Description
Technical Field
[0001] This application relates to the field of air conditioning technology, such as a heat-conducting element for a compressor, a heat dissipation assembly, a compressor assembly, and an outdoor unit for an air conditioner. Background Technology
[0002] When an air conditioner is cooling, the compressor compresses the refrigerant, increasing the temperature and pressure of the gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant releases heat and condenses into a liquid state in the condenser. The liquid refrigerant then passes through a throttling device and enters the evaporator, where it evaporates and absorbs heat.
[0003] In high-temperature environments, the compressor's suction and discharge temperatures are both high. Excessive compressor temperature can trigger the system's overheat protection, causing the air conditioner to stop cooling. Furthermore, excessively high compressor suction temperature can also lead to a decrease in the overall COP of the refrigeration system.
[0004] To ensure a high cooling capacity of the compressor even in high-temperature environments, a related technology discloses an air conditioner. The air conditioner includes a compressor with a return pipe connected to its suction port; an auxiliary heat exchanger and a coil. The auxiliary heat exchanger includes a first port, a second port, a third port, and a fourth port. A first refrigerant flow path is formed between the first and second ports, and a second refrigerant flow path is formed between the third and fourth ports. The refrigerant in the first and second flow paths can exchange heat with the refrigerant in the second flow path. The first and second ports are respectively connected to the compressor's return pipe, and the third and fourth ports are respectively connected to both ends of the coil. The coil is mounted on the compressor housing and is filled with refrigerant. This air conditioner improves the compressor's heat dissipation effect by incorporating an auxiliary heat exchanger and a coil.
[0005] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0006] After using coils to lower the compressor temperature, the compressor's intake temperature will increase accordingly, leading to an increase in the compressor's exhaust temperature. Therefore, the compressor's heat dissipation effect needs to be further improved. Summary of the Invention

[0065] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0066] When an air conditioner is running, the compressor compresses the refrigerant, raising its temperature, and then discharges the heated and pressurized refrigerant from the compressor's exhaust. As the compressor runs, its temperature also rises. This is especially noticeable under high-temperature cooling conditions, where the compressor's temperature increase is more pronounced due to the higher suction temperature. When the compressor temperature is high, it is prone to triggering its high-temperature protection mechanism and shutting down. This compressor shutdown results in interrupted cooling, manifesting as poor high-temperature cooling capacity.
[0067] To enable the compressor to operate continuously in high-temperature environments, some air conditioners employ cooling measures to reduce the likelihood of the compressor triggering its overheat protection mechanism. However, during the initial startup phase, the compressor's discharge temperature is relatively low. Lowering the compressor's temperature at this time can easily cause the refrigerant inside the compressor to form liquid droplets under high pressure and low temperature conditions. The presence of liquid refrigerant inside the compressor can lead to liquid slugging, potentially damaging the compressor. Furthermore, when the air conditioner is running in heating mode, the cooling effect on the compressor causes heat dissipation in the system, affecting the air conditioner's heating efficiency.
[0068] A related technology discloses an air conditioner including a compressor with a return pipe connected to its suction port; an auxiliary heat exchanger and a coil. The auxiliary heat exchanger includes a first port, a second port, a third port, and a fourth port. A first refrigerant flow path is formed between the first and second ports, and a second refrigerant flow path is formed between the third and fourth ports. The refrigerant in the first and second refrigerant flow paths can exchange heat with the refrigerant in the second refrigerant flow path. The first and second ports are respectively connected to the compressor's return pipe, and the third and fourth ports are respectively connected to both ends of the coil. The coil is mounted on the compressor housing and is filled with refrigerant. This related technology improves the compressor's heat dissipation effect by incorporating an auxiliary heat exchanger and a coil.
[0069] The problem with this technology is that cooling the compressor increases its suction temperature. In the overall refrigerant circulation system, the heat dissipated from the compressor returns to the compressor along with the suction, which limits the compressor's heat dissipation.
[0070] To improve the cooling effect of the compressor and reduce or avoid liquid slugging caused by poor compressor cooling, combined with Figures 1 to 13 As shown, this embodiment of the present disclosure provides a heat-conducting element for a compressor 20. The heat dissipation element 620 includes a heat dissipation body 100, which is configured with a filling space filled with refrigerant. The filling space is a sealed space, and the filling pressure of the refrigerant is a first pressure to make the refrigerant evaporate at a first temperature. When the heat dissipation body 100 is at the first temperature, the heat-conducting element automatically starts.
[0071] In this embodiment, the compressor temperature indicates the operating status of compressor 20. If the compressor 20 temperature is low, liquid slugging is likely to occur inside compressor 20, and compressor 20 may fail to reach its optimal operating temperature range. The discharge temperature of compressor 20 is the temperature of the refrigerant measured near the refrigerant outlet of compressor 20. The discharge temperature of compressor 20 characterizes the internal temperature of compressor 20. In some cases, the discharge temperature of compressor 20 can also characterize the operating temperature of compressor 20, and the discharge temperature and compressor 20 temperature can be converted.
[0072] The heat-conducting element is set for the compressor 20. After the heat-conducting element is started, it transfers the heat of the compressor 20 to the environment where the compressor 20 is located, thereby reducing the temperature of the compressor 20.
