Abstract
The invention discloses a radiating device of an outdoor radio frequency unit. The radiating device comprises a first die cavity and a second die cavity, wherein a cover plate is arranged between the first die cavity and the second die cavity, and the middle part of the cover plate is hollow. By using the novel device, the contact area of the outer surface of the outdoor radio frequency unit and air is increased, and the radiating efficiency is increased; meanwhile, the heat radiation between the first die cavity and the second die cavity is reduced, so that the temperature of internal modules of the first die cavity and the second die cavity is effectively reduced, and the reliability of system operation is improved.
Description
Technical field
The present invention relates to a kind of heat abstractor, refer in particular to a kind of heat abstractor that can distribute heat that outdoor radio frequency unit produces fully, fast.
Background technology
As shown in Figure 1, the radiator structure of present outdoor radio frequency unit (RRU) is made up of first die cavity 1 and second die cavity 2; Be lined with water proof ring between first die cavity 1 and second die cavity 2, and connect, and constitute a complete airtight radiator structure with bolt.On the inner surface of this structure, be fixed with heat radiation elements such as power amplifier module, radio-frequency module, numerical portion and power supply, and the screening cover with screw is arranged on power amplifier and video module, prevent that the signal between the module from disturbing.The heat that the inside components and parts of this structure are distributed is to distribute through the radiation tooth and the direct free convection of outside air of first die cavity 1 and second die cavity, 2 outer surfaces.
Because the heat that the inside components and parts of RRU are distributed is bigger, the temperature that causes this inside configuration air is than higher, and then reduction RRU operating efficiency, shortens the working life of the inner components and parts of RRU.In order to reduce the air themperature of this inside configuration; The general measure of being taked is the overall volume that increases the tooth depth of this structural outer radiation tooth or increase this structure; But so scheme will cause this equipment volume increase, weight to increase; To reduce portability of equipment, and improve the manufacturing cost of equipment.
Summary of the invention
The object of the present invention is to provide a kind ofly under the situation that does not increase RRU die cavity tooth depth and volume, distribute the heat abstractor of heat that outdoor radio frequency unit produces fully, fast.
For solving the problems of the technologies described above, the present invention realizes through following technical scheme: the present invention includes first die cavity and second die cavity, between first die cavity and second die cavity, comprise a cover plate, the middle part of said cover plate is a hollow out.
Because adopted above technical scheme, the present invention compared with prior art has the following advantages:, increase the area that the RRU surface contacts with air, thereby improved radiating efficiency one, because cover plate is an engraved structure; Two, because cover plate is separated first die cavity and second die cavity, reduce the thermal radiation between first die cavity and second die cavity, thereby effectively reduce the temperature of first die cavity and the second die cavity internal module, improve reliability of system operation.

Embodiment
Combine embodiment that the present invention is done further description with reference to the accompanying drawings.
A kind of outdoor radio frequency unit heat abstractor comprises first die cavity 1 and second die cavity 2, comprises a cover plate 3 between said first die cavity 1 and second die cavity 2, and the middle part of said cover plate 3 is a hollow out 303.
Said cover plate 3 comprises a plurality of ribs chamber, and its middle rib chamber 301 is arranged in outdoor radio frequency unit power amplifier module right opposite, and rib chamber 302 is arranged in the right opposite of outdoor radio frequency unit radio-frequency module.
Said cover plate 3 comprises trough 304, and said trough 304 is positioned under the said rib chamber 302.
Said cover plate 3 materials are aluminium alloy.
Said cover plate 3 is integrated one-step die casting.
Said cover plate 3 is a split-type structural, is made up of left cover 311 and right cover plate 312.
Said left cover 311 has radiation tooth 313 with right cover plate 312 surfaces.
Like Fig. 3 and shown in Figure 4, radiator of the present invention mainly comprises: first die cavity 1, cover plate 3 and second die cavity 2.
Shown in figure 15, layout has power amplifier module 101, radio-frequency module 102, digital module 103, power module 104 and lightning-protection module 105 in first die cavity 1; Shown in figure 16, layout has power amplifier module 201, radio-frequency module 202, digital module 203 and filter 204 in second die cavity 2; Wherein power amplifier module and radio-frequency module need screening cover, prevent that the signal of part disturbs separately.
When cover plate 3 was integrated, shown in figure 11, whole cover plate 3 was one-step die castings.When cover plate 3 was the non-integral structure, like Fig. 7 and shown in Figure 12, cover plate 3 was to be made up of left cover 311 and right cover plate 312; Left cover 311 is gone up with radiation tooth 313 with right cover plate 312 surfaces, can increase the contact area of this heat abstractor and air; When left cover 311 and right cover plate 312 are assembled into cover plate 3, need be lined with sealing ring 309 around its trough 304, guarantee the excellent sealing property of cover plate 3.
