Description

Technical Field

[0001] This utility model relates to the field of computer cooling technology, and specifically to an intelligent heat dissipation system for a hybrid computing device. Background Technology

[0002] With the large-scale application of artificial intelligence technology in fields such as deep learning training, inference, and video image analysis, high-density hybrid computing platforms, which combine multiple CPU and GPU computing units as their core, have become a key infrastructure supporting high-performance computing. In these platforms, the densely stacked hardware architecture of multiple computing units poses a significant challenge to the heat dissipation system, as dynamic fluctuations in task load lead to frequent changes in computing power requirements. Therefore, research is needed on intelligent heat dissipation technologies for high-density hybrid computing platforms.

[0003] Traditional solutions based on fixed thresholds or a single heat dissipation medium struggle to adapt to real-time heat changes, easily leading to issues such as sudden localized heat spikes and delayed heat dissipation. Current mainstream air-cooling technologies increase heat dissipation by boosting fan speeds, but high power consumption and noise limit their applicability. While liquid cooling systems can directionally remove heat, their fixed pipe layouts prevent dynamic adaptation to heat source migration. A common problem with these solutions is the lack of coordinated awareness of the physical distribution of computing units and load conditions, coupled with a lack of predictive cooling strategies, often resulting in resource waste under low loads or performance degradation under high loads. Utility Model Content

[0004] To address the technical problems in existing technologies, such as the lack of collaborative perception of the physical distribution of computing units and load status, and the lack of predictability in heat dissipation strategies, which often leads to resource waste under low load or performance degradation under high load, this utility model provides an intelligent heat dissipation system for hybrid computing devices.

[0008] The input terminal of the power detection module is connected to the power supply. The signal input terminal of the control module is connected to the output terminal of the power detection module and the output terminal of the temperature detection module, respectively. The signal output terminal of the control module is connected to the control terminal of the air-cooled drive module and the control terminal of the liquid-cooled drive module, respectively. The other end of the air-cooled drive module is connected to the positive terminal of the power supply of the air-cooled fan. The negative terminal of the power supply of the air-cooled fan is grounded. The other end of the normally open contact of the liquid-cooled drive module is connected to the power supply of the water pump and the power supply of the water-cooled fan, respectively.

[0009] The beneficial effects of this utility model are as follows: By using a temperature detection module to collect ambient temperature and a power detection module to detect power output, the ambient temperature and power output are used to control the opening and closing of the air-cooling drive module and the liquid-cooling drive module, thereby controlling the power supply to the air-cooling fan, water pump, and water-cooling fan. When the computing power requirement of the high-density hybrid computing platform is high, the number of CPUs and GPUs increases, and the power output at the power supply end increases. When the power output at the power supply end reaches the preset condition, the control module can control all the air-cooling fans, water pumps, and water-cooling fans to start working, thereby achieving a dual cooling method of water cooling and air cooling for the computing platform. Alternatively, when the power output at the power supply end does not reach the preset condition, the control module can control the air-cooling fans to be powered on and all the water pumps and water-cooling fans to be powered off, thereby achieving a dual cooling method of air cooling for the computing platform. Or, when the power output at the power supply end reaches the preset condition, the control module can control the air-cooling fans to be powered off and all the water pumps and water-cooling fans to be powered on, thereby achieving a water-cooling mode for the computing platform. This invention controls the cooling mode based on the physical load power of the computing unit, thereby reducing resource waste and the risk of performance degradation under high load.
