Description

Technical Field

[0001] This invention relates to the field of radiators, specifically a liquid-cooled radiator. Background Technology

[0002] A radiator is a device used to conduct and release heat, and a cold head is a common component of a radiator.

[0003] In existing technologies, the circulation pump of the cold head is located inside and is difficult to replace. When it fails, it cannot be repaired and can only be discarded, which is very wasteful. The limited space inside the cold head results in limited pump power, and it is also difficult to set up multiple circulation pumps to form a coordinated pump power. In addition, ordinary cold heads only have one liquid path, and users cannot install multiple heat sinks or design the required liquid cooling path sequence for multiple heat sinks. The fixed structure of the cold head makes it difficult to replace parts, which makes it difficult to meet the DIY needs of people today.

[0004] In summary, there is a need to develop a liquid cooling radiator that can easily replace the circulating pump, can install multiple circulating pumps to increase pump power, can connect to multiple heat sinks, and can plan liquid cooling paths to meet users' DIY needs.

The inner side of the circulating pump 4 and the liquid storage chamber 5 are connected by a liquid flow channel 9 consisting of at least one hole opened in the side wall of the liquid storage chamber 5. Compared with the non-detachable built-in pump design, the circulating pump 4 can be completely disassembled and replaced, or individual parts can be disassembled for repair or replacement.

The fluid partition wall 16 set inside the liquid storage chamber 5 can guide the flow direction of the coolant, allowing users to combine multiple cold heads 3 and heat sinks 1 with different fluid partition walls 16 according to their needs to customize the required heat dissipation matrix. The cold head 3 can be connected to multiple heat sinks 1 to improve heat dissipation efficiency.

[0046] By adopting the above technical solution, the rotor 12 and impeller 6 of the circulating pump 4 are immersed in the coolant in the space between the outer wall of the liquid storage chamber 5 and the inner side of the circulating pump housing 10. The stator 11 of the circulating pump 4 drives the rotor 12 and impeller 6 to rotate, pumping the coolant to flow.

Multiple circulating pumps 4 can cooperate to pump and pull or jointly promote the flow of coolant, thereby increasing the flow speed and improving the heat dissipation efficiency.

[0047] Preferably, a sealing ring 15 is provided between the circulating pump housing 10 and the liquid storage chamber 5, and the circulating pump 4 is fixed to the liquid storage chamber 5 by side attachment.

[0048] By adopting the above technical solution, the sealing ring 15 between the circulating pump housing 10 and the liquid storage chamber 5 prevents coolant leakage, ensuring that the circulating pump 4 can pump coolant.

[0053] Preferably, the liquid storage chamber 5 is provided with a fluid partition wall 16, which forms a directional liquid path that guides the flow of coolant.

[0054] By adopting the above technical solution, the coolant flows inside the cold head 3 according to the path planned by the fluid partition 16. Different fluid partitions 16 can be used to design and customize the coolant flow direction under different needs, so as to realize the heat dissipation layout design of multiple heat sinks 1 with a single cold head 3 or multiple cold heads 3 and multiple heat sinks 1 connected in series or in parallel.

[0055] Preferably, the cold head 3 and the conduit 2 are connected by a quick connector. The quick connector 17 of the cold head is located outside the inlet 7 and outlet 8 of the cold head 3, and the quick connector 18 of the conduit is located on the side of the conduit 2 that connects to the cold head 3. The quick connector 17 of the cold head and the quick connector 18 of the conduit are matched.

[0056] By adopting the above technical solution, the conduit 2 can be freely plugged and unplugged from the cold head 3 without worrying about coolant leakage, thus making it convenient for users to DIY different heat dissipation layouts and freely replace or connect multiple cold heads 3 and heat sinks 1.

[0057] This quick connector is a gas-liquid dual-use quick connector. When the conduit 2 is pulled out from the inlet 7 and outlet 8, the quick connector will quickly close to prevent coolant from flowing out.

The cold head 3 and the heat sink 1 are connected in a closed loop. The coolant driven by the circulating pump 4 passes through the outlet 8, the heat sink 1, and the inlet 7.

[0061] By adopting the above technical solution, the circulating pump 4 rotates to pump the coolant, so that the coolant circulates between the cold head 3, the conduit 2, and the heat sink 1.

[0064] By adopting the above technical solution, the parallel liquid storage chamber 23 is provided with at least one liquid inlet compartment and at least one liquid outlet compartment. At least one liquid outlet compartment is connected to at least two flow outlets 8. The flow outlets 8 of the same liquid outlet compartment are internally connected, while the flow outlets 8 of different liquid outlet compartments are not internally connected. Each compartment has a certain space to accommodate coolant. There are guide holes between the compartments. The coolant passes through all the compartments in sequence in the parallel liquid storage chamber 23. The coolant passes through the flow outlet 8 of the same liquid outlet compartment together, so that the coolant can flow out of different outlets at the same time after entering the liquid storage chamber 5. When the cold head 3 is connected to multiple heat dissipation radiators 1, the coolant will enter different heat dissipation radiators 1 at the same time.

[0065] Please refer to Embodiment 3 of the present invention. Figures 9 to 13 :

The compartment connected to the outlet 8 is the liquid outlet compartment. Different liquid outlet compartments are not connected to each other. Each compartment has a certain space to hold coolant. There are guide holes between the compartments. The coolant passes through all the compartments in sequence and flows out of the outlet 8 in sequence in the series liquid storage chamber 22. This realizes that when the coolant enters the liquid storage chamber 5, it flows in a series manner from the inlet to the outlet in sequence. When the cold head 3 is connected to multiple heat dissipation radiators 1, the coolant will enter different heat dissipation radiators 1 in sequence.

[0068] Working principle: The circulating pump 4 is attached to the side of the cold head 3, which allows the circulating pump 4 to be disassembled for maintenance or replacement. Multiple circulating pumps 4 can be installed to increase the flow rate of coolant and improve heat dissipation efficiency through synergistic action. The fluid partition wall 16 inside the liquid storage chamber 5 guides the flow direction of coolant, producing cold heads 3 with different communication structures. Users can combine cold heads 3 with different fluid partition walls 16 to connect multiple heat sinks 1 as needed, and customize the coolant flow path according to their own needs.
