The portable insulation can in the correlation technique mainly relies on box insulation material to keep warm, and along with the rising of external environment temperature, the temperature in the box exceedes the cold-stored temperature range of bacterin very easily to lead to the bacterin to become invalid.
Based on this, the embodiment of the disclosure provides a refrigerating device for a refrigerating box and the refrigerating box, so as to improve the refrigerating effect and the working reliability of the refrigerating box.
The specific application scenario of the refrigerator is not limited, and the refrigerator can be used for various preparations, medicines or organisms requiring refrigeration treatment, such as vaccines, insulin, blood, stem cells, living organs, and the like.
As shown in fig. 1, 2 and 3, some embodiments of the present disclosure provide a cooling device 100 for a refrigerator, which mainly comprises a box body 110, a semiconductor cooling plate 120, a cooling liquid circulation system and a heat dissipation module 170.
The semiconductor chilling plates 120 are disposed on the outside of the case 110 and include a cold end 121 and a hot end 122.
The cooling liquid circulation system includes a liquid pump 130, a liquid cooling head 140, and a cooling liner 150 connected by a pipe 160. The liquid pump 130 is disposed outside the box body 110, and may be disposed on a pipeline between the liquid outlet 152 of the cooling liner 150 and the liquid inlet 141 of the liquid-cooling head 140, or may be disposed on a pipeline between the liquid outlet 142 of the liquid-cooling head 140 and the liquid inlet 151 of the cooling liner 150. The liquid pump 130 is configured to provide a driving force for the flow of the coolant in the coolant circulation system. Liquid cooling head 140 is disposed outside of cassette body 110 and in thermally conductive contact with cold end 121, and is configured to exchange heat with cold end 121. The cooling liner 150 is disposed inside the case 110, has a circumferential shape, and has a first wall cavity configured to receive the cooling liquid 156. The liquid inlet 151 of the cooling liner 150 is communicated with the liquid outlet 142 of the liquid cooling head 140, and the liquid outlet 152 of the cooling liner 150 is communicated with the liquid inlet 141 of the liquid cooling head 140.
The heat dissipation module 170 is disposed outside the case 110 and adjacent to the hot end 122, and configured to dissipate heat of the hot end 122.
The specific type of the cartridge 110 is not limited, and may be a vacuum insulation cartridge or an insulation material cartridge. In some embodiments, the refrigeration unit 100 may be located entirely within the enclosure of the refrigeration case. In other embodiments, at least a portion of the outer surface of the case 110 directly serves as the outer surface of the refrigerator, and the semiconductor cooling plate 120, the liquid cooling head 140, the liquid pump 130, and the heat dissipation module 170 are collectively disposed and disposed in a protective enclosure.
The basic working principle of the semiconductor refrigerating sheet is that when a thermocouple formed by connecting an N-type semiconductor material and a P-type semiconductor material has current flowing through the thermocouple pair, heat transfer can be generated between the two ends, the heat can be transferred from one end to the other end, so that temperature difference is generated to form a cold end and a hot end, and the process is forward heat transfer. Because of the resistance of the semiconductor itself, heat is also generated when current passes through the semiconductor, resulting in reverse heat transfer, and in addition, heat between the cold and hot sides is also transferred through the air and the semiconductor itself in reverse. When the cold end and the hot end reach a certain temperature difference and the positive and reverse heat transfer are mutually offset, the temperature of the cold end and the temperature of the hot end can not be continuously changed. Typically, heat is removed from the hot side to lower the temperature of the hot side, thereby bringing the cold side to a lower temperature.
The liquid cooling head 140 is in heat-conducting contact with the cold end 121 of the semiconductor chilling plate 120, so as to exchange heat with the cold end 121 and cool the internal cooling liquid; the cooled cooling liquid enters the cooling inner container 150, and the refrigerated products surrounded by the cooling inner container 150 are refrigerated to absorb the heat of the internal environment of the refrigerating box; the cooling liquid with the increased temperature flows out of the cooling liner 150 and then enters the liquid cooling head 140 again to perform heat exchange with the cold end 121 of the semiconductor chilling plate 120, which is a circulation process. In the embodiment of the present disclosure, the heat dissipating module 170 dissipates heat to the hot end 122, so that the cold end 121 of the semiconductor refrigeration chip 120 is in a trend of continuous cooling, thereby continuously providing cooling capacity for the liquid cooling head 140.
The cooling liner 150 may be a metal cooling liner, such as an aluminum cooling liner, an aluminum alloy cooling liner, or a copper cooling liner. The inside of the cooling inner container 150 in a surrounding shape defines a refrigerated goods accommodating space 200.
