[0002] There are generally high-pressure and high-temperature chambers and low-pressure and low-temperature chambers inside the compressor shell. A partition is provided between the high-pressure chamber and the low-pressure chamber. The high-temperature shell will be transferred to the low-temperature chamber through the partition. When the temperature in the high-pressure and high-temperature chamber is high, the temperature gradient between the chambers is large, and the temperature transferred from the high-pressure and high-temperature side shell to the low-temperature chamber will be higher. The excessively high temperature on the high-pressure side of the compressor will be transferred to the suction side of the low-pressure shell through the partition, resulting in an increase in the refrigerant suction temperature, a larger vapor specific volume, a decrease in suction efficiency, and a low compressor suction volume rate. At the same time, overheated gas will cause power consumption to increase. The present invention is used to solve the technical problem in the prior art that the suction air is heated and the temperature rises, resulting in a low compressor suction volume rate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Reference below Figure 1-Figure 7A compressor 100 according to an embodiment of the present invention is described.

[0045] like Figure 1 As shown, the compressor 100 according to the embodiment of the present invention includes a high-pressure shell 101 , a low-pressure shell 102 , a partition 103 , a compression mechanism 20 , a crankshaft 320 , and a driving component 310 .

[0046] The high-pressure shell 101 is provided with a first opening (not shown in the figure), and the high-pressure shell 101 is provided with an exhaust port 101c. The low-pressure shell 102 has a second opening 102a. The partition 103 is provided between the high-pressure shell 101 and the low-pressure shell 102 to block the first opening and the second opening 102a. The partition 103 is provided with an intake passage 103a connected to the intake port. The thermal conductivity of the material of the partition 103 is less than the thermal conductivity of the material of the high-pressure shell 101 and / or the thermal conductivity of the material of the partition 103 is less than the thermal conductivity of the material of the low-pressure shell 102. The compression mechanism 20 is provided in the high-pressure shell 101, and the compression mechanism 20 has a compression chamber, which is used to compress the refrigerant flowing out of the intake passage 103a, and the compression chamber is connected to the exhaust port 101c. The crankshaft 320 passes through the partition 103 and cooperates with the piston of the compression mechanism 20, and the driving component 310 is provided in the low-pressure shell 102 and connected to the crankshaft 320.

[0047] When the compressor 100 is working, the driving component 310 can drive the crankshaft 320 to move, and then the crankshaft 320 drives the piston of the compression mechanism part 20 to work, so that the refrigerant can enter the intake channel 103a from the air inlet port, and then the refrigerant enters the air intake port of the compression mechanism part 20 from the air inlet channel 103a. The volume change of the refrigerant is compressed by the compression chamber, so that the refrigerant becomes a high-pressure and high-temperature gas, and then is discharged from the exhaust port 101c.

[0048] Since the refrigerant in the high-pressure shell 101 is generally a high-pressure and high-temperature gas, the high temperature will be transferred to the low-temperature and low-pressure low-pressure shell 102. Since the thermal conductivity of the material of the partition 103 is relatively small, it can reduce the heat transfer and make the temperature rise of the low-pressure shell 102 not obvious or relatively small.

[0049] Among them, the thermal conductivity of the material of the partition 103 can be smaller than the thermal conductivity of the material of the high-pressure shell 101, or the thermal conductivity of the material of the partition 103 is smaller than the thermal conductivity of the material of the low-pressure shell 102, or the thermal conductivity of the material of the partition 103 is smaller than both the thermal conductivity of the material of the high-pressure shell 101 and the thermal conductivity of the material of the low-pressure shell 102.

[0050] According to the compressor 100 of the embodiment of the present invention, the thermal conductivity of the material of the partition 103 is smaller than the thermal conductivity of the material of the high-pressure shell 101 and / or the thermal conductivity of the material of the partition 103 is smaller than the thermal conductivity of the material of the low-pressure shell 102. This can effectively reduce the high temperature of the high-pressure shell 101 from being transferred to the low-pressure shell 102, avoid the refrigerant temperature in the intake chamber being heated by the high-temperature gas, thereby reducing the loss of intake volumetric efficiency caused by thermal expansion of the intake air, and avoiding the efficiency drop caused by intake heating, which is beneficial to improving the isentropic efficiency of the compressor 100.

[0051] In some embodiments, the thermal conductivity of the material of the partition 103 is λ1, and the thermal conductivity of the material of the high-pressure shell 101 and the low-pressure shell 102 with the smallest thermal conductivity is λ2, wherein λ1≤1 / 3λ2.

