Abstract

A counter flow radiator includes multiple layered cooling cores configured in series along a first direction that is the same as the direction of airflow used to cool fluid flowing through the counter flow radiator. Heated fluid inputs the counter flow radiator at a first end and flows through each cooling core in a serpentine-like path to the second end of the counter flow radiator, effectively progressing in a direction opposite that of the airflow.

The design of the device, in this context, is particularly relevant to the use of the present invention in relation to the heat generating device for cooling fluid-air heat exchangers for fluid cooling applications. . [Prior Art] = High-efficiency energy-frequency circuits in the field of electronic cooling are used in the field of electronic cooling.

The configuration towel, the traditional button provides a limited size within it. A sufficient cooling solution is provided. Traditionally, a heat sink and a large fan that blows air onto the 5 200847914 heat sink are used, or the integrated circuit is cooled only by blowing air directly onto the circuit board containing the integrated circuit. However, considering the limited free space in the chassis, the amount of air available to cool the integrated circuit, and the space available for conventional cooling equipment such as heat sinks and fans are limited. Closed loop fluid cooling is an alternative to traditional cooling solutions. The closed loop fluid cooling solution is more efficient than the air cooling solution. The closed cooling back ^ • 'the system includes a cold plate for receiving a heat source, a radiator for cooling the heat by the fan, and driving the fluid through the closed loop. One pump. Each group ^ design is usually very complex and requires detailed analysis and optimization of the specific application. ° ''' Figure 1 illustrates the configuration - direction of fluid flow The first conventional light ejector 2. The radiator 2 is configured - a fluid input header 1G, a fluid output header ^ a set of parallel fluid passages 14 through which the heated fluid flows, and a set of thermal couplings to the set of fluid passages 14 The heat sink 16 is cooled. The heated fluid enters the fluid input head 10 and flows into the fluid passage 14. The fluid passage 14 and the cooling fins 16 are made of a paving material, and the fluid of the Mingqiang ship flow channel 14 is transferred to Cooling fins W. The cooling fins are exposed to the airflow for cooling. The airflow is provided in a direction perpendicular to the read flow direction of the flow body channel 14. In this configuration, each fluid channel 14 is exposed to the same temperature airflow. When the fluid temperatures in the fluid passages 14 are the same, the temperature of the air that is lightly interlaced with each fluid is married, and the temperature of the fluid and the temperature of the air are the same for each neon channel. The fluid to be cooled is from the fluid. The passage 14 flows to the fluid head 12 and leaves the radiator 2. Figure 2 illustrates a second conventional modulator 4 that configures the flow of the two directions. The radiator 4 is configured - the first (four) header 2 〇 'one second Fluid Header 22, 6 200847914 2 = and 1 row of fluid passages 24, - a second set of parallel fluid passages 25, and Α;; Ϊ: to the 24th and 2nd sets of fluid passages 25 = heat release > i 26. The first group of Zhao channels 24 touch two Group fluid channel % 2. Read the shipman's first-fluid copper 2G and "the first group of fluids through the fluid header 2G contains - the distributor 28, configured to prevent the input of the fluid" through the first fluid (four) into the first

Work = Γ 25. The fluid passage 24 and the cooling heat sink U are formed by heat transfer to enhance the transfer of heat from the fluid passage 24 to the cooling fins 26. Cooling fins 26 are exposed to the gas stream for cooling. The cold flow system is from the passage 24 _ to the second fluid copper 22 and is guided by the body passage 25. The fluid passage 25 is made of a thermally conductive substance to enhance the % of the cooling sheet from the flow through. Further, with double cooling, the system flows from the fluid passage 25 to the first fluid header 2〇 and away from the injector 4. The dispenser 28 prevents circulation from the fluid passage 2 into the fluid passage 24. In the first conventional radiator 2, air is supplied to the second conventional radiator 4 in a direction perpendicular to the flow direction of the fluid flowing through the fluid passages 24, 25. In this configuration, each fluid channel 24, 25 is exposed to the same temperature gas stream. However, the flow system flowing through the fluid passage 25 is colder than the fluid flowing through the fluid passage 24. Because the air temperature of the airflow interleaved with each of the fluid passages 24, 25 is the same, there is a large difference between the airflow and the fluid flowing through the first set of fluid passages 24 and between the airflow and the fluid flowing through the second set of fluid passages 25. Temperature difference. Therefore, the cooling efficiency of the radiator 4 is not uniform. The effectiveness of the radiator depends on the rate of airflow over the cooling fins, the flow rate of the fluid passage through the 747979414, the surface area on the cooling fins, and the temperature difference between the air and the fluid. A more efficient cooling method is required to cool the integrated circuitry within the electronic device. There is also a need to add a cooling method that limits the cooling efficiency of a given space.

