Description

Technical Field

[0001] This utility model relates to the field of heat exchange component technology, and more specifically, to a heat exchange component and a refrigerator having the same. Background Technology

[0002] Currently, in order to reduce the space occupied in the room, built-in refrigerators are usually embedded in the wall or cabinet, that is, their back and sides are mostly or entirely close to the wall or other furniture. This results in a small heat dissipation area, which greatly reduces the natural heat dissipation effect of the compressor compartment. The heat emitted by the refrigerator compressor can easily accumulate and cause safety hazards.

[0003] However, in order to solve the problem of heat accumulation in the compressor, the existing technology usually solves the problem of waste heat accumulation in built-in refrigerators by adding heat dissipation equipment. This method increases the overall operating power consumption of the refrigerator, and at the same time, the waste heat generated by the compressor is not utilized, which is not conducive to improving the energy efficiency of the refrigerator.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] like Figure 1 and Figure 2 As shown, Embodiment 1 of this utility model provides a heat exchange assembly, which includes a first chamber 11 and a second chamber 12. The first chamber 11 has a first mounting cavity, and the second chamber 12 has a second mounting cavity. The heat exchange assembly also includes a compressor 1 and an evaporator 2. The compressor 1 is disposed in the first mounting cavity, and the evaporator 2 is disposed in the second mounting cavity. The heat exchange assembly also includes a heat exchange pipeline 3, which is provided with a first connecting port 31 and a second connecting port 32. Both the first connecting port 31 and the second connecting port 32 are used to communicate with the first mounting cavity and are connected to a heat exchange channel formed by at least a portion of the heat exchange pipeline 3. At least a portion of the heat exchange pipeline 3 is located in the second mounting cavity to exchange heat with the heat exchange medium to be exchanged in the heat exchange channel through a cold source in the second mounting cavity.

[0053] The heat exchange assembly provided in Embodiment 1 of this utility model, by placing a portion of the heat exchange pipe 3 within the mounting cavity of the second chamber 12, i.e., the area where the evaporator 2 is located, utilizes the low-temperature characteristics of the evaporator 2 as a cold source to effectively exchange heat with the air drawn from the first chamber 11, thereby achieving the effect of cooling the air within the first mounting cavity where the compressor 1 is located. This design utilizes the evaporator 2 as the cold source for heat exchange, improving the overall energy efficiency of the system, reducing energy waste, and significantly enhancing the energy efficiency ratio of the heat exchange assembly. Furthermore, by setting the heat exchange pipe 3 between the first chamber 11 and the second chamber 12, the internal space of the heat exchange assembly is cleverly utilized, achieving effective heat transfer and utilization. The heat exchange pipe 3 replaces the bulky heat dissipation equipment, reducing the space occupied within the heat exchange assembly and helping to maintain its compact design. Therefore, the heat exchange assembly provided in this embodiment can solve the technical problem of high internal temperature of the compressor compartment in the prior art.

[0054] Specifically, the heat exchange medium is a gas.

[0055] Specifically, the heat exchange assembly also includes a third compartment 13 and a condenser 4. The third compartment 13 has a third mounting cavity, and the condenser 4 is disposed within the third mounting cavity. The heat exchange pipe 3 is also provided with a third connecting port 33, which communicates with the heat exchange channel and is connected to the third mounting cavity. After the heat exchange medium enters the heat exchange channel from the inlet, it completes heat exchange within the channel. The heat-exchanged medium then enters the third mounting cavity through the third connecting port 33 to exchange heat within the third mounting cavity. This structural arrangement, connecting the heat exchange pipe 3 to the third compartment 13, realizes a heat exchange path from the compressor compartment (equivalent to the first compartment 11) to the evaporator compartment (equivalent to the second compartment 12), and then to the condenser area (equivalent to the third compartment 13). This fully utilizes the cooled gas within the heat exchange channel, allowing it to enter the working environment of the condenser 4 and assist in its operation, thereby further improving the heat exchange efficiency of the heat exchange assembly.

