Description
Technical field
This utility model belongs to piezoelectric ceramics applied technical field, and in particular to it is closed that a kind of utilization piezoelectric fan radiates
Cabinet.
Background technology
Piezoceramic material has unique piezoelectric effect, mechanical energy can be changed into electric energy, it is also possible to convert electrical energy into
Into mechanical energy.Using the inverse piezoelectric effect of piezoelectric ceramics, apply alternating voltage on piezoelectric ceramics, piezoceramic material can extend
Or shorten, this characteristic derives many applications, such as Piezoelectric Ceramic Fan.
Some electronic equipments current are needed for " three prevent ", by electronic integrated circuit plate in closed case, internal
Heat is radiated by cabinet side board radiator, natural radiation.Due to limited space, it is impossible to install common electromagnetic fan, closed
Temperature in chassis is high, it was found that electronic device often raises 10 DEG C, system reliability reduces by 50%, has a strong impact on the steady of electronic equipment
Qualitative, reliability.
Utility model content
Goal of the invention：For the deficiencies in the prior art, this utility model provides a kind of using piezoelectric fan radiating
Closed case, can effectively reduce side board radiator temperature, and then reduce internal integrated circuit chip temperature, improve whole machine work
The stability of operation, reliability.
Technical scheme：For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of closed case of utilization piezoelectric fan radiating, including case box, cabinet side board, piezoelectric ceramics combination wind
Fan, piezoelectric fan protective cover；Cabinet side board is set on the case box, radiating fin is set in cabinet side board outer upper, under
Piezoelectric ceramics combination fan is installed in portion, in piezoelectric ceramics combination fan peripheral hardware piezoelectric fan protective cover.
The case box is using heat conduction is conducive to and the casing made of the metal with some strength.
More than 2 pieces cabinet side boards are installed on the case box, and piezoelectric ceramics combination is all provided with each cabinet side board
Fan.
The piezoelectric ceramics combination fan is composed in parallel by multiple Piezoelectric Ceramic Fan blades, and piezoelectric fan blade is by two
Piece piezoelectric ceramics and target composition, back and forth deflect under the driving of electric field, play fan effect.
The closed case of the new utilization piezoelectric fan radiating of this practicality, in cabinet side board top milling radiating fin, under
Piezoelectric ceramics combination fan blade is installed in portion, and when closed case works, internal integrated circuit chip can produce amount of heat, heat
Side plate and radiator fins are transmitted to, are worked by piezoelectric ceramics combination fan, accelerate peripheral air movement, radiated in radiator
Increase forced air convection on the basis of radiating, can effectively reduce side board radiator temperature, and then reduce internal integrated circuit core
Piece temperature, improves stability, the reliability of whole machine work operation.
Beneficial effect：Compared with prior art, the closed case of utilization piezoelectric fan radiating of the present utility model, using pressure
Electroceramics fan is combined with closed case side board radiator, on the basis of the radiating of radiator natural radiation increases forced convertion,
Effective reduction radiator temperature, and then the operating temperature of closed case internal integrated circuit is reduced, improve the steady of electronic equipment
Qualitative, reliability.

Scope.
As shown in figure 1, the closed case radiated using piezoelectric fan, including case box 1, cabinet side board 2, piezoelectric ceramics
Combination fan 3, piezoelectric fan protective cover 4.Case box 1 is made of metal, and inside can fill some integrated circuit plates 5, machine
Case side plate 2 is the part for constituting casing, and side plate outer upper milling radiating fin 6, bottom install piezoelectric ceramics combination fan
Blade.Piezoelectric ceramics combination fan 3 is that multi-disc Piezoelectric Ceramic Fan blade 7 is installed in parallel on a support 8, in power supply
Under driving, 7 reciprocally swinging of piezoelectric fan blade plays fan effect.
When closed case works, internal integrated circuit chip can produce amount of heat, and heat is transmitted to side plate and radiator
Fin, is worked by piezoelectric ceramics combination fan, accelerates peripheral air movement, is increased strong on the basis of radiator heat loss through radiation
Cross-ventilation processed, can effectively reduce side board radiator temperature, and then reduce internal integrated circuit chip temperature, improve whole machine work
The stability of operation, reliability.
