Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a heat dissipation system for a vehicle-mounted work cabin. More specifically, it relates to a system that integrates solar power supply and uses side forced ventilation to dissipate heat from a closed or semi-closed work cabin installed on a vehicle, as well as its independent power supply structure. Background Technology

[0002] Vehicle-mounted drone operating cabins (such as those integrated into the top cover of a pickup truck bed or in a separate compartment) typically integrate various electronic devices, including the drone's housing, battery charging system, edge computing unit, and power module. These devices generate a significant amount of heat during operation.

[0003] When performing tasks, vehicles may be parked for extended periods in high-temperature outdoor environments (such as under direct sunlight in summer) or in areas with poor air circulation. Because the work compartment is relatively enclosed, heat can easily accumulate inside, causing a rapid increase in interior temperature.

[0004] Excessively high cabin temperatures can cause serious damage to the delicate electronic equipment inside, especially the drone's battery, nest control system, and the drone itself (if parked inside the nest). For example:

[0005] 1. Reduces battery charging efficiency and lifespan, and may even lead to the risk of thermal runaway.

[0006] 2. It can lead to a decline in the performance of electronic components, unstable operation, or even permanent damage.

[0007] 3. It affects the accuracy of drone sensors.

[0008] 4. Accelerates material aging.

[0009] Existing vehicle modifications may overlook the issue of active cooling in the work compartment, or rely on simple top openings for natural ventilation, which has limited effectiveness. Some fan-based cooling solutions may have problems such as unreasonable air duct design (e.g., close proximity of air inlets and outlets leading to hot air recirculation), insufficient fan waterproofing, or dependence on the vehicle's main power supply, resulting in insufficient cooling after the vehicle is turned off.

[0010] Especially when the vehicle is parked for an extended period of time with the engine off (such as during mission breaks or overnight parking) but there is still equipment on standby inside the cabin or a need to maintain a suitable temperature (such as battery insulation or heat dissipation), providing continuous, reliable, and energy-efficient heat dissipation capabilities is a challenge. Utility Model Content

[0011] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a side-mounted forced ventilation vehicle-mounted work cabin heat dissipation system with integrated solar power supply, which solves the problem of heat accumulation and excessive temperature inside the vehicle-mounted work cabin when operating in high-temperature environments or under high equipment loads; provides an efficient forced ventilation heat dissipation solution to avoid hot air stagnation and backflow inside the cabin; solves the problem of waterproofing and dustproofing of the cooling fan in outdoor environments (rain, dust); and provides an independent and energy-saving power supply method for the heat dissipation system, so that necessary ventilation and heat dissipation can continue even when the vehicle is turned off and parked.

[0012] This invention features waterproof intake and exhaust fan units on opposite side walls of the work cabin, forming a forced side-intake and side-exhaust air convection channel. Furthermore, the main power source for this cooling system is a flexible solar cell film installed on the vehicle (such as the top of the cab) or the top of the work cabin, which is managed through an independent energy storage and control unit.

[0013] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0014] A side-forced ventilation vehicle-mounted work compartment cooling system with integrated solar power, comprising:

[0015] A work cabin, which is installed on a vehicle and is a closed or semi-closed structure, and is equipped with work equipment.

[0016] An air intake fan is installed on one side wall of the work cabin, and the work cabin has an air intake port for the air intake fan on that side wall.

[0017] An exhaust fan is installed on the opposite side wall of the work cabin from the intake fan, and the work cabin has an exhaust port for the exhaust fan on the opposite side wall. The intake port, intake fan, exhaust fan, and exhaust port form a forced side air intake and side air exhaust convection channel.

[0018] A solar power supply mechanism is installed on the vehicle and electrically connected to the intake and exhaust fans to supply power to them.

[0019] Preferably, both the intake fan and the exhaust fan are high-protection-level axial or centrifugal fans, and the air volume of the exhaust fan is equal to or greater than that of the intake fan.

[0020] Preferably, both the air inlet and the air outlet are provided with protective structures on their exteriors; the protective structure of the air inlet includes rainproof louvers and a dustproof filter, and the protective structure of the air outlet includes rainproof louvers.

