[0049] Figure 1 Fig. 1 is a structural schematic diagram of a mobile cold storage device in the embodiment, Figure 2 Fig. 2 is a flow structural schematic diagram of the mobile cold storage device in the embodiment.

[0050] Reference Figure 1 and Figure 2 In the embodiment, the mobile cold storage device comprises a shell 1, a heat exchange module 2 and a pipeline assembly 3. The heat exchange module 2 is arranged in the shell 1, and the heat exchange module 2 comprises a shell body 21 and a heat exchange assembly 22 and a cold storage agent arranged in the shell body 21. The heat exchange assembly 22 has an inlet and an outlet, and the inlet and the outlet of the heat exchange assembly 22 are used for communicating with an external device for supplying a cold carrier. The heat exchange assembly 22 is internally used for circulating the cold carrier. When the temperature of the cold carrier entering the heat exchange assembly 22 is lower than the eutectic point temperature of the cold storage agent, the cold storage agent in the heat exchange assembly 22 can absorb the cold quantity of the cold carrier to reduce the temperature below the eutectic point to completely solidify to achieve the charging cold; when the temperature of the cold carrier entering the heat exchange assembly 22 is higher than the eutectic point temperature of the cold storage agent, the cold storage agent can absorb the heat of the cold carrier to increase the temperature above the eutectic point to completely melt to achieve the discharging cold. The pipeline assembly 3 can be accommodated in the shell 1, and the pipeline assembly 3 comprises a first connecting part 31 and a second connecting part 32. The first connecting part 31 communicates with the inlet of each heat exchange assembly 22, and the first connecting part 31 is used for communicating with and detachably connecting with the external device for supplying the cold carrier or the device to be charged cold. The second connecting part 32 communicates with the outlet of each heat exchange assembly 22, and the second connecting part 32 is used for communicating with and detachably connecting with the external device for supplying the cold carrier or the device to be charged cold.

[0051] In the application, the inlet of the heat exchange assembly 22 of the heat exchange module 2 is communicated with the external device for supplying the cold carrier or the device to be charged cold by detachable connection of the first connecting part 31 with the external device for supplying the cold carrier or the device to be charged cold. Similarly, the outlet of the heat exchange assembly 22 of the heat exchange module 2 is communicated with the external device for supplying the cold carrier or the device to be charged cold by detachable connection of the second connecting part 32 with the external device for supplying the cold carrier or the device to be charged cold.

[0052] That is, by the above-mentioned manner, the inlet and outlet of the heat exchange assembly 22 of the heat exchange module 2 and the device for supplying the coolant outside form a loop for the coolant to flow, and when the temperature of the coolant entering the heat exchange assembly 22 is lower than the eutectic point temperature of the cold storage agent, and in the process of circulating the coolant in the loop, the cold energy obtained by the coolant in the device for supplying the coolant outside can be continuously transferred to the heat exchange assembly 22 of the heat exchange module 2, so that the cold storage agent absorbs the cold energy and solidifies completely below the eutectic point to achieve the charging of cold. Alternatively, by the above-mentioned manner, the inlet and outlet of the heat exchange assembly 22 of the heat exchange module 2 and the device to be charged outside form a loop for the coolant to flow, and in the process of circulating the coolant in the loop, the cold energy obtained by the heat exchange between the coolant and the cold storage agent can be continuously transferred to the device to be charged outside, so that the solidified cold storage agent absorbs the heat and melts completely above the eutectic point to achieve the discharging of cold.

[0053] In short, the mobile cold storage device in the present application can transfer the cold energy obtained by the heat exchange between the mobile cold storage device and the device for supplying the coolant outside to the device to be charged, so as to realize the recycling of cold energy, and the mobile cold storage device can be transferred to supply cold to the device to be charged in a different place, so as to efficiently utilize the cold energy of LNG and improve economic benefits.

[0054] In addition, the first connecting component 31 and the second connecting component 32 are connected to the device for supplying the coolant outside or the device to be charged in a detachable manner, so as to realize the quick connection or quick disconnection between the mobile cold storage device and the device for supplying the coolant outside or the device to be charged, and the operation is convenient and simple.