The heat generating device includes, but is not limited to, one or more central processing units (CPUs) mounted on the motherboard, daughter board and/or PC expansion card for managing one or more central processing unit inputs/outputs A chipset, one or more drawing 'and/or one or more physical processing units (ppUs). 200847914

The cooling system can also be used to cool power electronics such as metal oxide semiconductor field effect transistors (m0Sfets), switches, and other high power electronics 7L parts that require cooling. The cold (four) system described herein can lie on any electronic subsystem containing one of the heat generating devices to be cooled. In several embodiments, the countercurrent fluid-to-air heat exchanger is a radiator. As explained herein, a radiator is used as a reference. It should be understood that the reference system is representative of any type of countercurrent fluid _ air heat exchange system unless explicitly referenced to the specific characteristics of the radiant ’. The hot parent converter can receive the heat generated by the heat generating device. In several embodiments, the hot parent exchanger configures fluid passage through which fluid in the cooling circuit can pass. As the fluid passes through the heat exchanger, a heat system is delivered to the fluid, and a heat flow system is output from the heat exchanger and turned to the counterflow radiator. = One or more air converters of the fan are coupled to the counterflow radiator. The heat flow system was input to the counterflow towel. The gas flow provided by the gas-to-air converter is directed to and through the counter-current radiator thereby cooling the fluid passing therethrough. The cooled flow is output from the countercurrent radiator. The third @description contains the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The cooling circuit includes counterflow radiators 3A, a pump 9 and a hot parent 92, respectively, which are coupled via fluids, lines 94, 96, 98. In this configuration, the cooling circuit is coupled to a radiator inlet via fluid line 94 and to a radiator outlet via fluid line 96. It should be understood that this cooling circuit is in use. For example, the pump 9Q can be placed on the inlet side of the countercurrent radiation & 30, except for the outlet side of the third. One or more air converters, such as fans, are shown as being coupled to the counterflow radiator 30 to provide airflow to a suction side of the counterflow radiator 30. Heat exchanger 92 is coupled to heat generating device 1〇2. Any conventional coupling device can be used to couple the heat exchanger 92 to the heat generating device 1〇2. A movable coupling device is used to move and reuse the heat exchanger. An immovable coupling device can be used instead. The heat generated by the heat generating device 1〇2 is transferred to the fluid flowing through the heat exchanger 92. The heated flow system is output from the heat exchanger 92 and is input to the countercurrent radiator 3〇. Although the cooling circuit includes a single heat master 92, the cooling circuit can include more than one heat exchanger in series or in parallel with the heat exchanger 92. In this method, the cooling circuit can be used to cool a multi-heat generating device, wherein the multi-heat generating device is coupled to an early circuit board or distributed to a plurality of circuit boards. The counter-current radiator comprises a multi-layered cooling core arranged in series along a first direction opposite the flow of gas for cooling the fluid flowing through the counter-current radiator. The heated flow system inputs the countercurrent radiator at a first end and flows through the respective cooling cores to the second end of the countercurrent radiator in a layered winding path to effectively advance in the airflow direction. As explained herein, although the counter current radiator may comprise more than two layers of cooling cores, reference is made to a counterflow radiator comprising two layers of cooling cores. A fourth embodiment illustrates a cutaway perspective view of a configuration of the counterflow radiator 30. The countercurrent field is a two-layer cooling core 50, 52, a first, body header 32 and a second fluid header 34 (Fig. 5). As shown in Fig. 4, the eight-deletion-fluid head 34 is shown to show the cooling core 5, 52 and the side view is not cut. Each of the cooling cores 50, 52 includes at least one fluid conduit 38, and at least one of the thermocouples 13 2UU 84/914 coupled to the fluid conduit 38, each of the cooling cores 5, 52.