[0073] If the temperature of compressor 20 is greater than or equal to the first preset temperature, it is considered that the operating temperature of compressor 20 is too high. When compressor 20 is running at this temperature or higher, it is prone to poor lubrication, damage to compressor 20, or triggering overheat protection shutdown.
[0074] In operation, the heat-conducting element is in heat-transfer contact with the compressor 20. When the temperature of the compressor 20 is greater than or equal to the first preset temperature, the temperature of the heat-conducting element is also greater than or equal to the first preset temperature.
[0075] The heat-conducting element provided in this embodiment can automatically start when the compressor 20 temperature is greater than or equal to a first preset temperature. This avoids affecting the lubrication effect of the compressor 20 when the compressor 20 temperature is low, and can also dissipate heat from the compressor 20 when the compressor 20 temperature is high, thereby enabling the compressor 20 to operate in isothermal compression or near-isothermal compression mode. Since the start-up of the heat-conducting element is spontaneous, no additional start-up control components are required, resulting in a low-cost and reliable method for controlling the temperature of the compressor 20.
[0076] Isothermal compression is a relatively ideal operating condition. The isothermal compression described in this embodiment is a near-isothermal compression situation. When the compressor 20 operates in isothermal compression mode, it compresses the refrigerant and can transfer the heat generated by compression to outside the refrigerant circulation system, thereby reducing or eliminating the temperature rise of the refrigerant while its volume decreases and its pressure increases. This form of compression can reduce the internal energy of the refrigerant, allowing it to absorb more heat during its evaporation and expansion in the condenser.
[0077] Using the heat-conducting element provided in this embodiment, the heat-conducting element does not dissipate heat from the compressor 20 during the initial startup phase, allowing the compressor 20 to quickly reach its optimal operating temperature range. When the air conditioner is running in cooling mode, the heat-conducting element allows the compressor 20 to operate in near-isothermal compression mode after it has stabilized, improving the air conditioner's high-temperature cooling capacity. When the air conditioner is running in heating mode, the heat-conducting element does not activate, and the heat generated by the compressor 20 compressing the refrigerant is not dissipated into the environment surrounding the compressor 20, thus improving the compressor 20's heating capacity.
[0078] Optionally, the refrigerant may include water, and the first pressure may be greater than or equal to 40 kPa and less than or equal to 80 kPa.
[0079] Water has a boiling point between 35 and 80°C under pressure conditions of 40 kPa to 80 kPa. Correspondingly, the starting temperature of the heat-conducting element is greater than 35°C. Thus, the starting temperature of the heat-conducting element is above the condensation temperature of most refrigerants. Dissipating heat from the compressor 20 above this temperature can prevent or reduce the condensation of refrigerant within the compressor 20, thus preventing liquid slugging. The starting temperature of the heat-conducting element is less than 80°C, which can mitigate or prevent the compressor 20 from overheating and causing the heat-conducting element to start up late.
[0080] Optionally, the first pressure is greater than or equal to 47 kPa and less than or equal to 70 kPa.
[0081] Furthermore, under pressure conditions of 47 kPa to 70 kPa, the boiling point of water is between 45 and 70 degrees Celsius. Correspondingly, the starting temperature of the heat-conducting element is greater than or equal to 45 degrees Celsius. This further reduces liquid slugging inside the compressor 20 due to its low initial startup temperature. Additionally, it allows the heat-conducting element to start earlier to dissipate heat from the compressor 20.
[0082] Optionally, the refrigerant charge ratio is greater than or equal to 30% and less than or equal to 50%.
[0083] If the refrigerant charge ratio is too low, the heat-conducting element may dry out under high-temperature operating conditions, meaning excessive refrigerant evaporation cannot be replenished in time, affecting the heat transfer performance of the heat-conducting element. If the charge ratio is too high, the refrigerant flow inside the heat-conducting element may be obstructed, affecting the heat transfer efficiency of the heat-conducting element. At this charge ratio, the evaporation and condensation processes of the refrigerant can proceed efficiently, the heat conduction efficiency of the heat-conducting element is high, and the heat pipe start-up time is short.
[0084] Optionally, the refrigerant may include deionized water.
[0085] Deionized water is an excellent heat transfer medium. Due to its high specific heat capacity and high thermal conductivity, it can effectively absorb and transfer heat, thereby improving the thermal conductivity of heat-conducting elements. Deionized water removes ions from the water, reducing corrosion and scaling problems that may occur when water circulates in the system, which helps extend the service life of heat-conducting elements. Deionized water leaks or other accidental incidents have a smaller environmental impact.
[0086] The selection of the first preset temperature is crucial for ensuring that compressor 20 can operate in isothermal compression and for reducing condensation within compressor 20. If the first preset temperature is too low, it cannot be adequately guaranteed that compressor 20 will not experience liquid slugging during initial startup, and it will be difficult to keep the lubricating oil of compressor 20 at its optimal operating temperature. If the first preset temperature is too high, compressor 20 will only be able to operate in isothermal compression at higher temperatures, which will weaken the high-temperature cooling capacity of the air conditioner.
