[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] Please also read Figure 1 and Figure 2Now, the cold storage device 6 provided by the utility model is described. The cold storage device 6 includes a frame 1 and a plurality of detachable cold storage tubes 2.

[0049] The skeleton 1 is provided with a plurality of installation channels distributed in an array, each of which passes through the skeleton 1 along the front-to-back direction of the skeleton 1; each detachable cold storage tube 2 is correspondingly inserted into one of the installation channels and can be pulled out from the installation channel.

[0050] Specifically, a plurality of installation channel rectangular arrays are arranged on the skeleton 1 to facilitate the installation of more detachable cold storage tubes 2 on the skeleton 1. In addition, the detachable cold storage tube 2 can also be set to a plate shape, or other shapes, and the shape of the detachable cold storage tube 2 is not limited here. Compared with detachable cold storage tubes 2 of other shapes, the tubular detachable cold storage tube 2 has fewer edges and corners, which is more convenient to insert and pull into the installation channel, thereby improving the disassembly speed of the detachable cold storage tube 2. The detachable cold storage tube 2 is filled with phase change material, and the outer shell material is 1 mm high-density polyethylene. The skeleton 1 is made of aluminum alloy, which can ensure the corrosion resistance of the skeleton 1 and make the overall weight of the skeleton 1 lighter, which is convenient for carrying.

[0051] Compared with the prior art, the cold storage device 6 provided by the utility model is characterized in that a plurality of detachable cold storage tubes 2 are arranged on the frame 1, so that the detachable cold storage tubes 2 can be replaced in time when the cold capacity inside is insufficient, thereby achieving the effect of timely replenishing cold, and thus ensuring sufficient cold capacity in the carriage 4; and in view of the problem that the cold capacity consumption of the detachable cold storage tubes 2 at different parts is different, the position of the detachable cold storage tubes 2 with a larger cold capacity consumption and the detachable cold storage tubes 2 with a smaller cold capacity consumption can be swapped, thereby improving the flexibility of the cold storage device 6, avoiding the problem of temperature out of control in the carriage 4, and making full use of the cold energy in the cold storage device 6.

[0052] In some embodiments, the skeleton 1 may be used as follows: Figures 2 to 4 See the structure shown. Figures 2 to 4 The skeleton 1 includes a rectangular frame body 11 and a plurality of supporting beams.

[0053] The rectangular frame body 11 is a hexahedral frame structure; multiple groups of support beams are spaced apart along the left-right direction of the skeleton 1; each group of support beams is extended along the up-down direction of the skeleton 1, and the upper end of each group of support beams is connected to the inner top wall of the rectangular frame body 11, and the lower end is connected to the inner bottom wall of the rectangular frame body 11; each group of support beams is provided with multiple installation channels, and the multiple installation channels on each group of support beams are spaced apart along the up-down direction of the skeleton 1.

[0054] On the one hand, the support beam supports the rectangular frame 11, making the structure of the rectangular frame 11 more stable; on the other hand, the support beams spaced apart along the left and right directions of the skeleton 1 facilitate reasonable planning of the number of installation channels, and facilitate confirmation of the approximate range of the detachable cold storage tubes 2 of the part with less energy consumption or the part with more energy consumption.

[0055] In some embodiments, the support beam is Figures 5 and 6 See the structure shown. Figures 2 to 4 Each group of supporting beams includes a plurality of supporting plates 12 .

[0056] A plurality of support plates 12 are spaced apart along the front-to-back direction of the frame 1; each support plate 12 is extended along the up-down direction of the frame 1, and a surface of each support plate 12 is perpendicular to the front-to-back direction of the frame 1; each support plate 12 is provided with a plurality of mounting holes 121 spaced apart along the up-and-down direction of the frame 1; wherein a plurality of mounting holes 121 with colinear axes form a mounting channel.

[0057] Specifically, the support sheet 12 is in the shape of a long strip, and its long side extends in the vertical direction of the frame 1. There is a ventilation gap 423 between two adjacent support sheets 12 along the front-to-back direction of the frame 1, and the ventilation gap 423 penetrates the frame 1 in the vertical direction, so that the cold air in the cold storage device 6 can flow more smoothly. The support sheet 12 also has the function of transferring cold energy. Under the interaction with the ventilation gap 423, the cold energy of the detachable cold storage tube 2 with less energy consumption can be transferred to the detachable cold storage tube 2 with more energy consumption, so that the cold energy of each part of the cold storage device 6 tends to be balanced. The number of multiple support sheets 12 in each group of support beams can be adjusted automatically, and it is best when the number of support sheets 12 in each group of support beams is set to five.

