Description

Technical Field

[0001] The present invention relates to the technical field of automobile air conditioning, and in particular to a new energy automobile air conditioning refrigeration and heat exchange component. Background Art

[0002] New energy vehicles mainly include pure electric vehicles and hybrid vehicles. Since new energy vehicles can directly use electricity to drive car air conditioners, the cost of using air conditioners is lower and the air conditioners can be used for longer periods of time, allowing air conditioners to play a greater role in severe cold and hot weather.

[0003] However, in the rainy areas in southern my country, the air humidity is relatively high, which makes it easy for the evaporator in the automobile air conditioning system to form droplets and frost inside when in use. Frosting will cause the equipment to be more easily damaged and reduce the heat exchange efficiency of the evaporator, making it difficult for the air conditioner to obtain a good user experience. The droplets generated accumulate inside the evaporator for a long time, which is not only easy to corrode the equipment but also easy to breed bacteria. The droplets will also cause discomfort to the members after being ejected with the airflow. In addition, the pipes used to transport refrigerant and the fins used for heat exchange in the existing evaporator equipment are mainly welded as a whole. After local damage occurs, they need to be replaced as a whole, so the maintenance cost is high. The existing evaporator structure is not convenient to disassemble, which makes maintenance difficult. The patent number is CN108645078A, and the patent name is "A new energy vehicle air conditioning refrigeration and heat exchange component". Although the condenser tube used to transport refrigerant and the fins used for heat exchange are separated, so that the two parts can be replaced and maintained separately, reducing the maintenance cost, it cannot solve the problems of easy frost and condensation droplets in high humidity environments through a more reasonable structural design.

[0004] Therefore, we need a new energy automobile air conditioning refrigeration and heat exchange component to solve the problem that the existing automobile air conditioning is prone to reduced heat exchange efficiency and high maintenance cost due to frost in areas with high humidity, which can effectively improve the heat exchange efficiency and reliability of automobile air conditioning.

However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0039] For example, see Figures 1 to 11The present invention provides a technical solution: a new energy vehicle air conditioning refrigeration heat exchange component, comprising a mounting frame 1, a flow guide device 6, a first heat exchange device 5, a second heat exchange device 4 and a liquid collecting tank 16, a front sealing plate 11 and a rear sealing plate 20 are respectively fixedly installed at the front and rear ends of the mounting frame 1, and an intake pump 12 is installed on the front sealing plate 11, an air filter device 19 is installed at the exhaust port of the intake pump 12, and an exhaust pipe 22 is fixedly installed on the rear sealing plate 20, the air filter device 19 is sequentially composed of a primary filter screen, a dust bag, an activated carbon filler layer and a high-efficiency filter screen connected in series from the side connected to the intake pump 12 to the side connected to the cooling chamber 24, and the side of the mounting frame 1 A shock absorbing device 2 is fixedly installed on the surface, and the shock absorbing device 2 includes a shock absorbing connecting column 203 fixedly installed on the outside of the mounting frame 1, a shock absorbing connecting plate 201 is sleeved on the outside of the shock absorbing connecting column 203, and a rubber block 202 is sleeved between the shock absorbing connecting column 203 and the shock absorbing connecting plate 201. The shock absorbing device 2 can damp the vibration of the mounting frame 1 during operation through the rubber block 202. At the same time, the sealing structure composed of the mounting frame 1, the front sealing plate 11 and the rear sealing plate 20 can also reduce the internal noise. Further, sound absorbing materials can be arranged on the inside and outside of the mounting frame 1, the front sealing plate 11 and the rear sealing plate 20 to further reduce the noise.

