Description

Technical Field

[0001] This invention relates to an air conditioner, specifically a vehicle air conditioner. Background Technology

[0002] A vehicle air conditioner consists of a compressor, condenser, throttling element, evaporator, fan, and necessary controllers. It is an air conditioning system used to regulate the temperature and humidity inside the vehicle and provide a comfortable environment for the occupants.

[0003] Because components such as the controller generate a lot of heat, and this heat cannot be dissipated in time, it can cause thermal damage or prevent the system from achieving its maximum efficiency. Currently, most solutions involve adding a fan to cool these heat-generating components. While adding a fan does cool the controller, it also increases the overall size and cost, generates noise, and makes maintenance difficult.

[0004] Accordingly, there is a need in the field for a new type of vehicle air conditioner and a vehicle air conditioner to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, specifically the increased noise and size caused by the addition of fans to dissipate heat from the heat dissipation components of existing vehicle air conditioners, this invention provides a vehicle air conditioner comprising: The casing, on which a fan and a heat exchanger are mounted; and Heat dissipation components generate heat that needs to be dissipated during operation; The housing is provided with heat dissipation holes, and the heat dissipation component is disposed on the housing at the position corresponding to the heat dissipation holes. There is an air communication area between the heat dissipation component and the heat dissipation hole, so that: Under the action of the fan, the airflow can pass through the air communication area, through the heat dissipation component, and reach the negative pressure area inside the housing corresponding to the heat exchanger.

[0006] With the above technical solution, by mounting the fan and heat exchanger on the housing, and with the heat dissipation components corresponding to the positions of the heat dissipation holes on the housing, an air communication area exists between the heat dissipation components and the heat dissipation holes. In this way, under the action of the existing fan, airflow can pass through the air communication area, through the heat dissipation components, and reach the negative pressure area of ​​the corresponding heat exchanger inside the housing. This achieves rapid cooling of the heat dissipation components, avoiding the noise and increased size issues associated with adding a fan, ensuring efficient operation of the heat dissipation components, reducing their damage rate, and resulting in good economic benefits. It is worth mentioning that because the heat exchanger provides the airflow power for heat exchange, i.e., the housing is a negative pressure area for the heat exchanger, when the fan circulates airflow, the airflow can be drawn into the housing through the air communication area and the heat dissipation components.

[0007] In the specific embodiment of the above-mentioned vehicle air conditioner, the heat dissipation component has an air communication structure formed at a position corresponding to and / or near the heat dissipation hole, and the air communication structure forms the air communication area.

[0008] When the above technical solution is adopted, by forming an air communication structure at the position corresponding to and / or near the heat dissipation hole of the heat dissipation component, under the action of the fan, the airflow can pass through the air communication structure and heat dissipation component under the suction action of the negative pressure chamber in the housing, thereby cooling the heat dissipation component.

[0009] In the specific embodiment of the above-mentioned vehicle air conditioner, the air communication structure includes a heat dissipation groove disposed on the heat dissipation component.

[0010] When the above technical solution is adopted, by setting heat dissipation slots on the heat dissipation component, that is, the heat dissipation holes and heat dissipation slots form an air communication channel, it is ensured that under the action of the fan, the airflow can reach the negative pressure area of ​​the corresponding heat exchanger inside the shell through the air communication channel, so as to realize the airflow to quickly cool the heat dissipation component.

[0011] In the specific implementation of the above-mentioned vehicle air conditioner, a heat dissipation plate is provided on the heat dissipation component, and a heat dissipation groove is provided or formed on the heat dissipation plate corresponding to the air communication structure.

[0012] When the above technical solution is adopted, by setting a heat dissipation plate on the heat dissipation component and setting or forming heat dissipation grooves on the heat dissipation plate in the air communication structure, the airflow can pass through the heat dissipation grooves in the air communication area and the heat dissipation holes on the shell, and reach the negative pressure area of ​​the corresponding heat exchanger in the shell through the heat dissipation component under the action of the existing fan, so as to realize the airflow to quickly cool the heat dissipation component.

