Description

Technical Field

[0001] The invention relates to the technical field of food preservation, in particular to a food preservation phase change storage device. Background Art

[0002] Food preservation phase change storage device is a technology that uses the property of phase change material (PCM) to absorb or release heat during phase change to achieve food preservation. This device stores and releases energy through the solid-liquid phase change process to achieve the purpose of regulating and maintaining the temperature of the food storage environment.

[0003] The phase change material of the food preservation phase change storage device generally cooperates with the heat exchange mechanism for heat exchange, but in actual use, the position with the highest cold storage efficiency may not be consistent with the position where the food needs to be cooled and preserved, which will lead to a decrease in overall efficiency. For example, if the refrigeration equipment is located on the left and the food to be preserved is located on the right, then although the heat exchange mechanism is installed only on the left side, it can effectively store cold, but the preservation efficiency of the food on the right side during cooling may not be high; conversely, if the heat exchange mechanism is installed on the right side, the cold storage efficiency may be reduced due to the distance from the refrigeration equipment. In addition, if two sets of heat exchange mechanisms are set, although the cold storage efficiency can be guaranteed, the cooling will be carried out through the two sets of heat exchange mechanisms at the same time during cooling, which will cause the cold to be diverted to the non-food side, which may cause energy waste.

[0032] like Figure 2-Figure 3 , Figure 9-10As shown, a guide part 8 is installed on the left side of the partition 13, and the guide part 8 includes four foot blocks 81 fixedly connected to the left end surface of the partition 13. A cover 82 is fixedly connected to the left side of the foot block 81. The inner sides of the cover 82 are fixedly connected with baffles 83. The inner sides of the baffles 83 are provided with through holes 84. The upper shell plate of the cover 82 is provided with a discharge port 85, and the discharge port 85 is located at the right part of the right baffle 83. The upper side of the heat conduction plate 51 is fixedly connected to a heat conduction folding rod 54 located on the left side of the partition 13, and the outer side of the heat conduction folding rod 54 is fixedly connected to The heat conducting sheet 55 between the set of baffles 83 has a plurality of perforations 56 formed on the inner side of the heat conducting sheet 55. This arrangement allows the refrigeration equipment room 16 to be turned on when the electricity price is low. The cold air enters the guide portion 8 through the interface of the warehouse body 11, and is guided by the guide portion 8 to flow through the set of heat conducting sheets 55, slowing down the airflow and making full contact, and then is discharged from the discharge port 85. The cold air then passes over the partition 13 and enters the right part of the warehouse body 11, cooling and preserving the food. In this process, the cold air is decelerated and converged, so that the temperature inside the cover 82 is reduced, so that the temperature that can be conducted by the cold storage and heat conducting portion 5 is reduced.

After the cold air enters the cover shell 82, it is blocked by the left-side baffle plate 83 and can only flow from the left-side through-hole 84 to the upper side of a group of thermal conductive plates 55. Under the obstruction of a group of thermal conductive plates 55, the cold air is forced to slowly pass through the through-hole 56, and then the cold air passes through the right-side baffle plate 83 from the right-side through-hole 84. This setting allows the cold air to fully contact each thermal conductive plate 55 and slows down the airflow speed.