[0052] The thermal conductivity of the materials of the high-pressure shell 101 and the low-pressure shell 102 may be equal or unequal. The smallest thermal conductivity of the materials of the high-pressure shell 101 and the low-pressure shell 102 may be called λ2. As long as the thermal conductivity λ1 of the material of the partition 103 is less than λ2, the heat transfer between the high-pressure shell 101 and the low-pressure shell 102 can be effectively blocked.

[0053] The relationship between λ1 and λ2 may satisfy: λ1≤1 / 3λ2. Within this range, the cooling capacity, power consumption and refrigerant flow rate of the compressor 100 may be significantly improved.

[0054] like Figure 4 As shown in the figure, the horizontal axis is the partitions of different material thermal conductivities, wherein the values ​​of λ4, λ3, and λ1 decrease successively, λ4 and λ3 can be understood as the material thermal conductivities of traditional partitions, and the vertical axis is the cooling capacity of the compressor 100. It can be seen that the cooling capacity of the compressor 100 of the present invention is significantly improved.

[0055] like Figure 5 As shown in the figure, the horizontal axis is the partitions of different material thermal conductivities, wherein the values ​​of λ4, λ3, and λ1 decrease successively, λ4 and λ3 can be understood as the material thermal conductivities of traditional partitions, and the vertical axis is the power consumption of the compressor 100. It can be seen that the power consumption of the compressor 100 of the present invention is significantly reduced.

[0056] like Figure 6 As shown in the figure, the horizontal axis represents partitions of different material thermal conductivities, wherein the values ​​of λ4, λ3, and λ1 decrease successively, λ4 and λ3 can be understood as the material thermal conductivities of traditional partitions, and the vertical axis represents the refrigerant flow rate of the compressor 100. It can be seen that the refrigerant flow rate of the compressor 100 of the present invention is significantly improved.

[0057] In some embodiments, 1 / 20λ2≤λ1≤1 / 3λ2. Figure 7 As shown, Figure 7The horizontal axis is the thermal conductivity of the partition 103, and the vertical axis is the energy efficiency improvement rate of the refrigerant flow of the compressor 100. Figure 7 It can be seen that as the value of λ1 gradually decreases, the energy efficiency of the refrigerant flow of the compressor 100 gradually improves, and when λ1≤1 / 3λ2, the energy efficiency of the refrigerant flow is improved by more than 3.0%, and the improvement effect is more obvious. When λ1≤1 / 20λ2, after the energy efficiency of the refrigerant flow is improved by 8%, the improvement is almost not obvious. Therefore, λ1 is set to satisfy: 1 / 20λ2≤λ1≤1 / 3λ2, which can not only take into account the energy efficiency improvement effect of the refrigerant flow, but also help to reduce the material cost of the partition 103, taking into account the economy.

[0058] For example, λ1 may be 1 / 20λ2, 1 / 15λ2, 1 / 10λ2, 1 / 8λ2, 1 / 6λ2, 1 / 4λ2, 1 / 3λ2, and so on.

[0059] In some embodiments, λ1≤1 / 3λ2≤90W / (m·K). That is, the partition 103 may be made of a material with relatively low thermal conductivity, specifically less than or equal to 90W / (m·K). For example, λ1 may be 90W / (m·K), 88W / (m·K), 84W / (m·K), 80W / (m·K), 75W / (m·K), 70W / (m·K), 65W / (m·K), etc.

[0060] In some embodiments, the high-pressure shell 101 is an aluminum alloy part, the low-pressure shell 102 is an aluminum alloy part, and the partition 103 is a gray iron part or a stainless steel part. That is to say, the thermal conductivity of the gray iron part is less than one-third of the thermal conductivity of the aluminum alloy part, and the thermal conductivity of the stainless steel part is also less than one-third of the thermal conductivity of the aluminum alloy part. By setting the partition 103 to be a gray iron part or a stainless steel part, the high-pressure shell 101 is an aluminum alloy part, and the low-pressure shell 102 is an aluminum alloy part, the thermal conductivity of the partition 103 and the high-pressure shell 101 is relatively different, and the thermal conductivity of the partition 103 and the low-pressure shell 102 is relatively different, which is conducive to reducing the heat transfer between the high-pressure shell 101 and the low-pressure shell 102.

[0061] In some embodiments, Figure 2 As shown, the high-pressure housing 101 has a first end 1011, a first positioning groove 1011a is provided on the first end 1011, the partition 103 stops at the first end 1011, a first positioning convex portion 1032 is provided on the partition 103, and the first positioning convex portion 1032 is arranged in the first positioning groove 1011a. The first positioning convex portion 1032 cooperates with the first positioning groove 1011a to facilitate the installation and positioning of the partition 103 on the high-pressure housing 101, thereby improving assembly efficiency and installation reliability.

