[0027] Please also read Figures 1 to 6 Now, the vehicle-mounted projector and the vehicle provided by the utility model are described. The vehicle-mounted projector includes a mounting housing 1, a projector controller 2 and a vehicle-mounted evaporator. The projector controller 2 is arranged in the mounting housing 1. The vehicle-mounted evaporator has a cooling part 54 that can contact the projector controller 2. The cooling part 54 can exchange heat with the projector controller 2 to cool the projector controller 2.

[0028] Compared with the prior art, the vehicle-mounted projector provided in this embodiment utilizes the evaporator of the existing vehicle-mounted refrigerator in the vehicle as the vehicle-mounted evaporator, and directly contacts the projector controller 2 through the cooling part 54 to achieve heat dissipation and cooling of the projector controller 2, eliminating the need for a cooling fan, avoiding the generation of noise, reducing the space occupied by the structure, and improving the integrity of the entire vehicle layout.

[0029] In this embodiment, when the vehicle-mounted projector is working, the working temperature at the position of the projector controller 2 is the highest, and it needs to be cooled to ensure the normal use of the vehicle-mounted projector. The vehicle-mounted evaporator is part of the existing cooling structure inside the vehicle, and the evaporator of the vehicle refrigerator can be used, avoiding the cumbersome structure caused by setting a cooling fan in the installation shell 1, reducing the structural volume of the vehicle-mounted projector, and improving the integrity of the vehicle layout.

[0030] During installation, when the vehicle refrigerator 4 is selected as the vehicle evaporator, the vehicle refrigerator 4 can be selected to be set in the installation shell 1, and the side wall of the refrigerator evaporator 45 is directly in contact with the side wall or top wall of the projector controller 2 to achieve a cooling effect on the projector controller 2; the vehicle refrigerator 4 can also be set outside the installation shell 1, and the cooling pipe 51 connected to the refrigerator evaporator 45 and extending into the installation shell 1 is in contact with the projector controller 2 to achieve heat exchange, thereby achieving a heat dissipation and cooling effect on the projector controller 2.

[0032] For details, please refer to Figure 3 The vehicle-mounted evaporator is arranged in the installation shell 1, and the side wall of the vehicle-mounted evaporator can be directly in contact with the side wall of the projector controller 2.

The heat-conducting layer 3 can be made of a metal material component with good thermal conductivity, which helps to improve the heat exchange efficiency.

[0036] In one possible implementation, see Figure 1 and Figure 5 , a horizontally or vertically extending inner groove 21 is provided on the side wall of the projector controller 2, and the cooling unit 54 is embedded in the inner groove 21. The inner groove 21 provided on the projector controller 2 adopts an inwardly recessed structure, which provides sufficient installation space for the cooling unit 54, facilitates the effective embedding of the cooling unit 54, helps to increase the contact area between the outer peripheral wall of the cooling unit 54 and the projector controller 2, improves the heat exchange efficiency, and enhances the cooling effect.

[0037] As a parallel embodiment, see Figure 2 and Figure 6 The projector controller 2 is provided with a through hole 22, and the cooling pipeline 51 is provided in the through hole 22.

The heat conducting layer 3 forms a heat exchange effect with the projector controller 2 , which can enhance the cooling effect on the projector controller 2 .

[0039] In one possible implementation, see Figures 1 to 4 The vehicle-mounted projector also includes a first temperature sensor 23 arranged on the projector controller 2.

[0040] Compared with the prior art, the vehicle-mounted projector provided in the embodiment of the present application utilizes a cooling pipe 51 connected to an existing vehicle-mounted evaporator in the vehicle to cool the projector controller 2. The cooling pipe 51 contains a refrigerant, and the cooling pipe 51 extends to the inside of the mounting shell 1. The cooling part 54 is in direct contact with the projector controller 2 to achieve heat dissipation and cooling of the projector controller 2. The vehicle-mounted evaporator can be used to achieve heat exchange with the projector controller 2 to achieve a cooling effect on the projector controller 2, thereby reducing the space occupied by the structure and improving the integrity of the entire vehicle layout.

[0041] The utility model also provides a vehicle, the vehicle includes a vehicle-mounted projector and a vehicle-mounted refrigerator 4 arranged adjacent to the vehicle-mounted projector, the vehicle-mounted refrigerator 4 includes a refrigerator body 41, a cold storage chamber 42, and a refrigerator compressor 43, a refrigerator condenser 44 and a refrigerator evaporator 45 connected in sequence, the cold storage chamber 42, the refrigerator compressor 43, the refrigerator condenser 44 and the refrigerator evaporator 45 are all arranged in the refrigerator body 41, the refrigerator compressor 43 is connected to the refrigerator condenser 44 through a first pipeline 52, the refrigerator condenser 44 is connected to the refrigerator evaporator 45 through a second pipeline 53, the refrigerator evaporator 45 is connected to the refrigerator compressor 43 through a cooling pipeline 51, the cooling part 54 is arranged on the cooling pipeline 51, and the vehicle-mounted evaporator is the refrigerator evaporator 45.

