Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle air conditioners, and particularly relates to a vehicle energy-saving air conditioner and a motor module for an air conditioner. Background Art

[0002] With the continuous depletion of energy, new energy vehicles have become the focus of research. As a new energy vehicle, electric vehicles are currently the easiest to mass-produce and have received widespread attention. As one of the core technologies of electric vehicles, drive motors have always been the focus of research in the industry. Currently, most drive motors are permanent magnet synchronous motors with a single output shaft, which are installed at the bottom of electric vehicles to provide power for the vehicles.

[0003] In the prior art, the method of liquid cooling for an outer rotor motor is to set a cooling cavity inside the motor stator. The principle of this cooling method is that the heat on the iron core transfers the heat to the stator through heat conduction, and then the coolant in the stator cooling cavity cools the stator, thereby taking away the heat generated by the motor. Most motors commonly used in the market are equipped with a fan structure and output the heat to the external air.

[0004] However, in actual use, the cooling method of setting a cooling cavity inside the motor stator belongs to indirectly cooling the iron core. The setting of this cooling structure cannot achieve direct contact cooling of the stator iron core and the entire motor module. Moreover, although the fan structure can well solve the heat dissipation problem of the motor, due to the large noise of the fan, a noise eliminator needs to be installed to reduce the impact of the noise.

[0005] Therefore, we propose a vehicle energy-saving air conditioner and a motor module for an air conditioner to solve the problem that the existing cooling structure cannot efficiently cool and lower the temperature of the stator iron core and the entire motor module, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption during the operation of the motor module.

[0036] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clear and understandable, the following further elaborates on the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figure 1-16, the present invention provides a technical solution: a vehicle energy-saving air conditioner, including a compressor body 1, a refrigerant pipeline 2, a condenser 3, a liquid receiver dryer 4, a thermostatic expansion valve 6 and an evaporator 7. The output end of the compressor body 1 is hermetically connected to one end of the refrigerant pipeline 2. The other end of the refrigerant pipeline 2 passes through the inside of the condenser 3 used to cool the refrigerant. After the refrigerant pipeline 2 outputs through the condenser 3, the output end of the refrigerant pipeline 2 is fixedly connected to the liquid receiver dryer 4. The output end of the refrigerant pipeline 2 is fixedly connected to the input end of the thermostatic expansion valve 6, and a high-pressure sensor 5 is provided between the liquid receiver dryer 4 and the high-pressure sensor 5. The refrigerant enters the evaporator 7 through the refrigerant pipeline 2. The inside of the compressor body 1 includes a compressor motor unit 8 and a compressor control part. The inside of the evaporator 7 is provided with a filter screen plate 71. The outside of the filter screen plate 71 is provided with a fan 73. The outside of the fan 73 is provided with a support rod 72 for supporting and installing. One end of the outside of the support rod 72 is fixedly connected to the outer side surface of the evaporator 7. The compressor body 1 compresses the refrigerant. The compressed refrigerant is a high-temperature and high-pressure gas. The condenser 3 is a radiator responsible for cooling the refrigerant. After passing through the condenser 3, the temperature of the refrigerant decreases and changes from a gas to a liquid. At this time, after the refrigerant comes out of the condenser 3, the refrigerant flows into the liquid receiver dryer 4 to absorb the moisture and impurities in the refrigerant and store the refrigerant, making the refrigerant flow more smoothly to the thermostatic expansion valve 6. After the refrigerant is ejected from the thermostatic expansion valve 6, the refrigerant is in a gaseous and liquid state at this time. After being ejected from the thermostatic expansion valve 6, the refrigerant flows into the evaporator 7. In the evaporator 7, the refrigerant absorbs heat, and the liquid cooling medium in the refrigerant vaporizes into a gas state. At this time, the refrigerant absorbs heat, causing the temperature of the evaporator 7 and the surrounding air to decrease. And at this time, the cold air is blown into the vehicle by the fan 73 to cool the vehicle. After the refrigerant comes out of the evaporator 7, it flows into the compressor body 1 to enter the next cycle, realizing the cyclic cooling of the vehicle interior.