[0040] See also Figure 3 , Figure 4 , Figure 6 and Figure 7A pair of side fixing plates 8 are fixedly installed in the mounting frame 1, and a cooling chamber 24 is formed between the side fixing plates 8, the mounting frame 1, the front sealing plate 11 and the rear sealing plate 20. A flow guide device 6 for transporting refrigerant is formed in the cooling chamber 24 by staggered series connection of a reversing elbow 602 and a straight pipe 603. The length of the flow guide device 6 is set according to the use requirements, and generally has at least two straight pipes 603 and one reversing elbow 602. Anti-slip limit blocks 7 are fixedly installed on the front sealing plate 11 and the rear sealing plate 20, and the anti-slip limit blocks 7 are used to snap into The mounting frame 1 and the side fixing plate 8 are used to prevent the side fixing plate 8 from deforming and falling off. The reversing elbow 602 is fixedly installed on the side fixing plate 8, and the reversing elbow 602 and the straight conduit 603 are plugged and installed and glued and sealed. When the side fixing plate 8 is long, the area in the middle of the side fixing plate 8 may produce a large vibration under the influence of vibration, thereby gradually loosening between the mounting frame 1 and the reversing elbow 602. The setting of the anti-slip limit block 7 can effectively utilize the anti-slip limit block 7 and the straight conduit 603 to achieve The side fixing plate 8 is clamped to prevent the side fixing plate 8 from loosening or falling off, which effectively improves the reliability of the equipment sealing. The straight conduit 603 at the head and tail ends of the flow guide device 6 is respectively sealed and connected with the inlet interface 601 and the outlet interface 604. The mounting frame 1 is provided with an inlet pipe 9 for connecting the inlet interface 601 and the expansion valve, and the mounting frame 1 is provided with a outlet pipe 18 for connecting the outlet interface 604 and the compressor. By connecting the flow guide device 6 with the expansion valve and the compressor, the flow guide device 6 can be made 6, an expansion valve, a compressor and a condenser together constitute an automobile air-conditioning system, thereby realizing a complete refrigeration process. The straight conduit 603 includes a tube body 6031, and an inner flow channel 6032 for conveying refrigerant is arranged in the tube body 6031. A heat-conducting needle 6033 for exchanging heat with the refrigerant is arranged between the inner walls of the tube body 6031. The setting of the heat-conducting needle 6033 can effectively increase the heat exchange area between the tube body 6031 and the refrigerant, thereby improving the heat exchange efficiency and facilitating the transfer of heat to the refrigerant through the main sleeve 504.

[0041] See also Figure 3 and Fig. 9 The first heat exchange device 5 includes a main sleeve 504 installed on the straight conduit 603, and the main sleeves 504 are connected and isolated by the heat conductive plate 503 to form an air flow channel 505, each air flow channel 505 is arranged in an array with at least three heat conductive sheets 502, and the heat conductive sheets 502 are fixedly connected to the surface of the main sleeve 504, and the gaps between the heat conductive sheets 502 are at the millimeter level, so that the additional contact area formed between the heat conductive sheets 502 and the air can be used to improve the heat exchange efficiency, which facilitates the heat in the air to be transferred to the main sleeve 504 through the heat conductive sheet 502, and then transferred to the straight conduit 603 through the main sleeve 504, and finally the heat is transferred to the refrigerant by the straight conduit 603.

[0042] See also Figure 3 , Figure 4 and Fig.11 The second heat exchange device 4 includes a bonding plate 401 that is bonded to the main sleeve 504, and a plug-in plate 402 is provided on the bonding plate 401 to be inserted into the air flow channel 505. The bonding plate 401 and the plug-in plate 402 are arranged to facilitate heat transfer to the main sleeve 504. At least two mesh plates 404 are arranged in an equal gap array on the outside of the bonding plate 401, and the mesh plates 404 are connected to the bonding plate 401 through a heat conductive connecting sheet 403. The mesh plates 404 arranged in the array are arranged between There are gaps between the mesh plates 404, and the air can complete the heat exchange with the mesh plates 404 at the gaps between the mesh plates 404. Then, the heat will be transferred to the heat-conducting connecting sheet 403 through the mesh plates 404, and then transferred to the bonding plate 401 and the plug-in board 402 through the heat-conducting connecting sheet 403, and then the heat will be transferred to the straight conduit 603 through the bonding plate 401 and the plug-in board 402. The air that has completed the heat exchange can move toward the outside of the second heat exchange device 4 through the mesh holes on the mesh plates 404 until it enters the exhaust In the tube 22, it should be noted that the meshes on the adjacent mesh plates 404 are arranged in a staggered manner, which means that when the airflow passes through the meshes on the adjacent mesh plates 404, it must move along the gaps between the mesh plates 404 and transfer heat to the mesh plates 404 during the movement. Moreover, the mesh size on the mesh plates 404 is strictly controlled, which can effectively prevent the passage of droplets, so that the droplets can be isolated in the gaps between the mesh plates 404 and finally move gradually to the liquid collecting tank 16 under the action of gravity and be collected by the liquid collecting tank 16, so that the droplet content in the gas can be effectively reduced. The surface of the tube body 6031 is bent to form a matching groove 6034, and a heat exchange matching protrusion 501 that is fitted with the matching groove 6034 is installed in the main sleeve 504. The setting of the matching groove 6034 and the heat exchange matching protrusion 501 can effectively increase the effective heat exchange area, thereby improving the heat exchange efficiency, and the second heat exchange device 4 is fixedly installed at both the front and rear ends of the first heat exchange device 5.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The mounting frame 1 is provided with a liquid collecting tank 16 at the bottom corresponding to the second heat exchange device 4, and a first liquid drain pipe 13 for draining liquid is installed on the liquid collecting tank 16, and a first liquid drain valve 14 is installed on the first liquid drain pipe 13, and a liquid level sensor 17 for detecting the liquid level in the liquid collecting tank 16 is installed in the liquid collecting tank 16, and the liquid level sensor 17, the first liquid drain valve 14 and the intake pump 12 are electrically connected to the on-board computer, and liquid droplets are collected through the liquid collecting tank 16. When the liquid level sensor 17 detects that enough liquid droplets are collected in the liquid collecting tank 16, the on-board computer opens the first liquid drain valve 14 to discharge the droplets.

