Furthermore, the plurality of heat-conducting spaces can be interconnected, so that the phase-change refrigerant can be filled as much as possible in the refrigerant plate receiving cavity. Furthermore, since the heat-conducting member is arranged in the receiving cavity, the overall strength and hardness of the refrigerant plate are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Reference Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a cold storage plate 100 provided for some embodiments of the application. Figure 2 for Figure 1 A schematic cross-sectional view of the cold storage plate 100 at AA in FIG. A cold storage plate 100 provided in one embodiment of the present application includes a shell 1 having a receiving chamber R for receiving a phase-change refrigerant and a heat conductive member disposed in the receiving chamber R. Since cold energy will be quickly transferred from a structure with high thermal conductivity to a structure with low thermal conductivity, cold energy will be preferentially transferred to a structure with low thermal resistance. By providing a heat conductive member with higher thermal conductivity than the phase-change refrigerant in the receiving chamber R, the cold energy received by the outer surface of the cold storage plate 100 is preferentially dispersed and transferred to the heat conductive member and then to the phase-change refrigerant, thereby accelerating the solidification process of the refrigerant. By making the thermal conductivity of the heat conductive member greater than the thermal conductivity of the phase-change refrigerant, the cold energy of the heat conductive member can be quickly transferred to the phase-change refrigerant, thereby increasing the solidification rate of the refrigerant. Among them, the heat conductive member refers to a component used to effectively conduct cold energy.

[0046] The heat conducting member includes a first heat conducting part 21 and a second heat conducting part 22 connected to each other, wherein the first heat conducting part 21 extends in a first direction F1, and the second heat conducting part 22 extends in a second direction F2. The arrangement of the first heat conducting part 21 and the second heat conducting part 22 divides the accommodating cavity R into a plurality of heat conducting spaces that are interconnected.

[0047] The heat transfer space refers to a medium area that can achieve cold transfer. The material in this area transfers heat to the low-temperature part through heat conduction to store cold. Multiple heat transfer spaces can be interconnected, and the materials in each area can flow to each other.

[0048] The first direction F1 and the second direction F2 intersect each other, and the first heat conducting portion 21 is extended in the first direction F1, and the second heat conducting portion 22 is extended in the second direction F2, then the first heat conducting portion 21 and the second heat conducting portion 22 intersect each other and are connected together. It can be understood that the first direction F1 and the second direction F2 are only for the convenience of description, and are not intended to limit the embodiments of the present application.

[0049] In this way, due to the high thermal conductivity of the heat conductive element, the cold is transferred to the phase-change refrigerant in the heat conductive space. Furthermore, because the volume of the formed heat conductive space is smaller than that of the overall accommodating cavity R, and the cold is conducted from the surface of the heat conductive element to the center of the formed heat conductive space, this conduction path is smaller than the conduction path without a heat conductive element. The smaller the conduction path, the smaller the heat transfer resistance, so the phase-change refrigerant in the heat conductive space solidifies faster, thereby accelerating the cold charging rate of the cold storage plate 100. And multiple heat conductive spaces can be interconnected, so that the phase-change refrigerant can be filled as much as possible in the accommodating cavity R of the cold storage plate 100. Furthermore, since the heat conductive element is arranged in the accommodating cavity R, the overall strength and hardness of the cold storage plate 100 are improved.

