In related technologies, the air blown out by the air conditioner is used to dissipate the heat of the refrigerator. However, this heat dissipation method is limited by the current working mode of the air conditioner. For example, in winter, the air conditioner blows warm air into the car due to heating, which is not conducive to the heat dissipation of the refrigerator. Utility Model Content
[0003] In order to overcome the problems existing in the related art, the present disclosure provides a heat dissipation system of a vehicle refrigerator and a vehicle.

DETAILED DESCRIPTION
[0028] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another, and do not have order and importance.
[0030] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.
[0031] like Figures 1 to 5As shown, the present disclosure exemplarily provides a heat dissipation system for a vehicle-mounted refrigerator. Specifically, the heat dissipation system for the vehicle-mounted refrigerator includes an evaporator 1 of an air conditioner and a refrigerator 2. The refrigerator 2 has a heat dissipation structure 21. A heat dissipation duct 33 is provided between the evaporator 1 and the heat dissipation structure 21. The heat dissipation duct 33 is configured to introduce part of the cold air in the evaporator 1 into the surface of the heat dissipation structure 21.
[0032] Among them, evaporator 1 is the evaporator of the air conditioner ( Figure 1 Only a partial structure of the evaporator is shown as an example), that is, the evaporator 1, on the one hand, serves as a cooling and heating working part of the air conditioner, and on the other hand, provides a cold air source for the heat dissipation system of the vehicle refrigerator provided by the present invention. The provision of the cold air source can be achieved by, for example, leading out a branch for the discharge of cold air on the evaporator 1. In addition, the evaporator 1 can be arranged at the front of the vehicle according to actual needs, for example, it can be arranged at a position below the instrument panel, or it can also be arranged at the rear of the vehicle. For example, in the embodiment to be introduced later, the refrigerator 2 arranged on the center console assembly 3 is closer to the front position of the vehicle, so it is beneficial to shorten the layout of the pipeline by means of the evaporator 1 arranged below the instrument panel.
[0033] like Figure 5 As shown, the refrigerator 2 can be a refrigerator 2 that uses a semiconductor refrigeration sheet for refrigeration. Specifically, the Peltier effect of the semiconductor refrigeration sheet is used to achieve the refrigeration effect of the refrigerator 2. This type of refrigerator has the characteristics of small size and low cost, and is particularly advantageous for use in vehicle-mounted refrigerators with relatively compact space. Considering that the semiconductor refrigeration sheet will generate unwanted heat when working, if it cannot be dissipated in time, it will affect the working efficiency of the semiconductor refrigeration sheet, and further affect the refrigeration effect of the refrigerator. The refrigerator 2 provided in the present disclosure includes a refrigerator body 22 and a heat dissipation structure 21. By setting the heat dissipation structure 21 and making the heat dissipation structure 21 in thermal contact with the semiconductor refrigeration sheet, the heat generated by the semiconductor refrigeration sheet is dissipated in time. The heat dissipation structure 21 can be, for example, a heat dissipation fin, which is conducive to providing a larger heat dissipation area. In addition, the refrigerator 2 can also include a fan 23 for providing further power for introducing cold air into the heat dissipation structure 21.
[0034] By setting a heat dissipation duct 33 between the evaporator 1 and the heat dissipation structure 21, the cold air drawn out from the evaporator 1 can be blown directly to the heat dissipation structure 21 of the refrigerator 2. The direct blowing here is compared with the related art that uses the cold air blown out from the air conditioner (different from the cold air drawn out from the evaporator) to indirectly dissipate the heat for the refrigerator 2, which can provide higher heat dissipation efficiency. Specifically, according to the working characteristics of the evaporator 1, whether the air conditioner is in the cooling mode in summer or the heating mode in winter, the air in the evaporator 1 is always low-temperature (usually 3-8°C) cold air. In this way, the cooling of the refrigerator 2 is no longer limited by the working mode of the air conditioner. For example, in the solution of the related art that uses the wind blown out by the air conditioner to provide heat dissipation for the refrigerator 2, when the air conditioner is in the heating mode in winter, the hot air blown out by the air conditioner is not conducive to providing heat dissipation for the refrigerator 2. The present invention directly introduces low-temperature air into the evaporator 1, so that no matter whether the air conditioner is in cooling or heating mode, it can provide heat dissipation for the refrigerator 2. In addition, since the cold air introduced from the evaporator 1 directly dissipates heat to the refrigerator 2 through the heat dissipation duct 33 instead of being directly discharged into the vehicle, for example, the cold air is not directly discharged into the vehicle in winter, the impact on the temperature inside the vehicle is relatively small.
