Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an air conditioning unit with optimized air mixing ratio and temperature damper based on door stop cooperation, and an air conditioning unit. Background Technology

[0002] Vehicle air conditioning units typically have cold and hot aisles. Airflow of different volumes mixes in these aisles before being delivered into the vehicle cabin. A temperature damper is a type of damper that adjusts the airflow ratio between the cold and hot aisles (the ratio of the airflow entering the hot aisle to the total airflow is called the mixing ratio). Its operation involves the temperature damper moving from a fully cold position (defined as 0%) to a fully hot position (defined as 100%) or vice versa. Some air conditioning unit designs exhibit a faster initial increase in the mixing ratio, but considering comfort and energy efficiency, the required initial increase in the mixing ratio is usually slower. Traditional methods for optimizing the initial mixing ratio involve increasing the resistance of the hot aisle; however, increasing the resistance reduces the maximum airflow in hot mode, affecting the heating performance of the air conditioning unit.

[0003] Therefore, there is an urgent need for a temperature damper based on door stop coordination to optimize the air mixing ratio of the air handling unit, in order to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a temperature damper for air conditioning unit with optimized air mixing ratio based on door stop cooperation, which can significantly reduce the front-end air mixing ratio without losing the maximum air volume in hot mode.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0006] A temperature damper for optimizing the air mixing ratio of an air conditioning unit based on door stop cooperation is provided, including:

[0007] A door stop is installed at the air intake duct of the air conditioning unit. The air intake duct includes a cold aisle and a hot aisle. The door stop includes a first door stop, a second door stop, and a third door stop. The cold aisle is located between the first door stop and the third door stop, and the hot aisle is located between the third door stop and the second door stop.

[0008] A temperature damper is slidably disposed at the air inlet channel. The temperature damper includes a damper body and a baffle. The baffle is connected to the end of the damper body near the second door stop in the direction of movement of the temperature damper. The length of the baffle in the direction perpendicular to the movement of the temperature damper is the same as the length of the damper body. When the temperature damper leaves the fully cold position, the baffle is used to reduce the gap between the temperature damper and the inner wall of the hot channel. When the temperature damper moves to the fully hot position, the projection of the third door stop in the thickness direction of the temperature damper covers the baffle.

[0009] The temperature damper has a first end and a second end opposite to each other in the direction of movement of the temperature damper. When the temperature damper moves to the full heat position, the first end is sealed against the first door stop and the second end is sealed against the third door stop. When the temperature damper moves to the full cold position, the first end is sealed against the third door stop and the second end is sealed against the second door stop.

[0010] Optionally, the first end includes a first side and a first seal, the first seal being in sealing contact with the first door stop or the third door stop;

[0011] The second end includes a second side and a second seal, the baffle is connected to the second side, and the second seal is in sealing contact with the third door stop or the second door stop.

[0012] Optionally, the baffle is connected to the second side and extends along the plane of the second side.

[0013] Optionally, the baffle is connected to the second side, the baffle is inclined toward the side closer to the second seal, and the baffle is set at an angle to the plane where the second side is located, so as to reduce the gap between the baffle and the inner wall of the hot channel when the temperature damper is in the preset position.

[0014] Optionally, the first door stop has a first slot, the first end is inserted into the first slot, and the first seal is in sealing contact with the inner wall of the first slot.

[0015] Optionally, the second door stop has a second slot, the second end is inserted into the second slot, and the second seal is in sealing contact with the inner wall of the second slot.

[0016] Optionally, the third door stop has an abutment plane near the side of the temperature damper, and the first seal or the second seal seals in sealing contact with the abutment plane.

[0017] Optionally, the first seal is bent toward the side opposite to the first side;

[0018] The second seal is bent toward the side opposite to the second side.

[0019] Optionally, the temperature damper and the baffle are integrally formed.

[0020] Another objective of this invention is to provide an air conditioning unit that can significantly reduce the front-end air mixing ratio and improve the performance of the air conditioning unit without sacrificing the maximum air volume in hot mode.

[0021] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0022] An air conditioning unit is provided, including an air conditioning unit housing, a damper drive structure, and the aforementioned air conditioning unit air-mixing ratio optimized temperature damper based on door stop cooperation. The temperature damper and the damper drive structure are both disposed inside the air conditioning unit housing and located at the air inlet channel. The damper drive structure is used to drive the temperature damper to move along a preset trajectory to switch between a full cooling position and a full heating position.

