Description

Technical Field

[0001] This utility model relates to the field of food heat dissipation equipment technology, specifically to a heat dissipation system for a refrigeration device. Background Technology

[0002] In the food industry, including bakeries and central kitchens, stores are typically constrained by commercial space planning, resulting in compact operating areas and dense equipment layouts. Freezers, as core refrigeration equipment in bakeries and similar food businesses, require continuous operation. Bakeries primarily store temperature-sensitive ingredients and finished products such as butter, fresh dough, and pre-made desserts to ensure freshness and product quality; therefore, intermittent shutdowns cannot reduce operating time.

[0003] However, in the space-constrained setting of a bakery, the heat generated by the continuous operation of the freezer is difficult to dissipate effectively, specifically in the following two aspects:

[0004] Firstly, the refrigerator's own heat dissipation system is susceptible to environmental factors and prone to failure. The refrigerator's heat dissipation relies on heat exchange between the condenser and the outside air. However, bakeries typically have flour dust, packaging debris, and other fine impurities that easily adhere to the condenser surface, causing a reduction in condenser heat dissipation efficiency of over 30%. Simultaneously, to save space, stores often place refrigerators close to walls or adjacent to ovens, fermentation chambers, and other equipment, resulting in insufficient heat dissipation space on the sides and back of the refrigerator, obstructing airflow and further exacerbating poor heat dissipation. This not only causes the refrigerator compressor to frequently start and stop to maintain the set temperature, increasing energy costs, but also generates more extra heat, creating a vicious cycle of "poor heat dissipation → excessive heat generation."

[0005] Secondly, the local ventilation conditions in stores are inadequate for environments with multiple heat sources. In addition to freezers, bakeries also operate ovens, fermentation chambers, and other high-temperature equipment. The combined effect of multiple heat sources causes hot air to accumulate in certain areas of the store (especially around the freezers). Limited by space, most small and medium-sized bakeries lack targeted local ventilation designs: they rely solely on ordinary fresh air systems, whose air outlets are usually not specifically designed for the freezer area. This makes it difficult for hot air to effectively counteract fresh air, leading to a continuous rise in temperature around the freezers and further increasing the cooling load on the freezers.

[0006] In summary, in current bakeries with limited space, the contradiction between the continuous heat generation and insufficient heat dissipation capacity of freezers is prominent, and the existing equipment layout and ventilation design cannot effectively solve this problem, resulting in multiple issues such as increased energy consumption, accelerated equipment wear and tear, and increased risks to food storage. Utility Model Content

[0007] Therefore, there is a need to provide a heat dissipation system for refrigeration equipment to address the prominent contradiction between the continuous heat generation and insufficient heat dissipation capacity of freezers in the current space-constrained bakery stores. The existing equipment layout and ventilation design cannot effectively solve this problem, resulting in technical issues such as increased energy consumption, accelerated equipment wear and tear, and increased risks to food storage.

[0008] To achieve the above objectives, the inventors provide a heat dissipation system for a refrigeration device, comprising:

[0009] A water circulation mechanism includes a water tank, a water pump, and a circulation pipeline. The water tank is used to store water. One end of the circulation pipeline is connected to the outlet of the water tank, and the other end of the circulation pipeline is connected to the return port of the water tank. The water pump is installed on the circulation pipeline.

[0010] The heat exchange mechanism has a water-cooling channel connected to the circulation pipeline, a water tank for providing water to the heat exchange mechanism, and a heat exchange channel connected to the refrigerant circuit of the refrigeration equipment. The heat exchange mechanism is used to remove heat from the refrigerant through water-cooling heat exchange with the water source in the water tank.

[0011] The water tank, the water pump, the heat exchange mechanism, and the heat dissipation mechanism are connected to the circulation pipeline. The heat dissipation mechanism is used to dissipate heat and cool the circulating water after it has absorbed heat from the refrigerant. The water tank, the water pump, the heat exchange mechanism, and the heat dissipation mechanism are connected in sequence through the circulation pipeline.

[0012] As a preferred structure of this utility model, the heat exchange mechanism includes a heat exchange shell and a heat exchange tube. The heat exchange shell is provided with a refrigerant flow chamber, which is connected to the refrigerant circuit of the refrigeration equipment.

[0013] The heat exchange tube is disposed inside the refrigerant flow chamber, and a water flow channel is formed inside the heat exchange tube. The heat exchange tube is connected to the circulation pipeline.

[0014] As a preferred structure of this utility model, the heat exchange tube is arranged in an S-shape within the refrigerant flow chamber.

[0015] As a preferred structure of this utility model, there are multiple heat exchange tubes, which are arranged in parallel and spaced apart in the refrigerant flow chamber, and are respectively connected to the circulation pipeline.

