Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle parts technology, specifically to a vehicle refrigerator heat dissipation structure, a vehicle refrigerator, and a vehicle. Background Technology
[0002] Car refrigerators, as a common accessory, typically consist of a semiconductor module, a refrigerator liner, and a storage drawer that can be pulled out from the liner. The storage drawer provides convenient storage for food and beverages. Car refrigerators utilize semiconductor refrigeration technology, based on the thermoelectric effect. When current flows through the semiconductor module, a heating or cooling effect is generated, achieving the purpose of cooling or heating. Specifically, when the semiconductor module starts operating, the current flowing through it creates a temperature difference between its two ends. When the first end of the semiconductor module is the cold end, it cools the storage drawer; when the first end is the hot end, it warms the storage drawer.
[0003] Since the first end of the semiconductor module corresponding to the storage drawer sometimes needs to be used as a cold end and sometimes as a hot end, a heat sink and a fan are often arranged at the first end of the semiconductor module to allow the heat load or cold load of the first end of the semiconductor module to enter the storage drawer more quickly. The heat sink is used to receive the cold load or heat load of the first end of the semiconductor module, and the air generated by the fan when it is working sends the cold load on the heat sink to the storage drawer. In related technologies, regarding the fan blowing air to the storage drawer, an additional and complex dedicated air duct is usually set up in the refrigerator liner, which is not only costly but also occupies space in the refrigerator liner, thus reducing the storage space of the storage drawer. Regarding the fan's return air, it is generally returned through the gap between the storage drawer and the refrigerator liner, but the gap between the storage drawer and the refrigerator liner is small, and the return air resistance is large. Utility Model Content
[0004] This utility model aims to solve at least one of the above-mentioned problems.
[0005] To address the aforementioned problems, this utility model provides a vehicle refrigerator, comprising an inner liner, a fan, a radiator, and a drawer with an open top. The inner liner has a first A sidewall and a first B sidewall arranged opposite each other along a first direction. The first B sidewall has an opening, and the drawer is used to enter and exit the inner liner through the opening. The drawer includes a second A sidewall opposite to the first A sidewall. A vertical airflow guide structure is provided on the side of the second A sidewall facing the first A sidewall or on the side of the first A sidewall facing the second A sidewall. The fan and the radiator are disposed at the bottom wall of the inner liner, and both the radiator and the first A sidewall are on the airflow path of the fan.
[0006] This utility model provides a vehicle refrigerator where the drawer's side wall away from the second A side wall can be the second B side wall. When the drawer is stored inside the inner liner, the second B side wall of the drawer seals the opening of the inner liner, ensuring that the gas inside the inner liner does not leak out. Since the radiator and the corresponding fan are located on the bottom wall of the inner liner below the drawer, the radiator can easily contact the first end of the semiconductor module on the lower part of the inner liner to receive the cold and heat from the first end of the semiconductor module. For example, when the first end of the semiconductor module is the cold end, the radiator above it is used to receive the cold energy from the first end of the semiconductor module.
[0007] Since the radiator and the first A side wall of the inner liner are located in the airflow path of the fan, that is, the fan blows air towards the first A side wall, and the radiator is located between the first A side wall and the fan, and there is a gap between the bottom of the drawer and the bottom wall of the inner liner, when the fan is working, the air blown by the fan can become cold air after passing through the radiator. The fan will gradually blow the cold air along the gap between the bottom of the drawer and the bottom wall of the inner liner towards the first A side wall of the inner liner. When the cold air reaches the first A side wall, it can only move upward between the second A side wall of the drawer and the first A side wall of the inner liner, and finally enter the drawer through the gap between the top of the second A side wall and the top wall of the inner liner to cool the stored items inside the drawer and achieve the refrigeration function of the drawer. In this design, as the cold air moves upward between the second A side wall of the drawer and the first A side wall of the inner liner, a vertical airflow guide structure protrudes from the side of the second A side wall facing the first A side wall, or vice versa. This vertical airflow guide structure allows the upward-moving cold air to enter the drawer more quickly, ultimately improving the drawer's refrigeration effect. Furthermore, since the vertical airflow guide structure is a protrusion on the drawer or inner liner, it is integrally formed with the drawer or inner liner and is not an additional dedicated air duct structure. This reduces the overall cost of the car refrigerator and does not occupy much space inside the inner liner in the first direction, ensuring ample storage space inside the drawer.
