[0054] With the increasing popularity of new energy vehicles, the driving range and comfort of electric vehicles have become the focus of users' attention. As one of the heating systems in electric vehicles, the PTC heater can quickly and efficiently convert electrical energy into heat energy, providing a comfortable heating effect for the vehicle interior. The PTC heater is fixed inside the air conditioning unit. The PTC heater assembly plays an important role in improving the comfort and user experience of new energy vehicles and is also one of the essential key components of new energy vehicles.

[0055] In summer, users often turn on the air conditioning when driving new energy vehicles. Condensation easily forms on the outer surface of the PTC heater housing (that is, inside the air conditioning assembly). The PTC heater housing is equipped with a water-absorbing sponge to absorb the condensation and allow it to flow out. However, the water-absorbing sponge has a maximum absorption limit. When the water-absorbing sponge is saturated, condensation will flow out into the passenger compartment from the fixing opening between the PTC heater and the air conditioning unit, resulting in a very poor user experience.

[0056] In view of this, this application proposes an air conditioning assembly, which includes an air conditioning unit, a first mounting part, and a PTC heater. The first mounting part is disposed in the air conditioning unit and has a first receiving space and a first opening communicating with the first receiving space. The PTC heater is received into the first receiving space through the first opening. The first mounting part includes a first segment that surrounds the first opening. A first sealing ring is provided between the inner circumferential surface of the first segment and the PTC heater to prevent condensate formed in the air conditioning unit from flowing out of the first opening.

[0057] In the above solution, the inner circumferential surface of the first segment can be tightly fitted with the first sealing ring between the PTC heater and the first sealing ring. The first sealing ring forms an effective barrier that can reliably prevent condensate from flowing out from the first opening, thereby improving the reliability and stability of the air conditioning assembly, reducing the probability of condensate leakage, and improving the passenger's user experience.

[0058] For ease of explanation, the following embodiments use an air conditioning assembly according to an embodiment of this application as an example.

Figure 6 A structure diagram of a cover plate according to an embodiment of the present application is shown in the figure. Figure 7 A side view of a cover plate according to an embodiment of the present application is shown in the figure. Figure 8 A structure diagram of a first mounting part according to an embodiment of the present application is shown in the figure.

[0060] Please refer to Figures 1 to 5 The air conditioning assembly 100 includes an air conditioning box body 110, a first mounting part 120, and a PTC heater 130. The first mounting part 120 is arranged on the air conditioning box body 110. The first mounting part 120 has a first accommodating space 121 and a first opening 122 in communication with the first accommodating space 121. The PTC heater 130 is accommodated into the first accommodating space 121 through the first opening 122. The first mounting part 120 includes a first section 140 surrounding the first opening 122. A first sealing ring 150 is arranged between the inner circumferential surface of the first section 140 and the PTC heater 130 to prevent the condensed water formed by the air conditioning box body 110 from flowing out of the first opening 122.

[0061] The first mounting part 120 is arranged on the air conditioning box body 110. The first mounting part 120 has a first accommodating space 121. The PTC heater 130 is arranged in the first accommodating space 121. The first opening 122 makes the first accommodating space 121 of the first mounting part 120 communicate with the outside. The PTC heater 130 can enter the first accommodating space 121 from the first opening 122.

[0062] The PTC heater is accommodated into the first accommodating space 121 through the first opening 122, which facilitates the installation and disassembly of the PTC heater. In the production and assembly process, the PTC heater can be conveniently loaded into the accommodating space through the first opening 122. In the later maintenance or repair, the PTC heater can also be easily taken out, which improves the production and maintenance efficiency.

[0063] The arrangement of the first mounting part 120 makes the PTC heater have a specific installation position in the air conditioning box body 110. The overall layout is compact and reasonable. The space in the air conditioning box body 110 is effectively utilized. The internal structure of the air conditioning assembly 100 is optimized. The arrangement of each component is more regular and orderly.

[0064] The air conditioning assembly 100 generates condensed water in the first accommodating space 121 when it is running. The condensed water can flow to the passenger compartment of the vehicle from the first opening 122, which reduces the comfort of the passengers. Therefore, the first sealing ring 150 is arranged on the inner circumferential surface of the first section 140, that is, in the first accommodating space 121. The first sealing ring 150 is located between the PTC heater 130 and the first section 140.