Deer horned 匕 3 two-layer fluid conduit Deng, and four figures show that the number of more or less ^ | two cooling cores can include the fourth conduit 38 and cooling fin assembly ^ = layer and heat sink assembly layer. The fluid is made from a conductor f that flows through the fluid conduit 38, causing the heat to advance from the fluid conduit %^ to the body conduit 38 material, and the member 36. The fluid conduit 38 can be made from a heat transfer material that is transferred to the cooling fin group. The ... heat sink assembly 36 is the same or different.

Each fluid is a micro-duct 46. Each of the microcatheters 46 is coupled to the first and second bodies 32 by the first end of each of the microcatheters 46 in the heat transfer material tube 38, and the second end of each of the (four) tubes 46 is coupled to the second header 34 ( Figure 5) The calibrated cooling cores 50, 52 form an inspiratory side 31 and an exhaust side 33. One or more fluid inlets 4Q are placed adjacent to the exhaust side 33 of the first fluid header 32. The radiator, such as the counterflow radiator of Fig. 4, encompasses an even number of cooling cores, and one or more fluid outlets 42 (Fig. 5) are placed adjacent to the suction side 31 of the first fluid header 32. If the countercurrent radiator Including a countable number of cooling cores, one or more fluid outlets are placed close to the suction side 31 of the 14 200847914 second fluid head. The first fluid header 32 is configured to direct fluid from the fluid inlet, cooling the core to the micro The first end of the catheter *, and the more the material enters the fluid outlet 42 from the first end of the microcatheter 46 of cooling = 52 (the fluid header 32 of Figure 5 is also configured to prevent fluid from the fluid inlet 4 〇缄 0), ° Core 50 enters, and flows directly to the fluid.

For example, if -, person, TO, add the corresponding number to add the distributor to the i cold: two or two t cores in series to buy a ^ two fluid header, called the field; ^ and the additional cooling core between the first end of the fluid bypasses the microcatheter in the cooling core% Second, do not add another - allocate 1! ^, get '46 second creep. In this example, cool the core 52 ° ° to the ground The first - _ 15 200847914 component that can receive fluid from the axis of the guide 46 is expanded to be chilled with the third, thereby causing the flow cooling conduit 46 to be first coupled to the third cooling core towel = the first end fluid label of the dip tube 46 is not configured with a fluid outlet 42 4 in this example 'this first - the second fluid header.

For a 丄t knife configuration that prevents fluid flow: a header assembly in which two adjacent header assemblies are: a two-part dispenser. Figure 5 shows the countercurrent radiation containing the direction of air and fluid flow crying 30 cut, the top and bottom diagrams are not. The heated flow system is wheeled into the reverse radiant radiator 30 at _ population 4 (). The fluid inlet 40 is placed on the exhaust side of the face. The body first flows to the Wei side of the county, 33 _ cold _ ^, which in this case = cooling core 5G. The fluid flows through the cooling core 5 wiper tube 38 along the second direction in the negative y direction in this example. #纽_ When cooling the fluid conduit 38 in the core 5', the fluid is directed along the first direction in the positive direction of this example, via the second fluid header 34 to the fluid conduit 38 in the cooling core & . The fluid in this example reverses flow through the fluid conduit 38 in the cooling core 52 in the second direction of the positive and negative y directions. As the fluid exits the fluid conduit 38 in the cooling core 52, the fluid is directed away from the fluid outlet 42 via the second body header 32. In this method, when proceeding along the direction of the ground, the fluid flows in the direction in which the layers are wound, and travels back and forth along the second direction. As the heated fluid flows through the fluid conduit, the thermal system moves from the fluid to 16200847914 to the cooling fins. It starts to feed, and when it flows "cold heart 50, when it flows through the cooling core, it _ cools, so that the coldest flow system is from the countercurrent two = two: the fluid is heat. The system is _ fluid, and Hottest stream

