PURPOSE:To minimize the size and the weight of a cooling system of a car fan using a heat pipe by furnishing the pipe inside a shaft for absorbing the inside heat of a motor into a thick flesh part of the fan. CONSTITUTION:A heat pipe 1a is mounted inside a shaft 1 of a motor M and constructed to radiate heat at a boss part 2 of a sirocco fan made of aluminum and the like. This construction permits to minimize the size and the weight without providing an exclusive radiation member in a sealed construction and improve fire and dust proof efficiencies. |