[0033] Workflow: The operations of the food preservation phase change storage device are as follows. Note 1: The electrical appliances of this device are all powered by external power, and the electrical appliances of this device are all controlled and operated by the controller 9; Note 2: The shell 31 of the phase change part 3 stores phase change materials, and the type of the phase change materials is selected according to the temperature required for storing food; High-efficiency cold air conduction operation: When electricity is used at low peak, the electricity price is low, and the refrigeration equipment room 16 can be started to operate at low cost. The cold air generated by the refrigeration equipment room 16 enters the interior of the warehouse body 11 through the interface of the warehouse body 11, and is blocked by the left baffle 83, and can only flow from the left through hole 84 to the upper side of a group of thermal conductive plates 55. Under the obstruction of a group of thermal conductive sheets 55, the cold air is forced to slowly pass through the perforations 56 and fully contact each thermal conductive sheet 55, slowing down the airflow speed. Subsequently, the cold air passes through the right baffle 83 from the right perforation 84 and is discharged through the exhaust port 85. Then, the cold air passes through the partition 13 through the opening 14 and enters the right part of the bin body 11 to cool and preserve the stored food. This process not only effectively cools the food, but also when the cold air slowly passes through the thermal conductive sheet 55, the temperature inside the cover 82 will be further reduced due to the convergence and deceleration of the airflow, so that the temperature that can be conducted by the cold storage thermal conductive part 5 is reduced, thereby enhancing The cold storage efficiency of the subsequent phase change material is improved, so that the food preservation phase change storage device can slowly conduct the cold air, so that the cold air is fully in contact with the temperature conduction mechanism, the cold storage efficiency of the phase change material is enhanced, and the energy loss and low cold storage efficiency caused by the rapid flow of cold air in the traditional refrigeration system are solved; cold storage operation: control the air pump 71 to run, and inflate each ring seat 73 through the shunt pipe 72, and the gas in the ring seat 73 will enter the upper air bag 74, so that the air bag 74 expands and expands to push the upper conduction frame 6 to move upward, and the upward movement of the conduction frame 6 will drive the conduction rod 44 to move upward, so that the conduction rod 44 and the heat exchange folding rod 3 3 falls off and contacts, so that the cooling part 4 and the phase change part 3 are separated from the temperature conduction relationship, so as to avoid the loss of low temperature during the subsequent cold storage. On the other hand, it will drive the temperature conducting slide bar 53 to move up and contact the heat exchange column 34, so that the cold storage temperature conducting part 5 and the phase change part 3 form a temperature conduction relationship. At this time, a group of temperature conducting sheets 55 can fully conduct the low temperature in the cover shell 82 to the temperature conducting slide bar 53 through the temperature conducting folding rod 54, the temperature conducting plate 51, and the temperature conducting seat rod 52, and then conduct the low temperature to the heat exchange frame 32 through the heat exchange column 34, so as to fully cool the photo material in the box shell 31, so that the phase change material solidifies and stores cold. The cold storage operation is completed through the above steps;Cooling operation: The electricity price is higher during peak hours. Stopping or starting the refrigeration equipment room 16 at low power can save electricity. The temperature in the warehouse 11 is detected by the temperature sensor 12. When the temperature reaches the threshold of the phase change material phase change cooling, the air pump 71 is controlled by the controller 9 to evacuate air, so that the air bag 74 shrinks and resets, thereby driving the conduction frame 6 to reset. The reset of the conduction frame 6 drives the temperature conduction slide bar 53 to reset and come into contact with the heat exchange column 34, so that the cold storage temperature conduction part 5 and the phase change part 3 are separated from the temperature conduction relationship, thereby avoiding the loss of low temperature during the subsequent cooling. On the other hand, it will drive the conduction slide bar 53 to reset and come into contact with the heat exchange column 34, thereby causing the cold storage temperature conduction part 5 to break away from the temperature conduction relationship with the phase change part 3, thereby avoiding the loss of low temperature during the subsequent cooling. The guide rod 44 moves downward and contacts the heat exchange folding rod 33, so that the cooling part 4 and the phase change part 3 form a temperature conduction relationship. At the same time, the phase change material changes into a liquid and cools down, so that the low temperature is conducted from the heat exchange folding rod 33 and the conduction rod 44 to the conduction seat 41, and then from the conduction seat 41 to each conduction frame 42, so that each conduction frame 42 set outside the storage bin 22 can cool down and preserve the food stored in the storage bin 22. The cooling operation is completed through the above steps, so that the food preservation phase change storage device can adjust the temperature conduction relationship as needed, thereby improving the efficiency of cold storage and cooling down. ;
