Technical Field

The invention relates to the technical field of refrigeration, in particular to a steam inlet assembly for a built-in oil separator, the built-in oil separator and a condenser.

Background

The refrigerant sprayed out of the compressor generally contains a large amount of lubricating oil, and if the refrigerant containing oil enters the condenser, a layer of oil film is formed on the cavity wall of the heat exchanger because the lubricating oil is not evaporated, so that the heat transfer effect and the refrigeration efficiency of the heat exchanger are greatly reduced. The current methods for solving the problem of oil films mainly comprise the following two methods: first, an oil separator is built in a compressor, and lubricating oil is separated by the oil separator before being discharged from the compressor, but the oil separation efficiency by this method is not very high, and the structure of the built-in oil separator in the compressor is complicated and installation is difficult; secondly, the oil separator is taken as an independent part and is arranged on the condenser, so that lubricating oil is separated by the oil separator before entering the condenser, and the structure of the external oil separator has the defects of high production cost, large occupied space, complex pipeline configuration, requirement of RT flaw detection, radiation and the like.

In order to overcome the disadvantages of the above two oil separator structures, an oil separator built in a condenser is proposed in the prior art. Several types of built-in oil separators have been disclosed, all of which are substantially similar in construction. The separation principle of the existing built-in oil separator is as follows: the oil-containing refrigerant enters the oil separator through the steam inlet pipe, the oil-containing refrigerant is subjected to collision separation, gravity settling, filter screen separation and other forms, the gaseous refrigerant enters the heat exchange tube area of the condenser, and the lubricating oil returns to the compressor from the oil return port, so that oil-gas separation is realized.

However, the applicant has found that the oil separators of the prior art have at least the following drawbacks:

(1) the steam inlet pipe is of a cylindrical structure with openings at two ends, oil-containing refrigerants enter from one end of the steam inlet pipe and then flow out from the other end of the steam inlet pipe into the oil separator, and due to the fact that an outlet of the steam inlet pipe is large, the oil-containing refrigerants flow out of the steam inlet pipe in a mixed flow mode, in the oil separator, the oil-containing refrigerants are in contact impact with and separate from the cavity wall of the oil separator in a mixed flow mode.

(2) Only one steam inlet of the built-in oil separator is positioned in the middle or one side of the shell of the condenser, and the steam inlet is single and is limited and inflexible when being matched with a unit; on the other hand, if the single steam inlet is positioned on one side of the condenser shell, the flow of the oil-containing refrigerant is longer, the vapor-liquid separation is not thorough, part of lubricating oil is attached to the pipe wall of the heat exchange pipe, and a heat exchange dead angle exists, so that the heat exchange efficiency cannot be improved.

Therefore, there is an urgent need for improvement of the prior art built-in oil separator.

Preferably, the aperture of the first flow equalizing hole 1011 is 10-20 mm, and the aperture of the second flow equalizing hole 1021 is 5-10 mm. It can be known that, when the first flow equalizing hole 1011 and the second flow equalizing hole 1021 are elliptical holes, the aperture of the first flow equalizing hole 1011 and the aperture of the second flow equalizing hole 1021 refer to the size of the major axis of the ellipse. In the preferred technical scheme of the embodiment, the size of the first flow equalizing hole 1011 is larger than that of the second flow equalizing hole 1021, so that more gas-liquid mixtures to be separated flow out from the side wall of the gas inlet pipe 101, the gas-liquid mixtures to be separated flowing out from the side wall are more easily contacted and collided with the oil separator, the gas-liquid separation effectiveness and efficiency can be further improved, and the gas-liquid separation efficiency can be further improved.