[0008] Furthermore, the vertical flow guiding structure includes a flow guiding rib plate disposed on the second A side wall. The flow guiding rib plate extends in a vertical direction, and multiple flow guiding rib plates are disposed thereon. The multiple flow guiding rib plates are disposed at intervals along a second direction, which is perpendicular to the first direction.
[0009] Furthermore, at least a portion of the guide ribs are at different distances from the first A sidewall.
[0010] Furthermore, the radiator and the fan are embedded in the bottom wall of the inner liner, and a bottom guide groove is provided on the inward side of the bottom wall of the inner liner. The bottom guide groove is located on the side of the radiator away from the fan. One end of the bottom guide groove is connected to the radiator, and the other end of the bottom guide groove extends toward the first A side wall.
[0011] Furthermore, the vehicle refrigerator also includes a guide rail device, which includes a guide rail mounting plate located on the lower side of the drawer and fixed relative to the inner liner. The guide rail mounting plate covers the bottom guide groove, and when the drawer is not pulled out from the inner liner, the second A side wall is closer to the first A side wall than the guide rail mounting plate.
[0012] Furthermore, the portion of the guide rail mounting plate corresponding to the heat sink is provided with an opening, which penetrates the guide rail mounting plate vertically.
[0013] Furthermore, the drawer also includes a second B side wall disposed opposite to the second A side wall, and the drawer also includes a second C side wall and a second D side wall disposed opposite to each other, with the portion of the C side wall and the second D side wall near the second B side wall provided with a main return air vent.
[0014] Furthermore, multiple main return air vents are provided, and the multiple main return air vents are distributed sequentially along the first direction, and / or the main return air vents extend along the vertical direction.
[0015] Furthermore, the second C sidewall and the second D sidewall each have an extension portion extending downwards, and the portion of the extension portion near the second B sidewall is provided with an auxiliary return air hole.
[0016] This utility model also provides a vehicle, including the vehicle-mounted refrigerator as described above.
[0017] Since the technological improvements and effects of the vehicle are the same as those of the in-vehicle refrigerator, the vehicle will not be described in detail again. Attached Figure Description

Unless specifically stated otherwise, the term "connection" can refer to a direct connection or an indirect connection.
[0023] See Figure 1 An embodiment of the present invention provides a vehicle refrigerator, comprising an inner liner 1, a fan 4, a radiator 3, and a drawer 2 with an open top. The inner liner 1 has a first A sidewall 11 and a first B sidewall arranged opposite each other along a first direction. The first B sidewall has an opening. The drawer 2 is used to enter and exit the inner liner 1 through the opening. The drawer 2 includes a second A sidewall 21 opposite to the first A sidewall 11. The second A sidewall 21 protrudes from the side facing the first A sidewall 11 or the side facing the first A sidewall 11 from the second A sidewall 21, and a vertical airflow guide structure 211 is provided. The fan 4 and the radiator 3 are disposed at the bottom wall of the inner liner 1, and the radiator 3 and the first A sidewall 11 are both on the airflow path of the fan 4.
[0024] In this embodiment of a vehicle refrigerator, the side wall of drawer 2 away from the second A side wall 21 can be the second B side wall 22. When drawer 2 is stored in the inner liner 1, the second B side wall 22 of drawer 2 seals the opening of the inner liner 1, ensuring that the gas inside the inner liner 1 does not leak out. Since the radiator 3 and the corresponding fan 4 are located on the bottom wall of the inner liner 1 below drawer 2, the radiator 3 can easily contact the first end of the semiconductor module located below the outer side of the inner liner 1 to receive the cold and heat from the first end of the semiconductor module. For example, when the first end of the semiconductor module is the cold end, the radiator 3 above it is used to receive the cold energy from the first end of the semiconductor module.
