Description
Technical field
A kind of large power supply is the utility model is related to, it is more particularly to a kind of high-power without air-cooled high-reliability electrical source.
Background technology
Existing large power supply is to cool down or irrigate glue heat conduction by blower fan to realize the purpose that device radiates, and is originally set
Meter scheme power supply heat sinking does not need blower fan and glue embedding, by natural cooling, realizes power output.Deposited using blower fan cooling
The fan noise and life-span the problem of, while the problems such as the operating of blower fan can bring electromagnetic interference.Existed using the embedding of silica gel water
The low thermal conductivity of glue, heat transfer difference and bring heater members radiating it is unbalanced.Simultaneously because embedding filling glue and first device
Between part the reason for thermal coefficient of expansion, embedding filling glue expands larger at high operating temperatures, has extruding to component, in low temperature shape
Expand smaller under state, have stretching to component, such telescopic variation can cause transformation magnetic core constant power device damage, reduce production
The reliability of product.
The content of the invention
The purpose of this utility model is the defects of overcoming prior art to exist, there is provided a kind of high-power more than 500W power supplys
On the premise of without using blower fan and embedding filling heat conduction glue each power device temperature rise on power panel can be made to reach expected
Requirement, simultaneously because do not use glue and blower fan, improve power supply reliability it is high-power without air-cooled high-reliability electrical source.
Realizing the technical scheme of the utility model purpose is：It is a kind of high-power without air-cooled high-reliability electrical source, have by upper lid
With the shell of drain pan composition；Power supply pcb board is installed in the shell；The drain pan is in " Contraband " font of 90 ° of rotate counterclockwise,
The side of drain pan there is lateral arrangement and the integrally formed comb teeth-shaped groups of fins by equidistantly distributed into big radiator；Institute
The unified layout of power device on power supply pcb board is stated in the side by big radiator, and PFC boost inductance on power supply pcb board,
Resonant inductance and main power transformer are in close contact by lid on upper and lower two pieces of heat conductive pads and power supply and drain pan.
Upper lid is L-shaped described in above-mentioned technical proposal, offers corresponding mounting hole on upper lid and bottom shell, and pass through fastening
Part connects.
Upper lid and bottom shell is 5mm described in above-mentioned technical proposal.
Heat conductive pad described in above-mentioned technical proposal is 2mm.
After adopting the above technical scheme, the utility model has following positive effect：
(1) continuous output more than the requires of the utility model 500W, -10 ° to+50 ° of operating ambient temperature, input electricity
90~264VAC of scope is pressed, each work(on power panel can be made on the premise of without using blower fan and embedding filling heat conduction glue
Rate device temperature rise reaches expected requirement, simultaneously because not using glue and blower fan, improves the reliability of power supply.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view；
Fig. 3 is stereogram of the present utility model.
Embodiment
(embodiment 1)
See Fig. 1 to Fig. 3, the utility model has the shell being made up of upper lid 1 and drain pan 2；Power supply PCB is installed in shell
Plate 3；Drain pan 2 is in " Contraband " font of 90 ° of rotate counterclockwise, and the side of drain pan 2 has lateral arrangement and integrally formed by between grade
The big radiator that comb teeth-shaped fin 4 away from distribution forms；The unified layout of power device on power supply pcb board 3 is by big radiating
The side of device, and PFC boost inductance, resonant inductance and the main power transformer on power supply pcb board 3 pass through upper and lower two pieces of thickness
Spend and be in close contact for 2mm heat conductive pad 5 with lid 1 on power supply and drain pan, upper lid 1 and drain pan 2 are 5mm.
Upper lid 1 is L-shaped, and upper lid 1 and drain pan 2 are metal material, and corresponding installation is offered on upper lid 1 and drain pan 2
Hole, and connected by fastener.
Operation principle of the present utility model is：Because the size requirement of power supply is 330*140*38mm, 1U cabinets height with
Under requirement it is stricter, width has certain allowance, therefore using the lateral arrangement of radiating element, all devices in shell
Heat is to conduct to incite to the big radiator of side by metal shell to penetrate.Therefore, when power supply pcb board 3 is laid out, all power devices
Part is unified to be laid out along close to the side of fin, to ensure that heat radiation is radiated with most short path to radiator.PFC boost inductance
With resonant inductance and main power transformer by controlling its body height, allow itself and lid on power supply 1 and drain pan to be in close contact, incite somebody to action
Heat is by thicker 5mm upper lid and bottom shell with the radially outer radiator shutter direction blade conduct radiation of shortest path.The upper thickness of lid 1
Ensure 5mm, while ensure with the outside contact area for breaing up backing to ensure the efficiency of heat transfer.Transformer and inductance and upper lid
Connected between 1 and bottom by 2mm heat conductive pad 5, inductance and transformation are improved on the premise of ensureing to eliminate the influence of vortex
The radiating efficiency of device.
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
