Description

Technical Field

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

[0002] As a core component of the automotive air conditioning system, the evaporator plays a crucial role in converting liquid refrigerant into gaseous refrigerant and absorbing heat from the vehicle's interior during this process, thereby achieving cooling. Traditional automotive air conditioning evaporators typically consist of a series of parallel refrigerant pipes and heat dissipation fins. The liquid refrigerant flows within the pipes, absorbing heat transferred through the fins and evaporating. Simultaneously, air from inside the vehicle is forced through the gaps between the fins, exchanging heat with the fins and pipe surfaces, thus achieving cooling and dehumidification. Existing evaporators have certain drawbacks. For example, Chinese patent CN222165231 U discloses an anti-frost automotive air conditioning evaporator, which includes an air conditioning evaporator body, an evaporator pipe inside the evaporator body, a coil inside the air conditioning evaporator body, an evaporator shell evenly distributed inside the air conditioning evaporator body, an evaporator shell fixedly connected to the outer surface of the evaporator pipe, an expansion valve installed on one end of the evaporator pipe, a main drainage groove evenly distributed on the outer surface of the evaporator shell, a drainage and leak-proof component installed on the outer surface of the evaporator shell, and an accelerated anti-frost component installed on the outer surface of the evaporator shell. Although this device can cool, it lacks a structure to guide the orderly flow of airflow. When the airflow blows towards the evaporator, it spreads in all directions, causing disordered flow of cold air and reducing cooling efficiency. Furthermore, the airflow generating structure of this device is inconvenient to disassemble, requiring the removal of many fixed structures during later maintenance and replacement.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 As shown, this utility model provides the following technical solution:

[0027] An evaporator for automotive air conditioning includes an air guide 1. One side of the air guide 1 is open to form an air guide cavity 12, and the other side is open to form a first air inlet 111. The first air inlet 111 is connected to the air guide cavity 12. An evaporator 2 is installed inside the air guide cavity 12. An air blowing component 3 is installed on one side of the air guide 1. The air blowing component 3 is located on one side of the first air inlet 111, and an air guide channel is formed between the air blowing component 3, the first air inlet 111, and the air guide cavity 12 to guide the flow of gas along a preset path. The evaporator 2 is located on the air guide channel.

[0028] With the above technical solution, when personnel need to install the device, the air guide 1 is fixed at the position where the vehicle needs to be installed, the air blowing component 3 is installed on one side of the first air inlet 111, and the evaporator 2 is fixed in the air guide cavity 12 inside the air guide 1. The air blowing component 3 generates airflow and guides the airflow to the first air inlet 111. The airflow is blown into the air guide cavity 12 inside the air guide 1 through the first air inlet 111. The evaporator 2 cools the airflow, thereby lowering the temperature around it. When the airflow enters the air guide cavity 12, the airflow temperature is lowered, and finally it is discharged through the opening of the air guide cavity 12, thereby blowing the cold airflow in front of the air guide cavity 12 and allowing the cold airflow to flow in an orderly manner.

[0029] To facilitate the replacement of the air blowing component 3, such as Figures 1-2 , Figures 4-7 As shown, the top and bottom of the air guide cover 11 are fixedly connected to the card plate 17, and the top and bottom of the air blowing component 3 are fixedly connected to the card rod 32. The card plate 17 has a card groove 19, and one side of the card plate 17 is open to form an inclined groove 18. The inclined groove 18 gradually widens from the side near the card groove 19 to the other side, and the card rod 32 matches the card groove 19. The top and bottom of the card groove 19 are fixedly connected to the limiting protrusion 110, and the peripheral surface of the card rod 32 has a limiting groove 33 that matches the limiting protrusion 110.

[0030] In this embodiment, when personnel need to install the device, the air guide 1 is fixed at the desired installation location on the vehicle. Then, the air blower 3 is installed to one side of the first air inlet 111, causing the locking rod 32 on the air blower 3 to engage with the inclined groove 18 on one side of the clamping plate 17. Pushing the air blower 3 causes the locking rod 32 on the air blower 3 to engage with the groove 19 inside the clamping plate 17. The limiting protrusion 110 on the inner wall of the groove 19 engages with the limiting groove 33 on the locking rod 32, thereby fixing the air blower 3 to one side of the first air inlet 111. Finally, the evaporator 2 is fixed in the air guide cavity 12 inside the air guide 1. Airflow is generated by the air blowing component 3 and guided to the first air inlet 111. The airflow is then blown into the air guiding chamber 12 inside the air blowing component 1 through the first air inlet 111. The airflow is cooled by the evaporator 2, thereby lowering the temperature of its surroundings. When the airflow enters the air guiding chamber 12, the airflow temperature is lowered, and finally it is discharged through the opening of the air guiding chamber 12, thus blowing the cold airflow in front of the air guiding chamber 12 and allowing the cold airflow to flow in an orderly manner. When personnel need to disassemble the air blowing component 3, they pull the air blowing component 3 to move it laterally, thereby separating the clamp 32 from the clamp plate 17, so that the air blowing component 3 can be removed for replacement or repair.

