Outdoor unit and refrigerating device

Abstract

The invention provides an outdoor unit and a refrigerating device. The heat dissipation effect can be achieved with low cost and without upsizing of a shell even a special heat dissipation device is not installed additionally. The inside of the shell (31) is provided with a fan chamber (A) which comprises an evaporator (10) and fans (F) for cooling the evaporator, a mechanical chamber (B) which at least comprises a compressor (4) and an accumulator (3), and an electric fitting chamber which is disposed in the upper space of the upper side of the mechanical chamber across a rack and receives various electric fitting components including a converter used for controlling operation of the compressor. The mechanical chamber and the electric fitting chamber are isolated from the fan chamber through a separator horizontally; external air sucked in from an external air suction hole disposed in a back panel of the shell and is an area facing the accumulator is cooled and flows out to the fan chamber through a rainproof exhaust part of the separator after finally flowing through the converter disposed in the innermost part of the electric fitting chamber.

Description

technical field [0001] The present invention relates to a refrigerating device equipped with a compressor whose operation is controlled by an inverter, and more particularly to an outdoor unit and a refrigerating device provided with the outdoor unit. The cooling effect of the air inside the outdoor unit provided with a heat exchanger (functioning as a condenser). Background technique [0002] In the past, such as Figure 6 As shown, generally, the refrigerant circuit 100 of a refrigeration device generally includes a refrigeration cycle composed of a compressor 101, a condenser (outdoor heat exchanger) 102, a decompression device 103, and an evaporator (indoor heat exchanger) 104. The unit 101 , the condenser (outdoor heat exchanger) 102 , and the decompression device 103 are built in the outdoor unit 110 , and the evaporator (indoor heat exchanger) 104 is built in the indoor unit 120 . The high-temperature and high-pressure refrigerant compressed by the compressor 101 is ...

Problems solved by technology

However, when a general-purpose inverter is used, especially in the case of high-voltage operation, if an effective heat dissipation structure or heat removal structure is not adopted, it may not be possible to perform stable continuous operation, especially when the outside temperature is high, In high temperature areas, such as countries such as tropical areas, there will be problems that cannot be used directly
