Abstract:
A device for dissipating heat from a car, said device having discharge ports the angle of which is adjustable and comprising:a body that is comprised of left and right casings which together define a hollow interior, upper and lower portions of which receive an air discharge rotary cylinder and a fan blade shaft respectively, said body being provided with a plurality of spaced elongate slots along a longitudinal direction thereof at where said fan blade shaft is, said body being further provided with a curved slide slot, one end of said body being externally connected to a power source wire, both sides of a bottom portion of said body being provided with opposite clamp seats;said air discharge rotary cylinder, one portion thereof being within the upper portion of the hollow interior of said body and having a suitably large opening such that said air discharge rotary cylinder can communicate with said fan blade shaft, the other portion being exposed on the outside of said body and being provided with a plurality of discharge ports, both ends of said air discharge rotary cylinder being clamped by said body such that it may rotate therein, said air discharge rotary cylinder further having a trigger rod projecting from its surface that passes through said slide slot of said body;said fan blade shaft, having a plurality of fan blades projecting radially from a shaft portion thereof along a longitudinal direction;a securing device that includes a wedge-shaped insert plate extending downwardly from the bottom portion of said body and an elastic clamp plate, said clamp plate having an inverted L-shape and including a horizontal portion and a vertical portion, both sides of said horizontal portion being held in said clamp seats of said body, said clamp plate having expansion springs provided at a front edge thereof for connecting said clamp plate to the bottom portion of said body so that said clamp plate can be held in an elastic state, whereby said body may be secured on a car door and is connected by said power source wire to a main body that is provided with a control circuit, said main body being connected to a car window drive circuit so that, before the driver goes into the car, he/she can lower the car window using a remote controller and actuate said body to start drawing out the hot air inside the car to thereby lower the temperature of the car, said trigger rod of said air discharge rotary cylinder being controllable to adjust the angle of said discharge ports.
