Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat exchange equipment, and in particular to a cold storage with a phase change cold storage module. BACKGROUND

[0002] In the storage scene of medicine, fresh food and other needs of low temperature environment, the cold storage box module is often used as an auxiliary or emergency cold source to maintain the temperature stability of the shelf area. The cold storage box module is composed of a plurality of cold storage boxes arranged side by side. The cold storage box is composed of a plastic shell and a phase change cold storage material packaged inside. When the external refrigeration system is running, the cold quantity is conducted to the cold storage box, and the phase change material in the shell condenses and stores cold. When the cold quantity needs to be released, the phase change material melts and absorbs heat, and the heat exchange between the box surface and the air realizes continuous cooling.

[0003] At present, the mainstream scheme of integrating the cold storage box module in the shelf system mainly includes the following two kinds: shelf top installation (directly placing or fixing the cold storage box module on the top beam or top plate of the shelf structure); shelf interlayer installation (placing the cold storage box module on the bearing crossbeam of each layer of the shelf), such as the cold storage shelf recorded in reference document 1.

[0004] Reference document 1: Chinese patent document with publication number CN218781494U.

[0005] Reference document 1 records a cold storage shelf, which includes a vertical support and a cold storage module. The vertical support includes a plurality of storage units arranged from bottom to top. The storage space for placing goods is formed between adjacent storage units. The cold storage module is arranged on the top of each layer of storage units. The cold storage module includes a plurality of cold storage ice boxes with sealed chambers arranged at intervals. The phase change cold storage agent is filled in the sealed chamber. A plurality of flow guides are arranged on the outside of the cold storage ice box. The flow guides are horizontally extended from the edge of at least one side wall of the cold storage ice box and gradually extended to the direction of the storage space at the bottom. The cold air flow channel is formed between adjacent flow guides, or the flow guide is the cold air flow channel. By placing the cold storage module on the top of each layer of storage units, the cold air in the cold storage is guided to the storage space through the flow guides when the cold air passes through the cold storage module, so that the cooling effect is better, the electricity cost is reduced, and energy saving and emission reduction are realized.

[0006] The cold storage box module is installed on the top of the shelf. Although the top space is utilized, the cold quantity sinking efficiency may be limited, and the top space is limited, and it is difficult to arrange a sufficient number of cold storage units to meet the large area or high cold quantity demand. The cold storage box module is installed between the layers of the shelf. Although it is closer to part of the goods compared with the top installation, the module itself blocks the airflow flow in the horizontal direction between the layers, causing local airflow dead angle and temperature unevenness, and the installation and maintenance work is not convenient, and the goods stacked on the layer shelf need to be removed to install and maintain the cold storage box module.

[0066] For a better understanding of the present application, the same will be described in connection with the following examples, which are not intended to limit the scope of the application.

[0067] Example 1

[0068] As shown in Figure 1 and 2 : a cold storage with phase change cold storage module, comprising a refrigeration device, a shelf and a cold storage module arranged in the cold storage for storing cold energy generated by the refrigeration device, the shelf comprises a plurality of independent shelves 1 distributed along both sides of the aisle, the independent shelf 1 comprises a three-dimensional frame and a layer plate 101 arranged on the three-dimensional frame from top to bottom, and the three-dimensional frame is assembled by a plurality of columns 102 and horizontal beams 103.

[0069] The core function of the refrigeration device is to systematically absorb the heat inside the cold storage and discharge it to the external environment through the refrigeration cycle system, so as to realize and maintain the set low temperature environment. Its technical principle is mainly based on the physical state change and heat transfer of refrigerant (refrigerant). The whole system continuously circulates the compression, condensation, throttling and evaporation process through the synergistic action of four components (compressor, condenser, expansion valve / throttling device and evaporator), continuously "pumping" the heat in the cold storage to the external environment, so as to protect the low temperature of the cold storage.

[0070] Two independent shelves 1 located in the same row on both sides of the aisle are provided with a cold storage module 3 through a connecting piece 2, and the cold storage module 3 is located above the aisle.

[0071] The connecting piece 2 is installed at the top of the column 102 of the independent shelf 1, one of the support cross beams 301 of the cold storage box module is erected between the two connecting pieces 2 of the shelf on one side, and the other support cross beam 301 of the cold storage box module is erected between the two connecting pieces 2 of the shelf on the other side, and the air flow direction of the cold storage box module is consistent with the direction of the aisle.

[0072] <cold storage box module>

[0073] As shown in Figures 3-9 : the cold storage box module comprises two support cross beams 301 and a plurality of cold storage units arranged between the two support cross beams 301, the cold storage unit comprises two fixed rods 302 arranged in parallel and a plurality of phase change cold storage boxes 303 arranged on the two fixed rods 302, and the two ends of the fixed rod 302 are connected to the two support cross beams 301 respectively.

