Description

The vent silencer of reciprocating type refrigeration compressor

Technical field

The new construction arrangement that the utility model relates to be introduced into the vent silencer of reciprocating type refrigeration compressor.According to institute The acoustic filter for stating utility model includes the target for obviously allowing the actual use of industrial application, provides new arrangement, The new arrangement causes function to be improved, and more specifically generally leads to the optimization of the performance of reciprocating type refrigeration compressor.

Background technique

Firstly, it should be emphasized that, this owner was led to herein on September 16th, the 2009 patent document PI09035150 submitted Reference is crossed to be entirely incorporated into.

In this way, as described in the document, the raising of the performance of reciprocating type refrigeration compressor particularly with compression The temperature of the refrigerant fluid of the compression mechanism sucking of machine is related, and the temperature for the refrigerant fluid being inhaled into is lower, is pushed into use Will be lower in the temperature of the refrigerant fluid for the component for including refrigeration system, and therefore the thermodynamic efficiency of whole system is got over It is good.

Be maintained at suitable temperature in order to which refrigerant fluid will be sucked, patent document PI09035150 description particularly suitable for Be applied to the discharge tube of refrigerant fluid is thermally isolated device.In this scenario, the discharge tube be disposed in pipeline and In polymer isolating device, which is formed by two attachable plugs.

On the other hand, patent document CN202338461 describes a kind of scheme, in this scenario, particularly by that can seal The vent silencer for closing the reciprocating type refrigeration compressor of the metal body composition of ground limiting emission refrigerant fluid is covered by isolation Part surrounds, which is particularly made of nonmetallic materials.Document reasoning as mentioned, nonmetallic materials are (preferably Ground is polymer) have relative to the inside of metallic room and be preferably thermally isolated effect.However, because being exchanged to radiation Many heat of part, the discharge refrigerant fluid for including in metallic room are not isolated, this makes this scheme for tradition Be for refrigeration application it is inefficient, conventional refrigeration application in, discharge refrigerant fluid temperature be it is high, after all, pass through The part that radiation carries out heat exchange represents the half of the heat of all exchanges.

In this way, the premise of the current state based on the technology proposes the utility model.

Utility model content

In this way, the elementary object of the utility model is that the discharge of open reciprocating type refrigeration compressor is eliminated the noise Device, the heat which can reduce the enclosed environment of the inside of high temperature discharge refrigerant fluid and compressor case are handed over It changes.

In this way, a target of the utility model is to disclose a kind of acoustic filter, for by conduction and By the heat exchange of radiation, which is isolated with high-efficiency thermal.

Target summarized above sufficiently realized by the vent silencer of reciprocating type refrigeration compressor a kind of, the discharge Silencer includes: at least one enclosed body, which is connected at least one into pipeline and at least one A introduction pipe；Ontology is isolated at least one, which is mounted in the enclosed body, the closing sheet Body and the isolation ontology are spaced each other, to form heat transfer between the inside of enclosed body and the environment of isolation body exterior Isolation environment.In addition, the inside face of the isolation ontology include at least one reflecting region so as in the heat transfer isolation environment and Heat radiation separation layer is formed between the environment of the isolation body exterior.

According to the preferred embodiment of the utility model, it includes at least one dedicated for discharging lubricating oil that ontology, which is isolated, A through-hole and inside face that ontology is isolated is made of metal alloy has polishing finished surface.

Detailed description of the invention

The utility model will be described in detail based on the illustrative embodiments being listed below, in which:

Fig. 1 shows the vent silencer according to the utility model with partial exploded perspective view；And

Fig. 2 shows the vent silencer according to the utility model with lateral section.

Specific embodiment

As well known to the skilled person, it is common that reciprocating type refrigeration compressor includes that at least one discharge is eliminated the noise Device.

From function view, vent silencer includes ontology, and the inside of the ontology limits room (or volume), which can decay The pulse of refrigerant fluid is discharged, so that the noise from these pulsation is minimized.

Specifically, in closing reciprocating compressor, it is common that vent silencer is disposed in the inside of closure In.In this way, it is extremely important that, discharge conveyor, which is flowed to, from the compression cylinder of compression mechanism (passes through in its path Vent silencer) the temperature of discharge refrigerant fluid do not influence overall week of the closure filled with sucking refrigerant fluid Enclose temperature.

According to the utility model, as shown in Figures 1 and 2, vent silencer includes enclosed body 1 and isolation ontology 2, which is mounted on the whole surface region of the enclosed body 1.

It is connected into pipeline 3 and is made of to the enclosed body of introduction pipe 41 two metal parts, two metals Part is axially welded together in a manner of branch.Preferably, but being never limited in property, the inside of enclosed body 1 can wrap Wall and/or barrier are included, the wall and/or barrier can optimize the reduction for discharging the pulse of refrigerant fluid.

It means that when by isolated analysis, enclosed body 1 may be considered that similar to existing vent silencer and It is well-known to those skilled in the art.

In this way, the utility model has its maximum creativeness being carried out by increasing isolation ontology 2 Advantage.

Preferably particularly pertinent by the isolation ontology 2 that two equal parts of connection are formed because it by Metal alloy (preferably aluminium) is made, and since its inside face includes at least one region with polishing finished surface (that is, its face by using a series of mechanical friction processes of continuously thinner abrasive material at least one modified region) so as to Including low and uniform surface roughness.

As shown in Figure 2, enclosed body 1 and isolation ontology 2 are spaced each other in a manner of non-close.Preferably, the interval Depending on distance is deliberately controlled as the size difference between enclosed body 1 and isolation ontology 2 (the latter is greater than the former).

When in the closure for being inserted in refrigeration closing reciprocating compressor, the inside of enclosed body 1 is filled with discharge system Refrigerant flow (high pressure and high temperature), and the space between enclosed body 1 and isolation ontology 2 is filled with and is stored in Refrigerant fluid in the inside of closure, that is, sucking refrigerant fluid (low pressure and low temperature).

In this dynamic, the heat exchange by conduction between enclosed body 1 and the environment of closure passes through arrangement Refrigerant fluid between enclosed body 1 and isolation ontology 2 is minimized.The refrigerant fluid for including in this space is (excellent Selection of land is unrestricted) temperature and sucking refrigerant fluid in discharge refrigerant fluid (in the inside of enclosed body 1) Medium temperature between the temperature of (in the inside of sealing shell).

It is minimized by the burnishing surface that the heat exchange of radiation is isolated ontology 2.In this regard, it is notable that polishing Surface property is thermally isolated to those skilled in the art is known.

Optionally, as shown in fig. 1, at least one region that ontology 2 is isolated can also include dedicated for discharge lubrication The through-hole 21 of oil.

It is also important that the sole purpose of above description is describe the utility model by way of example especially real Apply example.It is therefore clear that in essentially the same way execute identical function with realize the element of identical result modification, Variation and tectonic association are maintained in protection scope defined in the appended claims.
