Description

Technical Field

[0001] This invention belongs to the field of refrigerated container technology, and particularly relates to a refrigerated container body component. Background Technology

[0002] Refrigerated containers are containers with insulated walls (including end walls and side walls), doors, bottom, and top that prevent heat exchange between the inside and outside. Refrigerated containers provide good insulation and maintain certain low temperatures, making them suitable for the transportation and storage of various perishable foods.

[0003] Refrigerated containers are generally large in size and contain a lot of goods, requiring a long unloading time. During unloading, the container doors cannot be closed, and a large amount of cold air will escape from the doors. In order to maintain the internal condition, the refrigeration system needs to continue to work to avoid affecting the refrigeration status of the products inside the container. As a result, the refrigeration system consumes more power due to the refrigeration work while the doors are open. Summary of the Invention

[0004] This invention provides a refrigerated container body assembly, which aims to solve the problem that the refrigeration system consumes more power due to refrigeration operation when the container door is open in order to maintain the stability of the internal state during the unloading process.

[0005] This invention is implemented as follows: a refrigerated container body assembly, applied to a container, the refrigerated container body assembly comprising:

[0006] An air inlet module and an air outlet module are provided. The air inlet module is installed in a first groove on the bottom plate of the container, and the air outlet module is installed in a second groove on the top plate of the container. A circulation pipe connects the air inlet module and the air outlet module. A first fan is installed on the circulation pipe. The first groove and the second groove are located near the door side of the container module.

[0007] The air inlet module, installed on the bottom plate, delivers the cold air that has settled above the bottom plate and is about to escape through the box door to the air outlet module under the negative pressure of the first fan. The cold air released by the air outlet module mixes with the hot air entering from the box door.

[0008] Preferably, the air inlet module includes an outer casing and a receiving cavity inside the outer casing.

The supporting grille is disposed above the collection chamber. The air inlet module and the air outlet module have the same structure, and the air inlet surface and the air outlet module are arranged in opposite directions inside the casing module.

[0009] During the diffusion of cold air, the air intake module absorbs the cold air that is about to escape. The air outlet module is located on the top plate. The air intake module recovers the cold air that is about to escape in batches and releases it back to the side of the box door near the top plate through the air outlet module, so as to neutralize the heat brought by the hot air from the outside and reduce the consumption of cold air inside the box module.

The compressor compresses the refrigerant, which then passes through the condenser and the main condenser to the evaporator. A condenser is also provided on the circulation pipe. The condenser is connected in series to the refrigeration system and is located between the compressor and the main condenser.

[0011] The condenser includes a right-angle plate, an outer arc cover, and an inner channel. The outer arc cover and the inner channel are both connected to the right-angle plate. The interior of the inner channel is a first channel, through which the refrigerant in the compressor reaches the main condenser. The gap between the outer arc cover and the inner channel is a second channel, through which the cold air drawn in by the air inlet module reaches the air outlet module.

[0012] The condenser serves as a supplement to the main condenser, reducing the power consumption of the main condenser by pre-condensing the high-temperature, high-pressure refrigerant gas.

[0013] Preferably, the condenser is installed on the outer wall of the housing module. The condenser is provided with a wind resistance airflow inlet unit and a wind resistance airflow outlet unit. The second channel in the condenser is connected to the outside through the wind resistance airflow inlet unit and the wind resistance airflow outlet unit. When the vehicle moves, the outside wind resistance airflow enters from the wind resistance airflow inlet unit, passes through the second channel, and leaves from the wind resistance airflow outlet unit.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0035] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] This invention provides a refrigerated container body assembly for use in containers. The container body is composed of a body module 100, which includes a top plate 110, a bottom plate 120, and side plates, a back plate, and a door connecting the top plate 110 and the bottom plate 120. A first groove and a second groove are respectively provided on the side of the top plate 110 and the bottom plate 120 near the door. Figures 1-7As shown, the refrigerated container body assembly includes:

[0037] An air inlet module 210 and an air outlet module 220 are provided. The air inlet module 210 is disposed in a first groove on the bottom plate 120, and the air outlet module 220 is disposed in a second groove on the top plate 110. A circulation pipe is provided between the air inlet module 210 and the air outlet module 220, and a first fan 230 is provided on the circulation pipe.