[0062] In some embodiments, Figure 2 As shown, the low-pressure housing 102 has a second end 1021, a second positioning groove 1021a is provided on the second end 1021, the partition 103 stops at the second end 1021, a second positioning convex portion 1033 is provided on the partition 103, and the second positioning convex portion 1033 is arranged in the second positioning groove 1021a. The cooperation between the second positioning convex portion 1033 and the second positioning groove 1021a is conducive to achieving the installation and positioning of the partition 103 on the low-pressure housing 102, thereby improving the assembly efficiency and installation reliability.

[0063] In some embodiments, such as Figure 1 As shown, the low-pressure housing 102 is provided with an air inlet (not shown in the figure). In this way, since the air intake temperature of the air inlet is relatively low, the air inlet is provided on the low-pressure housing 102 to cool the driving component 310.

[0064] In some embodiments, such as Figure 1 As shown, a receiving groove 1031a is provided on one side of the partition 103 facing the compression mechanism part 20, and the receiving groove 1031a is communicated with the exhaust port 101c. The compression mechanism part 20 is provided with a first muffler 70 located in the receiving groove 1031a, and the first muffler 70 is provided with a first vent (not shown) communicated with the receiving groove 1031a, and the first muffler 70 is communicated with the exhaust valve port. The first muffler 70 can play a role in silencing and reducing noise, and the receiving groove 1031a can provide the installation space required for the first muffler 70, so that the structural layout between the partition 103 and the compression mechanism part 20 is more compact, which is conducive to saving space.

[0065] In some embodiments, such as Figure 1 As shown, a first exhaust passage 101a communicating with the exhaust port 101c is provided in the high-pressure housing 101, and a second exhaust passage 1032a communicating with the accommodating groove 1031a and the first exhaust passage 101a is provided on the partition 103. That is, by forming the second exhaust passage 1032a on the partition 103, pipe parts can be saved, and the passage is set by utilizing the structure of the partition 103 itself, which can save space and make the structural layout between the partition 103 and the compression mechanism 20 more compact.

[0066] Optionally, the first exhaust passage 101a is disposed in the side wall portion of the high-pressure housing 101. In this manner, there is no need to provide a separate pipe component to serve as the first exhaust passage 101a, which can save materials. Secondly, the first exhaust passage 101a is disposed in the side wall portion of the high-pressure housing 101, which is also conducive to saving the internal space of the high-pressure housing 101, making the internal structure of the high-pressure housing 101 more compact, which is conducive to reducing the overall volume.

[0067] In some embodiments, such as Figure 1As shown, the second exhaust channel 1032a is an oblique channel extending obliquely. The oblique channel can make the channel between the receiving groove 1031a and the first exhaust channel 101a shorter, reducing the refrigerant flow path, and the channel formed by the oblique channel is a straight channel, which can reduce the probability of corners and improve the smoothness of refrigerant exhaust.

[0068] In some embodiments, Figure 2 As shown, a first mounting hole 101b is provided on the high-pressure shell 101, a second mounting hole 102b is provided on the low-pressure shell 102, a third mounting hole 103b is provided on the partition 103, and the compressor 100 also includes a fastener 104, which is passed through the first mounting hole 101b, the second mounting hole 102b and the third mounting hole 103b.

[0069] That is, the fastener 104 is inserted into the first mounting hole 101b, the second mounting hole 102b and the third mounting hole 103b, thereby realizing the connection between the high-pressure housing 101, the partition 103 and the low-pressure housing 102. This connection method is relatively simple and reliable.

[0070] For example, the fastener 104 may be a connecting pin, and the first mounting hole 101b, the second mounting hole 102b, and the third mounting hole 103b may be a plain hole. For another example, the fastener 104 is a bolt, and at least one of the first mounting hole 101b, the second mounting hole 102b, and the third mounting hole 103b may be a screw hole.

[0071] In some embodiments, the high-pressure housing 101, the partition 103 and the low-pressure housing 102 are connected by welding. The welding connection is reliable, and the high-pressure housing 101, the partition 103 and the low-pressure housing 102 are not easy to loosen.

[0072] In some embodiments, Figure 1 As shown, the compressor 100 also includes an end cover 40, which is fixed to the end of the low-pressure shell 102 facing away from the high-pressure shell 101, and a receiving cavity for placing an electronic control element is defined between the end cover 40 and the low-pressure shell 102, and the electronic control element is electrically connected to the driving component 310.