[0035] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the heat dissipation system of the vehicle refrigerator provided by the present disclosure, by setting a heat dissipation duct 33 between the evaporator 1 of the air conditioner and the heat dissipation structure 21 of the refrigerator 2, and allowing the cold air in the evaporator 1 to be introduced into the surface of the heat dissipation structure 21 through the heat dissipation duct 33, that is, the cold air in the evaporator 1 is used to directly cool the refrigerator 2. On the one hand, the cold air in the evaporator 1 is lower in temperature than the natural wind in the car, which is beneficial to improving the heat dissipation efficiency. On the other hand, since the evaporator 1 is always cold air regardless of whether the air conditioner is cooling or refrigerating, the cooling of the refrigerator is no longer limited by the working mode of the air conditioner, but provides a better heat dissipation effect for the refrigerator.
[0036] In some embodiments, the vehicle refrigerator heat dissipation system provided by the present disclosure further includes a center console assembly 3, which is arranged at the position of the central channel, that is, between the left and right seats, and is usually located between the front and rear seats and slightly close to the front seats, that is, approximately at the position of the front seat armrest. The heat dissipation duct 33 is formed inside the center console assembly 3, and the refrigerator 2 is carried on the center console assembly 3. The heat dissipation structure 21 can be configured to be partially or completely located in the heat dissipation duct 33, or the heat dissipation structure 21 can be arranged outside the heat dissipation duct 33 so that the cold air in the heat dissipation duct 33 can be blown to the heat dissipation structure. Specifically, the heat dissipation system of the vehicle refrigerator provided by the present disclosure uses at least a part of the internal space of the center console assembly 3 as the heat dissipation duct 33. This method of using the internal space of the original center console assembly 3 of the vehicle to form the heat dissipation duct 33 will not have an adverse effect on the vehicle's styling design and does not occupy additional storage space in the vehicle.
[0037] The center console assembly 3 may include a center console frame 31 and a center console outer panel 32 disposed outside the center console frame 31, and the center console frame 31 and the center console outer panel 32 are assembled to form a heat dissipation duct 33. The center console frame 31 is used to fix the center console assembly 3 to the vehicle body. The center console outer panel 32 is used as a decorative part to cover the exposed center console frame 31, and on the other hand, the center console outer panel 32 and the center console frame 31 define a heat dissipation duct 33. In addition, the center console assembly 3 may be provided with an exhaust port 37 connected to the heat dissipation duct 33. For example, the exhaust port 37 may be provided on the center console outer panel 32 to allow the air with a higher temperature to be discharged from the heat dissipation duct 33 after heat exchange with the heat dissipation structure 21. The exhaust port 37 may be constructed in a grille shape, and the opening of the grille faces downward, which is conducive to preventing dust from entering the interior of the heat dissipation duct 33.
[0038] Furthermore, refer to Figure 2 and Figure 3 In some embodiments, the center console exterior panel 32 includes side panels arranged on both sides of the center console frame 31 in the length direction of the vehicle body, and the refrigerator 2 is arranged inside the center console frame 31, wherein the heat dissipation duct 33 includes a first heat dissipation duct 331 arranged on the outer wall of the center console frame 31 and a second heat dissipation duct 332 extending from the first heat dissipation duct 331 to the inside of the center console frame 31. The first heat dissipation duct 331 and the second heat dissipation duct 332 can be integrally formed with the center console frame 31 by injection molding when the center console frame 31 is manufactured. The way in which the refrigerator 2 is arranged inside the center console frame 31 will not have an adverse effect on the styling design of the vehicle and will not occupy additional storage space in the vehicle. Among them, Figure 2 and Figure 3The dotted arrow in the figure is the airflow direction of the cold air. After the cold air drawn from the evaporator 1 enters the center console assembly 3, it flows along the first heat dissipation duct 331 between the center console outer panel 32 and the center console frame 31 and then enters the second heat dissipation duct 332. After exchanging heat with the heat dissipation structure 21, it is discharged from the exhaust port 37. This arrangement in which the main part of the heat dissipation duct 332 is formed between the center console frame 31 and the side panel can minimize the occupation of the central part of the center console assembly 3 and avoid adverse effects on the layout of the central control equipment.
