Simultaneously, the utility model also provides a kind of structure of regulating Volume Changes after the power supply thermal expansion, its with fastening foot rest be installed with Seal Oil every, utilize Seal Oil in the time can solving power work effectively, because the Volume Changes that the hot caused thermal expansion that device produces brings, make the power supply internal and external pressure balance, thereby improved the waterproof ability of power supply greatly.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED driving power waterproof and radiator structure, waterproof and radiator structure comprise that outer casing of power supply, O-ring seal, Seal Oil are every, insulating heat-conductive filling liquid and fastening foot rest, described fastening foot rest with Seal Oil every being installed on the outer casing of power supply, be installed with O-ring seal between fastening foot rest and the outer casing of power supply, be filled with the insulating heat-conductive filling liquid in the outer casing of power supply, have oil on the fastening foot rest every spiracle.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Be provided with the power circuit components and parts in the described outer casing of power supply, the power circuit components and parts are immersed in the insulating heat-conductive filling liquid.
Described Seal Oil is every being wholely set with O-ring seal.
Described oil separates corresponding to Seal Oil every spiracle to be established.
Described Seal Oil is every directly contacting with the insulating heat-conductive filling liquid of filling in the outer casing of power supply.
Described Seal Oil is every adopting the flexible resilient material that can stretch to make.
The beneficial effects of the utility model are: the utility model is than driving power of the prior art, and the heat dissipation problem when the utility model has solved power work has effectively reduced the temperature rise of power supply, prolongs power source life; And avoided because thermal expansion to the extruding that components and parts produce, has improved the reliability of power supply; Embedding operation when being easy to power supply production, maintenance difficult after the solution embedding, and the recyclable utilization again of filler, thus reduced cost.When the utility model can also solve power work effectively, because the Volume Changes that the hot caused thermal expansion that device produces brings, make the power supply internal and external pressure balance, thereby improved the waterproof ability of power supply greatly.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
