Description
Technical Field
[0001] This utility model relates to the field of automotive equipment technology, specifically to a dustproof automotive air conditioning heat exchanger. Background Technology
[0002] The automotive air conditioning heat exchanger is a key component of the automotive air conditioning system, mainly consisting of a condenser and an evaporator. They work together to achieve the cooling and heating functions inside the vehicle. There are various types of automotive air conditioning heat exchangers to suit the needs of different vehicle models and air conditioning systems. Common types include: tube-and-fin heat exchangers, tube-and-strip heat exchangers, etc.
[0003] In automotive air conditioning systems, heat exchangers play a crucial role, and their stable and efficient performance directly impacts passenger comfort. However, traditional automotive air conditioning heat exchangers face numerous problems in practical applications. During vehicle operation, the external environment is complex and constantly changing, with the air containing a large amount of dust particles. This dust easily enters the air conditioning heat exchanger. Over time, dust gradually accumulates on the surface of the heat exchanger. On one hand, accumulated dust hinders the normal flow of air through the heat exchanger, reducing the heat exchange efficiency between the air and the internal medium, significantly diminishing the cooling or heating effect of the air conditioning. Furthermore, long-term dust adhesion to the heat exchanger surface can also cause corrosion and other problems, shortening the heat exchanger's lifespan and increasing vehicle maintenance costs and frequency. Utility Model Content
[0004] The purpose of this utility model is to provide a dustproof automotive air conditioning heat exchanger, thereby facilitating dust prevention of the heat exchanger.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0029] Example 1:
[0030] A preferred embodiment of the dustproof automotive air conditioning heat exchanger provided by this utility model is as follows: Figure 1-4The image shows a dustproof automotive air conditioning heat exchanger, comprising a housing 1, a controller 3 mounted on the top of the housing 1, a door 2 bolted to one side of the housing 1, and a heat exchange assembly 4 disposed inside the housing 1. The heat exchange assembly 4 includes: a dustproof component 41 disposed on the front of the housing 1; and a heat exchange component 42 disposed inside the housing 1. The dustproof component 41 includes: a connecting frame 411 disposed on the front of the housing 1; a baffle 412 fixedly installed in the middle of the connecting frame 411; a mounting frame 414 fixedly installed inside the connecting frame 411; and a protective frame 416. The connecting frame 411 is connected to both sides of the connecting frame 411. A dust outlet is provided on the surface of the baffle 412. A guide plate 413 is fixedly installed on one side of the inner wall of the baffle 412. An air inlet is provided on the front of the connecting frame 411. Air outlets are equidistantly provided on the front of the connecting frame 411. A connection port is provided on the front of the connecting frame 411. The air outlet is located directly below the air inlet. The connection port is located between the air inlet and the air outlet. A locking rod 4115 is fixedly installed on both sides of the inner wall of the connecting frame 411. A limit plate 4116 is fixedly installed at one end of the locking rod 4115. A receiving box 4117 is snap-fitted onto the outer wall. The top of the receiving box 4117 is connected to the dust outlet of the baffle 412. A locking plate 4118 is fixedly installed on the front of the receiving box 4117. The locking plate 4118 is snap-fitted onto the connecting frame 411 through a connecting port. A handle 4119 is fixedly installed on the front of the locking plate 4118. A dustproof net 415 is installed inside the mounting frame 414. A motor 417 is fixedly installed at the bottom of the protective frame 416. A threaded rod 418 is provided at the output end of the motor 417. The top of the threaded rod 418 moves through the outer wall of the protective frame 416. The bottom of the protective frame 416 extends to the top of the inner wall of the protective frame 416 and is rotatably connected to the protective frame 416 via a bearing. The outer wall of the threaded rod 418 is threadedly connected to a movable block 419. A guide rod 4111 is fixedly installed inside another protective frame 416. A movable block 4112 is slidably sleeved on the outer wall of the guide rod 4111. A connecting plate 4113 is fixedly installed between the movable block 4112 and the movable block 419. A cleaning brush 4114 is fixedly installed on the inner side of the connecting plate 4113. The cleaning brush 4114 is in contact with the dustproof net 415.
[0031] Furthermore, in this embodiment, by allowing outside air to enter through the air inlet of the connecting frame 411, the air first passes through the dustproof net 415 inside the mounting frame 414. The dustproof net 415 can block most dust particles, thus initially purifying the air. When it is necessary to clean the dustproof net 415, the motor 417 at the bottom of the protective frame 416 starts, driving the threaded rod 418 to rotate. Since the movable block 419 is threadedly connected to the threaded rod 418, the guide rod 4111 guides the movable block 4112. When in use, movable block 1 419 and movable block 2 4112 will move along threaded rod 418 and guide rod 4111, thereby driving connecting plate 4113 and its cleaning brush 4114 to move on the surface of dustproof net 415, brushing off the dust on dustproof net 415. The brushed-off dust will fall into receiving box 4117 through dust outlet along the guide plate 413 on the inner wall of baffle 412. Receiving box 4117 can be disassembled and cleaned through the connection port between locking plate 4118 and connecting frame 411.