[0038] The air inlet module 210, which is installed on the base plate 120, delivers the cold air that has settled above the base plate 120 and is about to escape through the box door to the air outlet module 220 under the negative pressure of the first fan 230. The cold air released by the air outlet module 220 mixes with the hot air entering from the box door.

[0039] In this embodiment, the container module 100 serves as a storage area for refrigerated products. When the container door is opened, the air inlet module 210 and the air outlet module 220 are activated. Due to its density, the cold air inside the container module 100 is deposited in the space near the bottom plate 120. After the container door is opened, the cold air will diffuse to one side of the container door. The space near the top plate 110 of the container module 100 will have a low air density due to the descent of the cold air, making it easier for hot air from the outside to enter the container module 100 from the side of the container door near the top plate 110.

[0040] The air inlet module 210 is located on the bottom plate 120. During the diffusion of cold air, the air inlet module 210 absorbs the cold air that is about to escape. The air outlet module 220 is located on the top plate 110. The air inlet module 210 recovers the cold air that is about to escape in batches and releases it back to the side of the container door near the top plate 110 through the air outlet module 220, so as to neutralize the heat brought by the hot air from the outside, reduce the consumption of cold air inside the container module 100, and thus reduce the need for refrigeration. Here, the main purpose is to recover and reuse the cold air that is about to escape. By making reasonable use of the cold air, the waste caused by the cold air escaping to the outside and directly exchanging heat is reduced. By recycling and reusing, the demand for refrigeration is reduced, and the overall energy-saving effect of the refrigerated container is improved.

[0041] In a preferred embodiment of this invention, the air intake module 210 includes an outer casing 211 and a receiving cavity inside the outer casing 211. An inclined filter plate 213 is provided inside the receiving cavity, dividing it into a negative pressure chamber 214 and a collection chamber 215. A support grille 212 is positioned above the collection chamber 215. The first fan 230 is connected to the negative pressure chamber 214 via a pipe. The support grille 212 primarily serves as a support surface to prevent the grooved structure from affecting cargo transportation. The filter plate 213 acts as a filter screen to filter external impurities. The negative pressure chamber 214 absorbs cold airflow from the bottom of the casing under the negative pressure generated by the first fan 230.

[0042] The air inlet module 210 and the air outlet module 220 have the same structure. The air inlet surface and the air outlet module 220 are arranged in opposite directions in the housing module 100. The end face of the filter plate 213 near the support grille 212 is the air inlet surface. Since the air inlet module 210 and the air outlet module 220 have the same structure, the end face of the filter plate in the air outlet module 220 near the support grille is the air outlet surface. The air outlet surface faces the side where the housing door is located, and the air inlet surface faces the side of the back panel 130. The air inlet surface mainly recovers the outward-flowing air, and the air outlet surface releases cold airflow to combine with the inward-flowing hot air.

[0043] In a preferred embodiment of this invention, a condenser 400 is also provided on the circulation pipe. The condenser 400 includes a right-angle plate 401, an outer arc cover 402, and an inner channel 403. The inner channel 403 is a first channel. The outer arc cover 402 and the inner channel 403 are both connected to the right-angle plate 401. The gap between the outer arc cover 402 and the inner channel 403 is a second channel. The cold air drawn in by the air inlet module 210 reaches the air outlet module 220 through the second channel. The airflow direction in the second channel is opposite to the direction of gravity. The right-angle plate 401 and the outer arc cover 402 are both made of composite materials with heat insulation effect, and the inner channel 403 is made of a heat exchange material.

[0044] The housing module 100 is equipped with a refrigeration system, and the condenser 400 is connected in series with the refrigeration system.

[0045] In this embodiment, the refrigeration system is a prior art device, mainly providing a cooling effect within the cabinet module 100. The refrigeration system includes a main condenser 310, a compressor 320, an evaporator, and an internal fan. The compressor 320 compresses the refrigerant into a high-temperature, high-pressure refrigerant gas. After compression, the refrigerant passes through the first channel of the condenser 400 and the main condenser 310. The condensed refrigerant evaporates in the evaporator, carrying away heat from the air. The internal fan exchanges heat between the air inside the cabinet and the refrigerant flowing inside the evaporator.

