Condenser for thawing cabinet

Abstract

The present application discloses a condenser for a defrosting cabinet, belonging to the technical field of condensers. The condenser comprises a main condenser structure and an airflow generating assembly. The main condenser structure includes a heat exchange assembly and condenser piping. The airflow generating assembly includes a heat dissipation fan and an exhaust passage arranged in opposite directions. The heat exchange assembly includes a substrate structure. When the temperature of the condenser piping rises to a preset critical upper limit, the volume of the heat-sensitive expansion-contraction medium expands due to the heat. In the process of driving the telescopic unit to extend, the resistance structure contacts the triggering spring, triggering the airflow generating assembly to open. The heat dissipation airflow is blown by the heat dissipation fan to the exhaust passage and passes through the heated condenser main structure. This can force an increase in the air flow rate around the condenser main structure, allowing the cooling air to more effectively remove heat from the surface of the condenser main structure, improving heat dissipation efficiency and helping to quickly reduce its operating temperature.

Description

Technical Field

[0001] The present application relates to the technical field of condensers, and more particularly to a condenser for a thawing cabinet. Background Art

[0002] Low-temperature, high-humidity thawing cabinets operate based on the principles of heat transfer and humidity control in physics. They achieve uniform thawing of food by creating a low-temperature, high-humidity environment. Their internal refrigeration system maintains a temperature below room temperature but above freezing. This temperature range is typically set between 0-4°C. This low temperature helps slow food spoilage during the thawing process while preserving its nutritional value and taste.

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

[0004] When the condenser in the existing low-temperature and high-humidity thawing cabinet refrigeration system is in operation, when the air flow rate in the environment around the condenser is slow, the heat transfer efficiency will be reduced, which can easily lead to the heat on the condenser not being effectively dissipated to the surrounding air, thereby reducing the heat dissipation effect, causing the condenser temperature to rise, and even overheating. This not only affects the stable operation of the thawing cabinet, but also, when the condenser heats out poorly, the thawing cabinet will increase the workload of the refrigeration system in order to maintain its originally set thawing effect, thereby increasing the operating cost of the thawing cabinet.

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

[0019] The heat-insulating traction cover is connected to a passive heat-insulating plug rod which is sealingly and slidingly inserted into the inner cavity of the heat-insulating outer cylinder;

[0020] A plurality of return springs are evenly connected to the heat-insulating traction cover, and one end of the return spring away from the heat-insulating traction cover is connected to the end of the recessed groove.

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.

[0023] 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.

[0024] As an optional solution of the technical solution of this application document, the substrate structure includes a heat dissipation substrate, and the condenser pipeline is fixedly connected to the side wall of the heat dissipation substrate;

[0025] A heat-conducting bracket is also connected to the side of the heat dissipation substrate close to the condenser pipe.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 2. The thermal expansion medium drives the telescopic unit to extend when it is heated. After the resistance structure that moves synchronously with the passive insulation plug rod in the movable part of the telescopic unit contacts the insulation traction cover and triggers the cooling fan to turn on, as the volume of the thermal expansion medium expands, the number of coil turns in the series circuit formed by the triggering shrapnel, 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, which helps to further increase the air flow rate in the environment around the condenser main structure, thereby taking away more heat from the surface of the condenser main structure, so that the heated condenser main body can quickly drop in temperature in a short time, effectively reducing the risk of damage to the condenser pipes in the condenser main structure due to overheating, extending the service life of the equipment, and also helping to improve the stability of the defrost cabinet operation.

[0031] 3. The temperature of the condenser pipe is indirectly monitored by the thermal expansion medium in the temperature-sensitive action part that is in contact with the heat dissipation substrate in the condenser main structure, and the thermal expansion medium in the temperature-sensitive action part is triggered only after the condenser pipe temperature exceeds a preset critical upper limit (that is, the phase change temperature of the thermal expansion medium). As a result, when the condenser is in operation, when the condenser pipe temperature is low and lower than the preset critical upper limit, the airflow generating component does not operate, thereby reducing unnecessary energy consumption. When the condenser pipe temperature exceeds the preset critical upper limit, the airflow generating component is triggered to open, and the output power of the cooling fan in the airflow generating component can be adaptively increased as the volume of the thermal expansion medium expands, thereby providing stronger heat dissipation capacity, so that the heated condenser body can quickly drop in temperature in a short time, effectively preventing it from overheating and maintaining it within the optimal operating temperature range.

