[0040] Figure 1 FIG. 1 shows a schematic structural diagram of a cold storage plate 10 in an embodiment of the present application. Figure 2 FIG. 1 shows a top view of a cold storage plate 10 in an embodiment of the present application. Figure 3 A cross-sectional view of a cold storage plate 10 in an embodiment of the present application is shown.

[0041] See also Figure 1-Figure 3A cold storage plate 10 provided in an embodiment of the present application includes a plate body 100 and a baffle 200. The plate body 100 has a cold storage chamber Q1 for accommodating phase change material, and the baffle 200 is disposed in the cold storage chamber Q1, and divides the cold storage chamber Q1 into a constrained melting chamber Q11 and a non-constrained melting chamber Q12, wherein the baffle 200 is configured to limit the phase change material in the constrained melting chamber Q11 from flowing toward the bottom wall of the cold storage chamber Q1, so that the melting speed of the phase change material in the constrained melting chamber Q11 is lower than the melting speed of the phase change material in the non-constrained melting chamber Q12.

[0042] The side wall of the plate body 100 has a certain thickness. The plate body 100 is a hollow shell with a certain thickness and can be used to accommodate the phase change material.

[0043] The material of the plate body 100 can be high-density polyethylene (HDPE), which has good corrosion resistance but low thermal conductivity. Optionally, considering the thermal resistance and strength requirements of the cold storage plate 10, the thickness of the side wall of the plate body 100 should not be too large or too small. The thickness of the side wall of the plate body 100 is preferably selected to be 1mm~2mm.

[0044] In the non-constrained melting chamber Q12, the heat transfer of the phase change material in the initial stage includes heat conduction. As time goes by, the phase change material settles to the bottom wall of the cold storage chamber Q1 and gets closer to the part to be cooled (the part to be cooled is the object of cooling of the cold storage plate 10 of this application, such as the cold chain products transported by the cold storage cold chain vehicle), thereby undergoing a phase change and melting (from solid to liquid). In addition, the downward movement of the solid phase change material will also generate additional pressure on the liquid phase change material at the bottom, forcing it to rise to the top along the left and right walls, thereby generating a natural convection cycle in the non-constrained melting chamber Q12 to further increase the heat exchange rate.

[0045] The cold storage plate is placed against the wall in the cold chain vehicle. The heat generated by the cooling component raises the air temperature in the vehicle. When the air passes over the side of the cold storage plate facing the vehicle compartment, the phase change material in the cold storage cavity begins to melt. The phase change material on the side close to the component to be cooled melts into liquid first. If the solid phase change material does not settle and squeeze the liquid phase change material, the liquid will continue to accumulate on the side close to the product side, and a liquid film of a certain thickness will cause the thermal resistance to increase. The sedimentation of the solid phase change material in the present application allows the liquid phase change material to move upward and climb to a certain height before washing the solid surface downward along the surface of the solid phase change material, so that the liquid near the product side will not continue to accumulate, and at the same time, local natural convection heat exchange is formed, and the natural convection heat exchange rate is faster than that of heat conduction, which is beneficial to improve the heat exchange efficiency.

[0046] In the constrained melting chamber Q11, since the baffle 200 restricts the phase change material in the constrained melting chamber Q11 from flowing toward the bottom wall close to the cold storage chamber Q1, the phase change material in the constrained melting chamber Q11 is roughly in a static state, and it is difficult for the liquid phase change material to move upward and natural convection to occur. The heat transfer process between the phase change material in the constrained melting chamber Q11 and the part to be cooled is mainly based on heat conduction; therefore, compared with the melting speed of the phase change material in the constrained melting chamber Q11, the melting speed of the phase change material in the non-constrained melting chamber Q12 is faster and the cooling rate is greater, which is beneficial to cooling the cold chain products transported by the cold storage type cold chain vehicle; in addition, the melting speed of the phase change material in the constrained melting chamber Q11 is slower, which is beneficial to reduce the temperature fluctuation in the vehicle while extending the cooling time, thereby improving the quality of the cold chain products, increasing the transportation distance of the cold storage type cold chain vehicle, and solving the problems of short transportation distance, low transportation efficiency, and temperature fluctuation of traditional cold storage type cold chain vehicles.

[0047] In some embodiments, please refer to Figure 3-Figure 5 The baffle 200 includes at least two first sub-baffles 210 , and the at least two first sub-baffles 210 are arranged in the cold storage chamber Q1 at intervals along a first direction F1 , and the first direction F1 is parallel to the thickness direction of the plate body 100 .

[0048] By way of example, the number of the first sub-baffles 210 is two.

