Description

Technical Field

[0001] This invention relates to the field of new energy technology, specifically a phase change cooling mobile supercharging device. Background Technology

[0002] With the development and popularization of new energy vehicles, the demand for charging piles is becoming increasingly urgent. However, the coverage of fixed charging piles on highways (especially in remote areas) is currently insufficient, which cannot meet the rapid growth of new energy vehicles and has also created a strong demand for mobile charging.

[0003] The biggest technological bottleneck for mobile charging stations is the rapid heat dissipation problem caused by supercharging. Conventional DC charging stations typically limit their current to below 250A during operation to ensure stability and safety. However, with the development of super-fast charging technology, charging stations can now withstand currents as high as 500A, greatly improving charging efficiency but also significantly increasing heat generation, posing a greater challenge to heat dissipation.

[0004] Currently, the mainstream cooling methods for fixed charging piles are air cooling and liquid cooling. However, mobile charging piles are limited by vehicle space, weight, and independent energy supply, and cannot carry traditional large-scale compressor refrigeration units, making heat dissipation capacity a bottleneck. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a phase change cooling mobile supercharging device that utilizes cold storage technology to significantly reduce reliance on high-power real-time cooling during charging, thus solving the fundamental problem that mobile platforms cannot support large-scale cooling equipment.

[0006] The technical solution adopted by this invention to solve its technical problem is: A phase change cooling mobile supercharging device includes a charging unit and a mobile unit for supporting the charging unit. The charging unit includes a main housing, and the internal space of the main housing is divided into a first space and a second space from top to bottom by a first partition. A cold storage unit is installed in the second space, and a refrigeration unit and an energy storage unit are installed in the first space. The cold storage unit includes a cold storage box, which is equipped with several cold storage components. The cold storage components divide the internal space of the cold storage box into air-cooled channels. The cold storage box is equipped with a first air inlet and a first air outlet. The first air outlet is connected to the first space through a flexible hose. The cold storage component includes a shell and a cold storage coil. The shell is filled with a cold storage medium. The cold storage coils of two adjacent cold storage components are connected to form a continuous cold storage channel. Both ends of the cold storage channel extend to the outside of the cold storage box. An intake fan is provided at the first air inlet, and a first exhaust fan is provided at the first air outlet. The energy storage unit includes a battery module and a liquid cooling component for cooling the battery module; The inlet of the liquid cooling component and the inlet of the cold storage channel of the cold storage unit are connected to the outlet of the refrigeration unit through a first pipeline and a second pipeline, respectively. A first control valve is installed on the first pipeline, and a second control valve is installed on the second pipeline. The inlet of the refrigeration unit and the inlet of the cold storage channel of the cold storage unit are connected to the outlet of the liquid cooling component through a third pipeline and a fourth pipeline, respectively. A third control valve is installed on the third pipeline, and a fourth control valve is installed on the fourth pipeline. The outlet of the cold storage channel of the cold storage unit is connected to the inlet of the refrigeration unit through a fifth pipeline.

[0007] Furthermore, the liquid cooling component includes several liquid cooling plates, with a battery module disposed between two adjacent liquid cooling plates. The liquid cooling plates are provided with a serpentine liquid cooling channel, one end of which is connected to a first manifold and the other end of which is connected to a second manifold.

[0008] Furthermore, the liquid cooling plate includes several liquid cooling sub-plates, each with a through-channel. The sub-channels are connected by connecting pipes, and the sub-channels and connecting pipes together form a serpentine liquid cooling flow channel.

[0009] Furthermore, the liquid cooling sub-plates of several liquid cooling plates are aligned one by one, and the aligned liquid cooling sub-plates form a liquid cooling sub-plate group. The liquid cooling sub-plates in the liquid cooling sub-plate group are connected into a whole by several support columns. Several battery modules corresponding one-to-one with the liquid cooling sub-plates are arranged between two adjacent liquid cooling plates. The side of the battery module is provided with a recess for accommodating the support column.

[0010] Furthermore, the main housing includes a main frame and a cover. The main frame includes a top frame with a cuboid structure. A crossbar is provided on the lower side of the top frame. The rear end of the crossbar is fixedly connected to the top frame. A movable support frame for supporting the cold storage unit is provided inside the main housing between the top frame and the crossbar. The movable support frame is slidably connected to the main housing.

[0011] Furthermore, the movable support frame is a vertical frame, with its upper and lower ends slidably connected to the top frame and the cross frame, respectively. The movable support frame is provided with a support surface for supporting the rear end of the cold storage unit. The front end of the cross frame is provided with a first lifting slide for supporting the cold storage unit, and the front end of the lower side of the top frame is provided with a second lifting slide. The lower end of the second lifting slide abuts against the cold storage unit.

