Description

Technical Field

[0001] This utility model relates to a heat dissipation system, specifically an intelligent heat dissipation system for a full-power power take-off unit in a commercial vehicle. Background Technology

[0002] Existing full-power PTO cooling systems for commercial vehicles have several shortcomings. When operating at full load, the PTO outputs significant power, generating considerable heat over time. This heat is transferred to the engine, triggering an engine overheating alarm and preventing further operation. The vehicle must then be turned off and allowed to cool down before resuming operation, reducing both efficiency and the lifespan of the PTO. Utility Model Content

[0003] This invention provides an intelligent cooling system for full-power power take-off units in commercial vehicles, which solves the problem of engine temperature alarms caused by the large amount of heat generated by the full-power power take-off unit during long-term operation.

[0004] This utility model is achieved through the following technical solution:

[0005] An intelligent cooling system for a full-power power take-off unit in commercial vehicles includes a temperature detection module, a control module, an air-cooled cooling module, a liquid-cooled cooling module, and a fault monitoring module.

[0006] The temperature detection module is used to detect the operating temperature of the full-power power take-off unit in real time and transmit the temperature data to the control module. The temperature detection module uses a high-precision thermistor sensor, which is installed in the key heat-generating parts of the power take-off unit to ensure accurate acquisition of temperature information.

[0007] The control module receives temperature data from the temperature detection module and makes judgments and decisions based on preset temperature thresholds. When the power take-off (PTO) operating temperature is below the first threshold, the control module does not activate the air-cooled heat dissipation module to save energy. When the temperature is between the first and second thresholds, the control module adjusts the fan speed of the air-cooled heat dissipation module to increase proportionally with the temperature increase. When the temperature exceeds the second threshold, the control module simultaneously activates the liquid-cooled heat dissipation module and further increases the fan speed of the air-cooled heat dissipation module to achieve rapid heat dissipation. The control module uses a high-performance microprocessor with fast data processing and accurate control command output capabilities.

[0008] The air-cooled heat dissipation module includes a fan and a circulation pipe. The fan is installed near the power take-off, and the circulation pipe layout guides airflow across the surface of the circulation pipe to remove heat. The fan uses a variable frequency motor, which can operate at different speeds according to the instructions of the control module.

[0009] The liquid cooling heat dissipation module includes a coolant circulation pipeline, a coolant pump, a radiator, and a coolant storage tank. The coolant circulation pipeline is connected to the heat dissipation cavity of the full-power power take-off. The coolant pump delivers the coolant in the coolant storage tank to the heat dissipation cavity of the full-power power take-off through the circulation pipeline, carrying away the heat of the full-power power take-off body. The hot coolant is cooled by the radiator and then returns to the coolant storage tank for recycling.

[0010] The fault monitoring module is used to monitor the operating status of the air-cooled and liquid-cooled heat dissipation modules. For the air-cooled heat dissipation module, the fault monitoring module can monitor the fan speed and current parameters through wind speed and current sensors to determine whether the fan is working properly. For the liquid-cooled heat dissipation module, the fault monitoring module can monitor the flow rate and pressure of the coolant and the temperature of the radiator through flow rate, temperature and pressure sensors. Once abnormal parameters are detected, the fault monitoring module will send an alarm signal to the control module, and the control module can take corresponding emergency measures, including shutting down the power take-off to prevent overheating damage.

[0011] This invention can extend the continuous working time of the full-power power take-off, improve the service life of the full-power power take-off and the overall vehicle working efficiency, and features simple structure, intelligent start-up and no need for manual operation. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the components of this utility model. Detailed Implementation

[0013] like Figure 1 As shown, this utility model is an intelligent heat dissipation system for a full-power power take-off unit in a commercial vehicle, including a temperature detection module, a control module, an air-cooled heat dissipation module, a liquid-cooled heat dissipation module, and a fault monitoring module.

[0014] The temperature detection module is used to monitor the operating temperature of the full-power power take-off (PTO) in real time and transmit the temperature data to the control module. The temperature detection module uses a high-precision thermistor sensor, installed at key heat-generating components of the PTO, to ensure accurate temperature information acquisition.

[0015] The control module is the core of the entire heat dissipation system. It receives temperature data from the temperature detection module and makes judgments and decisions based on preset temperature thresholds. When the power take-off (PTO) operating temperature is below the first threshold, the control module does not activate the air-cooled heat dissipation module to save energy. When the temperature is between the first and second thresholds, the control module adjusts the fan speed of the air-cooled heat dissipation module, increasing it proportionally with the temperature rise. When the temperature exceeds the second threshold, the control module simultaneously activates the liquid-cooled heat dissipation module and further increases the fan speed of the air-cooled heat dissipation module to achieve rapid heat dissipation. The control module uses a high-performance microprocessor, possessing fast data processing and accurate control command output capabilities.

[0016] The air-cooled heat dissipation module includes a fan and circulation tubing. The fan is mounted near the power take-off (PTO), and the circulation tubing is strategically laid out to guide airflow across its surface, carrying away heat. The fan uses a variable-frequency motor, enabling it to operate at different speeds according to commands from the control module.

[0017] The liquid cooling module includes a coolant circulation pipeline, a coolant pump, a radiator, and a coolant storage tank. The coolant circulation pipeline is connected to the heat dissipation chamber of the full-power PTO. The coolant pump delivers coolant from the storage tank to the heat dissipation chamber of the full-power PTO through the circulation pipeline, carrying away the heat from the PTO body. The hot coolant is then cooled by the radiator and returned to the storage tank for reuse.

[0018] The fault monitoring module is used to monitor the operating status of both air-cooled and liquid-cooled heat dissipation modules. For air-cooled heat dissipation modules, it can monitor parameters such as fan speed and current through wind speed and current sensors to determine whether the fan is working properly. For liquid-cooled heat dissipation modules, it can monitor parameters such as coolant flow rate, pressure, and radiator temperature through sensors such as flow rate, temperature, and pressure. Once abnormal parameters are detected, the fault monitoring module will send an alarm signal to the control module, which can then take appropriate emergency measures, such as shutting down the power take-off to prevent overheating damage.

[0019] This invention can detect the actual operating temperature of the full-power power take-off (PTO) via a temperature detection module, flexibly adjust the heat dissipation method and intensity, and promptly monitor faults in the heat dissipation system. This effectively ensures the stable operation and service life of the full-power PTO and solves the problem of engine temperature alarms caused by the large amount of heat generated by the full-power PTO during long-term operation.