[0087] In order to keep the first preset temperature within a reasonable range, as an optional implementation, the first preset temperature is positively correlated with the protection temperature of the compressor 20.
[0088] The protection temperature of compressor 20 characterizes its operating temperature range. A higher protection temperature means the optimal operating temperature range of compressor 20 is in a higher temperature range. In this case, the first preset temperature is also correspondingly higher, which can reduce or prevent liquid slugging in compressor 20. A lower protection temperature means the optimal operating temperature range of compressor 20 is in a lower temperature range. In this case, the first preset temperature is also correspondingly lower, which can increase the operating temperature range of compressor 20 after stable operation to approach isothermal compression operation.
[0089] It should be noted that the first preset temperature is lower than the protection temperature of compressor 20. In this way, before compressor 20 reaches the protection temperature, the heat-conducting element is activated to dissipate heat from compressor 20, thereby reducing the number of times compressor 20 stops due to reaching the protection temperature.
[0090] Optionally, the first temperature is greater than or equal to 80 degrees Celsius and less than or equal to 90 degrees Celsius.
[0091] For air conditioners operating in high-temperature environments, the extreme high-temperature environment temperature is 53°C, and the condensing temperature is between 63°C and 73°C. Correspondingly, the discharge temperature of compressor 20 is approximately between 80°C and 90°C. Considering the operating environment of compressor 20, the lubricating oil in compressor 20 achieves better lubrication between 80°C and 90°C. Accordingly, setting the starting temperature of the heat-conducting element between 80°C and 90°C allows for better thermal management of compressor 20 under high-temperature cooling conditions, ensuring good lubrication while allowing compressor 20 to operate in a near-isothermal compression manner.
[0092] Inside the heat-conducting element, efficient heat transfer relies on the gas-liquid two-phase circulation of the refrigerant. Optionally, this can be achieved by combining... Figure 6 As shown, the filling space includes a first channel 111 and a second channel 112. The first channel 111 of the filling space is configured such that capillary action can occur in the liquid refrigerant in the first channel 111, and the second channel 112 of the filling space is suitable for the passage of gaseous refrigerant.
[0093] In this configuration, the heat dissipation body 100 is shaped like a capillary heat pipe. Specifically, the filling space is constructed with a first channel 111 and a second channel 112. In a preferred embodiment, the heat dissipation body 100 includes at least one flat tube, with the middle portion serving as the second channel 112 and the edge portion serving as the first channel 111. After evaporation, the gaseous refrigerant near the compressor 20 flows through the second channel 112 towards the end away from the compressor 20. After condensation at the end away from the compressor 20, the gaseous refrigerant returns to the end near the compressor 20 through the first channel 111 under capillary action. This reciprocating cycle rapidly removes the heat emitted by the compressor 20.
[0094] This setup has lower requirements for the arrangement of heat-conducting elements, and the structure of the heat dissipation body 100 is simple and easy to process.
[0095] Optionally, combined Figure 7 As shown, the filling space includes a ring-shaped pipe 120, in which the refrigerant is distributed in the ring-shaped pipe 120 in the form of alternating gas and liquid columns.
[0096] In this configuration, the heat dissipation unit 100 is similar to a pulsating heat pipe. Specifically, the liquid column near the compressor 20 evaporates into a gaseous state, pushing the remaining liquid column towards the compressor 20. The gas column away from the compressor 20 condenses into a liquid state. The compressor 20 is cooled through the two-phase change and movement of the gas and liquid columns. This arrangement prevents the heat-conducting element from drying out, facilitating continuous heat dissipation from the compressor 20. Furthermore, the heat transfer capacity of this type of heat-conducting element increases with the heat load. In other words, the heat dissipation capacity of the heat-conducting element can adapt to the heat dissipation requirements of the compressor 20.
[0097] Optionally, combined Figure 8 As shown, the filling space includes an evaporation section 131 and a condensation section 132, with the height of the condensation section 132 being greater than the height of the evaporation section 131.
[0098] In this configuration, the heat dissipation unit 100 is shaped like a gravity heat pipe. Specifically, the refrigerant charging space includes a higher condensation section 132 and a lower evaporation section 131. The lower evaporation section 131 is closer to the compressor 20, while the higher condensation section 132 is farther from the compressor 20. Liquid refrigerant flows back to the position near the compressor 20 under gravity, then absorbs heat and evaporates. Gaseous refrigerant moves upward to the evaporation section 131 due to the density difference, and condenses and releases heat at a position far from the compressor 20. The condensed liquid refrigerant then returns to the position near the compressor 20 under gravity. Through this reciprocating cycle, the heat generated by the compressor 20 is continuously removed. With this configuration, the heat dissipation unit 100 provides more reliable heat dissipation for the compressor 20.
[0099] Optionally, the filling space is filled with a porous material, the gaps inside the porous material allowing the refrigerant to undergo capillary action.
[0100] The gaseous refrigerant moves from the pores of the porous material to the heat release end, where it condenses and is driven by capillary force to the evaporation section. This reciprocating cycle removes heat from the compressor 20. Because the filling space is filled with porous material, the structural strength of the heat-conducting element is improved, making it less prone to deformation or damage.
