DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , 3 .

[0021] The utility model liquid-cooled optical module comprises an optical engine component 1 and an upper cover 2 and a base 3 arranged on both sides of the optical engine component 1. The upper cover 2 and the base 3 form a first closed cavity A with the optical engine component 1, and a refrigerant is arranged in the first closed cavity A. A refrigeration device 4 is also arranged on the base 3, and the refrigerant in the first closed cavity A can enter the refrigeration device 4 and be output after being cooled. In this design, the refrigerant in the first closed cavity A contacts the optical engine component 1, absorbs the heat generated by the optical engine component 1 when in use, and the refrigerant after absorbing the heat flows into the refrigeration device 4, is cooled by the refrigeration device 4, and then flows into the first closed cavity A again after being cooled, so that the circulation is repeated to realize rapid heat exchange, so as to achieve a better heat dissipation effect; and in this embodiment, the refrigeration device 4 is embedded in the base 3 to reduce the size of the optical module, and the refrigerant is insulated and non-conductive.

[0022] In this embodiment, see Figure 3 The refrigeration device 4 includes a shell 401 with a second closed cavity B, a conduit 402 for introducing and exporting the refrigerant in the first closed cavity A into the second closed cavity B, and a refrigerator 403 for cooling the refrigerant in the second closed cavity B. With this design, the refrigerant flows from the high-pressure end to the low-pressure end under the principle of thermal expansion and contraction through the conduit 402, that is, from the first closed cavity A into the second closed cavity B, which facilitates the refrigerator 403 to cool the refrigerant, and from the first closed cavity A into the second closed cavity B, which facilitates the cooling of the light engine component 1 by the refrigerant after cooling. In this embodiment, the refrigerator 403 adopts the superconducting TEC in the prior art, and the conduit 402 is arranged on the base 3 and extends into the first closed cavity A.

[0023] In this embodiment, see Figure 1 The conduit 402 is a capillary conduit. This design allows the conduit 402 to be filled with many fine guide groove group structures, and the cold medium flows rapidly under the action of the capillary pressure gradient formed by the guide groove group structure itself.

[0024] In this embodiment, see Figure 1 , 3 The refrigeration device 4 further includes a heat conducting sheet 404 disposed at the housing 401 corresponding to the second sealed cavity B and a heat dissipating fin 405 connected to the heat conducting sheet 404, and the heat dissipating fin 405 is exposed to the outside. With this design, the heat dissipating fin 405 can release heat to the outside environment, and can be used together with the refrigerator 403 to enhance the heat dissipation effect. In this embodiment, the heat dissipating fin 405 is made of aluminum, the heat conducting sheet 404 is made of copper, the heat conducting sheet 404 and the heat dissipating fin 405 are located at the bottom of the base 3, and the heat dissipating fin 405 is exposed to the outside.

[0025] In this embodiment, see Figure 2 , 4 The heat conducting sheet 404 is provided with a plurality of protrusions 4041, and the housing 401 is provided with a plurality of grooves 4011 corresponding to and plugged into the plurality of protrusions 4041. This design increases the contact area between the heat conducting sheet 404 and the housing 401 and improves the heat conduction efficiency.

[0026] In this embodiment, see Figure 1 , 3 , and also includes a temperature sensing control unit 5 that can detect the external temperature and adjust whether the refrigeration device 4 works or not. With this design, the temperature sensing control unit 5 senses the ambient temperature and wind speed of the application scene. When the ambient temperature is too high in summer, the refrigeration device 4 is actively triggered to adjust the temperature. At night or in winter when the ambient temperature is low, when the natural heat dissipation capacity of the optical module itself can meet the heat dissipation, the refrigeration device 4 does not work. This is beneficial to energy saving, reducing losses and extending service life. In the present utility model, the temperature sensing control unit 5 directly controls the refrigerator 403, and the temperature sensing control unit 5 can be directly obtained from the prior art, so no further details are given here.

[0027] In this embodiment, see Figure 3 , the refrigerant medium wraps the light engine component 1. This design allows the refrigerant medium to contact the light engine component 1 in all directions and absorb heat quickly.

[0028] In this embodiment, see Figure 1 A sealing member 6 is further provided between the upper cover 2 and the base 3, and between the light engine assembly 1 and the base 3. This design can ensure that the coolant in the first closed cavity A is fully filled and does not leak out. In this embodiment, the sealing member 6 is designed in two types, one is ring-shaped, one side is located between the light engine assembly 1 and the upper cover 2, and the other three sides are located between the base 3 and the upper cover 2, and the other is strip-shaped, located between the light engine assembly 1 and the base 3.