[0050] At present, porous skeleton structures are often arranged in the accommodating cavity R of the cold storage plate 100 to improve the cold storage efficiency of the cold storage plate 100. However, porous metal skeletons have the disadvantage of requiring low corrosiveness of the phase change cold storage agent, porous carbon-based skeletons have the disadvantage of poor mechanical properties, and porous ceramic skeletons have the disadvantage of high preparation costs. In addition, the porous skeleton structure will occupy a large space in the shell 1 of the cold storage plate 100, and only a small amount of phase change cold storage agent can be filled into the cold storage plate 100, which cannot make the cold storage plate 100 have good cold storage performance. Compared with the use of a porous skeleton structure in the shell 1 of the cold storage plate 100 to reduce the charging time of the cold storage plate 100, the heat conductive member adopted in the present application is arranged in the accommodating cavity R, and there are no excessive restrictions on the material of the heat conductive member, and the accommodating cavity R is divided into a plurality of interconnected heat conductive spaces by connecting the first heat conductive portion 21 and the second heat conductive portion 22 extending in two different directions, so that the phase change refrigerant in each heat conductive space can change phase more quickly. And because each heat conductive space is connected, the phase change refrigerant in the cold storage plate 100 after charging can completely wrap the heat conductive member and completely fill the accommodating cavity R.

[0051] Compared to reducing the thickness of the cold storage plate 100 to shorten the cold charging time and improve the cold charging efficiency of the cold storage plate 100, simply reducing the thickness of the cold storage plate 100 will reduce the strength of the cold storage plate 100 and reduce the cold storage capacity. The heat conductive member adopted in the present application not only improves the cold charging time of the cold storage plate 100, but also further improves the strength of the cold storage plate 100.

[0052] In some embodiments of the present application, see Figure 1 and Figure 2 , and refer to Figure 3 , Figure 3 for Figure 1 Schematic cross-sectional view of the cold storage plate 100 at CC in FIG. A plurality of first heat conducting parts 21 and second heat conducting parts 22 are provided, and all first heat conducting parts 21 are sequentially spaced along the second direction F2, and all second heat conducting parts 22 are sequentially spaced along the first direction F1, and each of all first heat conducting parts 21 is connected to any one of all second heat conducting parts 22. In this way, the first heat conducting parts 21 and the second heat conducting parts 22 can form a plurality of quadrilateral structures with the same structure and the same size.

[0053] With such a configuration, it is only necessary to use a plurality of first heat-conducting parts 21 of the same shape and size and a plurality of second heat-conducting parts 22 of the same size and shape as the main materials, which is low in cost and easy to process and manufacture. Then, it is only necessary to connect each of all the first heat-conducting parts 21 with any of all the second heat-conducting parts 22 to divide the accommodating cavity R into a plurality of heat-conducting spaces, which is convenient for processing and manufacturing. In addition, the first heat-conducting parts 21 and the second heat-conducting parts 22 can form a plurality of quadrilateral structures, which are easier to splice and easier to form a plurality of regular grid structures.

[0054] It can be understood that the first direction F1 and the second direction F2 are two different directions, and the first direction F1 and the second direction F2 are only for the convenience of description and are not intended to limit the scope of the present application.

[0055] In some other embodiments, a heat conducting member that can form a triangular structure, a pentagonal structure, or a hexagonal structure may also be used.

[0056] In some embodiments of the present application, see Figures 1 to 3 , all the first heat-conducting parts 21 are arranged at equal intervals along the second direction F2; and / or, all the second heat-conducting parts 22 are arranged at equal intervals along the first direction F1; and / or, the distance between any two adjacent first heat-conducting parts 21 along the second direction F2 is equal to the distance between any two adjacent second heat-conducting parts 22 along the first direction F1.

[0057] In some embodiments, including but not limited to the following:

[0058] In the case where all the first heat conducting parts 21 are arranged at equal intervals along the second direction F2, by arranging all the first heat conducting parts 21 at equal intervals along the second direction F2, the distance between two adjacent first heat conducting parts 21 is made consistent, so that the structural arrangement of the first heat conducting parts 21 can be made more uniform and orderly, thereby making the phase change refrigerant able to transfer cold more evenly and reliably in the multiple heat conducting spaces divided by the first heat conducting parts 21, thereby optimizing the cold transfer path between the components in the accommodating cavity R, and improving the uniformity and reliability of the cold transfer.