[0055] In addition, the pipeline assembly 3 that is not used can be accommodated in the shell 1, so as to play the role of storage and protection for the pipeline assembly 3.

[0056] In the above, the device for supplying the coolant outside can be a cold taking device in an LNG gasification station, that is, the coolant absorbs the cold energy released in the LNG gasification and exchanges heat with the cold storage agent of the heat exchange module 2 to cool and solidify the cold storage agent, so as to store the cold energy in the heat exchange module 2. In the above, the device to be charged outside can be a cold storage room, a refrigerated vehicle or any structure that needs to keep low temperature by cold energy. That is, by the mobile cold storage device in the present embodiment as an intermediary, the recycling of cold energy in the LNG gasification station can be realized, and the cold energy stored in the mobile cold storage device can be transferred by transferring the mobile cold storage device, so as to conveniently meet the cooling demand of the cold storage room, the refrigerated vehicle and the like that are different from the LNG gasification station, so as to efficiently utilize the cold energy of LNG and improve economic benefits.

[0057] Reference Figure 1In the embodiment, the shell 1 is cuboid, and has three directions of length, width and height. For the convenience of description, the length direction of the shell 1 is defined as the longitudinal direction, the width direction of the shell 1 is defined as the transverse direction, and the height direction of the shell 1 is defined as the vertical direction. For example, the shell 1 can be a container.

[0058] The shell 1 is hollow. In the embodiment, the shell 1 is provided with a partition plate 11, the outer periphery of the partition plate 11 is fixed to the inner peripheral wall of the shell 1, and the partition plate 11 divides the internal space of the shell 1 into two independent accommodation cavities 12. Specifically, the partition plate 11 extends in the transverse direction, and the two accommodation cavities 12 divided by the partition plate 11 are distributed in the longitudinal direction.

[0059] For example, the shell 1 includes a box body and a box door. The box body is provided with an opening which communicates with the interior of the box body, and the opening can be one, two or more. When the opening is one, the opening is located at the partition plate 11, so that the opening communicates with the two accommodation cavities 12 at the same time. When the opening is two or more, each accommodation cavity 12 communicates with at least one opening. In this way, the staff can enter the interior of the box body through the opening of the box body, so as to perform maintenance, cleaning and other work on the structure in the interior of the box body.

[0060] The box door is arranged at the opening of the box body and is rotatably connected or detachably connected with the box body, so as to open and close the opening of the box body. At least one box door is arranged at each opening.

[0061] In other embodiments, the shell 1 can also be formed by connecting two independent box bodies.

[0062] Reference Figure 1 and Figure 2 The heat exchange module 2 is arranged in the shell 1. Specifically, the heat exchange module 2 is arranged in one of the accommodation cavities 12 of the shell 1.

[0063] The heat exchange module 2 includes a shell 21 and a heat exchange assembly 22 and a cold storage agent arranged in the shell 21.

[0064] The shell 21 is hollow, and the shell 21 is used for storing the cold storage agent.

[0065] Specifically, when the cold storage agent is below the phase change temperature, the cold storage agent solidifies, and when the temperature of the cold storage agent is higher than the phase change temperature, the cold storage agent melts. A large amount of heat needs to be absorbed or released when the cold storage agent changes phase, so as to store or release cold energy.

[0066] Specifically, the cold storage agent is a water solution of inorganic salt, which has a low freezing temperature and can adjust the freezing point of the cold storage agent by adjusting the concentration of the inorganic salt, so that the cold storage agent can also remain in a liquid state in a low-temperature environment to facilitate effective cold transfer in the low-temperature environment. In addition, compared with organic cold storage agents, inorganic salt cold storage agents have higher stability and safety and are less likely to explode. In addition, inorganic salt cold storage agents do not contain organic matter and have less environmental pollution. At the same time, inorganic salt cold storage agents have a large specific heat and excellent heat conduction performance, which can quickly and effectively transfer heat and improve the cold storage efficiency.

