Description

Technical Field

[0001] This invention belongs to the field of automotive refrigeration technology, and specifically relates to a low-loss automatic temperature control automotive air conditioning condenser. Background Technology

[0002] The automotive condenser is a component of the refrigeration system and a type of heat exchanger. It converts gas or vapor into liquid and rapidly transfers heat from the copper pipes to the air near the pipes. The condenser's function is to cool the high-temperature, high-pressure refrigerant vapor discharged from the compressor, causing it to condense into liquid, high-pressure refrigerant.

[0003] Most automotive condensers on the market are currently installed at the front of the vehicle. When the car is moving, the fan at the front of the condenser accelerates airflow, driving air through the radiator fins. At this time, gravel and impurities in the air can easily get stuck between the radiator fins, preventing smooth airflow and affecting heat exchange efficiency. This increases the energy consumption of the air conditioning compressor, so it is necessary to clean the debris between the radiator fins in a timely manner. It should be noted that since the engine compartment is behind the condenser, when cleaning the debris between the radiator fins, it is necessary to prevent debris from entering the engine compartment and causing electrical malfunctions or other problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a low-loss automatic temperature control automotive air conditioning condenser to solve the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solution: A low-loss automatic temperature-controlled automotive air conditioning condenser, comprising a housing and a rear frame mounted on the back of the housing, a copper tube mounted on the housing, a fin assembly mounted inside the housing, the fin assembly being slidably connected to the wall of the copper tube, an inlet valve mounted at the liquid inlet end of the copper tube, an outlet valve mounted at the liquid outlet end, and a limiting component mounted on the side wall of the housing; a spring is fixedly mounted on each fin group in the fin assembly, and each fin group abuts against the adjacent fin on the other side via the spring; the rear frame... The cleaning assembly includes a U-shaped frame slidably installed inside the rear frame, a push plate slidably installed inside the U-shaped frame, an inclined groove installed on the U-shaped frame, and the push plate slidingly engaging with the inclined groove via a guide rod. A return spring is installed inside the inclined groove. A power assembly is installed on the rear frame, including a stepper motor and a second motor. The stepper motor drives the U-shaped frame to move from top to bottom via a lead screw, and the second motor drives the push plate to slide along the inclined groove via a cam, so that the push plate inserts into the gap between each group of fins one by one and presses the fins at the bottom of the push plate.

[0006] As a further optimization or improvement of this solution, the limiting component includes an external limiting member on the side wall of the mounting housing, with a cavity inside the external limiting member. The cavity is connected to a push plate via a compression spring, and the push plate engages each set of fins via a slot on it.

[0007] As a further optimization or improvement of this solution, an electromagnetic chuck is installed on the inner wall of the cavity, and a magnetic block is installed on the slot. The electromagnetic chuck is energized to attract the magnetic block.

[0008] As a further optimization or improvement of this solution, a longitudinal guide groove is provided on the rear frame, and a guide bar is installed on the U-shaped frame, with the guide bar slidably connected to the longitudinal guide groove.

[0009] As a further optimization or improvement of this solution, a support plate is installed on the U-shaped frame, a second motor is fixedly installed on the support plate, a transmission plate is slidably installed inside the support plate, and a guide rod on the push plate passes through the inclined groove and slides with the transverse groove on the transmission plate.

[0010] As a further optimization or improvement of this solution, a slider is installed on the transmission plate and a longitudinal groove is installed on the support plate, with the slider and the longitudinal groove slidingly engaged.

[0011] As a further optimization or improvement to this solution, a fan is mounted on the front of the housing, and each set of fins is connected to a copper tube through a sliding sleeve made of a high thermal conductivity material.