[0039] Embodiment 2

[0040] Refer to the appendix Figure 1-16, a motor module for an air conditioner, which is based on the above-mentioned energy-saving vehicle air conditioner. The motor module for the air conditioner includes a compressor motor unit 8 and a support base 81 installed inside the compressor body 1. The compressor motor unit 8 is fixedly installed at the upper end of the support base 81. The compressor motor unit 8 includes a motor housing 82. A heat-conducting ring tube 84 is integrally coated and installed on the inner surface of the motor housing 82. The front end cover 821 and the rear end cover 822 are respectively fixedly installed at both ends of the motor housing 82 through bolts. A control box 823 is fixedly installed on the outer surface of the upper end of the motor housing 82, and heat dissipation air pipes 824 are respectively fixedly installed on both sides of the motor housing 82. The inner surfaces of the centers of the front end cover 821 and the rear end cover 822 are respectively penetrated and connected with a rotating shaft 83. A rotor assembly 831 is fixedly connected to the outer surface of the center of the rotating shaft 83. A stator assembly 832 is arranged outside the rotor assembly 831. An air-cooling fan 10 is fixedly installed on the outer surface of the inner side of the rotating shaft 83 close to the front end cover 821. A buffer and noise reduction mechanism 9 installed on the inner side of the motor housing 82 is arranged outside the air-cooling fan 10. By adding a spiral sleeve ring 8321 in the inner side of the stator assembly 832, the cooling medium is introduced into the inside of the stator assembly 832 to perform liquid cooling circulation to quickly cool down the motor module. The air-cooling fan 10 is used to realize the air-cooling heat dissipation of the motor itself. And a buffer and noise reduction mechanism 9 for noise reduction and buffering is installed on the inner side of the motor housing 82. By jointly cooperating with the two methods of air-cooling and oil-cooling, the heat can be input to the outside through the cooling medium to reduce the temperature of the motor, solving the problem that the existing cooling structure cannot efficiently cool down the stator core and the whole motor module, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption during the operation of the motor module.

[0041] Embodiment 3

[0042] Refer to the appendix Figure 1-16, on the basis of Embodiment 2, in order to achieve smooth rotation of the rotating shaft 83 and sealing effects at both ends, bearing seats 8222 are respectively rotatably connected to the outer surfaces of both ends of the rotating shaft 83. There are two groups of bearing seats 8222, and the outer surfaces of the two groups of bearing seats 8222 are fixedly connected to the inner walls of the front end cover 821 and the rear end cover 822. A bearing end cover 8221 is fixedly installed outside one end of the bearing seat 8222 close to the rear end cover 822. By adding and arranging bearing seats 8222 at both ends of the rotating shaft 83 and at the positions connected to the inner wall of the motor housing 82, the smooth effect during the rotation of the rotating shaft 83 can be increased. And by adding and arranging a bearing end cover 8221 rotatably connected to the outer surface of the rotating shaft 83 outside the bearing seat 8222, the protection of the bearing end cover 8221 can be realized, avoiding or reducing contact with the outside air, reducing the overall wear of the bearing seat 8222, and extending the overall service life of the rotating shaft 83. In order to achieve the penetration of the cooling circulating oil into the structure with a large heat generation amount of the stator assembly 832 and transfer the heat more effectively, a heat dissipation support plate 8322 is fixedly installed on the inner circumferential surface of the stator assembly 832. The heat dissipation support plate 8322 is arranged in an equidistant array with the rotating shaft 83 as the central axis. A spiral sleeve 8321 is fixedly installed on the inner surface of the heat dissipation support plate 8322. The spiral sleeve 8321 is integrally distributed in a spiral hollow tubular structure inside the stator assembly 832. A circulating pump 85 is fixedly installed at the output end of the stator assembly 832. The circulating pump 85 is fixedly installed on the inner wall of one end of the motor housing 82. The output end of the circulating pump 85 is fixedly connected to a heat exchange tube 851. The other end of the heat exchange tube 851 is hermetically connected to a connecting ring tube 852. The output end of the connecting ring tube 852 penetrates through the inner wall of the circulating channel 8211 fixedly connected to the upper end of the motor housing 82, and the output end of the connecting ring tube 852 extends into the inside of a circulating liquid tank 853 fixedly installed on the upper surface of the support seat 81. The output end of the circulating liquid tank 853 is penetrated and connected with a spiral tube 854. The other end of the spiral tube 854 is hermetically connected to a liquid inlet through pipe 855. And one end of the liquid inlet through pipe 855 far from the spiral tube 854 penetrates through the inner wall of the heat dissipation hollow tube 824 and extends into the inside of the spiral sleeve 8321. An auxiliary heat dissipation component is fixedly added to the inner surface of the heat dissipation hollow tube 824. The auxiliary heat dissipation component includes a heat dissipation fin group 8241. The heat dissipation fin group 8241 is arranged in an equidistant array with the central axis of the motor housing 82. Hollow ring grooves 8242 for promoting air flow are respectively opened on the heat dissipation fin group 8241;