[0016] As a preferred structure of this utility model, there are multiple heat exchange mechanisms, and the water cooling channels of the multiple heat exchange mechanisms are respectively connected to the circulation pipeline, and the heat exchange channels of the multiple heat exchange mechanisms are respectively connected to the refrigerant circuits of multiple refrigeration devices.

[0017] As a preferred structure of this utility model, the heat dissipation mechanism is located in a ventilated area of ​​the store or outdoors.

[0018] As a preferred structure of this utility model, the heat dissipation mechanism includes a tubular heat exchanger and a fan, wherein the base tube of the tubular heat exchanger is connected to the circulation pipeline, and the fan is disposed on one side of the tubular heat exchanger.

[0019] As a preferred structure of this utility model, the heat dissipation system of the refrigeration equipment further includes a water level detection mechanism, a control mechanism, and an alarm mechanism. The water level detection mechanism is located in the lower part of the water tank. The water level detection mechanism is electrically connected to the control mechanism, and the alarm mechanism is electrically connected to the control mechanism. The control mechanism is used to receive and process the detection signal of the water level detection mechanism and control the alarm mechanism to start and stop.

[0020] As a preferred structure of this utility model, the heat dissipation system of the refrigeration equipment further includes a filtration mechanism, which is disposed in the circulation pipeline between the water tank and the water pump.

[0021] As a preferred structure of this utility model, the filtration mechanism is a filter or a filter screen.

[0022] The advantages of the above technical solution, compared with existing technologies, are as follows: The heat dissipation system of this utility model's refrigeration equipment provides water to the heat exchange mechanism through a water tank in the water circulation mechanism. The heat exchange mechanism absorbs heat from the refrigerant circuit of the refrigeration equipment through water cooling. Then, an independent heat dissipation mechanism cools the circulating water that has absorbed the refrigerant heat. The cooled circulating water then returns to the water tank, forming a closed-loop heat dissipation system. By replacing traditional air cooling with water-cooled heat exchange, the high specific heat capacity of water is utilized to improve heat dissipation efficiency; the compressor start-stop frequency of the refrigeration equipment is reduced, energy consumption is lowered, equipment damage caused by high temperatures is reduced, and service life is extended; the stable cooling effect reduces the risk of food spoilage and ensures food safety.

[0062] Please see Figures 1 to 8This embodiment relates to a heat dissipation system for refrigeration equipment. It replaces traditional air-cooling with water-cooled circulating heat exchange, eliminating dependence on store space and air environment, improving heat dissipation efficiency, and reducing operational risks. Specifically, the heat dissipation system for the refrigeration equipment includes a water circulation mechanism 1, a heat exchange mechanism 2, and a heat dissipation mechanism 3. The water tank 11, the water pump 12, the heat exchange mechanism 2, and the heat dissipation mechanism 3 are sequentially connected through a circulation pipe 13 to form a closed-loop heat dissipation system. In this embodiment, the refrigeration equipment 100 is a freezer, refrigerator, etc. Details are as follows:

[0063] A water circulation mechanism 1 is a core power mechanism that achieves heat transfer through the circulation of water. The water circulation mechanism 1 includes a water tank 11, a water pump 12, and a circulation pipeline 13. The water tank 11 stores water. One end of the circulation pipeline 13 is connected to the outlet of the water tank 11, and the other end is connected to the return outlet of the water tank 11. The water pump 12 is mounted on the circulation pipeline 13. The water pump 12 is a centrifugal pump. The circulation pipeline 13 is a PVC or PE pipe, and rounded elbows are provided at the bends.

[0064] Specifically, the water tank 11 stores water (pure water or a mixture with added antifreeze and corrosion inhibitors) as a cold source reserve for the heat dissipation system. It has an outlet and a return outlet, connected to the inlet and outlet of the circulation pipe 13, respectively. The water pump 12 is mounted on the circulation pipe 13, providing power to the circulating water and driving its directional flow within the pipe to ensure continuous heat transfer. Furthermore, the circulation pipe 13 is made of corrosion-resistant material (such as stainless steel), connecting the water tank 11, water pump 12, heat exchange mechanism 2, and heat dissipation mechanism 3, forming a closed water flow channel to prevent leakage and reduce heat loss. Flexible heat transfer is achieved through the water circulation mechanism 1. Compared to traditional air convection cooling, water has a higher specific heat capacity and higher heat dissipation efficiency; the closed pipe design avoids direct contact with the store's air, unaffected by dust or space limitations.