[0021] Preferably, the solar power supply mechanism includes a solar cell film, a charge / discharge controller, and an energy storage battery; the solar cell film is installed on the top of the vehicle or work cabin, and the charge / discharge controller is electrically connected to the solar cell film, the energy storage battery, the intake fan, and the exhaust fan, respectively.

[0022] Preferably, the solar power supply mechanism further includes a temperature control unit and a power supply switch; the temperature control unit is electrically connected to the charge / discharge controller and the power supply switch respectively, and the power supply switch is installed on the power supply lines of the charge / discharge controller and the intake fan and the exhaust fan.

[0023] Preferably, the temperature control unit includes a temperature sensor and a temperature controller; the temperature sensor is installed inside the work chamber, and the temperature controller is electrically connected to the temperature sensor and the power supply switch respectively.

[0024] Preferably, the solar power supply mechanism further includes a manual switch for forcibly turning the intake fan and the exhaust fan on or off.

[0025] Preferably, the solar cell film is a flexible structure with redundant configuration, and the solar cell film is pasted or fixed to the top of the vehicle cab, the top of the work compartment, or a surface of the vehicle body with a large solar radiation area and a relatively regular shape.

[0026] Preferably, the work cabin is equipped with a deflector plate for guiding airflow through the heating area.

[0027] Preferably, the operating equipment installed in the operating cabin includes a drone nest and related equipment.

[0028] The beneficial effects of this utility model are:

[0029] The side-forced ventilation vehicle-mounted work compartment heat dissipation system provided by this utility model has the following advantages:

[0030] 1. Highly efficient forced cooling: The forced ventilation method with side intake and side exhaust creates a clear airflow path, which is more efficient than natural ventilation at the top or a single fan. It can effectively reduce the temperature inside the cabin and prevent heat accumulation.

[0031] 2. Enhance equipment reliability and lifespan: By effectively controlling the internal temperature, the system protects the drone's internal components, batteries, control units, and other precision electronic equipment, reducing performance degradation, damage, and shortened lifespan caused by high temperatures.

[0032] 3. Independent and continuous operation: Using solar power and energy storage batteries, the cooling system can work independently and continuously when the vehicle is parked with the engine off, solving the heat dissipation problem when parked for a long time.

[0033] 4. Energy saving and environmental protection: It mainly uses solar energy as an energy source, reducing dependence on the vehicle's main power supply and lowering energy consumption and carbon emissions.

[0034] 5. High protection: It adopts waterproof fans and protective structures, which can adapt to harsh outdoor environments and improve the reliability of the system.

[0035] 6. Flexible layout: Side-mounted fans may be easier to implement on certain vehicle structures than top-mounted fans, and flexible solar films can adapt to different roof shapes. Attached Figure Description

[0041] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model.

[0042] Example 1

[0043] A side-forced ventilation cooling system for a vehicle-mounted work compartment, powered by integrated solar energy, such as... Figures 1-3 As shown, it includes:

[0044] Work compartment 1, which is installed on the vehicle and is a closed or semi-closed structure, and is equipped with work equipment.

[0045] Air intake fan 2 is installed on one side wall of the work chamber 1, and the work chamber 1 has an air intake port for air intake fan 2 on this side wall.

[0046] Exhaust fan 3 is installed on the opposite side wall of the working chamber 1 and the intake fan 2. The working chamber 1 is provided with an exhaust port of exhaust fan 3 on the opposite side wall. The intake port, intake fan 2, exhaust fan 3 and exhaust port form a forced side air intake and side air exhaust convection channel.

[0047] A solar power supply mechanism 4 is installed on the vehicle and electrically connected to the intake fan 2 and the exhaust fan 3 to supply power to them.

[0048] Both the intake fan 2 and the exhaust fan 3 are high-protection-level axial or centrifugal fans, and the air volume of the exhaust fan 3 is equal to or greater than that of the intake fan 2. Both the intake and exhaust ports are equipped with protective structures; the intake port's protective structure includes rainproof louvers and a dust filter, while the exhaust port's protective structure includes rainproof louvers.

