Abstract
The utility model relates to an ASIC (application specific integrated circuit) board cooling structure which comprises an ASIC protecting box bottom board. An ASIC protecting box cover board is arranged on the ASIC protecting box bottom board, a cooling fan is arranged inside the ASIC protecting box cover board, the ASIC protecting box cover board is provided with air vents corresponding to the cooling fan, an included angle is formed between the cooling fan and the ASIC protecting box cover board, and an air flow passage forming board is arranged inside the ASIC protecting box cover board and is tightly connected with the cooling fan so that intervals are avoided. By the aid of the structure, air flow cannot circulate on the surface of the ASIC board, pressure drop of air flow is reduced, air flow backflow can be avoided, the cooling fan is more convenient to replace, and the temperature of the cooling fan is decreased so that the service life of the cooling fan can be prolonged.
Description
Technical field
The utility model relates to the cooling structure in a kind of circuit industry, especially relates to a kind of ASIC plate cooling structure.
Background technology
At present; In the temperature range of frequency converter operate as normal; There is the too high problem of temperature in ASIC plate 13 as shown in Figure 1, has increased cooling fan 12 afterwards and has cooled off ASIC plate 13, is characterized in that cooling fan 12 promotes the surface that fresh air blows to ASIC plate 13; Key is needed cooling-part 11 (capacitor, transformer etc.) cooling; The air intake passage 1,2 that fresh air forms from the narrow slit between frequency converter cover plate of outer casing 7 and the ASIC protection lid plate 9, air-flow can produce huge pressure drop; Through air-out passage 3,4 air is discharged; Cooling fan 12 is installed on the inner surface of ASIC protection lid plate 9 through support column; Cooling fan 12 separates with protection lid plate 9, and gapped formation return air channel 5,6 has the part air to reflux through this return air channel 5,6; Thereby the too high quality problems that cause of circuit board temperature.
The utility model content
The utility model technical problem to be solved provides the pressure drop of a kind of reduction air-flow, the ASIC plate cooling structure of air circulation phenomenon can not occur.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of ASIC plate cooling structure; Comprise ASIC protection box plate; On ASIC protection box plate, be provided with ASIC protection lid plate; Be provided with cooling fan in ASIC protection lid plate inside, offer ventilating opening on the ASIC protection lid plate corresponding, between described cooling fan and the ASIC protection lid plate angle is arranged with cooling fan.
Further in order to reach better radiating effect, the angle of described angle is 10 °.
Further in order to reduce the pressure drop of air-flow, described ASIC protection lid plate inside is provided with gas channel and forms plate, and said gas channel forms plate and ASIC protection lid plate forms a new air intake passage; Said cooling fan is close to and is installed on gas channel and forms the opposite side of plate with respect to said new air intake passage, and very close to each other between the two.
The beneficial effect of the utility model is: adopted after the said structure, air-flow can not reduce the pressure drop of air-flow in the circulation of ASIC plate surface; The airflow reflux phenomenon can not appear; The replacing cooling fan is convenient, and the self-temperature of cooling fan reduced, and can prolong its useful life.

Embodiment
A kind of as shown in Figures 2 and 3 ASIC plate cooling structure; Comprise ASIC protection box plate 10; On ASIC protection box plate 10, be provided with ASIC protection lid plate 9; Be provided with cooling fan 12 in ASIC protection lid plate 9 inside, protect on the lid plate 9 with cooling fan 12 corresponding ASIC to offer ventilating opening 8, between described cooling fan 12 and the ASIC protection lid plate 9 angle is arranged; The angle of described angle is 10 °; Described ASIC protection lid plate 9 inside are provided with gas channel and form plate 14, and said gas channel forms plate 14 and forms a new air intake passage 15 with ASIC protection lid plate 9; Said cooling fan 12 is close to and is installed on gas channel and forms the opposite side of plate 14 with respect to said new air intake passage 15, and very close to each other between cooling fan 12 and the gas channel formation plate 14.
An angle has been adjusted in the position of cooling fan 12, for example 10 °; Air intake passage 1,2 is set to the slit between frequency converter cover plate of outer casing 7 and the ASIC protection lid plate 9, and new air intake passage 15 forms plate 14 by gas channel and forms with ASIC protection lid plate 9; Through this structure, air-flow can not circulate on ASIC plate 13 surfaces, but blows over from the key components from the ASIC plate 13 endlessly; Not so much the stopping before of ventilating opening 8 of cooling fan 12, possible interior circulation has been prevented from.
It is emphasized that above is the preferable enforcement row of the utility model, and every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