[0049] Since at least two first sub-baffles 210 are arranged in the cold storage chamber Q1 at intervals along the first direction F1, and the first direction F1 is parallel to the thickness direction of the plate body 100, at least two first sub-baffles 210 can be well utilized to limit the phase change material in the restrictive melting chamber Q11 to flow toward the bottom wall of the cold storage chamber Q1, thereby better slowing down the melting speed of the phase change material in the restrictive melting chamber Q11, which is beneficial to prolonging the cooling time and increasing the transportation distance of the cold storage cold chain vehicle.

[0050] In some embodiments, the baffle 200 further includes at least two second sub-baffles 220, which are arranged in the cold storage chamber Q1 along the second direction F2 at intervals, and the first sub-baffle 210 and the second sub-baffle 220 define a constrained melting chamber Q11. The first direction F1 and the second direction F2 intersect each other.

[0051] It can be understood that the area of ​​the cold storage chamber Q1 other than the constrained melting chamber Q11 is the non-constrained melting chamber Q12.

[0052] The second direction F2 can be parallel to the width direction of the plate body 100. For example, when the cold storage plate is attached to the side wall of the car, the length direction of the plate body 100 is parallel to the length direction of the car, and the windward side faces the refrigerant (air cooler). In this way, the second baffle 220 will correspondingly block the sedimentation of the solid phase change material.

[0053] Optionally, the first sub-baffle 210 and the second sub-baffle 220 are cross-connected.

[0054] In this way, the two outermost second sub-baffles 220 along the second direction F2 and the two outermost first sub-baffles 210 along the first direction F1 can be used to form a constrained melting chamber Q11, and then at least two first sub-baffles 210 and at least two second sub-baffles 220 can be well utilized to better limit the flow of the phase change material in the constrained melting chamber Q11, which is beneficial to slow down the melting rate of the phase change material in the constrained melting chamber Q11, and thus help to extend the cooling time, and thus increase the transportation distance of the cold storage cold chain vehicle.

[0055] In some embodiments, the top of the second sub-baffle 220 is connected to the top inner wall of the cold storage chamber Q1 , and the bottom of the second sub-baffle 220 is connected to the bottom inner wall of the cold storage chamber Q1 .

[0056] Optionally, the second sub-baffle 220 is formed integrally with the plate body 100 .

[0057] In this way, the second sub-baffle 220 and the first sub-baffle 210 can be used to enclose the constrained melting chamber Q11, and the second sub-baffle 220 can also be used to support the plate body 100, which can bear part of the pressure on the plate body 100 and improve the structural strength and deformation resistance of the cold storage plate 10.

[0058] It should be noted that the orthographic projection area of ​​the first sub-baffle 210 on the bottom inner wall of the cold storage chamber Q1 is smaller than the area of ​​the bottom inner wall of the cold storage chamber Q1, which can avoid blockage when filling the phase change material into the cold storage chamber Q1 and also reserve a non-constrained melting chamber area.

[0059] In some embodiments, a plurality of first via holes 211 are provided on the first sub-baffle 210, and the first via holes 211 are provided in at least one row or one column. This not only enhances local convective heat transfer but also facilitates the filling of phase change material. The aperture of the first via hole 211 can be set according to the viscosity characteristics of the phase change material and the size of the first sub-baffle 210.

[0060] In some embodiments, a plurality of second via holes 221 are provided on the second sub-baffle 220, and the second via holes 221 are arranged in at least one row or one column. This not only enhances local convective heat transfer, but also facilitates the filling of phase change material. The aperture of the second via hole 221 can be set according to the viscosity characteristics of the phase change material and the size of the second sub-baffle 220.

[0061] In some embodiments, one side of the board body 100 has a windward surface 101, which includes a first side 1011 and a second side 1012 spaced apart along the thickness direction of the board body 100, and the windward surface 101 is constructed to extend in an arc shape from the first side 1011 to the second side 1012.

[0062] Specifically, the board body 100 has a bottom wall 102 , and along the thickness direction of the board body 100 , the first side edge 1011 is closer to the bottom wall 102 than the second side edge 1012 .

[0063] Specifically, the windward surface 101 is disposed toward the refrigerant, and the refrigerant may be cold air output by an air cooler.

[0064] Specifically, the windward surface 101 is located on the left side of the board body 100 .

[0065] In this way, the cold air output by the air cooler can flow along the surface of the board body 100 under the guidance of the windward surface 101, which is conducive to the cold air coming into contact with the board body 100 more quickly, so as to quickly store the cold energy in the phase change material during the peak and valley periods of electricity consumption.

[0066] In some embodiments, the windward surface 101 is constructed as a semicircular arc surface, the diameter of the semicircular arc surface is equal to the height of the plate body 100, the plate body 100 has a bottom wall 102 and a top wall 103 arranged at intervals along the thickness direction of the plate body 100, and the height of the plate body 100 is the distance between the bottom wall 102 and the top wall 103 along the thickness direction of the plate body 100.