[0012] The beneficial effects of this invention are: (1) In this invention, a stepper motor drives a U-shaped frame to move intermittently from top to bottom via a lead screw. At the same time, the second motor intermittently presses the transmission plate via a cam. The transmission plate drives the push plate to move synchronously via a guide rod. At this time, through the cooperation of the guide rod and the inclined groove, the push plate inserts into the fin gap and pushes out the debris stuck in the fin gap from back to front, cleaning the debris between the fin gaps, reducing the energy consumption of the air conditioning compressor, and preventing impurities from entering the cabin through the fins and causing electrical faults and other problems.

[0013] (2) Before the push plate of the present invention is inserted into the fin, the electromagnetic chuck is energized and the electromagnetic chuck attracts the magnetic block on the push plate, causing the push plate to move into the cavity, the fin group limit is released, and the compression spring is compressed; with the cooperation of the push plate and the inclined groove, the push plate is inserted into the fin gap and the push plate moves downward. At this time, the push plate presses the fin below the push plate, the spring between the fins is compressed, and the fin spacing below the push plate is reduced. This prevents the debris from being pushed out by the push plate and falling. The flowing gas pushes the falling debris towards the fin group, causing the cleaned debris to get stuck in the gap between the fin groups again.

[0014] (3) When the push plate of the present invention presses the fins below the push plate, if there are still hard objects or impurities in the gap between the fins below the push plate, the fins with impurities will transmit the pressure to the fins below, ensuring that the gap between the fins below the push plate is reduced. Since the springs between each group of fins can transmit the pressure of the push plate downward, the hard objects or impurities stuck between the fins will not damage the fins when the fins are pressed.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] See Figures 1-11 A low-loss automatic temperature-controlled automotive air conditioning condenser includes a housing 1 and a rear frame 7 mounted on the back of the housing 1. A copper tube 3 is mounted on the housing 1, and a fin assembly 2 is installed inside the housing 1. The fin assembly 2 is slidably connected to the wall of the copper tube 3. An inlet valve 4 is installed at the liquid inlet end of the copper tube 3, and an outlet valve 5 is installed at the liquid outlet end. A limiting component 6 is installed on the side wall of the housing 1. Each fin in the fin assembly 2 is fixedly mounted with a spring, and each fin abuts against the adjacent fin on the other side via the spring. A cleaning component 9 is mounted on the rear frame 7. The cleaning component 9 includes a U-shaped frame 901 slidably mounted inside the rear frame 7. A push plate 902 is slidably installed inside the U-shaped frame 901. An inclined groove 905 is installed on the U-shaped frame 901. The push plate 902 slides with the inclined groove 905 through a guide rod 908. A return spring 914 is installed inside the inclined groove 905. A power assembly 8 is installed on the rear frame 7. The power assembly 8 includes a stepper motor 801 and a second motor 804. The stepper motor 801 drives the U-shaped frame 901 to move from top to bottom through a lead screw 802. The second motor 804 drives the push plate 902 to slide along the inclined groove 905 through a cam 805, so that the push plate 902 is inserted into the gap between each group of fins one by one and presses the fins at the bottom of the push plate 902.

[0030] Specifically, a longitudinal guide groove 913 is provided on the rear frame 7, and a guide bar 912 is installed on the U-shaped frame 901. The guide bar 912 is slidably connected to the longitudinal guide groove 913.

[0031] Specifically, a support plate 907 is installed on the U-shaped frame 901, a motor 804 is fixedly installed on the support plate 907, a transmission plate 903 is slidably installed inside the support plate 907, and a guide rod 908 on the push plate 902 passes through the inclined groove 905 and slides in cooperation with the transverse sliding groove 909 on the transmission plate 903.

[0032] Specifically, a slider 910 is installed on the transmission plate 903, and a longitudinal groove 911 is installed on the support plate 907. The slider 910 and the longitudinal groove 911 are in sliding engagement.

[0033] It should be noted that the rear frame 7 is installed on the back of the housing 1, and the back of the rear frame 7 is the engine compartment. When the vehicle is moving, the outside air flows through the fin assembly 2. The airflow carries away heat as it passes through the fin assembly 2, accelerating the cooling and condensation of the refrigerant inside the copper tube 3. During this process, gravel and impurities in the air will inevitably get stuck in the gaps between the fin assembly 2.

