Description

Technical Field

[0001] This utility model belongs to the technical field of automotive air conditioning, specifically a protective evaporator for automotive air conditioning. Background Technology

[0002] As a core heat exchange component of the automotive air conditioning system, the evaporator's main function is to cool the hot air flowing through the fins of the vehicle interior by absorbing heat through the vaporization of refrigerant inside the copper tubes, thereby achieving temperature reduction inside the vehicle. Currently, most mainstream automotive air conditioning evaporators adopt a tube-fin structure of "copper tube-aluminum fins," using a mechanical tube expansion process to ensure a tight fit between the copper tubes and fins, thus guaranteeing efficient heat transfer.

[0003] However, most mainstream automotive air conditioning evaporators currently use a tube-fin structure with copper tubes and aluminum fins. During use, condensate easily adheres to the fin surface, lacking good airflow guidance. This not only causes corrosion on the fin surface but also occupies space on the fin surface, thus affecting heat exchange efficiency. Furthermore, the airflow directly enters and contacts the fins and copper tubes without good airflow guidance, which cannot guarantee that the fins can contact the air evenly. Some air bypasses the fin group directly and is discharged without participating in heat exchange, resulting in a waste of the electrical energy consumed by the fan and also affecting heat exchange efficiency. Utility Model Content

[0004] This utility model provides a protective automotive air conditioning evaporator, which can effectively solve the problem that existing automotive air conditioning evaporators lack good airflow and ventilation measures, resulting in generally low heat exchange efficiency. An automotive protective air conditioning evaporator includes an outer frame, inside which are installed a plurality of parallel fins, and through which are installed copper coils for medium transport. An air guide mechanism is fixedly installed at the front of the outer frame, and a water collection tank for condensate discharge is installed at the bottom inner side of the outer frame.

[0005] As a further technical solution of this utility model, one end of the copper coil passes through one side of the outer frame, and the other end of the copper coil passes through the other side of the outer frame.

[0006] As a further technical solution of this utility model, the air guiding mechanism includes a connecting plate, a plurality of guide grooves are provided through the connecting plate, and a connecting frame is fixedly connected to one side of the connecting plate. A cover is fixedly connected to the side of the connecting frame away from the guide grooves, and an exhaust fan is fixedly installed on the side of the cover away from the connecting frame. An inclined guide surface is provided on the side of the fins facing the guide grooves.

[0007] As a further technical solution of this utility model, the connecting plate is fixedly connected to the outer frame, and the lateral distance of the guide groove is adapted to the lateral spacing of the adjacent fins.

[0008] As a further technical solution of this utility model, the two sides of the cover are inclined, and the length and width of the side closest to the connecting frame are the same as the length and width of the connecting frame.

[0009] As a further technical solution of this utility model, an installation groove is provided on the outermost side of the cover, and the induced draft fan is fixedly installed in the installation groove.

[0010] As a further technical solution of this utility model, a number of fixing grooves for fixing copper coils are opened at the center line positions on both sides of the fin, and guide sleeves are fixedly installed in the fixing grooves.

[0011] As a further technical solution of this utility model, the fins are provided with flow guide grooves on both sides near the guide sleeve, and several support grooves are provided on the side of the flow guide grooves. Two baffles and baffles are installed inside the water collection tank. Baffles are located between the two baffles. A drainage groove is provided in the area between baffles and baffles in the water collection tank.

[0012] As a further technical solution of this utility model, the guide channel is arranged vertically and the support channel is arranged obliquely upward.

[0013] As a further technical solution of this utility model, the bottom of the guide channel is connected to the area between baffle one and baffle two.

