Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The following describes the heat sink assembly 20 according to an embodiment of the present invention with reference to fig. 1 to 5, and the present invention also proposes a power assembly 100 having the heat sink assembly 20 described above, and further, the present invention also proposes a server S having the power assembly 100 described above. The heat sink assembly 20 can dissipate heat of the force calculating assembly 100, thereby improving the heat dissipation efficiency of the force calculating assembly 100 and preventing the excessive temperature of the force calculating assembly 100 from damaging electronic components such as chips.
As shown in fig. 3 to 5, the heat sink assembly 20 includes: a first heat sink 21 and a second heat sink 22, the first heat sink 21 including: a first heat dissipation substrate 211, a side surface of the first heat dissipation substrate 211 is provided with a main heat pipe 212, and the second heat sink 22 includes: the second heat dissipation substrate 221, a heat pipe extension 222 is disposed on one side surface of the second heat dissipation substrate 221, and the first heat sink 21 and the second heat sink 22 are disposed at an interval. The heat pipe is mainly used for transferring heat by the vapor-liquid phase change of the working liquid, so that the heat resistance of the heat pipe is low, and the heat pipe has high heat conduction capability. By providing the heat pipes on both the first heat sink 21 and the second heat sink 22, the heat pipes have good thermal conductivity, so that the heat dissipation capability of the heat sink assembly 20 can be further improved.
Also, as shown in fig. 3 to 5, the main heat pipe 212 and the heat pipe extension 222 are disposed on the same side, and the size of the second radiator 22 in the first direction is smaller than the size of the first radiator 21 in the first direction. That is, the height of the first heat sink 21 is smaller than the height of the second heat sink 22. In addition, the side of the first heat sink 21 away from the first heat dissipation substrate 211 and the side of the second heat sink 22 away from the second heat dissipation substrate 221 are on the same plane. Since the height of the first heat sink 21 is smaller than that of the second heat sink 22, and the end of the first heat sink 21 away from the first heat dissipation substrate 211 and the end of the second heat sink 22 away from the second heat dissipation substrate 221 are on the same plane, that is, the first heat dissipation substrate 211 and the second heat dissipation substrate 221 are not on the same plane, the accommodation space 24 can be left on the heat sink assembly 20.
In this way, by dividing the heat sink assembly 20 into the first heat sink 21 and the second heat sink 22, the effective heat dissipation area of the heat sink assembly 20 can be increased when the heat sink assembly 20 is connected to the force calculating assembly 100, and the heat dissipation efficiency of the heat sink assembly 20 can be increased. Because the electrical components on the force computing assembly 100 usually protrude from the surface of the force computing board 10, the accommodating space 24 is provided between the first heat sink 21 and the second heat sink 22, so that the space above the electrical components can be utilized, the heat sink assembly 20 can fully utilize the space inside the server S to extend the heat dissipation area of the heat sink assembly 20, and the heat dissipation capacity of the heat sink assembly 20 can be further improved.
Wherein the first direction is a height direction of the first heat sink 21.
Thus, by dividing the heat sink assembly 20 into the first heat sink 21 and the second heat sink 22, the space inside the force calculating assembly 100 can be fully utilized, so that the heat dissipation area of the heat sink assembly 20 can be increased, and the heat dissipation capability of the heat sink assembly 20 can be increased.
According to the first embodiment of the present invention, as shown in fig. 3, the accommodating space 24 is provided with the connecting heat pipe 23 at a side adjacent to the first heat sink 21, and the connecting heat pipe 23 is connected between the main heat pipe 212 and the heat pipe extension 222. By arranging the connecting heat pipe 23, the main heat pipe 212 and the heat pipe extension 222 can be connected, so that heat exchange can be generated between the main heat pipe 212 and the heat pipe extension 222, and further, heat is introduced into the second heat sink 22, and the overall heat dissipation capacity is improved.
Specifically, the main heat pipe 212, the heat pipe extension 222, and the connecting heat pipe 23 are typically made by bending the same heat pipe.
