Description

Technical Field

[0001] The present invention relates to the technical field of low-power refrigeration equipment, and in particular to a refrigeration and cold storage device and a temperature control system having the same. Background Art

[0002] When the semiconductor thermoelectric element is powered on, electron-hole pairs are generated near the upper contact, the internal energy decreases, the temperature drops, and heat is absorbed from the outside, which is called the cold end. The other end increases the internal energy and temperature due to the recombination of the electron-hole pairs, and releases heat to the environment, which is called the hot end. The temperature difference and cooling capacity generated by a pair of semiconductor thermoelectric elements are very small, so the semiconductor refrigeration technology in the prior art is mainly used in occasions with small cooling capacity and small space, such as cooling of certain components in electronic equipment and radio communication equipment.

[0003] In the prior art, in order to apply semiconductor refrigeration technology to household products to cool the room, it is necessary to connect many pairs of semiconductor thermoelectric elements in parallel or in series to form a semiconductor refrigerator, also known as a semiconductor thermopile, to increase the temperature difference between the cold end and the hot end. However, due to the small cooling coefficient of semiconductors and relatively large power consumption, when the number of semiconductor thermoelectric elements increases, the energy consumption of the refrigerator will increase rapidly, resulting in extremely high energy consumption and operating costs of household products related to semiconductor refrigeration technology.

[0004] In order to reduce the operating costs of home semiconductor refrigeration equipment, we use semiconductor continuous cold storage during the research and development process. When the user needs refrigeration, we use the cold energy accumulated in the cold storage equipment to perform refrigeration. However, during the research and development process, we found that when using semiconductors for cold storage, the water cooling capacity in the cold storage box is uneven, and it is easy to freeze and seal in the area close to the semiconductor chip, reaching a false saturation state, causing the water in the cold storage box to no longer absorb the cold energy of the semiconductor chip before it is completely frozen, resulting in the cold storage capacity of the semiconductor cold storage equipment being far lower than the design value and a large amount of cold energy wasted. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that when semiconductors are used for cold storage, the area close to the semiconductor chip in the cold storage box will be frozen and sealed, reaching a pseudo-saturation state, thereby providing a refrigeration cold storage device and a temperature control system having the same.

[0006] In order to solve the above technical problems, the present invention provides a refrigeration and cold storage device, comprising:

[0007] A containing assembly, used for containing a cold storage component;

[0008] A refrigeration component, a temperature transmission member is provided at a cold end thereof, and the temperature transmission member extends toward the inner cavity of the accommodation component;

[0009] The disturbance component is installed in the inner cavity of the containing component and is used to disturb the cold storage component to make the cold storage component move in the inner cavity of the containing component.

[0010] Optionally, the disturbance component includes a driving member and a disturbance member, the driving member is fixedly connected to the containing component, and the disturbance member is installed at the driving end of the driving member.

[0014] The present invention also provides a temperature control system having the refrigeration and cold storage device described in the present invention.

[0015] Optionally, it also includes:

[0016] A heat exchange device, on which a heat exchange pipeline is arranged;

[0017] The first circulation pipeline has two ends respectively connected with the inlet and outlet of the heat exchange pipeline, and the first circulation pipeline extends into the inner cavity of the containing component.

[0018] Optionally, a second circulation pipeline is provided at the hot end of the refrigeration component, and two ends of the second circulation pipeline are respectively connected to an inlet of the heat exchange pipeline and an outlet of the heat exchange pipeline.

[0019] Optionally, a reversing valve is installed on the inlet and the outlet of the heat exchange pipeline, and the first circulation pipeline and the second circulation pipeline are connected to the heat exchange pipeline through the reversing valve.

[0020] Optionally, heat-dissipating fins are installed on the heat-exchange pipeline, and the heat-dissipating fins are arranged vertically to the heat-exchange pipeline.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The refrigeration and cold storage device provided by the present invention includes: a containing assembly for containing a cold storage component; a refrigeration assembly, a cold end of which is provided with a temperature transmission component, and the temperature transmission component extends toward the inner cavity of the containing assembly; a disturbance assembly, installed in the inner cavity of the containing assembly, and used to disturb the cold storage component to make the cold storage component move in the inner cavity of the containing assembly.