[0032] 4. The thermal expansion medium expands when heated and drives the heat dissipation cover farthest from the heat dissipation substrate in the heat exchange assembly to move through the movable part in the telescopic unit. As the volume of the thermal expansion medium expands, the heat dissipation cover farthest from the heat dissipation substrate gradually drives the other heat dissipation covers to move away from the heat dissipation substrate through the flexible conductive tape, so that gaps are generated between the heat dissipation cover and the heat dissipation substrate and between two adjacent heat dissipation covers, and the originally blocked parts between the heat dissipation cover and the heat dissipation substrate and between two adjacent heat dissipation covers are exposed. These newly exposed surfaces can directly contact the flowing heat dissipation airflow and participate in the heat dissipation process, thereby further increasing the heat dissipation area, so that more heat can be transferred to the surrounding environment through convection and radiation in the same time, thereby helping to further improve the heat dissipation efficiency.

[0033] 5. When the telescopic unit is in the initial state, several heat dissipation covers are stacked, and the open end of the heat dissipation cover closest to the substrate structure is covered on the outside of the heat dissipation substrate in the substrate structure. This makes it possible to reduce the surface area of ​​the heat exchange component exposed to the air through the heat dissipation covers stacked on each other and the heat dissipation covers covered on the outside of the heat dissipation substrate when the condenser temperature is low and the heat dissipation demand is not high, thereby reducing the chance of dust adhesion. When the shielded part is subsequently exposed, it can effectively avoid the heat exchange component from having its heat dissipation performance reduced due to large-scale dust adhesion and accumulation, thereby improving the heat dissipation stability and reliability of the condenser, and effectively reducing the risk of failure of the low-temperature and high-humidity thawing cabinet, ensuring the stable operation of the thawing cabinet.

[0051] Example 1, with reference to Figure 2 , Figure 4 , Figures 8 to 11 , an embodiment of the present application provides a condenser for a thawing cabinet, comprising a condenser main structure and an airflow generating component, wherein the condenser main structure comprises a heat exchange component and a condenser pipe 204;

[0052] The airflow generating assembly includes a heat dissipation fan 206 and an exhaust channel 207 that are arranged opposite to each other, and the condenser main structure is located between the heat dissipation fan 206 and the exhaust channel 207;

[0053] The heat exchange assembly includes a substrate structure, with the condenser pipe 204 connected to one side of the substrate structure. A plurality of heat dissipation covers 209 arranged side by side are provided on the other side of the substrate structure. Multiple flexible heat conductive belts 214 are evenly provided within the inner cavity of each heat dissipation cover 209. The ends of the flexible heat conductive belts 214 located in the heat dissipation cover 209 closest to the substrate structure are respectively connected to the substrate structure and the heat dissipation cover 209. The ends of the flexible heat conductive belts 214 located in the remaining heat dissipation covers 209 are respectively connected to two adjacent heat dissipation covers 209.

[0054] A temperature-sensitive actuating element is further provided on one side of the substrate structure near the heat dissipation cover 209. The temperature-sensitive actuating element includes a telescopic unit, the interior of which is provided with a heat-sensitive expansion and contraction medium 216 and a speed control element electrically connected to the airflow generating assembly. The heat-sensitive expansion and contraction medium 216 is preferably temperature-sensitive paraffin wax, and the phase transition temperature of the temperature-sensitive paraffin wax is 30-45°C.

[0055] The telescopic unit includes a fixed portion and a movable portion. One end of the fixed portion is connected to the side wall of the substrate structure, and the other end passes through a plurality of heat dissipation covers 209. The movable portion is elastically and movably mounted on the end of the fixed end away from the substrate structure and is connected to the heat dissipation cover 209 farthest from the substrate structure.

[0056] The heat-sensitive expansion medium 216 is filled in the interior of the fixing portion;

[0057] The speed control component includes a resistance structure 219 and a triggering spring 220 which are arranged opposite to each other in the telescopic unit. The triggering spring 220 is arranged on the fixed part, and the resistance structure 219 is arranged on the movable part.

[0058] The triggering spring 220 and the resistor structure 219 are both electrically connected to the cooling fan 206 in the airflow generating assembly. When the triggering spring 220 contacts the resistor structure 219, the series circuit formed by the triggering spring 220, the resistor structure 219, and the cooling fan 206 is turned on.

[0059] When the telescopic unit is in the initial state, the triggering spring 220 and the resistance structure 219 are not in contact with each other, and the plurality of heat dissipation covers 209 are stacked and abutted against each other, and the open end of the heat dissipation cover 209 closest to the substrate structure is covered outside the substrate structure;

[0060] 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 thermal expansion medium 216 is tightly attached to the end of the passive heat-insulating plug rod 217. At this time, the triggering spring 220 and the resistance structure 219 are not in contact with each other. Under the elastic tension of the return spring 221, several heat dissipation covers 209 are stacked and abutted against each other, and the open end of the heat dissipation cover 209 closest to the substrate structure is covered outside the substrate structure.

