Description

Technical Field

[0001] This application relates to the technical field of condensers, and more specifically, to a condenser for a thawing cabinet. Background Technique

[0002] The principle of a low-temperature and high-humidity thawing cabinet is mainly based on the principles of heat transfer and humidity control in physics, and realizes uniform thawing of food by creating a low-temperature and high-humidity environment. The low-temperature and high-humidity thawing cabinet maintains a temperature environment lower than room temperature but higher than the freezing point through an internal refrigeration system. This temperature range is usually set between 0 - 4°C. The low-temperature environment helps to slow down the spoilage rate of food during the thawing process while maintaining the nutritional components and taste of the food.

[0003] During the refrigeration process of the refrigeration system in the low-temperature and high-humidity thawing cabinet, after the refrigerant is compressed and vaporized by the compressor, it needs to dissipate its heat through the condenser and then go to the evaporator for heat exchange and refrigeration.

[0004] When the condenser in the existing low-temperature and high-humidity thawing cabinet refrigeration system is operating, when the air flow rate around the condenser is slow, the heat transfer efficiency will decrease, which easily causes the heat on the condenser to not be effectively dissipated into the surrounding air, thereby reducing the heat dissipation effect, increasing the temperature of the condenser, and even overheating. This not only affects the stable operation of the thawing cabinet, but also, when the heat dissipation of the condenser in the thawing cabinet is poor, in order to maintain the initial set thawing effect, the working load of the refrigeration system will be increased, which will further lead to an increase in the operating cost of the thawing cabinet.

[0005] In view of this, we propose a condenser for a thawing cabinet. Summary of the Invention

[0009] As an optional solution of the technical solution of this application document, the thermosensitive expansion and contraction medium is filled in one end of the inner cavity of the heat insulation outer cylinder away from the recessed groove.

[0010] As an optional solution of the technical solution of this application document, the movable part includes a heat insulation traction cover slidably sleeved on the end of the heat insulation outer cylinder; A passive heat insulation plug rod that is hermetically slidably inserted into the inner cavity of the heat insulation outer cylinder is connected to the heat insulation traction cover; A plurality of reset springs are evenly connected to the heat insulation traction cover, and the end of the reset spring away from the heat insulation traction cover is connected to the end of the recessed groove.

[0011] As an optional solution of the technical solution of this application document, the fixed end of the triggering elastic sheet is connected to the side wall of the recessed groove; The resistance structure is a resistance wire that is spirally coiled. A circle of accommodating grooves for accommodating the resistance structure is arranged on the side wall of the passive heat-insulating plug rod, and the resistance wire is spirally coiled in the inner cavity of the accommodating groove.

[0012] As an optional solution of the technical solution of this application document, the triggering spring and the resistance structure are electrically connected to the cooling fan in the airflow generating component, and when the triggering spring contacts the resistance structure, the series circuit formed by the triggering spring, the resistance structure and the cooling fan is triggered to conduct.

[0013] As an optional solution of the technical solution of this application document, the substrate structure includes a heat dissipation substrate, and the condenser pipe is fixedly connected to the side wall of the heat dissipation substrate; A heat-conducting bracket is also connected to the side of the heat dissipation substrate close to the condenser pipe.

[0014] As an optional solution of the technical solution of this application document, one end of the heat-insulating outer cylinder away from the recessed groove is connected to the side of the heat dissipation substrate away from the condenser pipeline.

[0015] As an optional solution of the technical solution of this application document, when the telescopic unit is in the initial state, the open end of the heat dissipation cover body closest to the substrate structure is covered outside the heat dissipation substrate in the substrate structure.

[0016] As an optional solution to the technical solution of the present application document, when the telescopic unit is in the initial state, under the elastic tension of the return spring in the movable part, the end of the passive thermal insulation plug rod away from the thermal insulation traction cover is in close contact with the thermal expansion medium, and the end of the thermal expansion medium away from the passive thermal insulation plug rod is in close contact with the side wall surface of the heat dissipation substrate in the substrate structure.