[0101] Optionally, the heat-conducting element includes a heat-absorbing part 200 and a heat-dissipating part 300, wherein the heat-absorbing part is in heat transfer contact with the heat dissipation object; the heat dissipating part 300 is heat-transferringly connected to the heat-absorbing part 200; wherein the filling space is constructed in the heat-absorbing part 200 and / or the heat dissipating part 300.
[0102] The heat-conducting element is used to dissipate heat from the compressor 20, and the object of heat dissipation is the compressor 20. For heat dissipation of the compressor 20, the heat dissipation body 100 has at least two functions: firstly, to fully absorb the heat from the compressor 20; and secondly, to dissipate the heat. Therefore, the heat dissipation body 100 has at least a heat-absorbing part 200 and a heat-dissipating part 300. The heat-absorbing part 200 is used to make full contact with the compressor 20, and the heat dissipating part 300 is used to conduct and dissipate the heat absorbed by the heat-absorbing part 200.
[0103] Optionally, the heat-absorbing part 200 and the heat-dissipating part 300 are an integral structure.
[0104] This configuration improves the sealing performance and structural strength of the heat-conducting element, and facilitates its assembly.
[0105] Optionally, the heat-absorbing part 200 and the heat-dissipating part 300 are formed by bending an inflated plate.
[0106] The inside of the inflatable plate can be configured to allow for the flow of refrigerant. This design results in a smaller heat-conducting element with better heat transfer performance.
[0107] Optionally, the filling space includes an evaporation section 131 and a condensation section 132, with the evaporation section 131 located in the heat absorption section 200 and the condensation section 132 located in the heat dissipation section 300.
[0108] In this configuration, the refrigerant evaporates and absorbs heat in the heat-absorbing section 200 of the heat-conducting element, and releases heat and condenses in the heat-dissipating section 300 of the heat-conducting element. This is beneficial for system design and also ensures that the heat dissipation of the compressor 20 by the heat-conducting element can be continuous.
[0109] Optionally, combined Figure 13As shown, the heat dissipation part 300 includes a heat conduction element 310 and a heat dissipation element 320, wherein the heat dissipation element 320 is connected to the heat absorption part 200 through the heat conduction element 310 for heat transfer.
[0110] The heat dissipation section 300 includes a heat conduction element 310 and a heat dissipation element 320, which can be disposed at a position away from the heat absorption section 200. For example, when the compressor 20 is installed in the compressor compartment, the heat dissipation element 320 can be installed in the heat exchanger compartment of the air conditioner and outside the air conditioner, regardless of the location of the compressor 20.
[0111] This configuration allows the heat-conducting element to dissipate heat through the heat dissipation section 300, and provides more possibilities for the heat dissipation method of the heat-conducting element.
[0112] Optionally, one end of the heat conduction element 310 is connected to one of the heat absorption part 200 and the heat dissipation part 320, and the other end overlaps with the other of the heat absorption part 200 and the heat dissipation part 320. The heat conduction element 310 can be controlled to disconnect from the heat absorption part 200 or the heat dissipation part 300.
[0113] As another way to achieve self-starting of the heat-conducting element at a temperature greater than or equal to a first preset temperature, the heat-conducting element 310 of the heat dissipation section 300 is in the form of controlled movement. The heat-conducting element 310 transfers heat through thermal conductivity, with its two ends connected to the heat-absorbing section 200 and the heat dissipation section 320, respectively. When both ends of the heat-conducting element 310 are properly connected, the heat absorbed by the heat-absorbing section 200 can be conducted to the heat dissipation section 320 through the heat-conducting element 310; when at least one end of the heat-conducting element 310 is disconnected, the heat dissipation section 320 cannot dissipate the heat absorbed by the heat-absorbing section 200. This configuration also allows for relatively convenient starting and stopping of the heat-conducting element.
[0114] Optionally, when the heat-conducting element is constructed with a filling space: the filling space is constructed in the heat-absorbing part 200; and / or, the filling space is constructed in the heat-conducting part 310; and / or, the filling space is constructed in the heat-dissipating part 320.
[0115] When the filling space is constructed in one of the heat-absorbing part 200, the heat-conducting member 310, and the heat-dissipating part 300, the heat transfer efficiency of one stage from the compressor 20 to the surrounding environment can be enhanced. When the filling space is constructed in two of the heat-absorbing part 200, the heat-conducting member 310, and the heat-dissipating part 300, the heat transfer efficiency of both stages from the compressor 20 to the surrounding environment can be enhanced. When the filling space is constructed in the heat-absorbing part 200, the heat-conducting member 310, and the heat-dissipating part 300, the heat transfer efficiency of all stages from the compressor 20 to the surrounding environment can be enhanced.
[0116] Optionally, the heat conduction element 310 includes a connecting pipe assembly 311, which is connected to the heat dissipation element 320 and the heat absorption part 200, and the space inside the connecting pipe assembly 311 is part of the filling space.
[0117] When the heat transfer element 310 includes the connecting pipe assembly 311, the placement of the heat absorption part 200 and the heat dissipation part 320 is less restricted. Since the space inside the connecting pipe assembly 311 is part of the charging space, the heat transfer efficiency from the compressor 20 to the environment where the compressor 20 is located is high. When the heat transfer element 310 includes the connecting pipe assembly 311, it is advantageous to place the conductive part 150.