[0012] Furthermore, a locking mechanism is provided between the movable support frame and the cross frame. The locking mechanism includes a locking member located on the side of the movable support frame facing away from the cold storage unit. The locking member is slidably connected to the movable support frame vertically, and the locking member is provided with an inclined surface. The movable support frame is provided with a top column, which is slidably connected to the movable support frame front and back, and the top column abuts against the inclined surface. The cross frame is provided with a locking strip with a toothed structure at the top. In the free state, the locking member is located at the lower limit position, the lower end of the locking member is engaged in the toothed structure of the locking bar, and the end of the top column facing the cold storage unit is located on the upper side of the supporting surface. When the rear side of the cold storage unit is in contact with the movable support frame, the top column acts on the inclined surface under the pushing action of the cold storage unit, the locking member moves upward to the limit position, and the lower end of the locking member disengages from the locking strip.

[0013] Furthermore, an elastic element is provided between the locking member and the movable support frame to prevent the locking member from moving upward relative to the movable support frame.

[0014] Furthermore, support rollers are respectively provided on the left and right sides of the front end of the cross frame.

[0015] Furthermore, a positioning post is provided on the support surface of the first lifting slide, a positioning hole that cooperates with the positioning post is provided on the lower side of the cold storage box, a guide groove with an opening facing the side of the cold storage unit is provided on the supporting surface of the movable support frame, and a guide post that cooperates with the guide groove is provided on the lower side of the cold storage box.

[0016] The beneficial effects of this invention are: 1. The phase change cooling mobile supercharging equipment provided in this application embodiment, by adding a cold storage unit and using the cold storage unit for auxiliary cooling, can not only significantly reduce the dependence on large-scale refrigeration equipment with high power real-time cooling during the charging process, but also effectively reduce the power and volume of the refrigeration unit while ensuring heat dissipation effect, thus solving the fundamental problem that the mobile platform cannot support large-scale refrigeration equipment. Moreover, since the cold storage unit can provide a huge amount of cooling output in a short time, it can support mobile charging piles to carry out short-term "burst" supercharging at higher power (such as 600kW) to meet emergency needs.

[0017] 2. The phase change cooling mobile supercharging equipment provided in this application embodiment has different working modes and can adapt to different charging modes and ambient temperatures.

[0018] 3. The mobile supercharging equipment with phase change cooling provided in this application embodiment can use off-peak electricity at night for cold storage, which is not only low-cost and can effectively reduce operating energy consumption and costs, but also shifts the cooling load to off-peak hours at night, which helps the power grid to shave peaks and fill valleys.

[0019] 4. The mobile supercharging equipment with phase change cooling provided in this application embodiment uses a cold storage unit for auxiliary cooling, which can significantly reduce cooling power consumption during charging, thereby saving vehicle battery power and increasing service mileage and frequency.

[0020] 5. The mobile supercharging equipment with phase change cooling provided in this application embodiment has two cooling methods and the reliability of the cold storage unit. Therefore, compared with the traditional single cooling method, it can effectively improve the overall reliability of the equipment operation.

[0021] 6. The mobile supercharging equipment with phase change cooling provided in this application embodiment reduces the power of the cooling unit or operates intermittently during the charging process, which can reduce noise pollution. Attached Figure Description

Moving assembly. Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0026] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0027] like Figure 1As shown, a phase-change cooled mobile supercharging device includes a charging unit 1 and a movable unit 2 for supporting the charging unit 1. The charging unit 1 is detachably fixed to the movable unit 2.

[0028] The mobile assembly 2 can be an AGV (Automated Guided Vehicle), a commercial vehicle chassis, or a regular mobile chassis. An AGV, also known as an AGV intelligent handling robot, is an intelligent logistics device based on automatic navigation technology. A commercial vehicle chassis refers to a type II chassis that includes a cab, engine, transmission system, etc., but does not include a cargo box. This type of chassis can be directly used to modify special-purpose vehicles (such as trucks and engineering vehicles). A regular mobile chassis refers to a frame that only has rollers or wheels installed, and this frame needs to be moved manually or by a towing vehicle. Whether it is an AGV, a commercial vehicle chassis, or a regular mobile chassis, all are existing technologies, and their specific structures will not be described in detail here. As a specific implementation, the mobile assembly 2 in this embodiment uses an AGV.

[0029] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the charging unit 1 includes a main housing, and a first partition is provided inside the main housing, which divides the internal space of the main housing into a first space and a second space from top to bottom. A second partition 115 is provided inside the first space, and the second partition 115 divides the second space into a first subspace and a second subspace along the horizontal direction.

