Wherein: 1 upper cover, 2 radiating surfaces, 3 Heat Conduction Materials, 4CPU, 5 electromagnetic radiation generation devices, 6 louvres, 7 surrounding edges.
Embodiment
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, the electromagnetic shielding for on-vehicle host described in the embodiment of the present invention is held concurrently heat abstractor, comprise and electromagnetic radiation generation device is wrapped in interior radome, described radome is provided with radiating surface identical with CPU upper surface area and can be bonded to each other.
Above-described embodiment is by the setting of radome, achieve the shielding action to electromagnetic radiation, avoid electromagnetic radiation to the interference of other equipment, and the infringement to health, be arranged on radome simultaneously CPU upper surface area identical and can be bonded to each other radiating surface, achieve the quick heat radiating of CPU, ensure that CPU operates smoothly in a reliable temperature range.
As shown in Figure 1, another embodiment of the present invention additionally provides a kind of electromagnetic shielding for on-vehicle host and to hold concurrently heat abstractor, on the basis of above-described embodiment, described radome comprises upper cover 1 and is connected to cover rim and the surrounding edge 7 bent to direction, electromagnetic radiation generation device place, described surrounding edge 7 ground connection is arranged, described radiating surface 2 be arranged on described on cover.
The object of this design is, adds surrounding edge 7 by upper cover 1, and the design of surrounding edge 7 ground connection, better wraps up electromagnetic radiation generation device 5, better avoid the Spreading and diffusion of electromagnetic radiation, shield the propagation of electromagnetic radiation simultaneously.
The electromagnetic shielding for on-vehicle host that another embodiment of the present invention provides is held concurrently heat abstractor, and the height of described radiating surface 2 is lower than the height of described other parts of upper cover 1.In this design, can adopt as shown in Figure 1 on upper cover 1, make a concave station lower than other Partial Heights, namely concave station can be used as radiating surface 2 and uses, during use, after the lower surface of concave station smears the Heat Conduction Materials such as silica gel 3, tightly fit with CPU 4 upper surface, other parts of upper cover are due to higher than concave station, certain gap can be had with other electromagnetic radiation generation device, both ensure that the shielding action to electromagnetic radiation, achieved again the efficiently radiates heat of CPU 4.