[0023] When the refrigeration and cold storage device is working, the cold storage part is filled in the containing component. The refrigeration component works to cool, and the cold end of the refrigeration component transfers the cold to the containing component through the temperature transmission part, and stores the cold in the cold storage part of the containing component. During the cold storage process, the disturbance component starts to work, causing the cold storage part to move in the containing component. The cold storage part is made to continuously move around the temperature transmission part, and then continuously take the cold on the temperature transmission part to the cold storage part far away from the temperature transmission part, so that the temperature of the cold storage part in the containing component can be evenly distributed, so that the cold storage parts at various locations can be cooled down and the phase change process can be carried out synchronously, avoiding the accumulation of cold around the temperature transmission part. The cold storage parts far away from the temperature transmission part can also be cooled down and undergo a phase change, which can effectively avoid the generation of a false saturation state caused by the temperature transmission part being surrounded by a fixed cold storage part, thereby improving the cold storage capacity and cold storage capacity of the refrigeration and cold storage device.

[0024] 2. In the refrigeration cold storage device provided by the present invention, the disturbance component includes a driving member and a disturbance member, the driving member is fixedly connected to the containing member, and the disturbance member is installed at the driving end of the driving member.

[0025] 3. The temperature control system provided by the present invention also includes: a heat exchange device, on which a heat exchange pipeline is arranged; a first circulation pipeline, whose two ends are respectively connected to the inlet and outlet of the heat exchange pipeline, and the first circulation pipeline extends into the inner cavity of the accommodation component. The refrigerant moves in the first circulation pipeline and the heat exchange pipeline. When the refrigerant flows to the accommodation component, it absorbs the cold energy of the cold storage component to cool down and brings the cold energy out of the accommodation component. When the refrigerant continues to flow to the heat exchange pipeline, it exchanges heat with the outside through the heat exchange device to provide cold energy for the user end.

[0026] 4. The temperature control system provided by the present invention is provided with a second circulation pipeline at the hot end of the refrigeration component, and the two ends of the second circulation pipeline are respectively connected to the inlet and outlet of the heat exchange pipeline. By connecting the second circulation pipeline at the hot end of the refrigeration component with the heat exchange pipeline, when the refrigeration component is working to store cold in the containing component, the refrigerant flows between the second circulation pipeline and the heat exchange pipeline. When the refrigerant flows through the hot end of the refrigeration component in the second circulation pipeline, it absorbs the heat of the refrigeration component. When the refrigerant continues to move to the heat exchange pipeline, it can dissipate heat to the outside through the heat exchange device. Thereby, the hot end of the refrigeration component is cooled.

[0027] 5. In the temperature control system provided by the present invention, a reversing valve is installed on the inlet and outlet of the heat exchange pipeline, and the first circulation pipeline and the second circulation pipeline are connected to the heat exchange pipeline through the reversing valve.

[0036] 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.

[0037] Example 1

[0038] This embodiment provides a refrigeration and cold storage device, including a containing assembly 1, a refrigeration assembly 4 and a disturbance assembly installed inside the containing assembly 1.

[0039] like Figure 1 As shown, the container assembly 1 is used to contain the cold storage component. In this embodiment, the container assembly 1 is a sealed box with a foam insulation layer, and the cold storage component is water or a mixed solvent of water and a cold storage agent such as blue ice.

[0040] The disturbance component is installed in the inner cavity of the containing component 1, and is used to disturb the cold storage component to make the cold storage component move in the inner cavity of the containing component 1. The disturbance component includes a driving component 2 and a disturbance component 3. The driving component 2 is fixedly connected to the containing component 1, and the disturbance component 3 is installed at the driving end of the driving component 2. In this embodiment, the driving component 2 is a driving motor, and the disturbance component 3 is a rotating fan blade installed on the output shaft of the driving motor. In some embodiments, the disturbance component 3 can also be a spiral blade installed on the output shaft of the driving motor. In order to reduce the space occupied by the disturbance component 3 in the inner cavity of the containing component 1, in other embodiments, the disturbance component 3 can also be an ultrasonic generator, which is fixedly installed on the inner wall of the containing component 1, and the driving component 2 is a power supply component such as a battery or AC power. In other embodiments, such as Figure 3As shown, the driving member 2 can also be a water pump, and the disturbing member 3 can be a liquid pumping pipe. The liquid pumping pipe can be installed at both the liquid inlet and liquid outlet of the water pump, or only at the liquid inlet of the water pump.