[0118] Optionally, combined Figure 9 As shown, the heat-conducting element also includes a conductive component 150, which is disposed on the connecting pipe assembly 311.
[0119] As another way to enable the heat-conducting element to start at a temperature greater than or equal to a first preset temperature, the heat-conducting element is started or stopped by opening and closing the conductive component 150. Specifically, the heat-conducting element includes a heat dissipation body 100, which is configured with a refrigerant flow channel 140, and the refrigerant flow channel 140 is provided with the conductive component 150. When the conductive component 150 is open, the refrigerant flow can form a flow path, thereby dissipating heat to the compressor 20 through the gas-liquid two-phase change of the refrigerant. When the conductive component 150 is closed, the refrigerant cannot flow in the refrigerant flow channel 140, and the heat-conducting element does not dissipate heat to the compressor 20.
[0120] This configuration places lower requirements on the refrigerant charging ratio and pressure of the heat-conducting elements. Adding the conductive component 150 reduces the process requirements for charging the refrigerant to the heat-conducting elements, improving the consistency among multiple elements. Furthermore, in cases where the heat-conducting elements can self-start based on charging pressure and the refrigerant's inherent properties, adding the conductive component 150 provides a safety mechanism, reducing or preventing accidental activation of the heat-conducting elements.
[0121] Optionally, the refrigerant flow path 140 includes an annular loop, and the connecting component 150 is disposed in the annular loop.
[0122] For example, the refrigerant flow channel 140 with gradual heat dissipation is in the form of the aforementioned pulsating heat pipe, and the conductive component 150 is disposed at one position of the pulsating heat pipe. This arrangement facilitates the control of the start and stop of the heat-conducting element by the conductive component 150.
[0123] Optionally, the first end of the refrigerant flow channel 140 is provided with a first interface, and the second end of the refrigerant flow channel 140 is provided with a second interface.
[0124] In this configuration, the conductive component 150 is disposed in the refrigerant channel 140. The refrigerant channel 140 has a first interface and a second interface, through which it can be connected to the refrigerant circulation system. For example, the first interface of the refrigerant channel 140 is connected to the inlet of the evaporator, and the second interface is connected to the outlet of the evaporator. Thus, the refrigerant channel 140 and the evaporator are connected in parallel. A portion of the liquid refrigerant in the refrigerant circulation system enters the refrigerant channel 140 through the first interface, evaporates and absorbs heat near the compressor, and then exits the refrigerant channel 140 through the second interface. In this configuration, since the compressor is cooled by liquid refrigerant, the heat dissipation efficiency of the compressor is higher.
[0125] Optionally, the heat-conducting element further includes heat dissipation fins, which are disposed on the heat absorption section 200 and / or the heat dissipation section 300.
[0126] The heat-absorbing part 200 is attached to the outer wall of the compressor 20 and is equipped with heat dissipation fins, which effectively increases the heat dissipation area of the compressor 20 casing. Because of the significant temperature difference between the compressor 20 and its surrounding environment, the heat dissipation fins also have a relatively significant heat dissipation effect. This arrangement increases the heat dissipation capacity of the heat-conducting elements.
[0127] This disclosure provides a heat dissipation assembly 10 for a compressor 20. The heat dissipation assembly 10 includes the aforementioned heat-conducting element and an auxiliary device. The auxiliary device is configured to activate when the temperature is greater than or equal to a second temperature to increase the heat dissipation rate of the heat dissipation element 620.
[0128] Using the heat dissipation component 10 provided in this embodiment, the heat-conducting element does not dissipate heat from the compressor 20 during the initial startup phase, allowing the compressor 20 to quickly reach its optimal operating temperature range. When the air conditioner is running in cooling mode, the heat-conducting element allows the compressor 20 to operate in near-isothermal compression mode after it has stabilized, improving the air conditioner's high-temperature cooling capacity. When the air conditioner is running in heating mode, the heat-conducting element does not activate, and the heat generated by the compressor 20 compressing the refrigerant is not dissipated into the environment surrounding the compressor 20, thus improving the compressor 20's heating capacity.
[0129] Optionally, if the startup temperature of the heat dissipation element 620 is the first temperature, the second temperature is greater than or equal to the first temperature.
[0130] The auxiliary device can enhance the heat dissipation effect of the heat-conducting element. When the auxiliary device is activated, the heat dissipation rate of the heat dissipation assembly 10 is increased. During the operation of the compressor 20, the heat dissipation demand of the compressor 20 varies. When the heat dissipation demand of the compressor 20 is low, the compressor 20 is cooled solely by the self-starting heat-conducting element. When the heat dissipation demand of the compressor 20 is high, the compressor 20 is cooled jointly by the heat-conducting element and the auxiliary device. This allows the heat dissipation demand of the compressor 20 to be matched with the heat dissipation capacity of the heat dissipation assembly 10, thereby making the compressor 20 operate closer to isothermal compression.