[0043] When it is necessary to cool the motor by oil cooling, a non-conductive and non-magnetic cooling medium is filled into the interior of the circulation liquid tank 853. At this time, while the cooling medium circulates inside the spiral sleeve ring 8321 through the heat exchange tube 851, the connecting ring tube 852, the spiral tube 854 and the liquid inlet pipe 855, the sealing effect of the circulating flow is ensured, and the overall airtightness is increased. In addition, the spiral sleeve ring 8321 is spirally distributed at the deep structural positions of the stator assembly 832 and the rotor assembly 831, ensuring that the contact area between the cooling medium and the interior of the stator assembly 832 is larger, thereby accelerating the cooling effect of the motor. Cooperating with the uniform arrangement of the heat dissipation support fin plates 8322, while supporting the spiral sleeve ring 8321, it can uniformly cool the circulating cooling oil inside the spiral sleeve ring 8321. When the circulation pump 85 is driven, the connecting ring tube 852 sucks the cooling medium inside the circulation liquid tank 853. At this time, it enters the interior of the spiral sleeve ring 8321 through the heat exchange tube 851, and the cooling medium circulating through the spiral sleeve ring 8321 then flows back into the interior of the circulation liquid tank 853 through the liquid inlet pipe 855 and the spiral tube 854, circulating reciprocally. The spiral tube 854 is in a spiral shape inside the circulation liquid tank 853. At this time, heat is dissipated from the surface of the spiral tube 854, and the heat dissipation fin group 8241 conducts and cools the dissipated heat, further solving the problem that the existing cooling structure cannot efficiently cool and lower the temperature of the stator core and the entire motor module, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption during the operation of the motor module.

[0044] Embodiment 4

[0045] Refer to the appendix Figure 1-16 , on the basis of Embodiment 3, in order to reduce the noise and vibration generated during the operation of the air-cooled fan 10, a buffer and noise reduction mechanism 9 is added in this embodiment:

[0046] The buffering noise reduction mechanism 9 includes a noise reduction ring plate 91 installed inside the front end cover 821, and the outer ring surface of the noise reduction ring plate 91 is evenly provided with card grooves 911, and an M-shaped card block 912 is fixedly connected to the inner wall of the card groove 911. The M-shaped card block 912 is an "M"-shaped block structure as a whole, and the outer surface of the M-shaped card block 912 is adapted to the inner wall of the card groove 911 in a one-to-one correspondence. The outer surface of the side of the M-shaped card block 912 away from the card groove 911 is fixedly connected to the inner wall of the motor housing 82, and an elastic buffer 92 is fixedly installed on the inner surface of the noise reduction ring plate 91, and a sound-absorbing hollow ring plate 93 is fixedly connected to the inner surface of the elastic buffer 92. Side plates 931 are fixedly installed on the outer surfaces of both sides of the sound-absorbing hollow ring plate 93, and the inner surface of the sound-absorbing hollow ring plate 93 is provided with sound-absorbing fibers. The side panels 931 and the inner sides of the sound-absorbing hollow ring plate 93 are provided with trapezoidal sound collecting buckets 941, which are fixedly mounted on the inner ring surface of the sound-absorbing hollow ring plate 93, and the inner surfaces of the trapezoidal sound collecting buckets 941 are respectively fixedly mounted with conical sound absorbing buckets 942, and the overall shape of the conical sound absorbing buckets 942 is a funnel-shaped structure that is wide inside and narrow outside, and a metal spring strip 9421 is hinged on the inner wall of the conical sound absorbing bucket 942, and a sound impact plate 9422 is hinged on the other end of the metal spring strip 9421, and the metal spring strip 9421 and the sound impact plate 9422 are respectively arranged in an array equidistantly on the central axis of the conical sound absorbing bucket 942;