[0017] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. The heat dissipation area of the condenser is increased by several movable heat dissipation covers in the heat exchange component, so that the condenser can cool and dissipate heat for the condenser pipe more efficiently during operation, and when the heat dissipation effect of the heat exchange component is reduced due to the slow flow rate of the ambient air in the condenser, and the heat is continuously transferred to the thermosensitive expansion medium in the temperature-sensitive action part through the heat dissipation substrate connected to the condenser pipe. When the temperature of the condenser pipe rises to a preset critical upper limit, the volume of the thermosensitive expansion medium expands due to heat. In the process of driving the telescopic unit to extend, the resistance structure contacts the triggering spring and triggers the airflow generating component to open. The heat dissipation airflow is blown by the heat dissipation fan to the exhaust channel and passes through the heated condenser main structure, thereby forcing the air flow rate around the condenser main structure to increase, so that the cooling air can more effectively take away the heat from the surface of the condenser main structure, improve the heat dissipation efficiency, and help to quickly reduce its operating temperature.

[0018] 2. The thermosensitive expansion and contraction medium expands when heated, driving the telescopic unit to elongate. The resistance structure that moves synchronously with the passive heat insulation plug rod in the movable part of the telescopic unit, after coming into contact with the heat insulation traction cover and triggering the opening of the cooling fan, as the volume of the thermosensitive expansion and contraction medium expands, the number of turns of the coil incorporated into the series circuit formed by the triggering spring piece, the resistance structure, and the cooling fan in the resistance structure decreases, the resistance of the entire series circuit decreases, and the output power of the cooling fan increases. This helps to further increase the air flow rate around the main condenser structure, thereby taking away more heat from the surface of the main condenser structure, enabling the heated main condenser to rapidly decrease in temperature in a short time, effectively reducing the risk of damage to the condenser pipeline in the main condenser structure due to overheating, extending the service life of the equipment, and also helping to improve the stability of the operation of the thawing cabinet.

[0019] 3. The temperature of the condenser pipeline is indirectly monitored through the thermosensitive expansion and contraction medium in the temperature-sensitive actuator in contact with the heat dissipation substrate in the main condenser structure, and only after the temperature of the condenser pipeline exceeds the preset critical upper limit (i.e., the phase change temperature of the thermosensitive expansion and contraction medium), the thermosensitive expansion and contraction medium in the temperature-sensitive actuator is triggered. This enables when the temperature of the condenser pipeline is low and below the preset critical upper limit during the operation of this condenser, the air flow generating component does not operate, thus reducing unnecessary energy consumption. When the temperature of the condenser pipeline exceeds the preset critical upper limit, the air flow generating component is triggered to start, and the output power of the cooling fan in the air flow generating component can be adaptively increased as the volume of the thermosensitive expansion and contraction medium expands, thereby providing stronger heat dissipation ability, enabling the heated main condenser to rapidly decrease in temperature in a short time, effectively preventing it from overheating, and maintaining it within the optimal working temperature range.

[0020] 4. The thermosensitive expansion and contraction medium expands when heated and drives the heat dissipation cover body farthest from the heat dissipation substrate in the heat exchange component to move through the movable part in the telescopic unit. As the volume of the thermosensitive expansion and contraction medium expands, the heat dissipation cover body farthest from the heat dissipation substrate gradually drives other heat dissipation cover bodies to move away from the heat dissipation substrate through the flexible heat conduction belt, creating gaps between the heat dissipation cover body and the heat dissipation substrate and between adjacent two heat dissipation cover bodies, and exposing the originally blocked parts between the heat dissipation cover body and the heat dissipation substrate and between adjacent two heat dissipation cover bodies. These newly exposed surfaces can directly contact the flowing heat dissipation air flow and participate in the heat dissipation process, thereby further increasing the heat dissipation area, enabling more heat to be transferred to the surrounding environment through convection and radiation in the same time, and thus helping to further improve the heat dissipation efficiency.