[0073] Since the driving component 310 is arranged in the low-pressure housing 102, the driving component 310 is prone to vibration when working. By arranging the end cover 40 at the end of the low-pressure housing 102 away from the high-pressure housing 101, and arranging the electric control element in the accommodating cavity defined between the end cover 40 and the low-pressure housing 102, it is beneficial to balance the weight on both sides of the driving component 310 and reduce the vibration generated when the driving component 310 is working. Secondly, the accommodating cavity formed between the end cover 40 and the low-pressure housing 102 can also play a role in protecting the electric control element, preventing the electric control element from being exposed to the outside and causing damage.

[0074] In some embodiments, Figure 1 As shown, a through hole 103c is provided on the partition plate 103, and the crankshaft 320 is passed through the through hole 103c. The driving component 310 may be a stator-rotor assembly.

[0075] In some embodiments, Figure 1 As shown, the compression mechanism 20 includes a first bearing 201, a first cylinder 202, a partition 203, a second cylinder 204 and a second bearing 205 which are sequentially arranged along the axial direction of the high-pressure shell 101. The compression mechanism 20 also includes a first piston 206 and a second piston 207. The first piston 206 is arranged in the first cylinder 202, and the second piston 207 is arranged in the second cylinder 204. The first piston 206 and the second piston 207 define a compression chamber. The crankshaft 320 drives the first piston 206 to rotate relative to the second piston 207. The compressor 100 also includes a first threaded fastener 50 and a second threaded fastener 60. The first threaded fastener 50 is penetrated through the partition 103 and the first bearing 201, and the second threaded fastener 60 is penetrated through the first bearing 201, the first cylinder 202, the partition 203, the second cylinder 204 and the second bearing 205.

[0076] In the above scheme, the partition 203 plays a role in reducing heat transfer between the first cylinder 202 and the second cylinder 204. Its role can be referred to the partition 103, and will not be repeated here. Among them, the first bearing 201 is fixed to the partition 103 by the first threaded fastener 50, and the first bearing 201, the first cylinder 202, the partition 203, the second cylinder 204 and the second bearing 205 are fixed to the first bearing 201 by the second threaded fastener 60, so that the compression mechanism 20 is fixed to the high-pressure shell 101 and the low-pressure shell 102.

[0077] Alternatively, the first threaded fastener 50 and the second threaded fastener 60 may be bolts or studs.

[0078] In some embodiments, Figure 1 As shown, a second silencer 80 is disposed on the second bearing 205 , and the second silencer 80 plays a role in silencing and reducing noise, thereby further reducing the noise generated when the compression mechanism 20 is working.

[0079] The air conditioning system 1 according to the embodiment of the present invention includes the compressor 100 mentioned above.

[0080] like Figure 3As shown, the vehicle 1000 according to an embodiment of the present invention includes the air conditioning system 1 mentioned above. Here, the vehicle 1000 can be a new energy vehicle. In some embodiments, the new energy vehicle can be a pure electric vehicle with a motor as the main driving force. In other embodiments, the new energy vehicle can also be a hybrid vehicle with an internal combustion engine and a motor as the main driving force. Regarding the internal combustion engine and the motor mentioned in the above embodiments that provide driving power for the new energy vehicle, wherein the internal combustion engine can use gasoline, diesel, hydrogen, etc. as fuel, and the method of providing electrical energy to the motor can use a power battery, a hydrogen fuel cell, etc., which is not specifically limited here. It should be noted that this is only an exemplary description of the structure of new energy vehicles, etc., and it does not limit the scope of protection of the present invention / invention.

[0081] Furthermore, in some embodiments, the compressor 100 applicable to the above-mentioned new energy vehicles according to the embodiments of the present invention may be an electric compressor including a driving part and a compression part, the driving part may refer to the stator-rotor assembly 30 mentioned above, and the compression part may refer to the compression mechanism part 20, and the driving part in the electric compressor drives the compression part to perform compression work, for example, the driving part may be a driving motor including a rotor and a stator. In addition, in some embodiments, the electric compressor may be a low back-pressure compressor, the driving part may be arranged in a low-pressure chamber connected to the air intake port of the compressor, and the compression part may be arranged in a high-pressure chamber connected to the air exhaust port of the compressor. In addition, in some embodiments, the electric compressor may be a horizontal compressor, the driving part and the compression part may be arranged in a horizontal direction, and so on.