[0049] In this embodiment, the work compartment 1 refers to a closed or semi-closed structure installed on a vehicle to accommodate the drone's nest and related equipment. Specifically, in this solution, it is an independent compartment added to the body of a pickup truck.

[0050] For intake fan 2:

[0051] Installation location: Installed on the side wall of the work compartment (e.g., on the left or right side of the vehicle's direction of travel).

[0052] Fan selection: Choose axial or centrifugal fans with high protection ratings (such as IP67 or higher) and good waterproof and dustproof performance. The fan size and airflow should be selected based on the volume of the enclosure and the expected heat dissipation requirements.

[0053] Air inlet protection: The air inlet is equipped with multiple protective structures such as rainproof louvers and dustproof filters to prevent rainwater and sand from entering directly.

[0054] For exhaust fan 3:

[0055] Installation location: Installed on the side wall opposite the intake fan in the work compartment (e.g., on the right or left side in the direction of vehicle travel).

[0056] Fan selection: Same as the intake fan, but select a high-protection-level fan. The exhaust fan's airflow should generally be equal to or slightly greater than the intake fan's airflow to create a slight negative pressure inside the compartment, which helps prevent dust from entering through gaps.

[0057] Vent protection: The outside of the vent is also equipped with rainproof louvers and other structures.

[0058] like Figure 1As shown, the solar power supply mechanism 4 includes a solar cell film 41, a charge / discharge controller 42, and an energy storage battery 43; the solar cell film 41 is installed on the top of the vehicle or the work cabin 1, and the charge / discharge controller 42 is electrically connected to the solar cell film 41, the energy storage battery 43, the intake fan 2, and the exhaust fan 3, respectively.

[0059] In this embodiment, for solar cell film 41:

[0060] Installation location: Attach or fix to the top of the vehicle's cab, work compartment, or other relatively regular-shaped surfaces on the vehicle body that have a large area exposed to sunlight. The flexible design allows for better conforming to the curved surface of the roof.

[0061] Type and Power: High-efficiency flexible solar cells (such as CIGS, amorphous silicon, etc.) are selected. The power is configured based on the power consumption of the cooling fan and control unit, as well as the expected sunlight conditions, and a certain amount of power redundancy can be considered to cope with insufficient sunlight. (Optional supplement: To improve power supply reliability, multiple solar cell films can be connected in parallel or redundant power supply can be achieved through specific circuit management.)

[0062] For charge / discharge controller 42:

[0063] Functions: It is responsible for managing the output of solar panels, intelligently charging energy storage batteries (such as MPPT maximum power point tracking), preventing overcharging and over-discharging, and providing load output to power subsequent devices.

[0064] For energy storage battery 43:

[0065] Type: Lithium batteries (such as lithium iron phosphate) or other energy storage batteries suitable for the vehicle environment can be selected.

[0066] Capacity: The capacity must be sufficient to support the cooling fan to run continuously for a certain period of time when there is no sunlight or insufficient sunlight (such as at night or on rainy days) (set according to needs, such as supporting cooling for several hours at night).

[0067] like Figure 1 As shown, the solar power supply mechanism 4 also includes a temperature control unit 44 and a power switch 45; the temperature control unit 44 is electrically connected to the charge / discharge controller 42 and the power switch 45 respectively, and the power switch 45 is located on the power supply lines between the charge / discharge controller 42 and the intake fan 2 and the exhaust fan 3. The temperature control unit 44 includes a temperature sensor 441 and a temperature controller 442; the temperature sensor 441 is installed inside the operating chamber 1, and the temperature controller 442 is electrically connected to the temperature sensor 441 and the power switch 45 respectively.

[0068] In this embodiment, for the optional intelligent temperature control unit 44:

[0069] Composition: Includes a temperature sensor installed in a key location inside the cabin (such as near heat-generating equipment or on the top of the cabin) and a temperature controller (which can be a standalone MCU or integrated into other vehicle control units).

[0070] Function: Real-time monitoring of cabin temperature. When the temperature exceeds a preset threshold, the fan automatically starts to dissipate heat; when the temperature drops to a safe range, the fan automatically stops or reduces its speed to save energy. The controller can also adjust the heat dissipation strategy based on solar power supply and battery charge levels.