[0030] The second space is equipped with a cold storage unit 12, the first subspace is equipped with a refrigeration unit 13 and a control unit (not shown in the figure), and the second subspace is equipped with an energy storage unit 14.

[0031] Furthermore, a third partition 116 is provided within the first subspace, which divides the first subspace into upper and lower parts, wherein the refrigeration unit 13 is located in the upper part and the control unit is located in the lower part.

[0032] like Figure 12 , Figure 14 , Figure 15 and Figure 16 As shown, the cold storage unit 12 includes a cold storage box, which includes an insulated box body 121 made of insulation material. A plurality of cold storage components 122 are arranged inside the insulated box body 121 along one direction. As a specific embodiment, in this embodiment, the insulated box body 121 has components arranged along its length (according to...) Figure 1The components are evenly arranged (the coordinate system shown is in the left-right direction). The lower side of the cold storage component 122 is in contact with the bottom surface of the internal space of the insulation box 121, and the upper side of the cold storage component 122 is in contact with the top surface of the internal space of the insulation box 121. The cold storage component 122 divides the internal space of the insulation box 121 into a serpentine structure of air-cooling channels. As a specific embodiment, in this embodiment, five cold storage components 122 are evenly distributed laterally inside the insulation box 121. In order from left to right, the rear sides of the 1st, 3rd, and 5th cold storage components 122 are in contact with the rear side of the internal space of the insulation box 121, and the front sides of the 2nd and 4th cold storage components 122 are in contact with the front side of the internal space of the insulation box 121. A first air inlet is provided at one end of the air-cooling channel on the cold storage box, and a first air outlet is provided at the other end of the air-cooling channel on the cold storage box. The first partition is provided with a second air inlet 1141, and the first air outlet is connected to the second air inlet 1141 via a flexible hose (not shown in the figure). One end of the hose is detachably fixed to the cold storage box. Preferably, the other end of the hose is detachably connected to the first partition, and the hose is an accordion hose. This way, when the cold storage unit 12 is located in the main box, although the hose is in a folded state, the pipeline can still be kept straight and will not bend, thereby reducing the resistance to airflow during air cooling.

[0033] In one specific embodiment, the insulated box 121 in this embodiment includes an insulated box body 1211 and an upper cover 1212, wherein the upper cover 1212 is fixedly connected to the insulated box body 1211 by screws.

[0034] The cold storage component 122 includes a housing and a cold storage coil 1224 disposed within the housing. Both ends of the cold storage coil 1224 extend through the housing to the outside of the housing. The housing has through holes allowing the cold storage coil 1224 to pass through. The end of the cold storage coil 1224 passes through the through holes and is sealed to the housing. The housing is filled with a cold storage medium, and the middle portion of the cold storage coil 1224 is embedded within the cold storage medium. Preferably, the cold storage medium is made of a phase change material.

[0035] The cold storage coils 1224 of two adjacent cold storage components 122 are connected by connectors. A plurality of the cold storage coils 1224 of the cold storage components 122 form a continuous cold storage channel, and both ends of the cold storage channel extend through the insulation box 121 to the outside of the insulation box 121. In one specific embodiment, the cold storage coils 1224 of two adjacent cold storage components 122 are connected by pipe joints.

[0036] In one specific embodiment, the end of the cold storage coil 1224 passes through the through hole and is fixedly connected to the housing by welding. The housing includes an outer shell body 1221 and a cover plate 1222. The cover plate 1222 is connected and fixed to the outer shell body 1221 by screws, and a sealing gasket 1223 is provided between the cover plate 1222 and the outer shell body 1221.