The embodiment of the disclosure cools the internal environment of the refrigerating box through the cooling liquid circulating system, and has the advantages of high cooling efficiency, low energy consumption, low noise, high working reliability, simple and compact structure and low cost compared with the scheme of refrigerating by adopting a compressor in some related technologies. The cooling inner container is integrally in a surrounding plate shape, so that the heat conduction area is larger, the heat conduction efficiency is better, and the internal environment of the refrigerating box can be uniformly cooled, so that the refrigerating efficiency is higher and reliable.
The specific type of the heat dissipation module 170 is not limited. As shown in FIG. 1, in one embodiment, heat dissipation module 170 includes a heat pipe heat sink 171. The main structure of the heat pipe radiator 171 includes a heat conducting block 1711, heat dissipating fins 1712, and a plurality of heat pipes 1713 penetrating the heat dissipating fins 1712 and fixedly connected to the heat conducting block 1711, wherein the heat conducting block 1711 is in heat conducting contact with the hot end 122 of the semiconductor chilling plate 120. In this embodiment, the heat dissipation module 170 further includes a fan 172 disposed opposite to the heat dissipation fins 1712, so that the heat dissipation effect can be accelerated. In some embodiments, the fan 172 may not be provided if the heatpipe heatsink 171 can substantially meet the heat dissipation requirements.
Heat pipes generally comprise a shell, a wick, and end caps, and are generally divided into an evaporator section, an insulator section, and a condenser section. The liquid working medium is heated and evaporated by heat flow in the evaporation section, the steam flows to the condensation section through the heat insulation section, the steam is cooled by cold fluid outside the pipe in the condensation section to release latent heat and is condensed into liquid, and the condensed liquid accumulated in the liquid suction core of the heat dissipation section returns to the evaporation section to absorb heat for evaporation by virtue of the capillary force of the liquid suction core. The heat pipe radiator has the advantages of high radiating efficiency, compact structure, flexible application and high working reliability.
In some embodiments of the present disclosure, the refrigeration device 100 further includes a temperature monitoring module and a control module (not shown in the figures). The temperature monitoring module is configured to monitor at least one temperature parameter of the refrigeration container, such as a temperature at the inlet 151 or the outlet 152 of the cooling liner 150. The control module is configured to control the semiconductor chilling plate 120 and the liquid pump 130 to be turned on in response to the monitored value of the temperature parameter not being lower than the temperature threshold, and to control the semiconductor chilling plate 120 and the liquid pump 130 to be turned off in response to the monitored value of the temperature parameter being lower than the temperature threshold.
The scheme of the embodiment can realize intelligent temperature control of the refrigerating box. When the monitoring value of the temperature parameter is lower than the temperature threshold value, the semiconductor refrigerating sheet 120 and the liquid pump 130 are closed, the cooling liquid in the cooling liquid circulating system does not flow any more at the moment, and the cooling liquid in the cooling inner container 150 does not flow out of the cooling inner container 150 any more, so that heat exchange with the outside is reduced, energy consumption can be saved, and a continuous heat preservation effect within a period of time can be achieved.
In some embodiments of the present disclosure, the control module is further configured to control the liquid pump 130 to shut down in response to the semiconductor chilling plate 120 ceasing to operate. When the semiconductor chilling plate 120 cannot work due to unexpected faults or other reasons, the control module controls the liquid pump 130 to be closed, so that cooling liquid in the cooling inner container 150 cannot flow out of the cooling inner container 150 any more, heat exchange with the outside is reduced, a continuous heat preservation effect can be achieved within a period of time, and the risk of failure of refrigerated products due to unexpected faults can be greatly reduced.
The specific shape of the box 110 is not particularly limited in the present disclosure, for example, the box 110 may be a square box or a barrel-shaped box, and the like, where the square box is, for example, a rectangular box or a square box. In some embodiments, the case 110 is a square case, and the semiconductor chilling plate 120, the liquid pump 130, the liquid cooling head 140 and the heat dissipation module 170 are located outside one of two adjacent sidewalls and are centrally disposed. As shown in fig. 1 and 2, in this embodiment, the case body 110 is a rectangular parallelepiped case body, and the heat dissipation module 170, the semiconductor chilling plate 120, the liquid cooling head 140, the liquid pump 130, and the pipeline 160 are compactly arranged on the outer side of one wide side wall of the case body 110 in the order from bottom to top. The liquid inlet 151 and the liquid outlet 152 of the cooling liner 150 are adjacent to the inner corners of the two adjacent sidewalls of the box body 110, that is, arranged at a corner of the box body 110, and the liquid inlet 151 is located above the liquid outlet 152.