[0056] In this embodiment, the heat exchange pipeline 3 includes a first pipe section 301, a second pipe section 302, and a third pipe section 303. One end of the first pipe section 301 forms a first connecting port 31, one end of the second pipe section 302 forms a second connecting port 32, and one end of the third pipe section 303 forms a third connecting port 33. The other ends of the second pipe section 302 and the third pipe section 303 are both connected to the other end of the first pipe section 301. The first connecting port 31 is located between the second connecting port 32 and the third connecting port 33. This structural arrangement subdivides the heat exchange pipeline 3 into the first pipe section 301, the second pipe section 302, and the third pipe section 303. This segmented design helps to precisely control the heat exchange process of each part and improve heat exchange efficiency. The arrangement of the first connecting port 31, the second connecting port 32, and the third connecting port 33 allows the heat exchange medium to flow along a preset path from one compartment to another, achieving multi-stage heat exchange. Specifically, the first connecting port 31 is located between the second connecting port 32 and the third connecting port 33. This arrangement ensures the rationality of the medium flow path, avoids ineffective circulation or insufficient heat exchange of the medium during the heat exchange process, and improves the utilization efficiency of thermal energy.

[0057] Specifically, at least a portion of the second pipe section 302 is located within the second compartment 12, and at least a portion of the third pipe section 303 is located within the second compartment 12. This design ensures that the medium can fully absorb the low temperature within the second compartment 12 as it passes through the heat exchange channel, achieving effective heat exchange and thereby cooling the compressor compartment and condenser area, further optimizing the thermal management of the heat exchange component system.

[0058] Specifically, at least a portion of the second pipe section 302 is a bent pipe. At least a portion of the third pipe section 303 is a bent pipe. This structural arrangement allows for increased heat exchange channel length within a limited space, improving heat exchange efficiency. Because the bent pipe path is longer and more varied, the medium experiences more heat exchange contacts as it flows through it. Compared to straight pipes, bent pipes more effectively promote heat exchange, especially within the space-constrained second compartment 12.

[0059] Specifically, one of the first connecting port 31 and the second connecting port 32 forms the inlet of the heat exchange channel, and the other forms the outlet of the heat exchange channel.

[0060] Specifically, the first connecting port 31 forms the inlet of the heat exchange channel, and the second connecting port 32 forms the outlet of the heat exchange channel. The maximum diameter of the first pipe section 301 is greater than the maximum diameter of the second pipe section 302, and the maximum diameter of the first pipe section 301 is greater than the maximum diameter of the third pipe section 303. This structural arrangement, with the maximum diameter of the first pipe section 301 being greater than the maximum diameters of the second and third pipe sections 302 and 303, optimizes the flow performance of the medium within each pipe section. The larger diameter of the first pipe section 301 helps reduce the flow resistance of the medium at the inlet, allowing the medium to enter the heat exchange channel more smoothly and improving the system's medium handling capacity. Conversely, the smaller diameters of the second and third pipe sections 302 and 303 help enhance the heat exchange efficiency of the medium during contact with the evaporator 2, because the smaller diameter means more sufficient contact between the medium and the pipe wall, thereby promoting heat exchange.

[0061] Specifically, the maximum diameter of the first pipe section 301 is greater than or equal to 50 mm and less than or equal to 60 mm. This structural design fully considers the limitations of the internal space of the heat exchange components and the balance of heat exchange performance, ensuring smooth flow of the medium when entering the heat exchange channel while avoiding the additional material costs and space occupation caused by an excessively large diameter.

[0062] Specifically, the maximum diameter of the second pipe section 302 is greater than or equal to 15 mm and less than or equal to 25 mm, and the maximum diameter of the third pipe section 303 is greater than or equal to 15 mm and less than or equal to 25 mm. This ensures both heat exchange efficiency and stable operation of the pipe sections under temperature and pressure fluctuations, avoiding system failures caused by pipe deformation or damage.

[0063] In this embodiment, the heat exchange assembly also includes a flow regulator, which is installed on the heat exchange pipeline 3 or directed toward the inlet of the heat exchange pipeline 3. The flow regulator is used to adjust the flow rate of the heat exchange medium within the heat exchange pipeline 3. This structural arrangement significantly improves the controllability and efficiency of heat exchange. By dynamically adjusting the flow rate, the flow rate of the medium can be optimized in real time according to the temperature changes in the compressor compartment, ensuring that the system achieves the best heat exchange effect under different operating conditions, effectively controlling the compressor compartment temperature, avoiding safety hazards caused by overheating, and also avoiding affecting the operating efficiency of the evaporator 2.

