Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning system technology, specifically to a dual-medium high-efficiency energy-saving condenser for automotive air conditioning. Background Technology

[0002] An automotive air conditioning system is a device installed in a vehicle to regulate and control the temperature, humidity, airflow speed, and air quality inside the passenger compartment. It mainly consists of a refrigeration system, a heating system, ventilation and air purification devices, and a control system. The functions of an automotive air conditioning system are primarily reflected in the following aspects:

[0003] Temperature Regulation: Cooling: In hot weather, the car's air conditioning system absorbs heat from inside the vehicle through refrigerant circulation and expels it outside, thus cooling the interior. Heating: In cold weather, the system utilizes engine coolant, exhaust heat, or heat generated by the burner to heat the air, which is then delivered into the vehicle by a blower to raise the interior temperature. Humidity Regulation: The car's air conditioning system removes moisture from the air, allowing the dry air to absorb sweat, creating a more comfortable environment. Ventilation: The system has a ventilation function, introducing fresh outside air into the vehicle, maintaining air circulation, preventing windshield fogging, and providing necessary oxygen. Air Purification: The air filter built into the car's air conditioning system filters out dust, pollen, odors, and toxic gases, improving air quality and providing a healthier riding environment for passengers. Improved Driving Safety: By providing a comfortable riding environment, the car's air conditioning system can reduce driver fatigue, thereby improving driving safety.

[0004] However, with the rapid development of the automotive industry and the increasing demands of consumers for driving comfort, optimizing the performance of automotive air conditioning systems has become an important research direction. As a key component of the automotive air conditioning system, the condenser's performance directly affects the system's cooling efficiency and energy efficiency ratio. Traditional automotive air conditioning condensers mostly use a single medium for heat exchange, resulting in low heat exchange efficiency and high energy consumption. Utility Model Content

A limit slide rod is movably connected to the side of the lifting frame away from the transmission screw. A cleaning shaft is rotatably connected to the inner side of the lifting frame via a rotating shaft. A cleaning soft brush roller is fixedly mounted on the outer curved surface of the middle part of the cleaning shaft. A transmission gear is fixedly mounted on the outer curved surface of the side end of the cleaning shaft. A transmission rack is meshed with the inner side of the transmission gear.

[0009] Preferably, a cooling fan is fixedly installed through the middle of the rear mounting frame, and an installation enclosure is fixedly installed on the outer side of the rear end of the rear mounting frame, with installation holes through the four corners of the installation enclosure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a first condenser and a second condenser to form two independent yet cooperative heat dissipation circulation systems. The first condenser uses traditional refrigerant as the heat dissipation medium, while the second condenser introduces coolant as the heat dissipation medium. When the automotive air conditioning system is running, the high-temperature, high-pressure refrigerant gas first enters the first condenser. In the first condenser, the refrigerant exchanges heat with the tube wall and heat sink, transferring heat to the tube wall and heat sink. Simultaneously, the coolant in the second condenser also circulates, absorbing heat transferred from the refrigerant through the tube wall of the first condenser, causing the coolant's own temperature to rise. Due to the coolant's high specific heat capacity, it can absorb a large amount of heat. Furthermore, during circulation, it undergoes secondary heat exchange with the outside air, efficiently dissipating the absorbed heat into the atmosphere. This dual-medium synergistic heat dissipation method significantly improves heat dissipation efficiency, providing a strong guarantee for the efficient operation of the air conditioning system.

[0016] This invention also features a system where, when the drive motor is turned on, it rotates the first synchronous pulley, which in turn drives the second synchronous pulley via a synchronous belt. The second synchronous pulley, in turn, drives the transmission screw, which in turn drives the lifting frame to move vertically via the screw nut. This vertical movement of the lifting frame, in turn, drives the cleaning shaft to move vertically. This vertical movement of the cleaning shaft, in turn, drives the transmission gear to move vertically. This vertical movement of the transmission gear, through the meshing of the transmission gear and the transmission rack, drives the cleaning shaft to rotate. This rotation of the cleaning shaft, in turn, drives the cleaning soft brush roller to rotate. When the cleaning soft brush roller rotates, it cleans the front end of the filter screen vertically. Simultaneously, by activating the nozzle, the cleaning soft brush roller cleans the front end of the filter screen, thus achieving both filtration of the air entering the main frame and convenient cleaning and maintenance of the front end of the filter screen.

