Description

A kind of AMC device

Technical field

The utility model relates to AMC (Advanced Mezzanine Card, advanced mezzanine card) device field, particularly a kind of AMC device that has heat sinking function.

Background technology

ATCA (Advance Te1ecom Computer Architecture, advanced telecom computer architecture) standard is a whole set of physical size and an electric and electronic standard of computer-oriented and communication field, be used to make up modular, high reliability, high performance large-scale communication or computer system.It comprises cabinet, front card, back card/back board, backboard, the definition of power module size, performance, interconnection circuit.The AMC standard is the standard that is used for the subcard on the ATCA front card, and it has defined the size of subcard, panel, parts such as connector.Because the application of AMC is increasingly extensive, has worked out again and used the AMC subcard to do the MicroTCA standard of veneer.MicroTCA can simply think the low-cost version of ATCA, and it uses the AMC subcard to make veneer, and definition has the structure of the cover machine frame of oneself, electric and electronic standard.The structure of AMC subcard connects simply lucid and lively, and as shown in Figure 1, the AMC subcard is made up of with PCB (Printed circuit board, printed circuit board (PCB)) 102 front panel 101.Golden finger 103 is arranged on the PCB, can with the connector on the ATCA veneer, perhaps the backboard on the MicroTCA machine frame is connected.There is the difference of the division of labor in the two sides of PCB, and one side is used for arranging devices, is called component side; Another side needs scolding tin when welding, be called face of weld.The side that PCB is last and front panel is close is called the panel side, and a side close with connector is called the connector side.

The heat dissipation design of ATCA cabinet only provides enough air quantity on system-level at present, by upstream and/or the downstream operation of several groups large-scale fans at veneer, the heat that produces on the veneer is shed.As shown in Figure 2, be radiator structure figure in the existing machine frame, the fan group among the figure provides radiating airflow for all veneers in the whole machine frame.Because fan is in service that vortex Swir1 effect and wheel hub Hub effect are arranged, and himself flow resistance of different veneers is also inequality, therefore, is difficult to guarantee that the veneer that needs dispel the heat can access enough radiating airflows.Actual conditions are: thermal value maximum, the veneer that needs most heat radiation often device density height, flow resistance are big, and getable air quantity is few more.For the AMC subcard, lost the heat-dissipating space of PCB thickness correspondence as the subcard form, and the device density on the AMC subcard is very high.As shown in Figure 3, be a kind of application scenarios synoptic diagram of AMC subcard, AMC standard code AMC subcard 301 maximum on ATCA support plate 302 can reach four polyphones to be used, and in this case, the heat dissipation environment of AMC subcard is very abominable, remains to be improved.

Common some are improved as are used some choked flow devices at cabinet guide rail place, change the distribution of air-flow in the machine frame, using staggered fan layout or less fan group to obtain the groove interdigit distributes than uniform airflow, these can improve existing heat dissipating state to a certain extent, but, these measures have weakened configuration flexibility, have reduced the universality of machine frame interoperability.These measures are only applicable to the integral body to the heat radiation situation in the whole cabinet of macroscopic view and improve, if be used to improve some concrete grooves position, not to pay too many cost, cause power consumption, noise is excessive, obtain by the sacrifice to the adjacent grooves position, the heat dissipation that therefore lacks a kind of localization, point type as a supplement.

Summary of the invention

Based on above-mentioned purpose, the technical solution adopted in the utility model is as follows:

A kind of AMC device, comprise front panel, PCB, also comprise at least one new wind fan, baffle plate, described new wind fan is arranged on the component side of PCB, one air inlet is set on the described front panel, described baffle plate is connected with described front panel, forms an air intake passage between the component side of described baffle plate and PCB, the air inlet.

Further, described baffle plate comprises plate body and support zone, and described plate body is positioned at new wind fan top, and described support zone links to each other with PCB; Also comprise old wind fan, be arranged on the PCB component side that described PCB is provided with an exhaust outlet, described old wind fan links to each other with described exhaust outlet; Described new wind fan and described old wind fan are centrifugal fan.

Further, described baffle plate is edge-on on the PCB component side, and an end is connected with fan, and the other end is connected with front panel; Also comprise old wind fan, be arranged on the upper end of PCB component side connector side; Described new wind fan and described old wind fan are wheel streaming fan.

Compared with prior art, adopt AMC device of the present utility model, can realize on the AMC device, to use high-power high performance device, improve the integrated level of equipment the configuration of dispelling the heat flexibly of AMC device; On the other hand, can reduce the temperature on the device, improve device reliability.