[0031] Specifically, in one embodiment, regarding the aforementioned air blowing element 3:

[0032] like Figure 2 , Figure 6 As shown, the air blowing component 3 includes a mounting plate 31, on which a through-type second air inlet 38 is provided, and a fan 39 is installed inside the second air inlet 38.

[0033] In this embodiment, the mounting plate 31 is installed on one side of the first air inlet 111, so that the locking rod 32 on the mounting plate 31 engages with the inclined groove 18 on one side of the locking plate 17. The mounting plate 31 is pushed so that the locking rod 32 on the mounting plate 31 engages with the locking groove 19 inside the locking plate 17. The limiting protrusion 110 on the inner wall of the locking groove 19 engages with the limiting groove 33 on the locking rod 32, thereby fixing the mounting plate 31 to one side of the first air inlet 111. The fan 39 works to guide the airflow, so that the airflow is blown into the first air inlet 111 through the second air inlet 38.

[0034] Furthermore, when fan 39 guides the gas flow, in order to filter the gas, such as... Figure 6 As shown, two brackets 34 are symmetrically fixedly connected to the side of the mounting plate 31 away from the air guide 1. A detachable baffle 35 is installed between the two brackets 34, and a dustproof net 36 is installed on the baffle 35.

[0035] In this embodiment, the baffle 35 is installed between the two brackets 34, and the dust filter 36 is installed on one side of the mounting plate 31. When the fan 39 guides the airflow, the dust filter 36 filters the gas, thereby removing dust from the gas.

[0036] Furthermore, in this utility model, regarding the aforementioned air guide 1, as follows: Figures 1-2 , Figures 4-5 As shown, the air guide 1 includes an air guide cover 11, an air guide cavity 12 formed on one side of the air guide cover 11, and a first air inlet 111 formed on the other side of the air guide cover 11.

[0037] In this embodiment, the evaporator 2 is installed in the air guide cavity 12 inside the air guide cover 11. The fan 39 operates so that the fan 39 guides the external airflow into the air guide cavity 12, thereby blowing the cold airflow near the evaporator 2 to the outside.

[0038] Furthermore, when personnel need to pull the baffle 35, in order to make the baffle 35 easy to pull, such as Figure 6 As shown, the top of the baffle 35 is recessed to form a groove 37. When a person needs to pull the baffle 35, the groove 37 helps to make the baffle 35 easy to pull.

[0039] In addition, in this utility model, when personnel need to fix the air guide cover 11, in order to make the air guide cover 11 easy to fix, such as Figures 1-2 , Figures 4-5 As shown, a side plate 13 is fixedly connected to the outside of the air guide shroud 11, and a screw 14 is screwed onto the side plate 13.

[0040] In this embodiment, the air guide shroud 11 is aligned with the position to be fixed, and the side plate 13 on the air guide shroud 11 is aligned with the position to be fixed. The screw 14 on the side plate 13 is rotated so that the screw 14 enters into another object. The air guide shroud 11 is fixed by the screw 14 contacting the side plate 13.

[0041] Furthermore, in this utility model, an expansion valve 15 is provided on the side of the air guide shroud 11 adjacent to the side plate 13. A connecting pipe 16 is fixedly connected to the expansion valve 15. One end of the connecting pipe 16 extends into the air guide cavity 12 and communicates with the evaporator 2. The expansion valve 15 connects to the pipeline that delivers refrigerant, and the connecting pipe 16 cooperates with the evaporator 2 to allow the evaporator 2 to cool down, thereby reducing the temperature near the evaporator 2 itself.

[0042] Specifically, in one embodiment, regarding the evaporator 2 described above, as... Figures 1-3 As shown, the evaporator 2 includes an evaporator tube 21, and multiple heat dissipation plates 22 are fitted on the evaporator tube 21.

[0043] In this embodiment, when the refrigerant is introduced into the evaporator tube 21, the temperature of the vicinity is reduced by the cooperation of the evaporator tube 21 and the heat sink 22.

[0044] When condensate forms inside the device, in order to guide the flow of the condensate, such as... Figure 4As shown, a guide slope is formed on the inner wall of the air guide cavity 12 near the first air inlet 111, and the horizontal height of the guide slope near the first air inlet 111 is higher than the horizontal height of the other side.

[0045] In this embodiment, when condensate is generated on the evaporator tube 21 and the heat sink 22, the water flow is guided by the flow guide ramp to prevent the condensate from flowing towards the fan 39.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