[0061] The heat dissipation area of ​​the condenser is increased by several movable heat dissipation covers 209 in the heat exchange component, so that the condenser can cool and dissipate heat for the condenser pipe 204 more efficiently during operation. When the heat dissipation effect of the heat exchange component is reduced due to the slow ambient air flow rate, the heat is continuously transferred to the thermal expansion medium 216 in the temperature-sensitive action part through the heat dissipation substrate 205 connected to the condenser pipe 204. When the temperature of the condenser pipe 204 rises to a preset critical upper limit, the thermal expansion medium 216 expands due to heat. In the process of driving the telescopic unit to extend, the resistance structure 219 contacts the triggering spring 220, and triggers the airflow generating component to open. The heat dissipation airflow is blown by the heat dissipation fan 206 to the exhaust channel 207 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.

[0062] Reference Figures 8 to 10 The embodiment of the present application provides a condenser for a thawing cabinet, wherein the fixing portion includes a heat-insulating outer cylinder 215, the end of which is provided with a circle of recessed grooves, and a heat-sensitive expansion and contraction medium 216 is filled in the end of the inner cavity of the heat-insulating outer cylinder 215 away from the recessed grooves, wherein the heat-insulating outer cylinder 215 is made of an insulating material;

[0063] One end of the heat-insulating outer cylinder 215 close to the concave groove passes through a plurality of heat-dissipating covers 209 .

[0064] Reference Figures 8 to 10 , the embodiment of the present application provides a condenser for a thawing cabinet, wherein the movable portion includes a heat-insulating traction cover 218 slidably sleeved on the end of a heat-insulating outer cylinder 215;

[0065] The heat-insulating traction cover 218 is connected to a passive heat-insulating plug rod 217 that is sealingly and slidably inserted into the inner cavity of the heat-insulating outer cylinder 215. The passive heat-insulating plug rod 217 and the heat-insulating traction cover 218 are also made of insulating materials.

[0066] A plurality of return springs 221 are evenly connected to the heat-insulating traction cover 218, and one end of the return spring 221 away from the heat-insulating traction cover 218 is connected to the end of the recessed groove;

[0067] The fixed end of the triggering spring 220 is connected to the side wall of the recessed groove;

[0068] The resistance structure 219 is a resistance wire that is spirally wound. A groove that can accommodate the resistance structure 219 is formed on the side wall of the passive thermal insulation plug rod 217, and the resistance wire is spirally wound in the inner cavity of the groove.

[0069] The thermal expansion medium 216 expands due to heat, driving the telescopic unit to extend. After the resistance structure 219 that moves synchronously with the passive insulation plug rod 217 in the movable part of the telescopic unit contacts the insulation traction cover 218 and triggers the cooling fan 206 to turn on, as the volume of the thermal expansion medium 216 expands, the number of coil turns in the series circuit formed by the triggering spring 220, the resistance structure 219 and the cooling fan 206 in the resistance structure 219 decreases, the resistance of the entire series circuit decreases, and the output power of the cooling fan 206 increases, which helps to further increase the air flow rate in the environment around the condenser main structure, thereby taking away more heat from the surface of the condenser main structure, so that the heated condenser main body can quickly drop in temperature in a short time, effectively reducing the risk of damage to the condenser pipe 204 in the condenser main structure due to overheating, extending the service life of the equipment, and also helping to improve the stability of the thawing cabinet operation.

[0070] The temperature of the condenser pipe 204 is indirectly monitored by the thermal expansion medium 216 in the thermal-sensitive actuating member in contact with the heat dissipation substrate 205 in the condenser main structure, and the thermal expansion medium 216 in the thermal-sensitive actuating member is triggered only after the temperature of the condenser pipe 204 exceeds a preset critical upper limit (that is, the phase change temperature of the thermal expansion medium 216). This allows the condenser to be operated. When the temperature of the condenser pipe 204 is low and below the preset critical upper limit, the airflow generating component does not operate, thereby reducing unnecessary energy consumption. When the temperature of the condenser pipe 204 exceeds the preset critical upper limit, the airflow generating component is triggered to turn on, and the output power of the heat dissipation fan 206 in the airflow generating component can be adaptively increased as the volume of the thermal expansion medium 216 expands, thereby providing stronger heat dissipation capacity, so that the temperature of the heated condenser body can drop rapidly in a short period of time, effectively preventing it from overheating and maintaining it within the optimal operating temperature range.