[0047] When the motor module is in operation, the shaft 83 rotates, and the air-cooling fan 10 connected to the shaft 83 rotates to cool the inside of the motor. At this time, the sound-absorbing fiber strip 94 absorbs the noise generated when the air-cooling fan 10 is driven, and the sound is transmitted to the inside of the trapezoidal sound collecting bucket 941 through the sound-absorbing hollow ring plate 93. During the operation of the air-cooling fan 10, the metal spring strip 9421 produces elastic shaking, and drives the sound-collision plate 9422 to vibrate back and forth, refracting and reducing the absorbed noise, and finally absorbing and eliminating it through the sound-absorbing hollow ring plate 93. Under the action of shaking, by adding a device The elastic buffer 92 can ensure the overall stability of the silencer hollow ring plate 93 while weakening the jitter of the air-cooling fan 10 during rotation. The reason why the M-shaped block 912 and the slot 911 are matched with each other is to achieve stability of the noise reduction ring plate 91 and avoid displacement. The energy consumption of the motor during operation is reduced by noise reduction and buffering and shock absorption, thereby achieving effective energy saving. It further solves the problem that the existing cooling structure cannot achieve efficient cooling of the stator core and the motor module as a whole, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption of the motor module during operation.

[0048] Embodiment 5

[0049] Refer to the attached Figure 1-16, on the basis of Embodiment 4, this embodiment adds:

[0050] The overall shape of the circulation channel 8211 is an annular hollow tubular structure, and heat dissipation fins are evenly arranged outside the circulation channel 8211. The reason for evenly inserting heat dissipation ring fins outside the circulation channel 8211 is to accelerate heat exchange and cooling of the oil circulating inside the connecting ring pipe 852, and increase the heat dissipation area of the oil, further solving the problem that the existing cooling structure cannot efficiently cool and lower the temperature of the stator core and the entire motor module, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption during the operation of the motor module.

[0051] Embodiment 6

[0052] Refer to the appendix Figure 1-16 , on the basis of Embodiment 5, this embodiment adds:

[0053] Hollow slots are also preset on the surface of the heat dissipation fin group 8241. There are two groups of hollow slots, and the two groups of hollow slots are in an "L"-shaped hollow slot structure. The hollow slots are mirror-symmetrically distributed with respect to the hollow ring groove 8242. The reason for opening the hollow slots is that on the one hand, it enhances the heat dissipation effect inside the heat dissipation hollow tube 824, and on the other hand, it also saves raw materials and reduces production costs, effectively cooling the oil inside the spiral tube 854 through which the heat dissipation hollow tube 824 is inserted, increasing the heat dissipation area, and further solving the problem that the existing cooling structure cannot efficiently cool and lower the temperature of the stator core and the entire motor module, resulting in high energy consumption of the air conditioner, thereby reducing the overall energy consumption during the operation of the motor module.

[0054] The working principle and usage process of the present invention:

[0055] First, a non-conductive and non-magnetic cooling medium is filled into the interior of the circulating liquid tank 853, and at this time, the cooling medium circulates into the interior of the spiral collar 8321 through the heat exchange tube 851, the connecting ring tube 852, the spiral tube 854 and the liquid inlet tube 855, while ensuring the sealing effect of the circulation and increasing the overall air tightness. In addition, the spiral collar 8321 is spirally distributed in the deep structural position of the stator assembly 832 and the rotor assembly 831, ensuring that the cooling medium has a larger internal contact area with the stator assembly 832, thereby accelerating the cooling effect of the motor. Then, with the uniform arrangement of the heat dissipation support plate 8322, the spiral collar 8321 is supported while the uniform cooling of the circulating cooling oil in the spiral collar 8321 can be achieved. When the circulating pump 85 is driven, the connecting ring tube 852 draws the cooling medium into the circulating liquid tank 853. At this time, it passes through the heat exchange tube 851 and enters the interior of the spiral collar 8321, and At this time, the cooling medium circulating through the spiral ring 8321 flows to the inside of the circulating liquid tank 853 through the liquid inlet pipe 855 and the spiral tube 854, and circulates back and forth. The spiral tube 854 adopts a spiral manner inside the circulating liquid tank 853. At this time, the surface of the spiral tube 854 dissipates heat, and the heat dissipation fin group 8241 conducts and cools the dissipated heat. In addition, the shaft 83 rotates, and the air-cooling fan 10 connected to the shaft 83 rotates to cool the inside of the motor. At this time, the sound-absorbing fiber strip 94 absorbs the noise generated when the air-cooling fan 10 is driven, and the sound is transmitted to the inside of the trapezoidal sound receiving bucket 941 through the sound-absorbing hollow ring plate 93. During the operation of the air-cooling fan 10, the metal spring strip 9421 produces elastic shaking, and drives the sound impact plate 9422 to shake back and forth, refracting and reducing the absorbed noise, and reducing the energy consumption of the motor during operation by noise reduction and buffering and shock absorption, thereby achieving effective energy saving of the vehicle air conditioner and the air-conditioning motor module.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
