According to the technical scheme, the air inlet assembly 10 is arranged, the passenger cabin 52 is communicated with the vehicle trunk 53 through the air inlet pipeline 11 in the air inlet assembly 10, when an air draft member connected with the air inlet pipeline 11 works, air in the passenger cabin 52 can be sucked to the vehicle trunk 53, the air draft assembly 20 is arranged in the vehicle trunk 53, and the air draft member 21 in the air draft assembly 20 exhausts the air in the vehicle trunk 53 to the outside of a vehicle through an air exhaust hole; thereby forming a convective heat transfer air flow path within the vehicle trunk 53 based on the co-operation of the air intake assembly 10 and the air exhaust assembly 20, thereby improving the heat dissipation efficiency of the vehicle trunk 53.

Further, after the vehicle 500 starts air conditioning and cooling, the air in the passenger compartment 52 is cooled and cooled, and then the cool air sucked into the vehicle trunk 53 has a better heat exchange effect, so that the heat dissipation efficiency of the vehicle trunk 53 can be further improved.

Therefore, the technical scheme is particularly suitable for the vehicle 500 with the air conditioning and refrigerating mode, and cold air is prepared by the vehicle air conditioner of the vehicle 500. The vehicle 500 may be of a type of vehicle 500 provided with only a front air outlet or with both a front air outlet and a rear air outlet, but in either type, after the air conditioner of the vehicle 500 is turned on, the temperature of the air in the rear exhaust of the vehicle can be reduced due to the connectivity between the front and rear rows of the vehicle 500.

Referring to fig. 1 and 2, in some embodiments, the air intake duct 11 includes an air intake 111 and an air outlet 112, the air intake 111 is disposed under the rear seat 51 of the vehicle 500, the air outlet 112 is disposed at the front portion of the trunk 53 near the rear seat 51, and the air exhaust hole and the air exhaust member 21 are disposed at the rear portion of the trunk 53 far from the rear seat 51.

It will be appreciated that the two ends of the air intake duct 11 may extend to the space of the passenger compartment 52 and to the space of the vehicle trunk 53, respectively, and thus the duct length of the air intake duct 11 may be set according to actual requirements. When the air inlet 111 is disposed under the rear seat 51 of the vehicle 500, the air inlet 111 can be hidden by the rear seat 51 to ensure the simplicity of the rear air space of the vehicle. And when the air outlet 112 is disposed at the front of the vehicle trunk 53 and the exhaust hole and the exhaust member 21 are disposed at the tail of the vehicle trunk 53, the airflow path formed in the vehicle trunk 53 has a maximum coverage space, so that heat exchange can be rapidly realized in the vehicle trunk 53, and the heat dissipation efficiency in the vehicle trunk 53 is further improved.

Referring to fig. 1 and 2, in some embodiments, the air intake duct 11 includes a main duct 110 and at least two sub-ducts 120 connected to the main duct 110, the main duct 110 communicates the passenger cabin 52 with the vehicle trunk 53, each sub-duct 120 extends to different heat generating areas in the vehicle trunk 53, the air draft member is disposed on the main duct 110 and/or the sub-duct 120, the free end of the main duct 110 is provided with an air inlet 111, and the free end of each sub-duct 120 is provided with an air outlet 112.

The number of the sub-ducts 120 may be two, three, four or more, and the number of the sub-ducts 120 is the number of the air outlets 112, which is not limited herein. Further, the main duct 110 and the sub-duct 120 may be configured based on the layout of the components in the trunk 53, for example, the sub-duct 120 may bend through a gap formed between the components of the trunk 53 to configure the air outlet 112 in a heat generating area in the trunk 53, i.e. the arrangement area of the heat generating components 54. In this way, the air outlets 112 of the different sub-pipes 120 extend to different heating areas in the vehicle trunk 53, so that the heat exchange speed of the heating areas in the vehicle trunk 53 can be increased in a targeted manner, and the heat dissipation efficiency of the vehicle trunk 53 is further improved, and when cold air is injected into the vehicle trunk 53 through the air outlets 112, the heat dissipation efficiency is higher.

Optionally, when the air extracting member is disposed on the main pipe 110, only one air extracting member may be disposed, and air entering through the air inlet 111 of the main pipe 110 flows along the main pipe 110 and is split when encountering the sub-pipes 120, so as to be discharged from the air outlet 112 of each sub-pipe 120; when the air draft members are disposed in the sub-pipes 120, each sub-pipe 120 is correspondingly provided with an air draft member, and air is exhausted from the air outlet 112 of the corresponding sub-pipe 120 through the operation of each air draft member.

