Description

Technical Field

[0001] The invention relates to the technical field of food thawing, in particular to a thawing plate. Background Art

[0002] In real life, some edible foods such as meat, fish and shellfish usually need to be frozen for storage. However, as people's pace of life accelerates, how to quickly thaw food has become a problem faced by modern people.

[0003] The two most common ways to thaw frozen food are to thaw at room temperature or to thaw in water. The main principle is that food absorbs heat by contact with air and water, thereby thawing the food. However, this thawing method requires a long thawing time and cannot meet the needs of users.

[0004] At present, the thawing plate is a product with good thawing effect for frozen food. Usually, the thawing plate is filled with refrigerant, and the refrigerant liquefies and releases heat to thaw the food through heat exchange.

[0005] Those skilled in the art can further optimize the design of the thawing plate to improve the thawing effect. Summary of the invention

[0006] The object of the present invention is to provide a thawing plate to further improve the thawing effect of the thawing plate.

[0007] To achieve the above object, the following technical solution is adopted: a thawing plate, the thawing plate includes a heat exchange component, the heat exchange component has a heat exchange function, the heat exchange component is provided with a first upper plate portion, a first lower plate portion arranged opposite to the first upper plate portion, and a first connecting portion connecting the first upper plate portion and the first lower plate portion, the first upper plate portion, the first lower plate portion and the first connecting portion form at least one first flow channel, and a heat exchange medium is provided in at least one first flow channel;

[0008] It also includes a heat storage component, which has a heat storage function, and the heat exchange component is integrally formed with or fixedly connected to the heat storage component.

[0009] The thawing plate provided by the present invention, when low-temperature food to be thawed is placed on the first upper plate portion of the heat exchange component, the lower temperature of the food causes the temperature of the place where the first upper plate portion contacts the food to be lowered through heat conduction. Since the heat exchange medium (such as refrigerant) in the first flow channel is in a gas-liquid mixed state, and since the density of the gaseous refrigerant and the liquid refrigerant is different, the gaseous refrigerant is roughly located above the first flow channel, and the liquid refrigerant is roughly located below the first flow channel. At this time, the gaseous refrigerant located above the first flow channel will liquefy into liquid refrigerant when subjected to low temperature. During the liquefaction process, a certain amount of heat will be released at the same time. This heat will inhibit or slow down the decrease in temperature of the contact portion between the first upper plate portion and the food, thereby making the heat exchange between the food and the heat exchange component more continuous and efficient.

[0010] However, the gaseous refrigerant in the first flow channel is not infinite. As more and more gaseous refrigerant is liquefied into liquid refrigerant, the content of gaseous refrigerant in the first flow channel will gradually decrease, and the thawing effect on food will gradually decrease as the thawing time increases.

[0011] The thawing plate provided by the present invention also includes a heat storage component, which is fixedly connected to the heat exchange component or integrally formed. The heat storage medium in the heat storage component can provide heat for the refrigerant in the heat exchange component, and can relatively increase the evaporation rate of the refrigerant to replenish the gaseous refrigerant in the first flow channel to improve the thawing effect.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 7 ,in, Figure 1 A schematic structural diagram of an unsealed thawing plate in a first embodiment of the present invention is provided; Figure 2 for Figure 1 Schematic diagram of the structure of the heat exchange component Figure 3 for Figure 2 A cross-sectional schematic diagram of a heat exchange component; Figure 4 for Figure 2 A partial schematic diagram of a heat exchange component; Figure 5 for Figure 1 A schematic diagram of the structure of the heat storage component; Figure 6 This is a schematic diagram of the working principle of the thawing plate; Figure 7 It is a schematic diagram of the structure of a sealed thawing plate;