[0039] At least one of the center console exterior panels 32 on both sides is provided with an exhaust port 37 connected to the heat dissipation duct 33. For example, the exhaust ports 37 are provided on the center console exterior panels 32 on both sides, which is conducive to quickly discharging the air after heat exchange and improving the heat dissipation efficiency. In addition, in order to improve the sealing performance of the heat dissipation duct 33, as shown in FIG. Figure 4 As shown, a first sealing member 34 is provided at the joint of the center console frame 31 and the center console exterior panel 32 . The first sealing member 34 may be, for example, a sealing rubber or sponge extending at the joint.
[0040] In other embodiments, Figure 1 As shown, the heat dissipation system of the vehicle refrigerator may further include a first cold air pipeline 11 and a second cold air pipeline 35, the first cold air pipeline 11 is arranged on the evaporator 1 and communicated with the evaporator 1, the second cold air pipeline 35 passes through the center console frame 31 and communicates with the heat dissipation duct 33, and the first cold air pipeline 11 and the second cold air pipeline 35 are detachably connected. The second cold air pipeline 35 passes through the center console frame 31, which means that one end of the second cold air pipeline 35 passes through the center console frame 31 and penetrates into the heat dissipation duct 33, and the other end of the second cold air pipeline 35 remains outside the center console frame 31 to be connected with the first cold air pipeline 11. When the whole vehicle is assembled, the evaporator 1 and the center console assembly 3 are installed separately. Since the first cold air pipeline 11 and the second cold air pipeline 35 are fixedly arranged on the evaporator 1 and the center console assembly 3 respectively, when the evaporator 1 and the center console assembly 3 are respectively installed, the first cold air pipeline 11 and the second cold air pipeline 35 can be connected.
[0041] Furthermore, the first cold air pipeline 11 and the second cold air pipeline 35 have different pipe diameters at least at the joint, so that the first cold air pipeline 11 and the second cold air pipeline 35 can be plugged and matched. The first cold air pipeline has different pipe diameters along the extension direction. For example, the pipe diameter of the end of the first cold air pipeline 11 connected to the evaporator 1 can be larger than the pipe of the end matched with the second cold air pipeline 35, which is conducive to increasing the rate of cold air being drawn out from the evaporator 1. In addition, plugging here means that the end of a pipe with a smaller pipe diameter is inserted into the end of another pipe with a larger pipe diameter, which is more convenient to install.
[0042] In order to improve the sealing performance of the cold air pipeline after plugging, a second seal is provided at the plug-in. Similar to the aforementioned first seal 34, the second seal can be a sealing rubber or sponge provided at the plug-in. Of course, other methods, such as a clamp between the first cold air pipeline 11 and the second cold air pipeline 35, can also achieve a convenient detachable connection. Furthermore, in order to improve the stability of the first cold air pipeline 11 and the second cold air pipeline 35 during operation, for example, to avoid the separation of the two due to vibration during the cold air delivery process, a fixed bracket can be provided on the evaporator 1, or on the center console frame 31, or on the evaporator 1 and the center console frame 31 at the same time, and the fixed bracket can be provided near the position where the first cold air pipeline 11 and the second cold air pipeline 35 are connected.
[0043] According to a second aspect of the embodiments of the present disclosure, there is also provided a vehicle, which includes the heat dissipation system of the vehicle refrigerator in any one of the above embodiments and has all its beneficial effects, which will not be elaborated here.
[0044] In the embodiment in which the heat dissipation duct 33 is formed inside the center console assembly 3, the two seats of the vehicle are respectively located on both sides of the center console assembly 3 in the length direction of the vehicle body, and at least one of the two sides of the center console assembly 3 facing the seat is provided with an exhaust port 37, and the exhaust port 37 is located below the seat in the height direction of the vehicle body. In this way, the hot air in the heat dissipation duct 33 can be discharged in time through the setting of the exhaust port 37, and at the same time, the hot air can be prevented from blowing directly on the driver or passengers by setting the exhaust port 37 below the seat, thereby improving the riding experience.

This application is intended to cover any variations, uses or adaptations of the present disclosure, which follow the general principles of the present disclosure and include common knowledge or customary technical means in the art that are not disclosed in the present disclosure.