[0021] 5. When the telescopic unit is in the initial state, several heat dissipation cover bodies are stacked, and the open end of the heat dissipation cover body closest to the substrate structure covers the outside of the heat dissipation substrate in the substrate structure. This helps to reduce the surface area of the heat exchange component exposed to the air and the chance of dust adhesion when the temperature of the condenser is low and the heat dissipation requirement is not high. When the subsequent shielding part is exposed, it can effectively avoid the situation that the heat dissipation performance of the heat exchange component decreases due to large-area dust adhesion and accumulation, thereby improving the heat dissipation stability and reliability of this condenser, effectively reducing the risk of failure of the low-temperature and high-humidity thawing cabinet, and ensuring the stable operation of the thawing cabinet.

[0037] Example 1, referring to Figure 2 , Figure 4 , Figures 8 to 11 , the embodiment of the present application provides a condenser for a thawing cabinet, including a condenser main body structure and an air flow generating component. The condenser main body structure includes a heat exchange component and a condenser pipeline 204; The air flow generating assembly includes a heat dissipation fan 206 and an exhaust passage 207 which are arranged oppositely, and the condenser main body structure is located between the heat dissipation fan 206 and the exhaust passage 207; The heat exchange assembly includes a substrate structure. The condenser pipeline 204 is connected to one side of the substrate structure. On the other side of the substrate structure, a plurality of heat dissipation cover bodies 209 are arranged side by side. A plurality of flexible heat conduction belts 214 are evenly arranged in the inner cavity of each heat dissipation cover body 209. The two ends of the flexible heat conduction belt 214 in the heat dissipation cover body 209 closest to the substrate structure are respectively connected to the substrate structure and the heat dissipation cover body 209, and the two ends of the flexible heat conduction belts 214 in the remaining heat dissipation cover bodies 209 are respectively connected to two adjacent heat dissipation cover bodies 209; On the side of the substrate structure close to the heat dissipation cover body 209, there is also a temperature-sensitive actuating member. The temperature-sensitive actuating member includes a telescopic unit. Inside the telescopic unit, there are respectively a thermosensitive expansion and contraction medium 216 and a speed control member electrically connected to the air flow generating assembly. Among them, the thermosensitive expansion and contraction medium 216 is preferably thermosensitive paraffin wax, and the phase change temperature of the thermosensitive paraffin wax is 30 - 45 °C; The telescopic unit includes a fixed part and a movable part. One end of the fixed part is connected to the side wall of the substrate structure, and the other end penetrates through a plurality of heat dissipation cover bodies 209. The movable part is elastically sleeved on one end of the fixed end far from the substrate structure and is connected to the heat dissipation cover body 209 farthest from the substrate structure; The thermosensitive expansion and contraction medium 216 is filled inside the fixed part; The speed control member includes a resistance structure 219 and a triggering elastic sheet 220 which are arranged oppositely inside the telescopic unit. The triggering elastic sheet 220 is arranged on the fixed part, and the resistance structure 219 is arranged on the movable part; Both the triggering elastic sheet 220 and the resistance structure 219 are electrically connected to the heat dissipation fan 206 in the air flow generating assembly. When the triggering elastic sheet 220 contacts the resistance structure 219, it triggers the conduction of the series circuit formed by the triggering elastic sheet 220, the resistance structure 219, and the heat dissipation fan 206; When the telescopic unit is in the initial state, the triggering elastic sheet 220 and the resistance structure 219 do not contact each other. A plurality of heat dissipation cover bodies 209 are stacked and abutted against each other, and the open end of the heat dissipation cover body 209 closest to the substrate structure covers the outside of the substrate structure; When the telescopic unit is in the initial state, under the elastic tension of the return spring 221 in the movable part, the end of the thermosensitive expansion and contraction medium 216 is closely attached to the end of the passive heat insulation plug rod 217. At this time, the triggering elastic sheet 220 and the resistance structure 219 do not contact each other. A plurality of heat dissipation cover bodies 209 are stacked and abutted against each other under the elastic tension of the return spring 221, and the open end of the heat dissipation cover body 209 closest to the substrate structure covers the outside of the substrate structure.

