Title:
Refrigerating device
Document Type and Number:
Japanese Patent JP6000000
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a freezer unit capable of improving heat radiation performance and preventing the damage of a semiconductor power device which is caused by vibrations of a discharge pipeline.SOLUTION: In a freezer unit, a compressor 101, a heat source side heat exchanger 103, an expansion valve 106, and a utilization side heat exchanger 107 are connected by a refrigerant pipeline, and the freezer unit includes a refrigerant circuit 1 for circulating a refrigerant. The freezer unit includes: an inverter device 312 which includes a switching element 60 formed by a wideband gap semiconductor and drives the compressor 101; and a muffler 200 which is provided at a discharge pipeline 44 connected with the discharge side of the compressor 101 from among the refrigerant pipeline, the muffler 200 in which an acoustic structure for cancelling vibrations of the discharge pipeline 44 is formed. The muffler 200 is provided at a position facing the switching element 60 and conducts heat exchange between the refrigerant of the discharge pipeline 44 and heat of a power device.