[0013] In the specific embodiment of the above-mentioned vehicle air conditioner, the length direction of the heat dissipation groove is the direction in which the heat dissipation component approaches the fan; and / or The heat dissipation groove is a through groove provided on the heat dissipation plate.

[0014] By aligning the length of the heat dissipation groove with the direction of the heat dissipation component closer to the fan, the airflow can pass more quickly through the heat dissipation groove and holes in the air communication channel under the action of the fan. This allows the airflow to reach the negative pressure area of ​​the corresponding heat exchanger inside the casing more rapidly, thus achieving faster cooling of the heat dissipation component. Alternatively, providing through slots on the heat dissipation plate can achieve the same effect, both of which accelerate the airflow speed.

[0015] In the specific implementation of the above-mentioned vehicle air conditioner, the heat dissipation slots include multiple groups distributed at intervals, and the number of heat dissipation slots included in each group may be the same or different.

[0016] In the specific embodiment of the above-mentioned vehicle air conditioner, the housing includes a mounting structure, and the heat dissipation component is disposed on the mounting structure; The mounting structure is inclined downwards along the direction towards the fan on the mounting surface near the heat dissipation component.

[0017] The specific implementation of the above-mentioned vehicle air conditioner also includes a water baffle; The water baffle is disposed on the housing at a position corresponding to the space between the fan and the heat dissipation component.

[0018] In the specific embodiment of the above-mentioned vehicle air conditioner, the water baffle includes a U-shaped baffle. The U-shaped baffle is disposed on the housing at a position corresponding to the space between the fan and the heat dissipation component, and encloses at least a portion of the heat dissipation component therein.

[0019] In the specific implementation of the above-mentioned vehicle air conditioner, the heat dissipation component is a controller.

[0020] Those skilled in the art will understand that, in the technical solution of this invention, the vehicle air conditioner includes: a housing on which a fan and a heat exchanger are mounted; and a heat dissipation component, which generates heat that needs to be dissipated during operation; wherein, the housing is provided with heat dissipation holes, the heat dissipation component is disposed on the housing at a position corresponding to the heat dissipation holes, and there is an air communication area between the heat dissipation component and the heat dissipation holes, so that: under the action of the fan, airflow can pass through the air communication area, through the heat dissipation component, and reach the negative pressure area within the housing corresponding to the heat exchanger. This invention addresses the problem of increased noise and volume caused by the addition of a fan to diffuse heat dissipated by the heat dissipation component in the prior art vehicle air conditioner during operation. Instead, under the action of the existing fan, airflow passes through the air communication area, through the heat dissipation component, and is drawn into the negative pressure area of ​​the corresponding heat exchanger within the housing, thereby cooling the heat dissipation component. This significantly improves the heat dissipation effect and enhances economic efficiency. Attached Figure Description

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0029] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. First refer to Figures 1-6 ,Should Figure 1 This is a schematic diagram of the structure of the vehicle air conditioner of the present invention; Figure 2 This is a side view of the vehicle air conditioner of the present invention; Figure 3 This is a bottom view of the vehicle air conditioner of the present invention; Figure 4 This is a schematic diagram of the fan structure of the present invention; Figure 5 This is a schematic diagram of the structure of the heat dissipation component 11 of the present invention; Figure 6 This is a partial cross-sectional view of the vehicle air conditioner of the present invention. (See attached image.) Figures 1-6As shown, the vehicle air conditioner of the present invention includes: a housing 1 on which a fan 12 and a heat exchanger 13 are mounted; and a heat dissipation component 11, which generates heat that needs to be dissipated during operation; wherein, the housing 1 is provided with heat dissipation holes 14, the heat dissipation component 11 is disposed on the housing 1 at a position corresponding to the heat dissipation holes 14, and there is an air communication area between the heat dissipation component 11 and the heat dissipation holes 14, so that: under the action of the fan 12, the airflow can pass through the air communication area, pass through the heat dissipation component 11, and reach the negative pressure area inside the housing 1 corresponding to the heat exchanger 13.