A heat sink 10 is fixedly installed inside the main frame 1, and there are several heat sinks 10, which are symmetrically distributed in sequence inside the main frame 1. The first condenser 6 and the second condenser 7 pass through the heat sink 10, so that the heat sink 10 absorbs heat and cools the first condenser 6 and the second condenser 7.

[0025] Two through slots 11 are provided on both sides of the front end of the front mounting frame 2, symmetrically distributed on both sides of the front end of the front mounting frame 2. A drive motor 12 is fixedly mounted on the upper outer wall of the front mounting frame 2. A first synchronous pulley 13 is fixedly mounted on the upper drive shaft of the drive motor 12. A second synchronous pulley 24 is connected to the outer end of the first synchronous pulley 13 via a synchronous belt. A transmission screw 14 is fixedly mounted in the middle of the second synchronous pulley 24. The transmission screw 14 is rotatably connected to the front outer wall of the front mounting frame 2 via a bearing seat. A lifting frame 15 is connected to the lower outer curved surface of the transmission screw 14 via a screw nut. The lifting frame 15 is movably connected to the inner wall of the through slot 11. A limit slide rod 16 is movably connected to the side of the lifting frame 15 away from the transmission screw 14. The limit slide rod 16 is fixedly mounted on the front end of the front mounting frame 2. The outer side wall of the end allows the lifting frame 15 to be linearly limited by the limiting slide rod 16. The inner side of the lifting frame 15 is rotatably connected to the cleaning shaft 17 via a rotating shaft. The cleaning soft brush roller 18 is fixedly installed on the outer curved surface of the middle part of the cleaning shaft 17. The transmission gear 19 is fixedly installed on the outer curved surface of the side end of the cleaning shaft 17. The transmission gear 19 is meshed with the transmission rack 20 on the inner side.

There are several nozzles 23, which are symmetrically distributed in sequence with respect to the lower end of the connecting water pipe 22.

[0026] Working Principle: In operation, this invention utilizes two independent yet cooperative heat dissipation circulation systems: a first condenser 6 and a second condenser 7. The first condenser 6 uses traditional refrigerant as the heat dissipation medium, while the second condenser 7 introduces coolant as the heat dissipation medium. When the automotive air conditioning system is running, the high-temperature, high-pressure refrigerant gas first enters the first condenser 6. Within the first condenser 6, the refrigerant exchanges heat with the pipe wall and heat sink 10, transferring heat to these components. Simultaneously, the coolant in the second condenser 7 circulates, absorbing heat from the refrigerant through the pipe wall of the first condenser 6, thus raising its own temperature. Due to the coolant's high specific heat capacity, it can absorb a large amount of heat. Furthermore, during circulation, it undergoes secondary heat exchange with the outside air, efficiently dissipating the absorbed heat into the atmosphere. This dual-medium synergistic heat dissipation method significantly improves heat dissipation efficiency, providing a strong guarantee for the efficient operation of the air conditioning system.

[0027] When the car is in motion, the filter 21 filters the air entering the main frame 1, preventing external impurities from entering and contaminating the first condenser pipe 6, the second condenser pipe 7, and the heat sink 10, thus affecting their heat dissipation. Simultaneously, the drive motor 12 is activated. When the drive motor 12 is activated, it drives the first synchronous pulley 13 to rotate. The rotation of the first synchronous pulley 13 drives the second synchronous pulley 24 to rotate via a synchronous belt. The rotation of the second synchronous pulley 24 drives the transmission screw 14 to rotate. The rotation of the transmission screw 14 drives the lifting frame 15 to move vertically in a linear motion via a screw nut. The vertical movement of the lifting frame 15 carries... The cleaning shaft 17 moves vertically up and down. When the cleaning shaft 17 moves vertically up and down, it drives the transmission gear 19 to move vertically up and down. When the transmission gear 19 moves vertically up and down, the force generated by the meshing connection between the transmission gear 19 and the transmission rack 20 drives the cleaning shaft 17 to rotate. When the cleaning shaft 17 rotates, it drives the cleaning soft brush roller 18 to rotate. When the cleaning soft brush roller 18 rotates, it cleans the front end of the filter screen 21 from top to bottom. At the same time, the nozzle 23 is turned on. When the nozzle 23 is turned on, it works with the cleaning soft brush roller 18 to clean the front end of the filter screen 21. This achieves the filtration of the air entering the main frame 1 while facilitating the cleaning and maintenance of the front end of the filter screen 21.
