Abstract

The utility model relates to a radiating device, which comprises a seal shell, radiating liquid and air radiating pipeline. The seal shell is used for accommodating a device to be cooled; the radiating liquid is filled in the seal shell and is sufficient to submerge the device to be cooled; and the air radiating pipeline penetrates through the wall of the seal shell and the cavity in the seal shell. With the dual radiation through delicate combination of liquid radiation and air-cooling radiation, the heat absorbed by the liquid can be dispersed out through the shell and then be transmitted to the outside through the radiating pipeline, thereby achieving good radiating effect. Since the device to the cooled is cooled under the sealed condition, the utility model has a good effect of preventing dust, insects and other types of pollution. The utility model can particularly ensure the long-term normal operation of the electrical equipment and the electronic equipment.

[technical field]

The utility model relates to a kind of heat abstractor, particularly a kind of heat abstractor that is applicable to electric equipment and electronic equipment based on the liquid cools heat radiation.

[background technology]

For various electric equipments and electronic equipment, because the heat that work produces can't obtain the problem of timely and effective processing, just heat dissipation problem is one of most important reason that influences operate as normal.

Industry has proposed various heat sink conceptions, cuts both ways.

For example, dispel the heat, adopt fin coupling fan to carry out wind-cooling heat dissipating more for electronic equipment for electric equipment such as transformer adopting insulating oil.

But, there is no liquid cooling and air-cooled cooperation heat sink conception preferably at present.

[utility model content]

In view of this, be necessary to provide a kind of liquid cooling and air-cooled ingenious cooperation and radiating effect is splendid, and be applicable to the heat abstractor of electric equipment and electronic equipment.

To achieve the above object, the utility model adopts following technical scheme:

A kind of heat abstractor comprises: seal casinghousing, the ccontaining device that needs heat radiation; Radiator liquid is encapsulated in the sealing housing and is enough to cover the device that this need dispel the heat; And the air hot channel, run through the shell wall of sealing housing and pass cavity in the sealing housing.

Preferably, this air hot channel comprises the shell wall that runs through the sealing housing and passes the tracheae of the cavity of sealing housing.

Preferably, this air hot channel further comprises the air chamber that is arranged at sealing housing middle part, and the cross section of this air chamber is greater than this tracheae, and this tracheae runs through the shell wall of sealing housing and passes the cavity of sealing housing and be connected with this air chamber.

Preferably, the outside wall surface of the air chamber of this air hot channel and tracheae are positioned to extend on the outside wall surface at position of sealing housing and are provided with a plurality of fin.

Preferably, this tracheae comprises two at least, runs through the shell wall of sealing housing respectively and passes the cavity of sealing housing and be connected with this air chamber.

Preferably, this annulus trachealis is around the cavity that passes the sealing housing.

Preferably, fan is housed to this air hot channel coupling.

Preferably, this air hot channel is covered by this radiator liquid.

Preferably, this radiator liquid is not filled up the cavity of sealing housing, and the outside wall surface of sealing housing is provided with a plurality of fin.

Preferably, this device that need dispel the heat is electric equipment or electronic equipment, and the electric wire of this electric equipment or electronic equipment leads to the sealing outside, and this radiator liquid is an iknsulating liquid.

The utility model utilizes the dual heat radiation of liquid heat radiation and the ingenious cooperation of wind-cooling heat dissipating, and the heat that liquid absorbed not only looses outward by housing, and rejects heat to the outside by hot channel, and radiating effect is fabulous.

The utility model dispels the heat under the condition of sealing to the device of need heat radiation, prevents that the effect of dust, insect and other pollution is splendid, particularly for electric equipment and electronic equipment, has guaranteed the realization of long-time operate as normal.

[embodiment]

Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by embodiment of the present utility model is described in detail.

As shown in Figure 1, the utility model is applied to high-frequency plasma electrodeless discharge lamp and low frequency electrodeless lamp, because bulb inside does not have filament, therefore the life-span of light fixture is depended on the electronic circuit and the bulb manufacturing technology of lamp, that is to say, the heat radiation of electronic circuit is very big to the lamp life influence, and the advantage of heat radiation of the present utility model has obtained splendid embodiment.And, the high-frequency plasma electrodeless discharge lamp extensively should be in industry, commerce and public illumination, as market, factory building, venue, station, harbour, airport, subway station, highway, town road, bridge and tunnel etc., the comparatively abominable place of particularly most of environment, the utility model dispels the heat under the condition of sealing to circuit, prevents that the effect of dust, insect and other pollution is splendid.

Heat abstractor of the present utility model comprises seal casinghousing 1, air hot channel and is encapsulated in the seal casinghousing 1 and is enough to cover the device (circuit board 5) that needs heat radiation and the radiator liquid 6 of air hot channel;
