Description

Technical Field

[0001] This invention relates to heat transfer, and more particularly to a liquid cooling pump unit. Background Technology

[0002] During the operation of electrical and electronic components, devices, and systems, the heat generated by the Central Processing Unit (CPU), processing unit, or graphics card must be dissipated quickly and efficiently to maintain operating temperatures within the manufacturer's recommended range, even under challenging operating conditions. As the functionality and usability of these components, devices, and systems increase, their power demands also rise, further increasing the need for cooling.

[0003] Several technologies have been developed for dissipating heat from electrical and electronic components, devices, and systems. One such technology is a liquid cooling system. In this system, a water-cooled unit makes thermal contact with the components, devices, and / or systems to remove heat. Then, a working fluid circulating within a cooling loop system containing the water-cooled unit flows through a rotor assembly unit, thereby removing heat from the water-cooled unit. Heat is transferred from the heat source to the water-cooled unit, from the water-cooled unit to the working fluid, and then from the working fluid to the surrounding environment via a radiator.

[0004] Generally, the maximum operating temperature of electrical and electronic components, devices, and systems is specified, and a suitable liquid cooling system, depending on the water-cooling unit, radiator, and pump unit, is available. In addition to the working fluid characteristics, impeller design, and motor speed, pump efficiency also depends on head and flow rate. Given the same water-cooling unit and radiator, when the required head exceeds the specifications of a single pump, a larger, heavier new pump or more than one pump is needed, increasing cost. When the horizontal or vertical positioning of the pump negatively affects pump efficiency, a new pump that is not negatively affected by the required positioning is needed, also increasing cost. Given the same pump unit and radiator, when the required heat source area changes, a new pump with the required heat source area is needed to remove heat, increasing cost. In all cases, one or more new pumps are required, and pump specifications lack variability in terms of easy interchangeability of components over time and the required installation components, as well as customization.

[0092] The following describes various principles of liquid cooling systems with specific examples of water-cooled units and rotor assembly units, including configurations and examples of water-cooled units, pump units, and baffles that embody innovative concepts. More specifically, but not exclusively, the principles of this innovation are described with reference to selected examples of water-cooled caps and cavities, and well-known functions and constructions are not described in detail for the sake of brevity and clarity. Nevertheless, one or more of the disclosed principles can be incorporated into various other embodiments of water-cooled caps and cavities to achieve any of a variety of desired results, characteristics, and / or performance criteria.

[0093] Therefore, liquid cooling pump units with different properties from the specific examples discussed herein can embody one or more innovative principles and can also be used in applications not described in detail herein. Accordingly, embodiments of liquid cooling pump units not described in detail herein also fall within the scope of this disclosure, as will be apparent to those skilled in the art upon reading this disclosure.

[0094] The exemplary embodiments disclosed herein pertain to a liquid cooling system in which a water-cooling unit forms thermal contact with electrical and / or electronic components, devices, and / or systems to remove heat. A working fluid, circulating within a cooling loop system and connected to the water-cooling unit via a fluid conduit, flows through the water-cooling unit via a pump unit, removing heat. The heated working fluid exits the liquid cooling system and can be input to a radiator. Next, the heated working fluid can flow to and through the radiator, whereby the radiator may have multiple heat dissipation fins to increase heat dissipation. Then, the working fluid can flow from the radiator back to the variable liquid cooling system to restart the cooling cycle. Although the cooling cycle includes one liquid cooling system, more than one liquid cooling system can be connected to the radiator. In this way, multiple liquid cooling systems and / or a larger heat-generating area can be cooled. Each liquid cooling system can be arranged adjacently in a row or other different configurations to allow design flexibility for configurations specific to particular applications.

[0095] The liquid cooling system can be configured as part of a chassis or electrical or electronic system containing a heat-generating device to be cooled. The liquid cooling system includes at least one liquid-based cooling loop and may further include one or more fans. The one or more fans are connected to the rear end of a radiator via a fastener (e.g., bolts, screws, adhesive material, etc.) located in a structural part of the radiator, delivering air through the radiator to a ventilation chamber or to the outside of the chassis or electronic / electrical system.