The air flow at the inlet 30 is outputted at the suction side 31 by the first side minus 33. In this method, the airflow is directed in the opposite direction of the second direction, that is, the negative enthalpy direction passes through the cooling cores 5G, 52. When the air = over-cooling heat (10)%, the secret from the cooling of the health group ^ spears to the gas. Therefore, the deeper the air passes through the countercurrent light radiator 3, the more air is cooled, the coldest air is the air at the suction side 31 of the countercurrent light radiator 30, and the hot air is at the exhaust side 33 of the countercurrent radiator. Air output. Because when the air at the exhaust side is transferred from the suction side to the fluid from which the exhaust side has passed, the flow system at the suction side is exposed to fluid at the exhaust side. Cold air. Each fluid conduit 38 includes a plurality of microcatheters 46. In some embodiments, each of the microcatheters 46 are isolated from one another, and the fluid flowing through each of the microcatheters 46 is not mixed with the fluid flowing within each of the other microcatheters 46. Figure 8 illustrates a first fluid conduit configured to isolate each microcatheter 46 from each other, an example of the top and bottom. In this example, as the fluid exits the microcatheter 46, the flow system mixes at the fluid heads such as the fluid header 34. The microcatheter 46 is made of a thermally conductive material that promotes heat transfer through the fluid flowing through the microcatheter 46. When there is a fluid and air temperature gradient from the suction side to the exhaust side of the countercurrent radiator, the fluid conduit 38 of each cooling core also has a fluid and air temperature gradient of 200847914. The fluid flowing in the microcatheter closer to the exhaust side of the countercurrent radiator interacts with the hotter air than the fluid flowing in the microcatheter closer to the inspiratory side of the countercurrent radiator. If the fluid conduit 38 is configured with a separate microcatheter 46 as shown in Figure 8, a fluid temperature gradient exists between the inspiratory side and the exhaust side within a given fluid conduit. In several embodiments, the fluidic conduit 38 is configured as a single channel without a microcatheter. In this configuration, the fluid is not isolated to a position on the inspiratory side and the exhaust side, and when the fluid flows through the fluid conduit 38, the fluid from the inspiratory side to the exhaust side is mixed. Although sufficient mixing may or may not completely eliminate the fluid temperature gradient between the inspiratory side and the exhaust side, the fluid temperature gradient in a single channel configuration is less than the fluid temperature gradient in a separate microcatheter configuration. A disadvantage of this single channel configuration is the reduction of the rate of heat transfer between the fluid and the fluid microtubes relative to the microcatheter configuration. Because of the large thermal transfer surface area of all of the microcatheters 46, the surface area of the microcatheters 46 can enhance the rate of thermal transfer as compared to the single channel configuration. In an alternative configuration, each microcatheter is configured to match a side opening adjacent the side opening of the microcatheter, thereby facilitating mixing of the microcatheter as fluid flows through the fluid conduit. Figure 9 illustrates a second fluid conduit configured to allow each of the microcatheters 46 to promote fluid mixing, as shown in the upper and lower figures. Each microcatheter catheter is open. Adjacent to the microcatheter, you are configured to match the microcatheter opening so that fluid flowing through the adjacent, microcatheter 46 can be mixed through the microcatheter opening 48. The position of the microcatheter opening 48 as illustrated in Figure 9 is merely illustrative. The number and location of the micro-tube openings can be configured in any mode to achieve the desired fluid mixing effect. 200847914 The microcatheter configuration reduces the fluid conduit _ rhyme temperature gradient relative to the independent microcatheter configuration. Fine, if the number of microcatheters in the microcatheter configuration and the open microcatheter configuration is the same, the microcatheter surface area in the open microcatheter configuration is reduced relative to the independent microcatheter configuration. This reduction in surface area reduces the rate of thermal transfer between the fluid and the microcatheter. To increase this surface area, the fluid conduit can be configured with a larger number of microcatheters. A fluid conduit comprising an open microcatheter is configured to have the same surface area as a corresponding fluid conduit with a separate u' tube to increase the micro-turn number 1 with an opening. Typically, this surface area for thermal transfer can be adjusted in this manner regardless of whether the microcatheter is configured with a separate microcatheter or an open microcatheter. Typically, the temperature difference between the input fluid temperature at the exhaust side and the input air μ at the inspiratory side limits the thermal efficiency of the