[0063] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0064] like Figure 1 and Figure 2As shown, embodiment 1 of the present invention provides a heat exchange component, which includes a first bin body 11 and a second bin body 12, wherein the first bin body 11 has a first installation cavity, and the second bin body 12 has a second installation cavity. The heat exchange component also includes a compressor 1 and an evaporator 2, wherein the compressor 1 is arranged in the first installation cavity, and the evaporator 2 is arranged in the second installation cavity. The heat exchange component also includes a heat exchange pipeline 3, on which a first connecting port 31 and a second connecting port 32 are arranged, wherein the first connecting port 31 and the second connecting port 32 are both used to communicate with the first installation cavity and are both connected to a heat exchange channel surrounded by at least part of the heat exchange pipeline 3; at least part of the heat exchange pipeline 3 is located in the second installation cavity, so as to perform heat exchange with the medium to be exchanged in the heat exchange channel through the cold source in the second installation cavity.

[0065] By using the heat exchange assembly provided in the first embodiment of the present invention, by setting part of the heat exchange pipeline 3 in the installation cavity of the second silo 12, that is, the area where the evaporator 2 is located, and using the low temperature characteristics of the evaporator 2 as a cold source, the air drawn from the first silo 11 can be effectively heat exchanged, thereby achieving the effect of heat dissipation and cooling of the air in the first installation cavity where the compressor 1 is located. This design uses the evaporator 2 as a cold source for heat exchange, improves the overall energy utilization efficiency of the system, reduces energy waste, and has a significant effect on improving the energy efficiency ratio of the heat exchange assembly. In addition, by setting the heat exchange pipeline 3 between the first silo 11 and the second silo 12, the space inside the heat exchange assembly is cleverly utilized, and effective heat transfer and utilization are achieved. The heat exchange pipeline 3 replaces the bulky heat dissipation equipment, reduces the occupation of the internal space of the heat exchange assembly, and helps to maintain its compact appearance design. Therefore, the heat exchange assembly provided in this embodiment can solve the technical problem of high temperature inside the compressor silo in the prior art.

[0066] Specifically, the medium to be heat exchanged is gas.

[0067] Specifically, the heat exchange component also includes a third warehouse body 13 and a condenser 4. The third warehouse body 13 has a third installation cavity, and the condenser 4 is arranged in the third installation cavity. Among them, a third connecting port 33 connected to the heat exchange channel is also arranged on the heat exchange pipeline 3, and the third connecting port 33 is connected to the third installation cavity. After the heat exchange medium enters the heat exchange channel from the inlet of the heat exchange channel, the heat exchange medium to be exchanged completes the heat exchange in the heat exchange channel, and the medium that completes the heat exchange enters the third installation cavity through the third connecting port 33 to exchange heat with the third installation cavity. With such a structural setting, the heat exchange pipeline 3 is connected with the third warehouse body 13, and the heat exchange path from the compressor compartment (equivalent to the first warehouse body 11) to the evaporator compartment (equivalent to the second warehouse body 12), and then to the condenser area (equivalent to the third warehouse body 13) is realized, and the gas cooled in the heat exchange channel is fully utilized, so that it can enter the working environment of the condenser 4 and assist the condenser to work, thereby further improving the heat exchange efficiency of the heat exchange component.

[0068] 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, one end of the third pipe section 303 forms a third connecting port 33, and 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. With such a structural setting, the heat exchange pipeline 3 is subdivided into the first pipe section 301, the second pipe section 302 and the third pipe section 303. Such a segmented design helps to accurately control the heat exchange process of each part and improve the heat exchange efficiency. The setting of the first connecting port 31, the second connecting port 32 and the third connecting port 33 enables the gas to flow along a preset path from one silo to another, thereby realizing multi-stage heat exchange. In particular, the first connecting port 31 is located between the second connecting port 32 and the third connecting port 33. This layout ensures the rationality of the medium flow path, avoids ineffective circulation of the medium or insufficient heat exchange during the heat exchange process, and improves the utilization efficiency of thermal energy.

