Abstract

Ifølge foreliggende oppfinnelse er det tilveiebrakt en hul skovl (22) som omfatter et forkantveggparti (42), en flerhet hulrom (40), en eller flere tverribber (46), en flerhet kjøleåpninger (54) og en flerhet impulsåpninger (56). Hulrommene (40) er anordnet inn til forkantveggpartiet (42) mellom dette og en første ribbe (44). Tverribbene (46) strekker seg mellom forkantveggpartiet (42) og den første ribbe (44), og i det minste én tverribbe (46) er anordnet mellom et hulromspar (40). Kjøleåpningene (50) er anordnet i forkantveggpartiet (42) og tilveiebringer en passasje gjennom hvilken kjøleluft kan strømme ut av hulrommene. Impulsåpningene (56) er anordnet i den første ribbe (44) og danner en passasje gjennom hvilken kjøleluft kan strømme inn i hulrommene (40). I det minste én impulsåpning (56) grenser til en av tverribbene (46).
