Description

Technical Field

[0001] This utility model relates to the field of unmanned helicopter technology, and in particular to an integrated heat dissipation system for unmanned helicopters. Background Technology

[0002] Currently, most unmanned helicopters use piston engines as their power source. The combustion of fuel generates a lot of heat, so a cooling system is needed to cool the engine. In order to increase power, most engines use superchargers to increase intake pressure, which also raises the intake temperature. A cooling system is needed to lower the intake temperature to ensure that the engine can work normally.

[0003] The cooling system of unmanned helicopters generally consists of a water-cooled radiator and an intercooler, which respectively cool the engine body and the engine intake. Currently, the water-cooled radiator and the intercooler of unmanned helicopters each have an independent fan and are arranged separately, which makes the unmanned helicopters large in size and weight, and poses certain difficulties in the overall layout of the unmanned helicopter. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide an integrated heat dissipation system for unmanned helicopters to solve the problem of the large size of existing unmanned helicopter heat dissipation systems.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] An integrated cooling system for unmanned helicopters is disclosed for cooling the unmanned helicopter engine. It includes a water-cooled radiator, an intercooler, a fan, and a transmission mechanism. The intercooler, water-cooled radiator, and fan are sequentially stacked and integrated. The water-cooled radiator cools the unmanned helicopter engine, and the intercooler cools the engine's intake air. The fan is connected to the crankshaft of the unmanned helicopter engine via the transmission mechanism. The rotation of the crankshaft drives the transmission mechanism to rotate the fan. The fan rotation causes high-speed airflow over the intercooler and water-cooled radiator, thereby cooling them through strong convection.

[0007] Furthermore, the transmission mechanism includes a speed reducer, a drive shaft, and a drive belt.

[0008] Furthermore, the reducer is connected to the crankshaft of the unmanned helicopter engine, one end of the drive shaft is connected to the output end of the reducer, and the other end is connected to the drive belt, which is connected to the fan.

[0009] Furthermore, it also includes a water-cooled heat dissipation pipeline, which includes an inlet pipe and an outlet pipe.

[0010] Furthermore, one end of the water inlet pipe is connected to the outlet of the unmanned helicopter engine, and the other end is connected to the inlet of the water-cooled radiator, for transporting the high-temperature cooling water of the unmanned helicopter engine to the water-cooled radiator for heat dissipation and cooling.

[0011] Furthermore, one end of the water outlet pipe is connected to the outlet of the water-cooled radiator, and the other end is connected to the inlet of the unmanned helicopter engine, for transporting the cooled low-temperature cooling water back to the unmanned helicopter engine.

[0012] Furthermore, it also includes an intercooling heat dissipation pipeline, which includes an intake pipeline and an exhaust pipeline.

[0013] Furthermore, one end of the intake pipe is connected to the turbocharger of the unmanned helicopter engine, and the other end is connected to the air inlet of the intercooler radiator, which is used to deliver the high-temperature air in the turbocharger to the intercooler radiator for heat dissipation and cooling.

[0014] Furthermore, one end of the exhaust pipe is connected to the exhaust port of the intercooler radiator, and the other end is connected to the intake manifold of the unmanned helicopter engine, for delivering the cooled air back to the engine.

[0015] Furthermore, it also includes a fan cover, which is disposed on the fan.

[0016] The technical solution of this utility model can achieve at least one of the following effects:

[0017] (1) This utility model provides an integrated heat dissipation system for unmanned helicopters, including a water-cooled radiator, an intercooler, a fan, and a transmission mechanism. The intercooler, water-cooled radiator, and fan are stacked and integrated in sequence. The water-cooled radiator is used to cool the unmanned helicopter engine, and the intercooler is used to cool the intake air of the unmanned helicopter engine. The fan is connected to the crankshaft of the unmanned helicopter engine through the transmission mechanism, so that the rotation of the crankshaft of the unmanned helicopter engine drives the transmission mechanism to drive the fan to rotate. The rotation of the fan causes air to flow at high speed through the intercooler and water-cooled radiator, thereby cooling the intercooler and water-cooled radiator through strong convection. This utility model reduces the size and weight of the unmanned helicopter heat dissipation system, and makes the structure compact, saving space and power. It also reduces the weight of the generator and battery in the unmanned helicopter, thereby greatly reducing the weight of the unmanned helicopter and reducing the difficulty of the overall layout of the unmanned helicopter.

[0018] (2) The transmission mechanism in this utility model includes a reducer, a transmission shaft and a transmission belt. The reducer is connected to the crankshaft of the unmanned helicopter engine. One end of the transmission shaft is connected to the output end of the reducer and the other end is connected to the transmission belt. The transmission belt is connected to the fan, thereby transmitting the rotation of the crankshaft of the unmanned helicopter engine to the fan. The rotation of the fan causes air to flow at high speed through the intercooler and the water-cooler, thereby cooling the intercooler and the water-cooler through strong convection. The fan rotation is directly powered by the unmanned helicopter engine, without the need for electricity, thus saving the power of the unmanned helicopter.

Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention.
