Abstract
The invention discloses an outdoor unit of an inverter air conditioner, which comprises a chassis, a front panel, a compressor, a control box, a radiating flange and a radiating fan, wherein the chassis is arranged on the bottom of the outdoor unit, and parts of the outdoor unit can be mounted on the chassis; the front panel is arranged in front of the outdoor unit; the compressor is arranged on one side of the upper part of the chassis; the control box is arranged on one side of the lower part of the front panel; the radiating flange is arranged in the control box and behind a PCB; the radiating fan is arranged on one side of the back of the radiating flange; and an inlet pipe of the compressor is connected with a by-pass pipe which is wound into a snake shape behind the radiating flange. Because the by-pass pipe through which cooling medium passes is mounted behind the radiating flange of an inverter of the outdoor unit, the outdoor unit of an inverter air conditioner can effectively improve the radiating effect of the PCB and reduce the occurrence of halt and error reporting, thereby prolonging the service life of the inverter.
Description
Technical field
The present invention relates to air-conditioner, particularly relate to the off-premises station of frequency conversion type air conditioner.
Background technology
Recently, the use that utilizes an off-premises station to drive the frequency conversion type air conditioner of several indoor sets is increasing gradually.In the running of this air-conditioner, when off-premises station compresses a spot of cold-producing medium, in several compressors, only start the compressor of low capacity, and when compressing a large amount of cold-producing mediums, start jumbo compressor or start whole compressors.
As shown in Figure 1, existing frequency conversion type air conditioner comprises indoor set and off-premises station, and indoor set is connected by refrigerant piping with off-premises station.In detail, in above-mentioned indoor set, be provided with indoor heat converter 1.In off-premises station, be provided with the several compressors 3,4 of outdoor heat converter 2, compressed refrigerant; Fluid reservoir 6,7 is connected on the compressor 3,4, is used for providing to it cold-producing medium of gaseous state; Oil eliminator 9 is used for from the cold-producing medium recovered oil of compressor 3,4 outputs, and it is supplied to compressor 3,4; Cross valve 5 is used for the cold-producing medium after the compression optionally is supplied to indoor heat converter 1 or outdoor heat converter 2; Oil equalizing pipe 8 connects each compressor 3,4.
When freezing, by cross valve 5 gaseous refrigerant of the HTHP of compressor 3,4 output is delivered to outdoor heat converter 2 sides, constitute kind of refrigeration cycle; When air-conditioner heats, by cross valve 5 gaseous refrigerant of the HTHP of compressor 3,4 output is delivered to indoor heat converter 1 side, constitute and heat circulation.Again flow back in the compressor 3,4 behind refrigerant process cross valve 5 after heat exchange and the fluid reservoir 6,7, the refrigerant of this moment is the gaseous coolant of low temperature, low pressure.
In addition, referring to Fig. 2.In the off-premises station of the frequency conversion type air conditioner of prior art, the frequency converter (not shown) is installed in control box 10.The frequency converter of off-premises station can produce a large amount of heats in the course of the work, and for this reason, the back of the PCB in control box 10 (printed circuit board (PCB), not shown in the figures) is provided with fin 11, dispels the heat by radiator fan 12 air draughts.
But the frequency conversion type air conditioner of above-mentioned prior art has following shortcoming:
When the PCB in the off-premises station control box turned round under cooling condition, because the outside environment temperature is too high, PCB self also produced high temperature, and the radiating effect of fin 11 is not obvious, so the phenomenon that reports an error often occurs shutting down, greatly reduces the service life of frequency converter.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of radiating effect that can improve fin, prolong the off-premises station of the frequency conversion type air conditioner in frequency converter service life.
The objective of the invention is to be achieved through the following technical solutions:
A kind of off-premises station of frequency conversion type air conditioner comprises: the chassis that is arranged on the bottom of off-premises station and each parts of off-premises station can be installed on it; Be arranged on the front panel of off-premises station front; Be arranged on the compressor of top, chassis one side; Be arranged on the control box of front panel bottom one side; Be arranged in the control box, the fin of PCB back and the radiator fan that is arranged on fin back one side, it is characterized in that: be connected with a bypass pipe on the inlet tube of described compressor, bypass pipe becomes snakelike at the back face of fin.
One check valve that prevents the refrigerant adverse current is installed on the end away from suction port of compressor place of bypass pipe.
The caliber of above-mentioned bypass pipe is less than the caliber of the inlet tube of compressor.
Above-mentioned bypass pipe is along the back of laterally or vertically coiling at fin.
The off-premises station of frequency conversion type air conditioner of the present invention; owing to the bypass pipe that refrigerant passes through is installed in the fin back of off-premises station frequency converter; so can improve the radiating effect of PCB effectively, reduced and shut down the generation of phenomenon that reports an error, thus the service life of having improved frequency converter.

The specific embodiment
Describe below in conjunction with the off-premises station of accompanying drawing frequency conversion type air conditioner of the present invention.
As Fig. 3～shown in Figure 5, the off-premises station of air-conditioner of the present invention comprises: the chassis 20 that is arranged on the bottom of off-premises station and each parts of off-premises station can be installed on it; Be arranged on the front panel 28 of off-premises station front; Be arranged on the compressor 21 of top one side on chassis 20; Be arranged on the control box 22 of front panel 28 bottoms one side; Be arranged in the control box, the fin 23 of PCB back and the radiator fan 24 that is arranged on fin back one side.In order to improve the radiating effect of PCB, in the present invention, compressor 21 inlet tube 27 on be connected with a bypass pipe 25, bypass pipe 25 becomes snakelike at the back face of fin 23.Because it is lower to be back to the refrigerant temperature of compressor after heat exchange, so can reduce the radiating effect of PCB effectively.
In addition, in order to prevent the refrigerant adverse current in the bypass pipe 25, a check valve 26 that prevents the refrigerant adverse current is installed on the end away from the bypass pipe 25 of compressor 21 porch.In the present embodiment, bypass pipe 25 is along laterally dish is in the back of fin 23, and certainly, bypass pipe 25 also can longitudinally coil the back at fin 23.
Snakelike for the ease of bypass pipe 25 is curved, its caliber should be less than the caliber of the inlet tube of compressor; The material of bypass pipe 25 is identical with the material of compressor return duct.