[0059] In the case where all the second heat conducting parts 22 are arranged at equal intervals along the first direction F1, by arranging all the second heat conducting parts 22 at equal intervals along the first direction F1, the distance between two adjacent second heat conducting parts 22 is made consistent, so that the structural arrangement of the second heat conducting parts 22 can be made more uniform and orderly, thereby making the phase change refrigerant able to transfer cold more evenly and reliably in the multiple heat conducting spaces divided by the second heat conducting parts 22, thereby optimizing the cold transfer path between the components in the accommodating cavity R, and improving the uniformity and reliability of the cold transfer.

[0060] When the spacing between any two adjacent first heat conducting parts 21 along the second direction F2 is equal to the spacing between any two adjacent second heat conducting parts 22 along the first direction F1, by setting the spacing between any two adjacent first heat conducting parts 21 in the second direction F2 to be equal to the spacing between any two adjacent second heat conducting parts 22 in the first direction F1, the distribution of the first heat conducting parts 21 and the second heat conducting parts 22 is made more uniform, so that the phase change refrigerant can achieve phase change more effectively.

[0061] When all the first heat conducting parts 21 are arranged at equal intervals along the second direction F2, and all the second heat conducting parts 22 are arranged at equal intervals along the first direction F1, the first heat conducting parts 21 and the second heat conducting parts 22 can form a plurality of quadrilateral structures of the same shape and size, further optimizing the cold transfer path between the various components in the accommodating cavity R, and improving the uniformity and reliability of cold transfer.

[0062] When all the first heat-conducting parts 21 are arranged at equal intervals along the second direction F2, and all the second heat-conducting parts 22 are arranged at equal intervals along the first direction F1, and the spacing between any two adjacent first heat-conducting parts 21 in the second direction F2 and the spacing between any two adjacent second heat-conducting parts 22 in the first direction F1 are equal, the four sides of the multiple quadrilateral structures formed by the first heat-conducting parts 21 and the second heat-conducting parts 22 are equal. Quadrilaterals with equal sides can evenly distribute the cold in the directions where the different sides are located, thereby improving the thermal conductivity of the heat-conducting member. In addition, quadrilaterals with equal sides can be better arranged, thereby improving the space utilization rate in the accommodating cavity R.

[0063] The above-mentioned “all first heat-conducting portions 21 are arranged at equal intervals along the second direction F2”, “all second heat-conducting portions 22 are arranged at equal intervals along the first direction F1”, and “the distance between any two adjacent first heat-conducting portions 21 along the second direction F2 is equal to the distance between any two adjacent second heat-conducting portions 22 along the first direction F1” can be arbitrarily combined and set according to actual conditions.

[0064] In some embodiments of the present application, continue to refer to Figures 1 to 3 , and refer to Figure 4 , Figure 4 for Figure 1 The cross-sectional diagram of the cold storage plate 100 at DD in FIG. The heat conducting member is an integrally formed member; and / or, two opposite ends of the first heat conducting portion 21 arranged along the first direction F1 are respectively connected to the inner wall of the accommodating cavity R; and / or, two opposite ends of the second heat conducting portion 22 arranged along the second direction F2 are respectively connected to the inner wall of the accommodating cavity R.

[0065] In the case where the heat conductor is an integrally formed part, the integrally formed part refers to a part in which multiple parts are combined into a complete part through a one-time molding process during the manufacturing process. This manufacturing method can be achieved through injection molding, die casting, forging, extrusion, etc. Compared with the method of independently processing and assembling the first heat conducting part 21 and the second heat conducting part 22, the integrally formed part can be manufactured into an overall structure through a one-time molding process, reducing the process and assembly time in the manufacturing process. Moreover, the manufacturing process of the integrally formed part can reduce joints, seams and gaps, and reduce factors that may cause loosening, leakage or damage, which helps to improve the structural strength and reliability of the heat conductor.

