[0032] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the accompanying drawings needed to be used in the description of the embodiments or the prior art will be briefly introduced. Obviously, for those of ordinary skill in the art, other drawings can also be obtained based on these drawings without any creative effort.

[0033] In the following description, a lot of specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0034] As Figures 1 to 5As shown, the embodiment of the present application provides a cold storage tank, which is suitable for a cold storage device, the cold storage device has a refrigeration chamber 11a and a storage chamber 11b, and the cold storage tank is arranged in the refrigeration chamber 11a. Wherein, the cold storage tank comprises a tank body 2, the tank body 2 has a refrigeration air duct 21 and an inner cavity for containing a cold storage agent, the refrigeration air duct 21 has an air inlet 21b and an air outlet 21a, and the air outlet 21a and the air inlet 21b can be communicated with the storage chamber 11b, and the air entering the refrigeration air duct 21 through the air inlet 21b exchanges heat with the cold storage agent in the refrigeration air duct 21.

[0035] Understandably, the cold storage tank can absorb and store the cold energy in the refrigeration chamber 11a by the cold storage agent in the inner cavity, and the tank body 2 of the cold storage tank has the refrigeration air duct 21, so that the air entering the refrigeration air duct 21 through the air inlet 21b exchanges heat with the cold storage agent and is transported to the storage chamber 11b from the air outlet 21a, which not only can realize the refrigeration of the storage chamber 11b, so that the storage chamber 11b can realize the cold storage function and can store goods, but also can continuously release the cold energy by the cold storage agent after power failure or power outage, thereby prolonging the duration of the cold storage function of the storage chamber 11b and improving the user experience.

[0036] In addition, the cold storage tank contains the cold storage agent in the inner cavity, and does not need to exchange heat with the air in the refrigeration air duct 21 by the flowing cold storage agent, so that the structure of the cold storage tank can be simplified.

[0037] It should be noted that the tank body 2 of the above-mentioned cold storage tank can be integrally formed, or can be divided into two parts, for example, the tank body 2 of the cold storage tank is assembled by at least two parts, and the refrigeration air duct 21 is formed between the at least two parts.

[0038] Further, the above-mentioned cold storage tank can further be provided with fins in the refrigeration air duct 21, or the tank body 2 itself can form protrusions in the refrigeration air duct 21, so as to increase the heat exchange area and improve the heat exchange efficiency.

[0039] In some embodiments, referring to Figure 2 and Figure 3 , the refrigeration air duct 21 comprises at least two air duct sections extending along a first direction, and the at least two air duct sections are arranged in sequence in a second direction, and the length of the partition between the adjacent two air duct sections in the first direction is less than the length of any one of the two air duct sections. The air outlet 21a and the air inlet 21b are located on the same side of the tank body 2 in the first direction, and the first direction and the second direction intersect.

[0040] Understandably, the adjacent two air duct sections of the refrigeration air duct 21 are communicated, so as to form a U-shaped air duct, which can increase the heat exchange area and prolong the residence time of the air entering through the air inlet 21b in the refrigeration air duct 21, thereby improving the heat exchange efficiency.

[0041] It should be noted that the refrigeration air duct 21 can be provided with at least one air inlet 21b and at least one air outlet 21a, and one air outlet 21a can correspond to one air inlet 21b, or at least two air inlets 21b can share one air outlet 21a.

[0042] Exemplarily, referring to Figure 3 , the refrigeration air duct 21 includes three air duct segments arranged in the second direction in sequence, one end of the middle air duct segment forms the air outlet 21a, and one end of the other two air duct segments forms the air inlet 21b, at this time the refrigeration air duct has two air inlets 21b and one air outlet 21a, and the air entering from each air inlet 21b flows along the U-shaped air duct and exchanges heat with the cold storage agent in the cold storage tank.

[0043] Among them, the lengths of the three air duct segments in the first direction are the same, and the lengths of the partitions between the adjacent two air duct segments in the first direction are two-thirds to three-quarters of the length of the air duct segment.

[0044] Exemplarily, in a specific implementation, the above-mentioned air duct segments can extend through both sides of the tank 2 in the first direction. That is, both ends of each air duct segment in the first direction are open, and when the cold storage tank is placed in the refrigeration chamber 11a, the same side wall of the refrigeration chamber 11a blocks one of the openings of each air duct segment, so that the adjacent two air duct segments form a U-shaped air duct in cooperation with the partition between the adjacent two air duct segments.