[0046] In this embodiment, the condenser 400 is provided with an internal circulation outlet 411 and an internal circulation inlet 413 communicating with the second channel, and the condenser 400 is provided with a refrigerant inlet 412 and a refrigerant outlet 414 communicating with the first channel; the internal circulation inlet 413 is connected to the outlet of the first fan 230, the internal circulation outlet 411 is connected to the air outlet module 220, the refrigerant inlet 412 is connected to the compressor 320, and the refrigerant outlet 414 is connected to the main condenser 310;

[0047] The internal circulation outlet 411 and refrigerant inlet 412 are located at one end of the condenser 400, and the internal circulation inlet 413 and refrigerant outlet 414 are located at the other end of the condenser 400. The airflow direction between the second channel and the first channel is opposite. The condenser 400 serves as a cold airflow channel between the air inlet module 210 and the air outlet module 220, and also as a supplement to the main condenser 310. The power consumption of the main condenser 310 is reduced by the pre-condensation treatment of the high-temperature and high-pressure refrigerant gas by the condenser 400.

[0048] As a preferred embodiment of this example, the refrigeration system further includes a bypass pipe, one end of which is connected to the main condenser 310 and the other end of which is connected to the compressor 320. The function of the bypass pipe is to help the refrigeration system operate independently of the condenser 400, to meet the needs of working in more scenarios, and to avoid the refrigeration system passing through.

[0049] In a preferred embodiment of this invention, the condenser 400 is disposed on the outer wall of the housing module 100. The condenser 400 is provided with a wind resistance airflow inlet unit and a wind resistance airflow outlet unit. The second channel in the condenser 400 is connected to the outside through the wind resistance airflow inlet unit and the wind resistance airflow outlet unit. When the vehicle moves, the outside wind resistance airflow enters from the wind resistance airflow inlet unit, passes through the second channel, and leaves from the wind resistance airflow outlet unit.

[0050] The airflow resistance inlet unit includes a front sealing plate 431 and an airflow resistance inlet 432. The airflow resistance inlet 432 is disposed on the outer arc cover 402, and the front sealing plate 431 is deflected and abutted against the airflow resistance inlet 432. The airflow resistance outlet unit includes a rear sealing plate 421 and an airflow resistance outlet 422, and the rear sealing plate 421 is deflected and abutted against the airflow resistance outlet 422.

[0051] The front sealing plate 431 is located on the windward side of the outer arc cover 402. The windward side of the outer arc cover 402 adopts an arc-shaped structure. When the front sealing plate 431 and the rear sealing plate 421 are open, during vehicle operation, when the door is closed and the air intake module 210 and the air outlet module 220 do not need to be activated, the high-speed air passing through the wind resistance airflow outlet 422 and the wind resistance airflow inlet 432 will carry away the heat of the refrigerant flowing in the first channel, reducing the burden on the main condenser 310 during the condensation stage, and further reducing the energy consumption of the equipment during the refrigeration process.

[0052] A refrigerated container, the refrigerated container comprising the container assembly as described above.

[0053] After the refrigerated container door is opened, the air intake module 210 and the air outlet module 220 will be activated. The air intake module 210 and the air outlet module 220 work together to circulate the cold air that is about to escape, reducing the cooling pressure on the refrigeration system when the door is open. Furthermore, the cold air is introduced into the condenser 400 as a supplement to the main condenser 310, reducing the refrigerant condensation power consumption required by the refrigeration system that is in operation.

[0054] Meanwhile, when the air intake module 210 and the air outlet module 220 are not working, the condenser 400 starts the air resistance airflow channel formed by the air resistance airflow inlet unit and the air resistance airflow outlet unit. During the vehicle's driving process, the airflow passing through the air resistance airflow channel will carry away the heat outside the second channel, which serves as a supplement to the condensation of the main condenser 310 and reduces the condensation pressure of the main condenser 310.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