[0065] Exemplarily, the first sealing ring 150 can be a part of the PTC heater 130, the first sealing ring 150 can also be a part of the first mounting portion 120, and the first sealing ring 150 can also be an independent part. When the first sealing ring 150 is a part of the PTC heater 130 or the first mounting portion 120, the first sealing ring 150 can be integrally manufactured with the PTC heater 130 or the first mounting portion 120, thereby reducing the manufacturing cost of the air conditioning assembly 100 and improving the assembly efficiency of the air conditioning assembly 100.

[0066] The material of the first sealing ring 150 can be selected from rubber materials such as nitrile rubber, fluororubber, and silicone rubber. The nitrile rubber can work for a long time at about 120°C. The fluororubber has excellent high-temperature resistance and chemical corrosion resistance and can withstand high temperatures of 200-300°C. The silicone rubber can be used at high temperatures of about 250°C.

[0067] The inner circumferential surface of the first section 140 can be tightly attached to the first sealing ring 150 between the PTC heater 130, and the first sealing ring 150 forms an effective barrier to reliably block the condensed water from flowing out of the first opening 122, thereby improving the reliability and stability of the air conditioning assembly 100, reducing the failure probability caused by the leakage of the condensed water, and improving the use experience of the passengers.

[0068] Please refer to Figures 1 to 8 In the embodiment, the PTC heater 130 includes a cover plate 160 and a heating electric core assembly 170. Along the thickness direction X of the cover plate 160, the cover plate 160 includes oppositely arranged first and second side surfaces 161 and 162. The first side surface 161 includes an intermediate region 161A and a rim region 161B surrounding the intermediate region 161A. The heating electric core assembly 170 is arranged in the intermediate region 161A, and the first sealing ring 150 is arranged in the rim region 161B.

[0069] The first side surface 161 faces the first containing space 121, and the second side surface 162 is away from the first containing space 121. The cover plate 160 is arranged in the first containing space 121. The first side surface 161 includes the intermediate region 161A and the rim region 161B surrounding the intermediate region 161A. It can be understood that the rim region 161B surrounds the intermediate region 161A, and the rim region 161B is located around the intermediate region 161A. The heating electric core assembly 170 is arranged in the intermediate region 161A, and the first sealing ring 150 is arranged in the rim region 161B.

[0070] The rim region 161B is located at the region where the cover plate 160 abuts against the first section 140, and the first sealing ring is arranged in the rim region 161B. That is, the first sealing ring 150 is arranged between the first section 140 and the PTC heater 130 to prevent the condensed water formed by the air conditioning assembly 100 from flowing out of the first opening 122.

[0071] The first sealing ring 150 is arranged at the edge area 161B, so that the gap between the PTC heater 130 and the inner circumferential surface of the first section 140 of the first mounting portion 120 can be sealed more accurately. Since the edge area 161B is usually the position where condensed water is most likely to penetrate and flow out, the first sealing ring 150 arranged at this position can directly and effectively block the condensed water from leaking from the joint between the PTC heater 130 and the first mounting portion 120, and the sealing is more targeted than other positions, thereby significantly improving the sealing effect.

[0072] The heat-generating cell assembly 170 is arranged at the middle area 161A, and the first sealing ring 150 is arranged at the edge area 161B, so that the heat generated by the heat-generating cell assembly 170 has a relatively small effect on the first sealing ring 150. The first sealing ring 150 generally has a certain temperature tolerance range, and excessive heating can cause it to age and deform, thereby affecting the sealing performance. Reducing the degree of influence of high temperature on the first sealing ring 150 helps to prolong the service life of the sealing ring and maintain long-term stable sealing performance.

[0073] Further, the heat-generating cell assembly 170 is arranged at the middle area 161A, and the first sealing ring 150 is arranged at the edge area 161B, which can improve the sealing effect, reduce the probability of condensed water flowing out from the edge area 161B, and improve the user's experience.

[0074] Please refer to Figures 1 to 8 In the embodiment, the air conditioning assembly 100 further comprises a second sealing ring 151, which is arranged at the edge area 161B and surrounds the first sealing ring 150. The second sealing ring 151 is arranged in a spaced manner with the first sealing ring 150 to form a sealing groove 180, and the first section 140 is arranged in the sealing groove 180.

