Abstract
Provided is a graphite radiator, comprising a baseplate. The baseplate is provided with a plurality of cooling fins, and surfaces of the cooling fins are in a wavy shape or a serrated shape. A groove is disposed on the baseplate. One or more grooves are used to coordinately place a heat release body. A shape of the groove is matched with a shape of a heating element. The baseplate, the cooling fins, and the grooves are made of expanded graphite and a curing agent, and the three are compressed to form integrally. The graphite radiator increases an effective heat radiating area of a radiator, and ensures heat generated by the heating element to be conducted in the radiator rapidly and effectively. The radiator is simple in structure, convenient in operation, low in production cost, and has good heat radiation performance. The graphite radiator is compressed to form, so as to provide convenience for production. The graphite radiator can be widely used for heat radiation of electronic heating elements.
Description
Technical field
The utility model relates to a kind of radiator, particularly a kind of heat radiator of the new structure for the electronic heating body.
Background technology
Electronic devices and components (as central processing unit) in use produce a large amount of heats, and itself and system temperature are raise, and cause the Performance And Reliability of whole system to reduce, and electronic devices and components itself are also caused damage.Therefore electronic devices and components are general only effectively works in certain temperature range, can normally move for guaranteeing electronic devices and components, at electronic devices and components heat abstractor is installed usually, discharges the heat of its generation.
Traditional radiator is made by metal materials such as copper or aluminium, generally is made of the some fin on the base plate that contacts with electronic devices and components, the base plate and the fan that is installed in the fin top.After the heat that produces during the electronic devices and components operation is absorbed by base plate, by fin calorie spread is lower than to temperature in the surrounding environment of heatsink temperature again, has reached the purpose of heat radiation.
Graphite has good heat conduction, heat dispersion, and its conductive coefficient height can reach 100～1000W/m.K.Under equal area, graphite heat conducting coefficient ratio copper, aluminium are high 3～5 times, and weight is 1/8 of copper, is 1/2 of aluminium, especially meets the developing direction of electron trade---the heat radiation requirement of miniaturization, lightness.The version of present heat radiator, the efficiently radiates heat area is limited, is unfavorable for the heat radiation of electronic devices and components.The fin surface of the utility model heat radiator is wavy, increases the efficiently radiates heat area of radiator in identical space; The base plate of radiator is provided with groove, makes radiator closely contact electronic devices and components, guarantees that the heat that electronic devices and components produce is transmitted in radiator and the heat abstractor (radiator fan etc.) effectively.Table 1 has been listed parameters such as the conductive coefficient, specific heat capacity of aluminium, copper, graphite.

Summary of the invention
Technical problem to be solved in the utility model provides a kind of heat radiator, can increase the efficiently radiates heat area of radiator, guarantees that the heat that electronic devices and components produce is transmitted in radiator and the heat abstractor (radiator fan etc.) effectively.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of heat radiator, comprise base plate, and the polylith fin is installed on the described base plate, the surface of described fin is wavy or zigzag; Also be provided with groove on the described base plate.
Described groove is one or more, be used for cooperating placing radiator body, and the shape of groove matches with the shape of heater.Groove can be flat, polygon, semicircle or arc, determines concrete shape according to the heater of required heat radiation.
Described base plate, fin and groove all adopt expanded graphite and curing agent to make, and with three in one compression moulding.
The fixed carbon of expanded graphite is more than 80%, the base plate of fin, trough of belt is one one-shot forming compacting during compacting, avoid the radiator internal structure situation of layering to occur, the anisotropic advantage that still keeps graphite itself, hotly play a part heat insulationly vertically breaking, laterally have very high conductive coefficient and can transmit heat and play heat radiation.
A kind of heat radiator that the utility model provides, the surface of fin is wavy or zigzag, can increase the efficiently radiates heat area of radiator; Base plate is provided with groove, makes heater to be dispelled the heat can closely contact heat radiator, guarantees that the heat that electronic devices and components produce is transmitted in radiator and the heat abstractor effectively.
Reasonable in design of the present utility model is improved the heat dispersion of heat radiator, produces easy, easy mass production.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment
As shown in Figure 1-Figure 3, the utility model comprises base plate 1, and the regularly arranged fin of polylith 2 is installed on the described base plate 1, and the surface of described fin is wavy or zigzag; Also be provided with groove 3 on the described base plate 1.
Described base plate 1, fin 2, groove all adopt expanded graphite and curing agent to make, and with three in one compression moulding.
Embodiment 1:
As shown in Figure 2, a kind of new structure heat radiator comprises loose base plate 1, fin 2 and groove 3, also is provided with groove 3 on the described base plate 1, and groove is flat, polygon, semicircle or arc, can be close to fixing with the electronic heating body.
During use, heater is fixed in the groove 3, and the heat of its generation at first conducts to the base plate 1 of heat radiator, and the heat of base plate 1 is transmitted in the fin 2 fast, by fin 1 calorie spread is lower than to temperature in the surrounding environment of heatsink temperature again, to reach the purpose of heat radiation.
Embodiment 2:
As shown in Figure 3, a kind of new structure heat radiator comprises loose base plate 1, fin 2 and groove 3, also is provided with groove 3 on the described base plate 1, and groove is flat, polygon, semicircle or arc, can be close to fixing with heater.In the utility model two heat radiator mirror images are placed, the bottom surface that is about to the base plate 1 of two heat radiators is close together, position forms polygon, circle or an irregular groove 3 in the middle of it, heater is installed in the groove 3 then, make the surface of heater closely contact with the surface of groove 3, the heat of its generation can rapid diffusion.The radiator group that this structure is formed has increased area of dissipation effectively, and can make heater closely contact heat radiator, can guarantee powerful tubulose electronic devices and components efficiently radiates heat.