[0031] Specifically, by installing the fan 12 on the upper surface of the housing 1, the heat exchanger 13 on the lower side inside the housing 1, and the heat dissipation component 11 on the position corresponding to the heat dissipation hole 14 on the upper surface of the housing 1, there is an air communication area between the heat dissipation component 11 and the heat dissipation hole 14; in this way, under the action of the existing fan 12, the airflow can pass through the air communication area, the heat dissipation component 11 and the heat dissipation hole 14, and reach the negative pressure area of ​​the heat exchanger 13 inside the housing 1, so as to realize the airflow to quickly cool the heat dissipation component 11, avoid the noise and volume increase caused by adding the fan 12, ensure that the heat dissipation component 11 can operate efficiently, reduce the damage rate, and achieve good economic benefits. It is worth mentioning that, since the heat exchanger 13 provides airflow power for heat exchange, the lower surface of the shell 1 is the airflow inlet side, that is, the inside of the shell 1 is the negative pressure area of ​​the heat exchanger 13. Therefore, when the fan 12 circulates airflow, the airflow can pass through the air communication area and the heat dissipation component 11, and be drawn into the shell 1 through the heat dissipation hole 14. With the help of the negative pressure of the fan 12 and the heat exchanger 13, the airflow passes through the heat dissipation hole 14 to quickly cool down the heat dissipation component 11.

[0032] The housing 1, also known as the air vent grille, is equipped with a fan 12 for cooling the entire vehicle's air conditioning system. Notably, the heat dissipation component 11 is positioned close to the fan 12 to ensure optimal airflow speed at the nearby air outlet, thereby facilitating faster cooling of the heat dissipation component 11 during operation.

[0033] By placing the heat dissipation component 11 on the air outlet grille, the problem of the heat dissipation component 11 occupying space at the bottom of the overall structure is avoided, and the position of the heat dissipation component 11 is raised to avoid the danger of the heat dissipation component 11 being soaked by rainwater or other water flowing downwards, thereby improving the safety and reliability of the heat dissipation component 11.

[0034] Continue reading Figures 1-6 For example, the heat dissipation component 11 has an air communication structure at a position corresponding to and / or near the heat dissipation hole 14, and the air communication structure forms the air communication area.

[0035] Specifically, in the first possible embodiment, by forming air communication structures at positions corresponding to and near the heat dissipation holes 14 on the heat dissipation component 11, under the action of the fan 12, the airflow can pass through the air communication structures corresponding to and near the heat dissipation holes 14 and enter the negative pressure area inside the housing 1 where the heat exchanger 13 is installed, thereby achieving cooling and heat dissipation of the heat dissipation component 11. In a second possible embodiment, by forming an air communication structure at the location corresponding to the heat dissipation hole 14 on the heat dissipation component 11, under the action of the fan 12, the airflow, under the suction of the negative pressure chamber in the housing 1, passes through the air communication structure corresponding to the heat dissipation hole 14 and the heat dissipation hole 14, passes through the heat dissipation component 11, and enters the negative pressure area in the housing 1 where the heat exchanger 13 is installed from the heat dissipation hole 14, thereby achieving cooling and heat dissipation. In a third possible embodiment, by forming a communication structure near the heat dissipation hole 14 on the heat dissipation component 11, under the action of the fan 12, the airflow, under the suction of the negative pressure chamber in the housing 1, passes through the air communication structure near the heat dissipation hole 14 and the heat dissipation hole 14, passes through the heat dissipation component 11, thereby achieving cooling and heat dissipation. In the first embodiment, the airflow effect is the best, but the structure is relatively complex. In the second embodiment, the airflow efficiency is faster, and the structure is relatively simple, achieving direct airflow and ensuring the cooling effect. In the third embodiment, the airflow effect is average, but airflow can still be achieved, thus achieving the cooling effect.