[0066] In the case where the two ends of the first heat-conducting part 21 that are relatively arranged along the first direction F1 are respectively connected to the inner wall of the accommodating chamber R, by connecting the two ends of the first heat-conducting part 21 that are relatively arranged along the first direction F1 to the inner wall of the accommodating chamber R, the two ends of the first heat-conducting part 21 that are relatively arranged in the first direction F1 can quickly transfer cold energy to the inner wall of the accommodating chamber R. It can be understood that since the cold energy will be quickly transferred from the first wall B1 to the various inner walls of the cold storage plate 100, and then transferred to the first heat-conducting part 21 connected thereto through the various inner walls, the cold energy will be transferred to various parts of the heat-conducting part. If one end of the first heat-conducting part 21 that is relatively arranged along the first direction F1 is connected to the inner wall of the accommodating chamber R, and the other end of the first heat-conducting part 21 that is relatively arranged along the first direction F1 is not connected to the inner wall of the accommodating chamber R, the first heat-conducting part 21 can only quickly transfer cold energy through the inner wall connected to the accommodating chamber R.

[0067] The two ends of the first heat conducting part 21 that are relatively arranged along the first direction F1 are respectively connected to the inner wall of the accommodating cavity R, so that the two ends of the first heat conducting part 21 that are relatively arranged in the first direction F1 can quickly transfer cold energy to the inner wall of the accommodating cavity R, further improving the cold energy transfer efficiency of the cold storage plate 100.

[0068] When the two ends of the second heat-conducting portion 22 that are relatively arranged along the second direction F2 are respectively connected to the inner wall of the accommodating cavity R, similarly, the two ends of the second heat-conducting portion 22 that are relatively arranged along the second direction F2 are respectively connected to the inner wall of the accommodating cavity R, so that the two ends of the second heat-conducting portion 22 that are relatively arranged in the second direction F2 can quickly transfer cold to the inner wall of the accommodating cavity R, further improving the cold transfer efficiency of the cold storage plate 100, and accelerating the transfer of cold between the inner wall of the accommodating cavity R and the heat-conducting component.

[0069] When both ends of the first heat conducting part 21 that are relatively arranged along the first direction F1 are respectively connected to the inner wall of the accommodating chamber R, and both ends of the second heat conducting part 22 that are relatively arranged along the second direction F2 are respectively connected to the inner wall of the accommodating chamber R, the transfer of cold between the inner wall of the accommodating chamber R and the heat conducting part can be further accelerated.

[0070] In some other embodiments, reference may be made to Figure 2 The cold storage plate has a first inner wall NB1 with the largest outer surface area, and one end of the first heat conducting part 21 and / or the second heat conducting part 22 can be connected to the first inner wall of the accommodating cavity. In this way, since the cold amount is usually quickly transferred to the surface with the largest area of ​​the component, the first inner wall usually has a larger cold amount. Therefore, connecting the first heat conducting part 21 and / or the second heat conducting part 22 to the first inner wall can once again speed up the transfer of cold between the inner wall of the accommodating cavity R and the heat conducting part.

[0071] The above-mentioned "the heat conducting part is an integrally formed part", "the two ends of the first heat conducting part 21 oppositely arranged along the first direction F1 are respectively connected to the inner wall of the accommodating cavity R", and "the two ends of the second heat conducting part 22 oppositely arranged along the second direction F2 are respectively connected to the inner wall of the accommodating cavity R." can be arbitrarily combined and arranged according to actual conditions.

[0072] You can continue to refer to Figure 1 The structure of the shell 1 is a square structure. In some other embodiments, the shell 1 can also take a cylindrical structure, a triangular prism structure, etc., which will not be described here. In order to facilitate the introduction of the structure of the cold storage plate 100, the structure of the shell 1 is specifically introduced as a square structure.

[0073] In some embodiments of the present application, continue to refer to Figure 1 and Figure 3 , the first direction F1 , the second direction F2 and the thickness direction F3 of the shell 1 are perpendicular to each other; and / or the thickness of the shell 1 is 1 mm to 2 mm.