[0131] Optionally, combined Figure 10 As shown, the heat-conducting element includes a heat dissipation body 100 and an auxiliary device including a water pump 161. The heat dissipation body 100 is adapted to make heat transfer contact with the compressor 20. The heat dissipation body 100 is constructed with a water-cooled flow channel 160. The water pump 161 is connected to the water-cooled flow channel 160. The water pump 161 is started when the temperature of the compressor 20 is greater than or equal to a first preset temperature to drive water to flow in the water-cooled flow channel 160.
[0132] As another way to enable the heat dissipation component 10 to start at a temperature greater than or equal to a first preset temperature, the heat dissipation component 10 is water-cooled. Specifically, the heat dissipation body 100 is constructed with a water-cooling channel 160, and a water pump 161 is provided on the heat dissipation body 100 corresponding to the water-cooling channel 160. When the water pump 161 is running, it drives cooling water to flow through the water-cooling channel 160, thereby reducing the temperature of the compressor 20. When the water pump 161 stops running, the heat dissipation component 10 does not dissipate heat from the compressor 20.
[0133] Using water cooling provides better heat dissipation for compressor 20.
[0134] Optionally, the heat dissipation component 10 is also configured with a water storage space 162, which is connected to the water cooling channel 160 to form a water circulation loop.
[0135] The water storage space 162 of the heat dissipation assembly 10 can store some water. For example, the heat dissipation assembly 10 includes a water tank with the water storage space 162. Since the water storage space 162 and the water-cooling channel 160 form a water circulation loop, the overall heat dissipation of the compressor 20 is positively correlated with the amount of water stored in the water tank. This increases the heat dissipation capacity of the heat dissipation assembly 10 for the compressor 20.
[0136] Optionally, combined Figure 11 As shown, the heat-conducting element includes a heat dissipation body 100 and an auxiliary device including a cooling fan 163. The heat dissipation body 100 is adapted to make heat transfer contact with the compressor 20. The cooling fan 163 is set corresponding to the heat dissipation body 100 and is turned on when the temperature is greater than or equal to a first preset temperature to drive airflow through the heat dissipation body 100.
[0137] As another way to enable the heat dissipation component 10 to start at a temperature greater than or equal to a first preset temperature, the heat dissipation component 10 includes a heat dissipation body 100 and a cooling fan 163. When the cooling fan 163 is running, the heat dissipation component 10 starts and removes heat from the compressor 20. When the cooling fan 163 stops running, the heat dissipation component 10 shuts down, and the temperature of the heat dissipation component 10 tends to be the same as the temperature of the compressor 20.
[0138] The cooling fan 163 is installed so that the air in the environment where the compressor 20 is located can carry away the heat generated by the compressor 20, and the cooling of the compressor 20 can be carried out continuously.
[0139] Optionally, combined Figure 12 As shown, the heat-conducting element includes a heat dissipation body 100, and the auxiliary device includes a damper assembly 164. The heat dissipation body 100 is adapted to make heat transfer contact with the compressor 20. The damper assembly 164 opens to divert a portion of the air to the heat dissipation body 100 when the temperature is greater than or equal to a first preset temperature.
[0140] As another way to enable the heat dissipation assembly 10 to start at a temperature greater than or equal to a first preset temperature, the heat dissipation assembly 10 includes a heat dissipation body 100 and a damper assembly 164. When the damper assembly 164 is open, it allows air to flow through the heat dissipation body 100 and carries away the heat emitted by the compressor 20, which is in heat transfer contact with the heat dissipation body 100. With this configuration, there is no need to install a cooling fan 163, which helps to reduce the energy consumption of the air conditioner in cooling the compressor 20.
[0141] It should be noted that the heat dissipation body 100 is constructed with a refrigerant charging space, a water-cooled flow channel 160, and a corresponding cooling fan 163 or damper assembly 164. These heat dissipation control methods can be combined. By combining them, the compressor 20 can achieve a better heat dissipation effect. For example, when the heat dissipation demand is low, the compressor 20 is heated only by the gas-liquid two-phase change in the refrigerant charging space; when the heat dissipation demand is high, the water pump 161 or cooling fan 163 is started, or the damper assembly 164 is opened. This allows the heat dissipation capacity of the heat dissipation assembly 10 to match the heat dissipation demand of the compressor 20, thereby enabling the compressor 20 to operate in a manner closer to isothermal compression.
[0142] This disclosure provides a compressor assembly, which includes a compressor and the aforementioned heat-conducting element or the aforementioned heat dissipation assembly 10.
[0143] Using the compressor assembly provided in this embodiment, the heat-conducting element does not dissipate heat from the compressor 20 during the initial startup phase, allowing the compressor 20 to quickly reach its optimal operating temperature range. When the air conditioner is running in cooling mode, the heat-conducting element allows the compressor 20 to operate in near-isothermal compression mode after it has stabilized, improving the air conditioner's high-temperature cooling capacity. When the air conditioner is running in heating mode, the heat-conducting element does not activate, and the heat generated by the compressor 20 compressing the refrigerant is not dissipated into the environment surrounding the compressor 20, thus improving the compressor 20's heating capacity.