[0071] Electrical connections and wiring: Connect the solar cell film, charge / discharge controller, energy storage battery, temperature control unit, and fan, such as... Figure 1 As shown.

[0072] Working principle:

[0073] During the day when there is sunlight, the flexible solar film generates electricity, which charges the energy storage battery through the charge and discharge controller and can directly drive the fan (if the temperature requires).

[0074] When the cabin temperature sensor detects that the temperature exceeds the threshold, the (intelligent) temperature control unit starts the intake and exhaust fans.

[0075] The intake fan draws in relatively cool outside air from one side of the vehicle.

[0076] Air flows inside the cabin, passing through heating equipment and absorbing heat.

[0077] The heated air is forced out of the cabin by an exhaust fan on the other side.

[0078] It creates a continuous lateral airflow that efficiently removes heat from the cabin.

[0079] At night or on rainy days, the energy storage battery powers the fan and control unit, ensuring necessary heat dissipation.

[0080] When the cabin temperature drops below the safe threshold, the fan will automatically stop or reduce its speed.

[0081] Example 2

[0082] In this embodiment:

[0083] Vehicle: Taking pickup trucks as an example, this is implemented on the hard top cover (as a work compartment) installed in the rear bed.

[0084] Fans: Two 120mm DC axial fans with IP68 rating are installed in corresponding positions on the left and right sides of the top cover (for example, the appropriate brand and model can be selected according to the actual heat dissipation needs). The intake fan has a replaceable dust filter and rainproof louvers, and the exhaust fan has rainproof louvers.

[0085] Solar film: A flexible CIGS solar cell film with appropriate power is attached to the top of the pickup truck cab.

[0086] Control and Energy Storage: A 20A MPPT solar charge / discharge controller is used, connected to a 40Ah battery. The temperature controller has a built-in temperature detection interface, which connects to an internal temperature sensor, and sets a start threshold of, for example, 40°C, and a stop threshold of, for example, 30°C.

[0087] Airflow duct (optional): Simple deflectors can be added inside the cabin to guide airflow more effectively through the main heat-generating areas (such as the heat sink of the charging module).

[0088] Wiring: All external wiring uses waterproof connectors and weather-resistant cables.

[0089] Example 3

[0090] In this embodiment:

[0091] 1. Power supply section:

[0092] The DC power generated by the solar cell film is input to the PV input terminal of the solar charge / discharge controller.

[0093] The charge / discharge controller manages the charging of the energy storage battery and is connected to the BAT (battery) terminal. It is preferable to include a fuse or circuit breaker between the battery positive terminal and the controller for safety.

[0094] The charge / discharge controller provides a LOAD output for powering downstream devices. This output typically includes undervoltage protection.

[0095] 2. Control and Execution Section:

[0096] The intelligent temperature control unit (such as a microcontroller (MCU) or a dedicated temperature controller) obtains power from the LOAD output of the charge / discharge controller.

[0097] The temperature sensor sends the detected cabin temperature signal to the intelligent temperature control unit.

[0098] The intelligent temperature control unit outputs a control signal to the relay or MOSFET switch based on its internal logic (such as the temperature exceeding a threshold).

[0099] The relay / MOSFET switch also draws main power from the LOAD output of the charge / discharge controller (for switching to the fan).

[0100] When a control signal is received from the temperature control unit, the relay / MOSFET switch closes, connecting the power supply at the LOAD output to the intake fan and the exhaust fan (the two fans are usually connected in parallel).

[0101] 3. Optional manual control:

[0102] The solar power supply mechanism 4 also includes a manual switch 46 for forcibly turning the intake fan 2 and the exhaust fan 3 on or off.

[0103] In this embodiment, a manual switch can be added to force the fan to turn on or off. The simplest connection is to connect it in parallel to the output contacts of the relay / MOSFET, or in series with the power supply line to the fan. It can also be designed to control the power supply of the temperature control unit or the relay.

[0104] The embodiments of this utility model have been described in detail above, but this utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalents or substitutions are all included within the scope defined by the claims of this utility model.
