Deficiency, if fixed structure can make entire LED power bear for example, the one, equipment is in a kind of environment of shaking
Vibration eventually leads to power supply damage；Two, due to being locked using fixed structure, it is difficult to be dismantled, it is necessary to revolve
Lower LED power could be dismantled by turning lower screw, and working efficiency is very low；Three, the structure of this fixation causes among power panel
Electronic component be it is fixed, air-flow mobility existing for centre is full, and heat dissipation performance is caused to be deteriorated.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of heat dissipation cast LED powers, using a kind of hanging peace
The mode of dress can effectively solve the problem that many deficiencies in the prior art.
The utility model is achieved through the following technical solutions: a kind of heat dissipation cast LED power, including power drives
Mainboard and the more than one electronic component being set on power drives mainboard, the bottom of the power drives mainboard are provided with
One block of heat sink, the assembly cavity that there is a upper and lower side to be open for the centre of heat sink, the power drives mainboard tip upside down on dress
With in chamber, the electronic component on power drives mainboard is inserted into assembly cavity；
The upper surface of the assembly cavity is provided with a step surface, and power drives mainboard buckles into step surface, the upper end
Face is locked by more than one first lock screw and step surface, and the two sides of the heat sink offer more than one flat
Jack, is incorporated with a cooling fin in flat jack, and for the cooling fin in flat, one end of cooling fin is inserted in flat jack
In, inserting end is respectively provided with a sealing piston, and sealing piston seals entire flat jack, the bottom of the flat jack and assembly
The venthole communicated is opened up between chamber.
One or more cooling fin is in flat as a preferred technical solution, is elastic metallic material.
The other end of one or more cooling fin fixation as a preferred technical solution, is inserted among a pedestal, and two
Pedestal supports monolith heat sink, and heat sink is vacantly set between two pedestals.
The outboard end of the pedestal is provided with an extension as a preferred technical solution, is provided on extension
More than one second lock screw, pedestal are installed on shell by the locking of more than one second lock screw.
The beneficial effects of the utility model are: the utility model is used using a kind of hanging radiating mode using equipment
Vibration environment, may make each cooling fin to swing with respect to heat sink, realize heat dissipation, and there is extraordinary anti-seismic performance, and have
The function of standby fast assembling-disassembling, heat sink and power drives mainboard under fast demountable, without unclamping screw.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As depicted in figs. 1 and 2, it including power drives mainboard 5 and is set to more than one on power drives mainboard 5
Electronic component, the bottom of power drives mainboard 5 are provided with one block of heat sink 11, and the centre of heat sink 11 has a upper and lower side equal
The assembly cavity 6 of opening, power drives mainboard 5 tip upside down in assembly cavity 6, and the electronic component on power drives mainboard 5 is inserted into dress
With in chamber 6；
The upper surface of assembly cavity 6 is provided with a step surface, and power drives mainboard 5 buckles into step surface, thereon end face
It is locked by more than one first lock screw and step surface, the two sides of heat sink 11 offer more than one flat jack
8, it is incorporated with a cooling fin 3 in flat jack 8, for cooling fin 3 in flat, one end of cooling fin 3 is inserted in flat jack 8
In, inserting end is respectively provided with a sealing piston 4, and sealing piston 4 seals entire flat jack 8, the bottom of flat jack 8 and assembly
The venthole communicated 7 is opened up between chamber.
Wherein, one or more cooling fin 3 is in flat, is elastic metallic material.Due to using flat
Elastic metallic, as long as therefore pull out monolith heat sink upwards, that is, can be taken off power drives mainboard, realize fast assembling-disassembling, and one
Above cooling fin can restore deformation, not influence to use its next time.
Wherein, the other end of one or more cooling fin fixation is inserted among a pedestal 2, and two pedestals 2 support whole
Block heat sink 11, heat sink 11 are vacantly set between two pedestals.The outboard end of pedestal 2 is provided with an extension 1, extension
More than one second lock screw is provided on 1, pedestal 2 is installed on outer by the locking of more than one second lock screw
On shell.Substructure height is higher than the height of heat sink, therefore heat sink is in vacant state always, therefore when external environment is vibrated
When, so that monolith heat sink shakes, each cooling fin is shaken, so that cooling fin makees expanding-contracting action in flat jack, is inserted flat
Air in hole enters in assembly cavity from venthole export, radiates to the power drives mainboard buckled into assembly cavity.
The beneficial effects of the utility model are: the utility model is used using a kind of hanging radiating mode using equipment
Vibration environment, may make each cooling fin to swing with respect to heat sink, realize heat dissipation, and there is extraordinary anti-seismic performance, and have
The function of standby fast assembling-disassembling, heat sink and power drives mainboard under fast demountable, without unclamping screw.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
