Filter, cooling injection member, and cooling wind injection method

Abstract

Filter ( 304 ) disposed between a wind blower and injection port ( 302 ) that injects cooling wind delivered from said wind blower and in which a plurality of opening portions are formed, wherein an area of said filter ( 304 ) is greater than an area of said injection port ( 302 ), an area of each of said plurality of opening portions is smaller than the area of said injection port ( 302 ), and a total area of said plurality of opening portions is 1 to 5 times greater than the area of said injection port ( 302 ).

1 . A filter disposed between a wind blower and an injection port that injects cooling wind delivered from said wind blower and in which a plurality of opening portions are formed,
 wherein an area of said filter is greater than an area of said injection port, an area of each of said plurality of opening portions is smaller than the area of said injection port, and a total area of said plurality of opening portions is 1 to 5 times greater than the area of said injection port.   
     
     
         2 . A cooling injection member, comprising:
 a filter in which a plurality of opening portions are formed and that allows cooling wind delivered from a wind blower to pass through; and   an injection port that injects said cooling wind that has passed through said filter,   wherein an area of said filter is greater than an area of said injection port, an area of each of said plurality of opening portions is smaller than the area of said injection port, and a total area of said plurality of opening portions is 1 to 5 times greater than the area of said injection port.   
     
     
         3 . The cooling injection member according to  claim 2 , further comprising:
 a part having a wall surface with which cooling wind that passes through said opening portions collides, said part being disposed between said filter and said injection port.   
     
     
         4 . The cooling injection member according to  claim 2 , further comprising:
 a masking plate, on whose outer circumference notch portions are formed and that masks a wind path of said cooling wind that passes through said opening portions.   
     
     
         5 . The cooling injection member according to  claim 2 , further comprising:
 a plurality of said filters.   
     
     
         6 . The cooling injection member according to  claim 5 ,
 wherein said plurality of filters are fixed to said cooling injection member in such a manner that a wind path of said cooling wind, that passes through said opening portions formed in one of said plurality of filters, is different from a wind path of said cooling wind that passes through said opening portions formed in another one of said plurality of filters.   
     
     
         7 . A cooling wind injection method, comprising:
 providing a wind blower and a filter disposed between said wind blower and an injection port that injects cooling wind delivered from said wind blower and in which a plurality of opening portions are formed;   causing an area of said filter to be greater than an area of said injection port;   causing an area of each of said plurality of opening portions to be smaller than the area of said injection opening; and   causing a total area of each of said plurality of opening portions to be 1 to 5 times greater than the area of said injection port.   
     
     
         8 . The cooling wind injection method according to  claim 7 , further comprising:
 providing a part having a wall surface with which cooling wind that passes through said opening portions collides, said part being disposed between said filter and said injection port.   
     
     
         9 . The cooling wind injection method according to  claim 7 , further comprising:
 providing a masking plate, on whose outer circumference notch portions are formed and that masks a wind path of said cooling wind that passes through said opening portions.   
     
     
         10 . The cooling wind injection method according to  claim 7 , further comprising:
 providing a plurality of said filters.   
     
     
         11 . The cooling wind injection method as set forth in  claim 10 , further comprising:
 wherein said plurality of filters are fixed to said cooling injection member in such a manner that a wind path of said cooling wind, that passes through said opening portions formed in one of said plurality of filters, is different from a wind path of said cooling wind that passes through said opening portions formed in another one of said plurality of filters.   
     
     
         12 . The cooling injection member according to  claim 3 , further comprising:
 a plurality of said filters.   
     
     
         13 . The cooling injection member according to  claim 4 , further comprising:
 a plurality of said filters.   
     
     
         14 . The cooling wind injection method according to  claim 8 , further comprising:
 providing a plurality of said filters.   
     
     
         15 . The cooling wind injection method according to  claim 9 , further comprising:
 providing a plurality of said filters.
