Please refer to FIG. 1 and FIG. 1 is an embodiment of the present invention. A schematic view of the server. The server 5 includes a cabinet 10, a servo host 20, and a fan module 30. The servo host 20 is disposed in the cabinet 10. The fan module 30 is disposed in the cabinet 10 . The servo host 20 is moved into the cabinet 10 or extracted from the cabinet 10 along a first direction D1. The airflow generated by the fan module 30 flows in the cabinet 10 along a second direction D2. In the present embodiment, the first direction D1 is perpendicular to the second direction D2. However, the first direction D1 is perpendicular to the second direction D2 and is not intended to limit the present invention. In other embodiments, the first direction D1 may be parallel to the second direction D2.

The structure of the servo host 20 will be described in more detail below. Please refer to "2A" and "2B", "2A" is a schematic view of the "1st" servo host, and "2B" is the "1st" servo host and fan module Schematic diagram of the section. The servo host 20 includes a casing 210, a circuit board 220, a first heat source 230, a second heat source 240, a liquid cooling device 250, and a windshield 260. The circuit board 220 is disposed on the casing 210. The first heat source 230 and the second heat source 240 are disposed on the circuit board 220. The liquid cooling device 250 is in thermal contact with the second heat source 240 such that the heat energy generated by the second heat source 240 is carried away from the servo host 20 via the liquid cooling device 250. Further, the heating power that the first heat source 230 can generate is lower than the heating power that the second heat source 240 can generate. The liquid cooling device 250 moves the tropics generated by the second heat source 240 having a higher heating power, and the airflow generated by the fan module 30 only needs to travel the tropical heat generated by the first heat source 230 having a lower heating power, thereby saving Electrical energy. The first heat source 230 is, for example, a south bridge, and the second heat source is, for example, a north bridge or a central processing unit, but is not limited thereto.

The wind shield 260 is disposed on the casing 210 and covers the second heat source 240 to serve the servo An air-cooling space 280 and a liquid-cooling space 290 are distinguished in the main unit 20. The air cooling space 280 is carried by the fan module 30 to remove the thermal energy generated by the first heat source 230 disposed in the air cooling space 280 away from the servo host 20, and the liquid cooling space 290 is provided by the liquid cooling device. 250 is to carry thermal energy generated by the second heat source 240 placed in the liquid cooling space 290 away from the servo host 20.

A more detailed description of how the fan module 30 dissipates the air-cooled space 280 will be described below. In this embodiment and some other embodiments, the casing 210 includes a bottom plate 212 and two side plates 214 opposite to each other. One side plate 214 has an air inlet 216, and the other side plate 214 has an air outlet 218. The air inlet 216 and the air outlet 218 correspond to the first heat source 230, respectively. Therefore, when the fan module 30 is in operation, a gas flows into the servo host 20 from the air inlet 216, and exchanges heat with the first heat source 230 in the air-cooling space 280, so that the heat generated by the first heat source 230 is carried away by the gas. And is taken away from the servo host 20 via the air outlet 218.

How the liquid cooling device 250 can carry the thermal energy generated by the second heat source 240 away from the servo host 20 will be exemplified in the following paragraphs. In this embodiment and some other embodiments, the liquid cooling device 250 includes a pump 252, a liquid cooling circuit 254, a heat exchanger 256, and a coolant. Wherein, when the pump 252 is in operation, the pump 252 applies a pressure to the connected liquid cooling line 254 such that the coolant in the liquid cooling line 254 flows along the liquid cooling line 254. Wherein, the liquid cooling circuit 254 passes through the wind shield 260 to be in thermal contact with the second heat source 240. When the liquid cooling line 254 is in thermal contact with the second heat source 240, the cooling liquid flowing through the second heat source 240 absorbs the thermal energy of the second heat source 240. Therefore, the temperature of the endothermic coolant may rise or even vaporize. Then, along the coolant The liquid cooling line 254 flows through the heat exchanger 256. In heat exchanger 256, the coolant is subjected to another heat exchange with heat exchanger 256. The coolant then returns to a lower temperature liquid state, and the heat energy is discharged from the server 5 by the heat exchanger. Therefore, the liquid cooling device 250 can discharge the heat generated by the second heat source 240 out of the server 5 by the continuous circulation and flow of the coolant in the liquid cooling line 254.

