[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0047] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0049] In the related technologies, for example, HUD display products not only have high heat dissipation requirements, but also have strict requirements on ambient temperature for their normal operation. When HUD display products are used during the day, due to the strong ambient light, in order to ensure the projection picture effect, the display brightness needs to be increased, but correspondingly, it will also lead to increased power consumption and heat generation of the product, which brings huge challenges to product heat dissipation. When HUD display products are used at lower or higher ambient temperatures, due to exceeding the applicable operating temperature range of the product, the product may not start normally or the working performance may be greatly reduced, and even seriously affect the service life of the product.

The air inlet section is usually provided with an air source door ( Figure 1 The air source door is used to determine the source, proportion and air volume of the conditioned air. The air source door 267 can be, for example, a blower, which is used to introduce air into the air distribution chamber 26. The air mixing section is provided with the evaporator 268 of the refrigeration system 21, the heater core 269 of the heater system 22, and the air mixing door 270. The refrigerant in the evaporator 268 absorbs heat by evaporation, the heater core 269 can heat the air, and the air mixing door 270 can adjust the mixing ratio of cold and hot air. The distribution section is used to transport the air adjusted by the air mixing section to the target position of the vehicle, such as the instrument panel air outlet, the armrest box air outlet, etc., to achieve air conditioning in the vehicle.

[0068] like Figure 1 As shown, in an embodiment of the present application, according to the pressure and temperature characteristics of the air distribution chamber 26 in different areas, the air distribution chamber 26 may include a normal temperature negative pressure zone 261, a normal temperature positive pressure zone 262 and a mixing positive pressure zone 263 that are connected in sequence, wherein the normal temperature negative pressure zone 261 is located on the air inlet side of the fan 267, the normal temperature positive pressure zone 262 is located on the air outlet side of the fan 267, the evaporator 268, the warm air core 269 and the mixing door 270 are arranged in sequence, and a warm air positive pressure sub-zone 264, a cold air positive pressure sub-zone 265 and a mixing air positive pressure sub-zone 266 can be formed in the mixing positive pressure zone 263.

[0069] In the embodiment of the present application, the specific structural form of the air duct structure 30 is not limited. For example, the air duct structure 30 can be a soft pipe, a sheet metal pipe, or a channel enclosed and defined by vehicle components. Figure 1 As shown, the air duct structure 30 can be designed to include a plurality of air duct components separated from each other ( Figure 1 The middle air duct structure 30 includes two air duct components, namely a first air duct component 310 and a second air duct component 320, and can also be designed to include a trunk section 321 and a branch section 322. Depending on the specific structural design of the air duct structure 30, one or more dampers 40 can be provided on the air duct structure 30. The embodiment of the present application does not limit the specific number of dampers 40. By controlling the working state of at least one damper 40, the air duct structure 30 can be placed in a variety of on-off states, and the amount of air in the air duct structure 30 can be adjusted.

[0070] According to the technical solution of the embodiment of the present application, the air duct structure 30 is arranged between at least one of the normal temperature negative pressure zone 261, the normal temperature positive pressure zone 262, the warm air positive pressure sub-zone 264, the cold air positive pressure sub-zone 265 and the mixed air positive pressure sub-zone 266 and the electronic device 101 of the electronic device 10, and the control device 50 can control the working state of the at least one damper 40 based on the working environment temperature of the electronic device 10, so that the air duct structure 30 can be connected between at least one of the normal temperature negative pressure zone 261, the normal temperature positive pressure zone 262, the warm air positive pressure sub-zone 264, the cold air positive pressure sub-zone 265 and the mixed air positive pressure sub-zone 266 and the electronic device 101 of the electronic device 10. In this way, the HVAC system 20 configured by the vehicle itself can be used to perform thermal management on the electronic device 10 to meet the thermal management requirements of the electronic device 10 and improve its working reliability.

[0071] For example, for an electronic device 10 including the first type electronic device 101a, the first type electronic device 101a can be heated and cooled by the HVAC system 20 of the vehicle itself through the corresponding design of the air duct structure 30 and the damper 40.

[0072] For example, for the electronic device 10 including the second type electronic device 101 b described above, the second type electronic device 101 b can be cooled by the HVAC system 20 of the vehicle itself through the corresponding design of the air duct structure 30 and the damper 40 .

[0073] In some related technologies, electronic devices naturally dissipate heat through metal casings, and their heat dissipation capacity is limited, resulting in relatively limited application occasions. In other related technologies, electronic devices are equipped with heat dissipation devices such as fans or semiconductor cooling sheets for electronic devices with heat dissipation requirements, and heating devices such as heating resistors for electronic devices with heating requirements. Not only are the structures complex, the working noise is loud, the energy consumption is high, the production cost is high, the working reliability is difficult to guarantee, but the electronic devices are also larger in size.

[0074] In some embodiments of the present application, based on the above-mentioned design of the thermal management solution for the electronic device 10, the electronic device 10 may not be provided with a heat dissipation device and a heating device. Therefore, compared with the related technology, it can not only meet the thermal management requirements of the electronic device, but also simplify the structure of the electronic device, reduce its operating noise, improve its operating reliability, save energy consumption, reduce production costs, and reduce the product volume of the electronic device.