[0064] Specifically, the inlet of heat exchange pipeline 3 is the first connecting port 31. The flow regulating component is a fan, with the fan blades rotatably mounted at the first connecting port 31. This structural arrangement, with the fan blades rotatably mounted at the first connecting port 31, allows for precise control of the medium flow rate entering the heat exchange channel. This facilitates intelligent adjustment of the medium inflow based on real-time changes in the compressor chamber temperature, ensuring optimal heat exchange performance under different operating conditions, effectively controlling the compressor chamber temperature, avoiding safety hazards caused by overheating, and preventing any impact on the operating efficiency of the evaporator 2.

[0065] In this embodiment, the heat exchange assembly further includes a first filter, a second filter, and a third filter. All three filters are used to filter gas. The first filter is located at the first connection port 31, the second filter at the second connection port 32, and the third filter at the third connection port 33. This structural arrangement prevents dust and impurities from entering the heat exchange pipeline 3 and affecting heat exchange efficiency and the lifespan of the assembly. By installing filters at each connection port, it is ensured that the medium maintains high purity throughout its flow through the heat exchange pipeline 3, avoiding heat exchange performance degradation and system failures caused by medium contamination, and improving the stability and reliability of the heat exchange assembly operation.

[0066] Specifically, the second connection port 32 is located above the compressor 1, and the third connection port 33 is located above the condenser 4. This structural arrangement facilitates the cooling of the first chamber 11 and the third chamber 13 from top to bottom by the cooled air flowing from the second and third connection ports 32 and 33 after heat exchange. This fully utilizes the natural physical phenomenon of hot air rising and cold air sinking, leveraging gravity to achieve automatic heat dissipation without the need for additional driving devices. The cooled air formed after the medium flows through the heat exchange pipes naturally and smoothly flows towards the heat source below. This design reduces the number of mechanical moving parts in the system, lowers noise, and avoids the additional energy consumption and maintenance costs that might result from motor-driven mechanical moving parts, making the system more efficient, quieter, and easier to maintain.

[0067] Specifically, the first connection port 31 can be selectively connected to or disconnected from the second connection port 32. The heat exchange assembly also includes a control component and a temperature detection component. The temperature detection component is located inside the first mounting cavity and is used to detect the temperature inside the first mounting cavity. The control component is connected to the temperature detection component to control the connection or disconnection of the first connection port 31 and the second connection port 32 based on the detection result. This selective design of the connection or disconnection of the first connection port 31 and the second connection port 32, combined with the use of the control component and the temperature detection component, enables dynamic adjustment of the heat exchange path. The temperature detection component can monitor the temperature inside the first mounting cavity in real time, while the control component intelligently controls the connection status of the first connection port 31 and the second connection port 32 based on the detection result, ensuring efficient heat exchange when needed and timely disconnection when not needed, avoiding unnecessary energy consumption. This intelligent heat exchange path control not only improves thermal energy utilization but also optimizes the system's energy efficiency ratio, significantly improving the operating efficiency of the heat exchange assembly and achieving energy saving and emission reduction.

[0068] Specifically, the heat exchange assembly also includes a damper, which is located at the first connection port 31, and the opening degree of the damper is adjustable. This structural arrangement facilitates the adjustment of the connection or disconnection between the first connection port 31 and the second connection port 32 by adjusting the opening or closing of the damper.

[0069] Specifically, the controller is connected to the fan to control the fan blade speed based on the temperature detection results. With this setup, the controller, connected to the fan, can automatically adjust the fan blade speed based on temperature information fed back from the temperature sensor. At higher temperatures, increasing the fan speed increases the flow rate of the medium and heat exchange efficiency, quickly reducing the temperature of the compressor compartment; while when the temperature is under control, reducing the fan speed reduces unnecessary energy consumption, lowers operating noise, and improves the user experience. This temperature feedback-based fan speed control achieves intelligent and efficient heat exchange, demonstrating significant technical benefits in optimizing the internal thermodynamic cycle of heat exchange components and improving energy utilization efficiency.

