[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] [First embodiment]

[0025] See also Figure 1 , which is a schematic structural diagram of a cold storage strip capable of draining condensed water provided in the first embodiment of the present invention; the cold storage strip capable of draining condensed water 100, for example, includes a plurality of cold storage tubes 30, a cold storage tube sleeve 10 sleeved outside the plurality of cold storage tubes 30, a phase change material layer 20 sandwiched between the cold storage tubes 30 and the cold storage tube sleeve 10, and a water collecting tank 34 connected to the cold storage tube sleeve 10.

[0026] See also Figure 2 Specifically, the cold storage pipe sleeve 10 includes a mounting panel 11, two side panels 12, a curved panel 13 and two end panels (not shown in the figure); wherein the two side panels 12 are respectively connected between the mounting panel 11 and the curved panel 13, and the two end panels are respectively covered at both ends of the mounting panel 11, the two side panels 12 and the curved panel 13, and the two side panels 12, the mounting panel 11, the curved panel 13 and the two end panels form a cold storage pipe accommodating chamber (not marked in the figure). For example, the mounting panel 11, the two side panels 12, the curved panel 13 and the two end panels are respectively made of aluminum alloy plates, which can be integrally extruded to obtain the cold storage pipe sleeve 10, and of course can also be welded to obtain the cold storage pipe sleeve 10.

[0027] Among them, for example, multiple cold storage tubes 30 are respectively inserted into the cold storage tube sleeve 10 from one of the end plates to enter the cold storage tube accommodating cavity, and are respectively inserted from the other opposite end plate, so that the two ends of each cold storage tube 30 are respectively exposed on both sides of the cold storage tube sleeve 10. Of course, multiple cold storage tubes 30 can also be completely wrapped in the cold storage tube sleeve 10, and at the same time, a multi-pass connecting pipe is respectively arranged at the position close to the two end plates in the cold storage tube accommodating cavity to respectively connect multiple cold storage tubes 30, and the two multi-pass connecting pipes respectively extend a connecting opening from the end plate. For example, the cold storage tube 30 can be composed of two, and the two cold storage tubes 30 are respectively arranged between the two side panels 12, and the two cold storage tubes 30 are arranged in a row between the two side panels 12, thereby increasing the height of the side panels 12. .

[0028] The water collecting tank 40 is connected to the side of the curved panel 13 away from the two side panels 12 and the installation panel 11. For example, a connector 41 is connected to the side of the curved panel 13 away from the two side panels 12, and the connector 41 is fixedly connected to the water collecting tank 40. The condensed water generated on the outer wall of the cold storage pipe sleeve 10 slides down from the two side panels 12, passes through the curved panel 13, and is finally collected in the water collecting tank 40 and then discharged. For example, there can be multiple connectors 41, and multiple connectors 41 are evenly connected to the middle part of the curved panel 13 along the length direction of the cold storage strip 100, and multiple connectors 41 are connected to the water collecting tank 40; the width of the water collecting tank 40 is greater than the distance between the two side panels 12, so that the two sides of the water collecting tank 40 exceed the corresponding side panels 12 respectively, so that the condensed water directly falling from the side panels 12 can be collected. Among them, the phase change material layer 20 can be a primary phase change material, and can preferably be a phase change material with large latent heat, good reversibility of the phase change process, non-toxicity, and non-corrosiveness to metals. For example, a mixture of water and additives can be used, and the additive can be an existing cold storage phase change material. The filling rate of the phase change material layer 40 in the cold storage tube accommodating cavity is 80% to 85%; and a coolant can flow in the cold storage tube 20. The coolant has the characteristics of being non-toxic, good chemical stability, high specific heat, low viscosity, and as large a thermal conductivity as possible, and is preferably a 50% ethylene glycol aqueous solution.

[0029] To facilitate a clearer understanding of this embodiment, Figure 1-Figure 2 , the specific implementation of the cold storage strip 100 capable of draining condensed water in this embodiment is described in detail.

[0030] Preferably, the cold storage strip 100 further includes, for example, a plurality of heat dissipation fins 31, which are evenly connected to the outer wall of each cold storage tube 30 in the circumferential direction. The plurality of heat dissipation fins 31 are used to increase the contact area between the cold storage tube 30 and the phase change material layer 20, thereby improving the cold charging efficiency and reducing the cold charging time. For example, in the process of introducing the coolant into the cold storage tube 30, the phase change material layer 20 absorbs the cold of the coolant through direct contact with the cold storage tube 20 and direct contact with the first heat conducting fin 40, thereby completing the cold charging quickly and efficiently.

[0031] Preferably, the cold storage bar 100 further includes a plurality of support members 32, which are connected between two adjacent cold storage tubes 30, between the cold storage tube 30 and the curved panel 13, between the cold storage tube 30 and the side panel 12, or between the cold storage tube 30 and the mounting panel 11. The plurality of support members 32 are used to strengthen the connection strength between the plurality of cold storage tubes 30 and the cold storage tube sleeve 10, thereby improving the stability of the cold storage bar 100.

