Description

Technical Field

[0001] The utility model relates to an application technology of a vehicle-mounted cooling fan, in particular to an adjustable vehicle-mounted cooling fan. Background Art

[0002] At present, most vehicles are equipped with cooling and heat dissipation devices such as air conditioners, but the air conditioning and refrigeration equipment needs to be installed inside a closed compartment. However, for special-purpose vehicles such as forklifts, due to usage requirements and the range of observation field of view, such vehicles cannot form a closed driving compartment. Existing conventional forklifts are not designed to be equipped with cooling fans for the driver to use when leaving the factory. This results in the driver not only having to endure the high temperature of the external environment in actual use, but also inhaling the exhaust gas emitted by the forklift engine itself, which is not good for the driver's actual driving experience and physical and mental health.

[0031] The controller 2 is equipped with a run button 201, an operating indicator light 202, and a fan speed adjustment button 203. A conversion interface 204, which can be a USB port, is provided at the bottom of the controller 2 for obtaining driving power from the vehicle. The run button 201 controls the start and stop of the main body 1. Using an external controller for device control facilitates quick power supply to the cooling fan, eliminating the need for additional wiring operations and saving operation time. Furthermore, the provision of different types of conversion interfaces significantly improves the cooling fan's adaptability to different vehicle interfaces.

[0032] like Figure 3-5 As shown, an air inlet baffle 103 and an air outlet baffle 105 are provided in the middle of the main body 1.
