Description

Header Coupling Structure of Parallel Flow Capacitor

The present invention relates to an outdoor unit of a package air conditioner, and more particularly, by arranging two header parts in parallel in an air conditioner outdoor unit and then welding and joining them in a connected state using a connector, parallelism can be improved. A header coupling structure of a flow capacitor.

Packaged air conditioners, which are widely used in homes and businesses, are divided into outdoor units and indoor units. The outdoor unit of the air conditioner is provided with a compressor for compressing the refrigerant, and a condenser for cooling and condensing the refrigerant compressed by the rotation of the cooling fan. In addition, the indoor unit is provided with an evaporator for cooling the ambient air by heat exchanged by the expanded refrigerant flowing through the expansion valve after passing from the condenser of the outdoor unit.

There are a number of capacitors used as outdoor units of package air conditioners, but some of the capacitors are configured by bending the condenser to reduce the installation space. Recently, a parallel flow condenser for automobiles (Parallel Flow Condenser, PF condenser) has been adopted in outdoor units of packaged air conditioners in order to improve cooling capacity and to share components.

1 is an exploded perspective view of an outdoor unit of an air conditioner showing a mounting structure of a general parallel flow capacitor. The overall configuration of the outdoor unit for a package air conditioner in which the PF condenser 30 is installed includes a base panel 10 installed on a rooftop or a floor of a building, and a compressor 20 disposed on the base panel 10 to compress a refrigerant. ), A motor fixing bracket 40 having a fan motor 50 for rotating the cooling fan 54, a mounting hole 42 to which the fan motor 50 is fixed, and a refrigerant compressed by the compressor 20. It consists of a PF condenser 30 which cools by the rotation of the cooling fan 54, and the front cover 60 and the rear cover 70 arrange | positioned at the front and the rear, respectively.

A fixing hole 44 coupled to the fixing hole 14 of the base panel 10 is formed at the lower end of the motor fixing bracket 40 by a fastening means, and the upper part of the PF capacitor 30 is inserted and fixed at the upper end thereof. The clamping part 48 is formed. The clamping portion 48 has a width slightly larger than that of the PF capacitor 30 and projects side by side downward. The central hole 56 of the cooling fan 54 is fixed on the drive shaft 52 of the fan motor 50 fixed to the mounting hole 42 of the motor fixing bracket 40.

An inlet hole 62 is formed in the front cover 60 constituting the front of the outdoor unit to allow external air to flow when the cooling fan 54 is rotated, and the plurality of heat dissipation grooves 72 are formed in the rear cover 70. Is formed so that the heated air is discharged to the outside through heat exchange.

Both sides of the PF capacitor 30 are attached with headers 32 and 34 through which refrigerant flows in and out, and a condenser fixing bracket 36 for fixing the PF capacitor 30 to the base panel 10 is attached to the bottom thereof. do. An insertion end 36a is formed in the condenser fixing bracket 36 so as to be fitted into the rib 12 formed in the base panel 10 during assembly.

Since the headers 32 and 34 of the PF capacitor 30 have a circular cross-sectional shape in a parallel flow capacitor having such a configuration, when the two capacitors are connected to each other, the headers are not bent in a straight line or bent in refrigerant. Since the centers of the flow tube insertion holes do not fit, there is a problem in that workability is reduced due to poor welding during welding of the refrigerant flow tube.

The present invention devised to solve this problem is to connect the parallel flow condenser in series with the center of the tube insertion hole by using a connector to combine, in order to improve the workability by making the welding work smoothly. The purpose is to provide a header coupling structure of a parallel flow capacitor.
