Benefits of technology

[0006]The embodiment relates to a connection pipe. In the embodiment, a flow cross-sectional area of a portion of channels provided inside the connection pipe that connects two refrigerant pipes is reduced so that liquid-phase refrigerant and gas-phase refrigerant flowing through the channels are mixed. Therefore, the embodiment has an advantage in that the refrigerant flowing through the inside of the refrigerant can be flowed evenly irrespective of the phase.

Problems solved by technology

Therefore, a problem may arise in that the refrigerant flowing inside the refrigerant pipe cannot be evenly flowed inside the refrigerant pipe according to the phase.

first embodiment

[0012]Hereinafter, the constitution of a connection pipe according to the present invention will be described in more detail with reference to the accompanying drawings.

[0013]FIG. 1 is a longitudinal sectional view showing the first embodiment of the connection pipe according to the present invention.

[0014]Referring to FIG. 1, the connection pipe 100 serves to connect first and second refrigerant pipes 10 and 20 (see FIG. 2) adjacent to each other. The connection pipe 100 includes a connection pipe main body 110 and a plurality of channels 120. The connection pipe main body 110 includes first and second coupling parts 111 and 113 and a mixing part 115, and the channel 120 includes inlet and outlet channels 121 and 123 and a mixing channel 125.

[0015]More specifically, the first and second coupling parts 111 and 113 are provided at both ends of the connection pipe main body 110, respectively, as shown in the drawing. The first and second coupling parts 111 and 113 are places where the...

second embodiment

[0030]Hereinafter, the constitution of a connection pipe according to the present invention will be described in more detail with reference to the accompanying drawings.

[0031]FIG. 3 is a longitudinal sectional view showing the second embodiment of the connection pipe according to the present invention.

[0032]Referring to FIG. 3, the connection pipe 200 according to the embodiment includes first and second coupling parts 211 and 213 and a mixing part 215. Inlet and output channels 221 and 223 and a mixing channel 225 are provided inside the connection pipe 200, and a flow interfering part 230 is provided on the mixing channel 225. The constitution of the embodiment as described above is the same as the aforementioned first embodiment.

[0033]Guide surfaces 231 are provided at upper and lower surfaces of the flow interfering part 230 that the upstream side of the inlet channel 221 and the downstream side of the outlet channel 223 face each other on the drawing. The guide surfaces 231 are...

Abstract

The embodiment provides a connection pipe and a refrigerant flowing system comprising the same. The connection pipe and the refrigerant flowing system include: a connection pipe main body of which both ends are coupled to first and second refrigerant pipes through which refrigerant is flowed and that has a channel through which refrigerant transferred from the first refrigerant pipe to be transferred to the second refrigerant pipe is flowed; and a flow interfering part that is provided on the channel to interfere the flow of the refrigerant in the direction transferred from the first refrigerant pipe to the channel.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The embodiment relates to an air conditioner, and more particularly, to a connection pipe that connects refrigerant pipes through which refrigerant is flowed and a refrigerant flowing system comprising the same.[0003]2. Description of the Related Art[0004]In general, an air conditioner is an electric home appliance that keeps the room cool or heat. The air conditioner as above includes an outdoor unit and an indoor unit, and keeps the room cool or heat as refrigerant circulating the outdoor unit and the indoor unit performs a heat-exchange with outdoor air and indoor air. Refrigerant pipes are provided for circulating the refrigerant. A connection pipe is also provided for connecting the ends of the refrigerant pipes adjacent to each other. One ends of the refrigerant pipes adjacent to each other are inserted into both ends of the connection pipe, respectively.[0005]However, when any one of the refrigerant pipes connect...
