Abstract
The invention discloses a forced air cooling type heat radiation device for a temperature difference type engine, and particularly relates to a heat radiation device which uses heat generated when a high-power LED (Light-Emitting Diode) projection lamp works to drive the temperature difference type engine to rotate, so as to drive blades of a fan to rotate and realize the forced air cooling of heat radiation fins on a heat radiator heating pipe. With the adoption of the forced air cooling type heat radiation device for the temperature difference type engine, the heat generated when the high-power LED (Light-Emitting Diode) projection lamp works is used for heating gas in an engine air cylinder, so that a piston inside a piston cavity can move up and down through expansion and contraction of gas. The vertical motion of the piston is converted into circumference rotation of a shaft II through a push connecting rod; the circumference rotation of the shaft II drives the fan blades fixed on a shaft V to rotate; and the fan dissipates heat of the heat radiation fins on the heat radiator heating pipe in a forced convection manner, so that the temperature of the heat radiation fins is reduced. Therefore, the effect of forced heat transmission is realized.

Operation principle is as follows:
The part that the great power LED projecting lamp need to dispel the heat is connected with regional A on the base plate of radiator (1), and the heat that the great power LED projecting lamp produces is passed to engine base plate (5) through base plate of radiator (1).Engine base plate (5) is to the air heat in the cylinder (9), air expanded by heating pushing piston (11) in the cylinder (9) moves upward, piston (11) promotes connecting rod (13) and moves upward, and connecting rod (13) impeller-hub two (18) rotates around the axis of axle one (16).The rotation band moving axis three (19) of axle two (18) and axle four (21) rotate together around the axis of axle one (16).Because the determined plane of axis of axle two (18), axle three (19) is vertical with the determined plane of axis of axle four (21), axle three (19),, the rotation of axle four (21) moves downward push rod (8) and move gas device (7) and move downward thereupon so promoting connecting rod (24).When axle two (18) turned near peak, because the inertia of fan (22) flabellum, band moving axis five (23) was rotated further, because the rotation of axle five (23), axle two (18) will turn over peak.Because the space of moving below the gas device (7) is little, top space is large.Cylinder top board (27) and environmental exposure, the temperature of cylinder top board (27) is much smaller than the temperature of engine base plate (5).Gas temperature in the cylinder reduces, and gas pressure reduces.Piston (11) will move down, and piston (11) drivening rod (13) moves downward, and connecting rod (13) band moving axis two (18) moves downward.The rotation band moving axis three (19) of axle two (18) and axle four (21) rotate together around the axis of axle one (16).Because the determined plane of axis of axle two (18), axle three (19) is vertical with the determined plane of axis of axle four (21), axle three (19),, the rotation of axle four (21) moves upward push rod (8) and move gas device (7) and move upward thereupon so promoting connecting rod (24).When axle two (18) turned near minimum point, because the inertia of fan (22) flabellum, band moving axis five (23) was rotated further, because the rotation of axle five (23), axle two (18) will turn over minimum point.Because the space of moving below the gas device (7) is large, top space is little.When gases are heated, they expand in the cylinder, and gas pressure increases.Pushing piston (11) moves upward, and piston (11) promotes connecting rod (13) and moves upward, and connecting rod (13) impeller-hub two (18) rotates around the axis of axle one (16).Then repeat above process.
The continuous rotation of axle five (23) drives the continuous rotation of fan (22) flabellum fixed thereon.Heat pipe (2) evaporation section absorbs the heat on the base plate of radiator, and heat passed to working medium, form steam after the working medium heat absorption, this moment, heat was passed to steam in the latent heat mode, steam flows to condensation segment by steam channel under the effect of pressure reduction, and condensation on the gas-liquid interface of condensation segment, emit latent heat.Liberated heat by the liquid-sucking core of working medium and the heat conduction of tube wall, is passed to the outer fin (30) of heat pipe (2) from gas-liquid interface.The liquid of condensation relies on the capillary force effect to be back to evaporation section by liquid-sucking core, finishes a circulation.Fan (22) reduces the temperature of fin (30) to fin (30) forced convertion heat radiation, thereby plays the effect of augmentation of heat transfer.
