[0042] As Figures 1 to 7 shown, the refrigeration system according to an embodiment of the present utility model includes: a shelf 10 and a plurality of heat exchange mechanisms 60.

[0043] Specifically, the shelf 10 is provided with a plurality of accommodation cavities 13 adapted to accommodate materials. At one end of each accommodation cavity 13 close to the stacker 2, a detachable door panel 15 is provided. At one end of each accommodation cavity 13 away from the stacker 2, a back panel 14 is provided. An air inlet 612 and an air outlet 613 are provided on the back panel 14. A plurality of heat exchange mechanisms 60 are arranged corresponding to the plurality of accommodation cavities 13. Each heat exchange mechanism 60 includes: a housing 61, a heat exchange tube 62, and a fan 63. The housing 61 is disposed on the side of the back panel 14 away from the accommodation cavity 13. The housing 61 and the back panel 14 cooperate to define a heat exchange space 611. The heat exchange space 611 is respectively communicated with the air inlet 612 and the air outlet 613. The heat exchange tube 62 is disposed in the heat exchange space 611 for communicating with an external cooling pipeline. The fan 63 is disposed in the heat exchange space 611 for sucking air from the air inlet 612 to the air outlet 613.

[0044] In other words, the refrigeration system according to the embodiment of the present utility model mainly consists of a shelf 10 and a plurality of heat exchange mechanisms 60. Among them, the shelf 10 is divided into a plurality of accommodation chambers 13, and the plurality of accommodation chambers 13 can be arranged in an array in the vertical plane. The accommodation chamber 13 can be used to accommodate materials, and the materials can include but are not limited to batteries 200. Each accommodation chamber 13 can be a closed heat-insulated space.

[0045] For the convenience of description, the vertical direction can be defined as the first direction, and the second direction and the third direction are perpendicular horizontal directions. The plurality of accommodation chambers 13 on the shelf 10 can be arranged in an array along the first direction and the second direction.

[0046] A stacker 2 can be arranged on one side of the shelf 10, and the stacker 2 can pick up and place materials. The side of the shelf 10 close to the stacker 2 can be defined as the front of the shelf 10, and the side of the shelf 10 far from the stacker 2 can be defined as the back of the shelf 10. A plurality of door panels 15 can be provided on the front of the shelf 10, and the plurality of door panels 15 can be arranged in one-to-one correspondence with the plurality of accommodation chambers 13 for opening or closing the accommodation chambers 13. A plurality of back panels 14 can be provided on the back of the shelf 10, and the plurality of back panels 14 can be arranged in one-to-one correspondence with the plurality of accommodation chambers 13 for sealing the ends of the accommodation chambers 13.

[0047] An air inlet 612 and an air outlet 613 can be provided on the back panel 14, and a heat exchange mechanism 60 can be connected to the side of the back panel 14 far from the accommodation chamber 13. The heat exchange mechanism 60 can mainly consist of a housing 61, a heat exchange tube 62, and a fan 63. Specifically, the back panel 14 can be generally a flat plate structure, and the housing 61 can be recessed toward the side far from the back panel 14 to form a groove. The housing 61 can cover the side of the back panel 14 far from the door panel 15, and the opening of the groove on the housing 61 can face the back panel 14. Thus, the housing 61 and the back can enclose and define a heat exchange space 611.

[0048] In addition, the air inlet 612 and the air outlet 613 are respectively communicated with the heat exchange space 611. The orthographic projection of the heat exchange space 611 on the back panel 14 can respectively coincide with the air inlet 612 and the air outlet 613. A fan 63 and a heat exchange tube 62 can be provided in the heat exchange space 611. The heat exchange tube 62 can be communicated with an external cooling pipeline. The low-temperature coolant can enter the heat exchange tube 62 through the cooling pipeline and flow out after absorbing the heat of the air in the heat exchange space 611. The fan 63 draws air from the air inlet 612 to the air outlet 613, so that the air in the accommodation chamber 13 can enter the heat exchange space 611, thereby performing heat exchange with the coolant in the heat exchange tube 62.