[0036] The air communication structure and the heat dissipation hole 14 form a communication channel for airflow. That is, since the inside of the shell 1 is a negative pressure area of ​​the heat exchanger 13, there is suction inside the shell 1. The airflow can be drawn into the heat exchanger 13 under the action of the fan 12. At this time, the airflow needs to pass through the communication channel to cool down the heat dissipation component 11 during the flow process.

[0037] Continue reading Figures 1-6 For example, the air communication structure includes a heat dissipation groove 111 disposed on the heat dissipation component 11.

[0038] Specifically, by providing a heat dissipation groove 111 on the heat dissipation component 11, that is, the heat dissipation hole 14 and the heat dissipation groove 111 form a communication channel for airflow, under the action of the existing fan 12, the airflow can pass through the airflow communication channel through the heat dissipation component 11 to reach the negative pressure area of ​​the corresponding heat exchanger 13 inside the housing 1, so as to realize the airflow to quickly cool the heat dissipation component 11.

[0039] Continue reading Figures 1-6 For example, the heat dissipation component 11 is provided with a heat dissipation plate 112, and the air communication structure is provided with or formed with heat dissipation grooves 111 on the heat dissipation plate 112.

[0040] In one possible embodiment, by providing a heat dissipation plate 112 on the heat dissipation component 11 and providing a heat dissipation groove 111 on the heat dissipation plate 112 in the air communication structure, the airflow can reach the negative pressure area of ​​the heat exchanger 13 inside the housing 1 through the heat dissipation groove 111 on the heat dissipation plate 112 and the heat dissipation hole 14 on the housing 1 under the action of the existing fan 12, thereby realizing the airflow to quickly cool and dissipate heat from the heat dissipation component 11.

[0041] In another possible embodiment, by providing a heat dissipation plate 112 on the heat dissipation component 11, and the air communication structure corresponding to the heat dissipation groove 111 formed on the heat dissipation plate 112, under the action of the existing fan 12, the airflow can pass through the heat dissipation groove 111 and heat dissipation hole 14 formed on the heat dissipation plate 112, and reach the negative pressure area of ​​the heat exchanger 13 inside the housing 1, so as to realize the airflow to quickly cool the heat dissipation component 11.

[0042] The heat sink 112 is disposed on the end face of the heat dissipation component 11 that contacts the housing 1. This allows airflow to quickly pass through the heat dissipation holes 14 in the heat sink 11 and the housing 1 under the action of the fan 12, and then rapidly dissipate from the end face of the heat dissipation component 11 that contacts the heat dissipation holes 14, resulting in good heat dissipation. Alternatively, the heat sink 112 can be disposed on other end faces of the heat dissipation component 11, allowing the heat generated during operation to be diffused in multiple directions.

[0043] It is worth mentioning that those skilled in the art will understand that the purpose of providing heat dissipation channels on the heat sink 112 or forming heat dissipation channels on the heat sink 112 is to form heat dissipation channels with the heat dissipation holes 14 and to increase the heat dissipation surface of the heat dissipation component 11. However, this is not limiting. Those skilled in the art can also choose a heat sink 112 with grooves as needed, or a heat sink 112 with grooves formed by molding a regular heat sink 112. Such adjustments do not deviate from the principle of the present invention and therefore will also fall within the protection scope of the present invention.

[0044] Continue reading Figures 1-6 For example, the length direction of the heat dissipation groove 111 is the direction of the heat dissipation component 11 near the fan 12; and / or the heat dissipation groove 111 is a through groove provided on the heat dissipation plate 112.

