Referring to fig. 1 and 2, a cooling system of a medical light source 10 includes a housing 1, a cooling plate 2, a first bracket 3, a second bracket 4, an elastic supporting member 5,L-shaped heat pipe 6, a heat sink 7, a fan 8, a temperature sensor 9, and a microprocessor (not shown); refrigeration piece 2, first support 3, second support 4, elastic support part 5,L shape heat pipe 6, radiator 7, fan 8, temperature sensor 9 and microprocessor all are located casing 1, temperature sensor 9, refrigeration piece 2 and fan 8 all are connected with the microprocessor electricity, the one end fixed connection of first support 3 is in bottom plate 15 of casing 1, the other end extends to roof 13, it has first recess to open on first support 3, elastic support part 5's one end fixed connection is in lateral plate 14 of casing 1, other end fixed connection is in first support 3, the one end fixed connection of second support 4 is in bottom plate 15 of casing 1, the other end extends to roof 13, it has second recess 11 to open on second support 4, refrigeration piece 2 installs between first support 3 and second support 4, and refrigeration piece 2's both ends are located first recess (not shown) and second recess 11 respectively, first support 3, refrigeration piece 2, second support 4 and bottom plate 15 enclose and close and form a cavity, this cavity is used for holding light source 10, the other end of refrigeration piece 2 is located the cavity of refrigeration piece 2, the heat pipe 7 is connected with radiator 7 towards the heat pipe 7 of L shape heat pipe 6, radiator and radiator 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 because 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 sink 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, so that the light and heat are emitted outwards.
When the temperature of the light source 10 is high, the heat dissipation requirement cannot be met only by the radiator 7 and the fan 8, and at the moment, the microprocessor sends a signal to the refrigerating sheet 2, so that 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 absorbed quickly; the heat dissipation surface of the refrigeration piece 2 is connected with one end of the L-shaped heat pipe 6, heat-conducting silicone grease is arranged between the L-shaped heat pipe 6 and the heat dissipation surface of the refrigeration piece 2, heat-conducting 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, and is finally discharged out of the shell 1 through the fan 8 by the heat-conducting silicone grease between the heat dissipation surface of the refrigeration piece 2 and the L-shaped heat pipe 6, the heat-conducting silicone grease between the L-shaped heat pipe 6,L and the radiator 7, and the medical light source 10 can continue to operate normally.
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 fig. 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 diagnostic 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 plate 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 installed 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.