[0042] In this embodiment, the refrigerator evaporator 45 is used as the vehicle-mounted evaporator. The refrigerant medium in the refrigerator evaporator 45 (that is, the vehicle-mounted evaporator) is transported to the cooling pipeline 51. The cooling pipeline 51 uses the cooling part 54 to cool the projector controller 2, thereby avoiding the cumbersome structure caused by the additional installation of a cooling fan in the installation shell 1, and at the same time avoiding the generation of noise, reducing the structural volume of the vehicle-mounted projector, and improving the integrity of the vehicle layout.

[0043] In this embodiment, the refrigerator evaporator 45 is arranged adjacent to the cold storage room 42, and both are arranged in the refrigerator body 41. The refrigerator evaporator 45 is used to apply the refrigeration effect to the cold storage room 42, so that the inside of the cold storage room 42 is cooled down to form a low-temperature preservation effect for the stored items.

[0044] For details, see Figure 1 , Figure 2 and Figure 4 The refrigerator compressor 43, the refrigerator condenser 44 and the refrigerator evaporator 45 are connected in sequence through the first pipeline 52, the second pipeline 53 and the cooling pipeline 51 to form a closed-loop structure to achieve effective transmission of the refrigerant, and finally achieve the cooling effect of the refrigerator evaporator 45 on the refrigerating chamber 42 to ensure the storage function of the refrigerating chamber 42.

[0045] The above structure, on the basis of satisfying the cooling effect on the refrigerating chamber 42, introduces the cooling pipeline 51 into the mounting shell 1, utilizes the cooling part 54 to contact the mounting shell 1, realizes the heat exchange effect with the projector controller 2, ensures the cooling effect on the projector controller 2, realizes the full utilization of energy, simplifies the layout structure in the vehicle, makes the overall layout of the vehicle more integrated, and realizes the effective cooling of the projector controller 2.

[0046] As a parallel embodiment, the side wall of the refrigerator evaporator 45 can be directly in contact with the side wall of the projector controller 2, which is convenient for shortening the length of the cooling pipe 51. The refrigerator evaporator 45 absorbs heat and cools the projector controller 2, thereby enhancing the cooling effect on the projector controller 2. At this time, the refrigerator body 41 and the mounting shell 1 can adopt an integrally formed structure, and the two are interconnected, which is convenient for structural layout, helps to improve the utilization efficiency of space, and improves the integrity of vehicle layout.

[0047] The above arrangement, without substantially changing the structure of the vehicle refrigerator 4, utilizes the refrigerator evaporator 45 (that is, the vehicle evaporator) of the vehicle refrigerator 4 to perform heat exchange with the projector controller 2, thereby achieving a cooling effect on the projector controller 2, reducing the space occupied by the structure, and improving the integrity of the entire vehicle layout.

[0048] For some examples, see Figures 1 to 4 The vehicle further includes a refrigeration controller 47, which is electrically connected to the refrigerator compressor 43 and is used to send a start / stop control instruction to the refrigerator compressor 43. The refrigeration controller 47 can directly send a start / stop control instruction to the refrigerator compressor 43, thereby controlling the working condition of the refrigerator compressor 43 to meet the refrigeration demand of the refrigeration chamber 42 and the cooling and heat dissipation demand of the installation housing 1.

[0050] In this embodiment, the second temperature sensor 46 is used to monitor the internal temperature of the refrigerator chamber 42, so as to adjust the refrigeration capacity of the refrigerator evaporator 45 in real time according to the internal temperature of the refrigerator chamber 42. The second temperature sensor 46 is electrically connected to the refrigeration controller 47, and can send the second temperature parameter in the refrigerator chamber 42 to the refrigeration controller 47 in real time, so that the refrigeration controller 47 can make a judgment according to the prediction program, and then send a second control instruction to the second control valve to adjust the refrigeration capacity of the refrigerator evaporator 45 to meet the refrigeration demand of the refrigerator chamber 42 for storage.

[0051] The refrigerator body 41 and the mounting housing 1 may be formed in one piece or in a separate piece. Figure 4 The vehicle projector is arranged on the top of the vehicle refrigerator 4 , and the cooling pipe 51 passes through the top wall of the refrigerator body 41 and the bottom wall of the mounting shell 1 , and contacts the rear side wall of the projector controller 2 .

[0052] In this embodiment, the vehicle-mounted projector is located at the top of the vehicle-mounted refrigerator 4, and the cooling pipe 51 passes through the top wall of the refrigerator body 41 and the bottom wall of the mounting shell 1 from bottom to top, extending to contact the rear side wall of the projector controller 2 to achieve cooling of the projector controller 2.
