Description

Fan filter unit shock attenuation mainboard

Technical Field

The utility model relates to a mainboard technical field specifically is a fan filter unit shock attenuation mainboard.

Background

The fan filter unit is an air supply filter device with power, and has a modular tail end air supply device with a filtering effect. The fan filter unit sucks air from the top and filters the air through the high-efficiency air filter, and the filtered clean air is uniformly sent out at the speed of about 0.45m/s +/-20% on the whole air outlet surface.

The fan filter unit sucks air by using a motor and an impeller in the fan filter unit, the sucked air passes through a high-efficiency air filter or an ultra-high-efficiency filter screen below the fan filter unit to filter out large-particle dust particles in the air, and finally the fresh air is uniformly delivered to a clean room at the air speed of 0.45m/s +/-10%.

When the fan filter unit operates, the fan filter unit is easy to vibrate due to the rotation of the motor and the impeller, so that the main board of the fan filter unit is easy to damage under the vibration condition.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to foretell not enough, provide a fan filter unit shock attenuation mainboard, this kind of shock attenuation mainboard simple structure has stronger shock-absorbing capacity.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a fan filter unit shock attenuation mainboard, includes mainboard, casing, shock attenuation post and heat conduction silica gel, the upper and lower inner wall of casing is all fixed and is equipped with a plurality of shock attenuation posts, the mainboard presss from both sides and establishes between the shock attenuation post in the top and the shock attenuation post of below, the lateral wall of mainboard passes through a plurality of springs and casing elastic connection, the upper and lower two sides of mainboard all are attached to heat conduction silica gel.

Further, the shock attenuation post includes shock attenuation casing and damping spring, the vertical fixed damping spring that is equipped with in the shock attenuation casing, the shock attenuation casing is made by rubber materials, open the shock attenuation casing both sides has the venthole.

Further, the surface of the contact end of the shock absorption column and the main plate is a smooth surface.

Further, the area of heat conduction silica gel matches with the mainboard area.

Furthermore, six surfaces of the shell are provided with a plurality of air holes.

The utility model has the advantages that:

in practical application, the mainboard can dissipate heat through the heat-conducting silica gel and also has a dustproof effect, one end of the shock absorption column is in soft contact with the mainboard, so that the mainboard cannot be damaged, and meanwhile, a shock absorption effect is well achieved; the utility model discloses simple structure, and have stronger shock-absorbing capacity and heat-sinking capability.

Detailed Description

As shown in fig. 1 to 3, a fan filter unit shock attenuation mainboard includes mainboard 1, casing 2, shock absorber 3 and heat conduction silica gel 5, the upper and lower inner wall of casing 2 all fixes and is equipped with a plurality of shock absorber 3, mainboard 1 presss from both sides and establishes between the shock absorber 3 of the shock absorber 3 in the top and the shock absorber 3 of below, the lateral wall of mainboard 1 passes through a plurality of springs 4 and casing 2 elastic connection, the upper and lower two sides of mainboard 1 all are attached to heat conduction silica gel 5.

In practical application, the mainboard can dissipate heat through the heat-conducting silica gel and also has a dustproof effect, one end of the shock absorption column 3 is in soft contact with the mainboard, the mainboard 1 cannot be damaged, and meanwhile, a good shock absorption effect is achieved; the utility model discloses simple structure, and have stronger shock-absorbing capacity and heat-sinking capability.

As shown in fig. 1 to 3, the shock absorbing column 3 includes a shock absorbing housing 31 and a shock absorbing spring 32, the shock absorbing spring 32 is vertically fixed in the shock absorbing housing 31, the shock absorbing housing 31 is made of rubber material, and air outlets 33 are formed on two sides of the shock absorbing housing 31. In this embodiment, shock-absorbing column 3 is elastic contact with mainboard 1, and because of the contact surface is rubber materials, also is soft contact between shock-absorbing column 3 and the mainboard 1, consequently under this kind of duplicate protection, this kind of fan filter unit shock attenuation mainboard has stronger shock-absorbing capacity.

As shown in fig. 1 to 3, the surface of the shock absorbing column 3 at the end contacting the main plate 1 is a smooth surface. In this embodiment, when the shock absorbing column 3 contacts with the main board 1, the contact can better protect the main board from being damaged.

As shown in fig. 1 to 3, the area of the heat conductive silicone rubber 5 matches the area of the motherboard 1. In this embodiment, heat conduction silica gel 5 can increase heat radiating area, has also played dirt-proof effect simultaneously, has protected mainboard 1 well, effectively prolongs the life of mainboard.
