Online cleaning structure and method for liquid cooling system filters

Abstract

An online cleaning structure for a liquid cooling system filter includes: a housing having an internal chamber and a disassembly port, a liquid inlet port, and a liquid outlet port on its circumferential side; a filter having a filter element located in the chamber and removable via the disassembly port; a piping assembly located in the chamber and connecting the liquid inlet port, the liquid outlet port, and the filter; and a flow direction control module adapted to control, in a filtration mode, the coolant input from the liquid inlet port to flow through the filter and then be output from the liquid outlet port; and adapted to control, in a bypass mode, the coolant input from the liquid inlet port to not flow through the filter and instead be output from the liquid outlet port.

Claims

1. An online cleaning structure for a liquid cooling system filter, comprising: a housing having an internal chamber and a circumferentially arranged disassembly port, a liquid inlet port, and a liquid outlet port; a filter having a filter element located in the chamber and removable via the disassembly port; a piping assembly located in the chamber and connecting the liquid inlet port, the liquid outlet port, and the filter; and a flow direction control module adapted to, in a filtration mode, control the flow of coolant input from the liquid inlet port through the filter and out from the liquid outlet port; and adapted to, in a bypass mode, control the coolant input from the liquid inlet port to not flow through the filter and to be out from the liquid outlet port; wherein, The piping assembly includes a first multi-port connector and a second multi-port connector. The first multi-port connector has a liquid inlet, a filter section, and a first bypass section. The liquid inlet connects to the liquid input port. The second multi-port connector has a liquid outlet, a filter section, and a second bypass section. The liquid outlet connects to the liquid output port. The flow control module includes a first valve, a second valve, and two control units. The first valve is located within the first multi-port connector, and the second valve is located within the second multi-port connector. One of the control units... The first valve is connected to switch the connection state of the first multi-port connector. Another control unit is connected to the second valve to switch the connection state of the second multi-port connector. The housing has a top surface with two through holes. Each of the two control units includes an extension and a knob. The two extensions are located in the chamber. One end of the two extensions is connected to the corresponding first valve or second valve, and the other end of the two extensions is located in the two through holes and connected to the two knobs.

2. The online cleaning structure for the liquid cooling system filter as described in claim 1, wherein, Each of the two control units rotates to a first position to switch to the filtration mode of the flow control module. One control unit activates the first valve to switch the liquid inlet section to the filter section but not the first bypass section, while the other control unit activates the second valve to switch the liquid outlet section to the filtered section but not the second bypass section. The two control units rotate to a second position to switch to the bypass mode of the flow control module. One control unit activates the first valve to switch the liquid inlet section to the first bypass section but not the filter section, while the other control unit activates the second valve to switch the liquid outlet section to the second bypass section but not the filtered section.

3. The online cleaning structure for the liquid cooling system filter as described in claim 1, wherein, The knob protrudes from the top surface of the housing and is detachably attached to the circumferential side of the housing or a corresponding extension.

4. The online cleaning structure for the liquid cooling system filter as described in claim 1, wherein, The housing has a front face and a rear face, the liquid inlet and the liquid outlet are located on the rear face, and the disassembly port is located on the front face or the rear face.

5. The online cleaning structure for the liquid cooling system filter as described in claim 1, wherein, The filter includes a housing, a cover, and a pressure relief valve. One end of the housing is liquid-tightly connected to the pipeline assembly. The filter element is housed in the housing. The cover is liquid-tightly connected to the housing. The pressure relief valve penetrates and is connected to the cover.

6. The online cleaning structure for the liquid cooling system filter as described in claim 5, wherein, One end of the filter element is fixedly connected to the cover.

7. An online cleaning method for a liquid cooling system filter, suitable for use with an online cleaning structure for a liquid cooling system filter as described in any one of claims 1 to 6, comprising the following steps: a first switching step: switching the flow control module from the filtration mode to the bypass mode; a disassembly step: removing the filter element from the housing's disassembly port and cleaning or replacing the filter element; an installation step: reinstalling the cleaned filter element or a new filter element from the housing's disassembly port; and a second switching step: switching the flow control module from the bypass mode back to the filtration mode.

8. An online cleaning method for a liquid cooling system filter, suitable for use with the online cleaning structure of the liquid cooling system filter as described in claim 1, and comprising the following steps: a first switching step: switching the flow direction control module from the filtration mode to the bypass mode; a disassembly step: removing the filter element from the housing's disassembly port and cleaning or replacing the filter element; an installation step: reinstalling the cleaned filter element or a new filter element from the housing's disassembly port; and a second switching step: switching the flow direction control module from the bypass mode back to the filtration mode; wherein, In the first switching step or the second switching step, the two control units are first adjusted sequentially or simultaneously to halfway between the first position and the second position, and then sequentially or simultaneously completely switched to the second position or the first position; or the positions of the two control units are adjusted slowly at the same time.

9. An online cleaning method for a liquid cooling system filter as described in claim 7 or 8, wherein, Between the first switching step and the disassembly step, there is an additional pressure relief step: releasing the pressure inside the filter and draining the coolant inside the filter.

10. An online cleaning method for a liquid cooling system filter as described in claim 7 or 8, wherein, Prior to the first switching step, there is a preparation step: placing a desiccant bag adjacent to the lower part of the housing's disassembly port.