[0014] The beneficial effects of this utility model are as follows: By setting up an air guide mechanism, this utility model can achieve precise air guidance. Because the guide groove is adapted to the gap between adjacent fins and an inclined guide surface is set on the fins, the airflow can accurately enter between adjacent fins and make uniform contact with the fins to achieve heat exchange, thereby effectively increasing the heat exchange effect of the air conditioner evaporator and reducing the occurrence of some air directly bypassing the fins and being discharged. Meanwhile, a guide channel is set up in conjunction with a support channel. The support channel is aligned with the airflow direction, which can accelerate the condensate to enter the guide channel quickly. Under the guidance of the guide channel, the condensate enters the water collection tank and enters the area formed by baffle one and baffle two. Then it is discharged from the drain channel, which effectively reduces the adhesion of condensate on the fin surface and avoids condensate from corroding the fins or occupying the fin surface space and affecting the heat exchange efficiency.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-4 As shown, an automotive protective air conditioning evaporator includes an outer frame 1. Several parallel fins 3 are installed inside the outer frame 1, and copper coils 4 for medium transportation are installed through the fins 3. An air guide mechanism 2 is fixedly installed at the front of the outer frame 1, and a water collection tank 5 for condensate drainage is installed at the bottom inner side of the outer frame 1. The condensate generated by the fins 3 during operation is eventually collected by the water collection tank 5, thus facilitating its discharge.

[0020] One end of the copper coil 4 passes through one side of the outer frame 1, and the other end of the copper coil 4 passes through the other side of the outer frame 1.

[0021] The air guiding mechanism 2 includes a connecting plate 21, through which a plurality of guide slots 25 are provided. A connecting frame 22 is fixedly connected to one side of the connecting plate 21. A cover 23 is fixedly connected to the side of the connecting frame 22 away from the guide slots 25. An induced draft fan 24 is fixedly installed on the side of the cover 23 away from the connecting frame 22. An inclined guide surface 10 is provided on the side of the fins 3 facing the guide slots 25.

[0022] The air introduced by the induced draft fan 24 is precisely guided by the air guide mechanism 2, so that the air can accurately enter the gap between adjacent fins 3, thereby making precise contact with the fins 3 and improving the heat exchange effect.

[0023] The connecting plate 21 is fixedly connected to the outer frame 1, and the lateral distance of the guide groove 25 is adapted to the lateral spacing of the adjacent fins 3.

[0024] The two sides of the cover 23 are inclined, and the length and width of the side closest to the connecting frame 22 are the same as the length and width of the connecting frame 22. The outermost side of the cover 23 has a mounting groove, and the induced draft fan 24 is fixedly installed in the mounting groove.

[0025] Several fixing grooves 8 are provided on both sides of the center line of the penetrating fin 3 for fixing the copper coil 4, and guide sleeves 9 are fixedly installed in the fixing grooves 8. The guide sleeves 9 facilitate the fixing of the copper coil 4 without affecting the heat conduction of the copper coil 4.

[0026] Both sides of the fin 3 are provided with flow guide grooves 6 near the guide sleeve 9. Several support grooves 7 are provided on the side of the flow guide grooves 6. Two baffles 1 51 and baffle 2 52 are installed inside the water collection tank 5. Baffle 2 52 is located between the two baffles 1 51. A drainage groove 53 is provided in the area between baffles 1 51 and baffle 2 52 in the water collection tank 5.

[0027] The guide channel 6 is vertically positioned, while the support channel 7 is angled upwards. This aligns with the direction of air inflow, thereby accelerating the entry of condensate into the guide channel 6.

[0028] The bottom of the guide channel 6 is connected to the area between baffle 1 51 and baffle 2 52, which facilitates the precise introduction of condensate into the water collection tank 5.

[0029] An automotive protective air conditioning evaporator, in use, air enters through the air guide mechanism 2, copper coil 4 is used for medium guidance, and heat is diffused using fins 3. The exhaust fan 24 introduces the air, first into the cover 23, then through the connecting frame 22, and into the adjacent fins 3 through each guide groove 25. The windward side of the fins 3 is provided with an inclined guide surface 10 to introduce the air force again, achieving precise guidance. Thus, the airflow can evenly cover both sides of each fin 3, achieving precise heat exchange and increasing the heat exchange area of ​​the fins 3.

[0030] As the airflow enters, the condensate formed on the surface of the fin 3 flows into each support groove 7, then into the guide groove 6, and is discharged downward along the guide groove 6 into the water collection tank 5, entering the area formed by baffle 1 51 and baffle 2 52, and then discharged from the drain groove 53, effectively reducing the adhesion of condensate on the surface of the fin 3 and effectively protecting the fin 3.
