Package-type scroll compressor

A package-type scroll compressor comprising:

• a scroll compressor element having an orbiting scroll which has scroll wraps on both sides of an end plate and two stationary scrolls each of which has a scroll lap meshing the scroll wrap of the orbiting scroll and forming a compression chamber with the scroll wrap of the orbiting scroll respectively;
• a motor for driving said scroll compressor element;
• a cooler for cooling an operation gas compressed in said scroll compressor element;
• a cooling fan disposed on one end of said motor for blasting cooling air subjected to heat-exchange with the operation gas by said cooler such that substantially all of the cooling air is provided to the compressor element via the cooling fan;
• a dryer for drying the operation gas cooled in said cooler;
• and
• a casing for accommodating these members,
• wherein said scroll compressor element is disposed above said motor, said dryer is disposed further above said scroll compressor element, through-holes for cooling are formed in the end plate of said orbiting scroll, cooling passages for cooling said scroll compressor element communicating the through -holes are formed in said scroll compressor element, and the cooling passages are arranged vertically such that a first portion of the cooling air flows inside of the compressor element and thereafter to the motor and a second portion of the cooling air flows over fans formed at side outer surfaces of the compressor element.