[0037] In one specific embodiment, the cold storage coil 1224 described in this embodiment includes a heat exchange section with a serpentine structure, and a first connecting section and a second connecting section located at both ends of the heat exchange section, with the first connecting section and the second connecting section respectively located at both ends of the shell. The cold storage coils 1224 of several cold storage components 122 have similar shapes, differing in that: in order from left to right, the first connecting section of the cold storage coil 1224 of the first cold storage component 122 extends in the front-back direction and passes through the front sidewall of the shell and the insulation box 121 sequentially to the outside of the insulation box 121; the second connecting section of the cold storage coil 1224 of the first cold storage component 122 extends in the left-right direction and passes through the sidewall of the shell to the right to the outside of the shell; the cold storage coil of the second cold storage component 122... The first connecting section of the coil 1224 extends in the front-rear direction, passes rearward through the side wall of the housing, and connects to the second connecting section of the cold storage coil 1224 of the first cold storage component 122 via a pipe joint. The second connecting section of the cold storage coil 1224 of the second cold storage component 122 extends in the left-right direction, passes to the right through the side wall of the housing, and extends to the outside of the housing. The first connecting section of the cold storage coil 1224 of the third cold storage component 122 extends in the front-rear direction, passes forward through the side wall of the housing, and connects to the second cold storage component 1224 via a pipe joint. The second connecting section of the cold storage coil 1224 of the third cold storage component 122 is connected to the second connecting section of the cold storage coil 1224 of the fourth cold storage component 122. The second connecting section of the cold storage coil 1224 of the fourth cold storage component 122 extends in the left-right direction and passes through the side wall of the housing to the outside of the housing. The first connecting section of the cold storage coil 1224 of the fourth cold storage component 122 extends in the front-back direction and passes through the side wall of the housing to the rear, and then connects to the second connecting section of the cold storage coil 1224 of the third cold storage component 122 through a pipe joint. The second connecting section of the cold storage coil 1224 of the fourth cold storage component 122 extends in the front-back direction and passes through the side wall of the housing to the rear, and then connects to the second connecting section of the cold storage coil 1224 of the third cold storage component 122 through a pipe joint. The first connecting section of the cold storage coil 1224 of the fifth cold storage component 122 extends in the front-back direction, passes forward through the side wall of the housing, and then connects to the second connecting section of the cold storage coil 1224 of the fourth cold storage component 122 through a pipe joint. The second connecting section of the cold storage coil 1224 of the fifth cold storage component 122 extends in the front-back direction, passes forward through the front side wall of the housing and the insulation box 121 in sequence, and extends to the outside of the insulation box 121.

[0038] Furthermore, an intake fan 123 is provided at the first air inlet, and a first exhaust fan 124 is provided at the first air outlet. A second air outlet communicating with the second subspace is provided on the main housing, and a second exhaust fan 118 is provided on the second air outlet.

[0039] Furthermore, the cold storage box also includes an external frame 125 made of high-strength metal material disposed outside the insulated box body 121.

[0040] In one specific embodiment, the external frame 125 in this example includes a lower frame formed by four angle steels connected end to end in sequence. Above the lower frame is an upper frame formed by four angle steels connected end to end in sequence. Four connecting angle steels are respectively provided at the four corners between the upper and lower frames. The openings of the angle steels forming the external frame 125 all face the insulation box 121 and cover the outside of the edges of the insulation box 121. This effectively improves the structural strength of the entire cold storage unit 12.

[0041] like Figure 18 and Figure 19 As shown, the energy storage unit 14 includes a liquid cooling component and a battery module 147.

[0042] The liquid cooling component includes several liquid cooling plates arranged vertically, with a battery module 147 disposed between two adjacent liquid cooling plates. Each liquid cooling plate contains a serpentine liquid cooling channel. The energy storage unit 14 also includes a first manifold 144 and a second manifold 145. The first manifold 144 has a first liquid inlet 1441 (i.e., the inlet of the liquid cooling component) and several first liquid outlets 1442 corresponding to each of the liquid cooling plates. The second manifold 145 has a second liquid outlet 1451 (i.e., the outlet of the liquid cooling component) and several second liquid inlets 1452 corresponding to each of the liquid cooling plates. One end of the liquid cooling channels of the plurality of liquid cooling plates is connected to the corresponding first liquid outlet 1442 on the first manifold 144 via a connector (e.g., a pipe joint), and the other end of the liquid cooling channels of the plurality of liquid cooling plates is connected to the corresponding first liquid inlet 1441 on the second manifold 145 via a connector (e.g., a pipe joint).

[0043] like Figure 23As shown, the first liquid inlet 1441 on the first manifold 144 and the inlet of the cold storage channel of the cold storage unit 12 are respectively connected to the outlet of the refrigeration unit 13 through the first pipeline 15 and the second pipeline 152. A first control valve 1511 for controlling the on / off state of the first pipeline 15 is provided on the first pipeline 15, and a second control valve 1521 for controlling the on / off state of the second pipeline 152 is provided on the second pipeline 152. The inlet of the refrigeration unit 13 and the inlet of the cold storage channel of the cold storage unit 12 are respectively connected to the second liquid outlet 1451 on the second manifold 145 through the third pipeline 153 and the fourth pipeline 154. A third control valve 1531 for controlling the on / off state of the third pipeline 153 is provided on the third pipeline 153, and a fourth control valve 1541 for controlling the on / off state of the fourth pipeline 154 is provided on the fourth pipeline 154. The outlet of the cold storage channel of the cold storage unit 12 is connected to the inlet of the refrigeration unit 13 through the fifth pipeline 155.