[0071] Reference Figures 2 to 6 , the embodiment of the present application provides a condenser for a thawing cabinet, the substrate structure includes a heat dissipation substrate 205, and the condenser pipe 204 is fixedly connected to the side wall of the heat dissipation substrate 205;

[0072] A heat-conducting bracket 208 is also connected to the side of the heat dissipation substrate 205 close to the condenser pipe 204. The heat dissipation substrate 205, the heat dissipation cover 209 and the heat-conducting bracket 208 are all made of heat-conducting materials, and the flexible heat-conducting belt 214 is made of flexible heat-conducting materials.

[0073] One end of the heat-insulating outer cylinder 215 away from the concave groove is connected to the side of the heat-dissipating substrate 205 away from the condenser pipe 204;

[0074] When the telescopic unit is in the initial state, the open end of the heat dissipation cover 209 closest to the substrate structure is covered outside the heat dissipation substrate 205 in the substrate structure;

[0075] 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 passive thermal insulation plug rod 217 away from the thermal insulation traction cover 218 is in close contact with the thermal expansion medium 216, and the end of the thermal expansion medium 216 away from the passive thermal insulation plug rod 217 is in close contact with the side wall surface of the heat dissipation substrate 205 in the substrate structure.

[0076] The thermal expansion medium 216 expands when heated and drives the heat dissipation cover 209 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 thermal expansion medium 216 expands, the heat dissipation cover 209 farthest from the heat dissipation substrate 205 gradually drives the other heat dissipation covers 209 to move away from the heat dissipation substrate 205 through the flexible conductive belt 214, so that gaps are generated between the heat dissipation cover 209 and the heat dissipation substrate 205 and between two adjacent heat dissipation covers 209, and the previously blocked portions between the heat dissipation cover 209 and the heat dissipation substrate 205 and between two adjacent heat dissipation covers 209 are exposed. These newly exposed surfaces can directly contact the flowing heat dissipation airflow and participate in the heat dissipation process, thereby further increasing the heat dissipation area, so that more heat can be transferred to the surrounding environment through convection and radiation in the same time, thereby helping to further improve the heat dissipation efficiency.

[0077] When the telescopic unit is in the initial state, several heat dissipation covers 209 are stacked, and the open end of the heat dissipation cover 209 closest to the substrate structure is covered on the outside of the heat dissipation substrate 205 in the substrate structure. This makes it possible to reduce the surface area of ​​the heat exchange component exposed to the air through the heat dissipation covers 209 stacked on each other and the heat dissipation cover 209 covered on the outside of the heat dissipation substrate 205 when the condenser temperature is low and the heat dissipation demand is not high, thereby reducing the chance of dust adhesion. When the shielded part is subsequently exposed, it can effectively avoid the heat exchange component from having its heat dissipation performance reduced due to large-scale dust adhesion and accumulation, thereby improving the heat dissipation stability and reliability of the condenser, and effectively reducing the risk of failure of the low-temperature and high-humidity thawing cabinet, ensuring the stable operation of the thawing cabinet.

[0090] The exhaust channel 207 is preferably an exhaust hole arranged on the other side wall of the low-temperature and high-humidity thawing cabinet body 101, and a dust removal net is also connected to the side wall of the low-temperature and high-humidity thawing cabinet body 101 corresponding to the exhaust hole position.

[0091] Since the operation of the refrigeration system is a closed cycle, the operating principle of the refrigeration system is introduced starting from the condenser pipe 204. The high-pressure refrigerant inside the condenser pipe 204 flows from the output end of the condenser pipe 204 through the input end of the spiral tube 213 into the interior of the spiral tube 213. After being depressurized by the spiral tube 213, it flows into the interior of the evaporator pipe 211 through the input end of the evaporator pipe 211. The refrigerant that has undergone depressurization treatment has its boiling point reduced after flowing into the interior of the evaporator pipe 211, making it easier for the refrigerant inside the evaporator pipe 211 to absorb heat and evaporate, and continuously absorb heat inside the refrigeration chamber to achieve cooling treatment inside the refrigeration chamber. The first suction fan 203 then transports the cold air generated by the internal part of the evaporator pipe 211 located in the evaporation treatment box 202 to the space above the fixed box 201 in the refrigeration chamber, and the second suction fan inside the air flow channel then introduces the cold air in the refrigeration chamber into the thawing chamber, thereby achieving thawing treatment of the food in the thawing chamber.
