[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The cold storage box provided by the present invention divides the cold storage bags into several parts, each cold storage bag is in full contact with the fin assembly, and the fin assembly arranged inside the box can increase the effective heat exchange area with the cold storage bag, and the fin assembly can perform more sufficient heat exchange with the cold storage medium in the cold storage bag.

[0034] 2. The cold storage box provided by the present invention has a cooling member sealed on the box body, one end of which is in contact with the connecting plate of the fin assembly, and the other end of which extends from the box body and exchanges heat with the cooling assembly. The cold of the cold storage medium in the cold storage bag can be transferred to the connecting plate, and then to the cooling member, and then the cold can be transferred to the cooling assembly through the cooling member, and the cold can be discharged through the cooling assembly; and a cooling pipeline can also be provided inside the fin assembly, and the end of the cooling pipeline extends from the fin assembly and exchanges heat with the cooling assembly. The present invention can choose to connect the cooling pipeline or the cooling member with the cooling assembly according to the situation.

[0035] 3. In the cold storage box provided by the present invention, a cold storage medium holding chamber is formed between every two adjacent fins, and at least one cold storage bag is held in each cold storage medium holding chamber. The cold storage bag can be placed horizontally inside the cold storage medium holding chamber, and can also be placed vertically inside the cold storage medium holding chamber. After the cold storage bag is placed in the cold storage medium holding chamber, at least two side portions of the cold storage bag can fully contact the side portions of two adjacent fins, respectively, and the heat exchange area is large.

[0036] 4. In the cold storage box provided by the present invention, the side walls of the fins are configured to be corrugated, and the corrugated side walls of the fins increase the effective contact area with the cold storage bag, thereby greatly improving the cold transfer effect between the fins and the cold storage bag.

[0037] 5. The cold storage box provided by the present invention has aluminum fins with good thermal conductivity, which reduces thermal resistance.

[0038] 6. The cold storage box provided by the present invention has air doors that can be opened and closed on two opposite side walls of the box body. When cooling is required, the two air doors are opened, and each cold storage medium storage chamber forms an air path connected to the outside world. The blown wind can fully contact the fins, take away the cold on the surface of the fins in the air path, and then the cold of the cold storage medium in the cold storage bag can be discharged by blowing air.

[0041] 9. In the cold storage box provided by the present invention, the cross-sectional area of ​​the fins decreases from bottom to top. Since the cold storage bag is arranged below the cold storage medium storage chamber, and the upper part of the cold storage medium storage chamber is the wind path, the blocking effect on the blowing air is reduced, which facilitates the rapid blowing of the blowing air.

[0057] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0061] Example 1

[0062] like Figures 1 to 5 As shown, this embodiment discloses a cold storage box, including a box body 1, a fin assembly 2 and a cold storage bag 4. The cold storage box in this embodiment is a water-cooled cold storage box, that is, the coldness of the cold storage medium in the cold storage bag 4 in this embodiment is released outward through a heat exchange medium.

[0063] The interior of the box body 1 is in a cavity shape. The box body 1 comprises an outer shell and a heat-insulating layer, and the heat-insulating layer is arranged inside the outer shell.

[0064] The fin assembly 2 is arranged in the cavity of the box body 1, and divides the cavity of the box body 1 into a plurality of cold storage medium storage chambers. The fin assembly 2 performs heat exchange with the refrigeration assembly and the cooling assembly respectively, and then can transfer the cold energy of the refrigeration assembly to the cold storage medium of the cold storage bag, and can transfer the cold energy of the cold storage medium of the cold storage bag through the cooling assembly.

[0065] There are several cold storage bags 4, which are filled with cold storage medium and are respectively placed in each cold storage medium storage cavity. The cold storage medium inside is a substance that can store cold, which can be liquid or solid. The cold storage medium is preferably an aqueous solution, because water has a high heat capacity, is easy to obtain, has low cost, and more importantly, can be made to undergo phase change, and the cold capacity contained in the phase change is extremely high.