[0074] In the case where the first direction F1, the second direction F2 and the thickness direction F3 of the shell 1 are perpendicular to each other, by setting the first direction F1, the second direction F2 and the thickness direction F3 of the shell 1 perpendicular to each other, the multiple quadrilateral structures of the same structure and the same size formed by the first heat conducting part 21 and the second heat conducting part 22 are regular quadrilateral structures, and multiple regular quadrilateral structures are more convenient to splice and arrange in an orderly manner than multiple rhombus structures. In addition, the first direction F1 and the second direction F2 are both perpendicular to the thickness direction F3 of the shell 1, so that the planes parallel to the first direction F1 and the second direction F2 can be perpendicular to the thickness direction F3 of the shell 1, thereby increasing the strength of the cold storage plate 100 in the thickness direction. In addition, each side of the shell 1 of the square structure is perpendicular to the other two sides, and setting the first direction F1, the second direction F2 and the thickness direction F3 of the shell 1 perpendicular to each other helps the first heat conducting part 21 and the second heat conducting part 22 to be arranged in an orderly manner according to the square shape of the shell 1.

[0075] Continue to refer to Figure 1 When the thickness of the shell 1 is set to 1 mm to 2 mm, for example, the thickness of the shell 1 can be 1 mm, 1.5 mm, 2 mm, etc. When the thickness of the shell is set within the range of 1 mm to 2 mm, the cold storage plate 100 can have a certain pressure bearing strength under the premise of having a small thermal resistance.

[0076] The above-mentioned “the first direction F1, the second direction F2 and the thickness direction F3 of the shell 1 are perpendicular to each other” and “the thickness of the shell 1 is 1 mm to 2 mm” can be arbitrarily combined and set according to actual conditions.

[0077] In some embodiments of the present application, see Figure 1 and Figure 2 The shell 1 includes a first wall B1 located on the cooling side of the cold storage plate 100. The cooling side of the cold storage plate 100 is a side of the cold storage plate 100 for receiving cold energy. The surface of the first wall B1 facing away from the accommodating cavity R is configured as a curved surface HM.

[0078] Compared with setting the side surface of the first wall B1 away from the accommodating cavity R as a plane, the curved surface HM has a larger area and can absorb or dissipate more cold energy. In addition, the curved surface HM can change the emission or absorption angle of thermal radiation, can absorb cold energy in a larger range, and transfer the absorbed cold energy to the bottom surface DM2 and the top surface DM1 of the shell 1 more quickly through the curved direction of the curved surface HM. Figure 1 It can be seen from the figure that the bottom surface DM2 and the top surface DM1 are the surfaces with the largest areas among the outer surfaces of the cold storage plate 100 , so during the cold conduction process, the cold can be quickly transferred to the bottom surface DM2 and the top surface DM1 .

[0079] In some embodiments of the present application, see Figure 1 and Figure 2 The shell 1 also includes a second wall B2 arranged opposite to the first wall B1, and an interface portion J1 arranged on the second wall B2. The interior of the interface portion J1 is connected to the accommodating chamber R. The interface portion J1 is used to input the phase-change refrigerant. The cold storage plate 100 also includes a cover body 3, which is detachably covered on the interface portion J1.

[0080] The setting of the interface J1 makes it convenient to input the phase-change refrigerant, and the phase-change refrigerant can be directly injected into the accommodating chamber R through the interface J1. Since the cover 3 is detachable, it means that when the refrigerant needs to be replaced or maintained, the cover 3 can be easily opened for operation, and after the phase-change refrigerant is completely poured into the shell 1, the shell 1 can be sealed. The interface J1 is set on the second wall B2 opposite to the first wall B1, that is, the phase-change refrigerant enters the shell 1 from the second wall B2 opposite to the cooling side. It can be understood that the cold amount is arranged so that the cold amount close to the cooling side is greater than the cold amount away from the cooling side, so the phase-change refrigerant enters the shell 1 away from the cooling side, reducing the risk that the phase-change refrigerant is concentrated near the cooling side and solidified, while the phase-change refrigerant away from the cooling side is not solidified.

