Wind-guiding cover

Abstract

A wind-guiding cover is applicable to an electronic apparatus having a dissipating fan, a first heat-generating device and a second heat-generating device sequentially disposed along a straight line. The electronic apparatus further includes an upper lid. The wind-guiding cover includes a cover board for covering the first heat-generating device, and a plurality of side boards disposed on two sides of the cover board. The cover board is formed with a wind-guiding opening corresponding in position to the first heat-generating device. The side boards and the cover board form a first passageway. The wind-guiding opening and the upper lid form a second passageway. Therefore, airflow generated from the dissipating fan will be guided through the first passageway to dissipate heat generated from the first heat-generating device, and further through the second passageway to dissipate heat generated from the second heat-generating device.

1 . A wind-guiding cover applicable to an electronic apparatus comprising a dissipating fan, a first heat-generating device and a second heat-generating device disposed sequentially along a straight line, the electronic apparatus further comprising an upper lid, wherein the wind-guiding cover is located below the upper lid, the wind-guiding cover comprising;
 a cover board configured to cover the first heat-generating device and formed with a wind-guiding opening corresponding in position to the first heat-generating device, wherein a space is between the cover board and the upper lid; and   a plurality of side boards disposed on two opposite sides of the cover board, wherein the side boards and the cover board form a first passageway, the wind-guiding opening and the upper lid form a second passageway disposed above the first passageway and passing through the space airflow generated by the dissipating fan flows through the first passageway to dissipate heat generated from the first heat-generating device, and the airflow is further guided to pass through the second passageway to the second heat-generating device to dissipate heat generated from the second heat-generating device.   
     
     
         2 . The wind-guiding cover of  claim 1  further comprising two opposite ends, and an intake opening and a first outlet opening disposed on the two opposite ends respectively and connected with the first passageway, thereby guiding the airflow into the first passageway from the intake opening and out and away from the first outlet opening. 
     
     
         3 . The wind-guiding cover of  claim 2  further comprising a second outlet opening opposite to the intake opening and penetrating through the first passageway, wherein the electronic apparatus further comprises a third heat-generating device disposed between the intake opening and the second outlet opening. 
     
     
         4 . The wind-guiding cover of  claim 3 , wherein the third heat-generating device is a radiating block disposed on a Central Processing Unit (CPU). 
     
     
         5 . The wind-guiding cover of  claim 3  further comprising a shielding board disposed under the cover board to shield the second outlet opening. 
     
     
         6 . The wind-guiding cover of  claim 1  further comprising a flow-guiding board installed under the cover board at a position close to the intake opening, for guiding the airflow toward a direction of the first heat-generating device. 
     
     
         7 . The wind-guiding cover of  claim 1  further comprising an airtight strip installed on top of the cover board close to the edge of the wind-guiding opening to tightly connect the wind-guiding cover with the upper lid of the electronic apparatus, thereby preventing the airflow from dispersing from the second passageway. 
     
     
         8 . The wind-guiding cover of  claim 7 , wherein the airtight strip is made of rubber. 
     
     
         9 . The wind-guiding cover of  claim 1 , wherein the cover board is dimensioned to cover a part of the second heat-generating device and the wind-guiding opening thereof at least covers up the first heat-generating device. 
     
     
         10 . The wind-guiding cover of  claim 9 , wherein the wind-guiding opening extends to cover up the upper surface of the second heat-generating device. 
     
     
         11 . The wind-guiding cover of  claim 1 , wherein the cover board further comprises a ventilation gap connecting with the first outlet opening to correspond to the central region of the second heat-generating device. 
     
     
         12 . The wind-guiding cover of  claim 1 , wherein the first heat-generating device is a radiating block disposed on the central processing unit (CPU) while the second heat-generating device is a plurality of the random-access memories (RAM) configured to abreast from one another in the electronic apparatus. 
     
     
         13 . (canceled) 
     
     
         14 . The wind-guiding cover of  claim 1 , wherein the wind-guiding opening extends to cover up the upper surface of the second heat-generating device.