[0066] The above-mentioned cold storage box divides the cold storage bags into several parts, each of which is in full contact with the fin assembly 2. The fin assembly 2 arranged inside the box body 1 can increase the effective heat exchange area with the cold storage bag, and the fin assembly 2 can perform more sufficient heat exchange with the cold storage medium in the cold storage bag. Furthermore, when the cold storage box is storing cold, the cold energy input from the outside can be quickly transferred to the cold storage medium in the cold storage bag through the fin assembly 2, which reduces the cold storage time of the cold storage box and improves the efficiency; when the cold storage box is releasing cold, the cold energy can be quickly transferred out through the fin assembly 2.

[0067] As a specific embodiment, the fin assembly 2 includes a connecting plate 22 and fins 21. The connecting plate 22 is in contact with the bottom of the box body 1. More specifically, the connecting plate 22 is configured to be a flat plate. A plurality of fins 21 are provided, which are respectively and spaced apart in sequence on the connecting plate 22. A cold storage medium holding chamber is formed between every two adjacent fins 21. At least one cold storage bag 4 is contained in each cold storage medium holding chamber. The cold storage bag 4 can be placed horizontally inside the cold storage medium holding chamber, or vertically inside the cold storage medium holding chamber. In this embodiment, after the cold storage bag 4 is placed in the cold storage medium holding chamber, at least two side portions of the cold storage bag 4 can be fully in contact with the side portions of two adjacent fins 21, respectively, and the heat exchange area is large.

[0068] like Figure 3 and Figure 4 As shown, two cold storage bags 4 are placed horizontally in each cold storage medium storage chamber. Figure 5 As shown, two cold storage bags 4 are placed vertically in each cold storage medium storage chamber. It should be noted that Figure 3 , Figure 4 , Figure 5 This is only an example. In actual application, the number of cold storage bags in the cold storage medium holding chamber can be arranged according to the actual situation.

[0069] More specifically, Figure 3 As shown, the fin 21 in this embodiment is perpendicular to the connecting plate 22, but the connection between the fin 21 and the connecting plate 22 is not limited to the vertical setting. Figure 2 Only one exemplary arrangement of the fins 21 and the connecting plates 22 is given.

[0070] As a further improved implementation, the larger the contact surface between the fin 21 and the cold storage bag, the better. For this purpose, the side wall of the fin 21 is configured to be corrugated. It should be noted that the corrugation can be wavy, folded, or irregularly curved, and the specific shape is not limited here. The cold storage bag in this embodiment is tightly attached to the corrugated side wall of the fin 21, that is, the cold storage bag is fully squeezed and contacted with the side wall of the fin 21. The corrugated side wall of the fin increases the effective contact area with the cold storage bag, thereby greatly improving the cold transfer effect between the fin 21 and the cold storage bag.

[0071] As a further improved implementation, the fin 21 is an aluminum fin, which has good thermal conductivity and reduces thermal resistance. In addition, the fin 21 can also be made of other materials with good thermal conductivity, and its specific material is not limited here.

[0072] As a further improved embodiment, a cooling member 7 is sealed on the box body 1, one end of the cooling member 7 is in contact with the fin assembly 2, and the other end of the cooling member 7 extends from the box body and exchanges heat with the cooling assembly. More specifically, a through hole is provided at the bottom of the box body 1, and the cooling member 7 passes through the through hole at the bottom of the box body 1, and the cooling member 7 is in contact with the connecting plate 22, so that the cold energy of the cold storage medium in the cold storage bag can be transferred to the connecting plate 22, and then transferred to the cooling member 7, and then the cold energy can be transferred to the cooling assembly through the cooling member 7, and the cold energy is discharged through the cooling assembly.

[0073] As an alternative embodiment, a cooling pipe 8 is provided inside the fin assembly 2, and the end of the cooling pipe 8 extends from the fin assembly 2 and performs heat exchange with the cooling assembly. Fig. 9 That is, the cooling pipe 8 in this embodiment can be connected to the cooling assembly, and then the fin assembly 2 can also discharge the cold through the cooling pipe 8.

[0074] Example 2

[0075] like Figures 1 to 7 As shown, this embodiment discloses a cold storage box. This embodiment adds a damper 3 on the basis of embodiment 1, or removes the cooling member 7 in embodiment 1 and adds an additional damper, so that the cold storage box in this embodiment can cool by blowing air. The cold storage box in this embodiment is an air-cooled cold storage box, and the air path in this embodiment is filled with fins, and the fins in the air path can conduct the cold in the cold storage medium to the outside air.

