[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1and Figure 2 As shown, the utility model discloses a phase change material rack for use in a cold storage. The phase change material rack includes at least two sealing member fixing plates 1, each of which is provided with a sealing member 2 detachably connected to the sealing member fixing plate 1, and a phase change material is provided in the sealing member 2. Specifically, the detachable connection method can be to set a threaded hole on the sealing member 2, set a fixing hole on the fixing plate 1, and connect the bolt to the threaded hole by passing the bolt through the fixing hole, so as to achieve the detachable connection between the sealing member 2 and the fixing plate 1. In this embodiment, the phase change material is a matrix of NaCL aqueous solution, and is mixed with a nucleating agent SiO2, a thickener CMC and a thermal conductivity enhancing material graphite in a certain proportion. In other embodiments, the phase change material can also be water. In other embodiments, the phase change material is provided with a plurality of types, and the components of the various phase change materials are different. The phase change point of the phase change material can be determined according to the temperature required for the refrigerated and frozen storage of goods in the cold storage. According to the different temperatures required for the refrigerated and frozen storage of goods, the phase change materials with different components can be replaced.

[0030] like Figures 3 to 5 As shown, each adjacent sealing fixing plate 1 is connected by a telescopic component, and each sealing fixing plate 1 is connected to the telescopic component to form a telescopic mechanism, and the two ends of the telescopic mechanism along the telescopic direction of the telescopic mechanism are respectively connected with a fixing mechanism, and the fixing mechanism is connected to the telescopic mechanism through the telescopic component, and the fixing mechanism is used to be fixed to the shelf 3 in the cold storage.

[0031] like Figure 5 As shown, during the use of the phase change material hanger of the utility model, due to the setting of the telescopic component, the length of the phase change material hanger can be extended, so the phase change material hanger can be hung on the shelves 3 of different sizes in the cold storage. And because the seal fixing plate 1 and the seal 2 are detachably connected, the number of the seals 2 on the phase change material hanger can be calculated according to the number of goods stored on the shelves 3 in the cold storage. When the number of goods stored on the shelves 3 is small, the bolts are removed from the threaded holes to realize the removal of the seal 2 from the seal fixing plate 1.

[0032] like Figure 5As shown, the utility model also discloses a cold storage, which includes a closed cold storage room 4, a refrigeration unit 5 for refrigerating the closed cold storage room 4, and the cold storage also includes the shelf 3 arranged in the closed cold storage room 4. The cold storage also includes a control unit, a temperature sensor and the phase change material rack, the phase change material rack is fixed on the shelf 3, the temperature sensor is arranged in the closed cold storage room 4, the refrigeration unit 5 and the temperature sensor are electrically connected to the control unit, and the control unit can control the refrigeration unit 5 to work according to the information of the temperature sensor.

[0033] During the use of the cold storage of the utility model, the goods to be frozen and refrigerated are placed on the shelf 3 located in the closed refrigerating chamber 4, and the number of the seals 2 is adjusted according to the number of goods to be frozen and refrigerated. Finally, the phase change material rack after the number of seals 2 is adjusted is fixed on the shelf 3. Specifically, the phase change material rack is fixed above the goods to be frozen and refrigerated. After the phase change material releases cold air, the cold air sinks to refrigerate the goods to be frozen and refrigerated. If the goods to be frozen and refrigerated are placed in the cold storage during the day, the phase change material in the seal 2 must have stored cold energy and can be refrigerated immediately. If the goods to be frozen and refrigerated are placed in the cold storage at night, the phase change material in the seal 2 must not store cold energy; at the same time, the refrigeration unit 5 works to refrigerate, and the goods to be frozen and refrigerated and the phase change material in the seal 2 both absorb cold energy. At this time, since it is night, the electricity price is at the valley price, so the electricity cost consumed by the refrigeration unit 5 is relatively low. During the day, since the electricity price is at peak time, the refrigeration unit 5 is turned off, and the phase change material in the seal 2 cools the goods to maintain the temperature in the cold storage. When the door of the cold storage is often opened during the day to store goods, the cold air in the closed cold storage room 4 is lost, and the temperature sensor transmits the detected temperature in the closed cold storage room 4 to the control unit, and the control unit determines whether the temperature in the closed cold storage room 4 is too high. If the control unit determines that the temperature of the closed cold storage room 4 is higher than the phase change temperature of the phase change material, the control unit controls the refrigeration unit 5 to work for cooling to ensure the temperature of the closed cold storage room 4.

