[0032] The vertical corner of the container 1 is where the refrigeration unit is installed.
[0033] The first sound-absorbing door body 2 and the second sound-absorbing door body 3 are both detachably mounted on the container 1, and the mounting method may be hinges, articulations, or the like.
[0034] In this embodiment, the muffler is made into an openable and closable door structure, which can facilitate the entry and exit of personnel and the transportation of equipment inside the container 1.
[0035] Embodiment 2: See attached Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, this embodiment is a further improvement on the basis of the first embodiment, and its specific method is: the first silencer door body 2 is provided with an air inlet area 4, and the second silencer door body 3 is provided with an air exhaust area 5, and the air inlet area 4 and the air exhaust area 5 are both provided with a plurality of ventilation holes. Among them, fans are provided on the inner sides of the first silencer door body 2 and the second silencer door body 3 to achieve air intake and exhaust. In this embodiment, ventilation holes are provided on both the first silencer door body 2 and the second silencer door body 3, which can reduce noise while increasing the ventilation rate, and play the effect of heat dissipation and cooling of internal equipment.
[0036] Embodiment 3: See attached Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, this embodiment is a further improvement based on the second embodiment, and its specific method is: the aperture of the ventilation holes in the air inlet area 4 and the air exhaust area 5 are both 3mm~6mm, and the opening rate of the air inlet area 4 and the opening rate of the air exhaust area 5 are both 19%~44%.
[0037] The opening ratio of the air inlet area 4 refers to the opening ratio of the air inlet area 4 relative to the first sound-absorbing door body 2. When the opening ratio is 19%, the air inlet area 4 is located on one of the side surfaces of the first sound-absorbing door body 2, and when the opening ratio is 44%, the air inlet area 4 is located on one or both side surfaces of the first sound-absorbing door body 2.
[0038] The opening ratio of the exhaust area 5 refers to the opening ratio of the exhaust area 5 relative to the second sound-absorbing door body 3. When the opening ratio is 19%, the exhaust area 5 is located on one of the side surfaces of the second sound-absorbing door body 3, and when the opening ratio is 44%, the exhaust area 5 is located on one, two or more surfaces of the second sound-absorbing door body 3.
[0039] When the aperture of the ventilation hole is 3 mm, the opening rate of the air inlet area 4 may be 44%; when the aperture of the ventilation hole is 6 mm, the opening rate of the air inlet area 4 may be 19%.
[0040] The design of the ventilation holes not only blocks the noise of the refrigeration unit inside container 1, but also has excellent ventilation effect, with a noise reduction of up to 25dB and a ventilation volume of up to 24000m 3 / min.
[0041] In this embodiment, the aperture and opening ratio of the ventilation holes are designed to ensure the air flow between the inside and outside of the silencer door while ensuring the sound insulation effect, thereby achieving a good heat dissipation effect.

[0043] In the specific implementation process, the containers 1 are usually placed side by side and at a relatively close distance. If the air inlet area 4 is set on the side parallel to the installation surface of the container 1, the air flow will be blocked by the adjacent container 1, affecting the air intake effect; there is an air circulation channel between the containers 1, and the air inlet area 4 is set in the direction of the channel, which ensures the circulation of the air flow in the air inlet area 4. When there is a severe weather environment such as rain, snow, hail, etc., the exhaust area 5 in the lower part can be blocked by the adjacent container 1, and rainwater is not easy to blow into the exhaust area 5.
[0044] In this embodiment, the air inlet area 4 is arranged on the side of the installation surface, which can achieve a better ventilation effect; the exhaust area 5 is arranged on the lower half of the bottom surface and the side surface, which can prevent rainwater from entering and ensure the ventilation effect.

In this embodiment, the opening and closing angles of the first silencer door body 2 and the second silencer door body 3 are set to 120°, which better facilitates the entry and exit of personnel and equipment in the container 1.
[0046] Embodiment 6: See attached Figure 1 and attached Figure 4 As shown, this embodiment is a further improvement on the first embodiment, and its specific method is as follows: the first silencer door body 2 and the second silencer door body 3 are both rectangular cover structures, and the adjacent surfaces of the two are provided with avoidance structures 6.
[0047] The avoidance structure 6 can be designed according to the interference space that the two doors will encounter when opening the door respectively. It can be a recessed structure or a beveled structure, so that the two doors will not be interfered when opening the door respectively.
[0048] As attached Figure 2 As shown, a corresponding avoidance structure 6 is provided on the second sound-absorbing door body 3, so that a larger opening angle can be obtained when the first sound-absorbing door body 2 is opened.