[0067] Exemplarily, the cold storage agent can be a water solution of inorganic salt such as magnesium chloride, sodium chloride, potassium chloride or calcium chloride.

[0068] In this embodiment, the shell 21 is in the shape of a rectangular parallelepiped and is arranged inside the shell 1 in a state that the length, width and height directions of the shell 21 are consistent with the length, width and height directions of the shell 1.

[0069] The shell 21 is made of carbon steel, stainless steel or aluminum.

[0070] In this embodiment, the shell 21 includes a shell body 211 and a cover 212. The shell body 211 is hollow inside and has an open top, and the cover 212 is detachably connected to the top of the shell body 211 to open and close the open top of the shell body 211.

[0071] The shell 21 is provided with an inlet 213 and an outlet 214. Specifically, the cover 212 is provided with the inlet 213 through which the cold storage agent can be injected into the shell 21. The bottom of the shell body 211 is provided with the outlet 214 through which the cold storage agent in the shell 21 can be discharged.

[0072] In this embodiment, the number of heat exchange assemblies 22 can be multiple, and the multiple heat exchange assemblies 22 are arranged at intervals in the shell 21. Specifically, the multiple heat exchange assemblies 22 are arranged at intervals in the transverse direction.

[0073] In this embodiment, each heat exchange assembly 22 is detachably connected to the shell 21. Exemplarily, the heat exchange module 2 further includes a mounting rack arranged inside the shell 21, and the mounting rack is provided with multiple mounting slots at intervals, and each mounting slot is in clamping cooperation with a heat exchange assembly 22. The mounting rack and the heat exchange assembly 22 can also be screwed by fasteners to reinforce the connection strength of the heat exchange assembly 22 and the mounting rack and improve the stability of the heat exchange assembly 22.

[0074] Figure 3 Fig. 2 is a flow structure diagram of the heat exchange module 2 in this embodiment, Figure 4 Fig. 3 is a structure diagram of the heat exchange assembly 22 in this embodiment, Figure 5 Fig. 4 is a side view of the heat exchange assembly 22 in this embodiment.

[0075] Reference Figures 1 to 5 The inlet and outlet of each heat exchange assembly 22 are used to communicate with the device supplying the secondary refrigerant or the device to be charged, and the heat exchange assembly 22 is used to flow the secondary refrigerant to cool or heat the regenerator to realize the charging or discharging of the heat exchange module 2.

[0076] In the embodiment, each heat exchange assembly 22 comprises a plurality of heat exchange pipes 221 and a plurality of heat exchange fins 222. The plurality of heat exchange fins 222 are arranged at intervals, and the plurality of heat exchange pipes 221 are arranged at intervals and pass through the plurality of heat exchange fins 222. Each heat exchange pipe 221 has an inlet and an outlet, and the inlet and outlet of each heat exchange pipe 221 are used to communicate with the device supplying the secondary refrigerant or the device to be charged, and the heat exchange pipe 221 is used to flow the secondary refrigerant to cool or heat the regenerator to realize the charging or discharging of the heat exchange module 2.

[0077] The heat exchange fins 222 can exchange heat with the heat exchange pipes 221 containing the secondary refrigerant, and a heat exchange surface is formed on the surface of the heat exchange fins 222 to exchange heat with the regenerator. The heat exchange assembly 22 of the embodiment adopts the combination of heat exchange pipes and heat exchange fins 222, which can increase the heat exchange area of the heat exchange assembly 22, improve the heat transfer efficiency, significantly improve the charging and discharging power of the heat exchange module 2, and greatly improve the cooling efficiency and cooling time of the heat exchange module 2. Moreover, the above design also increases the heat exchange area of the heat exchange assembly 22, and increases the contact area between the heat exchange assembly 22 and the regenerator, thereby improving the heat exchange efficiency of the regenerator and the charging or discharging efficiency of the heat exchange module 2.

[0078] Each heat exchange fin 222 is provided with a perforation, and the perforations of the plurality of heat exchange fins 222 are communicated to pass through the heat exchange pipes 221. The shape and size of the perforation are matched with the shape and size of the cross section of the heat exchange pipe 221.