[0044] The advantage of this design is that, in cold storage mode, the first, third, and fourth control valves are closed, and the second control valve 1521 is open. At this time, the refrigerant in the refrigeration unit 13 transfers cooling capacity to the cold storage medium only through the cold storage channel of the cold storage unit 12, thus achieving cold storage using the refrigeration unit 13 itself. In operation, multiple different operating modes can be provided to cope with different application scenarios, as detailed below: First, only the intake fan 123, the first exhaust fan 124, and the second exhaust fan 118 are turned on, i.e., heat dissipation and cooling are achieved through air cooling. Second, the second and fourth valves are closed, and the first and third valves are opened, allowing the battery module 147 to be cooled through contact with the liquid cooling plate. Third, the second and third valves are closed, and the first and fourth valves are opened. In this case, the refrigerant that has undergone heat exchange first passes through the cold storage unit 12 for pre-cooling, thereby reducing the temperature of the refrigerant, before entering the refrigeration unit 13 for cooling, which can effectively reduce the power of the refrigeration unit 13. Fourth, air cooling is added to the second and third operating modes respectively, thereby further improving the heat dissipation effect.

[0045] Furthermore, each of the liquid cooling plates includes several liquid cooling sub-plates 141, and several parallel sub-channels 1411 are provided through the liquid cooling sub-plates 141. The sub-channels 1411 are connected by connecting pipes, and the sub-channels 1411 and the connecting pipes together form a serpentine liquid cooling flow channel.

[0046] In one specific implementation, the energy storage unit 14 described in this embodiment includes six liquid-cooled plates. Each liquid-cooled plate includes two liquid-cooled sub-plates 141, and each liquid-cooled sub-plate 141 is provided with eight horizontally spaced... Figure 1The coordinate system shown is used to describe the sub-channels 1411 that pass through the liquid-cooled subplate 141. The eight sub-channels 1411 of two liquid-cooled subplates 141 of the same liquid-cooled plate are aligned one-to-one, and two aligned sub-channels 1411 are connected by a first connecting pipe 142. In order from back to front, the liquid-cooled subplate 141 on the right side: the right end opening of the first sub-channel 1411 is connected to the right end opening of the second sub-channel 1411 via a second connecting pipe 143; the right end opening of the third sub-channel 1411 is connected to the right end opening of the fourth sub-channel 1411 via a second connecting pipe 143; the right end opening of the fifth sub-channel 1411 is connected to the right end opening of the sixth sub-channel 1411 via a second connecting pipe 143; the right end opening of the seventh sub-channel 1411 is connected to the right end opening of the eighth sub-channel 1411 via a second connecting pipe 143; the liquid-cooled subplate 141 on the left side: the first sub-channel 1411... The left end opening of 411 is connected to the corresponding first outlet 1442 on the first manifold 144 via a connector. The left end opening of the second sub-channel 1411 is connected to the left end opening of the third sub-channel 1411 via a second connecting pipe 143. The left end opening of the fourth sub-channel 1411 is connected to the left end opening of the fifth sub-channel 1411 via a second connecting pipe 143. The left end opening of the sixth sub-channel 1411 is connected to the right end opening of the seventh sub-channel 1411 via a second connecting pipe 143. The left end opening of the eighth sub-channel 1411 is connected to the corresponding first inlet 1441 on the second manifold 145 via a connector.

[0047] Furthermore, the liquid cooling sub-plates 141 of the plurality of liquid cooling plates are aligned one-to-one, that is, the liquid cooling sub-plates 141 on the left side are aligned vertically, and the liquid cooling sub-plates 141 on the right side are aligned vertically. The mutually aligned liquid cooling sub-plates 141 form a group of liquid cooling sub-plates 141, and the liquid cooling sub-plates 141 in the same group of liquid cooling sub-plates 141 are connected into a whole by a plurality of support columns 146. The support column 146 includes a base plate, which is fixedly connected to the first partition by means of screws or the like in a detachable manner. The base plate is provided with a column with a stepped shaft structure, which includes a first shaft segment and a second shaft segment from bottom to top, and the diameter of the first shaft segment is larger than the diameter of the second shaft segment. The second shaft segment of the column passes through the liquid cooling sub-plates 141 upwards, and the liquid cooling sub-plates 141 are provided with connecting holes for accommodating the second shaft segment. The diameter of the connecting holes is equal to the diameter of the second shaft segment and forms a clearance fit. A locking nut 1461 is provided above the uppermost liquid cooling subplate 141 on the column. Under the locking action of the locking nut 1461, the battery module 147 is pressed between the adjacent liquid cooling plates, thereby making close contact with the liquid cooling plates and improving the heat dissipation effect.

