Motor one somatotype compressor null for air conditioner

摘要

PURPOSE:To enable cooling of an element by utilizing a refrigerant without using a large aluminum block and an axial-flow fan by a method wherein a power semiconductor module is mounted on a shell to which a motor and an air conditioner are securely held in a closed state. CONSTITUTION:A motor integral type air conditioner comprises a motor 103 and a compressor 104. A suction port 105 and a delivery port 106 are formed in a shell 102 wherein the air conditioner is securely closed. A refrigerant in a low pressure low temperature state flows through a suction port to the shell and produces a high temperature high pressure refrigerant by means of a compressor 104 after the flow of it through the gap of the motor 103. The refrigerant flows through the delivery port 106 to the outside of the shell. For a feed to a motor armature, a power semiconductor module 101 is secured to the shell 102 by weld. A motor armature coil is connected to an output terminal 204, arranged in a shell, through wiring, and a power source and a control signal are connected to an input terminal 202 and a control terminal 203, arranged to the outside of the shell, through a wiring. A low temperature low pressure refrigerant cools a semiconductor module 101 before the refrigerator flows in the compressor 104.