The refrigerating device 100 adopting the above arrangement has a compact structure and occupies a small space, which is beneficial to reducing the volume of the refrigerating box or increasing the refrigerating space under the condition that the volume of the refrigerating box is basically unchanged. On the other hand, the structural arrangement is compact, so that the length of the pipeline can be reduced, the cold loss is reduced, the heat exchange effect of the cold end 121 and the hot end 122 of the semiconductor refrigerating sheet 120 is improved, and the refrigerating effect of the refrigerating box is further improved. In addition, the liquid inlet 151 is disposed above the liquid outlet 152, so that the pressure of the cooling liquid filled into the cooling liner 150 can be reduced, the working resistance of the liquid pump 130 can be reduced, the energy consumption of the liquid pump 130 can be reduced to a certain extent, and the working reliability of the cooling liquid circulation system can be improved.
As shown in fig. 3, in some embodiments of the disclosure, the first wall cavity of the cooling liner 150 is in a non-closed loop shape, and the cooling liner 150 includes a first end plate 153 and a second end plate 154 respectively disposed at two ends of the non-closed loop direction, so that the cooling liner 150 adopting this design is convenient for manufacturing. The inlet port 151 of the cooling liner 150 may be disposed on the first end plate 153 or the second end plate 154, the outlet port 152 may be disposed on the first end plate 153 or the second end plate 154, and the positions of the inlet port 151 and the outlet port 152 may be designed in combination with the specific layout of other components, for example, as shown in the figure, in order to reduce the amount of piping and the loss of cooling capacity, and simplify the piping design, both the inlet port 151 and the outlet port 152 are disposed on the first end plate 153.
As shown in FIG. 4, in other disclosed embodiments, the inner and outer sidewalls of the cooling liner 150 each have a closed perimeter, and the cooling liner 150 includes a longitudinal partition 155 that defines the first wall cavity as a non-closed perimeter. The coolant on both sides of longitudinal partition 155 cannot flow through longitudinal partition 155 to the opposite side.
As shown in fig. 5, in some embodiments, the refrigeration device 100 further includes a cold accumulation liner 180 disposed inside the case 110 and having a surrounding shape, and a second wall cavity configured to accommodate the cold accumulation agent 157. The cold storage inner container 180 is located above or below the cooling inner container 150 and is in heat conductive contact with the cooling inner container 150. The cold accumulation inner container 180 and the cooling inner container 150 can be assembled or welded together, or can be integrally processed and manufactured. The cold accumulation inner container 180 can be made of a metal material with better heat conductivity. In this embodiment, the inner sides of the cooling inner container 150 and the cool storage inner container 180, which are in a surrounding shape, together define a refrigerated goods accommodating space 200 of the refrigerator.
The cold accumulation inner container 180 is integrally in a surrounding plate shape. The second wall cavity is configured to contain a coolant 157, and the coolant may be injected before the refrigerator is shipped, or after the refrigerator is sold, the coolant with a suitable phase transition point may be selected by a user as required. The cold accumulating agent is one kind of translucent, opaque and viscous mixture of organic and/or inorganic compounds, and can absorb and store cold at low temperature and release cold after the temperature reaches its phase change point.
In this embodiment, when the cooling liquid circulation system operates, the low-temperature cooling liquid in the cooling liner 150 transfers the cold energy to the cold storage agent for storage through heat conduction between the liners, that is, the cold storage agent stores the cold as the cooling liquid circulation system operates. Since the temperature of the cooling liquid in the cooling inner container 150 can be controlled by the cooling liquid circulation system, the temperature of the coolant in the cold storage inner container can also be controlled within a certain range, and supercooling can not occur, so that the coolant can be directly released when needed without releasing cold in advance.
When the cooling liquid circulation system stops working and the temperature of the refrigeration environment rises, so that the temperature of the coolant reaches the phase transition point temperature, the coolant releases cold to continuously provide cold for the refrigeration environment, so that the refrigeration environment can still be in a lower and proper temperature range within a longer period of time, for example, the proper refrigeration temperature of vaccines is 2-8 ℃. According to the scheme of the embodiment of the disclosure, the cold storage agent works along with the cooling liquid circulating system to store cold, cold storage and cold release are not required in advance, and a refrigerating device for supplying cold energy to the cold storage inner container is not required to be additionally arranged, so that the refrigeration effect can be improved, the convenience in use is improved, the use preparation time of the refrigerating box is shortened, the design complexity and the cost of the refrigerating box are not increased, and the service life is longer.