[0065] The heat exchange mechanism 2 has a water-cooling channel connected to the circulation pipeline 13. The water tank 11 provides water to the heat exchange mechanism 2, and the heat exchange channel of the heat exchange mechanism 2 is connected to the refrigerant circuit 110 of the refrigeration equipment 100. The heat exchange mechanism 2 removes heat from the refrigerant through water-cooling heat exchange via the water source in the water tank 11. The heat exchange mechanism 2 is a device for heat exchange between the refrigerant and circulating water in the refrigeration equipment 100. It is connected to the circulation pipeline 13 via the water-cooling channel and to the refrigerant circuit 110 of the refrigeration equipment 100 via the heat exchange channel. Through direct heat exchange between water and refrigerant, the heat dissipation efficiency is improved by more than 40%. This avoids dust blockage caused by the condenser being exposed to the air in the store, reducing the frequency of equipment maintenance.

[0066] The system includes a heat dissipation mechanism 3, which is connected to the circulation pipe 13. This mechanism cools the circulating water after it has absorbed heat from the refrigerant. The water tank 11, water pump 12, heat exchange mechanism 2, and heat dissipation mechanism 3 are sequentially connected via the circulation pipe 13 to form a closed-loop cooling system. The heat dissipation mechanism 3 cools the circulating water that has absorbed heat from the refrigerant, making it reusable, and is connected to the circulation pipe 13.

[0067] Optionally, in some embodiments, such as Figure 4 and Figure 5 As shown, the heat exchange mechanism 2 includes a heat exchange shell 21 and a heat exchange tube 23. The heat exchange shell 21 has a refrigerant flow chamber 22 inside, which is connected to the refrigerant circuit 110 of the refrigeration equipment 100. The heat exchange tube 23 is disposed within the refrigerant flow chamber 22, and a water flow channel is formed inside the heat exchange tube 23. The heat exchange tube 23 is connected to the circulation pipeline 13. The refrigerant flows within the flow chamber and releases heat. The heat exchange tube 23, disposed within the refrigerant flow chamber 22, forms a water flow channel inside, and its two ends are connected to the circulation pipeline 13. Circulating water absorbs heat from the refrigerant as it flows within the heat exchange tube 23. Through direct heat exchange between water and refrigerant, the heat dissipation efficiency is increased by more than 40%. This avoids dust blockage caused by the condenser being exposed to the air in the store, reducing the frequency of equipment maintenance. The heat exchange tube 23 is made of copper.

[0068] Optionally, in some embodiments, such as Figure 4 As shown, the heat exchange tube 23 is arranged in an S-shape within the refrigerant flow chamber 22. The S-shaped arrangement of the heat exchange tube 23 increases the contact area and contact time with the refrigerant, thereby enhancing the heat exchange effect.

[0069] Optionally, in some embodiments, such as Figure 5 As shown, there are multiple heat exchange tubes 23, which are arranged in parallel and spaced apart in the refrigerant flow chamber 22. The multiple heat exchange tubes 23 are connected to the circulation pipeline 13. The parallel and spaced arrangement of the multiple heat exchange tubes 23 increases the heat exchange per unit time and ensures efficient heat transfer.

[0070] Optionally, in some embodiments, such as Figure 3As shown, there are multiple heat exchange mechanisms 2, and the water-cooling channels of each of the multiple heat exchange mechanisms 2 are respectively connected to the circulation pipe 13. The heat exchange channels of the multiple heat exchange mechanisms 2 are respectively connected to the refrigerant circuits 110 of multiple refrigeration devices 100. The extended structure supports the simultaneous connection of multiple refrigeration devices 100 to the heat dissipation system. Each heat exchange mechanism 2's water-cooling channel is connected to the circulation pipe 13, and each heat exchange channel is respectively connected to the refrigerant circuit 110 of one refrigeration device 100. Multiple devices are cooled through the same water circulation mechanism 1 and heat dissipation mechanism 3, adapting to the scenario of multiple freezers operating simultaneously in a bakery store. This eliminates the need for a separate heat dissipation system for each device, reducing equipment costs and space occupation.

[0071] Optionally, in some embodiments, such as Figure 6 and Figure 7 As shown, the heat dissipation mechanism 3 is located in a ventilated area of ​​the store or outdoors. The heat dissipation mechanism 3 is independent of the refrigeration equipment 100 body and can be installed in a ventilated area (near the store window or vent) or outdoors to avoid releasing heat to the surrounding environment of the refrigeration equipment 100 and alleviate local high temperature.