[0144] Optionally, the compressor assembly also includes a temperature sensor and a control device, wherein the temperature sensor is used to obtain the exhaust temperature of the compressor 20, and the control device is configured to activate the heat dissipation assembly 10 to dissipate heat from the compressor 20 when the temperature of the compressor 20 is greater than or equal to a first preset temperature.
[0145] The compressor assembly is equipped with a temperature sensor and a control device. The control device of the compressor assembly can control the start and stop of the heat dissipation component 10 according to the temperature of the temperature sensor, which is beneficial for the compressor assembly to automatically make the compressor 20 run isothermal compression.
[0146] Optionally, when the heat-conducting element includes a heat-absorbing part 200 and a heat-dissipating part 300, the heat-absorbing part 200 makes heat transfer contact with the compressor to reduce the temperature of the compressor 20.
[0147] This configuration reduces heat buildup inside the compressor 20, which facilitates more precise thermal management of the compressor 20 through the heat dissipation component 10.
[0148] Alternatively, the heat-absorbing part 200 is configured to conform to the shape of the outer wall of the compressor 20.
[0149] The refrigerant rises sequentially from the suction end, compression cylinder, and discharge end of the compressor 20. The high-temperature refrigerant discharged from the compressor casing comes into contact with the compressor cylinder, which also facilitates heat transfer. The shape of the heat-absorbing portion 200 of the heat dissipation assembly 10 is adapted to the shape of the outer wall of the compressor 20, allowing for better heat absorption when assembled into the compressor 20.
[0150] Optionally, the heat absorption section 200 is disposed within the compressor 20.
[0151] With the heat-absorbing part 200 located inside the compressor 20, it can more fully contact the high-temperature refrigerant in the compressor 20. Due to the heat convection between the gaseous refrigerant and the heat-absorbing part 200, the heat generated by the compressor 20 compressing the refrigerant can be more fully transferred to the heat-absorbing part 200 of the heat dissipation assembly 10. The heat dissipation part 300 is located outside the compressor 20 and is heat-transferringly connected to the heat-absorbing part 200. For example, the compressor housing has a connection hole, and the heat dissipation assembly 10 includes a connecting pipe that passes through the connection hole and is connected at both ends to the heat-absorbing part 200 and the heat dissipation part 300, respectively.
[0152] This configuration can further improve the heat dissipation effect of the heat dissipation component 10 on the compressor 20.
[0153] Optionally, the heat absorption section 200 is disposed inside the compressor 20 and located between the compression cylinder and the exhaust port of the compressor 20.
[0154] The heat absorption section 200 is located between the compression cylinder and the exhaust port of the compressor 20, that is, at the position with the highest temperature in the compressor 20. This increases the temperature difference between the refrigerant in the compressor 20 and the heat absorption section 200, thereby improving the heat dissipation effect of the heat dissipation assembly 10.
[0155] Optionally, the heat-absorbing part 200 includes a heat contact plate having an arcuate surface adapted to conform to the outer wall of the compressor 20.
[0156] With this configuration, the assembly of the heat absorption unit 200 and the compressor 20 is relatively convenient.
[0157] Optionally, the heat absorption section 200 includes a heat absorption cylinder 220, which is sleeved on the compressor 20 and has its inward side adapted to abut against the outer wall of the compressor 20.
[0158] This arrangement increases the contact area between the heat-absorbing part 200 and the compressor 20, thereby enhancing the heat absorption effect of the heat-absorbing part 200. Furthermore, this arrangement facilitates the installation and securing of the heat-absorbing part 200.
[0159] Optionally, the heat contact plate or heat absorption cylinder 220 is provided with multiple heat dissipation fins extending radially outward.
[0160] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides an outdoor air conditioning unit, which includes a housing 410, a partition 420, an outdoor fan 430, and the aforementioned compressor assembly. The housing 410 has an accommodating space; the partition 420 is disposed in the accommodating space to divide the accommodating space into a heat exchanger compartment and a compressor compartment. The heat exchanger compartment has an air inlet and an air outlet. The outdoor fan 430 is disposed in the heat exchanger compartment and is used to drive air to flow from the air inlet to the air outlet; the aforementioned compressor assembly is installed in the accommodating space, and the compressor of the compressor assembly is disposed in the compressor compartment.
[0161] In this embodiment, the outdoor unit of the air conditioner includes a compressor compartment and a heat exchanger compartment. The heat exchanger and outdoor fan 430 of the outdoor unit are disposed in the heat exchanger compartment, and the outdoor fan 430 drives air to flow through the outdoor heat exchanger when it is running. The compressor assembly is disposed in the compressor compartment. The compressor assembly includes a compressor 20 and a heat dissipation device, which is activated when the temperature of the compressor 20 is greater than or equal to a first preset temperature to enable the compressor 20 to perform isothermal compression.
[0162] Using the outdoor unit of the air conditioner provided in this embodiment, the heat dissipation component 10 does not dissipate heat from the compressor 20 during the initial startup phase, allowing the compressor 20 to quickly reach its optimal operating temperature range. When the air conditioner is running in cooling mode, the heat dissipation component 10 allows the compressor 20 to operate in near-isothermal compression mode after it has stabilized, improving the air conditioner's high-temperature cooling capacity. When the air conditioner is running in heating mode, the heat dissipation component 10 does not start, and the heat generated by the compressor 20 compressing the refrigerant is not dissipated into the environment surrounding the compressor 20, thus improving the compressor 20's heating capacity.