[0026] Please refer to Figures 1 to 3In a specific embodiment, the thawing plate provided by the present invention mainly includes a heat exchange component 1 and a first heat storage component 2A, wherein the heat exchange component 1 mainly includes a first upper plate portion 11 and a first lower plate portion 12, the first upper plate portion 11 is roughly a plate-shaped structure, which is roughly located above the heat exchange component 1, and the first lower plate portion 12 is also roughly a plate-shaped structure, which is roughly located below the heat exchange component 1. At the same time, at least two first connecting portions 13 are provided between the first upper plate portion 11 and the first lower plate portion 12, and the first connecting portion 13 simultaneously connects the first upper plate portion 11 and the first lower plate portion 12 of the heat exchange component 1. At this time, a first flow channel 14 is formed between the first upper plate portion 11, the first lower plate portion 12 and the at least two first connecting portions 13. The heat exchange component 1 can be formed by extrusion or machining of aluminum material. Of course, the heat exchange component 1 can also be made of metals with high thermal conductivity such as copper or stainless steel.

[0027] In this embodiment, the number of the first flow channels 14 is multiple. Specifically, when the number of the first flow channels 14 is set to multiple, at least multiple first connecting portions 13 are provided between the first upper plate portion 11 and the first lower plate portion 12 of the heat exchange component 1. The multiple first connecting portions 13 are sequentially arranged at intervals. At this time, the number of the first flow channels 14 defined by the first upper plate portion 11 and the first lower plate portion 12 of the heat exchange component 1 and the multiple first connecting portions 13 is also more than one. Of course, it is also feasible to provide only one or two first flow channels 14.

[0028] In addition, a heat exchange medium (not marked in the drawings) is also provided in the first flow channel 14. The heat exchange medium may be a refrigerant. Therefore, the heat exchange component 1 has a heat exchange function. Each first flow channel 14 may be in a connected state or in a disconnected state. In addition, it is not limited to the flow channel with a heat exchange medium as the first flow channel 14, but the number of first flow channels 14 with a heat exchange medium is more than one (including one).

[0029] Please refer to Figure 6 The working principle of the heat exchange component 1 is as follows: when the first upper plate portion 11 of the heat exchange component 1 is placed with low-temperature food that needs to be thawed, the lower temperature of the food causes the temperature of the position where the first upper plate portion 11 contacts the food to decrease through heat conduction. Since the refrigerant in the first flow channel 14 is in a gas-liquid mixed state, and since the density of the gaseous refrigerant and the liquid refrigerant is different, the gaseous refrigerant is roughly located above the first flow channel 14, and the liquid refrigerant is roughly located below the first flow channel 14. At this time, the gaseous refrigerant located above the first flow channel 14 will liquefy into liquid refrigerant when subjected to low temperature, and a certain amount of heat will be released during the liquefaction process.

[0030] Due to the temperature difference between the low-temperature food and the first upper plate portion 11, the heat exchange between the food and the heat exchange component 1 will continue. The heat released by the liquefaction of the gaseous refrigerant will inhibit or slow down the decrease in temperature of the contact part between the first upper plate portion 11 and the food, thereby making the heat exchange between the food and the heat exchange component 1 more continuous and efficient.

[0031] In addition, since the gaseous refrigerant at the contact point between the first upper plate portion 11 and the food is liquefied into liquid refrigerant due to the low temperature, the air pressure in the first flow channel 14 opposite to the contact point between the first upper plate portion 11 and the food will be reduced accordingly.

[0032] Since the air pressure in the first flow channel 14 relative to the contact point between the first upper plate portion 11 and the food will be reduced accordingly, part of the remaining gaseous refrigerant in the first flow channel 14 will flow to the place where the air pressure is reduced to achieve a dynamic balance of the air pressure in the first flow channel 14. When the gaseous refrigerant in the first flow channel 14 flows to the place with lower air pressure, more gaseous refrigerant is affected by the low temperature and liquefied to release heat, thereby suppressing or slowing down the temperature drop at the contact point between the first upper plate portion 11 and the food, so that the food thawing can continue.

