Abstract
The invention discloses an exhausting and sound deadening structure of a refrigerator compressor. The exhausting and sound deadening structure comprises a cylinder cover and a valve plate, wherein the cylinder cover is provided with a sound deadening cavity; the valve plate is connected with the end face of the sound deadening cavity; and a heat insulating layer is arranged on the inner surface of the sound deadening cavity. In the invention, the heat insulating layer is arranged in the sound deadening cavity to ensure that high-temperature high-pressure gas exhausted from a gas vent of the compressor is depressurized and silenced by the sound deadening cavity, the heat of the gas per se is blocked by the heat insulating layer and cannot be dissipated in a shell of the compressor through the cylinder cover or the valve plate and most of heat can only be exhausted via an exhaust path; and therefore, the complete machine shell temperature of the compressor can be reduced and the efficiency of the compressor is increased. The exhausting and sound deadening structure disclosed by the invention is suitable for serving as an exhaust system structure of the refrigerator compressor.
Description
Technical field
The present invention relates to a kind of exhaust system structure of compressor for refrigeration.
Background technique
Compressor for refrigeration comprises housing and is positioned at the cylinder assembly of housing, described cylinder assembly comprises cylinder seat and the cylinder head that connects with cylinder seat, cylinder seat internal mechanical structure has suction system and vent systems, plays air-breathing respectively and effect exhaust in the stroke of piston contact.And air-breathing and process exhaust all can produce noise owing to the variation of air pressure.Now on the market in the compressor product of main flow the noise reduction of air-breathing part all be to adopt the air suction silencer that plastic material is installed to realize, and vent systems is because exhaust pressure is big, working of plastics does not satisfy usage requirement, the former capital is to utilize silencing cavity on the cast iron cylinder head to realize the purpose of noise reduction, promptly the high temperature and high pressure gas of discharging in the exhaust port is fed from narrow passage in the silencing cavity that enlarges suddenly to volume, it is big that its gas volume becomes, and air pressure descends, thus noise reduction.But, such erasure effect is not fine, and the thermal conductivity of cast iron materials itself is than higher, and heat can be by the material own radiation in compressor housing under the gas of High Temperature High Pressure constantly impacts, cause the compressor housing temperature to raise, efficient reduces.
Summary of the invention
Purpose of the present invention is for a kind of compressor for refrigeration exhaust noise silencing structure is provided, and it has the advantages that can reduce the compressor housing temperature under the prerequisite of traditional silencing cavity effectively remaining with.
The solution that the present invention solves its technical problem is:
Compressor for refrigeration exhaust noise silencing structure, it comprises cylinder head with silencing cavity and the valve block that connects with the silencing cavity end face, the internal surface of described silencing cavity is provided with thermal-protective coating.
As further improvement in the technical proposal, be provided with the neck bush of fitting in the described silencing cavity with its internal surface, described neck bush is the macromolecular material member with bad thermal conductivity, constitutes described thermal-protective coating thus.
As further improvement in the technical proposal, described neck bush is the high-temperature resistance plastice member.
As further improvement in the technical proposal, be provided with pad between described valve block and the cylinder head.
The invention has the beneficial effects as follows: the present invention is by being provided with thermal-protective coating in silencing cavity, make the high temperature and high pressure gas of from the exhaust port of compressor, discharging on the one hand by silencing cavity step-down noise reduction, on the one hand itself heat is stopped by thermal-protective coating, and can not in the housing of compressor, distribute by cylinder head or valve plate, overwhelming majority heat can only be discharged from the exhaust passage, the complete machine case temperature of compressor can be lowered like this, thereby improves compressor efficiency.The present invention is applicable to that the exhaust system structure as compressor for refrigeration uses.
Description of drawings
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is an explosive view of the present invention.
Embodiment
With reference to Fig. 1～Fig. 2, compressor for refrigeration exhaust noise silencing structure, it comprises cylinder head 1 with silencing cavity 12 and the valve block 2 that connects with silencing cavity 12 end faces, the internal surface of described silencing cavity 12 is provided with thermal-protective coating.
Be further used as preferred embodiment, be provided with the neck bush 11 of fitting with its internal surface in the described silencing cavity 12, the macromolecular material member of described neck bush 11 for having bad thermal conductivity constitutes described thermal-protective coating thus.Certainly, in the middle of practical set, can be according to bubble-tight situation, add how suitable partition or pad or the like, as shown in Figure 2, install pad 3 and partition 4 additional between valve block 2 and neck bush 11, install suction valve chip 5 and valve plate pad 6 or the like additional between valve block 2 and its cylinder seat that will connect, these all are the structures that the suction and discharge part of conventional compressor for refrigeration is used always.
Be further used as preferred embodiment, described neck bush 11 is the high-temperature resistance plastice member.Neck bush 11 adopts the macromolecular material manufacturing with bad thermal conductivity, and preferred high-temperature resistance plastice material.
Though heat insulation noise reduction is respond well, but it is to be difficult to realize that the exhaust noise silencing structure of plastic material is want according to conventional method manufacturing, and the present invention can convert according to traditional cylinder head 1, the inner chamber part of promptly utilizing cylinder head 1 is as silencing cavity 12, neck bush 11 is arranged to the appearance similar with the top layer shape of silencing cavity 12, gets final product in the middle of during use neck bush 11 being put into silencing cavity 12.Neck bush 11 reinstalls pad 3, valve block 2 after packing in the cylinder head 1, just finishes assembling work of the present invention.Neck bush 11 itself pastes volt with the top layer of silencing cavity 12, and therefore also having formed a cavity volume is used for exhaust noise silencing, and its heat-shielding performance can reduce the enclosure interior temperature effectively.
More than be that better embodiment of the present invention is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