[0048] In one specific implementation, in this embodiment, the liquid cooling subplates 141 in the same group of liquid cooling subplates 141 are connected into a whole by four support columns 146. The liquid cooling subplate 141 has a square structure, and the connecting holes that cooperate with the connecting columns are located at the four corners of the liquid cooling subplate 141 and are staggered with the sub-channels 1411 in the liquid cooling subplate 141, that is, the connecting holes are not connected to the sub-channels 1411.

[0049] Furthermore, a plurality of battery modules 147 are disposed between two adjacent liquid cooling plates, and the battery modules 147 correspond one-to-one with the liquid cooling sub-plates 141 of the liquid cooling plates.

[0050] Furthermore, such as Figure 17 As shown, the side of the battery module 147 is provided with a recess 1471 for accommodating the support column 146. In one specific embodiment, the front and rear sides of the battery module 147 are respectively provided with recesses 1471 that mate with the second shaft segment of the support column 146.

[0051] By providing the recessed portion 1471, the battery module 147 can be locked and fixed, thereby preventing the position of the battery module 147 from changing.

[0052] Furthermore, the main housing is provided with an opening to facilitate the removal of the cold storage unit 12 from the main housing. In one specific embodiment, the opening is located on the front side of the main housing.

[0053] Furthermore, in order to facilitate the removal of the cold storage unit 12 from the main housing, a movable support frame 16 for supporting the cold storage unit 12 is provided in the main housing, and the movable support frame 16 is slidably connected to the main housing.

[0054] Furthermore, the main housing includes a main frame and a cover. The main frame includes a top frame 111 with a cuboid structure, and a crossbeam 112 is provided on the lower side of the top frame 111. The distance between the crossbeam 112 and the top frame 111 is greater than the height of the cold storage unit 12, and the rear end of the crossbeam 112 is fixedly connected to the top frame 111.

[0055] Here, the horizontal frame 112 can be connected and fixed to the top frame 111 via a separate upright frame 113, or the rear side of the top frame 111 can extend downwards and be fixedly connected to the horizontal frame 112 by welding. In one specific embodiment, an upright frame 113 is provided between the horizontal frame 112 and the top frame 111. The lower end of the upright frame 113 is fixedly connected to the rear end of the horizontal frame 112 by welding, and the upper end of the upright frame 113 is fixedly connected to the rear end of the lower side of the top frame 111 by welding.

[0056] A base plate 114 is provided inside the top frame 111 above the bottom frame. The base plate 114 is fixedly connected to the bottom frame by screws or other detachable means. The base plate 114 and the bottom frame together form the ground partition.

[0057] The housing includes a fixed portion 1171 and a detachable portion 1172.

[0058] The fixed portion 1171 includes a top plate, and side plates extending downwards perpendicularly to the top plate are respectively provided around the top plate. According to their orientation, the side plates include a front side plate, a rear side plate, a left side plate, and a right side plate, wherein the rear side plate extends downwards to the lower side of the crossbeam 112, and the front side plate, left side plate, and right side plate extend downwards to the lower side of the top frame 111. The top plate and side plates together form a box structure with an opening facing downwards. The fixed portion 1171 covers the outside of the main frame from top to bottom and is fixedly connected to the main frame by screws or other detachable means. A door is provided on the front side plate; when the door is opened, the second subspace is in an open state.

[0059] The detachable portion 1172 includes a web plate, with wing plates extending rearward perpendicularly to the web plate at both ends. The web plate and wing plates together form a U-shaped structure with an opening facing rearward. The lower end of the web plate is detachably connected to the front side of the cross frame 112 by screws or other means. The lower ends of the two wing plates are detachably connected to the left and right sides of the cross frame 112 by screws or other means, respectively. The rear ends of the two wing plates are detachably connected to the left and right sides of the upright frame 113 by screws or other means, respectively.

[0060] The lower end of the main frame is generally C-shaped with an opening facing forward, and the cold storage unit 12 is located within the C-shaped structure. While this increases the installation space for the cold storage unit 12 and maximizes its volume without hindering its removal, thus increasing the cold storage capacity, the lack of front support between the top frame 111 and the crossbeam 112 severely affects the structural rigidity and strength of the entire main frame.

