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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean Patent Application No. 10-2010-0023686, filed on Mar. 17, 2010, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which in its entirety are herein incorporated by reference.BACKGROUND[0002]1. Field[0003]This disclosure relates to a distributor, and an evaporator and a refrigerating machine with the distributor, and more particularly, to a distributor which is improved to cause a cooling medium to form a stable flow and a steady circulation when flowing from a condenser into an evaporator, and an evaporator and a refrigerating machine with the distributor.[0004]2. Description of the Related Art[0005]In general, a vapor-compression refrigerating machine is composed of a compressor, a condenser, an expansion valve, and an evaporator.

AI Technical Summary

Benefits of technology

[0020]In accordance with the present disclosure, the cooling medium forms a stable flow and a steady circulation when flowing into the evaporator from the condenser and is supplied to the evaporator in a uniformly spread state. Thus, vibration of a liquid surface of the cooling medium in the evaporator is suppressed, and degradation of performance of the compressor due to liquid suction may be prevented.

[0021]Moreover, bubble generation that occurs in the liquid surface of the cooling medium is suppressed, so that heat transfer efficiency and the heat exchange performance of the evaporator are increased, thereby enhancing the performance and efficiency of the refrigerating machine.

Problems solved by technology

In the two-phase fluid cooling medium, the cooling medium in the gas state has much larger specific volume than the cooling medium in the liquid state, and a flow of the cooling medium in the liquid state is interfered with by the cooling medium in the gas state.

Therefore, the flow of the cooling medium is in unstable state, and the circulation is significantly amplified.

In addition, since the center of the distribution hole 18 faces the bottom of the evaporator directly below in the vertical direction, in a case where the cooling medium hits against the bottom of the evaporator, an influence of the collision becomes significant, and a liquid surface of the cooling medium of the evaporator fluctuates excessively.

During the suction of the cooling medium liquid and the bubbling liquid through a suction pipe 20, liquid suction into the compressor may result in degradation of the compressor performance.

Moreover, as bubbles are produced in the liquid surface of the cooling medium, heat transfer efficiency and heat exchange performance of the evaporator are further degraded.

As a result, in the existing distributor, due to the structural problems as described above, heat transfer efficiency and heat exchange performance of the evaporator are degraded, and the performance of the compressor is degraded due to excessive generation of bubbles and the liquid suction phenomenon.

Therefore, it is difficult to enhance the efficiency and performance of the refrigerating machine.
