Description

A kind of subrack realizing front and back and radiating

Technical field

The utility model relates to industrial subrack field, in particular to a kind of subrack realizing front and back and radiating.

Background technique

Circuit board module and it is easy to maintain be industrial subrack characteristic, currently, industrial subrack be widely used in communication, In each field such as electric power, rail traffic.Since the circuit board integrated level inside subrack is higher, plate-laying is more intensive, to ventilation It radiates requirement with higher, if heat dissipation performance is bad, it will the precision for directly influencing electronic equipment, when serious Therefore the electronic component that will also directly burn on circuit board dissipates demanding subrack for heat, design a reasonable heat dissipation Air duct is vital.

Existing subrack (such as 4U subrack) is typically all to be made of outer case, external plate and integral type backboard, wherein one Body formula backboard is set to the inside on rear side of outer case, row-needle receptacle is integrated on integral type backboard, before external plate is inserted in outer case End.In order to obtain preferable heat dissipation effect, currently, being primarily present following two heat-removal modalities：The first is to increase to insert The heat dissipation hole area of case upper and lower part, makes cooling wind radiate from bottom to top；Second is the height for increasing original subrack, is made Cooling wind radiates from the front to the back.But there are following defects for existing radiating mode：

The subrack radiator structure to be radiated from bottom to top using the first, can actually be effective in only separate unit subrack Raising thermal diffusivity；But when multiple subracks being put into cabinet and superposition is placed in together up and down, it will influence whole dissipate Thermal effect, just must increase relevant radiator fan in interior of equipment cabinet at this time can effectively radiate, otherwise stack to The cabinet of topmost will assemble a large amount of heat, this certainly will influence whether the performance of electronic component；Meanwhile increasing fan not The meeting effective space of interior of equipment cabinet is only accounted for, also will increase the noise and energy consumption of cabinet.

The subrack to be radiated from the front to the back using second needs to increase the height of subrack.Since it is desired that at the bottom of subrack Portion designs air intake passage, carries out outlet air by the upper end that air duct from front to back is directed to rear portion, this causes to increase when design Insert the height of case.And after increasing the height of subrack, original standard 4U subrack can be made to become non-standard structure, therefore, it is necessary to In addition designing corresponding non-standard cabinet just can be carried out placement, while will also result in waste to the space of cabinet, be unfavorable for improving The utilization rate in space.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of subrack realizing front and back and radiating, passes through the subrack Heat dissipation effect can be improved.

The utility model is realized in this way：A kind of subrack realizing front and back and radiating, the ventilation device include a subrack Ontology, plural block separate type backboard, and it is inserted in plate outside the plural block of subrack ontology front end；The subrack ontology Fore inside is provided with a plurality of plate guide grooves, and there are one first ventilating ducts between the adjacent two plate guide groove, often The external plate is inserted in a plate guide groove；Each separate type backboard is a pair of with each plate guide groove one It should be erected on the inside of the subrack rear body, and there are one second ventilations for correspondence between the adjacent two separate type backboard Road, first ventilating duct are connected with second ventilating duct.

Further, the subrack further includes an at least fan；After each fan is fixedly arranged on the subrack ontology End, and second ventilating duct is blowed by each fan.

Further, pass through the inner wall that a connection piece is fixed on the subrack ontology per the separate type backboard.

The utility model has the advantage of：1, the first ventilating duct and the second ventilating duct of setting be can use to realize by preceding To rear or from back to front radiate, by this radiating mode, so that not only can satisfy the heat dissipation of subrack ontology itself Demand, and can guarantee that subrack ontology carries out the thermal diffusivity of Superimposed installation in cabinet, while without the existing 4U of change The calibrated altitude of subrack；2, it when radiating requirements are larger, can also carry out forcing heat dissipation by the fan of setting.

Specific embodiment

Please emphasis referring to figs. 1 to shown in Fig. 2, the utility model is a kind of to realize the preferable implementation of subrack 100 that front and back is radiated Example, the subrack 100 includes a subrack ontology 1, plural block separate type backboard 2, and is inserted in 1 front end of subrack ontology Plate 3 outside plural block；The fore inside of the subrack ontology 1 is provided with a plurality of plate guide grooves 4 (as shown in Figure 1, inserting Be correspondingly arranged on a plurality of plate guide grooves 4 on two inner walls up and down of 1 front of case ontology), the plate guide groove 4 for realizing External plate 3 is inserted into subrack ontology 1, there are one first ventilating ducts 5 between the adjacent two plate guide groove 4, this One ventilating duct 5 is used for ventilation and heat, is inserted in a plate guide groove 4 per the external plate 3；Each separate type back Plate 2 corresponds the inside for being erected on 1 rear portion of subrack ontology (i.e. in the subrack ontology 1 with each plate guide groove 4 The inside at rear portion is vertically equipped with a separate type backboard 2 in the corresponding position per the plate guide groove 4), and described in adjacent two It is corresponded to there are one second ventilating duct 6 between separate type backboard 2, first ventilating duct 5 is connected with second ventilating duct 6 It is logical.In this way, when specifically used, so that it may which first ventilating duct 5 and the second ventilating duct 6 are realized from front to back or by rear To before radiating, by this radiating mode, so that not only can satisfy the radiating requirements of subrack ontology itself, but also can be with Guarantee that subrack ontology 1 carries out the thermal diffusivity of Superimposed installation in cabinet, while high without the standard for changing existing 4U subrack Degree.

The subrack 100 further includes an at least fan 7；Each fan 7 is fixedly arranged on the rear end of the subrack ontology 1, And second ventilating duct 6 is blowed by each fan 7.The purpose that fan 7 is arranged is：Can by fan 7 come The inside of subrack ontology 1 is carried out to force heat dissipation, to realize better heat dissipation effect.

The inner wall of the subrack ontology 1 is fixed on by a connection piece 8 per the separate type backboard 2.

The subrack 100 of the utility model when in use, can carry out external plate 3 by the plate guide groove 4 of setting Plug operation, meanwhile, the first ventilating duct 5 and the second ventilating duct 6 that can use design to carry out from front to back subrack ontology 1 Or it radiates from back to front；When needing to carry out subrack ontology 1 to force heat dissipation, then it can open fan 7 and radiate.

Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