[0044] In this embodiment, the refrigerant delivered by the expansion valve will move along the guide device 6 and finally be delivered to the compressor. At the same time, the air intake pump 12 draws air into the air filter device 19 to filter out impurities and then delivers it to the cooling chamber 24 for cooling and finally discharges the cooled air through the exhaust pipe 22. During the cooling of the air in the cooling chamber 24, the air can complete heat exchange with the refrigerant located in the guide device 6 through the first heat exchange device 5 and the second heat exchange device 4. During the heat exchange process, when the water vapor in the air is condensed, the formed droplets will also be collected and discharged, thereby avoiding the presence of droplets affecting the passengers' experience of using the air conditioner. The refrigeration heat exchange component not only has good heat exchange efficiency, but also has simple processing and assembly of parts and components, and is also convenient for maintenance and disassembly. During assembly, it is only necessary to first install the reversing elbow 602 in the side fixing plate 8, and then insert the straight conduit 603 into the main sleeve 504, and then assemble the straight conduit 603, the reversing elbow 602, the inlet port 601 and the outlet port 604 into the required flow guide device 6, and then fix the side fixing plate 8 in the mounting frame 1, and then insert the second heat exchange device 4 into the first heat exchange device 5, and then fix the front sealing plate 11 and the rear sealing plate 20 on the mounting frame 1. Therefore, when the above structure fails, it can be quickly replaced, thereby realizing rapid maintenance, without having to replace the entire evaporator like a traditional evaporator, thereby reducing maintenance costs. On the other hand, the present invention can provide a large heat exchange area through the first heat exchange device 5 and the second heat exchange device 4. , thereby increasing the heat exchange efficiency. When the required cooling effect per unit time is the same, the surface of the first heat exchange device 5 and the second heat exchange device 4 can achieve the same heat exchange effect at a higher surface temperature state. For example, when the same air volume is preset and the preset temperature is 15 degrees Celsius, due to the low heat exchange efficiency of the traditional evaporator surface, only by maintaining the surface at about 3 degrees Celsius can the heat exchange be completed per unit time. In this refrigeration heat exchange component, it is only necessary to maintain the surface of the first heat exchange device 5 and the second heat exchange device 4 at about 10 degrees Celsius to complete the heat exchange in the same time. Since the water vapor frosts less in the environment with higher temperature, the frost on the surface of the first heat exchange device 5 and the second heat exchange device 4 of the present invention is obviously less than the frost on the surface of the traditional evaporator, thereby effectively reducing the harm caused by frost, so that the car can get a better use experience in areas with high humidity. It solves the problem that the existing automobile air conditioner is prone to reduced heat exchange efficiency and high maintenance cost due to frost in areas with high humidity, and can effectively improve the heat exchange efficiency and use reliability of the automobile air conditioner.

[0045] For example 2, please refer to Figure 1 , Figure 2 , Figure 3 and Fig.10On the basis of the first embodiment, a temperature sensor 15 for detecting the temperature in the cooling chamber 24 is installed on the mounting frame 1, and a heater 10 is fixedly installed on the mounting frame 1, a heat conducting plate 503 is installed in close contact with the heat output end of the heater 10, and an exhaust valve 23 is fixedly installed on the exhaust pipe 22, the temperature sensor 15, the heater 10 and the exhaust valve 23 are all electrically connected to the on-board computer, when the refrigeration heat exchange component does not need to work, the user can issue an internal defrost command through the on-board computer, at this time the exhaust valve 23 is temporarily closed, the heater 10 starts to work, and the heat generated by the heater 10 will be transferred to the entire first heat exchange device 5 and the second heat exchange device 4 through the heat conducting plate 503, so that the surface temperature of the first heat exchange device 5 and the second heat exchange device 4 can be higher than the preset temperature, which is higher than the freezing point of water and can generally be set above fifteen degrees Celsius, and the temperature in the cooling chamber 24 can be sensed by the temperature sensor. The device 15 is used for detection, so that the on-board computer can control the working state of the heater 10. During the heating process of the heater 10, the frost originally condensed on the first heat exchange device 5 and the second heat exchange device 4 will be converted into liquid droplets or water vapor, and then the first liquid discharge valve 14 will be opened, and the air intake pump 12 will start to work at the same time. The air intake pump 12 will blow air into the cooling chamber 24 to discharge the liquid droplets and water vapor in the cooling chamber 24 through the first liquid discharge pipe 13, thereby completing the internal defrosting operation. This form of internal defrosting can prevent frost from adhering to the surfaces of the first heat exchange device 5 and the second heat exchange device 4 for a long time to affect the heat exchange efficiency. At the same time, it also avoids various corrosion hazards caused by frosting, improves the service life of the equipment, and further solves the problem that the existing automobile air conditioner is prone to reduce the heat exchange efficiency and high maintenance cost due to frosting in areas with high humidity, which can effectively improve the heat exchange efficiency and reliability of the automobile air conditioner.

