Abstract
The utility model relates to an LED heat radiator which is arranged on an LED and adopts a liquid heat radiator. Because a liquid heat radiator is adopted in the utility model and a fan is arranged on the liquid heat radiator, the heat radiation of the LED is easier and the heat radiation effect is more ideal. Compared with the prior art under the condition of equal heat radiation quantity, the volume of the heat radiator becomes smaller, the installation is easy, and the cost is low; simultaneously, a temperature controller is also arranged on the LED heat radiator, the starting and the stopping of the LED or a fan can be well protected, both the security and the reliability of the operation of the LED are enhanced, and the normal service life of the LED is guaranteed.
Description
Technical field
The utility model relates to a kind of radiator, especially relates to the radiator on a kind of LED of being applied in.
Background technology
LED can since when work the heat that produces and temperature rises, when temperature surpasses the highest bearing temperature value of LED, will burn out LED, especially Yin Wendu is too high and to burn out the problem of LED more outstanding on the great power LED.In order to solve the too high technical problem of bringing to the operate as normal of LED of temperature, generally adopt at present to LED radiator is installed, increase the area of dissipation of LED, thereby the heat that produces when making LED work in time is dispersed in the air and goes, but because this mode mainly is to dispel the heat by the mode of free convection, when higher the or power of LED is very big in temperature, too high for fear of the temperature of LED, just need enough big area of dissipation, and, the radiator of existing application on LED is metal heat sink, and its heat-conducting effect neither be very desirable, therefore, the volume ratio of radiator is bigger, it is bigger to take up room, and inconvenience is installed, and cost is also than higher.And; at present in LED uses; LED is last not to have other safeguard measure yet except the radiator of installing; when to such an extent as to the thermolysis of the very high radiator of environment temperature is very little relatively; self temperature of LED can very fast rising; thereby LED is burnt out, and therefore, it is too high and to burn out the problem of LED particularly necessary to solve Yin Wendu.
The utility model content
The Yin Wendu described in the background technology is too high in order to solve, the radiator heat-dissipation effect is undesirable and the technical problem that causes LED to be burnt out for the utility model, and provide a kind of LED radiator, this radiator volume is little, good heat dissipation effect, be easy to install, and can realize automatic control, be applicable in the environment of higher temperature.
Technical solution of the present utility model is: the utility model is a kind of LED radiator, and described radiator is arranged on the LED, and its special character is that described radiator is a liquid radiator.
Above-mentioned radiator is provided with temperature control equipment, and described temperature control equipment and LED are electrically connected.
Above-mentioned radiator is provided with fan.
Above-mentioned radiator is provided with temperature control equipment, and described temperature control equipment comprises first temperature control equipment and second temperature control equipment; Described first temperature control equipment and LED are electrically connected; Described second temperature control equipment and fan are electrically connected.
The temperature controlling range of above-mentioned first temperature control equipment is 0-75 ℃; The temperature controlling range of second temperature control equipment is 0-50 ℃.
The said temperature control device is the bimetal leaf temperature controller.
The utility model has been owing to adopted liquid radiator, and is provided with fan thereon, makes that the heat radiation of LED is easier, effect is better, under the situation that heat dissipation capacity is equal to, compare with prior art, and the smaller volume of radiator, it is easy, with low cost to install; Simultaneously, the utility model also is provided with temperature controller, can well protect the start and stop of LED or fan, has improved security, the reliability of LED work, has guaranteed the normal service life of LED.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the first temperature control equipment schematic diagram of the present utility model.
Fig. 3 is the second temperature control equipment schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises LED1, radiator 2, fan 3, first temperature control equipment 4 and second temperature control equipment 5, and wherein, radiator 2 is installed on the LED1; Fan 3 is installed on the radiator 2; The temperature sense pin A and the radiator 2 of first temperature control equipment 4 is connected, the positive pole of pin B and LED1 joins, the negative pole of pin C and LED1 joins, thus, when the temperature of LED1 surpasses the maximum control temperature of first temperature control equipment 4, first temperature control equipment 4 will move the power supply of cutting off LED1, thereby well protects LED1; The temperature controlling range of described first temperature control equipment 4 is 0-75 ℃.
The temperature sense pin D and the radiator 2 of second temperature control equipment 5 is connected, the positive pole of pin E and fan 3 joins, the negative pole of pin F and fan 3 joins, when the LED1 temperature is higher than the maximum control temperature of second temperature control equipment 5, second temperature control equipment 5 just can move, give fan 3 power supplies, make fan 3 entrys into service; When the LED1 temperature was lower than the maximum control temperature of second temperature control equipment 5, the power supply to fan 3 was cut off in 5 actions of second temperature control equipment, thereby played the purpose of economize on electricity.Described, the temperature controlling range of second temperature control equipment 5 is 0-50 ℃.
Temperature control equipment in the present embodiment can be the bimetal leaf temperature controller, and the structure of radiator 2, shape can design according to actual needs, mainly be the application installation environment design according to LED that convenient installation can be saved cost again simultaneously and be got final product.