[0033] However, the gaseous refrigerant in the first flow channel 14 is not infinite. As more and more gaseous refrigerant is liquefied into liquid refrigerant, the content of gaseous refrigerant in the first flow channel 14 will gradually decrease, and the thawing effect on food will gradually decrease as the thawing time increases.

[0034] Therefore, an attempt can be made to increase the evaporation rate of the liquid refrigerant to replenish the gaseous refrigerant in the first flow channel 14 and reduce the reduction rate of the gaseous refrigerant in the first flow channel 14 .

[0035] Please refer to Figure 5 To achieve the above purpose, the present embodiment further provides a first heat storage component 2A, which mainly includes a second upper plate portion 21 and a second lower plate portion 22. The second upper plate portion 21 is roughly in a plate-like structure and is roughly located above the first heat storage component 2A. The second lower plate portion 22 is also roughly in a plate-like structure and is roughly located below the first heat storage component 2A. At the same time, at least two second connecting portions 23 are provided between the second upper plate portion 21 and the second lower plate portion 22. The second connecting portions 23 simultaneously connect the second lower plate portion 22 and the second upper plate portion 21 of the first heat storage component 2A. At this time, a second flow channel 24 is formed between the second upper plate portion 21, the second lower plate portion 22 and the second connecting portions 23. A heat storage agent or a heat storage medium with a higher specific heat capacity (not marked in the drawings) is also provided in the second flow channel 24. In this patent, the heat storage medium is defined as a substance with a larger specific heat capacity than the refrigerant under standard conditions, and common ones include water, alcohol, kerosene, etc. The first heat storage component 2A can be formed by extrusion or lathing of aluminum material. Of course, the first heat storage component 2A can also be made of metal with high thermal conductivity such as copper or stainless steel.

[0036] Please refer to Figure 8 The heat exchange component 1 and the first heat storage component 2A can be integrally formed. Specifically, the first heat storage component 2A is located below the heat exchange component 1, and the first lower plate portion 12 and the second upper plate portion 21 are integrally formed, that is, the first lower plate portion 12 of the heat exchange component 1 is also the second upper plate portion 21 of the first heat storage component 2A.

[0037] Of course, please refer to Figure 7 , the heat exchange component 1 and the first heat storage component 2A can also be fixedly connected. Specifically, the first heat storage component 2A is located below the heat exchange component 1, and the first lower plate portion 12 and the second upper plate portion 21 are fixedly connected by welding or gluing. At this time, the first lower plate portion 12 of the heat exchange component 1 is not the second upper plate portion 21 of the first heat storage component 2A. When the first lower plate portion 12 and the second upper plate portion 21 are fixedly connected by gluing, it is appropriate to use glue with high heat conduction efficiency.

[0038] Since the specific heat capacity of the liquid in the second flow channel 24 is higher than that of the refrigerant, it needs to absorb more heat when raising the temperature by the same amount, and release more heat when lowering the temperature by the same amount. At this time, when food with a lower temperature is placed on the thawing plate, the temperature of the heat exchange medium in the first flow channel 14 is lower than the temperature of the heat storage medium in the second flow channel 24. At this time, the heat storage agent in the first heat storage component 2A can provide heat for the heat exchange medium (such as liquid refrigerant) in the heat exchange component 1, which can relatively increase the evaporation rate of the liquid refrigerant and provide more gaseous refrigerant.

[0039] Since the temperature around the liquid is one of the factors affecting the speed of liquid evaporation, this embodiment provides heat for the evaporation of the liquid refrigerant in the first flow channel 14 by setting a heat storage agent or a heat storage medium with a higher specific heat capacity in the first heat storage component 2A, thereby relatively increasing the evaporation rate of the liquid refrigerant.

[0040] In addition, since the refrigerant in the first flow channel 14 undergoes gas-liquid conversion, the gas-liquid conversion will be accompanied by changes in the air pressure in the heat exchange component 1. At this time, the provision of multiple first connecting parts 13 can also enhance the strength of the heat exchange component 1 and increase the service life of the thawing plate.

