Abstract

The utility model discloses a crib, which comprises a cabinet, a mother plate arranged on the inner back end of the cabinet, an upper and a lower slideway components connected with two side plates of the cabinet and veneers clamped in the slideway components. The utility model is characterized in that the mother plate is an integral plate without a ventilating hole, and the upper and the lower ends of the mother plate are respectively reserved with enough ventilating gap with the top and the bottom of the cabinet. The upper and the lower slideway components are shorter than the veneers clamped in the slideway components, and the back ends of the upper and the lower slideway components keep definite distance with the mother plate. Because the mother plate is an integral structure without ventilating holes and air ways are formed between the mother plate, the top and the bottom of the cabinet and the upper and the lower slideways, the crib has the advantages of excellent ventilation and large utilizable space of the mother plate, which can satisfy the wiring demand.

Description

A kind of subrack

Technical field

The utility model relates to the plant equipment of communication field, and finger is applied to a kind of subrack in the communication equipment especially.

Background technology

Because the reinforcement of communication products function and the requirement of integrated level, forced air cooling is more and more general in the communication apparatus, and the subrack of various air channel structures has just been arranged thereupon.In some cases, the system requirements subrack can cross ventilation, provides fan 03 to form the air channel by system, gives the heat radiation of the function elements such as veneer in the subrack, as shown in Figure 1.The structure of the subrack 01 of existing cross ventilation as shown in Figure 2, motherboard 02 is more lower slightly than subrack, is fixed on the subrack rear portion.The flow direction of wind is come in from the ventilation hole on the anterior veneer front panel of subrack, through board area, by motherboard, goes out from the subrack back shroud again.Therefore the subrack of this structure requires motherboard to have enough ventilation holes 04, and the motherboard perforate as shown in Figure 3.There is following shortcoming in the subrack of prior art:

1, have a lot of ventilation holes on the motherboard, weakened the intensity of motherboard, and the motherboard processing difficulties;

2, owing to a lot of ventilation holes on the motherboard, reduced the useful space of motherboard, strengthened the difficulty of motherboard upward wiring.

Technology contents

The utility model provides a kind of subrack, with the motherboard that solves the prior art subrack because of having ventilation hole so that the few technical problem of the useful space at the bottom of its processing difficulties, intensity, on the motherboard.

For addressing the above problem, the utility model provides following technical scheme:

A kind of subrack, comprise cabinet, be located at rear end in this cabinet motherboard, be connected in the up and down slideway assembly of described cabinet biside plate and be stuck in veneer in the slide assemblies, wherein, described motherboard is not for having the integral plate of ventilation hole, up and down two ends are respectively and leave enough ventilation gaps between the top of casing and the bottom for it, described up and down two slide assemblies be shorter in length than the length that is stuck in veneer wherein, the rear end and the motherboard of described up and down slideway assembly maintain a certain distance.

The bottom that the top of described cabinet is provided with upper cover plate or cabinet is provided with lower cover;

The rear portion of described cabinet is provided with bonnet.

Motherboard of the present utility model is the whole blocks structure, and ventilation hole is not set on it, forms the air channel between motherboard and cabinet top, bottom and the up and down slideway, makes this subrack well-ventilated; The available space of motherboard is strengthened, and can satisfy the cabling requirement; In addition, this subrack processing is simple, good manufacturability, and cost is lower.

Embodiment

Fig. 4, shown in Figure 5 is a preferred embodiment of the present utility model.A kind of shielding subrack of cross ventilation is by left side plate 3, sliding way assembly 4, glide path assembly 5, motherboard mounting bar 9, motherboard 2, veneer 6,

cover plate

7,10, back shroud 8 are formed up and down.Wherein left side plate, not perforates of cover plate up and down have ventilation hole on the back shroud, and the up and down slideway assembly does not have ventilation hole yet, and up and down slideway assembly and motherboard mounting bar all are fixed on the side plate by rivet, and motherboard is connected with the motherboard mounting bar.Up and down two ends are respectively and leave enough ventilation gaps between the top of casing and the bottom for motherboard, the length of two slide assemblies is all short than veneer up and down, the rear end and the motherboard of up and down slideway assembly maintain a certain distance, between slide assemblies and motherboard mounting bar, leave enough gaps like this, to form the air channel.

After subrack was installed motherboard and veneer, during the system fan exhausting, the air channel in the subrack as shown in Figure 5.Cold wind enters the veneer zone from the ventilation hole on the veneer front panel, because cover plate, slide assemblies and side plate all seal up and down, wind can only be walked back, main part by veneer, dispel the heat to the device on the veneer, arrive the motherboard rear portion again from the gap between slide assemblies and the motherboard mounting bar, go out from the ventilation hole of back shroud again.

For non-shielding subrack, cabinet can not be provided with upper cover plate 7 and back shroud 8, and cabinet also can be provided with upper cover plate and lower cover and back shroud are not set.Because the upper end face of sliding way assembly seals, and cabinet lower cover 10 also keeps, thus airflow flowing before and after can forming, to reach the purpose of veneer being carried out wind-cooling heat dissipating.

Claims

1, a kind of subrack, comprise cabinet (1), be located at rear end in this cabinet motherboard (2), be connected in the up and down slideway assembly (4,5) of described cabinet biside plate (3) and be stuck in veneer (6) in the slide assemblies, it is characterized in that, described motherboard is not for having the integral plate of ventilation hole, it leaves ventilation gap respectively and between the top of casing and the bottom in two ends up and down, the described length that is shorter in length than the veneer (6) that is stuck in wherein of two slide assemblies up and down, the rear end and the motherboard of described up and down slideway assembly maintain a certain distance.

2, subrack as claimed in claim 1 is characterized in that, the top of described cabinet (1) is provided with upper cover plate (7).
