kind of radiating fin simple in structure.
The utility model discloses a kind of radiating fin, its technical scheme that solve the technical problem employing is as follows: comprise radiating fin, processor on cabinet mainboard or north and south chip and case fan, described heat radiator is arranged on needs the mainboard processor of heat radiation or north and south chip top, described heat radiator laterally faces case fan simultaneously, the wind blowing out in described case fan is just taken away the heat of heat radiator by described heat radiator, described heat radiator comprises a rectangle radiating bottom plate and is arranged on the some fins on this radiating bottom plate, described fin is cylindrical structural, be positioned at the fin of described radiating bottom plate center perpendicular to radiating bottom plate, all the other fins are all inclined on described radiating bottom plate.
Further, described fin tilts to the surrounding periphery of described radiating bottom plate.
Further, from the center of described radiating bottom plate, to its surrounding periphery, the degree of tilt of described fin reduces gradually.
Further, described fin is elongated cylindrical, and the length of all fins is identical.
The beneficial effect that radiating fin disclosed in the utility model has is: this radiating fin is designed to the form that fin tilts to surrounding, space between fin is increased, optimize cross-ventilation, improve the heat dissipation of system, make system fan rotating speed reduce simultaneously, the heat radiation power consumption that has reduced system, reduces operational noise of system greatly.
Accompanying drawing explanation
Accompanying drawing 1 is described existing gelled schematic diagram;
The schematic diagram that accompanying drawing 2 is described radiating fin;
Accompanying drawing mark explanation: 1, existing heat radiator; 2, radiating fin; 3, radiating bottom plate; 4, fin.
Embodiment
Below in conjunction with accompanying drawing, radiating fin disclosed in the utility model is described in further details.
Radiating fin disclosed in the utility model, as shown in Figure 2, this radiating fin 2 comprises a radiating bottom plate 3 and is arranged on the some fins 4 on this radiating bottom plate its structure, and described radiating bottom plate is a rectangle radiating bottom plate, and described fin is cylindrical structural.In order to improve the heat dissipation of this fin heat radiator, described fin is also not all vertically set on described radiating bottom plate, described several fins tilt to the surrounding of radiating bottom plate, and described radiating fin seems on the whole, and the fin on radiating bottom plate is the structure of outwards dispersing.
Embodiment: the embodiment that heat radiator described in the utility model is chosen is as follows: its optimal design as shown in Figure 2, this radiating fin is made up of a square radiating bottom plate and several fins that are arranged on square radiating bottom plate, and described fin is the slim cylindrical construction that length is identical.Original fin heat radiator, cylindrical fin is to be all vertically set on radiating bottom plate, numerous like this fin pitch are less, affect radiating effect.In the present embodiment, in order to strengthen the cross-ventilation between fin, improve the radiating effect of this heat radiator, only be positioned at the fin of radiating bottom plate center perpendicular to radiating bottom plate, all the other fins all have inclination in various degree on radiating bottom plate, between all the other fins and radiating bottom plate, all have the acute angle angle of different sizes.Further, described fin tilts to the surrounding of described radiating bottom plate, and to its periphery, the degree of tilt of described fin reduces gradually from described radiating bottom plate center, the acute angle angle of described fin between middle mind-set periphery and the radiating bottom plate of radiating bottom plate reduces gradually.
Use heat radiator described in the utility model, be fixed in and on mainboard, need the parts of heat radiation top, such as processor, South Bridge chip or north bridge chips top, described heat radiator is laterally just to case fan, because the fin of this heat radiator is designed to the form tilting to surrounding, the wind blowing out from case fan is like this by heat radiator, and the structure of heat radiator uniqueness can be optimized cross-ventilation, heat dissipation can be improved to 30%.This fin heat radiator is designed to fin cylindrical, the cooling surface area of each fin still adopts original size, more board-like, strip fin area of dissipation is maximization, while is due to the increase in numerous fins gap, be conducive to flowing of air, increase air circulation, improved the heat dissipation of mainboard upper-part and system.So, in the situation that radiating bottom plate size is constant, under the constant prerequisite of the effective contact area of heat radiator, improved the radiating effect of fin heat radiator.Simultaneously, the structural design that fin heat radiator described in the utility model adopts fin to disperse to surrounding, also reduced from the side the heat radiation requirement to system of processor, South Bridge chip or north bridge chips, reduce system fan rotating speed, reduce system radiating power consumption, made operational noise of system greatly reduce simultaneously.
Except technical characterictic described in the utility model, be the known technology of those skilled in the art.