[0061] To solve this problem, such as Figure 3 , Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, the movable support frame 16 is a vertical frame. The upper end of the movable support frame 16 is slidably connected to the first partition via a sliding component, and the lower end of the movable support frame 16 is slidably connected to the cross frame 112 via a sliding component. The lower end of the movable support frame 16 is provided with a support surface for supporting the rear end of the cold storage unit 12. A first lifting slide 171 for supporting the cold storage unit 12 is provided at the front end of the cross frame 112, and a second lifting slide 172 is provided at the front end of the lower side of the top frame 111. The upper end of the second lifting slide 172 is fixedly connected to the top frame 111 by screws or other detachable means, and the lower end of the second lifting slide 172 abuts against the outer frame 125 of the cold storage unit 12.

[0062] The first lifting slide 171 and the second lifting slide 172 can be electrically adjustable or manually adjustable, and both can be obtained by direct purchase. As a specific embodiment, in this example, both the first lifting slide 171 and the second lifting slide 172 are manually adjustable.

[0063] In one specific embodiment, the movable support frame 16 in this embodiment includes a lower crossbeam 161 and an upper crossbeam 162, which are angle steel structures. A plurality of connecting beams 163 are evenly distributed along the length of the upper crossbeam 162 and the lower crossbeam 161. The upper ends of the connecting beams 163 are welded to the outer surface of the vertical portion of the upper crossbeam 162 (according to...). Figure 1 The coordinate system shown is the rear side of the vertical part. The lower end of the connecting beam 163 is welded to the outer side of the vertical part of the lower crossbeam 161 (according to the coordinate system shown). Figure 1 The coordinate system shown is used for the fixed connection of the rear side of the vertical part. The upper side of the horizontal part of the lower crossbeam 161 is the supporting surface.

[0064] In one specific implementation, the sliding component described in this embodiment employs a linear guide rail pair. First guide rails 1121 are respectively provided at the left and right ends of the upper side of the crossbeam 112, and first sliders 1611 cooperating with the first guide rails 1121 are respectively provided at the left and right ends of the lower side of the crossbeam 161. Second guide rails 1111 are respectively provided at the left and right ends of the lower side of the top frame 111, and second sliders 1621 cooperating with the second guide rails 1111 are respectively provided at the left and right ends of the lower side of the upper crossbeam 162.

[0065] Furthermore, in order to ensure that the movable support is located on the front side of the main frame when the cold storage unit 12 is moved out, thereby forming a reliable support for the open end of the C structure, a locking mechanism 18 is provided between the movable support frame 16 and the cross frame 112.

[0066] like Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the locking mechanism 18 includes a locking member located on the side of the movable support frame 16 facing away from the cold storage unit 12. The locking member is slidably connected to the movable support frame 16 vertically, and the locking member has an inclined surface 1814. A top post 182 is provided on the upper side of the supporting surface of the movable support frame 16. The top post 182 is slidably connected to the movable support frame 16 front and back, and the end of the top post 182 facing the locking member abuts against the inclined surface 1814. A locking strip 183 is provided on the cross frame 112 directly below the locking member, and the upper side of the locking strip 183 has a toothed structure that cooperates with the locking member. In its free state, the locking member moves downward to its limit position under the action of gravity, and the lower end of the locking member engages with the toothed structure of the locking strip 183 to achieve locking. The top column 182 moves towards the side closer to the cold storage unit 12 under the pushing action of the inclined surface 1814, and the end of the top column 182 facing the cold storage unit 12 is located on the upper side of the supporting surface. When the rear end of the cold storage unit 12 is placed on the supporting surface of the movable support frame 16, and the rear side of the cold storage unit 12 is in contact with the side of the movable support frame 16 facing the cold storage unit 12, the top column 182 moves away from the cold storage unit 12 under the pushing action of the cold storage unit 12. At the same time, through the interaction of the top column 182 and the inclined surface 1814, the locking member moves upward to its limit position, and the lower end of the locking member disengages from the locking strip 183. At this time, the movable support frame 16 can move back and forth relative to the main frame.

[0067] In one specific embodiment, the locking component in this example includes, from top to bottom, a driving block 1811 and a locking block 1812. Two guide slide rods 1813 are disposed between the driving block 1811 and the locking block 1812. The lower end of each guide slide rod 1813 is fixedly connected to the locking block 1812 by welding, and the upper end of each guide slide rod 1813 is detachably fixedly connected to the driving block 1811. An inclined surface 1814 is disposed on the driving block 1811 and located between the two guide slide rods 1813. Two ear plates 1612 are disposed on the rear side of the vertical portion of the lower crossbeam 161 of the movable support frame 16. Each ear plate 1612 has a guide hole that mates with the guide post.

[0068] In one specific implementation, two sets of locking mechanisms 18 are provided between the movable support frame 16 and the cross frame 112 in this embodiment.