[0023] The beneficial effects of this utility model are as follows:

[0024] This invention proposes an optimized temperature damper for air conditioning unit air mixing ratio based on door stop cooperation. It includes a door stop and a temperature damper. The door stop is located at the air inlet channel of the air conditioning unit, which includes a cold channel and a hot channel. The temperature damper is slidably disposed at the air inlet channel. The temperature damper has a first end and a second end opposite to each other in the direction of movement. When the temperature damper moves to the fully hot position, the first end seals against the first door stop and the second end seals against the third door stop. When the temperature damper moves to the fully cold position, the first end seals against the third door stop and the second end seals against the second door stop. The temperature damper includes a damper body and a baffle. The baffle is connected to the end of the damper body near the second door stop in the direction of movement of the temperature damper, and its length in the plane of the temperature damper is the same as the length of the damper body in the direction perpendicular to the movement of the temperature damper. When the temperature damper leaves the fully cold position, the baffle reduces the gap between the temperature damper and the inner wall of the hot channel. As the temperature damper moves from the fully cold position towards the fully hot position, adding a baffle can, compared to the damper itself, block more of the flow area of ​​the hot passage, thus reducing the gas flow rate within the hot passage. As the temperature damper gradually moves towards the fully hot position, the flow area of ​​the hot passage continuously increases, and the proportion of the flow area of ​​the hot passage blocked by the baffle to the open flow area gradually decreases. The baffle's effect on reducing the air-to-mixing ratio weakens. Therefore, the baffle's effect on reducing the air-to-mixing ratio is only significant in the initial stage of the temperature damper's movement, which perfectly matches the air-to-mixing ratio requirement of the air conditioning unit—that is, the air-to-mixing ratio increases slowly in the initial stage. Furthermore, when the temperature damper moves to the fully hot position, the projection of the third door baffle along the thickness direction of the temperature damper covers the baffle, meaning that the baffle's size is limited so that it does not block the hot passage when the temperature damper is in the fully hot position, thus not sacrificing the maximum airflow in the hot mode.

[0025] The air conditioning unit proposed in this utility model includes an air conditioning unit shell, a damper drive structure, and the aforementioned temperature damper for optimizing the air-to-air ratio based on door stop cooperation. Both the temperature damper and the damper drive structure are disposed within the air conditioning unit shell and located at the air inlet channel. The damper drive structure drives the temperature damper to move along a preset trajectory to switch between a fully cooling position and a fully heating position. The temperature damper in this air conditioning unit can significantly reduce the front-end air-to-air ratio without sacrificing the maximum airflow in hot mode, thereby improving the performance of the air conditioning unit.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] The temperature damper 4 of the air conditioning unit 100 is slidably installed at the air inlet channel. When the temperature damper 4 closes the hot channel 1002, the gas can only pass through the cold channel 1001. When the temperature damper 4 closes the cold channel 1001, the gas can only pass through the hot channel 1002. When part of the temperature damper 4 is located in the hot channel 1002 and the other part is located in the cold channel 1001, some gas passes through the cold channel 1001 and some gas passes through the hot channel 1002. The gas flow rate is different depending on the flow area of ​​the cold channel 1001 and the hot channel 1002, and the air mixing ratio is different. The temperature damper 4 is the damper that adjusts the gas flow ratio in the cold channel 1001 and the hot channel 1002.

[0044] This embodiment provides a temperature damper for optimizing the air-mixing ratio of an air conditioning unit based on door stop cooperation. It includes a door stop and a temperature damper 4. The door stop is disposed at the air inlet channel of the air conditioning unit 100, which includes a cold channel 1001 and a hot channel 1002. The temperature damper 4 is slidably disposed at the air inlet channel. The temperature damper 4 has a first end and a second end opposite to each other in its moving direction. When the temperature damper 4 moves to the fully hot position, the first end seals against the first door stop 1 and the second end seals against the third door stop 3. When the temperature damper 4 moves to the fully cold position, the first end seals against the third door stop 3 and the second end seals against the second door stop 2. In this embodiment, the temperature damper 4 includes a damper body 41 and a baffle 42. The baffle 42 is connected to the end of the damper body 41 near the second door stop 2 in the moving direction of the temperature damper 4. In the plane of the temperature damper 4, the length of the baffle 42 in the direction perpendicular to the moving direction of the temperature damper 4 is the same as the length of the damper body 41.