[0069] Specifically, at least part of the second pipe section 302 is located in the second silo 12, and at least part of the third pipe section 303 is located in the second silo 12. This design ensures that the medium can fully absorb the low temperature in the second silo 12 when passing through the heat exchange channel, achieving effective heat exchange, thereby cooling the compressor silo and condenser area, and optimizing the thermal management of the system.

[0070] 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. With such a structural arrangement, the structure of the bent pipe can increase the length of the heat exchange channel in a limited space and improve the heat exchange efficiency. Since the path of the bent pipe is longer and more variable, the medium will experience more heat exchange contacts when flowing through it. Compared with a straight pipe, the bent pipe can more effectively promote heat exchange, especially in the second bin 12 with limited space.

[0071] Specifically, one of the first communication port 31 and the second communication port 32 forms an inlet of the heat exchange passage, and the other forms an outlet of the heat exchange passage.

[0072] 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 segment 301 is greater than the maximum diameter of the second pipe segment 302, and the maximum diameter of the first pipe segment 301 is greater than the maximum diameter of the third pipe segment 303. With such a structural setting, the maximum diameter of the first pipe segment 301 is greater than the maximum diameters of the second pipe segment 302 and the third pipe segment 303. This design of diameter difference can optimize the flow performance of the medium in each pipe segment. The larger diameter of the first pipe segment 301 helps to reduce the flow resistance of the medium at the inlet, so that the medium can enter the heat exchange channel more smoothly, thereby improving the medium processing capacity of the system. The smaller diameters of the second pipe segment 302 and the third pipe segment 303 help to enhance the heat exchange efficiency of the medium in the process of contacting with the evaporator 2, because the smaller diameter means that the contact between the medium and the pipe wall will be more sufficient, thereby promoting heat exchange.

[0073] 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. Such a structural setting fully takes into account the limitation of the internal space of the heat exchange component and the balance of heat exchange performance, ensuring smooth flow of the medium when entering the heat exchange channel while avoiding additional material costs and space occupation caused by an excessively large diameter.

[0074] 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. In this way, the heat exchange efficiency is guaranteed, and the pipe sections can operate stably under the condition of temperature difference changes and pressure fluctuations, avoiding system failures caused by pipe deformation or damage.

[0075] In this embodiment, the heat exchange component also includes a flow regulator, which is arranged on the heat exchange pipeline 3 or toward the inlet of the heat exchange pipeline 3, and the flow regulator is used to adjust the flow of the medium to be exchanged in the heat exchange pipeline 3. With such a structural arrangement, the controllability and efficiency of heat exchange can be significantly improved. By dynamically adjusting the flow, the flow of the medium can be optimized in real time according to the temperature change of the compressor compartment, ensuring that the system can achieve the best heat exchange effect under different working conditions, effectively controlling the compressor compartment temperature, avoiding safety hazards caused by overheating, and avoiding affecting the working efficiency of the evaporator 2.

[0076] Specifically, the inlet of the heat exchange pipeline 3 is the first connecting port 31. The flow regulating member is a fan, and the fan blade portion is rotatably disposed at the first connecting port 31. With such a structural setting, the fan blade portion is rotatably disposed at the first connecting port 31, so that it can accurately control the medium flow entering the heat exchange channel. This facilitates intelligently adjusting the inflow of the medium according to the real-time compressor chamber temperature changes, ensuring that the system can achieve the best heat exchange effect under different working conditions, effectively controlling the compressor chamber temperature, avoiding safety hazards caused by overheating, and avoiding affecting the working efficiency of the evaporator 2.