[0045] In one possible embodiment, by aligning the length of the heat sink 111 with the direction of the heat dissipation component 11 closer to the fan 12, the airflow can pass through the heat sink 111 and the heat dissipation hole 14 in the air communication area more quickly under the action of the fan 12. The airflow can then pass through the heat dissipation component 11 more quickly until it reaches the negative pressure area of ​​the corresponding heat exchanger 13 inside the housing 1, thereby achieving faster cooling of the heat dissipation component 11.

[0046] In another possible embodiment, a through slot is provided on the heat sink 112, so that airflow can be input from the side closer to the fan 12 or from the side relative to the fan 12, so that airflow from both sides of the heat sink 11 can pass through the through slot and heat dissipation hole 14, pass through the heat sink 11 and reach the negative pressure area of ​​the corresponding heat exchanger 13 inside the housing 1.

[0047] Continue reading Figures 1-6 For example, the heat dissipation groove 111 includes multiple groups distributed at intervals, and the number of heat dissipation grooves 111 included in each group of heat dissipation grooves 111 may be the same or different.

[0048] Specifically, airflow is delivered through the heat dissipation channels formed by multiple sets of heat dissipation slots 111 and corresponding heat dissipation holes 14, enabling the airflow to cool the heat dissipation component 11 under the action of the fan 12. The multiple sets of heat dissipation slots 111 facilitate the dissipation of heat generated by the heat dissipation component 11 during operation, thereby increasing the heat dissipation area.

[0049] In each group of heat dissipation channels 111, the number of heat dissipation channels 111 is the same, meaning that multiple groups of heat dissipation channels are evenly distributed. These multiple groups of heat dissipation channels not only maximize the heat dissipation area of ​​the heat dissipation component 11, but also guide airflow more systematically through the multiple groups of channels 111, ensuring effective heat dissipation. Even if the number of heat dissipation channels 111 in each group of heat dissipation channels 111 is different, this still allows for proper airflow guidance.

[0050] The depth of the heat dissipation channel can be selected based on the thickness of the heat sink 112. The depth of the heat dissipation channel should be as large as possible while being less than the thickness of the heat sink 112. This will help to form a larger heat dissipation channel, ensuring more airflow and guaranteeing the heat dissipation effect.

[0051] It is worth mentioning that the heat dissipation holes 14 and the heat dissipation grooves are arranged opposite each other to form a heat dissipation channel, that is, a heat dissipation channel is formed between the lower end surface of the heat dissipation component 11 and the upper end surface of the housing 1, which enables the airflow generated by the heat dissipation component 11 in the working state. The heat dissipation channel can guide the airflow generated by the heat dissipation component 11 in the working state, but this is not limiting. Those skilled in the art can also add heat dissipation channels or the like to the heat dissipation surface of the heat dissipation component 11 as needed. Such adjustments do not deviate from the principle of the present invention and therefore will also fall within the protection scope of the present invention.

[0052] Continue reading Figures 1-6 For example, the housing 1 includes a mounting structure 15, and the heat dissipation component 11 is disposed on the mounting structure 15; the mounting surface of the mounting structure 15 near the heat dissipation component 11 is inclined downward in the direction toward the fan 12.

[0053] By mounting the heat dissipation component 11 on the mounting structure 15 that is inclined downwards along the direction of the fan 12, the heat generated by the heat dissipation component 11 during operation can be quickly dissipated through the inclined mounting structure 15, thus ensuring the heat dissipation effect.

[0054] It is worth mentioning that the mounting structure 15 is inclined downwards along the direction of the fan 12. Firstly, this helps to increase the airflow speed through the heat dissipation holes 14 provided on the mounting structure 15. Secondly, it increases the contact area between the heat dissipation component 11 and the mounting structure 15, improving the structural rigidity of the installation. As shown in the figure, the opening of the heat dissipation channel faces the fan 12 and is inclined downwards towards the fan 12, which facilitates the rapid flow of external airflow through the heat dissipation holes 14 and heat dissipation slots 111 of the heat dissipation channel. Ideally, the angle between the mounting structure 15 and the horizontal plane should be maintained between 3 and 30 degrees to maintain the optimal airflow entry speed and ensure the ease of installation of the heat dissipation component 11.