[0074] Specifically, the fixed rod 302 is connected with the support beam 301 through a hook 304, the hook 304 is composed of a U-shaped buckle 3041 and a sleeve 3042 arranged on one side outer wall of the U-shaped buckle 3041, the U-shaped buckle 3041 of the hook 304 can be hung on the support beam 301, and the end of the fixed rod 302 can be inserted into the sleeve 3042 of the hook 304.

[0075] The phase change cold storage box 303 comprises a cold storage box body 3031 and a phase change cold storage material filled in the cold storage box body 3031, the cold storage box body 3031 is a flat rectangular cuboid structure, and has two mutually parallel rectangular main planes and four rectangular side vertical planes connecting the main planes.

[0076] The cold storage box body 3031 has two hanging holes 3032 penetrating the main planes and being isolated from the internal cavities, and two protruding support heads 3033 are arranged on the two main planes of the cold storage box body 3031 respectively, and the two support heads 3033 are located between the two hanging holes 3032.

[0077] The two main planes of the cold storage box body 3031 are respectively provided with two protruding support heads 3033, and the support heads 3033 are in the shape of a circular truncated cone. The two support heads 3033 are located between the two hanging holes 3032. The specific structure of the support head 3033 can have two forms, the first form: the support head 3033 is integrally formed with the cold storage box body 3031. The second form: the support head 3033 is detachably connected to the cold storage box body 3031. Specifically, the main plane of the cold storage box body 3031 is provided with a mounting groove, the mounting groove has an internal thread, and the lower part of the support head 3033 can be screwed into the mounting groove.

[0078] When the cold storage boxes are hung side by side, the corresponding support heads on the adjacent boxes abut against each other, like built-in "limiting devices", and automatically and reliably form uniform air gaps between the boxes. The formed gaps become the channels for natural convection of cold air (or hot air when charging cold), greatly improving the air flow circulation between the boxes and avoiding the decrease of heat exchange efficiency caused by close contact (i.e. "thermal short circuit" phenomenon). At the same time, the enhanced air flow ensures that the phase change material exchanges heat with the surrounding environment (cold air) more quickly and uniformly during the charging cold (solidification heat release) and releasing cold (melting heat absorption) processes, shortens the charging cold time and prolongs the releasing cold duration.

[0079] The cold storage box body 3031 is also provided with a filling port 3035, and the filling port 3035 is located on one side vertical plane with a smaller area. The side vertical plane has a recess, and the filling port 3035 is arranged in the recess.

[0080] Two avoiding grooves 3034 are respectively arranged on two main planes of the cold storage box body 3031, and the two avoiding grooves 3034 are located between the two support heads 3033. The support head 3033 is a circular truncated cone structure. The hanging hole 3032 on the cold storage box body 3031 is a circular through hole, and the diameter of the hanging hole 3032 is greater than the diameter of the bottom surface of the support head 3033. The center points of the hanging hole 3032, the support head 3033 and the avoiding groove 3034 are located in the same plane, and the plane is perpendicular to the main plane of the cold storage box body 3031 and parallel to the long side vertical plane of the cold storage box body 3031, and the distance between the two support heads 3033 is L1, and the distance between one of the avoiding grooves 3034 and the hanging hole 3032 away from the avoiding groove 3034 is L2, and L1 is equal to L2.

[0081] Through the above structural design, when stacked, the support head on the bottom surface of the upper cold storage box can be accurately embedded in the corresponding avoiding groove and hanging hole on the top surface of the lower cold storage box, and at the same time, the support head on the top surface of the lower cold storage box can also be embedded in the corresponding structure on the bottom surface of the upper cold storage box. This "concave-convex interlocking" mechanism is like built-in stacking guide rails. The nested cooperation of the support head and the hanging hole / avoiding groove effectively prevents horizontal sliding and misalignment between the boxes during transportation or storage, greatly improving the stability and safety of the stacking. The nested stacking significantly reduces the stacking height, avoids the waste of additional space caused by the protruding support head, and maximizes the use of transportation vehicles or storage space. At the same time, the avoiding groove provides a dedicated accommodation space for the support head, avoiding deformation or damage caused by mutual extrusion or hard contact with the lower box during stacking. The functional components (hanging hole, support head) of the cold storage box itself are transformed into an efficient stacking positioning system in cooperation with the newly added avoiding groove, which perfectly solves the efficient, stable and space-saving stacking problem of the cold storage box with a protruding support head in the non-working state (transportation, storage) without affecting the core structure of the cold storage function.

[0082] A plurality of "capsule-shaped" grooves 3036 are also arranged on the main plane of the cold storage box body 3031. The main function of these grooves 3036 is to increase the surface area of the cold storage box. These specially shaped grooves significantly increase the effective contact surface area of the cold storage box with the surrounding cold / hot air. The groove structure disturbs the laminar flow of air flowing over the surface of the box, breaks the static air boundary layer (thermal resistance layer) that hinders heat exchange, and promotes the generation of micro-vortex flow in the grooves, thereby greatly enhancing the convective heat transfer efficiency.