[0034] The present invention uses a power component 8 to drive a cleaning component 9 to be inserted from back to front into the gap between each set of fins, thereby pushing out the debris in the fins from the front end of the housing 1. The specific operation is as follows: Stepper motor 801 drives U-shaped frame 901 to move intermittently from top to bottom via lead screw 802. At the same time, motor 804 intermittently presses transmission plate 903 via cam 805. Transmission plate 903 drives push plate 902 to move synchronously via guide rod 908. At this time, through the cooperation of guide rod 908 and inclined groove 905, push plate 902 inserts into fin gap, pushing out the debris stuck in the fin gap from back to front. While cleaning the debris between the fin gaps, it prevents impurities from entering the nacelle through the fins and causing electrical faults and other problems.

[0035] It should be noted that when debris is pushed out and falls by the push plate 902, because the external air flows towards the fin assembly 2 when the vehicle is in motion, the flowing gas pushes the falling debris towards the fin assembly 2, which can easily cause the cleaned debris to get stuck again at the bottom fin assembly 2 or enter the cabin through the fin assembly 2.

[0036] Therefore, before the push plate 902 of the present invention is inserted into the fins, the electromagnetic chuck 606 is energized, and the electromagnetic chuck 606 attracts the magnetic block 607 on the push plate 605, causing the push plate 605 to move into the cavity 602, the fin group 2 is released from its limit, and the compression spring 603 is compressed; with the cooperation of the push plate 902 and the inclined groove 905, while the push plate 902 is inserted into the fin gap, the push plate 902 moves downward. At this time, the push plate 902 presses the fins below the push plate 902, the springs between the fins are compressed, and the fin spacing below the push plate 902 is reduced, so as to prevent the debris from being pushed out by the push plate 902 and falling, and the flowing gas pushing the falling debris towards the fin group 2, causing the cleaned debris to get stuck in the gap between the fin groups 2 again.

[0037] When the push plate 902 presses down on the fins below the push plate 902, if there are still hard objects or impurities in the gap between the fins below the push plate 902, the fins with impurities will transmit the pressure to the fins below, ensuring that the gap between the fins below the push plate 902 is reduced. At the same time, the springs between each group of fins can transmit the pressure of the push plate 902 downwards, preventing hard objects or impurities stuck between the fins from damaging the fins when they are pressed.

[0038] Furthermore, when the fins below the push plate 902 are pressed, the spacing between the fins decreases, causing the fins near the blockage point of the copper tube 3 to be densely arranged, improving the heat dissipation efficiency of the copper tube 3 near the blockage point, and avoiding the impact of gas-liquid two-phase mixing on the copper tube 3 in the blockage area.

[0039] It should be noted that the stepper motor 801 drives the U-shaped frame 901 to move in a unit of distance between each set of fins via the lead screw 802. The second motor 804 drives the cam 805 to complete one revolution, which is the interval pressing stroke, ensuring that the push plate 902 can clean the debris between each set of fins from top to bottom.

[0040] See Figures 4-5 The limiting component 6 includes an external limiting member 601 on the side wall of the mounting housing 1. The external limiting member 601 has a cavity 602 inside. The cavity 602 is connected to a push plate 605 through a compression spring 603. The push plate 605 engages each set of fins through a slot 604 on it.

[0041] Specifically, an electromagnetic chuck 606 is installed on the inner wall of the cavity 602, and a magnetic block 607 is installed on the slot 604. When the electromagnetic chuck 606 is energized, it attracts the magnetic block 607.