[0075] like Figure 1As shown, in some embodiments of the present application, the electronic device 10 may include a housing 102, and the housing 102 has a vent 103, which may be, for example, a vent hole or a ventilation grille. The electronic device 101 is disposed in the housing 102, and at least one vent (two vents are shown in the figure) of the duct structure 30 may extend into the housing 102. For example, the duct structure 30 may extend into the housing 102 through an opening correspondingly provided on the housing 102. Inside the housing 102, an internal duct (not shown in the figure) may be designed based on the layout of the electronic device 101 and other structural parts, so that an airflow circulation path may be formed between the air distribution chamber 26, the duct structure 30, the internal duct of the electronic device 10, the vent 103, and the external environment of the housing 102.

[0076] like Figure 1 As shown, in some embodiments of the present application, the electronic device 10 may include a heat exchange device 104, which is used to perform heat exchange with the electronic device 101, wherein at least one air outlet of the air duct structure 30 may extend to be opposite to the heat exchange device 104. The heat exchange device 104 may be, for example, a heat sink fin or a microchannel heat exchanger, etc., but is not limited to these structures. At least one air outlet of the air duct structure 30 is opposite to the heat exchange device 104, so that the heat exchange between the electronic device 101 and the heat exchange device 104 can be accelerated by airflow, thereby improving the efficiency of heat exchange. In these embodiments, the electronic device 10 may or may not include a housing 102.

[0077] In the embodiment of the present application, a corresponding control strategy can be designed for the control device 50 based on the thermal management requirements of the electronic device 10 .

[0078] For example, in some embodiments, the electronic device 10 includes a first type of electronic device 101a having a heating demand and a heat dissipation demand. For this application scenario, the control device 50 can be configured to: in response to the working environment temperature of the electronic device 10 meeting the heating start condition, control the at least one damper 40 to connect the air duct structure 30 between the warm air positive pressure sub-zone 264 or the mixed air positive pressure sub-zone 266 and the first type of electronic device 101a. The heating start condition can be determined based on experience, or based on the working applicable temperature range of the first type of electronic device 101a. In some embodiments, the heating start condition is set to the working environment temperature of the electronic device 10 being less than the minimum working temperature threshold of the first type of electronic device 101a. In these embodiments, the warm air blown out of the warm air positive pressure sub-zone 264 or the mixed air positive pressure sub-zone 266 can be used to heat the first type of electronic device 101a.

[0079] For example, in some other embodiments, the electronic device 10 includes a first type of electronic device 101a with heating requirements and heat dissipation requirements and / or a second type of electronic device 101b with heat dissipation requirements but no heating requirements. For this application scenario, the control device 50 can be configured to: in response to the working environment temperature of the electronic device 10 meeting the first heat dissipation start condition, control the at least one damper 40 to connect the air duct structure 30 between the normal temperature negative pressure zone 261 and the above-mentioned electronic devices 101 with heat dissipation requirements. The first heat dissipation start condition can be determined based on experience or based on the working applicable temperature range of the electronic device 101. For example, in some embodiments, the first heat dissipation start condition is set as the working environment temperature of the electronic device 10 is not less than the minimum working temperature threshold of the first type of electronic device 101a. In these embodiments, the normal temperature negative pressure zone 261 can be used to remove the heat of the electronic device 101 by exhausting air, thereby dissipating the heat of the electronic device 101.

[0080] For example, in some other embodiments, the electronic device 10 includes a first type of electronic device 101a with heating requirements and heat dissipation requirements and / or a second type of electronic device 101b with heat dissipation requirements but no heating requirements. For this application scenario, the control device 50 can be configured to: in response to the working environment temperature of the electronic device 10 meeting the first heat dissipation start condition, control the at least one damper 40 to connect the air duct structure 30 between the normal temperature positive pressure zone 262 and the above-mentioned electronic devices 101 with heat dissipation requirements. Similarly, the first heat dissipation start condition can be determined based on experience or based on the applicable working temperature range of the electronic device 101. In these embodiments, the normal temperature positive pressure zone 262 can be used to blow normal temperature wind to take away the heat of the electronic device 101, thereby dissipating the heat of the electronic device 10.

[0081] For example, in some further embodiments, the electronic device 10 includes a first type of electronic device 101a with heating demand and heat dissipation demand and / or a second type of electronic device 101b with heat dissipation demand but no heating demand. For this application scenario, the control device 50 can be configured to: in response to the working environment temperature of the electronic device 10 meeting the second heat dissipation start-up condition, control the at least one damper 40 to connect the air duct structure 30 between the cold air positive pressure sub-zone 265 and the above-mentioned electronic devices 101 with heat dissipation demand. The second heat dissipation start-up condition may be the same as or different from the first heat dissipation start-up condition. In some embodiments, the second heat dissipation start-up condition may be that the working environment temperature of the electronic device 10 is higher than the maximum working temperature threshold of the first type of electronic device 101a. In these embodiments, the cold air positive pressure sub-zone 265 can be used to take away the heat of the electronic device 101 by blowing cold air to the electronic device 101, thereby dissipating the heat of the electronic device 101.

[0082] For the electronic device 10 including the first type electronic device 101a and the second type electronic device 101b, the control device 50 can configure the above-mentioned multiple control strategies to perform corresponding control according to different thermal management requirements.