[0025] Since the radiator 3 and the first A side wall 11 of the inner liner 1 are located on the airflow path of the fan 4, that is, the fan 4 blows air towards the first A side wall 11, and the radiator 3 is located between the first A side wall 11 and the fan 4, and there is a gap between the bottom of the drawer 2 and the bottom wall of the inner liner 1, when the fan 4 is working, the air blown by the fan 4 can become cold air after passing through the radiator 3, and the fan 4 will gradually blow the cold air along the gap between the bottom of the drawer 2 and the bottom wall of the inner liner 1 towards the first A side wall 11 of the inner liner 1. When the cold air moves to the first A side wall 11, it can only move upward between the second A side wall 21 of the drawer 2 and the first A side wall 11 of the inner liner 1, and finally enter the drawer 2 through the gap between the top of the second A side wall 21 and the top wall of the inner liner 1, so as to cool the stored items inside the drawer 2 and realize the refrigeration function of the drawer 2.
[0026] In this design, as the cold air moves upward between the second A side wall 21 of drawer 2 and the first A side wall 11 of inner liner 1, a vertical airflow guide structure 211 protrudes from either the side of the second A side wall 21 facing the first A side wall 11 or the side of the first A side wall 11 facing the second A side wall 21. This vertical airflow guide structure 211 allows the upward-moving cold air to enter the drawer 2 more quickly, ultimately improving the refrigeration effect of drawer 2. Furthermore, since the vertical airflow guide structure 211 is a protrusion on drawer 2 or inner liner, rather than an additional dedicated air duct structure, it reduces the overall cost of the vehicle refrigerator and does not occupy much space inside inner liner 1 in the first direction, ensuring ample storage space inside drawer 2.
[0027] It should be noted that in the car refrigerator, drawer 2 faces away from the first A side wall 11 (that is... Figure 1 The drawer 2 is pulled out in the positive direction of the X-axis. Therefore, the bottom of the outer side wall 21 of the second A side wall of the drawer 2 can be provided with a locking tongue (not shown in the figure) to cooperate with the locking tongue structure at the first A side wall 11 of the inner liner 1 to lock it. This ensures that when the drawer 2 is fully stored in the inner liner 1, the locking tongue and the locking structure are locked relative to each other to ensure that the drawer 2 will not be accidentally pulled out.
[0028] In addition, in the car refrigerator, to ensure the stable movement of drawer 2, a guide rail device (not shown in the figure) can be provided on the inner wall of the inner liner 1, so that drawer 2 can move under the guidance of the guide rail device. On this basis, since drawer 2 is pulled out in a direction away from the first A side wall 11, a protrusion 2112 can also be provided on the outer side of the second A side wall 21 of drawer 2 for connecting with a component of the guide rail device, thereby realizing the movement of drawer 2 under the guidance of the guide rail device and ensuring that drawer 2 can be pulled out to the maximum extent.
[0029] As can be seen, since a latch and a protrusion 2112 need to be installed on the outer side of the second A side wall 21 of drawer 2, a gap must be left between the second A side wall 21 of drawer 2 and the first A side wall 11 of inner liner 1 when drawer 2 is completely stored in inner liner 1. In this embodiment, the vertical airflow guide structure 211, like the latch and the protrusion 2112, is also set in the gap space that already exists between the second A side wall 21 and the first A side wall 11, ensuring that the vertical airflow guide structure 211 can guide the airflow vertically without occupying additional space in the first direction of inner liner 1.
[0030] Optionally, see Figure 2 The vertical flow guiding structure 211 includes a flow guiding rib plate 2111 disposed on the second A side wall 21. The flow guiding rib plate 2111 extends in the vertical direction, and multiple flow guiding rib plates 2111 are disposed thereon. The multiple flow guiding rib plates 2111 are disposed at intervals along a second direction, which is perpendicular to the first direction.