[0077] In this embodiment, the heat exchange component further includes a first filter, a second filter and a third filter, all of which are used to filter gas, the first filter is arranged at the first connecting port 31, the second filter is arranged at the second connecting port 32, and the third filter is arranged at the third connecting port 33. With such a structural arrangement, dust, impurities, etc. can be prevented from entering the heat exchange pipeline 3 and affecting the heat exchange efficiency and the service life of the component. By arranging a filter at each connecting port, it is ensured that the medium always maintains high purity during the entire process of flowing through the heat exchange pipeline 3, avoiding the decline in heat exchange performance and system failure caused by medium contamination, and improving the stability and reliability of the operation of the heat exchange component.

[0078] Specifically, the second connecting port 32 is located above the compressor 1, and the third connecting port 33 is located above the condenser 4. With such a structural arrangement, the cold air that has completed the heat exchange and flows out from the second connecting port 32 and the third connecting port 33 can cool down and dissipate heat from the first bin 11 and the third bin 13 from top to bottom. In this way, the natural physical phenomenon of hot air rising and cold air falling is fully utilized, and the cold air formed by the medium after flowing through the heat exchange pipeline can flow naturally and smoothly to the heat source below without the need for an additional driving device, thereby achieving automatic heat dissipation. This design reduces the number of mechanical moving parts in the system, reduces noise, and avoids the additional energy consumption and maintenance costs that may be caused by the mechanical moving parts driven by the motor, making the system more efficient, quiet and easy to maintain.

[0079] Specifically, the first connecting port 31 can be selectively connected or disconnected with the second connecting port 32, and the heat exchange component also includes a control part and a temperature detection part. The temperature detection part is arranged in the first installation cavity, and the temperature detection part is used to detect the temperature in the first installation cavity; the control part is connected to the temperature detection part to control the connection or disconnection of the first connecting port 31 and the second connecting port 32 according to the detection result of the temperature detection part. With such a setting, the connection or disconnection of the first connecting port 31 and the second connecting port 32 is selectively designed, and the use of the control part and the temperature detection part is combined to realize the dynamic adjustment of the heat exchange path. The temperature detection part can monitor the temperature in the first installation cavity in real time, and the control part intelligently controls the connection state of the first connecting port 31 and the second connecting port 32 according to the detection result, ensuring that the heat exchange is carried out efficiently when needed, and disconnected in time when not needed, avoiding unnecessary consumption of energy. This intelligent heat exchange path control not only improves the utilization rate of thermal energy, but also optimizes the energy efficiency ratio of the system, and has a significant effect on improving the operating efficiency of the heat exchange component and energy saving and emission reduction.

[0080] Specifically, the heat exchange assembly further includes a damper, which is arranged at the first communication port 31, and the opening of the damper is adjustable. With such a structural arrangement, it is convenient to adjust the connection or disconnection between the first communication port 31 and the second communication port 32 by adjusting the opening or closing of the damper.

[0081] Specifically, the control component is connected to the fan to control the rotation speed of the fan blade according to the detection result of the temperature detection component. With such a setting, the control component is connected to the fan, and can automatically adjust the rotation speed of the fan blade according to the temperature information fed back by the temperature detection component. When the temperature is high, increasing the fan speed can increase the flow rate and heat exchange efficiency of the medium and quickly reduce the temperature of the compressor cabin; when the temperature has been controlled, reducing the fan speed reduces unnecessary energy consumption, reduces operating noise, and improves user experience. This fan speed control based on temperature feedback realizes the intelligence and efficiency of the heat exchange process, and has significant technical effects on optimizing the internal thermal cycle of the heat exchange component and improving energy utilization efficiency.

[0082] Specifically, the control component is connected to the damper to control the opening of the damper according to the detection result of the temperature detection component. In this way, the heat exchange component can intelligently adjust the medium flow entering the heat exchange pipeline 3 according to the actual temperature of the compressor cabin. By controlling the damper opening, the system can adjust the flow of the medium without changing the fan speed. At the same time, such a setting also facilitates the coordinated allocation of the medium flow in the heat exchange pipeline 3 through the damper and the fan to achieve more precise temperature control. This adjustment mechanism improves the flexibility of the system, avoids energy waste caused by excessive heat exchange, and also prevents temperature control failure caused by insufficient heat exchange, which plays an important role in improving the stability and energy efficiency of the operation of the heat exchange component.