[0070] Specifically, the control unit is connected to the damper to control the damper opening based on the temperature detection results. This allows the heat exchange assembly to intelligently adjust the flow rate of the medium entering the heat exchange pipeline 3 according to the actual temperature of the compressor compartment. By controlling the damper opening, the system can adjust the medium flow rate without changing the fan speed. Simultaneously, this setup facilitates more precise temperature control by coordinating the flow rate of the medium within the heat exchange pipeline 3 through the damper and fan. This adjustment mechanism improves the system's flexibility, avoids energy waste caused by excessive heat exchange, and prevents temperature control failure due to insufficient heat exchange, playing a crucial role in improving the stability and energy efficiency ratio of the heat exchange assembly.

[0071] In this embodiment, both the first chamber 11 and the second chamber 12 are connected to the heat exchange pipeline 3. The heat exchange assembly also includes a shock-absorbing buffer, which is disposed on the outer surface of the heat exchange pipeline 3. A portion of the shock-absorbing buffer is located at the connection between the first chamber 11 and the heat exchange pipeline 3, and another portion is located at the connection between the second chamber 12 and the heat exchange pipeline 3. This structural arrangement, with the shock-absorbing buffer positioned on the outer surface of the heat exchange pipeline 3, especially at the connection between the first chamber 11 and the second chamber 12 and the heat exchange pipeline 3, effectively reduces pipeline vibration and avoids noise problems caused by vibration. Simultaneously, the shock-absorbing buffer also helps extend the service life of the heat exchange pipeline 3, reduces maintenance costs, and has a positive impact on improving the overall performance of the heat exchange assembly and the user experience.

[0072] Specifically, the shock-absorbing buffer is made of sponge.

[0073] Specifically, in order to better improve the heat exchange effect, heat exchange pipeline 3 is made of copper.

[0074] Specifically, in order to extend the lifespan of the fan, it is made of heat-resistant materials.

[0075] Embodiment 2 of this utility model provides a refrigerator, which includes the heat exchange component provided in Embodiment 1.

[0076] The refrigerator provided in Embodiment 2 of this utility model, by placing a portion of the heat exchange pipe 3 within the mounting cavity of the second compartment 12, i.e., the area where the evaporator 2 is located, utilizes the low-temperature characteristics of the evaporator 2 as a cold source to effectively exchange heat with the air drawn from the first compartment 11, thereby achieving the effect of cooling the air in the first mounting cavity where the compressor 1 is located. This design utilizes the evaporator 2 as the cold source for heat exchange, improving the overall energy efficiency of the refrigerator, reducing energy waste, and significantly improving the refrigerator's energy efficiency ratio. Furthermore, by setting the heat exchange pipe 3 between the first compartment 11 and the second compartment 12, the internal space of the refrigerator is cleverly utilized, achieving effective heat transfer and utilization. The heat exchange pipe 3 replaces a bulky heat dissipation device, reducing the space occupied inside the refrigerator and helping to maintain its compact design. Therefore, the refrigerator provided in this embodiment can solve the technical problem of high internal temperature of the compressor compartment in the prior art.

[0077] like Figures 3 to 5As shown, Embodiment 3 of this utility model provides a control method for a heat exchange component. The control method for the heat exchange component is applicable to the heat exchange component provided in Embodiment 1. The control method for the heat exchange component includes: allowing gas in the first mounting cavity of the heat exchange component to flow into the heat exchange pipeline 3 of the heat exchange component through one of the first connecting port 31 and the second connecting port 32 of the heat exchange component; and after the gas has flowed through at least a portion of the heat exchange pipeline 3, allowing the gas to flow back to the first mounting cavity from the other of the first connecting port 31 and the second connecting port 32.

[0078] The control method for the heat exchange assembly provided in Embodiment 3 of this utility model allows the gas in the first mounting cavity of the heat exchange assembly to selectively flow into the heat exchange pipeline 3 through the first connecting port 31 or the second connecting port 32. This enables the absorption of waste heat from the compressor compartment to provide the heat required for auxiliary defrosting in the evaporator compartment, and also allows the use of the cold source in the evaporator compartment to dissipate heat from the compressor compartment, thus significantly improving the flexibility and efficiency of heat energy utilization. Therefore, the control method for the heat exchange assembly provided in this embodiment can solve the technical problem of high internal temperature in the compressor compartment in the prior art.