[0034] The utility model provides a phase change material in the seal 2. When the phase change material rack is fixed in the cold storage, the seal 2 can be cooled at night, so that the phase change material in the seal 2 absorbs cold energy. The refrigeration unit 5 of the cold storage is turned off during the day, and the phase change material is used for refrigeration. Since the electricity price at night is at the off-peak price, the operation cost of the cold storage can be effectively reduced. The utility model provides a detachable seal 2 on the seal fixing plate 1, so that the number of seals 2 can be set according to the number of goods stored on the shelves 3 in the cold storage, so as to avoid excessive energy consumption of the refrigeration unit when the seal is cooled at night due to too many seals 2. And by providing the telescopic mechanism, it is convenient for the phase change material rack to be hung on the shelves 3 of different sizes.

[0035] Meanwhile, in the cold storage without the seal 2, the refrigeration unit 5 is prone to frost accumulation at the evaporator outlet due to continuous operation, so the refrigeration unit 5 needs to be shut down at regular intervals to defrost the evaporator of the refrigeration unit 5. The utility model reduces the working time of the refrigeration unit 5 by using the phase change material, and can appropriately reduce the frequency of shutting down the refrigeration unit 5 for defrosting.

[0036] In this embodiment, a defrost temperature sensor is installed in the evaporator fin of the refrigeration unit 5, and the temperature signal detected by the defrost temperature sensor can be transmitted to the control unit, so that the control unit determines whether the refrigeration unit 5 needs to be stopped for defrosting operation in combination with the temperature of the closed refrigeration chamber 4. When the defrosting operation is performed, the refrigeration unit 5 adopts the defrosting type of hot fluorine defrosting.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the telescopic components are connected to each other to form a telescopic assembly. Therefore, when the fixing mechanism is pulled to make the phase change material hanger telescope, the distance between the adjacent sealing components 2 can be expanded or reduced at the same time, which is convenient for operation. In other embodiments, the telescopic components may not be connected. Therefore, the distance between the adjacent sealing components 2 can be adjusted separately.

[0038] like Figures 1 to 4As shown, in this embodiment, the telescopic component is a scissor arm 6. The scissor arm 6 includes a cross arm 6a and two telescopic connectors 6b. The two telescopic connectors 6b are respectively a first telescopic connector and a second telescopic connector. The cross arm 6a is composed of two identical connecting arms, and the centers of the two connecting arms are rotatably connected. The first telescopic connector and the second telescopic connector are both provided with a sliding groove 6ba and a rotating hole 6bb. One end of one of the connecting arms slides in the sliding groove 6ba on the first telescopic connector, and the other end of one of the connecting arms is rotatably connected to the rotating hole 6bb on the second telescopic connector. One end of the other connecting arm is rotatably connected to the rotating hole 6bb on the first telescopic connector, and the other end of the other connecting arm slides in the sliding groove 6ba on the second telescopic connector. At the same time, two adjacent cross arms 6a are connected to each other. In other embodiments, the telescopic component can also be a spring or a telescopic rod or a cylinder.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the seal fixing plate 1 and the fixing mechanism are both provided with the telescopic components, and each of the telescopic components is parallel to each other. Specifically, the seal fixing plate 1 and the fixing mechanism are both provided with telescopic connectors 6b, the two telescopic connectors 6b located on each seal fixing plate 1 are parallel to each other, and the two telescopic connectors 6b located on each fixing mechanism are parallel to each other. The utility model provides the telescopic components on both sides of the seal fixing plate 1 and the fixing mechanism, so that the phase change material hanger can be stably telescoped.

[0040] like Figures 4 to 6 As shown, the fixing mechanism includes a support plate 7 connected to the telescopic component, and the support plate 7 is used to be fixed to the shelf 3. In this embodiment, when the phase change material rack needs to be fixed on the shelf 3, the support plate 7 can be placed on the upper end of the crossbeam of the shelf 3. In other embodiments, a slot for inserting the support plate 7 can be provided on the shelf 3, and when the phase change material rack needs to be fixed on the shelf 3, the support plate 7 can be inserted into the slot.