countercurrent radiator. The foldback of each added cooling core is reduced. As more cooling cores are added, the cooling core temperature difference (the difference between the fluid/JEL degree and the air temperature input to the cooling core) of each cooling core in the system is reduced. Therefore, even if the efficiency of the countercurrent radiation is increased (to the maximum value of the temperature difference of the system), each addition of the cooling core reduces the efficiency of each cooling core. The thermal efficiency of the countercurrent radiant can be adjusted by the flow rate of the fluid through the countercurrent radiator. Because the fluid is exposed to heat transfer occurring within the countercurrent radiator for a longer period of time, the flow rate provides the input fluid temperature and output, and the slower the temperature difference between the larger fluids. However, it is also necessary to determine the fluid flow rate and to balance the fluid flow rate required to optimize the heat transfer occurring in the heat exchanger, wherein the heat system is transferred from the heat generating device to the fluid. Typically, the fluid flow rate can be optimized to achieve the desired system thermal performance, 19 200847914 and/or the expected cooling core temperature differential for each cooling core. The countercurrent radiator is described above by cooling the heated fluid. Specifically, the countercurrent radiator can receive the heated fluid as an input, cool the heated fluid within the radiator, and output a cooling fluid. The heated flow system is cooled using a fluid-to-air cooling method in which an input gas stream passes through the radiator, and heat from a fluid flowing within the radiator is transferred from the fluid to the radiator material and to the radiator material. The air on it. Thus, the airflow from the 5 Xuan Xingzuo is hotter than the airflow that is turned into the radiator. In an alternative embodiment, the countercurrent radiator is configured to cool heated air. In this alternative embodiment, a cold flow system such as a coolant is introduced into the countercurrent radiator, and the input air passes through the radiator. The heat is transferred from the input air to the cold fluid flowing through the radiator. As such, the airflow exiting the radiator is cooler than the airflow entering the radiator. The flow system output from the radiator is hotter than the fluid input to the radiator. _ Figure 10 illustrates a reflow radiator of Figure 5 reconfigured to cool an input air stream. A cold flow system is input to the counterflow radiator at the fluid inlet 40. The cold fluid flows through the cooling cores 50, 52 and is output via the fluid outlet 42 in a manner similar to that illustrated in FIG. The heated air stream is directed to the countercurrent striker at the suction side 31. As the gas stream passes through the cooling cores 52 and 5, the heat is transferred from the gas stream to the cold fluid passing through the cooling cores 52 and 50. Cooling air is output from the counterflow radiator at the exhaust side 33. The heated flow system is output from the countercurrent radiator at the fluid outlet 42. The above is based on the "backflow" of the suction side of the injector and the fluid inlet. The configuration method is _ counter-mirror. Instead of the actual closing towel, the transmitter is configured as parallel flow, or "co-flow" by 200847914. Wherein the direction of fluid flow through the injector or the direction of gas flow through the radiator is opposite to the countercurrent illuminator. In particular, in this alternative embodiment, the 'fluid inlet and the gas venting side are located at the radiation. On the same side of the radiator, the fluid outlet and the gas flow side are located on the same side of the radiator.

Figure 11 illustrates a fifth-figure lighter that is reconfigured to flow simultaneously. The heated fluid is introduced into the parallel flow radiator at the fluid inlet 40. The heated fluid flows through the cooling cores 50, 52 and exits via the fluid outlet 42 in a manner similar to that illustrated in FIG. The airflow is introduced into the radiator at side 33. As the gas stream passes through the cooling cores 50, 52, the heat is transferred from the heated fluid to the gas stream passing through the cooling cores 52 and 50. The heated air is output from the radiator at side 31. A cooling flow system is output from the radiator at a fluid outlet 42. Like the counter current radiator of Fig. 10, the parallel flow radiator of Fig. 11 can be configured to cool the heated air. In this alternative embodiment, a cold flow system is input to the parallel flow radiator and input heated air is passed through the radiator, wherein the air suction side is located on the same side of the radiator as the fluid inlet. Heat is transferred from the heated air to the cold fluid flowing through the radiator. As such, the airflow exiting the radiator is cooler than the airflow entering the radiator. The flow system output from the injector is hotter than the air flow to the radiator. - The present invention has been embodied in a specific embodiment that incorporates the details of the operation of the g-keys and the principles of operation.