[0079] Specifically, before the gas in the first mounting cavity of the heat exchange component flows into the heat exchange pipe 3 of the heat exchange component through one of the first connecting port 31 and the second connecting port 32, the control method of the heat exchange component further includes: acquiring the actual temperature in the first mounting cavity; if the actual temperature in the first mounting cavity is greater than or equal to a preset temperature, opening the damper of the heat exchange component and rotating the fan blades of the heat exchange component; if the actual temperature in the first mounting cavity is less than the preset temperature, closing the damper and stopping the fan blades. Thus, this control method first acquires the actual temperature in the first mounting cavity, and automatically controls the state of the damper and fan based on the comparison between the actual temperature and the preset temperature. When the temperature reaches or exceeds the preset temperature, the damper opens and the fan starts, accelerating the circulation of hot air, thereby effectively absorbing waste heat from the compressor compartment and exchanging heat to prevent local overheating. Conversely, when the temperature is lower than the preset value, the damper closes and the fan stops, avoiding unnecessary energy consumption and reducing operating noise, thereby improving the system's energy efficiency and user comfort. This mechanism ensures that the heat exchange components can respond quickly when needed, enabling intelligent temperature control.

[0080] Specifically, the actual temperature inside the first mounting cavity is the maximum actual temperature inside the first mounting cavity.

[0081] Specifically, the preset temperature t1 is greater than or equal to 65°C and less than or equal to 85°C. Specifically, the preset temperature is 80°C, which is the highest ambient temperature at which the fan can maintain operation for an extended period.

[0082] Specifically, the method for rotating the fan blades of the heat exchange component includes: obtaining the difference between the actual temperature and a preset temperature within the first mounting cavity to obtain a temperature difference value; when the temperature difference value is greater than or equal to a first preset temperature difference value, rotating the fan blades at a first rotation speed; when the temperature difference value is less than the first preset temperature difference value but greater than or equal to a second preset temperature difference value, rotating the fan blades at a second rotation speed; and when the temperature difference value is less than the second preset temperature difference value, rotating the fan blades at a third rotation speed; wherein the first rotation speed is greater than the second rotation speed, and the second rotation speed is greater than the third rotation speed. By using this setting, the fan speed is set to three levels (first, second, and third rotation speeds) by calculating the temperature difference between the actual temperature and the preset temperature to adapt to different temperature difference conditions. This strategy can dynamically adjust the fan's operating intensity according to actual temperature changes. When the temperature difference is large, the fan runs at high speed to accelerate the circulation of hot air and rapidly reduce the temperature of the compressor compartment; when the temperature difference gradually decreases, the fan speed decreases accordingly, reducing energy waste. This tiered regulation strategy not only improves the accuracy of temperature control but also optimizes energy utilization, ensuring the system's efficient and economical operation.

[0083] Specifically, before the gas in the first mounting cavity of the heat exchange component flows into the heat exchange pipe 3 of the heat exchange component through one of the first connecting port 31 and the second connecting port 32, the control method of the heat exchange component further includes: obtaining the functional mode of the evaporator 2 of the heat exchange component; when the evaporator 2 is in defrosting mode, opening the damper of the heat exchange component and rotating the fan blades; when the evaporator 2 is not in defrosting mode, closing the damper and stopping the fan blades. In this way, by detecting the functional state of the evaporator 2, the operating states of the damper and fan are automatically adjusted. In defrosting mode, the damper is open and the fan is started to fully utilize the waste heat of the compressor compartment to assist the defrosting process of the evaporator 2, reducing the additional energy consumption required for defrosting and improving defrosting efficiency. In non-defrosting mode, the damper is closed and the fan is stopped, which avoids unnecessary occupation of system resources, reduces operating noise, and improves the user's quality of life. This intelligent linkage mechanism ensures efficient use of waste heat during defrosting and timely restoration to energy-saving state after defrosting, enhancing the system's intelligence and adaptability.

[0084] It should be noted that when the evaporator 2 is not in defrost mode, when the actual temperature in the first installation chamber is greater than or equal to the preset temperature, the damper of the heat exchange component is opened and the fan blades of the heat exchange component are in a rotating state.

[0085] It should be noted that, Figure 4 and Figure 5These all correspond to the heat exchange components inside the refrigerator.

[0086] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: the waste heat of the compressor compartment can be used to assist in defrosting the evaporator, reducing the burden of defrosting the steel pipe heater and saving energy; the temperature of the compressor compartment can be controlled to prevent safety accidents caused by excessively high compressor compartment temperature.

[0090] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0091] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0092] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