[0079] It should be noted that in the embodiment, the heat exchange fins 222 and the heat exchange pipes 221 are not fixedly connected, that is, the distance between the adjacent two heat exchange fins 222 can be adjusted by applying an external force to the heat exchange fins 222 to move the heat exchange fins 222 along the heat exchange pipes 221, thereby adjusting the volume of the heat exchange space enclosed by the adjacent two heat exchange surfaces and changing the thermal resistance of the heat exchange assembly 22, so as to adjust the charging efficiency of the heat exchange module 2.

[0080] In the embodiment, the heat exchange fins 222 are made of aluminum.

[0081] In the embodiment, the plurality of heat exchange pipes 221 are vertically spaced. The inlets and outlets of the heat exchange pipes 221 are arranged on opposite sides of the whole formed by the plurality of heat exchange fins 222, i.e., the heat exchange pipes 221 penetrate the whole formed by the plurality of heat exchange fins 222, so that the heat exchange pipes 221 carrying the cold carrier can exchange heat with each heat exchange fin 222.

[0082] Specifically, each heat exchange pipe 221 includes a plurality of branch pipes 2211 which are transversely spaced through the plurality of heat exchange fins 222. That is, in the embodiment, all the branch pipes 2211 of each heat exchange assembly 22 are arranged in an array, and in the process of heat exchange between the plurality of branch pipes 2211 carrying the cold carrier and the plurality of heat exchange fins 222, the surface of the heat exchange fins 222 can be quickly and uniformly cooled or heated to form a heat exchange surface, so as to improve the heat exchange efficiency of the heat exchange assembly 22, the heat exchange efficiency of the cold storage agent, and the charging and discharging efficiency of the heat exchange module 2.

[0083] Each branch pipe 2211 has an inlet and an outlet, and the inlet and outlet of each branch pipe 2211 are arranged on opposite sides of the whole formed by the plurality of heat exchange fins 222.

[0084] In the embodiment, the heat exchange assembly 22 includes an inlet pipe 223 which communicates with the inlets of the heat exchange pipes 221. The heat exchange assembly 22 includes an outlet pipe 224 which communicates with the outlets of the heat exchange pipes 221. Specifically, the inlet pipe 223 communicates with the inlets of the plurality of branch pipes 2211 of the heat exchange pipes 221, and the outlet pipe 224 communicates with the outlets of the plurality of branch pipes 2211 of the heat exchange pipes 221.

[0085] That is, in the embodiment, the cold carrier is delivered into the plurality of heat exchange pipes 221 by the inlet pipe 223, and the cold carrier is delivered by the plurality of branch pipes 2211 of the heat exchange pipes 221, so that the outer surfaces of the plurality of branch pipes 2211 have a high or low temperature at the same time, and heat exchange with the plurality of heat exchange fins 222 at the same time. Thus, the surface of the heat exchange fins 222 can be quickly and uniformly cooled or heated to form a heat exchange surface, so as to improve the heat exchange efficiency of the heat exchange assembly 22, the heat exchange efficiency of the cold storage agent, and the charging and discharging efficiency of the heat exchange module 2. Similarly, the outlets of the plurality of branch pipes 2211 are connected by the outlet pipe 224 to realize the convergent delivery of the cold carrier. In addition, the above design can reduce the arrangement of the pipeline and simplify the structure of the heat exchange assembly 22.

[0086] It should be noted that the number of the shunt pipes 2211 is set according to the caliber of the liquid inlet pipe 223, specifically, the shunt pipes 2211 are arranged according to the flow rate of the cold carrier transported by the liquid inlet pipe 223 per unit time, to ensure that the cold carrier flows in the form of turbulent flow in each shunt pipe 2211, so that the flow rate of the cold carrier is high, to avoid the loss of heat or cold of the cold carrier, thereby improving the utilization rate of the heat or cold energy of the cold carrier.

[0087] Specifically, the liquid inlet pipe 223 extends vertically, and is located at the middle part of the heat exchange fin 222 in the transverse direction, so as to communicate with the plurality of shunt pipes 2211 of the heat exchange pipe 221. The arrangement form and structure of the liquid outlet pipe 224 are consistent with those of the liquid inlet pipe 223.