[0045] When the temperature damper 4 leaves the fully cooled position, the baffle 42 is used to reduce the gap between the temperature damper 4 and the inner wall of the hot channel 1002. For example... Figures 1 to 4 As shown, when the temperature damper 4 moves from the fully cold position to the fully hot position, the addition of baffle 42, compared to the damper body 41 alone, can block more of the flow area of ​​the hot channel 1002, thereby reducing the gas flow rate in the hot channel 1002. As the temperature damper 4 gradually moves towards the fully hot position, the flow area of ​​the hot channel 1002 continuously increases. The proportion of the flow area of ​​the hot channel 1002 blocked by baffle 42 to the flow area of ​​the already open hot channel 1002 gradually decreases, and the effect of baffle 42 on reducing the air-mixing ratio weakens. It can be seen that the setting of baffle 42 only has a significant effect on reducing the air-mixing ratio in the initial stage of the temperature damper 4's movement. This is exactly in line with the air-mixing ratio requirement of the air conditioning unit 100, that is, the air-mixing ratio rises slowly in the initial stage. As shown in the table below, based on the temperature damper 4 provided in this embodiment and the existing damper structure, the air mixing ratio at different damper positions can be compared. It can be seen that when the damper position is between 10% and 50% (the damper moves from the fully cold position to the fully hot position), the optimized air mixing ratio is lower than the original air mixing ratio. Moreover, as can be seen from the reduction ratio in the table, the front air mixing ratio is reduced more, which fully meets the actual needs.

[0046] Air damper position Original air-fuel mixture ratio (%) Optimized air-mixing ratio (%) Reduce ratio 10％ 4.3 3.3 21.8％ 20％ 16.2 9.9 38.7％ 30％ 26.1 20.8 20.6％ 40％ 35.4 32.3 9.3％ 50％ 44.4 41.4 6.9％

[0047] In addition, such as Figure 5 and Figure 6 As shown, when the temperature damper 4 moves to the full heat position, the projection of the third door stop 3 on the thickness direction of the temperature damper 4 covers the baffle 42, that is, the size of the baffle 42 is limited so that the temperature damper 4 does not block the heat channel 1002 when it is in the full heat position, and the maximum air volume of the heat mode is not lost.

[0048] Optionally, the first end includes a first side 411 and a first seal 43, the first seal 43 sealingly abutting against the first door stop 1 or the third door stop 3. The second end includes a second side 412 and a second seal 44, the baffle 42 is connected to the second side 412, and the second seal 44 sealingly abutting against the third door stop 3 or the second door stop 2. In this embodiment, the first side 411 and the second side 412 are rigid structures, and the first seal 43 and the second seal 44 are flexible structures. In the air inlet direction, the first side 411 is located upstream of the first seal 43, and the first side 411 can protect the first seal 43. The second side 412 is located upstream of the second seal 44, and the second side 412 can protect the second seal 44, thereby extending the service life of the first seal 43 and the second seal 44. In this embodiment, both the first seal 43 and the second seal 44 are soft rubber structures. When the temperature damper 4 moves to the full heat position, the first seal 43 is press-fitted with the first door stop 1, thereby sealing the first end with the first door stop 1. At this time, the second seal 44 moves to the third door stop 3, and the second seal 44 is press-fitted with the third door stop 3, thereby sealing the second end with the third door stop 3, so that the temperature damper 4 completely seals the cold passage 1001. When the temperature damper 4 moves to the full cold position, the first seal 43 is press-fitted with the third door stop 3, thereby sealing the first end with the third door stop 3. At this time, the second seal 44 moves to the second door stop 2, and the second seal 44 is press-fitted with the second door stop 2, thereby sealing the second end with the second door stop 2, so that the temperature damper 4 completely seals the hot passage 1002.

[0049] Optionally, the baffle 42 is connected to the second side 412, and the baffle 42 extends along the plane of the second side 412. In this embodiment, the damper body 41 extends in an arc shape, so the baffle 42 is also arc-shaped. The radius and curvature of the arc of the baffle 42 can be adjusted according to the size of the door stop. For example, the radius of the arc of the baffle 42 can be set to 280.85 mm, and the curvature is 0.018 rad.

