Referring to fig. 1 and 2, a cooling system for a medical light source 10 includes a housing 1, a cooling fin 2, a first bracket 3, a second bracket 4, an elastic support 5, an L-shaped heat pipe 6, a heat sink 7, a fan 8, a temperature sensor 9, and a microprocessor (not shown); the refrigeration piece 2, the first support 3, the second support 4, the elastic support piece 5, the L-shaped heat pipe 6, the radiator 7, the fan 8, the temperature sensor 9 and the microprocessor are all positioned in the shell 1, the temperature sensor 9, the refrigeration piece 2 and the fan 8 are all electrically connected with the microprocessor, one end of the first support 3 is fixedly connected with a bottom plate 15 of the shell 1, the other end of the first support 3 extends towards a top plate 13, a first groove is formed in the first support 3, one end of the elastic support piece 5 is fixedly connected with a side plate 14 of the shell 1, the other end of the elastic support piece is fixedly connected with the first support 3, one end of the second support 4 is fixedly connected with the bottom plate 15 of the shell 1, the other end of the second support 4 extends towards the top plate 13, a second groove 11 is formed in the second support 4, the refrigeration piece 2 is installed between the first support 3 and the second support 4, and two ends of the refrigeration, first support 3, refrigeration piece 2, second support 4 and bottom plate 15 enclose to close and form a hollow cavity, and this cavity is used for holding light source 10, and the refrigeration face of refrigeration piece 2 is connected with the cooling surface of refrigeration piece 2 towards the cavity, the one end of L shape heat pipe 6, the other end and radiator 7 are connected, radiator 7 and fan 8 fixed connection.

The temperature sensor 9 is fixedly arranged on the surface of the second bracket 4 facing the chamber, is relatively close to the light source 10, and can efficiently detect the temperature of the light source 10; and since the temperature sensor 9 is electrically connected with the microprocessor, the microprocessor can monitor the temperature of the light source 10 in real time through the temperature sensor 9. When the light source 10 just starts to work, the temperature is not high, and the heat dissipation operation of the fan 8 and the heat dissipation fins is not needed; when the temperature of the light source 10 reaches a certain value, the microprocessor sends a signal to the fan 8, and the fan 8 starts to operate after receiving the signal to emit the light and heat outwards.

When the temperature of the light source 10 is higher, the heat dissipation requirement cannot be met only by the radiator 7 and the fan 8, at the moment, the microprocessor sends a signal to the refrigerating sheet 2, and the refrigerating sheet 2 starts to work; the refrigerating surface of the refrigerating sheet 2 faces the chamber and is very close to the light source 10, so that heat emitted by the light source 10 can be quickly absorbed; the heat dissipation surface of the refrigeration piece 2 is connected with one end of the L-shaped heat pipe 6, heat conduction silicone grease is arranged between the heat dissipation surfaces of the L-shaped heat pipe 6 and the refrigeration piece 2, heat conduction silicone grease is also arranged between the L-shaped heat pipe 6 and the radiator 7, the L-shaped heat pipe 6 is preferably made of copper and has good heat dissipation performance, therefore, a large amount of heat emitted by the light source 10 sequentially passes through the refrigeration surface of the refrigeration piece 2, the heat conduction silicone grease is arranged between the heat dissipation surface of the refrigeration piece 2 and the L-shaped heat pipe 6, the heat conduction silicone grease arranged between the L-shaped heat pipe 6 and the radiator 7, the radiator 7 is finally discharged out of the shell 1 by the fan 8, the temperature inside the shell 1 is reduced, and the medical light source.

In order for the refrigerating plate 2 to be able to operate normally, the refrigerating plate 2 must be installed at a suitable position. As shown in fig. 1 and 2, the light source 10 is located inside the housing 1, and the second support 4 is provided with a through hole 16, and light emitted by the light source 10 enters the lens 12 through the through hole 16 and irradiates a diseased part or a diagnosis part of a patient; the second support 4 is preferably made of a rigid material, the microprocessor is preferably mounted on the side of the second support 4 remote from the chamber, and the temperature sensor 9 can be in signal connection with the microprocessor via bluetooth.

Since the refrigerating fins 2 are located between the first bracket 3 and the second bracket 4, and both ends of the refrigerating fins 2 are respectively installed in the first groove (not shown) and the second groove 11, in order to better adjust the position of the refrigerating fins 2, the first bracket 3 is an elastic bracket made of elastic plastic; the elastic support 5 is a spring.

When the refrigerating sheet 2 breaks down, the refrigerating sheet 2 needs to be replaced; pushing the first bracket 3 away from the second bracket 4 so that one end of the refrigeration sheet 2 leaves the first groove and is taken out of the second groove 11; one end of a new refrigerating sheet 2 is inserted into the second groove 11, the other end of the new refrigerating sheet is placed into the first groove, the spring pushes the first support 3 to reset at the moment, and the refrigerating sheet 2 can be stably arranged between the first support 3 and the second support 4; and because the first bracket 3 is made of elastic material and the buffering function of the spring is added, even if the medical light source 10 is vibrated, the normal work is not influenced.

The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