[0045] Alternatively, in another specific implementation, one end of the above-mentioned air duct segment in the first direction has an opening, so that the opening of each air duct segment forms an air inlet or an air outlet, at this time the air inlets and air outlets of the refrigeration air duct are located on the same side of the tank in the first direction.

[0046] In some embodiments, the cold storage tank further comprises a fan assembly 3, which is arranged on the tank 2 and located at the air outlet 21a, and the fan assembly 3 can form circulating air through the refrigeration air duct 21.

[0047] Understandably, by arranging the fan assembly 3, the cold storage tank itself can form circulating air through the refrigeration air duct 21, so that the air in the storage chamber 11b can continuously exchange heat with the cold storage agent, ensuring that the storage chamber 11b is kept at the required temperature, and realizing the refrigeration function.

[0048] The above-mentioned fan assembly 3 can be detachably arranged on the tank 2. In this way, when only the cold storage capacity of the cold storage tank is needed, the fan assembly 3 can be detached from the tank 2 to avoid the influence of low temperature environment on the service life of the fan assembly 3. When the cold storage tank needs to release its stored cold capacity, the fan assembly 3 is installed on the tank 2, so that circulating air through the refrigeration air duct 21 is realized by the fan assembly 3.

[0049] Wherein, the fan assembly 3 can be detachably installed on the box 2 by screw connection, clamping and the like, which is not specifically limited here.

[0050] Further, the cold storage box further comprises a battery (not shown in the figure), which is connected to the fan assembly 3. The battery can supply power to the fan assembly 3, so as to ensure that the fan assembly 3 can keep working in the case of power failure or power outage, thereby realizing sustainable delivery of cold energy into the storage chamber 11b.

[0051] The above-mentioned battery can be integrally arranged with the fan assembly 3, so that the battery is also detachable, facilitating charging of the battery.

[0052] In some embodiments, the above-mentioned cold storage box further comprises an air guide member (not shown in the figure) connected to the box 2, which has an air guide channel, one end of which is communicated with the air outlet 21a, and the other end extends into the storage chamber 11b.

[0053] It can be understood that, by arranging the air guide member, the air guide channel can directly guide the cold air discharged from the air outlet 21a into the storage chamber 11b, which is conducive to the rapid entry of cold energy into the storage chamber 11b, so as to make the temperature of the storage chamber 11b more uniform.

[0054] For example, when the above-mentioned refrigeration chamber 11a of the refrigeration device is located above the storage chamber 11b, the air guide channel extends from top to bottom, so that the cold air discharged from the air outlet 21a can be directly blown to the storage chamber 11b, ensuring the uniformity of the temperature in the storage chamber 11b. Of course, the refrigeration chamber 11a can also be located below the storage chamber 11b, in which case the air guide channel extends from bottom to top. Alternatively, the refrigeration chamber 11a can also be located on one side of the storage chamber 11b in the horizontal direction, in which case the air guide channel extends horizontally to deliver cold air into the storage chamber 11b.

[0055] Of course, the air guide member can also be arranged at the air inlet 21b, in which case one end of the air guide channel is communicated with the air inlet 21b, and the other end extends into the storage chamber 11b.

[0056] As shown in Figure 4 and Figure 5 The present embodiment also provides a refrigeration device, which comprises a cold storage box and a device box 1, the device box 1 having a refrigeration chamber 11a and a storage chamber 11b separated from each other, the cold storage chamber being arranged in the refrigeration chamber 11a, and the air inlet 21b and the air outlet 21a being communicated with the storage chamber 11b.

[0057] Wherein, the device can be a vehicle-mounted refrigerator, a household small refrigerator, and also can be a cold storage box, such as a medical cold storage box, a household medical kit and the like.

[0058] In some embodiments, the cold storage tank further comprises a heat pump system (not shown in the figure) disposed in the device cabinet 1 and capable of refrigerating the refrigeration chamber 11a.

[0059] Understandably, the cold storage tank, by the heat pump system, refrigerates the refrigeration chamber 11a, absorbs cold energy in the refrigeration chamber 11a, and transports the cold energy to the storage chamber 11b through the circulating air of the refrigeration air duct 21 formed by the fan assembly 3 to achieve the refrigeration function of the storage chamber 11b, and the cold storage tank can store cold energy, so that when the power is off or disconnected, the fan assembly 3 is powered by the battery to transport the stored cold energy in the cold storage tank to the storage chamber 11b through the circulating air of the refrigeration air duct 21, thereby prolonging the duration of the refrigeration function of the storage chamber 11b and improving the user experience.