[0067] It can be understood that the windward surface 101 can well guide the cold air output by the air cooler to flow toward the top wall 103 and the bottom wall 103 of the plate body 100, so as to quickly store the cold energy in the phase change material.

[0068] In some embodiments, the windward surface 101 is connected between the bottom wall 102 and the top wall 103 , and a plurality of protrusions 104 are disposed on the top wall 103 .

[0069] Specifically, the protrusion 104 is spherical, so that the surface area of ​​the protrusion 104 can be increased, thereby increasing its contact area with the cold air, thereby increasing the effective heat transfer area of ​​the surface of the cold storage plate 10, and the surface of the protrusion 104 can promote the mixing and convective heat transfer of the fluid when the fluid (such as cold air) passes through, effectively destroying the thermal boundary layer, and improving the heat transfer efficiency and uniformity.

[0070] Optionally, the plurality of protrusions 104 are arranged to form a plurality of protrusion groups spaced apart along the third direction F3, the plurality of protrusions 104 of each protrusion group are spaced apart along the second direction F2, and adjacent protrusion groups are staggered along the second direction F2. Of course, the present application is not limited thereto, and each protrusion group may also be arranged in a rectangular, V-shaped or triangular shape. For example, Figure 6 An example is given in which each group of protrusions is arranged in a V shape.

[0071] Specifically, the second direction F2 is parallel to the width direction of the board body 100 , and the third direction F3 is parallel to the length direction of the board body 100 .

[0072] In some embodiments, the protrusion 104 has a supplementary cavity communicating with the cold storage cavity Q1.

[0073] Optionally, the protrusion 104 has a certain thickness and is formed integrally with the plate body 100 .

[0074] The supplementary cavity can be used to fill more phase change material, thereby increasing the cold storage capacity of the cold storage plate 10 .

[0075] In some embodiments, a filling port k communicating with the cold storage chamber Q1 is provided on the board body 100 , and the cold storage board 10 further includes a plugging member 300 for sealing the filling port k, and the plugging member 300 is detachably connected to the portion of the board body 100 where the filling port k is provided.

[0076] The filling port k can be opened on the side wall of the board body 100. For example, the filling port k is arranged on the right side of the board body 100, that is, on the side of the board body 100 away from the windward surface 101. Specifically, a filling nozzle 110 is provided on the side of the board body 100 away from the windward surface 101, and the filling port k is arranged through the filling nozzle 110, and the blocking member 300 is detachably connected to the filling nozzle 110.

[0077] The size of the plugging member 300 matches the size of the filling port k, ensuring good sealing of the plugging member 300 and preventing the safety of cold chain products from being affected by leakage of phase change materials during transportation.

[0078] The plugging member 300 is detachably connected to the portion of the plate body 100 where the filling port k is provided, so as to facilitate filling of the phase change material into the cold storage chamber Q1 . After the filling is completed, the filling port k can be sealed by the plugging member 300 .

[0079] Therefore, the cold storage plate 10 of the present application, since the plate body 100 has two first sub-baffles 210 and two second sub-baffles 220 built in, divides the cold storage chamber Q1 into a constrained melting chamber Q11 mainly based on heat conduction, and an unconstrained melting chamber Q12 coupled by heat conduction and convection heat transfer, so that the cold storage plate 10 constructs two modes of constrained melting and unconstrained melting of phase change materials, realizes different cooling rates, and forms a stepped cooling, thereby reducing the temperature fluctuation in the vehicle, maintaining the warehouse temperature, and extending the cooling time, thereby improving the transportation efficiency of the cold chain vehicle, extending the transportation distance of the cold chain vehicle and improving the temperature uniformity of the cold chain vehicle, and can also solve the problems of short transportation distance, low transportation efficiency, temperature fluctuation, etc. of traditional cold storage cold chain vehicles.

[0080] In addition, since the cold storage plate 10 is provided with a windward surface 101 and a plurality of protrusions 104, the arc-shaped windward surface 101 is suitable for a forced convection heat exchange process in the presence of a wind field, which reduces the collision of air and makes the air flow distribution uniform and smooth, which is conducive to the cold air climbing evenly and stably to the heat exchange surface of the cold storage plate 10 (such as the surface of the plate body 100 on which the plurality of protrusions 104 are provided); the plurality of staggered and spherical protrusions 104 increase the effective heat transfer area of ​​the surface of the cold storage plate 10, and when the fluid passes through the surface of the protrusion 104, eddies and secondary flows are generated, which can promote the mixing and convection heat transfer of the fluid, effectively destroy the thermal boundary layer, and improve the convection heat transfer coefficient, heat transfer efficiency and uniformity. In this way, the windward surface 101 and the plurality of protrusions 104 can be used to accelerate the cold charging rate of the cold storage plate 10.

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0082] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed 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.