[0088] The first valve 41 is arranged on each liquid inlet pipe 223, and is used to control the on-off of the liquid inlet pipe 223. The second valve 42 is arranged on each liquid outlet pipe 224, and is used to control the on-off of the liquid outlet pipe 224.

[0089] In the embodiment, each heat exchange assembly 22 includes a heat assembly including a plurality of connecting plates 225 and a plurality of connecting rods 226. The plurality of connecting plates 225 are arranged at intervals, and the upper and lower ends of the adjacent two connecting plates 225 are respectively connected and fixed by at least one connecting rod 226, to form a frame whole. A plurality of heat exchange fins 222 are arranged at intervals between the adjacent two connecting plates 225, and each heat exchange pipe 221 passes through the plurality of connecting plates 225 and the plurality of heat exchange fins 222.

At this time, the plurality of first connecting components 31 are connected in parallel and communicated with each liquid inlet pipe 223 through a conveying pipe, and the plurality of second connecting components 32 are connected in parallel and communicated with each liquid outlet pipe 224 through an output pipe.

The inner diameter of the expansion groove is greater than the diameter of the connecting pipeline 311 and the inlet of the liquid pump 5, and the expansion tank 7 is arranged above the liquid pump 5.

[0107] In actual application, the cold carrier is delivered to the inside of the expansion tank 7 through the connecting pipeline 311. Since the inside of the expansion tank 7 has a large space, the expansion tank 7 can buffer and temporarily store the cold carrier. The cold carrier pumped by the liquid pump 5 is the part temporarily stored after being buffered by the expansion tank 7, which can improve the stability of the liquid pump 5 and enable the liquid pump 5 to continuously pump the cold carrier to ensure the normal supply of the cold carrier to the heat exchange module 2. In addition, when the temperature of the cold carrier rises and carries heat, the cold carrier may be gasified, which may cause the internal pressure of the pipeline assembly 3 and the heat exchange assembly 22 to rise. At this time, the space inside the expansion tank 7 can also provide a gasification space to accommodate the gasified cold carrier to stabilize the pressure.

[0108] In the embodiment, the surface of the heat exchange assembly 22 in contact with the cold storage agent, the inner surface of the shell 21 and the surface of the mounting frame are all provided with a protective layer. The protective layer is used to isolate the heat exchange assembly 22, the shell 21 and the mounting frame from the cold storage agent to avoid direct contact between the heat exchange assembly 22, the shell 21 and the mounting frame and the cold storage agent, thereby preventing corrosion and damage and improving the service life of the heat exchange assembly 22, the shell 21 and the mounting frame.

[0109] Specifically, the protective layer is formed by electrophoresis on the mounting frame, the shell 21 and the heat exchange assembly 22.

[0110] The outer surface of the shell 1 is provided with a heat insulation layer. The heat insulation layer is used for heat insulation of the heat exchange module 2 to improve the heat preservation of the heat exchange module 2, reduce the loss of cold energy of the cold storage agent and improve the utilization rate of energy.

[0111] In the embodiment, the heat insulation layer is made of high thermal resistance material. For example, the heat insulation layer is an aerogel layer. Compared with traditional polyurethane heat preservation, the aerogel layer used as the heat insulation layer of the heat exchange module 2 has better heat insulation effect and can better reduce the loss of cold energy stored by the cold storage agent.

[0112] The application also provides a cold storage vehicle including a vehicle body and a mobile cold storage device as described above. The mobile cold storage device is arranged on the vehicle body, and the vehicle body can realize the movement and transportation of the mobile cold storage device. In this way, the cold energy released when LNG is gasified in a fixed-position LNG gasification station can be stored and transported to a place where a cold energy keeping device needs to be cooled, and then the cold energy keeping device is cooled to realize the recycling of cold energy and the remote cooling of the cold energy keeping device, so that the LNG cold energy can be used efficiently, and the economic benefit is improved.