[0075] The second sealing ring 151 is arranged at the edge area 161B, the first sealing ring 150 and the second sealing ring 151 are arranged in a spaced manner, and the second sealing ring 151 surrounds the first sealing ring 150, so that the sealing groove 180 is formed between the first sealing ring 150 and the second sealing ring 151, the first section 140 is inserted and matched with the sealing groove 180, and the first section 140 is arranged in the sealing groove 180.

[0076] The first sealing ring 150 is tightly attached to the inner circumferential surface of the first section 140, and the second sealing ring 151 is tightly attached to the outer circumferential surface of the first section 140. It can be understood that even if the first sealing ring 150 is not tightly attached to the inner circumferential surface of the first section 140 due to processing or other reasons, the condensed water is only located in the sealing groove 180 due to the arrangement of the second sealing ring 151, and the second sealing ring 151 plays a role of secondary protection, so that the condensed water is difficult to flow out of the first containing space 121 from the edge area 161B, thereby improving the user's experience.

[0077] The second sealing ring 151 is arranged around the first sealing ring 150 and forms a sealing groove 180 with the first sealing ring 150, and the first section 140 is arranged in the sealing groove 180. This structure makes the sealing groove 180 cooperate with the first sealing ring 150 and the second sealing ring 151, and when the first sealing ring 150 and the second sealing ring 151 are both part of the cover plate 160 of the PTC heater 130, the first sealing ring 150 and the second sealing ring 151 can also make the PTC heater 130 more stably fixed on the air conditioning assembly 100.

[0078] Further, the second sealing ring 151 is arranged apart from the first sealing ring 150 to form the sealing groove 180, and the first section 140 is arranged in the sealing groove 180, which can play a double sealing effect at the joint of the first mounting portion 120 and the cover plate 160, further reducing the probability of condensate water leaking from the first mounting portion 120 and the cover plate 160, and improving the user's comfort.

[0079] Please refer to Figures 1 to 8 In this embodiment, the first sealing ring 150 is attached to the inner circumferential surface of the first section 140, and the second sealing ring 151 is attached to the outer circumferential surface of the first section 140.

[0080] The first sealing ring 150 is attached to the inner circumferential surface of the first section 140, which can tightly fit the inner gap between the PTC heater 130 and the first section 140, effectively preventing condensate water from leaking from the inside, and the second sealing ring 151 is attached to the outer circumferential surface of the first section 140, which can seal the outer gap, further preventing condensate water from leaking from the installation of the first section 140 and the cover plate 160, and improving the user's comfort.

[0081] Please refer to Figures 1 to 8 In this embodiment, a sealing glue layer is arranged between the second sealing ring 151 and the first section 140, and between the first sealing ring 150 and the first section 140.

[0082] The sealing glue layer is arranged between the second sealing ring 151 and the first section 140, and between the first sealing ring 150 and the first section 140, which can fill the microscopic irregular gaps that may exist on the surface of the sealing ring and the first section 140, further enhancing the sealing effect.

[0083] Even if the surface of the sealing ring and the first section 140 is not smooth enough or deforms slightly after long-term use, the sealing glue layer can tightly fit and prevent condensate water from penetrating through these small gaps, ensuring the tightness of the seal.

[0084] Please refer to Figures 1 to 8 In this embodiment, the cover plate 160 is provided with a plurality of fixing portions 190, and each fixing portion 190 is fixed to the air conditioning box body 110 by a fastening bolt.

[0085] By using the fastening bolts to fix the plurality of fixing portions 190 of the cover plate 160 to the air conditioner case 110, a firm connection between the PTC heater and the air conditioner case 110 is achieved. Compared with other connection methods such as buckles, clamps, etc., the fastening bolts have higher connection strength and reliability. They can withstand greater tension, pressure and shear force, ensuring that the PTC heater can be stably installed on the air conditioner case 110 during the operation of the air conditioner, without loosening, displacement and other phenomena, ensuring the structural integrity of the entire air conditioner assembly 100.

[0086] For example, the plurality of fixing portions 190 are arranged at intervals along the circumference of the cover plate 160. The plurality of fixing portions 190 cooperate with the fastening bolts to position and fix the PTC heater 130 from multiple positions, making the position of the PTC heater 130 in the air conditioner case 110 more accurate and stable. This multi-point fixing method can accurately control the relative position of the PTC heater 130 and the air conditioner case 110, avoid affecting its normal work or interfering with other components due to position deviation, thereby improving the assembly accuracy of the entire air conditioner assembly 100.

