Abstract
The utility model relates to an efficient intensive heat dissipation structure used for a high power radio frequency power amplifier, comprising a shielding cavity; the lateral wall of the shielding cavity is provided with a set of radiating fins; a fan just opposite to the radiating fins is arranged on one side of the radiating fins; a stream guidance cover is arranged between the fan and the shielding cavity. Through the organic combination of the fan, the radiating fins and the stream guidance cover, the efficient intensive heat dissipation structure can reach the purposes of efficient cooling and heat dissipation and has the advantages of high heat dissipation efficiency, small size, light weight, simple manufacturing, etc.
Description
Technical field
The utility model relates to high-power RF power amplifier, specifically a kind of efficient intensive radiator structure for high-power RF power amplifier.
Background technology
For powerful radio-frequency (RF) power amplification, heat radiation is its key problem always.In prior art, the radiator structure of radio-frequency (RF) power amplification exists that efficiency is low, volume is large, the problem of Heavy Weight.How under minimum size, to complete the high efficiency and heat radiation demand of power amplifier, be the target of pursuing of manufacturer always.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of efficient intensive radiator structure, and this radiator structure radiating efficiency is high, and size is little, lightweight.
According to the technical solution of the utility model: a kind of efficient intensive radiator structure, comprise shielding cavity, on the lateral wall of described shielding cavity, be furnished with one group of fin, a side of described fin is furnished with the fan over against described fin, between described fan and described shielding cavity, is provided with kuppe.
Described kuppe is enclosed in described fan and described shielding cavity around.
Described fin adopts sheffield plate.
Technique effect of the present utility model is: the utility model, by the organic assembling of fan, fin and kuppe, reaches the object of temperature with high efficiency heat radiation, has radiating efficiency high, and size is little, lightweight, manufactures the advantages such as simple.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the exploded view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
In Fig. 1, Fig. 2, comprise kuppe 1, cover plate 2, joint 3, fan 4, fin 5, shielding cavity 6, copper billet 7, copper billet groove 8 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of efficient intensive radiator structure for high-power RF power amplifier, comprises shielding cavity 6, and shielding cavity 6 can more stably be worked power amplifier, forms solid containment vessel simultaneously.On shielding cavity 6, be provided with copper billet groove 8, be inlaid with copper billet 7 in copper billet groove 8, shielding cavity 6 tops are fixed with cover plate 2, and a side of shielding cavity 6 is furnished with joint 3.
On the lateral wall of shielding cavity 6, be furnished with one group of fin 5, fin 5 adopts sheffield plate, is welded in the aluminum base of power amplifier.The size of fin 5 and density is critically design after the impact that considers blast and wind speed.
One side of fin 5 is furnished with the fan 4 over against fin 5, between fan 4 and shielding cavity 6, is provided with kuppe 1.Kuppe 1 is enclosed in fan 4 and shielding cavity 6 around.Kuppe 1 has ensured that the wind of fan 4 is utilized by fin 5 the most efficiently to greatest extent.
The utility model, by the organic assembling of fan 4, fin 5 and kuppe 1, can form thermal diffusion to greatest extent in minimum heat radiation size, reaches the object of temperature with high efficiency heat radiation.The utlity model has radiating efficiency high, size is little, lightweight, manufactures the obvious advantages such as simple.