When the fan module 30 is in operation, the fan module 30 causes a gas to flow through the servo host 20. Wherein, because the wind shield 260 covers the second heat source 240. Therefore, most of the airflow generated by the fan module 30 is used to dissipate heat from the first heat source 230 in the air-cooled space 280. In the embodiment, the airflow generated by the fan module 30 does not have to exchange heat with the second heat source, so the airflow is not compared with the technology of cooling the space in the entire servo host 20 by using the airflow generated by the fan module 30. The server and the servo host disclosed in the embodiment have better heat dissipation efficiency, and can maintain the low temperature and have better heat exchange capability. On the other hand, the liquid cooling device 250 only needs to dissipate heat from the second heat source 240 in the liquid cooling space 290. Therefore, it is only necessary to contact the pipeline of the liquid cooling device 250 with the second heat source 240 in the design of the pipeline. It is not necessary to touch all the heating elements. Compared with the prior art, the pipeline of the liquid cooling device 250 must be in contact with each heating element, which is complicated in the design of the pipeline. Therefore, the server and the servo host disclosed in this embodiment are also simpler in designing the pipeline than the prior art.

Please refer to "3A" and "3B", "3A" is a schematic view of the servo host and deflector of "1" and "3B" is "1" Schematic diagram of the servo host, the deflector and the fan module. In this embodiment and some other embodiments, the servo host 20 further includes a third heat source 232 disposed on Between the second heat sources 240. Since the air moves in a direction in which the resistance is small, when the fan module 30 is in operation, the flow rate of the generated airflow through the first heat source 230 is much larger than the flow rate through the third heat source 232, and thus is generated in the third heat source 232. Only a small portion of the thermal energy is carried away by the airflow, so that the heat dissipation efficiency of the third heat source 232 is not good. In order to improve the problem, in the embodiment and some other embodiments, the servo host 20 further includes a baffle 270 disposed in the casing 210. By the wind shield 260 and the baffle 270, the air from the air inlet 216 is guided to the third heat source 232 to carry the heat energy generated by the third heat source 232 away from the servo host 20.

In addition to directing the airflow to the third heat source 232 between the second heat sources 240, the deflector 270 has the effect of collecting wind in the embodiment and some other embodiments. In this embodiment and some other embodiments, the servo host 20 further includes another fourth heat source 234 and another deflector 272. The fourth heat source 234 is disposed on the circuit board 220. The deflector 272 is disposed in the casing 210. The deflector 272 forms a tunnel-like structure in the fourth heat source 234. Therefore, the deflector 272 can concentrate the airflow generated by the fan module 30 and flow the airflow along the deflector 272 through the fourth heat source 234 to The heat generated by the four heat sources 234 is carried away from the servo host 20, thereby improving the heat dissipation efficiency of the servo host 20.

In order to further improve the heat dissipation efficiency of the servo host and make the design of the liquid cooling device simpler, the air cooling space and the liquid cooling space can be further planned. Please refer to FIG. 4, which is a plan view of a servo host according to another embodiment of the present invention. Since this embodiment is similar to the embodiment of FIG. 1, the same reference numerals denote the same or similar elements as the embodiment of FIG. 1, and therefore only The difference is explained. In this embodiment and some other embodiments, the servo host 20 ′ is configured as a plurality of air-cooled spaces 280 ′ and a plurality of liquid-cooled spaces 290 ′, wherein the first heat source 230 ′ having a lower heat-generating power is disposed in the air-cooled space 280 . ', the second heat source 240' having a higher heating power is disposed in the liquid cooling space 290', and the wind shield 260' covers the second heat source 240'. Thereby, a plurality of air ducts are planned in the servo host 20'. Therefore, the airflow generated by the fan module 30' only needs to flow along the linear air passage of the air-cooling space 280' to flow through the first heat source 230', and it is not necessary to add a deflector to guide the airflow to the first heat source 230' for heat dissipation. Therefore, the flow path of the air flow is further shortened, so that the heat dissipation efficiency of the servo host 20' can be further improved. In addition, the design of the air duct also makes the pipeline of the liquid cooling device 250' simpler, for example, the number of times of avoiding the pipeline from the first heat source 230' or passing through the windshield 260', etc., The piping of the liquid cooling device 250' is also more convenient to set up.

According to the server and the servo host disclosed in the embodiments of the present invention, since the windshield covers the second heat source to distinguish the air cooling space and the liquid cooling space in the servo host, the flow rate of the gas flowing through the first heat source is greater than the gas flow rate. The flow rate of the second heat source, and therefore the airflow flowing through the first heat source is not easily heated by the second heat source. In this embodiment, the heat dissipation efficiency of the airflow to the first heat source can be improved. In addition, since the heat of the second heat source covered by the windshield is excluded by the liquid cooling device, the embodiment can also remove the heat of the second heat source without causing an increase in the temperature of the airflow flowing in the casing. . The servo and the servo host of the above embodiment have better heat dissipation efficiency than the prior art.

In addition, in some other embodiments, the servo host is planned to be air-cooled And several liquid cooling spaces to plan several air ducts for the servo host. Therefore, the flow path of the airflow generated by the fan module can be shortened, thereby improving the heat dissipation efficiency of the servo host. In addition, the design of the liquid cooling circuit of the liquid cooling device will be simpler.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The scope of patent protection of the invention is subject to the definition of the scope of the patent application attached to this specification.