[0038] The heat dissipation area of the condenser is increased by a number of movable heat dissipation covers 209 in the heat exchange component, so that when the condenser is operating, it can more efficiently cool and dissipate heat from the condenser pipeline 204. And when the heat dissipation effect of the heat exchange component decreases due to the slow ambient air flow velocity of the condenser, and the heat is continuously conducted to the thermosensitive expansion medium 216 in the thermosensitive actuator through the heat dissipation substrate 205 connected to the condenser pipeline 204. When the temperature of the condenser pipeline 204 rises to the preset critical upper limit, during the process that the thermosensitive expansion medium 216 expands in volume when heated and drives the telescopic unit to elongate, the resistance structure 219 contacts the triggering elastic piece 220, and triggers the air flow generating component to start. The heat dissipation air flow is blown by the heat dissipation fan 206 to the discharge channel 207 and passes through the heated condenser main body structure, thereby can forcibly increase the air flow velocity around the condenser main body structure, make the cooling air more effectively take away the heat on the surface of the condenser main body structure, improve the heat dissipation efficiency, and help to quickly reduce its working temperature.

[0039] Referring to Figures 8 to 10 , an embodiment of the present application provides a condenser for a thawing cabinet. The fixing part includes a heat-insulating outer cylinder 215. A circle of concave grooves is provided at the end of the heat-insulating outer cylinder 215, and the thermosensitive expansion medium 216 is filled in one end of the inner cavity of the heat-insulating outer cylinder 215 far from the concave groove. Among them, the heat-insulating outer cylinder 215 is made of an insulating and heat-insulating material; One end of the heat-insulating outer cylinder 215 close to the concave groove respectively penetrates through a number of heat dissipation covers 209.

[0040] Referring to Figures 8 to 10 , an embodiment of the present application provides a condenser for a thawing cabinet. The movable part includes a heat-insulating traction cover 218 slidably sleeved on the end of the heat-insulating outer cylinder 215; A passive heat-insulating plug rod 217 which is hermetically slidably inserted into the inner cavity of the heat-insulating outer cylinder 215 is connected to the heat-insulating traction cover 218. Among them, the passive heat-insulating plug rod 217 and the heat-insulating traction cover 218 are also both made of insulating and heat-insulating materials; A plurality of return springs 221 are evenly connected to the heat-insulating traction cover 218, and one end of the return spring 221 far from the heat-insulating traction cover 218 is connected to the end of the concave groove; The fixed end of the triggering elastic piece 220 is connected to the side wall of the concave groove; The resistance structure 219 is a resistance wire arranged in a spiral winding. A circle of accommodating grooves for accommodating the resistance structure 219 is provided on the side wall of the passive heat-insulating plug rod 217, and the resistance wire is spirally wound in the inner cavity of the accommodating groove.

[0041] The thermosensitive expansion and contraction medium 216 expands when heated, driving the telescopic unit to elongate. The resistance structure 219 that moves synchronously with the passive heat insulation plug rod 217 in the movable part of the telescopic unit, after contacting the heat insulation traction cover 218 and triggering the opening of the heat dissipation fan 206, as the volume of the thermosensitive expansion and contraction medium 216 expands, the number of turns of the coil incorporated into the series circuit formed by the triggering spring piece 220, the resistance structure 219, and the heat dissipation fan 206 in the resistance structure 219 decreases, the resistance of the entire series circuit decreases, and the output power of the heat dissipation fan 206 increases. This helps to further increase the air flow rate around the condenser main body structure, thereby taking away more heat from the surface of the condenser main body structure, enabling the heated condenser main body to rapidly decrease in temperature in a short time, effectively reducing the risk of damage to the condenser pipeline 204 in the condenser main body structure due to overheating, extending the service life of the equipment, and also helping to improve the stability of the operation of the thawing cabinet.

[0042] The temperature of the condenser pipeline 204 is indirectly monitored through the thermosensitive expansion and contraction medium 216 in the temperature-sensitive action part that contacts the heat dissipation substrate 205 in the condenser main body structure. After the temperature of the condenser pipeline 204 exceeds the preset critical upper limit (i.e., the phase change temperature of the thermosensitive expansion and contraction medium 216), the thermosensitive expansion and contraction medium 216 in the temperature-sensitive action part is triggered. This enables when the temperature of the condenser pipeline 204 is low and lower than the preset critical upper limit during the operation of this condenser, the air flow generating component does not operate, thereby reducing unnecessary energy consumption. When the temperature of the condenser pipeline 204 exceeds the preset critical upper limit, the air flow generating component is triggered to start, and the output power of the heat dissipation fan 206 in the air flow generating component can be adjusted adaptively to increase as the volume of the thermosensitive expansion and contraction medium 216 expands, thereby providing a stronger heat dissipation capacity, enabling the heated condenser main body to rapidly decrease in temperature in a short time, effectively preventing it from overheating, and maintaining it within the optimal working temperature range.