[0032] Example 2:
[0033] Based on Embodiment 1, a preferred embodiment of the dustproof automotive air conditioning heat exchanger provided by this utility model is as follows: Figure 1-4 As shown: The heat exchange component 42 includes: a partition plate 421, fixedly installed inside the housing 1; an upper air guide plate 422, fixedly installed inside the housing 1; a lower air guide plate 423, fixedly installed inside the housing 1; and a liquid storage tank 424, fixedly installed inside the housing 1. The lower air guide plate 423 is located directly below the upper air guide plate 422. A mounting rod 4211 is fixedly installed on one side of the partition plate 421. Heat dissipation fins 4216 are equidistantly sleeved on the outer wall of the mounting rod 4211. Spacers 4212 are arranged between the heat dissipation fins 4216 and are sleeved on the outer wall of the mounting rod 4211. A nut 4213 is threadedly connected to the other end of the mounting rod 4211. The inner surface of the heat dissipation fins 4216... The housing is equipped with a circulation pipe 4214. Both ends of the circulation pipe 4214 pass through one side of the partition 421 and extend to the other side of the partition 421. One end of the circulation pipe 4214 is connected to the liquid storage tank 424, and the other end of the circulation pipe 4214 passes through the outside of the liquid storage tank 424 and extends to the inside of the liquid storage tank 424. A water pump 4215 is connected to the liquid storage tank 424. A heating plate 425, a semiconductor condenser 426, and a temperature sensing module 427 are respectively provided on the side of the liquid storage tank 424 near the partition 421. A connecting pipe 428 is connected to the other side of the liquid storage tank 424. The other end of the connecting pipe 428 passes through the inner wall of the housing 1 and extends to the outer wall of the housing 1. An electric valve 429 is provided therein.
[0034] Furthermore, in this embodiment, the air, after being treated to prevent dust, enters the heat exchange area inside the housing 1 through the upper air guide plate 422. When cooling is required, the temperature sensing module 427 detects a temperature signal. If the temperature is high, the semiconductor condenser 426 operates, lowering the temperature of the refrigerant in the circulation pipe 4214. The water pump 4215 starts, causing the refrigerant in the liquid storage tank 424 to circulate in the circulation pipe 4214. When the air passes through the heat dissipation fins 4216 on the mounting rod 4211, the heat is absorbed by the low-temperature refrigerant in the circulation pipe 4214, lowering the air temperature and achieving cooling. The lower air guide plate 423 guides the air to flow reasonably in the heat exchange area, making the heat exchange more complete. When heating is required, the heating plate 425 works to heat the medium such as antifreeze in the circulation pipe 4214. Similarly, under the action of the water pump 4215, the hot medium circulates in the circulation pipe 4214. When the air passes through the heat dissipation fins 4216, it absorbs heat and its temperature rises, achieving the heating effect. The medium in the circulation pipe 4214 circulates between the liquid storage tank 424 and the circulation pipe 4214. The connecting pipe 428 and the electric valve 429 can perform operations such as replenishing or discharging the medium when needed to maintain the normal operation of the system.
[0035] In use, outside air enters through the air inlet of the connecting frame 411. First, the air passes through the dust filter 415 inside the mounting frame 414. The dust filter 415 can block most dust particles, initially purifying the air. When it is necessary to clean the dust filter 415, the motor 417 at the bottom of the protective frame 416 starts, driving the threaded rod 418 to rotate. Since the movable block 419 is threadedly connected to the threaded rod 418, under the guidance of the guide rod 4111 on the movable block 4112, the movable block 419 and the movable block 4112 will move along the threaded rod 418 and the guide rod 4111, thereby driving the connecting plate 4113 and its cleaning brush. 4114 moves on the surface of the dustproof net 415, brushing off the dust on the dustproof net 415. The brushed-off dust will fall into the receiving box 4117 through the dust outlet along the guide plate 413 on the inner wall of the baffle 412. The receiving box 4117 can be disassembled and cleaned through the connection port between the snap-fit plate 4118 and the connecting frame 411. After the dustproof treatment, the air enters the heat exchange area inside the housing 1 through the upper air guide plate 422. When cooling is required, the temperature sensing module 427 detects the temperature signal. If the temperature is high, the semiconductor condenser 426 works, which lowers the temperature of the refrigerant in the circulation pipe 4214. The water pump 4215 starts, which lowers the temperature of the refrigerant in the liquid storage tank 424. The refrigerant circulates in the circulation pipe 4214. When air passes through the heat dissipation fins 4216 on the mounting rod 4211, heat is absorbed by the low-temperature refrigerant in the circulation pipe 4214, lowering the air temperature and achieving cooling. The upper air guide plate 422 and the lower air guide plate 423 guide the air to flow reasonably in the heat exchange area, making heat exchange more complete. When heating is needed, the heating plate 425 works, heating the medium such as antifreeze in the circulation pipe 4214. Similarly, under the action of the water pump 4215, the hot medium circulates in the circulation pipe 4214. When air passes through the heat dissipation fins 4216, it absorbs heat, raising its temperature and achieving a heating effect. The medium circulates between the storage tank 424 and the circulation pipe 4214. The connecting pipe 428 and the electric valve 429 can perform operations such as replenishing or discharging the medium when needed to maintain the normal operation of the system. The controller 3 receives signals from sensors such as the temperature sensing module 427 and controls the working status of components such as the semiconductor condenser 426, heating plate 425, water pump 4215, motor 417 and electric valve 429 according to the preset program to realize the automated operation and precise control of the entire automotive air conditioning heat exchanger, so as to meet different temperature requirements in the car, ensure the stable operation and efficient heat exchange of the system, and maintain the effective operation of the dustproof function.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