[0058] In some embodiments, the cold storage device 6 is as follows: Figures 2 to 4 See the structure shown. Figures 2 to 4 The cold storage device 6 also includes a plurality of fixed cold storage tubes 3.

[0059] A plurality of fixed cold storage tubes 3 are fixedly arranged on the frame 1 in an array; each fixed cold storage tube 3 is extended along the front-to-back direction of the frame 1; each fixed cold storage tube 3 is correspondingly fixedly inserted into one of the installation channels.

[0060] The fixed cold storage tube 3 can be arranged between the detachable cold storage tubes, and the fixed cold storage tube 3 has the function of temporarily storing cold energy; when the detachable cold storage tube 2 that is full of cold energy is reinstalled, the cold energy in the detachable cold storage tube 2 will be continuously transferred to the fixed cold storage tube 3, so that the cold energy in the cold storage device 6 will continue to flow, thereby increasing the circulation speed of the cold energy.

[0061] In some embodiments, the fixed cold storage tube 3 is adopted as follows Figures 2 to 4 See the structure shown. Figures 2 to 4 , multiple fixed cold storage tubes 3 are distributed in a rectangular array, multiple detachable cold storage tubes 2 are also distributed in a rectangular array, and multiple rows of detachable cold storage tubes 2 are distributed between every two adjacent rows of fixed cold storage tubes 3; or, multiple fixed cold storage tubes 3 are distributed in a circular array, multiple detachable cold storage tubes 2 are also distributed in a circular array, and multiple circles of detachable cold storage tubes 2 are distributed between every two adjacent circles of fixed cold storage tubes 3.

[0062] By arranging the fixed cold storage tube 3 and the detachable cold storage tube 2 in a regular manner, it is convenient to confirm the positions of the fixed cold storage tube 3 and the detachable cold storage tube 2. When the cold storage device 6 is working, the cold is transferred from the bottom to the top. However, the fixed cold storage tube 3 and the detachable cold storage tube 2 are arranged in layers along the vertical direction of the frame 1, and the cold in the detachable cold storage tube 2 is continuously transferred to the fixed cold storage tube 3. Therefore, the cold in the frame 1 has already circulated in the vertical direction before working, resulting in a faster transfer rate of cold in the vertical direction when the cold storage device 6 starts working, thereby improving the startup speed of the cold storage device 6.

[0063] In some embodiments, the fixed cold storage tube 3 is adopted as follows Figures 2 to 4 See the structure shown. Figures 2 to 4 The inner cavity of each fixed cold storage tube 3 is provided with a fixing column 31, which extends along the front-to-back direction of the frame 1, and the front end of the fixing column 31 is fixedly connected to the inner front wall of the rectangular frame body 11, and the rear end is fixedly connected to the inner rear wall of the rectangular frame body 11.

[0064] Specifically, the inner front wall and the inner rear wall of the frame 1 are provided with fixing holes corresponding to the fixing columns 31, and the two ends of the fixing columns 31 are respectively inserted into two fixing holes arranged opposite to each other, so as to fix the cold storage tube 3 on the frame 1. The fixing method is simple and convenient, and prevents too many parts from affecting the cold transmission effect.

[0065] Based on the same inventive concept, please refer to Figure 1 , Figure 10 to Figure 11 The embodiment of the present application also provides a cold storage type electric refrigerated vehicle, including a compartment 4 and a partition 41.

[0066] A partition 41 is provided in the carriage 4, the partition 41 is close to the front wall of the carriage 4, and the partition 41 divides the inner cavity of the carriage 4 into a first chamber 42 and a second chamber 43; the cold storage device 6 is located in the first chamber 42; wherein, a plurality of detachable cold storage tubes 2 are extended along the front and rear directions of the carriage 4.

[0067] Specifically, the cold storage device 6 can be directly placed in the first chamber 42; a switch door is provided on the right side wall of the first chamber 42, and the cold storage device 6 is placed into the first chamber 42 through the switch door. The setting of the switch door is also convenient for periodic maintenance of the cold storage device 6 to prevent the cold storage device 6 from being damaged during transportation; a cold station 5 can be set up in the transportation route of the cold storage electric refrigerated truck. After the cold capacity in the detachable cold storage tube 2 is consumed, the cold storage device 6 is taken out from the switch door, and the cold storage device 6 full of cold capacity is replaced from the cold station 5.