[0049] Therefore, according to the refrigeration system of the embodiment of the utility model, a heat exchange mechanism 60 is arranged on the back plate 14, and a heat exchange space 611 is defined on the side of the back plate 14 away from the accommodating chamber 13 by using the shell 61, which does not occupy the volume of the accommodating chamber 13, is conducive to the access of the battery 200, and avoids the setting of the heat exchange mechanism 60 interfering with the opening and closing of the door plate 15. An air inlet 612 and an air outlet 613 connected to the heat exchange space 611 are arranged on the back plate 14, and the air is extracted from the accommodating chamber 13 in cooperation with the fan 63, so that the air can enter the heat exchange space 611 and perform heat exchange with the coolant in the heat exchange tube 62, and convection is formed between the accommodating chamber 13 and the heat exchange space 611, which has the advantages of simple structure and high heat exchange efficiency.

[0050] According to an embodiment of the present invention, the air inlet 612 is lower than the air outlet 613 .

[0051] Specifically, if Figure 2 and Figure 6 As shown, the air inlet 612 can be located below the air outlet 613. In the accommodating cavity 13, the air temperature above is usually higher than the air temperature below, and the heat will gather at the top of the accommodating cavity 13. Setting the air inlet 612 at a lower position can force the high-temperature air to flow downward into the air inlet 612, and the low-temperature air after heat exchange is discharged from the higher air outlet 613 and mixed with the hot air at a high altitude, which is beneficial to improving the heat exchange efficiency.

[0052] In some specific embodiments, the width of the air inlet 612 in the horizontal direction is the same as the width of the air outlet 613 in the horizontal direction, and the projections of the air inlet 612 and the air outlet 613 in the horizontal plane overlap.

[0053] According to some other embodiments of the present invention, the heat exchange tube 62 includes a plurality of first tubes 621 and a plurality of second tubes 622, the first tubes 621 extend in the horizontal direction, the second tubes 622 are arc-shaped and connected between the ends of two adjacent first tubes 621, and the plurality of first tubes 621 are arranged spaced apart in the vertical direction.

[0054] Specifically, the heat exchange tube 62 may be arranged in a circuitous manner in the heat exchange space 611 to increase the heat exchange area of ​​the heat exchange tube 62. The heat exchange tube 62 may be mainly composed of a plurality of first tubes 621 and a plurality of second tubes 622, the plurality of first tubes 621 may be arranged spaced apart in a first direction, each first tube 621 may extend in a second direction, two adjacent first tubes 621 may be connected by a second tube 622, and the second tube 622 may be an arc-shaped tube, thereby, the plurality of first tubes 621 and the plurality of second tubes 622 may be staggeredly connected to form a circuitous pipeline having a water inlet end and a water outlet end.

[0055] In some other alternative embodiments, two adjacent first tubes 621 may be spaced apart in the third direction, and the second tube 622 may be inclined relative to the horizontal plane and the vertical plane, which is conducive to increasing the number of first tubes 621 in the heat exchange space 611, thereby increasing the heat exchange area of the heat exchange tubes 62 and improving the heat exchange efficiency.

[0056] In some specific embodiments of the present invention, in the horizontal direction, a water inlet and a water outlet (not shown in the figure) are provided at the same end of the housing 61, and the heat exchange tubes 62 communicate with the water inlet and the water outlet.

[0057] Specifically, in the second direction, the water inlet and the water outlet may be provided at the same end of the housing 61 to facilitate the connection of the external cooling pipeline to the water inlet and the water outlet.

[0058] According to some alternative embodiments of the present invention, fins (not shown in the figure) are provided on the outer surface of the heat exchange tubes 62, and the fins are conducive to increasing the heat exchange area of the heat exchange tubes 62, thereby improving the heat exchange efficiency.