[0096] In one embodiment, a liquid-cooled pump unit is provided, comprising a water-cooling unit having a water-cooling assembly, a baffle plate, and a water-cooling cap, and a pump unit having a cavity and a rotor assembly unit. The cavity includes an impeller cavity inlet, a flow regulating disc, an impeller cavity, and an impeller cavity outlet opening. The aforementioned water-cooling cap, the aforementioned baffle plate, and the aforementioned cavity constitute a pump housing assembly. The inlet end and the outlet end are located on the same side and plane of the pump housing assembly. More than one pump housing assembly, more than one water-cooling unit, and more than one pump unit are provided, and they are interchangeable. During operation, working fluid is drawn in from the inlet end through the impeller cavity inlet, enters the impeller cavity via the flow regulating disc, and reaches the multiple arc-shaped blades of the impeller in the rotor assembly unit. From there, the working fluid passes through the impeller cavity outlet opening, the baffle plate, and the water-cooling assembly, and then exits via the baffle plate and the outlet end. The configuration, design, and functional efficiency of the impeller cavity inlet, impeller cavity, and impeller cavity outlet openings, along with the features of the flow regulating disc and the water-cooling cover used to reduce turbulence of the working fluid flowing into the impeller cavity, all contribute to the ability to position the inlet and outlet ends on the same side or plane as the pump housing assembly. More than one pump housing assembly, more than one water-cooling unit, and more than one pump unit can be interchangeably installed within the liquid-cooled pump unit. Similarly, depending on the respective positional configuration of the water-cooled block inlet and outlet through-holes or the cover guide hole and the water-cooled block inlet through-hole, and the installation of the impeller cavity outlet opening and the cavity outlet opening at the water-cooled block inlet and outlet through-holes respectively, or the installation of the impeller cavity inlet and outlet through-holes at the cover guide hole and the water-cooled block inlet through-hole respectively, the pump efficiency will not be negatively affected by the horizontal or vertical position of the pump due to the selection of the pump casing assembly with the highest efficiency, nor will it be negatively affected by the corresponding annular wall and shoulder protrusion or the corresponding annular wall protrusion and shoulder groove respectively.

In some embodiments, the diameter of the rotor assembly unit 202 and the diameter (diameter D) of the cavity 149 are proportionally enlarged from their center in all directions. The diameter (fourth diameter) of the impeller cavity (not shown) of the cavity 149 and the size of one impeller (not shown) of the rotor assembly unit 202 are increased, as an example and not a limitation, thereby increasing the volume of working fluid drawn into the impeller cavity (not shown) through the cavity 149 via the inlet end 191. The third pump unit 202 is interchangeable with the pump unit and is installed in the water-cooling unit 800. The angles of the internal channels of the impeller cavity outlet opening (not shown) and the cavity outlet opening connector (not shown) are modified so that the impeller cavity outlet opening (not shown) and the cavity outlet opening (not shown) are respectively assembled to the water-cooling block inlet perforation 432 and the water-cooling block outlet perforation 429.

[0138] During operation, the working fluid is drawn in from the inlet end 191, enters the impeller cavity (not shown) through the cavity 149 and the water-cooling cover 120, and passes through the funnel-shaped contour wall 112, the guide plate 110, the longitudinal slit perforation 114, and then enters, passes through and flows out of the water-cooling assembly 910 before leaving through the guide plate 110, and finally reaches the outlet end 199.

[0139] In some embodiments, similar elements and features of the liquid cooling pump unit 103, including the water-cooling unit 800 and the pump unit 202, as previously described in embodiments of liquid cooling pump units 100, 101, 102, 500, 701, and 103 having the water-cooling units 300, 600, 800 and the pump units 400, 201, are merely examples and not limitations. For example, the water-cooling cover 120, the baffle 110 and the water-cooling assembly 910, as well as the cavity 150 and the rotor assembly unit 200, will not be described again below for the sake of brevity.

[0140] In some embodiments, the cavities 450, 448, 750, 150, 149, the water-cooling covers 420, 421, 720, 120, the baffles 410, 710, 110, and the rotor assembly unit 200 comprise at least one of metal, plastic, or metal-coated materials, or any combination of the above materials.

[0141] In these embodiments, the water-cooling assemblies 910, 911 comprise at least one of aluminum, copper, aluminum alloy, or copper alloy, or any combination thereof. In some embodiments, the surface of the water-cooling assemblies 910, 911 that is in direct or indirect contact with the heat source may include a plane abutting against a free surface of a heating element.

[0142] In this embodiment, the cavity 922, which has a heat transfer surface feature 921, is rectangular. Those skilled in the art will understand that the shape and size of the cavity 922, including the heat transfer surface feature 921 thereon, can be non-rectangular and of different sizes; the embodiment is not limited thereto.

[0143] In these embodiments, the heat transfer surface features 921 include cut fins; however, the embodiments are not limited thereto. Those skilled in the art will appreciate that alternative forms of heat transfer surface features may also be provided in the cavity 922, as examples and not limitations, such as one or more fins, blades, fan blades, channels, conduits, pins, pillars, caps, slots, protrusions, grooves, perforations, holes, textured surfaces, segmented elements, staggered elements, and smooth surfaces.

[0144] In some embodiments, the liquid cooling system is used to cool each heat-generating device contained within a cover or electrical or electronic system. In alternative embodiments, the liquid cooling system is used to cool only selected heat-generating devices, or only a single heat-generating device, while other heat-generating devices are cooled by other or auxiliary methods.

[0145] The working fluid of the liquid cooling system can be any type of working fluid, such as water, water containing additives (e.g., antibacterial agents), water containing additives to improve thermal conductivity, or other special components, such as non-conductive liquids or liquids containing lubricating additives or anti-corrosion additives.