[0032] Preferably, the cold storage strip 100 further includes water storage grooves (not shown in the figure) respectively arranged on the two side panels 12. The water storage grooves (not shown in the figure) are grooves on the side panels 12 that are sunken toward the cold storage tube accommodating chamber. The water storage grooves (not shown in the figure) can collect condensed water on the side panels 12. When multiple cold storage tubes 30 are arranged, the height of the side panels 12 will be too long, so that the condensed water on the side panels 12 may fall directly under the action of gravity before sliding to the curved panel 13 due to the excessive amount of condensed water collected. The water storage grooves (not shown in the figure) can divide the side panels 12 with too long height into multiple sections, so the condensed water collected on the side panels 12 above the water storage grooves (not shown in the figure) will slide into the water storage grooves (not shown in the figure); and the condensed water collected on the side panels 12 below the water storage grooves (not shown in the figure) will slide through the curved panel 13 into the water collection groove 40.

[0033] In a specific embodiment, the cold storage strip 100 further includes a first guide rib (not shown in the figure), which is disposed in the water storage tank (not shown in the figure) and connected to the side panel 22.

[0034] Preferably, the cold storage strip 100 further includes, for example, a plurality of second guide fins 16, which are respectively connected to a side of the curved panel 13 away from the cold storage tube accommodating chamber; condensed water on the curved panel 13 can drip into the water collecting tank 40 through the second guide fins 16. For example, the plurality of second guide fins 16 are respectively parallel to the connecting member 41, and the plurality of second guide fins 16 are respectively directed to the water collecting tank 40.

[0035] [Second embodiment]

[0036] See also Figure 3 , which is a schematic diagram of the structure of a cold storage assembly 200 provided in the second embodiment of the present invention.

For example, the brine input manifold 210 and the brine output manifold 220 are respectively provided with a plurality of cold storage bar connection openings (not marked in the figure), and the cold storage bar connection openings are, for example, provided with internal threads, and the openings at both ends of the cold storage tube 30 are respectively provided with matching external threads, and the plurality of cold storage tubes 30 are respectively connected between the brine input manifold 210 and the brine output manifold 220 by threaded connection; of course, other methods can also be used to detachably connect the cold storage tube 30 between the brine input manifold 210 and the brine output manifold 220, which will not be repeated here.

[0038] Furthermore, the cold storage assembly 200 further includes, for example, at least one brine transfer header 230, and at least one brine transfer header 230 is disposed between the brine input header 210 and the brine output header 220. For example, a brine transfer header 230 is provided, and a plurality of cold storage bars 100 capable of draining condensed water are distributed in two rows, wherein a portion of the cold storage bars 100 capable of draining condensed water is connected between the brine input header 210 and the brine transfer header 230, and another portion of the cold storage bars 100 capable of draining condensed water is connected between the brine output header 220 and the brine transfer header 230, and the connection positions of the plurality of cold storage bars 100 capable of draining condensed water on the brine transfer header 230 are different. Of course, by providing more than two refrigerant transfer headers 230 , a plurality of cold storage strips 100 capable of discharging condensed water can be connected between the refrigerant input header 210 and the refrigerant output header 220 in the form of three or more rows.

[0039] [Third embodiment]

[0042] Preferably, the cold storage assembly 200 can be arranged according to the length of the carriage, so the cold storage assembly 200 can be set to have one row of cold storage strips 100 that can drain condensed water or multiple rows of cold storage strips 100 that can drain condensed water according to the length of the carriage; please refer to the second embodiment for details, which will not be repeated here.

[0043] Of course, the refrigerated compartment can also be provided with a plurality of groups of refrigerant input ends and refrigerant output ends, wherein each group of refrigerant input ends and refrigerant output ends is respectively connected to a single-row structured cold storage component 200; in this way, during the cold charging process, each cold storage strip 100 that can discharge condensed water can be in contact with the refrigerant with sufficient cold capacity, and the temperature difference is relatively large, thereby improving the cold capacity transfer efficiency.

[0044] The refrigerated truck can be charged with cold using a cold charging machine, and the process includes, for example: connecting a pipe used by the cold charging machine to output a coolant with sufficient cold capacity to the coolant input end, and connecting a pipe used by the cold charging machine to recover a coolant with insufficient cold capacity to the coolant output end; turning on the cold charging machine to pump the coolant with sufficient cold capacity into each cool storage bar 100 that can drain condensed water in the cool storage component 200, and then returning the coolant with insufficient cold capacity that has been charged to the cold charging machine until the multiple cool storage bars 100 that can drain condensed water in the cool storage component 200 are completely charged with cold.

[0045] During the cold chain transportation of the refrigerated truck, condensed water generated by each cold storage bar 100 is collected in the drainage assembly 50 and the drainage groove 70 respectively, and discharged through the drainage port.