[0059] According to some other embodiments of the present invention, the inner wall surface of the heat exchange space 611 includes an inclined surface 614. The bottom end of the inclined surface 614 is connected to the back plate 14, and the orthographic projection of the inclined surface 614 on the back plate 14 coincides with the air inlet 612. In the direction from top to bottom, the inclined surface 614 is inclined towards the back plate 14.

[0060] As Figure 6 shown, the cross-section of the heat exchange space 611 obtained by cutting the heat exchange mechanism 60 and the back plate 14 with a vertical plane parallel to the first direction and the third direction may be in the shape of a right trapezoid. The groove of the housing 61 includes a groove bottom surface, an upper side surface and a lower side surface. Among them, the groove bottom surface may be parallel to the outer surface of the back plate 14, the upper side surface may be parallel to the horizontal plane, and the lower side surface may be formed as the inclined surface 614. The bottom end of the inclined surface 614 may be connected to the outer surface of the back plate 14, and the top end of the inclined surface 614 may extend obliquely upward away from the back plate 14 and be connected to the groove bottom surface.

[0061] In addition, the orthographic projection of the inclined surface 614 on the back plate 14 may coincide with the air inlet 612. Thus, the air entering from the air inlet 612 can flow rapidly upward under the guidance of the inclined surface 614 and contact the heat exchange tubes 62 for heat exchange, which is conducive to improving the heat exchange efficiency.

[0062] In some specific embodiments of the present invention, the fan 63 is columnar, and the axis of the fan 63 extends in the horizontal direction. The fan 63 is arranged above the heat exchange tubes 62, and the orthographic projection of the fan 63 on the back plate 14 coincides with the air outlet 613.

[0063] Specifically, the blower 63 can be a columnar blower. The axis of the blower 63 can extend along the second direction. The orthographic projection of the blower 63 on the back plate 14 can partially or completely coincide with the air outlet 613. That is, the blower 63 can be oppositely arranged with the air outlet 613 in the horizontal direction, so that the air extracted by the blower 63 can quickly enter the accommodation cavity 13 through the air outlet 613, which is beneficial to improving the heat exchange efficiency.

[0064] In addition, by arranging the blower 63 above the heat exchange tube 62, the suction force of the blower 63 can be used to extract air from the accommodation cavity 13, and make the air pass through the heat exchange tube 62 first and exchange heat with the heat exchange tube 62, which is beneficial to optimizing the air flow path and reducing the resistance and disorder of the air flow during the flow process. In addition, the blower 63 being higher than the heat exchange tube 62 can also reduce the accumulation of dust, dirt, etc. on the heat exchange tube 62 to a certain extent, which is beneficial to reducing the workload of maintenance.

[0065] According to some alternative embodiments of the present utility model, the water inlet is provided with an electromagnetic valve, and the refrigeration system further includes a temperature sensor 30 and a controller. The temperature sensor 30 is arranged in the accommodation cavity 13 for detecting the temperature in the accommodation cavity 13. The controller is connected to the temperature sensor 30 and the electromagnetic valve for controlling the opening and closing of the electromagnetic valve according to the detection result of the temperature sensor 30.

[0066] Specifically, a temperature sensor 30 can be arranged in each accommodation cavity 13. The temperature sensor 30 can detect the temperature in the current accommodation cavity 13 and send the detection result to the controller, and the controller can be arranged outside the accommodation cavity 13.

[0067] The controller can control the heat exchange mechanism 60 to work or stop working according to the temperature detection result to realize the feedback control of heat exchange, so as to control the temperature of the accommodation cavity 13 within a preset temperature range, which is beneficial to reducing the temperature difference between the actual temperature and the preset temperature.

[0068] The electromagnetic valve can be arranged at the water inlet. Thus, the controller can control the opening and closing of the electromagnetic valve according to the temperature detection result, thereby controlling the opening and closing of the water inlet to start or stop heat exchange, and further realizing the adjustment of temperature. The controller can also be connected to the blower 63 for controlling the start and stop of the blower 63.

A plurality of shelves 11 are arranged on each frame 18 at intervals in the vertical direction. Two side plates 12 are connected between two adjacent shelves 11.
