Description

Technical Field

[0001] This utility model relates to the field of compressor silencing technology, specifically to a gapless direct intake silencing pipe. Background Technology

[0002] The intake silencer is a key component installed near the intake port of the compressor's lower casing. Its main purpose is to reduce the noise generated by the compressor during the intake process and improve the smoothness of airflow. Common locations for intake silencers in the compressor's lower casing include... Figure 5 As shown, the air inlet of the air intake silencer chamber and the air intake pipe port adopt a non-direct connection structure layout, with a reserved design spacing to form an indirect air intake method.

[0003] Traditional intake silencers rely on large-volume designs to achieve wide-band noise reduction. Their built-in sound-absorbing materials or labyrinth structures can easily create intake resistance, leading to a decrease in the compressor's intake pressure gradient and a reduction in system cooling efficiency. If the cavity structure design parameters are unbalanced, localized airflow vortices can easily form, causing increased ineffective energy consumption and thus weakening the compressor's effective cooling output. The presence of sound-absorbing media or labyrinth-style flow guide structures can exacerbate the system pressure drop gradient, forcing the compressor to maintain a higher compression ratio, which in turn leads to increased power consumption and a decrease in COP (Coefficient of Performance). Long-term operating conditions have verified that oil deposits and material aging significantly increase the flow resistance coefficient, ultimately causing the COP to decline at an accelerated rate.

[0004] There is currently no effective solution to the above problems. Utility Model Content

[0005] In view of the above-mentioned technical problems in related technologies, this utility model proposes a gapless direct air intake silencer tube, which can overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0007] A gapless direct intake muffler includes a muffler body, which is composed of several interconnected pipes that are not on the same horizontal line. The front end of the muffler body is connected to the compressor cylinder head through a locking device one, and the end of the muffler body is connected to the inlet of the intake pipe located on the housing through a locking device two.

[0008] Furthermore, the pipeline includes a straight pipe one, a straight pipe two, and a straight pipe three. The straight pipe one and the straight pipe two are connected by a bend one, and the straight pipe two and the straight pipe three are connected by a bend two.

[0009] Furthermore, the straight pipe is vertically installed inside the lower housing of the compressor.

[0010] Furthermore, the second straight pipe is lower than the third straight pipe.

[0011] Furthermore, the end of the straight pipe three is connected to the locking device two via the bent pipe three.

[0012] Furthermore, the end of the straight pipe is connected to the locking device.

[0013] Furthermore, the pipe is made of corrosion-resistant engineering plastics or high-strength aluminum alloy or stainless steel.

[0014] The beneficial effects of this utility model are as follows: This utility model replaces the original silencer cavity with a silencer pipe, and the intake pipe is directly connected to the silencer pipe, which maximizes the intake efficiency. Moreover, the refrigerant enters the cylinder directly without being lost into the shell. The high-temperature refrigerant inside the shell will not be drawn into the cylinder. Only low-temperature and low-pressure refrigerant enters the cylinder. Due to its low temperature, low pressure, and high density, the unit refrigerant drawn into the cylinder can draw in more units of refrigerant, thereby increasing the amount of refrigerant compressed. Therefore, the intake efficiency is improved, the loss is reduced, and the cooling capacity is increased. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, a gapless direct intake muffler pipe according to an embodiment of the present utility model includes a muffler pipe body 1. The muffler pipe body 1 is composed of several interconnected pipes that are not on the same horizontal line. The front end of the muffler pipe body 1 is connected to the compressor cylinder head through a locking device 1 2, and the end of the muffler pipe body 1 is connected to the inlet of the intake pipe 4 located on the housing through a locking device 2 3.

[0024] In this embodiment, the pipeline includes a first straight pipe 5, a second straight pipe 6, and a third straight pipe 7. The first straight pipe 5 and the second straight pipe 6 are connected by a first bend 8, and the second straight pipe 6 and the third straight pipe 7 are connected by a second bend 9.

[0025] In this embodiment, the straight pipe 5 is vertically installed inside the lower housing of the compressor.

[0026] In this embodiment, the second straight pipe 6 is lower than the third straight pipe 7.

[0027] In this embodiment, the end of the straight pipe 3 7 is connected to the locking device 2 3 via the bend pipe 3 10.

[0028] In this embodiment, the end of the straight pipe 5 is connected to the locking device 2.

[0029] In this embodiment, the pipe is made of corrosion-resistant engineering plastics or high-strength aluminum alloy or stainless steel.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0031] In practical use, the gapless direct intake silencer pipe described in this utility model abandons the traditional silencer cavity structure design and adopts an integrated hollow straight-through airflow channel solution, such as... Figure 2As shown, the front end is integrated with the compressor cylinder head, and the connection is made using fastening device one. The end is connected to the intake pipe inside the housing using fastening device two, achieving zero-gap direct intake functionality. Lightweight, corrosion-resistant engineering plastics or high-strength aluminum alloy / stainless steel are selected as materials.

[0032] The effect of a gapless direct intake silencer pipe in the lower casing of the compressor is as follows: Figure 3 As shown:

[0033] The intake pipe and connecting pipe are directly connected to maximize intake efficiency, allowing the refrigerant to enter the cylinder directly without any loss of refrigerant into the casing.

[0034] Because of the direct connection, the high-temperature refrigerant inside the casing is not drawn into the cylinder. Only low-temperature, low-pressure refrigerant enters the cylinder. Due to its low temperature, low pressure, and high density, the cylinder can draw in more refrigerant per unit volume, thus increasing the amount of refrigerant compressed. This improves suction efficiency, reduces losses, and increases cooling capacity.

[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, the original silencer cavity is replaced by a silencer pipe, and the intake pipe is directly connected to the silencer pipe, which maximizes the intake efficiency. Moreover, the refrigerant enters the cylinder directly without being lost into the housing. The high-temperature refrigerant inside the housing is not drawn into the cylinder, and only low-temperature, low-pressure refrigerant enters the cylinder. Due to its low temperature, low pressure, and high density, the unit refrigerant drawn into the cylinder can absorb more units of refrigerant, thereby increasing the amount of refrigerant compressed. Therefore, the intake efficiency is improved, losses are reduced, and the cooling capacity is increased.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