As shown in fig. 3, the first heat sink 21 further includes: a first heat sink 213, one side surface of the first heat dissipation substrate 211 is provided with the main heat pipe 212, and the other side surface of the first heat dissipation substrate 211 is provided with the first heat sink 213. The second heat sink 22 further includes: a second heat sink 223, one side surface of the second heat dissipation substrate 221 is provided with a heat pipe extension 222, and the other side surface of the second heat dissipation substrate 221 is provided with the second heat sink 223. By arranging the first heat sink 213 on the first heat sink substrate 211 and the second heat sink 223 on the second heat sink substrate 221, the contact area between the heat sink assembly 20 and the air can be increased, so that heat can be conveniently transferred to the air, and the heat dissipation efficiency of the heat sink assembly 20 can be improved.
For example, the first heat sink 21 is provided with the first heat sink fins 213 connected to the first heat sink substrate 211, so that when the electric components corresponding to the first heat sink 21 generate heat, the heat is transferred to the first heat sink substrate 211, the first heat sink fins 213 are formed in a plurality of parallel plate structures, and the contact area between the first heat sink fins 213 and the air is large, so that the heat can be transferred to the air through the first heat sink fins 213. In addition, by providing the main heat pipe 212 on the first heat dissipation substrate 211, the heat conduction efficiency between the first heat dissipation substrate 211 and the electrical component can be improved.
In addition, a first groove is formed on a side surface of the first heat dissipation substrate 211 away from the first heat dissipation fin 213, the main heat pipe 212 is embedded in the first groove, a second groove is formed on a side surface of the second heat dissipation substrate 221 away from the second heat dissipation fin 223, and the heat pipe extension 222 is embedded in the second groove. Through setting up first recess on first heat dissipation base plate 211 to inlay main heat pipe 212 in locating first recess, thereby can make first heat dissipation base plate 211 and calculate power subassembly 100 when contacting, promote the heat exchange efficiency between first heat dissipation base plate 211 and the electrical components through main heat pipe 212. Similarly, the second heat dissipation substrate 221 is provided with a second groove, and the heat pipe extension 222 is embedded in the second groove, so that the heat exchange efficiency between the first heat dissipation substrate 211 and the electrical component is improved. In addition, the space of the heat sink assembly 20 can be effectively utilized, so that the volume and the heat dissipation area of the heat sink assembly 20 can be further increased.
As shown in fig. 3, a heat conductive pad 214 is disposed on a surface of the first heat dissipation substrate 211 away from the first heat sink 213, and the heat conductive pad 214 protrudes from the surface of the first heat dissipation substrate 211. The heat sink assembly 20 may be better contacted by the electrical components via the thermal pad 214, thereby better transferring heat between the heat sink assembly 20 and the electrical components. Furthermore, the heat sink assembly 20 and some components around the electrical components can be easily avoided.
Specifically, the thermal pad 214 is a thermal copper pad, which has good thermal conductivity, so that heat on the electrical component can be transferred to the heat sink assembly 20.
In addition, the heat conducting pad 214 and the heat pipe are directly welded to the heat sink assembly 20, so that the heat dissipation effect is better and the heat pipe cannot be detached during use.
As shown in fig. 3, the projection of the thermal pad 214 on the surface of the first heat dissipation substrate 211 and the projection of the primary heat pipe 212 on the surface of the first heat dissipation substrate 211 have an overlapping region. That is, one face of the thermal pad 214 is in contact with the electrical component and the other face is in contact with the primary heat pipe 212. So set up, can transmit the heat fine transmission for main heat pipe 212 of thermal pad 214 with the electronic component to can promote the radiating efficiency of radiator module 20.
According to the second embodiment of the present invention, as shown in fig. 4, the first heat sink 21 further includes: the heat spreader 215 is disposed on a surface of the first heat sink substrate 211 away from the first heat sink 213. The vapor chamber 215 has good thermal conductivity. By providing the soaking plate 215 on the first heat dissipating substrate 211, the heat generated from the force calculating assembly 100 can be well transmitted and diffused to the entire surface of the first heat dissipating substrate 211, and then transmitted to the outside through the first heat dissipating fin 213. Thus, the heat dissipation efficiency of the heat sink assembly 20 can be improved. Specifically, the heat conductive pad 214 is disposed on the soaking plate 215.