[0041] Of course, multiple second connecting parts 23 can also be set between the second upper plate part 21 and the second lower plate part 22 of the first heat storage part 2A to increase the strength of the heat storage part. For example, in this embodiment, multiple second connecting parts 23 are set between the second upper plate part 21 and the second lower plate part 22.

[0042] In addition, please refer to Figure 8The first flow channel 14 and the second flow channel 24 also need to be sealed to isolate the heat exchange medium in the first flow channel 14 and the heat storage medium in the second flow channel 24 from the outside. Specifically, the thawing plates at both ends in the direction of the first flow channel 14 and the direction of the second flow channel 24 can be extruded to seal the first flow channel 14 and the second flow channel 24.

[0043] Of course, please refer to Figure 7 The seals at both ends of the first flow channel 14 and the second flow channel 24 may also be in the form of an end plate 3. Specifically, the end plate 3 is a plate-like structure, and its shape is adapted to the shape of the ends of the thawing plate located in the first flow channel 14 and the second flow channel 24. The end plate 3 can be fixedly connected to the heat exchange component 1 and the first heat storage component 2A by welding or gluing.

[0044] Of course, at the beginning of the processing and forming of the heat exchange component 1, one end thereof along the direction of the first flow channel 14 can be closed. At this time, the first flow channel 14 has only one opening, and only one end of the heat exchange component 14 needs to be sealed. The same is true for the first heat storage component 2A.

[0045] In addition, please refer to Figure 4 A protrusion or a groove is provided on the first upper plate portion 11 toward the first flow channel 14 and on the first lower plate portion 12 toward the first flow channel 14 , and the protrusion or the groove can increase the surface area of ​​the first flow channel 14 , thereby increasing the evaporation rate of the liquid refrigerant in the first flow channel 14 .

[0046] Please refer to Figures 9 and 10 , Fig. 9 A schematic structural diagram of a thawing plate according to a second embodiment of the present invention is provided; Fig.10 for Fig. 9 A schematic structural diagram of the second heat storage component;

[0047] To facilitate the description of this embodiment, the same figure marks are used for components in this embodiment that have the same structure and the same function as those in the first embodiment, and the description of the components in the first embodiment is also applicable to the second embodiment. The differences from the first embodiment are described in detail below.

[0048] In the present embodiment, the heat storage component 2 is a second heat storage component 2B, and the second heat storage component 2B is arranged at the end 15 of the heat exchange component 1. Specifically, the heat exchange component 1 includes four ends located on its four edges, and the second heat storage component 2B is fixedly connected to at least one end 15 of the two ends 15 located in the direction of the first flow channel 14 among the four ends. The following is an example in which the second heat storage component 2B is fixedly connected to the two ends 15 in the direction of the first flow channel 14. At this time, the number of second heat storage components 2B is two. It is worth noting that those skilled in the art can understand that if only one second heat storage component 2B is provided, it is also feasible to connect it to one of the two ends 15 in the direction of the first flow channel 14 of the heat exchange component 1.

[0049] In this embodiment, the heat exchange component 1 mainly includes a first upper plate portion 11 and a first lower plate portion 12. The first upper plate portion 11 is roughly a plate-shaped structure, which is roughly located above the heat exchange component 1. The first lower plate portion 12 is also roughly a plate-shaped structure, which is roughly located below the heat exchange component 1. At the same time, at least two first connecting portions 13 are provided between the first upper plate portion 11 and the first lower plate portion 12. The first connecting portion 13 simultaneously connects the first lower plate portion 12 and the first upper plate portion 11 of the heat exchange component 1 and is fixedly connected. At this time, a first flow channel 14 is formed between the first upper plate portion 11, the first lower plate portion 12 and the connecting portion 13. The heat exchange component 1 can be formed by extrusion or machining of aluminum material. Of course, the heat exchange component 1 can also be made of metals with higher thermal conductivity such as copper or stainless steel.