[0087] Specifically, the cover plate 160 is provided with a plurality of fixing portions 190, each of which is fixed to the air conditioner case 110 by a fastening bolt, which can firmly fix the PTC heater 130 on the air conditioner case 110, reduce the probability of falling off between the PTC heater 130 and the air conditioner case 110, and improve the use stability and reliability of the air conditioner assembly 100.

[0088] In some embodiments, the air conditioner case 110 is provided with a plurality of connecting portions, which cooperate with the plurality of fixing portions 190 to fix the PTC heater 130 to the air conditioner case 110.

[0089] Please refer to Figures 1 to 8 In this embodiment, along the blowing direction Y of the blower, the first mounting portion 120 includes oppositely arranged first and second side walls 123 and 124, the first side wall 123 is provided with a second opening 123A, and the second side wall 124 is provided with a third opening 124A, at least part of the second opening 123A and the third opening 124A are oppositely arranged.

[0090] The air conditioner is provided with a blower, which can blow air to the PTC heater 130. For example, the air can enter the first containing chamber from the second opening 123A, then pass through the PTC heater 130, and then exit the first containing chamber from the third opening 124A.

[0091] The second opening 123A is arranged on the first side wall 123 of the first mounting portion 120, and the third opening 124A is arranged on the second side wall 124, and the second opening 123A and the third opening 124A are at least partially arranged opposite to each other, so that the air flow is smoother, the air can enter from the second opening 123A, pass through the first mounting portion 120, and then flow out from the third opening 124A after being heated by the PTC heater 130, which helps to guide the air flow direction in the air conditioner assembly 100, realizes more efficient air transmission, and improves the air conditioning heating efficiency.

[0092] Please refer to Figures 1 to 8 In this embodiment, the second opening 123A, the third opening 124A, and at least part of the heating cell assembly 170 are arranged opposite to each other along the air blowing direction Y of the air blower.

[0093] The air blower blows the air from the second opening 123A to the heating cell assembly 170, and then the air blows out from the third opening 124A, thereby completing the heating of the air.

[0094] The second opening 123A, the third opening 124A, and at least part of the heating cell assembly 170 are arranged opposite to each other along the air blowing direction Y of the air blower, so that the air can flow through the heating cell assembly 170 more directly after being blown by the air blower. In this way, the air flow can more efficiently exchange heat with the heating cell assembly 170, and in the heating mode, the air can more fully absorb the heat generated by the heating cell assembly 170, thereby improving the heating efficiency of the air conditioner. At the same time, this direct heat exchange path reduces heat loss and ensures efficient use of heat, improving the energy utilization efficiency of the entire air conditioning system.

[0095] Please refer to Figures 1 to 8 In this embodiment, the PTC heater 130 further includes a first housing 200, and the heating cell assembly 170 is fixed to the first housing 200, and the first housing 200 is detachably arranged on the cover plate 160.

[0096] The heating cell assembly 170 is fixed to the first housing 200, and the first housing 200 is detachably arranged on the cover plate 160, so that when the heating cell assembly 170 fails or needs to be maintained, the first housing 200 can be easily detached from the cover plate 160. This avoids the complex disassembly operation of the entire PTC heater, and only the first housing 200 needs to be operated, thereby greatly reducing the difficulty and time cost of maintenance. For example, when the performance of the heating cell assembly 170 is detected to be degraded or damaged, the maintenance personnel can quickly detach the first housing 200, and check, repair or replace the heating cell assembly 170 alone, without the need for a large amount of disassembly work on other parts of the PTC heater.

[0097] The vehicle according to any one of the embodiments of the application comprises a vehicle body and the air conditioning assembly 100 according to any one of the embodiments of the application, and the air conditioning assembly 100 is fixedly installed on the vehicle body.

[0098] The vehicle according to the embodiments of the application can tightly adhere the inner circumferential surface of the first section 140 to the first sealing ring 150 between the PTC heater 130, and the first sealing ring 150 forms an effective barrier to reliably block the condensed water from flowing out of the first opening 122, thereby improving the reliability and stability of the air conditioning assembly 100, reducing the probability of condensed water leakage, and improving the use experience of passengers.
