Abstract
A kind of IP protects subrack, and comprise base (1), multiple plug-in unit (2) and the multiple outlet boxes (3) corresponding to plug-in unit (2), each plug-in unit (2) is plugged on base (1); Fixed by screw between plug-in unit (2) and outlet box (3), intermediate cryptographic seal.The utility model takes plug-in unit independently box structure, and the heating element on plug-in unit is directly connected in insert sidewall by heat-conducting block, and insert wall has fin, can the heat-sinking capability of stiffening device.Subrack structure is novel, can improve the heat-sinking capability of subrack under the degree of protection condition ensureing subrack.
Description
Technical field
The utility model relates to subrack structure field.
Background technology
Along with the employing of the control mode such as digital transformer substation, distributed AC servo system, occur requiring that subrack is installed in cabinet out of doors, the user demand such as installation on the spot.The IP degree of protection, heat dispersion, weather resistance, capability of electromagnetic shielding etc. of above-mentioned occupation mode to subrack are had higher requirement, and need in these cases to use high-protection level subrack.
Traditional subrack is dispelled the heat by free convection or forced convertion mode, but high protection subrack is generally airtight, and therefore subrack inside is easy to gather heat and causes interior environment temperature to raise, and has a strong impact on the useful life of device.
Utility model content
The high-protection level subrack of the utility model exploitation in a sealed meter environment, can realize the connection of each plug-in unit heating element and sidewall, at utmost strengthens the heat dissipation problem of plug-in unit heating element.
This high-protection level subrack have employed following technical scheme:
A kind of IP protects subrack, comprises base 1, multiple plug-in unit 2 and outlet box 3, it is characterized in that:
Each plug-in unit 2 is plugged on base 1; Fixed by screw between plug-in unit 2 and outlet box 3, intermediate cryptographic seal.
The utility model comprises following preferred version further:
Each plug-in unit (2) is independently box structure.
Plug-in unit is made up of drain pan 4, heat-conducting block 5, printed board 7, back-up block 8 and lid 9, heat-conducting block 5 is provided with between heating element 6 in printed board 7 and drain pan 4, and the respective regions between printed board 7 and lid 9 has back-up block 8, is coated with heat conductive silica gel between heat-conducting block 5 and heating element 6.
Drain pan 4 is provided with the fin of above-below direction.
The degree of protection of described subrack is IP54 degree of protection.
The utility model has following beneficial effect:
The utility model takes into account the convenient flexibility of plug use of the plug-in unit combining plug-in type subrack and the height of boxlike casing protects and good heat dissipation characteristics, uses under needing again the flexible adverse circumstances plugged and use when being specially adapted to need high protection.
The utility model at utmost can solve the heat dissipation problem of the heating element in airtight subrack inside in natural heat dissipation mode, the mode sealed by standalone insert is solved both needs plug-in unit to plug, and has and needs the situation that entirety has stronger heat-sinking capability.
Shown by the Experimental comparison results of the subrack with integral sealed, this frame mode can reduce the temperature on heating element.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of subrack;
Fig. 2 is the decomposing schematic representation of plug-in unit;
Fig. 3 is the profile of plug-in unit.
Wherein, 1 is base, and 2 is plug-in unit, and 3 is outlet box, and 4 is drain pan, and 5 is heat-conducting block, and 6 is heating element, and 7 is printed board, and 8 is back-up block, and 9 is lid.
Embodiment
Be described in further detail below in conjunction with the technical scheme of Figure of description to the application.Because high-protection level subrack needs good sealing property, do not have air to flow inside and outside subrack, the heat produced from printed board plug-in unit is difficult to directly discharge subrack outside by air.In order to the flexibility of device is considered, plug-in unit also must support plug, and the connection being therefore difficult to fix between plug-in unit and subrack wall is to strengthen the conduction of heat.
Be illustrated in figure 1 the overall structure schematic diagram of IP54 grade of the present utility model protection subrack.IP degree of protection subrack comprises base 1, multiple plug-in unit 2 and outlet box 3, and each plug-in unit 2 is plugged on base 1; Plug-in unit 2 and outlet box 3, to be fixed by screw between base 1 and plug-in unit 2, intermediate cryptographic seal, ensure the sealing of whole casing.Plug-in unit 2 and outlet box 3 according to different demands, can also be made into different in width.
Fig. 2 is the structure composition explosive view of plug-in unit 2.Guide tracked installation due to common printed board is difficult to meet heat-conducting block 5 and the connection between heating element 6 and drain pan 4, and therefore scheme have employed installing perpendicular to direction, plate face along printed board 7.
Fig. 3 is the cutaway view of plug-in unit 2, as seen from the figure, is supported by the back-up block 8 at the back side, makes heating element 6, compact siro spinning technology between heat-conducting block 5 and drain pan 4.Heating element 6, be coated with heat-conducting silicone grease or heat-conducting glue between heat-conducting block 5 and drain pan 4, to reduce the thermal resistance between them.Drain pan 4 there is fin, the cooling surface area of drain pan 4 can be increased, make the heat uploaded to by heating element 6 spread in surrounding air as early as possible, finally reach the object of the surface temperature reducing heating element 6.
Claims (5)