[0041] The cold end of the refrigeration component 4 is provided with a temperature transmission member, which extends toward the inner cavity of the accommodation component 1. The temperature transmission member includes a fixed mounting plate 5 as a mounting portion and a cooling fin 6 as a cooling portion. The cold end of the refrigeration component 4 is fixedly mounted on the fixed mounting plate 5, and the cooling fin 6 is fixedly connected to the fixed mounting plate 5. The fixed mounting plate 5 is provided with a plurality of cooling fins 6 at intervals, and the plurality of cooling fins 6 extend into the inner cavity of the accommodation component 1. When the refrigeration cold storage device is working, the cooling fin 6 is immersed in water as a cold storage member.

[0042] In this embodiment, the refrigeration component 4 uses a single-layer semiconductor chip. In other embodiments, the refrigeration component 4 can also be a multi-layer semiconductor chip or a single-layer semiconductor chip and a multi-layer semiconductor chip in series or in parallel. When the refrigeration component 4 uses a semiconductor chip, the cold end of the semiconductor chip is fixedly attached to the fixed mounting plate 5, and the fixed mounting plate 5 is fixedly connected to the inner wall of the cold storage component. In other embodiments, the refrigeration component 4 can also be a compressor refrigeration mechanism, which includes a compressor body, a refrigeration pipeline installed at the refrigeration end of the compressor body, and a heat dissipation pipeline installed at the heat dissipation end of the compressor body. Heat exchangers flow in both the refrigeration pipeline and the heat dissipation pipeline. The refrigeration pipeline extends into the containing component 1. The portion of the refrigeration pipeline extending into the containing component 1 acts as a temperature transmission component to exchange heat with water as a cold storage component, and stores the cold energy generated during the operation of the compressor body in the cold storage component.

[0043] When the refrigeration and cold storage device is working, the cold storage part is filled in the containing component 1. The refrigeration component 4 works to refrigerate, and the cold end of the refrigeration component 4 transfers the cold to the containing component 1 through the temperature transmission component, and stores the cold in the cold storage part of the containing component 1. During the cold storage process, the disturbance component starts to work, causing the cold storage part to move in the containing component 1. The cold storage part is made to continuously move around the temperature transmission part, and then continuously take the cold on the temperature transmission part to the cold storage part far away from the temperature transmission part, so that the temperature of the cold storage part in the containing component 1 can be evenly distributed, so that the cold storage parts in various places can be cooled down and the phase change process can be carried out synchronously, avoiding the accumulation of cold around the temperature transmission part. The cold storage parts far away from the temperature transmission part can also be cooled down and undergo a phase change, which can effectively avoid the generation of a false saturation state caused by the temperature transmission part being surrounded by a fixed cold storage part, thereby improving the cold storage capacity and cold storage capacity of the refrigeration and cold storage device.

[0044] Example 2

[0045] Figure 1 and Figure 2The present embodiment provides a temperature control system, which has the refrigeration and cold storage device described in Embodiment 1 and a heat exchange device for exchanging heat with the user end. The temperature control system in this embodiment takes a kitchen air conditioner or a bathroom air conditioner as an example, and is used to cool small spaces such as kitchens and bathrooms in a home and rooms with short usage time.

