[0019] The following describes the specific embodiments of the present utility model with reference to the drawings. In order to fully understand the present utility model, many details are described below, but for those skilled in the art, the present utility model can be implemented without these details.

[0020] As Figure 1 and Figure 2 shown, a miniature water cooling device mainly includes a condenser 1, a water inlet pipe 5 and a water outlet pipe 6. Among them, the condenser 1 includes a condenser body 11 and a heat dissipation mechanism 10, and the condenser body 11 is equipped with two heat dissipation mechanisms 10.

[0021] AsFigure 1 and Figure 2 As shown, preferably, the condenser body 11 is provided with a water passage chamber 112, a water inlet 111 and a water outlet 113 for each heat dissipation mechanism 10 to form two independent water cooling circuits.

[0022] Of course, the number of the heat dissipation mechanisms 10 is not limited to two, and may also be one, three, four, five,....

[0023] As Figure 1 and Figure 2 shown, the condenser body 11 is provided with a water passage chamber 112, and a water inlet 111 and a water outlet 113 communicating with the water passage chamber 112. After assembly, the water inlet pipe 5 communicates with the water inlet 111, and the water outlet pipe 6 communicates with the water outlet 113, thereby forming a water cooling circuit.

[0024] As Figure 1 and Figure 2 shown, the heat dissipation mechanism 10 includes two heat conducting fins 13, a heat conducting tube 14, a first connecting seat 15 and a second connecting seat 16. The heat conducting fin 13 includes an outer connecting section 131, an inclined transition section 132 and an inner connecting section 133 connected in sequence. The inner connecting sections 133 of the two heat conducting fins 13 are mutually attached up and down and extend into the interior of the water passage chamber 112, so that the inner connecting sections 133 are immersed in the cooling water inside the water passage chamber 112. The mutual attachment of the two inner connecting sections 133 facilitates reducing the volume of the device and is convenient for assembly.

[0025] The outer connecting sections 131 of the two heat conducting fins 13 are separated from each other up and down and are respectively fixedly connected to the upper and lower ends of the same first connecting seat 15. The separation of the two outer connecting sections 131 from each other up and down can increase the contact area between the heat conducting fin 13 and the air and improve the heat dissipation effect of conducting heat from the air to the heat conducting fin 13.

[0026] A heat conducting tube 14 is fixedly connected between the outer connecting sections 131 of the two heat conducting fins 13. Specifically, one end of the heat conducting tube 14 is fixedly connected to one of the heat conducting fins 13, and the other end is fixedly connected to the other heat conducting fin 13.

[0027] As Figure 1 and Figure 2 shown, preferably, the inner connecting sections 133 of the two heat conducting fins 13 attached to each other up and down are wrapped with a heat conducting layer 12 to increase the contact area with the cooling water and improve the heat dissipation effect of conducting heat from the heat conducting fin 13 to the cooling water. The shape of the water passage chamber 112 is adapted to the heat conducting layer 12, and there is a gap for the cooling water to flow between the inner wall of the water passage chamber 112 and the outer surface of the heat conducting layer 12.

[0028] As Figure 1 and Figure 2As shown, preferably, both the heat conduction tube 14 and the heat conduction fin 13 are made of copper or copper alloy. The heat conduction layer 12 is heat conductive silica gel, which has good heat conduction performance and flexibility to improve the overall heat conduction efficiency.

[0029] As Figure 1 and Figure 2 shown, preferably, the heat conduction tube 14 is U-shaped, and the middle part is a vertical section.

[0030] As Figure 1 and Figure 2 shown, the heat dissipation mechanism 10 further includes a second connection seat 16. Two connection arms 161 are oppositely arranged on the second connection seat 16, and a clamping groove 1611 is provided on the connection arm 161. The vertical section of the heat conduction tube 14 is clamped inside the clamping grooves 1611 of the two connection arms 161.

[0031] As Figure 1 and Figure 2 shown, it further includes a pressure relief valve 2, a temperature sensor 3 and a fixing frame 4. The pressure relief valve 2, the temperature sensor 3 and the condenser main body 11 are all fixedly installed on the fixing frame 4. And the water inlet pipe 5 is connected to the water inlet 111 through the pressure relief valve 2, and a temperature sensor 3 is also provided. The pressure relief valve 2 is used to automatically relieve pressure when an abnormal high pressure occurs. The probe of the temperature sensor 3 extends into the water cooling circuit to detect the temperature of the cooling water. Since the pressure relief valve 2 and the temperature sensor 3 are conventional components in the liquid circuit, their specific structures will not be described in detail here.

[0032] As Figure 1 and Figure 2 shown, preferably, the first connection seats 15 of the two heat dissipation mechanisms are fixedly connected, and the second connection seats 16 of the two heat dissipation mechanisms are fixedly connected.

[0033] As Figure 1 - Figure 3 shown, the present invention also discloses and protects a projector, which includes a projector housing a, and a light source a1, a lens a2 and a micro water cooling device a3 as described above are assembled inside the projector housing a. Among them, the first connection seat 15, the second connection seat 16 and the fixing frame 4 of the micro water cooling device a3 are all detachably and fixedly installed on the projector a by screws, and the heat dissipation mechanism 10 is beside the light source a1. Of course, a water tank (not shown in the figure) for storing cooling water and a water pump (not shown in the figure) should also be assembled inside the projector housing a to form a closed loop for flowing cooling water. The water tank and the water pump are conventional components in the existing water cooling technology and will not be described in detail here.

[0034] The above is only the specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection scope of the present invention.