[0050] The second heat storage component 2B is generally tubular in structure, and a third flow channel 25 is provided inside. The third flow channel 25 is also filled with a heat storage agent or a heat storage medium with a high specific heat capacity (such as water).

[0051] Specifically, the second heat storage component 2B is provided with an opening portion 26 at one end of the third flow channel 25, and the opening portion 26 is fixedly connected to the valve core 27. In addition, the axial side wall 28 of the second heat storage component 2B is provided with an axial opening 281, and the axial opening 281 is adapted to the shape of the heat exchange component 1 at both ends along the direction of the first flow channel 14.

[0052] During specific processing, the valve core 27 can be first fixedly connected to the opening portion 26 of the second heat storage component 2B, and then the axial opening portion 281 of the second heat storage component 2B can be fixedly connected to the end portion 15 of the heat exchange component 1 along the first flow channel 14, so that the heat exchange component 1 is fixedly connected to the second heat storage component 2B, and then the heat storage agent is filled into the third flow channel 25 through the valve core 27. With this processing method, before the heat exchange component 1 is fixedly connected to the second heat storage component 2B, the first flow channel 14 of the heat exchange component 1 is sealed. The specific sealing method can refer to the first embodiment.

[0053] Specifically, the heat exchange component 1 and the second heat storage component 2B can be fixedly connected by welding or gluing. Of course, the second heat storage component 2B can also be integrally formed at the end 15 of the heat exchange component 1 in the direction of the first flow channel 14 by extrusion or turning. When the heat exchange component 1 and the second heat storage component 2B are fixedly connected by gluing, it is appropriate to use glue with higher heat conduction efficiency.

[0054] Of course, the second heat storage component 2B may also be in a form without an axial opening portion 81, that is, the axial side wall of the second heat storage component 2B is directly fixedly connected to the heat exchange component 1 at both ends along the first flow channel 14. In this case, before the heat exchange component 1 is fixedly connected to the second heat storage component 2B, the welding end of the first flow channel 14 of the heat exchange component 1 may not be sealed.

[0055] It is worth mentioning that when the second heat storage component 2B is located only at one end of the heat exchange component 1 along the direction of its first flow channel 14, the closing of the other end of the heat exchange component 1 along the direction of the first flow channel 14 (not connected to the heat storage component) can be achieved by extrusion, welding or bonding of the end plate 3, or at the beginning of the processing and forming of the heat exchange component 1, one end along the direction of the first flow channel 14 can be closed.

[0056] Of course, when the heat exchange component 1 is initially processed and formed, one end thereof is closed along the direction of the first flow channel 14, which does not conflict with the structure in which the second heat storage component 2B is provided at both ends of the heat exchange component 1 along the direction of the first flow channel 14. That is, those skilled in the art can understand that if the heat exchange component is initially designed in the form of one end being open and the other end being closed along the direction of the first flow channel 14, the above-mentioned two ends can also be fixedly connected to the axial side wall 28 of the second heat storage component 2B.

[0057] In this embodiment, the second heat storage component 2B can also provide heat for the refrigerant in the first flow channel 14, thereby relatively increasing the evaporation rate of the liquid refrigerant, providing more gaseous refrigerant, and increasing the thawing effect of the thawing plate.

[0058] It should be noted that the directional nouns such as up, down, left, and right mentioned in this embodiment are all based on the drawings in the specification and are introduced for the convenience of description; and the ordinal numbers such as "first" and "second" in the component names are also introduced for the convenience of description and do not mean any limitation on any order of the components. In addition, since the functions of some parts of the components provided in the above two embodiments are the same, this specification adopts a unified naming method for these parts.

[0059] The above is a detailed introduction to the thawing plate provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