[0043] Refer to Figures 2 to 6 , this embodiment of the application provides a condenser for a thawing cabinet. The substrate structure includes a heat dissipation substrate 205, and the condenser pipeline 204 is fixedly connected to the side wall of the heat dissipation substrate 205; A heat conduction support 208 is also connected to the side of the heat dissipation substrate 205 close to the condenser pipeline 204. The heat dissipation substrate 205, the heat dissipation cover body 209, and the heat conduction support 208 are all made of heat-conducting materials, and the flexible heat conduction belt 214 is made of flexible heat-conducting materials; One end of the heat insulation outer cylinder 215 away from the concave groove is connected to the side of the heat dissipation substrate 205 away from the condenser pipeline 204; When the telescopic unit is in the initial state, the open end of the heat dissipation cover body 209 closest to the substrate structure covers the outside of the heat dissipation substrate 205 in the substrate structure; When the telescopic unit is in the initial state, under the elastic tension of the return spring 221 in the movable part, one end of the passive heat insulation plug rod 217 away from the heat insulation traction cover 218 is in close contact with the thermosensitive expansion and contraction medium 216, and one end of the thermosensitive expansion and contraction medium 216 away from the passive heat insulation plug rod 217 is in close contact with the side wall surface of the heat dissipation substrate 205 in the substrate structure.

[0044] When the thermosensitive expansion and contraction medium 216 is heated and expands, it drives the heat dissipation cover body 209, which is the farthest from the heat dissipation substrate 205 in the heat exchange assembly, to move through the movable part in the telescopic unit. As the volume of the thermosensitive expansion and contraction medium 216 expands, the heat dissipation cover body 209, which is the farthest from the heat dissipation substrate 205, gradually drives other heat dissipation cover bodies 209 to move away from the heat dissipation substrate 205 through the flexible heat conduction belt 214, creating gaps between the heat dissipation cover body 209 and the heat dissipation substrate 205 and between adjacent two heat dissipation cover bodies 209, and exposing the originally blocked parts between the heat dissipation cover body 209 and the heat dissipation substrate 205 and between adjacent two heat dissipation cover bodies 209. These newly exposed surfaces can directly contact the flowing heat dissipation air flow and participate in the heat dissipation process, thereby further increasing the heat dissipation area, enabling more heat to be transferred to the surrounding environment by convection and radiation in the same time, and thus helping to further improve the heat dissipation efficiency.

[0045] When the telescopic unit is in the initial state, several heat dissipation cover bodies 209 are stacked, and the open end of the heat dissipation cover body 209 closest to the substrate structure covers the outside of the heat dissipation substrate 205 in the substrate structure. This helps to reduce the surface area of the heat exchange assembly exposed to the air when the temperature of the condenser is low and the heat dissipation demand is not high, reducing the chance of dust adhesion. Thus, when the subsequent blocked parts are exposed, it can effectively avoid the situation where the heat dissipation performance of the heat exchange assembly decreases due to large-area dust adhesion and accumulation, improving the heat dissipation stability and reliability of this condenser, effectively reducing the risk of failure of the low-temperature and high-humidity thawing cabinet, and ensuring the stable operation of the thawing cabinet.