[0072] Optionally, in some embodiments, such as Figure 6 and Figure 7 As shown, the heat dissipation mechanism 3 includes a tubular heat exchanger 31 and a fan 32. The tubular heat exchanger 31 is a finned tube heat exchanger 31. The base tube 311 of the tubular heat exchanger 31 is connected to the circulation pipeline 13. After the circulating water absorbs heat and flows into the base tube 311, the heat dissipation area is expanded through the outer fins. The fan 32 is located on one side of the tubular heat exchanger 31, accelerating the airflow over the fins and dissipating the heat in the circulating water to the outside. The tubular heat exchanger 31 is installed in a ventilated location in the bakery or outdoors, near a window or vent. The fan 32 is an axial flow fan 32, which is configured in conjunction with the tubular heat exchanger 31. The combined design of the tubular heat exchanger 31 and the fan 32 improves heat dissipation efficiency, ensuring that the circulating water is cooled to the set temperature and maintaining continuous system operation.

[0073] Optionally, in some embodiments, such as Figure 2 and Figure 8As shown, the cooling system of the refrigeration equipment also includes a water level detection mechanism 4, a control mechanism 5, and an alarm mechanism 6. The water level detection mechanism 4 is located in the lower part of the water tank 11 and is electrically connected to the control mechanism 5. The alarm mechanism 6 is also electrically connected to the control mechanism 5. The control mechanism 5 receives and processes the detection signal from the water level detection mechanism 4 and controls the alarm mechanism 6 to start and stop. Specifically, the water level detection mechanism 4 monitors the water level in the water tank 11 in real time. When the detected water level is lower than a threshold, the water level detection mechanism 4 sends an electrical signal to the control mechanism 5. The control mechanism 5 identifies and processes the electrical signal and controls the alarm mechanism 6 (such as an audible and visual alarm) to start, reminding the operator to add water. This prevents the system from shutting down or the water pump 12 from running dry or being damaged due to water shortage in the water tank 11, thus improving system operational safety, reducing the frequency of manual inspections, and lowering operating costs. The water level detection mechanism 4 is a water level sensor or a level gauge, etc. The alarm mechanism 6 is an audible and visual alarm. The alarm mechanism 6 includes a PLC controller and a display element, and the PLC controller and the display element are electrically connected.

[0074] Optionally, in some embodiments, such as Figure 2 and Figure 3 As shown, the cooling system of the refrigeration equipment also includes a filter mechanism 7, which is installed in the circulation pipeline 13 between the water tank 11 and the water pump 12. The filter mechanism 7 is a device for purifying the circulating water and preventing pipeline blockage, and is installed in the circulation pipeline 13 between the water tank 11 and the water pump 12. The filter mechanism 7 is a filter or filter screen, employing a filter screen or filter element structure to filter impurities in the circulating water (such as sediment in the water tank 11 and pipeline debris), preventing impurities from entering the heat exchange tube 23 or the water pump 12, causing blockage or wear, extending the service life of the water pump 12 and the heat exchange tube 23, reducing the probability of system failure, and lowering maintenance costs.

[0075] Specifically, in this embodiment, the heat dissipation system of the cooling device, such as Figures 1 to 8 As shown, water is supplied to the heat exchange mechanism 2 via the water tank 11 of the water circulation mechanism 1. The heat exchange mechanism 2 absorbs the heat from the refrigerant circuit 110 of the refrigeration equipment 100 through water cooling. Then, the circulating water that has absorbed the heat from the refrigerant is cooled by the independent heat dissipation mechanism 3. The cooled circulating water then returns to the water tank 11, forming a closed-loop heat dissipation system. By replacing traditional air cooling with water cooling, the high specific heat capacity of water is utilized to improve heat dissipation efficiency; the compressor start-stop frequency of the refrigeration equipment 100 is reduced, energy consumption is lowered, equipment damage caused by high temperatures is reduced, and service life is extended; the stable cooling effect reduces the risk of food spoilage and ensures food safety.

[0076] The advantages of the above technical solution, which differ from existing technologies, are as follows:

[0077] Improve heat dissipation efficiency: By replacing traditional air cooling with water cooling heat exchange, the high specific heat capacity of water is utilized to improve heat dissipation efficiency by 30%-50%, reduce the compressor start-stop frequency of refrigeration equipment by 100%, and reduce energy consumption by 15%-20%.

[0078] Overcoming environmental limitations: The closed water circulation system avoids contact with the store and outdoor air, completely solving the problem of dust clogging the condenser; the heat dissipation mechanism 3 can be externally mounted, unaffected by the surrounding space of the equipment and the superposition of multiple heat sources.

[0079] Reduce operational risks: Reduce equipment wear and tear caused by high temperatures and extend its service life; stable cooling effect reduces the risk of food spoilage and ensures food safety.

[0080] Expanded application scope: It supports simultaneous heat dissipation for multiple devices and adapts to different temperature environments through the dosing mechanism, making it widely applicable to central kitchens, small catering stores and other scenarios.

[0081] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