[0031] In this embodiment, the vertical flow guide structure 211 is disposed on the second A side wall 21 of the drawer 2, and is integrally formed with the drawer 2, which facilitates processing and forming. Figure 2 In the indicated orientation, the first direction refers to the X-axis direction, and the second direction refers to the Y-axis direction. The vertical airflow guiding structure 211 specifically includes multiple airflow guiding ribs 2111 protruding from the second A sidewall 21, with the multiple airflow guiding ribs 2111 arranged sequentially along the second direction. These vertically arranged, spaced-apart airflow guiding ribs 2111, which do not contact the first A sidewall 11, can play a role in airflow guidance, rectification, and drag reduction.
[0032] Specifically, these guide ribs 2111 are equivalent to a series of parallel small guide vanes, which force the airflow to flow more parallel to the vertical direction, suppressing the lateral (second direction) flow perpendicular to the mainstream direction and the generation and development of vortices. The presence of these guide ribs 2111 also forces the airflow to become more uniform in the lateral direction. The small channels formed between adjacent guide ribs 2111 restrict the migration of airflow in the lateral direction, making the velocity distribution in each small channel closer to an ideal parabola or fully developing turbulent distribution. The superposition of multiple small channels makes the airflow velocity distribution between the first A sidewall 11 and the second A sidewall 21 more uniform.
[0033] Furthermore, at least a portion of the guide ribs 2111 are at different distances from the first A sidewall 11.
[0034] In this embodiment, since the intervals between some of the guide ribs 2111 and the first A sidewall 11 are different, this non-uniform layout can create a "stepped" or "gradually deformed" flow channel, forcing the airflow to accelerate or decelerate, thereby adapting to the pressure changes in the air duct, which helps to reduce airflow resistance and improve the uniformity of airflow distribution.
[0035] Optionally, see Figure 2 The radiator 3 and the fan 4 are embedded in the bottom wall of the inner liner 1, and the bottom wall of the inner liner 1 has a bottom guide groove 12 on the inward side. The bottom guide groove 12 is located on the side of the radiator 3 away from the fan 4. One end of the bottom guide groove 12 is connected to the radiator 3, and the other end of the bottom guide groove 12 extends toward the first A side wall 11.
[0036] In this embodiment, the heat sink 3 and fan 4 are embedded in the bottom wall of the inner liner 1. This facilitates contact with the semiconductor module below the inner liner 1 and avoids vertically encroaching on the space of the drawer 2. Furthermore, a bottom guide groove 12 is provided on the inward-facing side of the bottom wall of the inner liner 1. For example, the bottom guide groove 12 is formed in a recessed manner on the bottom wall of the inner liner 1. One end of the bottom guide groove 12 can communicate with the heat sink 3, allowing the cool air passing through the heat sink 3 to enter the bottom guide groove 12. Specifically, the heat sink 3 includes multiple heat dissipation fins spaced apart sequentially along a second direction. Each heat dissipation fin extends along a first direction. The connection between one end of the bottom guide groove 12 and the heat sink 3 means that one end of the bottom guide groove 12 communicates with the space between adjacent heat dissipation fins, while the other end of the bottom guide groove 12 can extend to the first A side wall 11 of the inner liner 1. Thus, when the fan 4 is working, for example, when the first end of the semiconductor module corresponding to the heat sink 3 is the cold end, the air blown out by the fan 4 becomes cold air after passing through the space between adjacent heat sink fins, and the fan 4 blows the cold air into the bottom guide groove 12, and moves along the bottom guide groove 12 towards the first A side wall 11. When the cold air moves along the bottom guide groove 12 to the first A side wall 11, it moves upward along the gap between the second A side wall 21 of the drawer 2 and the first A side wall 11 of the inner liner 1, and finally enters the drawer 2 through the gap between the top of the second A side wall 21 and the top wall of the inner liner 1.