[0163] Optionally, when the heat dissipation assembly 10 includes a damper assembly 164, the damper assembly 164 is disposed on the partition 420, and when the damper assembly 164 is opened, the outdoor fan 430 drives a portion of the air to flow through the heat dissipation assembly 10.
[0164] The damper assembly 164 is positioned on the partition 420, which allows for better airflow through the heat dissipation assembly 10. With this configuration, air cooling of the heat dissipation assembly 10 can be achieved without the need for an additional fan, allowing the outdoor unit of the air conditioner to achieve thermal management of the compressor 20 at a lower cost.
[0165] Optionally, when the heat dissipation assembly 10 includes a cooling fan 163, the compressor compartment is provided with an auxiliary air inlet and an auxiliary air outlet. When the cooling fan 163 is running, it drives air to flow from the auxiliary air inlet through the compressor 20 to the auxiliary air outlet.
[0166] The compressor compartment has separate auxiliary air inlets and outlets, ensuring that the air driven by the cooling fan 163 is not affected by the high-temperature outdoor heat exchanger. Due to the lower air temperature, the temperature difference between the air and the heat dissipation assembly 10 is significant, thus improving the heat dissipation effect of the heat dissipation assembly 10 on the compressor 20.
[0167] Optionally, when the heat-conducting element includes a heat-absorbing part 200 and a heat-dissipating part 300, the partition 420 is provided with an installation window, and the heat-dissipating part 300 is mounted in the installation window and is at least partially exposed to the heat exchanger compartment.
[0168] Because the heat dissipation unit 300 is installed in the mounting window of the partition 420, the heat absorbed by the heat absorption unit 200 is dissipated in the heat exchanger compartment by the heat dissipation unit 300. When the outdoor fan 430 of the heat exchanger compartment is running, it drives a large amount of air to flow through the outdoor heat exchanger and the heat dissipation unit 300, making the heat dissipation capacity of the air conditioner outdoor unit for the compressor 20 stronger.
[0169] Optionally, the heat dissipation unit 300 is inclined from the air inlet to the air outlet in a direction close to the outdoor fan 430.
[0170] In this configuration, a portion of the air flowing through the heat exchanger compartment is blown towards the heat dissipation section 300 in a generally oriented direction. This increases the heat exchange efficiency between the air and the heat dissipation section 300. Because the heat dissipation section 300 is inclined, the airflow velocity decreases less as it flows through it, thus mitigating the reduction in airflow volume when the outdoor unit dissipates heat from the heat dissipation assembly 10, and consequently reducing the heat exchange between the air and the outdoor heat exchanger during this process. This arrangement improves the heat dissipation effect of the outdoor unit on the compressor 20 and reduces the cooling impact of the outdoor unit on the outdoor heat exchanger.
[0171] Optionally, the partition 420 includes a first sheet metal part 421 and a second sheet metal part 422, wherein the first sheet metal part 421 is vertically disposed in the accommodating space and extends along the thickness direction of the housing 410; the second sheet metal part 422 is vertically disposed in the accommodating space and extends along the length direction of the housing 410, and the first sheet metal part 421 and the second sheet metal part 422 are connected; wherein the mounting window is partially opened in the first sheet metal part 421 and partially opened in the second sheet metal part 422.
[0172] When the outdoor unit of the air conditioner is in use, the partition 420 is L-shaped when viewed from above. The mounting window is located on the first sheet metal part 421 and partially opened on the second sheet metal part 422. This facilitates the fixing of the heat dissipation part 300 and keeps the outdoor heat exchanger in an inclined position.
[0173] Optionally, the first side of the air inlet near the compressor compartment is offset from the first side of the air outlet near the compressor compartment, and the heat dissipation part 300 is located between the first side of the air inlet and the first side of the air outlet on the projection of the plane where the air outlet is located.
[0174] With this configuration, the outdoor unit of the air conditioner has a more aesthetically pleasing appearance, and more air can flow through the heat dissipation section 300 of the heat dissipation component 10.
[0175] Optionally, the outdoor unit of the air conditioner also includes an electrical control box 610, a circuit board, and a heat dissipation element 620. The electrical control box 610 is located on the partition 420, with part of the electrical control box 610 located in the compressor compartment and part in the heat exchanger compartment. The circuit board is located inside the electrical control box 610. The heat dissipation element 620 is thermally connected to the circuit board and is located in the heat exchanger compartment. When the outdoor fan 430 is running, it also drives air to flow through the heat dissipation element 620.
[0176] When an air conditioner is cooling in a high-temperature environment, if the circuit board temperature is high, it will trigger the circuit board's high-temperature protection. The electrical control box 610 is located on the partition 420 and partly in the heat exchanger compartment. When the outdoor fan 430 is running, it can drive airflow through the heat dissipation element 620, thereby reducing the temperature of the circuit board. This arrangement allows for control of the circuit board temperature, reducing or preventing the air conditioner from shutting down due to high circuit board temperature, and improving the air conditioner's high-temperature cooling capacity.
