Description
Technical field
The utility model relates to a kind of circulating electron radiator, belongs to technical field of electronic equipment.
Background technology
At present,, be to improve the performance of electronic product along with the fast development of electronics technology, also increasingly high to the requirement of the radiator that makes electronic element radiating that is provided with in the various electronic products.Can know that according to hot transfer principle heat transmission mainly contains three kinds of modes, i.e. conduction, radiation, convection current; Heat conducting formula is: Q=K*A* Δ T/ Δ L, and wherein, the K coefficient of heat conduction, A are heat transfer area, Δ T/ Δ L is the temperature difference in the unit distance; Thermal-radiating formula is: Q=H*A* Δ T, and wherein, H is a coefficient of heat convection value, and A is the effective area of convection current, and Δ T is the temperature difference; The formula of thermal convection is: Q=E*S*F* Δ (Ta-Tb), and wherein, E is the heat emissivity coefficient of surface area, S is a surface area.Hence one can see that, and enlarging area of dissipation is the effective way in the various heat transfer types, and in addition, good air channel is beneficial between the radiation tooth of radiator distinguished and admirable unimpeded mistake to carry out heat exchange.
But, through increasing radiator shutter area of dissipation is increased, be prone to cause the volume and weight of radiator to increase, and then need make the corresponding increase of power, thereby the use of Section Bar Heat Sinks is restricted, can't satisfy demand in many ways; In addition, increase area of dissipation and passage if maintenance volume and weight are constant, then processing technology is complicated; Especially strict more to the requirement of extrusion equipment; Correspondingly need make mould again, increase die cost, thereby significantly increase equipment drops into and energy resource consumption, and it is low to go out the material rate of finished products.To sum up, high Financial cost raising radiator performance but has difficulties to the assurance of section bar rate of finished products.
The utility model content
The purpose of the utility model is to the problems referred to above, and a kind of circulating electron radiator is provided, and reduces the mould loss; Reduction equipment drops into, and economical with materials effectively increases area of dissipation; Provide enough air channels to conduct heat simultaneously, realize the easy processing in high-density radiator and air channel thereof, and improve rate of finished products.
The technical scheme that the utility model is dealt with problems is: a kind of circulating electron radiator is provided, comprises heat-radiating substrate and a plurality of annular radiator, wherein, said a plurality of annular radiator parallel interval are arranged on the top of said heat-radiating substrate; The surface of said heat-radiating substrate is provided with groove, and the bottom of said annular radiator is provided with the riveted joint tooth, the fixed connection that matches with said groove of said riveted joint tooth; The surface of said annular radiator is provided with a plurality of radiation tooths.
Further, the distance between said radiation tooth is in 4 millimeters.
The utility model circulating electron radiator; Heat-radiating substrate and annular radiator are passed through riveted joint tooth riveted and fixed; Reduce the mould loss, reduction equipment drops into, economical with materials; And make each radiation tooth that independently air channel arranged, solved high-density radiator and air channel processing difficulties thereof, problem that rate of finished products is low; Space on the annular radiator between each parts provides enough heat transfer air channels, can conduct heat efficiently, when making its area of dissipation reach maximum, also makes radiating efficiency reach the highest.
Compared with prior art, the beneficial effect of the utility model is:
1, the utility model novel structure is reasonable in design, and preparation technology's flow process is simple, and is convenient and swift, and practices thrift the mass energy material, is beneficial to reduce the mould loss, and reduction equipment drops into, and simultaneously, fully guarantees the high finished product rate of section bar;
2, the innovation structure of the utility model significantly improves the heat transfer heat dispersion, simultaneously, significantly reduces Financial cost, increases economic efficiency, and is suitable in various relevant electronic devices and components that need the heat radiation setting and products thereof, using.