[0037] Optionally, see Figures 1 to 4 The car refrigerator also includes a guide rail device, which includes a guide rail mounting plate 51. The guide rail mounting plate 51 is located on the lower side of the drawer 2 and is fixed relative to the inner liner 1. The guide rail mounting plate 51 covers the bottom guide groove 12, and when the drawer 2 is not pulled out from the inner liner 1, the second A side wall 21 is closer to the first A side wall 11 than the guide rail mounting plate 51.
[0038] In this embodiment, as mentioned above, in order for the drawer 2 to move smoothly and stably into and out of the inner liner 1, a guide rail device needs to be provided on the inner wall of the inner liner 1. Here, the guide rail device can be set on the bottom wall of the inner liner 1, which is located below the drawer 2. On this basis, the guide rail device includes a guide rail mounting plate 51, which is fixed relative to the bottom wall of the inner liner 1, and the guide rail mounting plate 51 covers the bottom guide groove 12. Thus, when the fan 4 is working, the air blown out by the fan 4 becomes cold air after passing through the space between adjacent heat dissipation fins, and the fan 4 blows the cold air towards the bottom guide groove 12 and moves along the bottom guide groove 12, and then moves upward along the vertical guide structure 211. During this process, the guide rail mounting plate 51 covers the opening of the bottom guide groove 12, which can make the bottom guide groove 12 form a closed flow channel. Therefore, the guide rail mounting plate 51 can ensure that the cold air will hardly flow out of the bottom guide groove 12 vertically during the movement of the cold air in the bottom guide groove 12 towards the first A side wall 11. This ensures that the cold air moves as far as possible along the bottom guide groove 12 to the bottom between the second A side wall 21 and the first A side wall 11, ensuring the efficiency of the cold air movement at the bottom of the drawer 2. Furthermore, when drawer 2 is not pulled out of inner liner 1, the second A side wall 21 is closer to the first A side wall 11 than the guide rail mounting plate 51, meaning that the guide rail mounting plate 51 will not block the gap between the second A side wall 21 and the first A side wall 11, thereby allowing cold air to smoothly enter the gap between the second A side wall 21 and the first A side wall 11 from the bottom guide groove 12.
[0039] It should be noted that, as Figure 2 and Figure 3 As shown, the guide rail device includes a guide rail mounting plate 51, a fixed rail 52, a sliding rail 53, and a connector 54. The fixed rail 52 is fixed on the guide rail mounting plate 51, and the sliding rail 53 is slidably mounted on the fixed rail 52. The protrusion 2112 of the second A side wall 21 can be connected and fixed to the sliding rail 53 through the connector 54, so as to realize that the drawer 2 moves relative to the fixed rail 52 with the sliding rail 53.
[0040] It should be noted that since the guide rail device is a necessary structure to ensure the movement of drawer 2, it will inevitably occupy the internal space of inner liner 1. However, after the guide rail mounting plate 51 and the bottom guide groove 12 are combined, they can guide the air blown out by fan 4 to the bottom of inner liner 1. This does not require the car refrigerator to be equipped with an additional special air duct. Therefore, it can further avoid the drawer 2 being squeezed in the vertical direction and further reduce the air supply cost.
[0041] Optionally, see Figure 3 The guide rail mounting plate 51 is provided with a through opening 511 in the part corresponding to the heat sink 3, and the through opening 511 penetrates the guide rail mounting plate 51 vertically.
[0042] In this embodiment, when drawer 2 needs to keep its contents warm, the first end of the semiconductor module corresponding to the radiator 3 is switched to the hot end. At this time, the radiator 3 is used to receive the heat from the first end of the semiconductor module. When the fan 4 is working, the air blown out by the fan 4 exchanges heat with the heat sink fins to form hot air. Since the guide rail mounting plate 51 has a through-hole 511 corresponding to the radiator 3, under the principle that hot air rises easily, part of the hot air between adjacent heat sink fins can directly contact the drawer 2 above through the through-hole 511 to heat the drawer 2, and the heat preservation effect of the drawer 2 is better.