[0055] The mounting structure 15 can be close to the heat dissipation surface of the heat dissipation component 11, and the heat sink on the lower surface of the heat dissipation component 11 is in contact with the mounting structure 15. By mounting the heat dissipation component 11 on the inclined lower surface facing the fan 12, the airflow from the external environment can more quickly dissipate heat from the heat dissipation component 11, thus improving the heat dissipation effect.

[0056] Continue reading Figures 1-6 For example, it also includes a baffle plate 16; the baffle plate 16 is disposed on the housing 1 at a position corresponding to the space between the fan 12 and the heat dissipation component 11.

[0057] Specifically, a baffle plate 16 is provided between the heat dissipation component 11 and the fan 12 to prevent water from flowing down and soaking the heat dissipation component 11. It also provides protection against rain splashes and ensures the waterproof effect of the heat dissipation component 11.

[0058] The highest point of the baffle plate 16 should not be higher than the highest point of the heat dissipation component 11, so as to avoid the structure of the baffle plate 16 affecting the heat dissipation of the heat dissipation component 11, while ensuring the protective function of the baffle plate 16 for the heat dissipation component 11.

[0059] The structure of the water-blocking plate 16 can be a water-blocking plate 16, a water-blocking block, or a combination of both. Those skilled in the art will understand that the water-blocking structure only needs to achieve the function of blocking water flow. Although combined... Figures 1-6 The description refers to the water baffle 16, but this is not limiting. Those skilled in the art can choose water baffles with different structures as needed. Such adjustments do not deviate from the principles of the present invention and therefore will also fall within the protection scope of the present invention.

[0060] Continue reading Figures 1-6 For example, the baffle 16 includes a U-shaped baffle disposed on the housing 1 at a position corresponding to the space between the fan 12 and the heat dissipation component 11 and enclosing at least a portion of the heat dissipation component 11 therein.

[0061] Specifically, by using a U-shaped baffle to waterproof the heat dissipation component 11, the heat dissipation component 11 is protected from multiple angles while ensuring that the airflow intake side of the heat dissipation component 11 is unobstructed, so that the heat dissipation component 11 can cool and dissipate the heat generated during operation by taking in air from the side.

[0062] The U-shaped baffle provides protection for the heat dissipation component 11 in three directions, maximizing the protection of the protector, while the air intake side can quickly draw in air to dissipate heat from the heat dissipation component 11.

[0063] It is worth mentioning that the height of the U-shaped baffle can be selected such that the height of one side is the same as the height of the main body of the heat dissipation component 11, and the height of the other two sides is slightly lower than the maximum height of the heat dissipation component 11, as long as it can ensure the protection of the heat dissipation component 11.

[0064] In the specific implementation of the above-mentioned vehicle air conditioner, the heat dissipation component 11 is a controller.

[0065] The controller in a vehicle air conditioner is not only a component that generates a lot of heat, but it is also a core component with high economic costs. Therefore, heat dissipation of the controller is very important. By mounting the controller on the upper surface of the housing 1 near the fan 12, and mounting the heat exchanger 13 on the inner side of the housing 1 near the lower surface of the housing 1, under the action of the existing fan 12, the airflow passes through the air circulation structure and heat dissipation component 11, and is finally drawn into the corresponding negative pressure area inside the housing 1 through the controller, thereby achieving rapid cooling of the controller.

[0066] The above-described embodiments and various extended embodiments all achieve cooling and heat dissipation of the heat dissipation component 11 by means of the airflow passing through the air communication area and the heat dissipation component 11 being drawn into the negative pressure area of ​​the corresponding heat exchanger 13 inside the housing 1 under the action of the existing fan 12. The heat dissipation effect is obvious and the economic benefits are improved.

[0067] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