According to a third embodiment of the invention, as shown in fig. 5, the first heat-dissipating substrate 211 may be a heat-equalizing plate 215. That is, the soaking plate 215 replaces the first heat dissipating substrate 211. The soaking plate 215 can better diffuse heat to the entire plane of the first heat-dissipating substrate 211, and the heat transfer efficiency is higher. When the heat sink assembly 20 abuts against the force computing assembly 100, heat generated from the electrical component is directly transferred to the heat spreader plate 215, and then transferred to the outside through the first heat sink 213 attached to the heat spreader plate 215. With this arrangement, the heat dissipation efficiency of the heat sink assembly 20 can be improved. Specifically, the heat conducting pad 214 is disposed on the soaking plate 215, and the main heat pipe 212 is embedded on the soaking plate 215.
As shown in fig. 3, the length direction of the primary heat pipe 212 is the second direction, the third direction is the width direction of the first heat sink 21, and the heat pipe extension 222 includes: a first subsection 2221 and a second subsection 2222 are connected, the length direction of the first subsection 2221 is a second direction, the first subsection 2221 corresponds to the main heat pipe 212, and the length direction of the second subsection 2222 is a third direction. By dividing the heat pipe extension 222 into the first subsection 2221 and the second subsection 2222, which are connected, the area of the heat pipe extension 222 on the second heat sink 22 can be increased, that is, the heat dissipation area can be effectively increased, and not only is the remaining space inside the second heat sink 22 effectively utilized, but also the heat dissipation efficiency of the second heat sink 22 can be improved.
As shown in fig. 3 to 5, the main heat pipe 212 is divided into two sub heat pipes, the two sub heat pipes are two heat pipes spaced on the first heat dissipation substrate 211, the first subsection 2221 and the second subsection 2222 are both two, and one of the sub heat pipes is connected with one of the first subsections 2221 through the connecting heat pipe 23. By arranging the main heat pipe 212 as two sub heat pipes, the area of the main heat pipe 212 on the first heat sink 21 can be increased, that is, the heat dissipation area can be effectively increased, so that the heat dissipation efficiency of the first heat sink 21 can be improved. Moreover, one of the sub-heat pipes is connected to one of the first sub-sections 2221 through the connecting heat pipe 23, so that not only the laying area of the heat pipe on the heat sink assembly 20 can be increased, but also the first heat sink 21 and the second heat sink 22 can be connected together, and thus the heat dissipation efficiency of the heat sink assembly 20 can be increased.
According to the force computing assembly 100 of the second aspect of the embodiment of the present invention, as shown in fig. 2, the force computing assembly 100 includes: the force calculation board 10 comprises a force calculation substrate 11, a first electric component 12 and a second electric component 13, wherein the first electric component 12 and the second electric component 13 are both arranged on one side surface of the force calculation substrate 11, and the first electric component 12 and the second electric component 13 are arranged on the side surface at intervals; the first heat dissipation substrate 211 is disposed on the first side surface of the computation substrate 11, the first heat dissipation substrate 211 is disposed opposite to the first electrical component 12, the second heat dissipation substrate 221 is disposed on the first side surface of the computation substrate 11, the second heat dissipation substrate 221 is disposed opposite to the second electrical component 13, and the second electrical component 13 is disposed in the accommodating space 24.
That is to say, the first heat sink 21 and the first electrical component 12 are disposed correspondingly, and the second heat sink 22 and the second electrical component 13 are disposed correspondingly, because the height of the second electrical component 13 protruding out of the computation force board 10 is greater than the height of the first electrical component 12 protruding out of the computation force board 10, and thus, the accommodating space 24 is disposed on the heat sink assembly 20, and both the first heat sink 21 and the second heat sink 22 can be disposed close to the computation force board 10, so that the heat dissipation efficiency of the computation force assembly 100 can be improved.
Specifically, the first electrical component 12 is a chip, and the second electrical component 13 is a power supply MOS.

The multiple sets of force computing assemblies 100 are stacked in the box 200 to facilitate heat dissipation of the force computing assemblies 100. The fan 300 may blow heat generated from the force calculating assembly 100 out of the case 200.