[0042] It should be noted that during normal use, the electromagnetic chuck 606 is de-energized, and the push plate 605 is engaged with the fins under the action of the compression spring 603, fixing each group of fins; when it is necessary to clean the debris between the fins, the electromagnetic chuck 606 is energized, and the electromagnetic chuck 606 attracts the magnetic block 607 on the push plate 605, causing the push plate 605 to move into the cavity 602, and the fin group 2 is released from its limit.

[0043] See Figure 5 and Figure 9 The front of the housing 1 is equipped with a fan (not shown in the attached figure), and each set of fins is connected to the copper tube 3 through a sliding sleeve made of high thermal conductivity material.

[0044] It should be noted that a sliding sleeve made of high thermal conductivity material is installed on the fins. The fins are slidably connected to the copper tube 3 through the sliding sleeve. The sliding sleeve increases the contact area between the fins and the copper tube 3, further improving the heat dissipation efficiency of the copper tube 3. The high thermal conductivity material can be copper. A baffle 904 is installed in front of the lead screw 802, and a strip-shaped through groove 906 is installed on the U-shaped frame 901. The strip-shaped through groove 906 slides with the baffle 904, and the baffle 904 protects the transmission connection between the lead screw 802 and the U-shaped frame 901. The inlet valve 4 and the outlet valve 5 are automatic temperature control valves, which can automatically control the flow rate according to the refrigerant temperature.

[0045] The implementation principle of this invention is as follows: The present invention uses a power component 8 to drive a cleaning component 9 to be inserted from back to front into the gap between each set of fins, thereby pushing out the debris in the fins from the front end of the housing 1. The specific operation is as follows: Stepper motor 801 drives U-shaped frame 901 to move intermittently from top to bottom via lead screw 802. At the same time, motor 804 intermittently presses transmission plate 903 via cam 805. Transmission plate 903 drives push plate 902 to move synchronously via guide rod 908. At this time, through the cooperation of guide rod 908 and inclined groove 905, push plate 902 inserts into fin gap, pushing out the debris stuck in the fin gap from back to front. While cleaning the debris between the fin gaps, it prevents impurities from entering the nacelle through the fins and causing electrical faults and other problems.

[0046] It should be noted that when debris is pushed out and falls by the push plate 902, because the external air flows towards the fin assembly 2 when the vehicle is in motion, the flowing gas pushes the falling debris towards the fin assembly 2, which can easily cause the cleaned debris to get stuck again at the bottom fin assembly 2 or enter the cabin through the fin assembly 2.

[0047] Therefore, before the push plate 902 of the present invention is inserted into the fins, the electromagnetic chuck 606 is energized, and the electromagnetic chuck 606 attracts the magnetic block 607 on the push plate 605, causing the push plate 605 to move into the cavity 602, the fin group 2 is released from its limit, and the compression spring 603 is compressed; with the cooperation of the push plate 902 and the inclined groove 905, while the push plate 902 is inserted into the fin gap, the push plate 902 moves downward. At this time, the push plate 902 presses the fins below the push plate 902, the springs between the fins are compressed, and the fin spacing below the push plate 902 is reduced, so as to prevent the debris from being pushed out by the push plate 902 and falling, and the flowing gas pushing the falling debris towards the fin group 2, causing the cleaned debris to get stuck in the gap between the fin groups 2 again.

[0048] When the push plate 902 presses down on the fins below the push plate 902, if there are still hard objects or impurities in the gap between the fins below the push plate 902, the fins with impurities will transmit the pressure to the fins below, ensuring that the gap between the fins below the push plate 902 is reduced. At the same time, the springs between each group of fins can transmit the pressure of the push plate 902 downwards, preventing hard objects or impurities stuck between the fins from damaging the fins when they are pressed.

[0049] It should be noted that the stepper motor 801 drives the U-shaped frame 901 to move in a unit of distance between each set of fins via the lead screw 802. The second motor 804 drives the cam 805 to complete one revolution, which is the interval pressing stroke, ensuring that the push plate 902 can clean the debris between each set of fins from top to bottom.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