[0146] Control of the liquid cooling pump unit driven by an alternating current (AC) or direct current (DC) motor is preferably performed through an operating system or similar means, or through the electrical and / or electronic system itself, wherein the electrical and / or electronic system includes measures for the load and / or temperature of one or more processors. Using measurements performed by the operating system or similar system eliminates the need for special devices for operating the liquid cooling pump unit. Communication between the operating system or similar system and the processor used to operate the liquid cooling pump unit can be performed along an established communication link in the system, such as a USB link. Therefore, real-time communication between the liquid cooling system and the liquid cooling pump unit can be provided without any special means of establishing communication.

[0147] Further control strategies utilizing operating systems or similar systems may involve balancing the rotational speed of each liquid cooling pump unit based on the required cooling capacity. If a lower cooling capacity is needed, the rotational speed of each liquid cooling pump unit can be adjusted or limited individually, thereby limiting the noise and wear generated when the motor drives the liquid cooling pump unit.

[0148] In one embodiment, a liquid cooling pump unit 100, 101, 102, 500, 701, 103 is provided, which includes a water cooling unit 300, 301, 600, 800 and a pump unit 400, 201, 202. The water cooling unit 300, 301, 600, 800 includes a water cooling assembly 910, 911, a water cooling cover 420, 421, 720, 120 assembled on the water cooling assembly 910, 911, and a baffle plate 410, 710, 110. The pump units 400, 201, and 202 include cavities 450, 448, 750, 150, and 149 mounted on the water-cooling covers 420, 421, 720, and 120, respectively. These cavities communicate with the water-cooling covers 420, 421, 720, and 120 and are located on opposite sides of the water-cooling assemblies 910 and 911. Each cavity 450, 448, 750, 150, and 149 includes an impeller cavity inlet 451, 751, and 151, a flow regulating disc 489, 789, and 189, an impeller cavity 455, 755, and 155 with a diameter, and an impeller cavity outlet opening 452, 752, and 152. Inlet ends 491, 791, 191 and outlet ends 499, 799, 199 are located on the same side and in the same plane of the pump housing assemblies 700, 900. More than one pump housing assembly 700, 900, more than one water cooling unit 300, 301, 600, 800, and more than one pump unit 400, 201, 202 are provided and are interchangeable. During operation, the working fluid is drawn in from the inlet ends 491, 490, 791, 191, passes through the impeller chamber inlets 451, 751, 151, and enters the impeller chambers 455, 755, 155 through the flow regulating discs 489, 789, 189 to the multiple arc-shaped blades 263 of an impeller 264 in the rotor assembly unit 200. Thus, before leaving through the guide plates 410, 710, 110 and the outlet ends 499, 498, 799, 199, the working fluid flows through the impeller cavity outlet openings 452, 752, 152, guide plates 410, 710, 110 and water cooling units 910, 911.

[0149] The configuration, design, and functional efficiency of the impeller chamber inlets 451, 751, 151, impeller chambers 455, 755, 155, and impeller chamber outlet openings 452, 752, 152, along with the related features of the flow regulating discs 489, 789, 189 and the water cooling covers 420, 421, 720, 120 used to reduce turbulence of the working fluid flowing into the impeller chambers 455, 755, 155, contribute to the ability of the inlet ends 491, 791, 191 and the outlet ends 499, 799, 199 to be positioned on the same side or plane as the pump housing assemblies 700, 900, while providing sufficient differential pressure and working fluid flow rate in the entire liquid cooling pump unit 100, 101, 102, 500, 701, 103. More than one pump housing assembly 700, 900, more than one water cooling unit 300, 301, 600, 800, and more than one pump unit 400, 201, 202 can be interchangeably installed within the liquid cooling pump unit 100, 101, 102, 500, 701, 103. Therefore, when the required head exceeds the specifications of a single pump and / or the required heat source area changes, one or more new pumps are not required. Furthermore, the positions of the water-cooled block inlet perforation 432 and water-cooled block outlet perforation 429, or the cover diversion ports 759, 159 and water-cooled block inlet perforations 732, 132, are configured according to the location of the impeller cavity outlet opening 452 and cavity outlet opening 459 on the water-cooled block inlet perforation 432 and water-cooled block outlet perforation 429, respectively, or the impeller cavity inlet openings 753, 153 and impeller cavity outlet openings 752, 152 are respectively located on the impeller cavity outlet opening 452 and cavity outlet opening 459 on the water-cooled block inlet perforation 432 and water-cooled block outlet perforation 429, respectively. The installation methods of the cover splitters 759, 159 and water-cooled block inlet perforations 732, 732 allow for the selection of the most efficient pump housing assemblies 700, 900. Pump efficiency is not negatively affected by the horizontal or vertical position of the pump, nor by the corresponding annular walls 456, 457 and shoulder protrusions 453, 458, or the corresponding annular wall protrusions 756, 757, 156 and shoulder grooves 653, 758. The convenient interchangeability of the pump housing assemblies 700, 900, related to time and installation components, allows for pump specification variations and provides customization options. Variations between pump housing assemblies may include, for example, but not limited to, changes in the flow rate of the working fluid caused by, for example, an increase in volume of impeller chambers 455, 755, 155 respectively and / or by corresponding annular walls 456, 457 and shoulder protrusions 453, 458, or by corresponding annular wall protrusions 756, 757, 156 and shoulder grooves 653, 758 respectively.
