Description

A kind of heat radiating type radome

Technical field:

The utility model relates to electronic devices field, particularly relates to a kind of heat radiating type radome.

Background technology:

General electronic equipment, as television set, computer, testing equipment etc. are all provided with numerous electronic building bricks.When electronic device works, also can distribute heat while electronic building brick generates electromagnetic waves.

Radome is made up of supporting leg and cover body, and supporting leg and cover body are for being flexibly connected, and cover body is spherical crown shape.Being mainly used in mobile phone, the fields such as GPS, is prevent electromagnetic interference (EMI), play shielding action to the element on pcb board and LCM.Electromagnetic shielding adopts low resistance conductor material, and utilize the loss in the reflection of electromagnetic wave on shielded conductor surface and the absorption at conductor and transmitting procedure and the continuation transmission of electromagnetic wave energy is hindered, play shielding action, most of incident wave can be launched by some shielding material, utilize absorbed inside and multipath reflection to lose the electromagnetic wave partly entering material, only allow the electromagnetic wave permeable material of minute quantity to continue to propagate.

Existing radome has certain radiating effect, but when on the pcb board card be connected with radome, components and parts temperature raises too fast, heat radiation will be had little time, components and parts can be caused to burn out and increase thermal radiation, heat sinking function is strong, and the components and parts simultaneously on pcb board card can damage components and parts because shaking with radome contact internal walls.

Utility model content:

In order to solve the problem, it is simple that the utility model provides a kind of structure, can realize heat radiation and electromagnetic shielding, radiation proof function, play the technical scheme of good shockproof effect simultaneously:

A kind of heat radiating type radome, mainly comprise radome, fin, radome is cuboid hollow structure, radome is provided with an end face and four sides, end face is provided with multiple louvre, four sides are respectively equipped with multiple " several " font louvre, four angles bottom radome arrange pedestal respectively, on pedestal and pcb board card, four through holes are connected, radome inside top surface also arranges heat conductive silica gel, and radome top is screwed connection fin, and fin comprises diapire and fin, fin is vertical with diapire, in groove between two fins.

As preferably, " several " font louvre on a side is corresponding with " several " the font louvre position of on opposite flank.

As preferably, the length of " several " font louvre is 0.8mm-1.2mm, and width is 0.3mm-0.6mm.

As preferably, the louvre on end face is circular, and diameter is 1-1.5mm.

As preferably, components and parts close contact on heat conductive silica gel and pcb board card.

The beneficial effects of the utility model are:

(1) the utility model arranges thermal vias at radome end face, increases a fin again, can strengthen heat dispersion, have electromagnetic shielding and radiation proof function simultaneously at radome end face.

(2) the utility model increases heat conductive silica gel in radome inside top surface, and heat conductive silica gel and chip close contact, can pass the heat on chip fast, play shockproof effect simultaneously, when pcb board card is given a shock, and can well protect IC.

Accompanying drawing illustrates:

Fig. 1 is radome stereogram of the present utility model;

Fig. 2 is heat radiating fin structure figure of the present utility model;

Fig. 3 is radome upward view of the present utility model;

Fig. 4 is the pcb board card schematic diagram be connected with radome in the utility model.

Embodiment:

For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.

As Figure 1-4, a kind of heat radiating type radome, mainly comprises radome 1, fin 2, radome 1 is in cuboid hollow structure, and radome 1 is provided with an end face 3 and four sides 4, and end face 3 is provided with multiple louvre 11, louvre 11 on end face 3 is circular, and diameter is 1-1.5mm.

Four sides 4 are respectively equipped with multiple " several " font louvre 41, the length of " several " font louvre 41 is 0.8mm-1.2mm, width is 0.3mm-0.6mm, " several " font louvre 41 on a side 4 is corresponding with " several " font louvre 41 position of on opposite flank, make air can convection current, thus take away heat faster.

Four angles bottom radome 1 arrange pedestal 5 respectively, pedestal 5 is connected with four through holes 61 on pcb board card 6, inside radome 1 end face 3, heat conductive silica gel 7 is also set, radome 1 top is screwed and connects fin 2, fin 2 comprises diapire 21 and fin 22, fin 22 is vertical with diapire 21, in groove between two fins 22, radome 1 end face itself arranges louvre, radiating effect can be played, a fin 2 is increased again at radome top, radiating effect can be strengthened, prevent electronic devices and components on pcb board card 6 from having little time heat radiation because heating up too fast, the effect of electromagnetic shielding can also be played simultaneously.

Heat conductive silica gel 7 and components and parts close contact on pcb board card 6, can pass the heat on chip fast, play shockproof effect simultaneously, when pcb board card is given a shock, and can well protect IC.

Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