[0083] In this embodiment, the first bin 11 and the second bin 12 are both connected to the heat exchange pipeline 3, and the heat exchange assembly further includes a shock-absorbing buffer, which is arranged on the outer surface of the heat exchange pipeline 3, with a portion of the shock-absorbing buffer located at the connection between the first bin 11 and the heat exchange pipeline 3, and another portion located at the connection between the second bin 12 and the heat exchange pipeline 3. With such a structural arrangement, the shock-absorbing buffer is arranged on the outer surface of the heat exchange pipeline 3, especially at the connection between the first bin 11 and the second bin 12 and the heat exchange pipeline 3, which can effectively reduce pipeline vibration and avoid noise problems caused by vibration. At the same time, the shock-absorbing buffer also helps to 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 user experience.

[0084] Specifically, the shock-absorbing buffer is a sponge.

[0085] Specifically, in order to better improve the heat exchange effect, the heat exchange pipeline 3 is a copper tube.

[0086] Specifically, in order to extend the service life of the fan, the fan is made of heat-resistant material.

[0087] A second embodiment of the present invention provides a refrigerator, which includes the heat exchange assembly provided in the first embodiment.

[0088] The refrigerator provided by the second embodiment of the present invention can effectively exchange heat with the air drawn from the first warehouse 11 by setting part of the heat exchange pipeline 3 in the installation cavity of the second warehouse body 12, that is, the area where the evaporator 2 is located, and using the low temperature characteristics of the evaporator 2 as a cold source, thereby achieving the effect of dissipating heat and cooling the air in the first installation cavity where the compressor 1 is located. This design uses the evaporator 2 as a cold source for heat exchange, improves the overall energy utilization efficiency of the refrigerator, reduces energy waste, and has a significant effect on improving the energy efficiency ratio of the refrigerator. In addition, by setting the heat exchange pipeline 3 between the first warehouse body 11 and the second warehouse body 12, the space inside the refrigerator is cleverly utilized, and the effective transfer and utilization of heat is achieved. The heat exchange pipeline 3 replaces the bulky heat dissipation equipment, reduces the occupation of the internal space of the refrigerator, and helps to maintain its compact appearance design. Therefore, the refrigerator provided by this embodiment can solve the technical problem of high temperature inside the compressor compartment in the prior art.

[0089] like Figures 3 to 5As shown, embodiment three of the present invention provides a control method for a heat exchange component, and the control method for the heat exchange component is applicable to the heat exchange component provided in embodiment one, and the control method for the heat exchange component includes: allowing the gas in the first installation 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 of the heat exchange component and the second connecting port 32 of the heat exchange component; after the gas flows through at least a portion of the heat exchange pipeline 3, allowing the gas to flow back to the first installation cavity from the other of the first connecting port 31 and the second connecting port 32.

[0090] By adopting the control method of the heat exchange component provided in the third embodiment of the present invention, by making the gas in the first installation cavity of the heat exchange component selectively flow into the heat exchange pipeline 3 through the first connecting port 31 or the second connecting port 32, it is possible to absorb waste heat from the compressor compartment to provide the heat required for auxiliary defrosting to the evaporator compartment, and also to use the cold source of the evaporator compartment to dissipate heat from the compressor compartment, thereby fully improving the flexibility and efficiency of heat energy utilization. Therefore, the control method of the heat exchange component provided in this embodiment can solve the technical problem of high internal temperature of the compressor compartment in the prior art.