[0069] Furthermore, an elastic element is provided between the locking member and the movable support frame 16 to prevent the locking member from moving upward relative to the movable support frame 16.

[0070] In one specific embodiment, the elastic element is a spring 184 sleeved on the guide slide 1813. The upper end of the spring 184 abuts against the ear plate 1612, and the lower end of the spring 184 abuts against the locking block 1812.

[0071] Furthermore, support rollers 19 are respectively provided on the left and right sides of the front end of the cross frame 112. In one specific embodiment, the support rollers 19 are located on the rear side of the first lifting slide 171.

[0072] Furthermore, such as Figure 11 and Figure 13 As shown, a positioning post 1711 is provided on the support surface of the first lifting slide 171, and a positioning hole 1251 that mates with the positioning post 1711 is provided on the lower side of the cold storage box. For example, two positioning posts 1711 are provided on the support surface of the first lifting slide 171.

[0073] By setting the positioning post 1711, the cold storage unit 12 can be fixed, and the position of the cold storage unit 12 can be prevented from moving due to inertia and other factors during the movement.

[0074] Furthermore, to facilitate the installation of the cold storage unit 12, such as Figure 9 , Figure 10 and Figure 12As shown, the supporting surface of the movable support frame 16 is provided with a guide groove 1613 with an opening facing the cold storage unit 12, and the lower side of the cold storage box is provided with a guide post 1252 that cooperates with the guide groove 1613.

[0075] In one specific embodiment, the guide grooves 1613 described in this example are disposed on the horizontal portion of the lower crossbeam 161, and there are two of them. Correspondingly, the rear end of the lower side of the cold storage box is provided with two guide posts 1252 that correspond one-to-one with the guide grooves 1613. The guide posts 1252 are fixedly connected to the lower frame of the external frame 125 of the cold storage box by means of threaded connection. The opening end of the guide groove 1613 has a trumpet-shaped structure.

[0076] When disassembling the cold storage unit 12, firstly, remove the disassembly part 1172 of the cover, and adjust the second lifting slide 172 so that the support surface of the second lifting slide 172 is disengaged from the cold storage box, and then proceed as follows: Figure 20 As shown, adjust the first lifting slide 171 until the positioning column 1711 is completely disengaged from the cold storage box. Then proceed as follows: Figure 21 As shown, drag outwards (according to...) Figure 1 The coordinate system shown is for dragging the cold storage unit 12 forward. After the cold storage unit 12 is moved to a suitable position (usually less than 1 / 2 of the width of the cold storage box), the hose is removed from the cold storage box. Then continue dragging the cold storage unit 12 outward until the moving support frame 16 abuts against the bracket of the supporting roller 19 (since the locking part is in the raised state at this time, the moving support frame 16 can slide relative to the main frame). Then continue dragging the cold storage unit 12 outward. At this time, because the moving support frame 16 cannot move forward further due to the obstruction of the supporting roller 19, therefore... Figure 22 The cold storage unit 12 shown will move forward relative to the movable support frame 16. At this time, the top column 182 is not restricted by the cold storage unit 12 and can move forward. Therefore, the locking member will move downward under the elastic action of the spring 184, thereby engaging the locking bar 183 and achieving locking.

[0077] When installing the cold storage unit 12, first insert the rear end of the cold storage unit 12 into the opening end of the C-shaped structure of the main frame, and make the lower side of the rear end of the cold storage unit 12 abut against the supporting roller 19. Then push the cold storage unit 12 backward, and achieve lateral installation positioning under the guidance of the guide post 1252 and the guide groove 1613. Since the locking mechanism 18 is in the locked state at this time, the movable support frame 16 is fixed. At this time, even if there is sliding friction between the cold storage unit 12 and the movable support frame 16, the movable support frame 16 will not move until the rear side of the cold storage unit 12 is in contact with the rear side of the movable support frame 16. When the rear side of the cold storage unit 12 is in contact with the rear side of the movable support frame 16, the locking state of the movable support frame 16 is released. At this time, continue to push the cold storage unit 12 backward, and the movable support frame 16 and the cold storage unit 12 can move backward together. After the cold storage unit 12 has moved backward to a suitable position (usually more than 1 / 2 the width of the cold storage box), connect the hose to the first air outlet of the cold storage box. Then continue to push the cold storage unit 12 backward until the positioning hole 1251 on the cold storage box is aligned with the positioning post 1711 on the first lifting slide 171. Then adjust the first lifting slide 171 and the second lifting slide 172 respectively so that their supporting surfaces abut against the cold storage box.