[0046] For example 3, please refer to Figure 2 , Figure 3 and Fig.10On the basis of the second embodiment, a mounting shell 21 for connecting the cooling chamber 24 and the exhaust pipe 22 is fixedly mounted on the rear sealing plate 20, and a liquid discharge device 3 for filtering liquid droplets in the airflow is arranged in the mounting shell 21, and the liquid discharge device 3 includes a centrifugal blade 301 rotatably mounted in the mounting shell 21, and the mounting shell 21 is provided with an annular collection groove 303 for collecting liquid droplets at a circumferential position corresponding to the centrifugal blade 301, and the annular collection groove 303 is provided with an annular array at a position in contact with the centrifugal blade 301. At least four arc-shaped isolation sheets 302 are arranged in a row to prevent the droplets from returning to the centrifugal blades 301. A second drain pipe 305 for discharging the droplets is installed on the annular collecting groove 303, and a second drain valve 304 is installed on the second drain pipe 305. The second drain valve 304 is electrically connected to the on-board computer. When the airflow moves from the cooling chamber 24 to the exhaust pipe 22, the airflow will drive the centrifugal blades 301 to rotate. The blades of the centrifugal blades 301 themselves are inclined, so that the droplets in the airflow push the centrifugal blades 301 to rotate. During the process of the centrifugal blade 301, the liquid droplets will adhere to the centrifugal blade 301, and then the liquid droplets will gather on the centrifugal blade 301 and be gradually pushed to the end of the centrifugal blade by the centrifugal force along the centrifugal blade, and then the liquid droplets will be thrown into the annular collection groove 303 under the action of the centrifugal force. Due to the setting of the arc-shaped isolation plate 302, the airflow cannot pass through the arc-shaped isolation plate 302 to bring out the liquid droplets in the annular collection groove 303 again, so the liquid droplets will gradually gather in the annular collection groove 303 to the second drain pipe 305, and finally be regularly discharged by the second drain valve 304, thereby further completing the dehumidification of the airflow. A motor for driving the centrifugal blade 301 can also be installed on the further installation shell 21, so that the motor can drive the centrifugal blade 301 to rotate at a high speed to realize the centrifugal separation of the liquid droplets, which can further improve the separation efficiency of the liquid droplets, further solve the problem that the existing automobile air conditioner is prone to reduced heat exchange efficiency and high maintenance cost due to frost in areas with high humidity, and can effectively improve the heat exchange efficiency and use reliability of the automobile air conditioner.

[0047] Embodiment 4, based on embodiment 3, the present invention further provides a method for using a new energy vehicle air conditioning refrigeration heat exchange component, comprising the following steps:

[0048] Step 1: First, install the reversing elbow 602 in the side fixing plate 8, then insert the straight pipe 603 into the main sleeve 504, and then assemble the straight pipe 603, the reversing elbow 602, the inlet interface 601 and the outlet interface 604 into the required flow guide device 6, then fix the side fixing plate 8 in the mounting frame 1, then insert the second heat exchange device 4 into the first heat exchange device 5, and then fix the front sealing plate 11 and the rear sealing plate 20 on the mounting frame 1, and then connect the flow guide device 6 to the expansion valve and the compressor in the automobile air conditioning system to complete the assembly;

[0049] Step 2: When in use, the air intake pump 12 draws air into the air filter device 19 to filter out impurities, and then sends the air into the cooling chamber 24 for cooling and finally discharges the cooled air through the exhaust pipe 22. During the cooling process of the air in the cooling chamber 24, the air can complete heat exchange with the refrigerant in the guide device 6 through the first heat exchange device 5 and the second heat exchange device 4;

[0050] Step 3: The droplets generated during the heat exchange between air and refrigerant will gather in the liquid collecting tank 16 and be discharged periodically, and the remaining droplets will also be discharged through the drainage device 3.