[0046] The heat exchange device is provided with a heat exchange pipeline 9. The heat exchange pipeline 9 is provided with heat radiating fins 11. In order to increase the heat exchange area, the heat radiating fins 11 are arranged vertically with the heat exchange pipeline 9. The heat exchange pipeline 9 is provided with a driving pump 13 for driving the flow of the heat exchange agent. In order to increase the temperature exchange capacity of the heat exchange device, a heat dissipation fan 10 can also be installed on the heat exchange device to blow air to the heat radiating fins 11 to increase the heat dissipation or cooling capacity of the heat exchange device. In other embodiments, the heat exchange device can also be a heat exchange device such as a heat pipe heat exchanger, a microchannel heat exchanger, a plate heat exchanger, a sheet mesh snail wire tube heat exchanger, etc.

[0047] A first circulation pipeline 7 is installed between the heat exchange device and the accommodation component 1, and the two ends of the first circulation pipeline 7 are respectively connected to the inlet and outlet of the heat exchange pipeline 9, and the first circulation pipeline 7 extends into the inner cavity of the accommodation component 1. In order to dissipate heat from the hot end of the refrigeration component 4, a second circulation pipeline 8 is provided at the hot end of the refrigeration component 4, and the two ends of the second circulation pipeline 8 are respectively connected to the inlet and outlet of the heat exchange pipeline 9.

[0048] In order to reduce the equipment cost and the space occupied by the whole equipment, a reversing valve 12 is installed at the inlet and outlet of the heat exchange pipeline 9, and the first circulation pipeline 7 and the second circulation pipeline 8 are connected to the heat exchange pipeline 9 through the reversing valve 12. The user-side cold and cold storage components share the same heat exchange equipment, and the user-side cold state and the cold storage component working state in the temperature control system operate alternately. Specifically, during the idle time when no one is using the kitchen or bathroom, taking a single-layer semiconductor chip as a cold storage component as an example, Figure 1 As shown, the single-layer semiconductor chip works as a cold storage component. The cold end of the cold storage component is refrigerated, and the cold is stored in the cold storage component in the containing component 1 through the temperature transmission component. The hot end of the cold storage component needs to dissipate heat. By installing a water cooling head at the hot end of the cold storage component, the second circulation pipeline 8 is set in the water cooling head. At this time, the second circulation pipeline 8 is connected with the heat exchange pipeline 9. The heat exchange agent in the second circulation pipeline 8 absorbs the heat of the hot end of the cold storage component through the driving pump 13, and dissipates the heat to the outside air through heat exchange with the air in the heat exchange device. Figure 2As shown, during the use of the bathroom or kitchen, the cold storage component stops working, the reversing valve 12 switches the heat exchange pipeline 9 to connect with the first circulation pipeline 7, and the driving pump 13 drives the heat exchanger in the first circulation pipeline 7 to move in the first circulation pipeline 7 and the heat exchange pipeline 9. When the heat exchanger passes through the inner cavity of the containing component 1, it exchanges heat with the colder cold storage component to cool down, absorbs the cold stored in the cold storage component, and when the heat exchanger flows through the heat exchange channel, it exchanges heat with the outside air through the heat dissipation fins 11, and dissipates the cold to the outside air to cool the outside.

[0049] By installing the refrigeration cold storage device provided in Example 1, during the cold storage process, the cold storage component continuously moves around the temperature transmission component, and then continuously takes the cold on the temperature transmission component to the cold storage component far away from the temperature transmission component, so that the temperature of the cold storage component in the receiving component 1 can be evenly distributed, so that the cold storage components in various places can be cooled and cooled to phase change simultaneously, avoiding the accumulation of cold around the temperature transmission component. The cold storage components far away from the temperature transmission component can also be cooled and phase changed, which can effectively avoid the generation of a false saturation state caused by the temperature transmission component being surrounded by a fixed cold storage component, and improve the cold storage capacity and cold storage capacity of the refrigeration cold storage device. During the cold use process at the user end, the cold storage component in the receiving component 1 can provide more cold, so that the temperature control system can cool a larger space and an environment with a larger temperature difference, which can increase the application scenarios and temperature control capabilities of the temperature control system.

[0050] As an alternative embodiment, the first circulation pipeline 7 and the second circulation pipeline 8 are respectively connected to different heat exchange devices.

[0051] Obviously, the above embodiments are merely examples for the purpose of 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 therefrom are still within the scope of protection of the invention.