[0041] like Figures 3 to 6 As shown, in this embodiment, the support plate 7 is connected with an anti-slip plate 8, and the anti-slip plate 8 is arranged perpendicular to the support plate 7. The support plate 7 is provided with the telescopic connector 6b, and the telescopic connector 6b, the support plate 7 and the anti-slip plate 8 are sequentially connected to form an inverted U shape, and the fixing mechanism can be hung on an external shelf. The utility model enables the phase change material rack to be stably hung on the shelf 3 through the arrangement of the anti-slip plate 8.

[0042] like Figure 2 and Figure 5 As shown, in this embodiment, the seal 2 is in the shape of a thin plate, and the cavity in the seal 2 for accommodating the phase change material is also in the shape of a thin plate, and when the phase change material rack is hung on the shelf 3, the side surface of the seal 2 with a smaller area faces the air outlet of the refrigeration unit 5. The utility model increases the contact area between the refrigeration air of the refrigeration unit 5 and the seal 2 by setting the seal 2 in the shape of a thin plate, and at the same time, when the phase change material in the seal 2 is refrigerated, the refrigeration area can be larger.

[0043] like Figure 3 In the present embodiment, the phase change material rack further includes a fan mechanism 9, and the air supply direction of the fan mechanism 9 is arranged toward the sealing member 2. Specifically, the fan mechanism 9 includes a fan assembly, a battery, a sensing component and a fan control component, and the fan assembly, the battery, the sensing component and the fan control component are electrically connected to each other. The fan mechanism 9 is fixed on the sealing member 2. When the phase change material in the sealing member 2 starts to cool, the control unit sends a signal to the sensing component to generate a fan operation, the fan control component controls the operation of the fan assembly, the battery supplies power to the fan assembly, and the fan assembly diffuses the cold air emitted by the phase change material. The utility model facilitates the diffusion of the cold air emitted by the phase change material by setting the fan mechanism 9.

[0044] like Figure 3 In the present embodiment, the fan mechanism 9 is arranged below the seal 2. When the fixing mechanism is hung on the shelf 3, the air supply direction of the fan mechanism 9 is vertically upward. When the phase change material in the seal 2 is refrigerated, the cold air flows downward, and under the action of the fan mechanism 9, the cold air can flow upward, so that the cold air is transmitted to every corner of the closed refrigeration chamber 4, thereby improving the energy efficiency and temperature stability of the cold storage. The utility model facilitates the transmission of cold air to every corner of the closed refrigeration chamber 4 by arranging the fan mechanism 9 below the seal 2.

[0045] In summary, the utility model provides a phase change material in the seal 2. When the phase change material rack is fixed in the cold storage, the seal 2 can be cooled at night, so that the phase change material in the seal 2 absorbs cold. The refrigeration unit 5 of the cold storage is turned off during the day, and the phase change material is used for refrigeration. Since the electricity price at night is at the off-peak price, the operating cost of the cold storage can be effectively reduced. And by providing a detachable seal 2 on the seal fixing plate 1, the number of seals 2 can be set according to the number of goods stored on the shelf 3 in the cold storage, so as to avoid the situation where the energy consumption of the refrigeration unit is too large when the seal is cooled at night due to too many seals 2. And by providing the telescopic mechanism, it is convenient for the phase change material rack to be hung on the shelves 3 of different sizes. And by providing the telescopic components on both sides of the seal fixing plate 1 and the fixing mechanism, the phase change material rack can be stably telescoped. By setting the anti-slip plate 8, the phase change material rack can be stably hung on the shelf 3. By setting the seal 2 in a thin plate shape, the contact area between the refrigeration wind of the refrigeration unit 5 and the seal 2 is increased. At the same time, when the phase change material in the seal 2 is refrigerated, the refrigeration area can be larger. By setting the fan mechanism 9, the cold air emitted by the phase change material can be diffused. By setting the fan mechanism 9 below the seal 2, the cold air can be transmitted to every corner of the closed refrigeration chamber 4.

[0046] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