[0091] Specifically, before the gas in the first installation cavity of the heat exchange component flows into the heat exchange pipeline 3 of the heat exchange component through one of the first connecting port 31 of the heat exchange component and the second connecting port 32 of the heat exchange component, the control method of the heat exchange component also includes: obtaining the actual temperature in the first installation cavity; when the actual temperature in the first installation cavity is greater than or equal to the preset temperature, the damper of the heat exchange component is opened and the fan blade of the heat exchange component is in a rotating state; when the actual temperature in the first installation cavity is less than the preset temperature, the damper is closed and the fan blade is in a stationary state. In this way, the control method first obtains the actual temperature in the first installation cavity, and automatically controls the state of the damper and the 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, the fan starts, and the circulation of hot air is accelerated, thereby effectively absorbing waste heat from the compressor cabin and performing heat exchange to prevent local overheating. Conversely, when the temperature is lower than the preset value, the damper is closed and the fan stops, which avoids unnecessary energy consumption and reduces operating noise, thereby improving the energy efficiency of the system and user comfort. This mechanism ensures that the heat exchange component can respond quickly when needed, achieving intelligent temperature control.

[0092] Specifically, the actual temperature in the first installation cavity is the maximum actual temperature in the first installation cavity.

[0093] 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 t1 is 80° C., which is the highest value of the ambient temperature at which the fan can maintain long-term operation.

[0094] Specifically, the method of making the fan blade of the heat exchange component in a rotating state includes: obtaining the difference between the actual temperature in the first installation cavity and the preset temperature to obtain the temperature difference; when the temperature difference is greater than or equal to the first preset temperature difference, the fan blade is rotated at a first rotation speed; when the temperature difference is less than the first preset temperature difference and greater than or equal to the second preset temperature difference, the fan blade is rotated at a second rotation speed; when the temperature difference is less than the second preset temperature difference, the fan blade is rotated 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. With such a setting, by calculating the temperature difference between the actual temperature and the preset temperature, the fan speed is set to three levels (first, second and third rotation speeds) to adapt to different temperature difference conditions. This strategy can dynamically adjust the working intensity of the fan according to the actual temperature change. When the temperature difference is large, the fan runs at a high speed to speed up the circulation of hot air and quickly reduce the temperature of the compressor cabin; when the temperature difference gradually decreases, the fan speed is reduced accordingly to reduce energy waste. This hierarchical adjustment strategy not only improves the accuracy of temperature control, but also optimizes energy utilization, ensuring efficient and economical operation of the system.

[0095] Specifically, before the gas in the first installation cavity of the heat exchange component flows into the heat exchange pipeline 3 of the heat exchange component through one of the first connecting port 31 of the heat exchange component and the second connecting port 32 of the heat exchange component, the control method of the heat exchange component also includes: obtaining the functional mode of the evaporator 2 of the heat exchange component; when the evaporator 2 is in the defrost mode, the damper of the heat exchange component is opened and the fan blade of the heat exchange component is in a rotating state; when the evaporator 2 is not in the defrost mode, the damper is closed and the fan blade is in a stationary state. In this way, by detecting the functional state of the evaporator 2, the working state of the damper and the fan is automatically adjusted. In the defrost mode, the damper is opened and the fan is started to make full use of the residual heat of the compressor cabin, assist the defrost process of the evaporator 2, reduce the additional energy consumption required for defrosting, and improve the defrost efficiency. In the non-defrost mode, the damper is closed and the fan is stopped, which avoids the occupation of system resources in unnecessary situations, while reducing the operating noise and improving the quality of life of users. This intelligent linkage mechanism ensures efficient use of waste heat during defrosting and timely recovery to energy-saving state after defrosting, enhancing the intelligence and adaptability of the system.

[0096] It should be noted that when the evaporator 2 is not in defrost mode, when the actual temperature in the first installation cavity is greater than or equal to the preset temperature, the damper of the heat exchange component is opened and the blades of the fan of the heat exchange component are in a rotating state.

[0097] It should be noted that Figure 4 and Figure 5All correspond to the heat exchange components in the refrigerator.
