Abstract

The utility model relates to a curved fin type radiator device, which comprises a radiator main body (1) with fins and a fan (2). The utility model is characterized in that the radiator main body (1) forms a post shape, a post-shaped core (11) is arranged at the center of the radiator main body, and fins (12) are distributed in a dispersive way in radial direction along the central post-shaped core. A contacting part between the utility model and an electronic component has heavier weight, high heat transfer efficiency and sufficient heat capacity, and heat radiating fins which are especially designed and manufactured are ranged in a dispersive shape along the centre. The utility model has the advantages of low wind resistance, large heat radiating area and high heat exchanging efficiency. The heat of the electronic component is easily absorbed, and is quickly emitted to surrounding air to achieve the purpose of high heat radiating efficiency.

Description

Crooked finned radiator device

Technical field

The utility model belongs to a kind of heat sink arrangement of electronic devices and components, belongs to the high efficiency and heat radiation apparatus of integrated circuit especially.

Prior art

Existing heat-radiating device of electric component, comprise a traditional aluminium extruded formula radiator that contacts with electronic devices and components, the fin that several strips that its end face has extruding to form are arranged side by side, the space around the heat that utilizes fin that the electronic devices and components conduction is come is dispersed into is gone.For the bigger electronic devices and components of caloric value, need set up a radiator fan that the air-flow that is produced is blowed to fin at the end face of fin, radiator fan disperses the heat energy that electronic devices and components conduct to fin, so that electronic devices and components are effectively dispelled the heat.

The radiating fin of tradition aluminium extruded type radiator is the square formation shape mostly to be arranged, and is unfavorable for air flows and easily produces big windage, thereby influence radiating effect; And radiator base plate is very thin, and thermal capacity is little, and area of dissipation is also little, influences the radiating efficiency of radiator, and its radiating effect that can reach is difficult to realistic user demand.And new electronic devices and components are constantly developing and are improving, and its speed of service is more and more faster, and the heat that is produced is also more and more, and existing heat spreader structures can't obtain desirable radiating effect.

Summary of the invention

The utility model is to propose a kind of have radiating effect ideal, heat abstractor easy to use for the above-mentioned deficiency that overcomes prior art.The contact portion quality of itself and electronic devices and components is big, heat conduction efficiency is high, have sufficient thermal capacity; And the radiating fin of particular design manufacturing is divergent shape and arranges along the center, and its windage is low, and area of dissipation is big, and the heat exchanger effectiveness height is easy in time absorb the caloric value of electronic devices and components and promptly be dispersed in the surrounding air, reaches the purpose of high efficiency and heat radiation.

The purpose of this utility model can reach by taking following technical measures:

Design, a kind of crooked finned radiator device of manufacturing comprise finned radiator body and fan; It is characterized in that: described radiator body is column, and its center is the column core; Described fin is along described center column core radially disperses distribution.

Embodiment

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.

A kind of crooked finned radiator device comprises finned radiator body 1 and fan 2; It is characterized in that: described radiator body 1 is column, and its center is a column core 11; Described fin 12 is along described center column core 11 radially disperses distribution.There is a column core at the radiator body center that wherein is column, has the big characteristics of thermal capacity, can in time absorb a large amount of heats of electronic devices and components generation and be transmitted to fin on every side; Be between the fin of radially dispersing distribution along center column core, the windage of air flows is low, and heat exchange area is big; The fan belt moving air flow that is installed in radiator body top process from the fin is discharged to heat in the ambient air rapidly and goes.

Described fin 12 is the equidirectional arrangement that radially bends, the air-flow that fan drives all can present the rotation of certain orientation, be bend alignment along center column core diameter to the fin of dispersing distribution, help to be reduced in the windage of air flow between fin, produce better heat radiating effect.

Described fin is clockwise bend alignment, and when fan airstream from bottom to top passed through radiator body, air-flow was the clockwise direction rotation, and the fin that equidirectional rotation is arranged helps air-flow to pass through more glibly.

Fin axially is provided with obvious bending 121 along the air-flow end, thereby produces useful local flow-disturbing, and helping has heat exchange more fully between air-flow and the fin.

The core of described column core 11, be provided with copper post 13, because copper material itself has the heat conduction efficiency excellent characteristics, at column core center the copper post is set, the heat that can more effectively thermal source be produced in the unit interval conducts out, conducts heat in the ambient air by fin on every side and airflow flowing in time and goes.

Claims