[0068] In a possible implementation, the cold storage electric refrigerated vehicle can be Figures 9 to 11 See the structure shown. Figures 8 to 11 A cold air return port 414 is provided at the top of the side wall of the first chamber 42 ; a cold air inlet 413 is provided at the bottom of the side wall of the first chamber 42 .

[0069] Specifically, the cold air return port 414 and the cold air inlet port 413 are both opened on the left side of the vehicle body. After the frame 1 is placed in the first chamber 42, a cold air inlet cavity 421 is provided between its bottom wall and the bottom wall of the first chamber 42, and a cold air return cavity 422 is provided between the top wall of the frame 1 and the top wall of the first chamber 42. The cold air inlet port 413 and the cold air return port 414 are connected to the cold air inlet cavity 421 and the cold air return cavity 422, respectively.

[0070] When the cold capacity in the detachable cold storage tube 2 is consumed, the cold capacity can be replenished in the cold station 5; the cold station 5 is provided with a cold charging source, which is connected to the cold charging air inlet 413 and the cold charging return air outlet 414 of the cold storage electric refrigeration vehicle through two air ducts 51 respectively, and the cold air in the cold charging source enters the cold charging air inlet chamber 421 from the cold charging air inlet 413. The cold charging air inlet chamber 421 has the function of buffering the cold air, so that the cold air is completely in contact with the detachable cold storage tube 2 under the skeleton 1, and the cold air is transmitted from bottom to top and finally transmitted to the cold charging return air chamber 422. The cold charging return air chamber 422 also has the function of buffering, so that the cold air stays in the first chamber 42 for a longer time, and finally the cold air flows into the cold charging source from the cold charging return air outlet 414. Under the continuous circulation of the cold air in the first chamber 42, the cold capacity in the detachable cold storage tube 2 is filled. A blower is also provided in the cold station 5 , and two ends of the blower are respectively connected to the cold air inlet cavity 421 and the cold source, so as to accelerate the transfer efficiency of the cold air in the cold source to the first chamber 42 .

[0071] In a possible implementation, the partition 41 may be formed as follows: Figures 7 and 8 See the structure shown. Figures 7 and 8 An opening and closing air vent 411 is provided at the bottom of the partition 41 , and the opening and closing air vent 411 is used to connect the first chamber 42 and the carriage 4 ; a plurality of fans 412 are provided at the top of the partition 41 .

[0072] Specifically, the fans 412 are evenly distributed along the left and right directions of the carriage 4, and the fans 412 can continuously pump the coldness in the first chamber 42 into the second chamber 43, thereby accelerating the temperature change speed in the second chamber 43. When the temperature in the second chamber 43 is high, the speed of the fans 412 can be increased, and the open-closed air vents 411 can be opened to allow the heat in the second chamber 43 to flow into the first chamber 42. When the temperature in the second chamber 43 is too low, the open-closed air vents 411 can be closed, and the speed of the fans 412 can be reduced to continuously maintain the temperature in the second chamber 43 in a stable state.

[0073] In a possible implementation, the cold storage electric refrigerated vehicle can be Figure 8 See the structure shown. Figure 8 The cold storage electric refrigerated vehicle also includes an air guide louver 44 and a plurality of cold capacity sensors.

[0074] The wind guide louver 44 is arranged on the top of the first chamber 42; a plurality of cooling sensors are respectively arranged on the frame 1 and arranged at intervals along the left and right directions of the carriage 4, for detecting the cooling capacity in the detachable cold storage pipe 2.

[0075] The wind guide louver 44 is located above the frame 1, and the length direction of the window leaf of the wind guide louver 44 is the front-to-back direction of the frame 1. Multiple cold sensors detect the amount of cold in different areas respectively. A central control module is also provided on the carriage 4, and the central control module is electrically connected to the wind guide louver 44 and the cold sensor. The cold sensor transmits the temperature to the central control module in the form of an electrical signal. When it is detected that the cold amount of the detachable cold storage pipe 2 in a part of the area is large, the central control module controls the wind guide louver 44 to adjust the direction of its window leafs so that the channel between the window leafs faces the area with large cold amount, so as to balance the cold amount of each part in the cold storage device 6. In order to prevent the drawings from being disordered, the central control module and the cold sensor are not drawn in the figure.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