[0081] In some embodiments of the present application, see Figures 1 to 3 The second wall B2 has a recessed portion S that is recessed toward the accommodating chamber R, and the interface portion J1 is disposed on the wall of the recessed portion S.

[0082] By providing the recessed portion S, when the phase-change refrigerant is filled into the shell 1, the phase-change refrigerant will be contained as little as possible around the recessed portion S. Therefore, when the liquid phase-change refrigerant changes to a solid state after being cooled, the shell 1 will shrink, reducing the risk of the shell 1 partially cracking due to the volume reduction of the phase-change refrigerant during the phase change process. When the solid phase-change refrigerant changes to a liquid state, the shell 1 will expand, reducing the risk of the shell 1 being damaged due to the volume increase of the phase-change refrigerant during the phase change process.

[0083] In some embodiments of the present application, see Figures 1 to 3 , along the direction from the first wall B1 to the second wall B2, the ratio of the dimension C1 of the recess S to the dimension C2 of the housing 1 is 0.015 to 0.025, and the ratio can be 0.015, 0.02 or 0.025, etc. The ratio of the dimension K1 of the recess S along the second direction F2 of the housing 1 to the width K2 of the housing 1 in the second direction F2 is 0.3 to 0.5, and the ratio can be 0.3, 0.4 or 0.5, etc. Among them, the direction from the first wall B1 to the second wall B2 is parallel to the first direction F1.

[0084] If the size ratio is too large, the filling capacity of the phase-change refrigerant will be reduced, resulting in low refrigerant performance of the cold storage plate 100. If the size ratio is too large, the excessive proportion of the recess S will reduce the strength of the cold storage plate 100. If the size ratio is too small, it will be difficult to achieve the above-mentioned advantages of reducing damage to the shell 1 and reducing cracking of the shell 1. In the direction from the first wall B1 to the second wall B2, the ratio of the size C1 of the recess S to the size C2 of the shell 1 is 0.015 to 0.025, and the ratio of the size K1 of the recess S along the second direction F2 of the shell 1 to the width K2 of the shell 1 in the second direction F2 is 0.3 to 0.5. The above-mentioned strength problem and the problem of the rupture life of the shell 1 can be balanced, so that the shell 1 is not easily damaged under the premise that the cold storage plate 100 has a certain strength.

[0085] In some embodiments of the present application, please continue to refer to Figure 1 , and refer to Figure 5 , Figure 5 for Figure 1 FIG. 1 is a partial enlarged schematic diagram of the cold storage plate 100 at E. The cold storage plate 100 further includes a sealing member 4, which is disposed between the cover body 3 and the interface portion J1.

[0086] In this way, when the cover 3 is connected to the interface portion J1 , the risk of the phase-change refrigerant flowing out of the shell 1 and the risk of external impurities entering the shell 1 can be effectively reduced.

[0087] In some embodiments of the present application, see Figure 5The sealing member 4 is configured as a sealing ring 4a, and the cross-sectional shape of the sealing ring 4a is a trapezoid.

[0088] In this way, since the cross-sectional shape of the sealing ring 4a is set to a trapezoid, when the sealing ring 4a is compressed, the difference between the upper and lower bases of the trapezoid will cause the sealing ring 4a to move in the inner diameter or outer diameter direction, thereby generating additional pressure at the interface and enhancing the sealing effect.

[0089] Based on the same inventive concept, an embodiment of the present application provides a refrigerated vehicle, comprising the cold storage plate 100 in any of the above embodiments.

[0090] The advantages of the above cold storage plate 100 are also possessed by the refrigerated truck, which will not be elaborated here.

[0091] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