Optionally, the number of the subducting pipes 120 connected to the main duct 110 is two, including a first subducting pipe and a second subducting pipe, and the main duct 110 is connected to the first subducting pipe and the second subducting pipe through the tee joint pipe 130 to form a T-shaped air intake duct 11. The first sub-pipe and the second sub-pipe are respectively extended and arranged in two side spaces of the vehicle trunk 53 to radiate heat of the heat generating components 54 arranged in the two side spaces.

In some embodiments, a filter screen (not shown in the drawings) is provided at the air inlet 111 of the air inlet duct 11. Thus, by arranging the filter screen at the air inlet 111 of the air inlet pipe 11, the problem of blockage of the air inlet pipe 11 caused by the entry of impurities such as dust in the passenger cabin 52 into the air inlet pipe 11 from the air inlet 111 can be prevented, and the smoothness of the air inlet pipe 11 can be further ensured.

In some embodiments, the air inlet 111 of the air intake duct 11 is directly opposite the air conditioner air outlet provided in the passenger compartment 52. In general, the air-conditioning outlet of the rear row of the vehicle is almost the same as the rear seat 51 in height, and the air temperature at the air-conditioning outlet is the lowest. In this way, the air inlet 111 of the air intake duct 11 is opposite to the air-conditioning air outlet provided in the passenger compartment 52, and the air intake assembly 10 can suck air having a lower temperature when the cooling air conditioner of the vehicle 500 is turned on, thereby improving the heat dissipation efficiency of the heat generating components 54 in the trunk 53 of the vehicle.

In some embodiments, an air outlet pipe 13 is disposed at the air outlet 112, and the air extracting member includes an air extracting fan disposed on the air outlet pipe 13. The exhaust fan and the air outlet pipe fitting 13 are common components for the exhaust pipe arrangement, and are not described in detail. In this way, the exhaust fan is arranged, and the air in the passenger cabin 52 is sucked to the vehicle trunk 53 through the exhaust fan, so that the structure is simple, and the cost is low; the air outlet pipe fitting 13 can be used for installing and fixing the exhaust fan and protecting the exhaust fan.

In some embodiments, the number of air intake assemblies 10 is several, and the air intake ducts 11 in the several air intake assemblies 10 are disposed between the passenger compartment 52 and the vehicle trunk 53 at intervals.

In this embodiment, the air intake assemblies 10 do not interfere with each other, a plurality of air intake assemblies 10 are provided, i.e. a plurality of air intake pipes 11 are provided, and each air intake pipe 11 may be arranged below the rear seat 51 at intervals in a row when in arrangement, or the main pipe 110 is bent and extended, so that the air inlets 111 of each main pipe 110 are concentrated at the corresponding positions of the rear air discharge and air outlet. In this way, when the plurality of air intake assemblies 10 are arranged, and the air intake pipes 11 in the plurality of air intake assemblies 10 are arranged between the passenger cabin 52 and the vehicle trunk 53 at intervals, the plurality of air intake assemblies 10 can operate simultaneously to increase the passage of air in the passenger cabin 52 into the vehicle trunk 53, that is, the air conveying efficiency of the passenger cabin of the vehicle 500 to the vehicle trunk 53 is improved, and the heat dissipation efficiency of the vehicle trunk 53 is further improved.

In some embodiments, a temperature detection unit (not shown in the drawings) is disposed in the vehicle trunk 53, and the air extraction member is provided with a plurality of operation gears, and the air extraction member can perform gear adjustment according to the feedback temperature of the temperature detection unit.

It will be appreciated that the heat sink is provided with a corresponding control unit that, upon powering up the vehicle 500, activates the heat sink while the trunk control apparatus is operated. The temperature detection unit in the heat dissipating device detects the temperature in the vehicle tail box 53 in real time, and controls the air draft member to perform corresponding operation gear adjustment when the temperature reaches different sections.

The exhaust element is provided with three adjustment gears, namely a low-speed gear, a medium-speed gear and a high-speed gear. The higher the gear, the stronger the air sucking ability to the inside of the vehicle passenger compartment 52, and the farther the air supply distance of the air discharged through the air outlet 112, the higher the heat radiation efficiency, with the same duct cross-sectional area.

Optionally, the detected temperature corresponding to the low rotation speed gear is in a temperature interval not higher than 45 ℃, the detected temperature corresponding to the medium rotation speed gear is in a temperature interval of 46-60 ℃, and the detected temperature corresponding to the high rotation speed gear is in an interval of 61-80 ℃; then, when detecting that the temperature in the vehicle tail box 53 reaches different temperature intervals, the temperature detection unit feeds back to the control unit and can control the air suction member to adjust to the rotational speed gear of the air suction member corresponding to the current temperature interval.