[0076] like Figure 7As shown, two opposite side walls of the box body 1 are provided with air doors 3 that can be opened and closed. When the two air doors are in the closed state, they have a heat preservation function. When cooling is required, the two air doors 3 are opened, and each cold storage medium storage chamber forms an air path connected to the outside world. The blown wind can fully contact the fins, take away the cold on the surface of the fins in the air path, and then the cold of the cold storage medium in the cold storage bag can be discharged by blowing.

[0077] As a further improved implementation, the arrangement direction of the fins 21 is parallel to the direction of the wind blowing into the wind path, so that the fins are arranged along the wind path, reducing wind resistance and cooling the fins by blowing air.

[0078] As an alternative implementation, Figure 6 As shown, a partition 23 is provided between two adjacent fins 21, and the partition 23 divides the cold storage medium storage chamber into an air path area suitable for ventilation and a cold storage area suitable for storing the cold storage bag. If the blowing air enters the cold storage area, the wind speed will be reduced due to the influence of the cold storage bag. The function of the partition 23 in this embodiment is to distinguish the upper wind path area from the lower cold storage area, so that the blowing air enters the wind path area and contacts the fins 21 in the area, but does not enter the cold storage area, thereby avoiding the problem of reducing the wind speed.

[0079] As a further improved implementation method, Figure 3 As shown, the cross-sectional area of ​​the fin 21 decreases from bottom to top, because the cold storage bag is arranged below the cold storage medium storage chamber, and the upper part of the cold storage medium storage chamber is the wind path, thereby reducing the blocking effect on the blowing air, making it easier for the blowing air to be blown out quickly.

[0080] Example 3

[0081] like Figure 8 and Fig. 9 As shown, this embodiment discloses a cold storage and cooling system, including a refrigeration component 6, a cooling component 5 and the cold storage box in Example 1.

[0082] The cooling assembly 5 performs heat exchange with the fin assembly 2 of the cold storage box and is suitable for releasing the cold in the cold storage box.

[0083] The cooling component 5 in this embodiment is a heat exchange cooling component. The cooling component includes a first heat exchanger 51, a cooling pipeline 52, a first on-off valve 53 and a delivery pump 55. The first heat exchanger 51 has a heat exchange channel and a heat exchange fin, and a heat exchange medium is provided in the heat exchange channel. The cooling pipeline 52 is connected to the heat exchange channel and forms a circulation pipeline, and the cooling pipeline 52 performs heat exchange with the fin assembly 2. The first on-off valve 53 is arranged on the cooling pipeline 52, and is suitable for controlling the on-off of the cooling pipeline 52. The delivery pump 55 is arranged on the cooling pipeline 52, and is suitable for pumping the heat exchange medium in the heat exchange channel to the fin assembly and performing heat exchange with the fin assembly. A first fan 54 is also arranged below the first heat exchanger 51.

[0084] The heat exchange between the cooling pipe 52 and the fin assembly 2 can be carried out through the cooling member 7. The cooling pipe 52 is arranged inside the cooling member 7 extending from the box body. Figure 8 The heat exchange between the cooling pipe 52 and the fin assembly 2 can also be carried out through the cooling pipe 8 led out from the inside of the fin assembly 2, as shown in FIG. Fig. 9 As shown, the cooling pipeline 8 is arranged inside the fin assembly 2, and both ends extend out from the fin assembly 2.

[0085] The refrigeration assembly 6 performs heat exchange with the fin assembly 2 of the cold storage box and is suitable for providing a cold source for the cold storage box. The refrigeration assembly 6 includes a second heat exchanger 61, a cold storage pipeline 62, a compressor 63, a second on-off valve 64 and a second fan 65. The second heat exchanger 61 has a second heat exchange channel and a second heat exchange fin, and the second heat exchange channel has a heat exchange medium. The cold storage pipeline 62 is connected to the second heat exchange channel and forms a second circulation pipeline, and the cold storage pipeline 62 performs heat exchange with the fin assembly 2. The second on-off valve 64 is arranged on the cold storage pipeline 62, and is suitable for controlling the on and off of the cold storage pipeline 62. The compressor 63 is arranged on the cold storage pipeline 62. The second fan 65 is arranged below the second heat exchanger 61.

