Separable liquid-cooled Led (Light Emitting Diode) radiator

Abstract

The invention discloses a separable liquid-cooled Led (Light Emitting Diode) radiator. The separable liquid-cooled Led (Light Emitting Diode) radiator comprises a radiator base and heat radiating blocks, wherein a power plug and a clamping groove are arranged on the radiator base, each heat radiating block consists of a cooling liquid tank, large gears, blades, clamping pieces and a motor frame, the cooling liquid tank is sealed by using an insertion piece, the insertion piece is fixedly arranged between the large gears at the two ends, blade rods are arranged outside the cooling liquid tank, the blades sleeve the blade rods, the top end and the bottom end of the blade rods are respectively provided with a small gear, the small gears are engaged and connected with the large gears, the clamping pieces are arranged outside the small gears, sleeve the blade rods and are fixed by using nuts, the motor frame is arranged in the cooling liquid tank and is fixed on the clamping piece by using screws, and the clamping pieces are fit and connected with the clamping grooves. The radiator utilizes the feature of high specific heat capacity of liquid, a great amount of heat is taken away with the rotation of the cooling liquid tank, the blades rotate and drive surrounding air to flow and the heat radiating effect is increased. Since the distribution and the number of the heat radiating blocks can be adjusted according to actual situations, more reasonable LED heat radiation is realized.

Description

technical field [0001] The invention relates to a radiator, in particular to a separable liquid-cooled LED radiator. Background technique [0002] LED, that is, a light-emitting diode, has a very low working voltage; a small working current; good shock and shock resistance, high reliability, and long life; the strength of the light can be easily modulated by modulating the strength of the passing current. . Due to these advantages, LEDs are used as light sources in many photoelectric control devices. However, due to the heat concentrated in the chip with a small size, the temperature of the chip rises, causing non-uniform distribution of thermal stress, chip luminous efficiency and phosphor laser efficiency decrease; when the temperature exceeds a certain value, the failure rate of the device is exponential Increase, the heat dissipation of LED directly affects its quality and life. Therefore, the LED heat sink can increase the service life and stability of the LED. The ...

Problems solved by technology

The LED heat sink with the application number 201320638681.5 uses a fixed number of cooling blocks, which cannot be properly adjusted according to the actual temperature of the LED. Moreover, this LED heat sink only uses one exhaust fan, and the heat dissipation effect is too concentrated and the heat is too high. Concentrated, not very good for heat dissipation