The thawing cabinet includes a low-temperature and high-humidity thawing cabinet main body 101, on which there is a refrigeration chamber, and a refrigeration system for providing thawing cold air to the thawing chamber of the low-temperature and high-humidity thawing cabinet main body 101 is arranged in the refrigeration chamber; A dismountable cover plate 103 is hermetically connected to the position corresponding to the refrigeration chamber on the low-temperature and high-humidity thawing cabinet main body 101; The refrigeration system includes a first drainage fan 203, a compressor 212, a spiral thin tube 213 that is spirally coiled, and a fixed box 201 connected to the refrigeration chamber. Inside the cavity of the fixed box 201, an evaporation treatment box 202 is connected. Inside the end opening of the evaporation treatment box 202, a heat conduction support plate 210 is connected. On the surface of the heat conduction support plate 210, an evaporator pipeline 211 is connected. The substrate structure is fixedly connected to the space in the refrigeration chamber below the evaporation treatment box 202 through a heat conduction support 208. One end of the fixed box 201 close to the opening of the refrigeration chamber is open, and the open end of the fixed box 201 is flush with the opening end of the refrigeration chamber. When the cold air generated by the part of the evaporator pipeline 211 inside the evaporation treatment box 202 passes through the fixed box 201, the fixed box 201 blocks the transfer of the cold air to the space in the refrigeration chamber below the fixed box 201. A reserved opening for accommodating the first drainage fan 203 is provided at the top of the fixed box 201, and the first drainage fan 203 passes through the reserved opening. The first drainage fan 203 is fixedly installed on the fixed box 201, and the fixed box 201 is located above the end opening of the evaporation treatment box 202. The compressor 212 is fixedly connected inside the refrigeration chamber. The input end of the condenser pipeline 204 is connected to the output end of the compressor 212, and the output end of the condenser pipeline 204 is connected to the input end of the spiral thin tube 213. The input end of the evaporator pipeline 211 passes through the bottom of the fixed box 201 and is connected to the output end of the spiral thin tube 213. The output end of the evaporator pipeline 211 passes through the bottom of the fixed box 201 and is connected to the input end of the compressor 212. The substrate structure is fixedly connected to the inside of the refrigeration chamber through a heat conduction support 208. On the low-temperature and high-humidity thawing cabinet main body 101, there is also an air flow channel 102 connecting the refrigeration chamber and the thawing chamber. The connection part of the air flow channel and the refrigeration chamber is located above the fixed box 201. Inside the opening at one end of the air flow channel 102, there is a second drainage fan for introducing the cold air in the refrigeration chamber into the thawing chamber. Dust removal nets for preventing external dust and other impurities from entering the inside of the air flow channel 102 are provided at both ends of the air flow channel 102. On one side wall of the low-temperature and high-humidity thawing cabinet main body 101 corresponding to the position of the heat exchange component, a side hole for accommodating a heat dissipation fan 206 is provided. The heat dissipation fan 206 is inserted into the side hole, and the heat dissipation fan 206 is fixedly installed on the side wall of the low-temperature and high-humidity thawing cabinet main body 101. The discharge channel 207 is preferably an exhaust hole provided on the other side wall of the low-temperature and high-humidity thawing cabinet main body 101, and a dust removal net is also connected to the side wall of the low-temperature and high-humidity thawing cabinet main body 101 corresponding to the position of the exhaust hole.

[0047] Since the operation of the refrigeration system is a closed cycle, the operation principle of the refrigeration system is introduced starting from the condenser pipeline 204. The high-pressure refrigerant inside the condenser pipeline 204 flows from the output end of the condenser pipeline 204 into the inside of the spiral capillary 213 through the input end of the spiral capillary 213. After passing through the pressure reduction process of the spiral capillary 213, it flows into the inside of the evaporator pipeline 211 through the input end of the evaporator pipeline 211. After flowing into the inside of the evaporator pipeline 211, the boiling point of the pressure-reduced refrigerant decreases, making it easier for the refrigerant located inside the evaporator pipeline 211 to absorb heat and evaporate, and continuously absorbing the heat inside the refrigeration chamber to achieve the temperature reduction treatment of the inside of the refrigeration chamber. Then, the first diversion fan 203 delivers the cold air generated by the part of the evaporator pipeline 211 located inside the evaporation treatment box 202 to the space above the fixed box 201 in the refrigeration chamber. Then, the second diversion fan inside the air flow channel introduces the cold air in the refrigeration chamber into the thawing chamber and realizes the thawing treatment of the food in the thawing chamber.