Thus, a feedback regulation mechanism of temperature detection and the gear of the air draft member is established, when the temperature in the vehicle tail box 53 is lower, the air draft member can work at a low rotation speed gear, and when the temperature in the vehicle tail box 53 is higher, the air draft member can be correspondingly regulated to a higher rotation speed, so that not only can the energy-saving effect be achieved, but also the supply of air in the vehicle tail box 53 can be ensured, and the heat dissipation of the vehicle tail box 53 is realized.

When the air draft member works, the rotating speed of the air draft member is arranged in a corresponding section so as to meet the noise requirement in the vehicle, and a comfortable riding environment is provided for drivers and passengers.

In some embodiments, a temperature detecting unit is disposed in the vehicle trunk 53, and a flow rate adjusting unit (not shown in the drawings) for controlling the flow rate of air is disposed in the air intake duct 11, and the flow rate adjusting unit may perform flow rate adjustment according to a feedback temperature of the temperature detecting unit.

In this embodiment, the flow rate adjusting unit may be a flow rate adjusting valve for adjusting the flow rate of air in the pipe. A control unit may be provided to activate the heat sink while the trunk control apparatus is being operated after the vehicle 500 is powered up. The temperature detection unit in the heat sink detects the temperature in the vehicle tail box 53 in real time, and controls the flow rate regulating valve to perform corresponding air flow rate regulation when the detected temperature reaches different temperature intervals.

Similar to the feedback adjustment mechanism for establishing the temperature detection and the air extraction member shift position, the feedback adjustment mechanism for temperature detection and flow control is established in this embodiment. The flow regulating valve is provided with three regulating gears, namely a low flow control gear, a medium flow control gear and a high flow control gear. The higher the gear is, the larger the cross-sectional area of the pipeline at the flow regulating valve is, the larger the air quantity discharged through the air outlet 112 is, and the better the heat dissipation effect is. Furthermore, when the temperature in the vehicle trunk is not high, particularly when the vehicle is cooled by an air conditioner, the flow regulating valve can be regulated to be in a low flow control gear for air supply, so that the cold air inlet quantity in the vehicle trunk is reduced, and the purpose of saving energy is achieved while the heat dissipation requirement is met.

Optionally, the detected temperature corresponding to the low rotation speed gear is in a temperature interval not higher than 45 ℃, the detected temperature corresponding to the medium rotation speed gear is in a temperature interval of 46-60 ℃, and the detected temperature corresponding to the high rotation speed gear is in an interval of 61-80 ℃; then, when the temperature detecting unit detects that the temperature in the vehicle tail box 53 reaches a different temperature interval, the temperature detecting unit feeds back to the control unit and the flow regulating valve can be controlled by the control unit to be regulated to a flow control gear corresponding to the current temperature interval.

Typically, a flow regulating unit is provided on the main conduit 110 to control the amount of air flow into the vehicle trunk 53.

In some embodiments, the above air extraction member gear adjustment and flow adjustment unit may be simultaneously disposed in the heat dissipation device, and the heat dissipation device further includes a control unit and a temperature detection unit that are provided, based on the temperature in the vehicle trunk 53 detected by the temperature detection unit, the air extraction member gear and the flow adjustment gear are cooperatively adjusted to achieve more excellent air injection performance.

Optionally, the above temperature monitoring unit is a temperature sensor.

In some embodiments, the exhaust assembly 20 further includes a fixing bracket 22, the fixing bracket 22 being disposed at the exhaust hole, and the exhaust member 21 includes an exhaust fan mounted through the fixing bracket 22. The exhaust fan and the fixing support 22 thereof are common components for exhaust arrangement, and will not be described again. Thus, the exhaust fan is arranged, hot air in the tail box 53 of the vehicle is discharged to the outside of the vehicle through the exhaust fan, and the structure is simple and the cost is low; the fixing support 22 can also protect the exhaust fan while installing and fixing the exhaust fan.

It should be noted that, to increase the exhaust efficiency of the air in the vehicle trunk 53, the exhaust assembly 20 may be provided with multiple groups. The exhaust assembly 20 is provided with two sets of exhaust assemblies 20, and the two sets of exhaust assemblies 20 are arranged on two sides of the tail box body close to the tail space, and the two sets of exhaust assemblies 20 are arranged corresponding to the exhaust holes.
