Distributor, and evaporator and refrigerating machine with the same

Abstract

Provided are a distributor having a distribution tube having an inner surface formed as a curved surface, a plurality of distribution holes which are formed in a lower semicircular region of the distribution tube with respect to a horizontal line of the distribution tube and are arranged to be symmetrical about a vertical line of the distribution tube and a connection hole provided in the distribution tube so that the distribution tube is connected to a connection tube, an evaporator and a refrigerating machine with the distributor. A perforated plate may be fixed to an inside of the distribution tube so as to block a flow path of a cooling medium. The distributor is capable of forming a stable flow and a steady circulation while a cooling medium flows from a condenser into an evaporator and a steady circulation are formed and spread uniformly and supplied tp the evaporator.

Description

technical field [0001] The present invention relates to a distributor, an evaporator and a refrigerating machine having the distributor, and more particularly to an improved distributor for forming a smooth flow and a stable circulation of the cooling medium when flowing from the condenser into the evaporator , and the evaporator and refrigerator with this distributor. Background technique [0002] Generally, a vapor compression refrigerator consists of a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle of this vapor compression refrigerator can be roughly described as: the gaseous cooling medium is compressed by the compressor to a relatively high pressure, and is supplied to the condenser, releases heat, and is subsequently condensed into a liquid state. [0003] The condensed liquid cooling medium flowing through the expansion valve (usually through the expansion valve, capillary, orifice, expansion turbine, etc.) is throttled to a relative...

AI Technical Summary

Problems solved by technology

Therefore, the flow of the cooling medium is in an unstable state, and the circulation is significantly enlarged

[0009] In addition, since the center of the distribution pipe 18 faces the bottom of the evaporator directly downward in the vertical direction, when the cooling medium hits the bottom of the evaporator, the impact of the collision becomes significant, and the liquid level of the cooling medium of the evaporator will be excessively volatile

During the suction of the cooling medium liquid and the bubbling liquid through the suction pipe 20, the suction of the liquid in the compressor causes the performance of the compressor to decrease.

Moreover, due to the generation of foam on the liquid surface of the cooling medium, the heat transfer efficiency and heat exchange performance of the evaporator are further reduced

[0010] Therefore, in the existing distributor, the heat transfer efficiency and heat exchange performance of the evaporator are lowered due to the structural problems as described above, and the performance of the compressor is lowered due to the excessive generation of foam and the phenomenon of liquid suction.

Therefore, it is difficult to improve the efficiency and performance of the refrigerator
