[0042] In the above-mentioned hard disk module, the heat sink 200 is connected to the hard disk body 100 and has a first side 210 and a second side 220 relative to each other. The first side 210 of the heat sink 200 is set toward the hard disk body 100 to achieve sufficient heat dissipation of the hard disk body 100. The first avoidance opening 230 of the heat sink 200 passes through the first side 210 and the second side 220. The back plate 300 is located on the second side 220 of the heat sink 200 and is provided with a second electrical connection portion 310. The second electrical connection portion 310 is electrically connected to the first electrical connection portion 110 through the first avoidance opening 230, thereby achieving electrical connection between the back plate 300 and the hard disk body 100, and then realizing functions such as power supply and data transmission for the hard disk body 100 through the second electrical connection portion 310 of the back plate 300; compared with conventional technology, the above-mentioned hard disk module can ensure the electrical connection between the back plate 300 and the hard disk body 100 while also being able to fully dissipate the heat of the hard disk body 100 through the heat sink 200, thereby ensuring the heat dissipation effect.

[0043] Optionally, the heat sink 200 may be a fan device for driving nearby airflow to remove heat from the hard disk body 100, or may be a liquid cooling device with flowing cooling liquid inside, which is not specifically limited here.

[0044] See also Figures 4 to 6 In one embodiment, the backplane 300 has a third side and a fourth side relative to each other, the third side is provided with a second electrical connection portion 310, and the fourth side is provided with a signal terminal 320 and a power terminal 330, the signal terminal 320 is used to connect the signal line, and the power terminal 330 is used to connect the power line, and the signal terminal 320 and the power terminal 330 are both electrically connected to the second electrical connection portion 310. In this way, when the second electrical connection portion 310 is electrically connected to the first electrical connection portion 110 of the hard disk body 100, data transmission and power supply can be performed on the hard disk body 100 through the signal terminal 320 and the power terminal 330 respectively.

[0045] Optionally, the second electrical connection part 310 can be passed through the first avoidance opening 230 and electrically connected to the first electrical connection part 110, and the first electrical connection part 110 can also be passed through the first avoidance opening 230 and electrically connected to the second electrical connection part 310. In addition, the second electrical connection part 310 and the first electrical connection part 110 can also be passed through the first avoidance opening 230 at the same time to achieve electrical connection between the two, which is not specifically limited here.

[0046] For further information, see Figure 3 and Figure 6 The first electrical connection part 110 includes a gold finger, and the second electrical connection part 310 includes a connector protruding from the third side of the back plate 300. The connector can pass through the first avoidance opening 230 and be electrically connected to the gold finger to achieve electrical connection between the back plate 300 and the hard disk body 100.

[0047] As a further explanation, in the conventional technology, the hard disk body 100 is provided with a first connecting portion on one side (hereinafter referred to as the electrical connection side) which is in close contact with the back plate 300, resulting in poor heat dissipation on the electrical connection side of the hard disk body 100, and the first electrical connection portion 110, as a component for data transmission, usually generates a high amount of heat, resulting in a high amount of heat on the electrical connection side, which further results in a high temperature on the electrical connection side; in the present application, the heat sink 200 is disposed between the hard disk body 100 and the back plate 300, and the electrical connection between the back plate 300 and the hard disk body 100 is achieved by opening a first avoidance opening 230, which not only enables the heat sink 200 to directly take away the heat on the electrical connection side of the hard disk body 100, but also facilitates the electrical connection between the back plate 300 and the hard disk body 100.

[0049] With such arrangement, the cooling liquid can enter the liquid cooling chamber through the liquid inlet portion 221, and the cooling liquid in the liquid cooling chamber can exchange heat with the hard disk body 100 to achieve heat dissipation of the hard disk body 100. The cooling liquid after heat exchange with the hard disk body 100 then flows out through the liquid outlet portion 222, so that the cooling liquid in the liquid cooling chamber remains in a flowing state, further ensuring the heat dissipation effect of the hard disk body 100. The second avoidance port 370 and the third avoidance port 380 on the back plate 300 respectively avoid the liquid inlet portion 221 and the liquid outlet portion 222, so that the liquid inlet portion 221 and the liquid outlet portion 222 are connected to the device for providing cooling liquid.

[0050] Furthermore, the device for providing cooling liquid can transport cooling liquid to the liquid inlet 221, and recover and cool the cooling liquid output by the liquid outlet 222 again, so that the cooling liquid in the cooling cavity always has a low temperature to ensure the heat dissipation effect of the hard disk body 100.

[0051] See also Figure 7 In one embodiment, a circumferentially continuous flow channel is provided between the liquid inlet portion 221 and the liquid outlet portion 222 for the coolant to flow.

[0052] Furthermore, the liquid inlet 221 and the liquid outlet 222 are both tubular structures, preferably cylindrical bodies, and the liquid inlet 221 and the liquid outlet 222 of the cylindrical body respectively pass through the second avoidance port 370 and the third avoidance port 380 for connecting with the equipment providing the coolant, and the connection effect is reliable.

At least two heat sinks 200 are provided and are arranged one-to-one with the hard disk groups.

Since the aperture of the first hole section 361 is smaller than the aperture of the second hole section 362, when the limiting rod 600 is passed through the first hole section 361, the limiting portion 610 can abut against the side of the back plate 300 away from the heat sink 200 to prevent the limiting portion 610 from detaching from the first hole section 361. At this time, the axis of the second screw hole 441 is colinear with the axis of the second through hole 341, so that the second threaded component can pass through the second through hole 341 and the second screw hole 441. Such a configuration can simplify the installation process of the back plate 300 and improve the installation efficiency.

[0076] For explanation, the first direction in the above embodiment may be the length direction of the back plate 300 or the width direction of the back plate 300, which may be flexibly adjusted according to actual conditions and is not specifically limited here. Figure 4In the embodiment shown, the first direction is the width direction of the back plate 300 (ie Figure 4 Similarly, the second direction in the above embodiment can be the length direction of the mounting member 400, or the width direction of the mounting member 400, which is not specifically limited here.

[0077] Furthermore, the limiting portion 610 is circular in shape, and the diameter of the circular limiting portion 610 is larger than the aperture of the first hole segment 361 and smaller than the aperture of the second hole segment 362 .

[0078] Another embodiment of the present application provides a server, which includes a chassis and a hard disk module as in any of the above embodiments, wherein the hard disk module is disposed in the chassis.

[0079] In the above-mentioned server, the heat sink 200 is connected to the hard disk body 100 and has a first side 210 and a second side 220 relative to each other. The first side 210 of the heat sink 200 is arranged toward the hard disk body 100 to achieve sufficient heat dissipation of the hard disk body 100. The first avoidance opening 230 of the heat sink 200 passes through the first side 210 and the second side 220. The back plate 300 is located on the second side 220 of the heat sink 200 and is provided with a second electrical connection portion 310. The second electrical connection portion 310 is electrically connected to the first electrical connection portion 110 through the first avoidance opening 230, thereby achieving electrical connection between the back plate 300 and the hard disk body 100, and then realizing functions such as power supply and data transmission for the hard disk body 100 through the second electrical connection portion 310 of the back plate 300. Compared with the conventional technology, the above-mentioned hard disk module can ensure the electrical connection between the back plate 300 and the hard disk body 100 while also being able to fully dissipate the heat of the hard disk body 100 through the heat sink 200, thereby ensuring the heat dissipation effect.

[0080] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