[0060] That is, compared with the existing refrigerator or device with freezing and refrigeration functions, the cold storage tank cancels the original evaporator of the refrigeration chamber and uses the refrigeration chamber 11a to provide cold energy to the storage chamber 11b, and stores cold energy by the cold storage tank to continuously transport cold energy to the storage chamber 11b for a certain period of time when the power is off. Of course, the refrigerator or device with freezing and refrigeration functions can also be modified to remove the evaporator of the refrigeration chamber and set the cold storage tank in the freezing chamber.

[0061] It should be noted that the refrigeration device has a power interface or power cord for connecting an external power source, such as when the power is not off, the heat pump system is powered by the external power source, at which time the battery can also be charged, and when the power is off, the fan assembly 3 is powered by the battery, and the heat pump system does not work, and the cold storage function of the storage chamber 11b is ensured by the cold energy stored by the cold storage tank. Of course, the refrigeration device can also be powered by the external power source to work Nh, and then actively disconnected to work Mh, N>0, M>0, and the circulating air of the refrigeration air duct 21 formed by the fan assembly 3 after the power is off transports cold energy to the storage chamber 11b.

[0062] The above power interface can be a direct current input power interface, and the entire device can be powered by an adapter. The adapter can be a mains-to-direct-current adapter, a diesel-to-direct-current adapter, etc.

[0063] In some embodiments, the device cabinet 1 comprises a cabinet body 11 and a first door body 12, the cabinet body 11 has a refrigeration chamber 11a and a storage chamber 11b, and the first door body 12 is rotatably connected to the cabinet body 11 and can close or open the refrigeration chamber 11a. The first door body 12 is provided with a transition passage 12a corresponding to the air inlet 21b and the air outlet 21a.

[0064] Understandably, the circulating air formed by the fan assembly 3 can pass through the transition passage 12a and the air inlet 21b of the refrigeration air duct 21 into the refrigeration air duct 21, and then pass through the air outlet 21a of the refrigeration air duct 21 and the transition passage into the storage cavity 11b. The first door body 12 can separate the refrigeration cavity 11a and the storage cavity 11b, so as to avoid the cold air in the refrigeration cavity 11a directly entering the storage cavity 11b, thereby allowing the temperature in the storage cavity 11b to be controlled by controlling the air volume of the circulating air by the fan assembly 3.

[0065] In addition, in this case, the fan assembly 3 and the battery of the cold storage tank can also be installed on the first door body 12.

[0066] It should be noted that, at this time, the cold storage tank is directly arranged in the refrigeration cavity 11a, and when the first door body 12 closes the refrigeration cavity 11a, the refrigeration cavity 11a can only communicate with the storage cavity 11b through the refrigeration air duct 21 of the cold storage tank and the transition passage 12a on the first door body 12. At this time, the first door body 12 is provided with a sealing element around.

[0067] The cold storage tank can be arranged to be the same size as the refrigeration cavity 11a, so that the cold storage tank just fills the refrigeration cavity 11a. At this time, the refrigeration cavity 11a only provides cold air, and does not serve as a storage space. Of course, the cold storage tank can also be arranged to be smaller than the refrigeration cavity 11a, so that the remaining space of the refrigeration cavity 11a can also serve as a storage space.

[0068] Further, the equipment cabinet 1 further comprises a second door body (not shown in the figure) rotatably connected to the cabinet body 11, and the cabinet body 11 has an opening, and the second door body can open or close the opening of the cabinet body 11. Understandably, at this time, the cabinet body 11 has a refrigeration cavity 11a and a storage cavity 11b, wherein the first door body 12 can close the refrigeration cavity 11a, and the second door body can simultaneously close the storage cavity 11b and the refrigeration cavity 11a. When the cold storage tank occupies the entire space of the refrigeration cavity 11a, the refrigeration cavity 11a does not serve as a storage space, the first door body 12 remains in a closed state, and the second door body is mainly used to open and close the storage cavity 11b.

[0069] Alternatively, in other embodiments, a partition plate separating the refrigeration cavity and the storage cavity can also be arranged in the equipment cabinet, and a transition passage is formed on the partition plate corresponding to the air outlet and the air inlet. The transition passage can also achieve the communication between the refrigeration air duct and the storage cavity, and the air outlet directly blows the cold air passing through the refrigeration air duct into the storage cavity. In this case, the fan assembly and the battery of the cold storage tank can be installed on the partition plate and located in the storage cavity.

[0070] It has to be noted that, in the present document, relational terms are intended only to convey a possible relationship between elements or