[0050] Optionally, the temperature damper 4 and the baffle 42 are integrally formed. In this embodiment, the temperature damper 4 and the baffle 42 are injection molded from the same material.

[0051] Furthermore, such as Figure 5 and Figure 6 As shown, the first door stop 1 has a first slot 11, the first end is inserted into the first slot 11, and the first sealing member 43 is in sealing contact with the inner wall of the first slot 11. The structural design of the slot can limit the first end not only in the moving direction of the temperature damper 4, but also in the air inlet direction, ensuring that the temperature damper 4 can still be accurately positioned after multiple back-and-forth movements.

[0052] In this embodiment, as Figure 3 and Figure 4 As shown, the second door stop 2 has a second slot 21, the second end is inserted into the second slot 21, and the second seal 44 is sealed against the inner wall of the second slot 21. The slot structure design can limit the second end not only in the moving direction of the temperature damper 4, but also in the air inlet direction, ensuring that the temperature damper 4 can be accurately positioned even after multiple back-and-forth movements.

[0053] In this embodiment, as Figure 1 and Figure 2 As shown, the third door stop 3 has an abutting surface near the temperature damper 4, and the first seal 43 or the second seal 44 seals against the abutting surface. Since the third door stop 3 is located in the middle of the moving path of the temperature damper 4, the abutting surface of the third door stop 3 is positioned only on one side of the air inlet direction of the temperature damper 4. This not only ensures the sealing effect between the third door stop 3 and the first seal 43 and the second seal 44, but also avoids interference during the movement of the temperature damper 4.

[0054] Furthermore, the first seal 43 is bent toward the side opposite to the first side 411, so that a portion of the first seal 43 is closer to the first door stop 1 or the third door stop 3. This facilitates an interference fit when the first seal 43 abuts against the first door stop 1 or the third door stop 3, while reducing the contact area of ​​the interference fit and avoiding obstruction of the movement of the temperature damper 4. The second seal 44 is bent toward the side opposite to the second side 412, so that a portion of the second seal 44 is closer to the second door stop 2 or the third door stop 3. This facilitates an interference fit when the second seal 44 abuts against the second door stop 2 or the third door stop 3, while reducing the contact area of ​​the interference fit and avoiding obstruction of the movement of the temperature damper 4.

[0055] Example 2

[0056] This embodiment provides a temperature damper for optimizing the air-mixing ratio of an air conditioning unit based on door stop cooperation. The difference between the temperature damper for optimizing the air-mixing ratio of an air conditioning unit based on door stop cooperation provided in this embodiment and the one in Embodiment 1 is as follows:

[0057] Optionally, such as Figure 7 and Figure 8As shown, baffle 42 is connected to the second side 412. Baffle 42 is inclined towards the side closer to the second seal 44, and baffle 42 is set at an angle to the plane where the second side 412 is located. This reduces the gap between baffle 42 and the inner wall of the hot channel 1002 when the temperature damper 4 is in the preset position, thereby enhancing the effect of baffle 42 on reducing the air mixing ratio in the initial stage of the temperature damper 4's movement. In this embodiment, the damper body 41 extends in an arc shape, and baffle 42 can be flat. The width of baffle 42 and the angle between it and the plane where the damper body 41 is located can be adjusted according to the size of the damper. For example, the angle between baffle 42 and the plane where the damper body 41 is located is 22°, and the width is 5.5 mm.

[0058] In addition, the structure of the air conditioning unit air mixing ratio optimization temperature damper based on door stop cooperation provided in this embodiment is the same as that in the embodiment, and will not be described again here.

[0059] Example 3

[0060] This embodiment provides an air conditioning unit 100, including an air conditioning unit housing, a damper drive structure, and a temperature damper 4 based on door stop cooperation for optimizing air-to-air ratio, as described in Embodiment 1 or Embodiment 2. Both the temperature damper 4 and the damper drive structure are disposed within the air conditioning unit housing and located at the air inlet channel. The damper drive structure drives the temperature damper 4 to move along a preset trajectory to switch between a fully cooling position and a fully heating position. The temperature damper 4 of this air conditioning unit 100 can significantly reduce the front-end air-to-air ratio without sacrificing the maximum airflow in hot mode, thereby improving the performance of the air conditioning unit 100.

[0061] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
