The utility model is achieved through the following technical solutions, and the utility model comprises the sealing box body that stainless steel is made, and described box body comprises upper cover, lower cover, two side plates, front and rear panels; Under described, cover mounting circuit boards, above cover and be provided with a plurality of metal guide plumes, described metal guide plume is corresponding with the euthermic chip on circuit board, between euthermic chip and metal guide plume, is provided with heat conductive rubber layer; Two side plates are provided with the guide rail being used in conjunction with rack upper rail; The area of header board is greater than rear plate, and the end of header board is provided with the connector being connected with rack, and rear plate is provided with circuit board interface and alignment pin.
Described metal guide plume is cuboid, and cross section and the euthermic chip of metal guide plume match.Adopt a plurality of heating columns, compare in box body punching with tradition with windowing, not only processing is simple, and has avoided the destruction to box body sealing, effectively improves anti-salt fog and the effectiveness to circuit board.
Place, connection gap on described box body is provided with sealed colloid.Can improve the sealing of shielding box.
Described connector has four, lays respectively at four tops of header board, and connector is the captive screw that stainless steel is made.Adopt captive screw, can easily shielding box be connected on rack, stainless steel can play anti-salt fog effect simultaneously.
Described header board is provided with handle.Coordinate alignment pin and guide rail, be in use convenient to realize pull in rack.
Described upper cover and the moulding of metal guide plume integrally casting.Can improve heat conductivility.
The utility model has the following advantages compared to existing technology: the utility model is by being used the heating column being connected with upper cover to dispel the heat to main euthermic chip, can be in the situation that not destroying shielding box sealing efficiently radiates heat, improved anti-salt fog and the electromagnetic radiation ability of shielding box, simple in structure easy to process.

Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As shown in Fig. 1~6, the present embodiment comprises the sealing box body 1 that stainless steel is made, and described box body 1 comprises upper cover 11, lower cover 12, two side plates 13, header board 14 and rear plates 15; Mounting circuit boards 2 on described lower cover 12, upper cover 11 is provided with a plurality of metal guide plumes 3, and described metal guide plume 3 is corresponding with the euthermic chip 21 on circuit board 2, between euthermic chip 21 and metal guide plume 3, is provided with heat conductive rubber layer 4; Two side plates 13 are provided with the guide rail 5 being used in conjunction with rack upper rail; The area of header board 14 is greater than rear plate 15, and the end of header board 14 is provided with the connector being connected with rack, and rear plate 15 is provided with circuit board interface 7 and alignment pin 8.Header board 14 is provided with handle 9.Coordinate alignment pin 8 and guide rail 5, be in use convenient to realize pull in rack.
The metal guide plume 3 of the present embodiment is cuboid, and the cross section of metal guide plume 3 and euthermic chip 21 match.Adopt a plurality of heating columns, compare in box body 1 punching with tradition with windowing, not only processing is simple, and has avoided the destruction to box body 1 sealing, effectively improves anti-salt fog and the effectiveness to circuit board 2.Upper cover 11 and the 3 integrally casting moulding of metal guide plume.Can improve heat conductivility.
Place, connection gap on box body 1 is provided with sealed colloid.Box body 1 all adopts stainless steel manufacture, and the sealing of place, connection gap around use sealed colloid, further improves sealing and the anti-salt fog ability of shielding box.
The connector of the present embodiment has four, lays respectively at four tops of header board 14, and connector is the captive screw 6 that stainless steel is made.The area of header board 14 is greater than rear plate 15, is convenient on header board 14, adopt captive screw 6, easily shielding box is connected on rack, and stainless steel can play anti-salt fog effect simultaneously.
During the present embodiment work, the heat that euthermic chip 21 produces, dissipates from upper cover 11 by metal guide plume 3.Between metal guide plume 3 and euthermic chip 21, also place one deck heat conductive rubber layer 4, the good conduction of the heat of euthermic chip 21 can also have been played to cushioning effect to metal guide plume 3 time, effectively protected the damage of 3 pairs of euthermic chips 21 of metal guide plume.