[0043] Optionally, see Figure 2 and Figure 3 The drawer 2 also includes a second B side wall 22 disposed opposite to the second A side wall 21, and the drawer 2 also includes a second C side wall 23 and a second D side wall 24 disposed opposite to each other. The portions of the second C side wall 23 and the second D side wall 24 near the second B side wall 22 are provided with main return air holes 25.
[0044] In this embodiment, Figure 2 In the indicated orientation, the second A side wall 21 refers to the front side wall of drawer 2, the second B side wall 22 refers to the rear side wall of drawer 2, the second C side wall 23 refers to the left side wall of drawer 2, and the second D side wall 24 refers to the right side wall of drawer 2; correspondingly, the first A side wall 11 refers to the front side wall of inner liner 1, and the first B side wall refers to the rear side wall of inner liner 1. For example, when the first end of the semiconductor module corresponding to the heat sink 3 is the cold end, when the fan 4 is working, the cold air eventually enters the interior of drawer 2 from the top of the front side wall of drawer 2 and the top wall of inner liner 1, and then, after being disturbed by the airflow inside drawer 2, it can return to the suction side of fan 4 from the main return air hole 25, the left and right side walls of drawer 2 and the left and right side walls of inner liner 1 in sequence, thus achieving air return.
[0045] Since the main return air vent 25 is located on the left and right side walls of drawer 2 near the rear side wall, the cold air entering the drawer 2 from the top of the front side wall needs to travel in a backward direction through the entire interior space of drawer 2 before it can flow out through the main return air vent 25 in order to return to the fan 4. This facilitates sufficient heat exchange between the cold air and the items inside drawer 2, ensuring a relatively uniform temperature inside drawer 2.
[0046] Optionally, see Figure 2 and Figure 3 The main return air vent 25 is provided in multiple ways, and the multiple main return air vents 25 are distributed sequentially along the first direction, and / or the main return air vents 25 extend in the vertical direction.
[0047] In this embodiment, multiple main return air vents 25 are provided, but all of them are located on the left and right side walls of drawer 2 near the rear side wall to ensure heat exchange uniformity, improve return air efficiency, and reduce return air resistance. Furthermore, the main return air vents 25 extend vertically, with their tops extending near the top of drawer 2 and their bottoms extending near the bottom wall of drawer 2 to further improve return air efficiency.
[0048] Optionally, see Figure 2 and Figure 4 The second C sidewall 23 and the second D sidewall 24 are respectively provided with extension portions 26 extending downwards, and the portion of the extension portion 26 near the second B sidewall 22 is provided with an auxiliary return air hole 261.
[0049] In this embodiment, as described above, in Figure 2 In the indicated orientation, the second C side wall 23 refers to the left side wall of drawer 2, and the second D side wall 24 refers to the right side wall of drawer 2. By extending the left and right side walls of drawer 2 downwards to form extensions 26, the extensions 26 can cover the sliding rail 53, preventing it from being directly seen by the passenger when the drawer 2 is pulled out, thus ensuring aesthetics. Furthermore, the extensions 26 are equipped with auxiliary air vents 261, such as... Figure 4 As shown, for example, after the air in drawer 2 flows out from the main return air hole 25 to the left and right side walls of drawer 2 and the left and right side walls of inner liner 1, under the suction of fan 4, the air between the left and right side walls of drawer 2 and the left and right side walls of inner liner 1 will move downward. When it moves to the auxiliary return air hole 261, it can pass through the auxiliary return air hole 261 and return to fan 4, resulting in higher return air efficiency.
[0050] Another embodiment of the present invention includes a vehicle comprising the vehicle-mounted refrigerator as described above.
[0051] Since the technological improvements and effects of the vehicle are the same as those of the in-vehicle refrigerator, the vehicle will not be described in detail again.
[0052] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" and "second" may explicitly or implicitly include at least one of those features.
[0053] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