[0086] Figure 8 The overall structural diagram of the cold storage and cooling system is shown when a layer of cold storage bags is placed in the upper and lower positions of the cold storage medium storage chamber. Fig. 9 The overall structure diagram of the cold storage and cooling system is shown in FIG. 1 when two layers of cold storage bags are placed in the upper and lower positions of the cold storage medium storage chamber. Figure 8 and Fig. 9 This is only an example. In actual application, the number of layers of cold storage bags in the cold storage medium storage chamber can be arranged according to the actual situation.

[0087] When the cold storage and release system is storing cold, the second on-off valve 64 in the refrigeration component is opened, the compressor 63 is running, and the cold energy generated by the refrigeration component is transferred to each fin 21 through the horizontal end surface, and then the cold energy is transferred to the cold storage medium of the cold storage bag through the surface of the fin 21.

[0088] When the cold storage and cooling system is cooling, the cooling assembly is running, the first on-off valve 53 is opened, the delivery pump 55 is running, the cold storage medium in the cold storage bag exchanges heat with the fin assembly 2, then the fin assembly 2 exchanges heat with the heat exchange medium in the cooling pipeline 52, and then the heat exchange medium exchanges heat with the first heat exchanger 51, and then the cold of the cold storage medium in the cold storage bag is released. Cold: cold storage bag → fin → cooling pipeline → first heat exchanger → release.

[0089] Example 4

[0090] like Fig.10 As shown, this embodiment discloses a cold storage and cooling system, including a refrigeration component, a cooling component and the cold storage box in Example 2.

[0091] The refrigeration component exchanges heat with the fin component 2 of the cold storage box and is suitable for providing a cold source for the cold storage box.

[0092] The cooling assembly exchanges heat with the fin assembly 2 of the cold storage box and is suitable for releasing the cold in the cold storage box.

[0093] The difference from the third embodiment is that the cooling component in the present embodiment is a blowing cooling component. The cooling component includes an air duct, in which blowing air is passed, and the cold storage box is arranged in the air duct, and the air duct can be additionally opened on the home appliance.

[0094] When the cold storage and release system is storing cold, the second on-off valve 64 in the refrigeration component is opened, the compressor 63 is running, and the cold energy generated by the refrigeration component is transferred to each fin 21 through the horizontal end surface, and then the cold energy is transferred to the cold storage medium of the cold storage bag through the surface of the fin 21.

[0095] When the cold storage and cooling system is cooling, the two dampers 3 arranged on the box body 1 are opened, and the external air flow passes through the internal air path of the box body. The cooling capacity is: cold storage bag→fins→air flow.

[0096] Example 5

[0097] Air conditioning systems are commonly used household appliances. Air conditioning generally covers indoor living rooms and bedrooms, but cannot cover kitchen and bathroom spaces. However, kitchen and bathroom spaces also have the need to use air conditioning. If air conditioning is introduced into the kitchen and bathroom, holes need to be reserved on the walls of the kitchen and bathroom for the refrigerant pipes of the air conditioner to pass through, and the corresponding indoor units need to be adapted for installation and use. If the air conditioner is connected to the kitchen and bathroom space, it must be reserved in advance by a professional construction team before decoration, preferably during the developer's construction period. However, some customers do not have this demand, and it is difficult to unify the standards. In addition, the cost of adding indoor units is relatively high. If air conditioning equipment is adapted to more indoor units, a larger power and higher performance compressor is required, which will also increase the cost of air conditioning.

[0098] This embodiment discloses a specific application scenario of a cold storage and cooling system, which is installed in a household appliance. Therefore, when installing the cold storage and cooling system in this embodiment, there is no need to reserve holes on the walls of the kitchen and bathroom, which greatly reduces the installation cost. In addition, an independent air duct is opened in the household appliance, which does not affect the operation of the household appliance.

[0099] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
