Abstract

An isothermal equilibrium system takes point sources of heat generated by the operation of heat generating components and spreads the heat throughout the system where the heat may be dissipated. An atomizer for atomizing a liquid coolant, is positioned inside a sealed housing. The atomized liquid coolant is distributed as a thin film over the surface of the heat generating components and the wall of the sealed housing. Heat is transferred from the surface of the heat generating components by vaporization of at least a portion of the thin film of liquid coolant. The coolant vapor condenses on the housing and other cool surfaces and returns to the liquid state. The system heat is then removed from the outer surfaces of the housing using conventional heat transfer mechanisms including free or forced air convection and/or circulation of liquid coolant over the exterior of the housing. If additional cooling is desired, heat exchanger tubes may be included inside the sealed housing. An input liquid or gaseous coolant is circulated through the exchanger tubes. Heat is transferred to the coolant and then conducted away from the heat generating component housing.

Description of the invention (2), in order to guide the heat to an external heat exchanger. However, according to the present invention, the space required for such cooling pipes and heat exchangers is too dense and expensive. Some electronic hardware manufacturers have introduced complex systems that allow liquid coolant in the component case to flow directly around and in contact with the electronic component and back into the case. The cooling liquid is then collected and sent to a heat exchanger / condenser (usually located outside the electronic component guard). These systems are more expensive than E3 and are space-intensive. In addition, these systems involve only single-phase cooling and are not efficient. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (Please read the precautions on the back before filling in this page) Many commercial R & D work on liquid cooling of electronic components and other exothermic parts has been focused on liquid coolants and airflow impacts The relevant range of sun exposure includes: high-speed, narrow single or multiple liquid hip iliac crests directly hit the surface to be cooled. Jet flow balancing may be confused with cold cooling, especially in these two methods, the liquid coolant is discharged from an orifice and flows to the cooled surface; on the impact of the fluid falling air flow and a complete dispersion and atomization In terms of the impact of the liquid Zhao microdrop on a particularly large area, there are many basic and significant differences in the body mechanics and heat transfer mechanism. Jet stream impingement cooling has a number of deficiencies that make it less effective than jet cooling. Because its cooling effect on the surface is not uniform, a higher flow rate is required to obtain a comparable average heat flux, and 焼 $ (transition to a vapor film, which boils with the increase in surface temperature after M). The more obscure-^ is a low 0M 嗔 air cooling, because the heat transfer coefficient is low, in the case of low heat flux, the outer part of a certain area passes through to become a boiling film (thus, Critical heat flux). This phenomenon not only reduces heat removal in these areas, but also increases local surface temperatures. This phenomenon instantly divides a larger increment of -4-this paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm) β 8 36 T a? 87 V. Description of the invention (3) The heat load is placed on Internal areas, but because there is no corresponding increase in heat transfer capacity, these internal areas cannot bear the load. Therefore, the phenomenon of thin film boiling quickly moves inward in the radial direction. In order to achieve a better cooling effect with radon air impact, it has been tried several times to increase the number of air jets, thereby reducing the area of cooling of each air jet. However, it is very difficult to deliver and remove Da Dong fluid neatly and systematically, and these advantages are quickly offset. Therefore, the radon air impact cannot cover the vast area in a dirty way. The following description will clarify: the present invention does not have these disadvantages. Many patents with single-phase, two-gas impulse cooling have been published, including US patents US-4,108,242; 4.912,600; 4,838,041 and 3,844, 3 43. In order to achieve more effective cooling, many effective Research and test of spray cooling effect. The effect has another advantage: the acceptance of the evaporative phase. 0 US patents US-4,643,250; 4,7 90,37 0; 4,643,250; 4,352,392 and 4,967,829 have previously studied in depth the previous technology of evaporative cooling. In general, the previous technology was not successful. Gein ’s traditional clamp is not suitable for practical spray cooling or the spray distance is too large, resulting in inefficiency. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (I read the precautions on the back and then fill out this page) U.S. Patent US-5,220,804 has disclosed an atomized liquid skull, which has been widely distributed and sprinkled against the electronic components to be cooled On the surface, heat is transferred to the coolant by the evaporative phase change method. Vapor and liquid systems accumulate and move into an external condenser. Although this system has the point I of the role of evaporation phase change, the steaming process and condensation process are not performed in the protection of exothermic components. The% body coolant and steam are recycled on the outside of Bangpu and the condenser. .

Description of Invention (7) Scenery " As discussed in the section, circulating liquid systems can add significant weight to the cooling system. The density of the coolant in these systems is usually greater than that of water, which adds a lot to the weight of the entire system. This extra weight is very annoying in dirty electronics and many military applications. As shown in FIGS. 2, 3, 3 A and 5, many atomizers 50 arranged in a custom pattern are located on the leakage plate 100. The leakage plate 100 is properly fixed at the first end of the protective case 20, so several rows of adapters 50 are located between the rows of the component cards 31. The component cards are used to support the electronic components to be cooled. 30 people. As shown in FIG. 3A, the fascia plate 100 is the first component of the spraying chamber 80, and the spraying chamber 80 includes a supporting component 81. As shown in circles 2 and 3, the condensed liquid system after the volumetric liquid-liquid coolant 40 and the evaporation heat transfer process is collected in a storage 60 located at the second end of Huyi 20. Through the supply line 72, Bangpu 70 recirculates the collected coolant 40 to the spray chamber 80, similar to a typical brushless car burning Bangpu. Bangpu 70 is preferably a self-contained DC brushless Bangpu. When the output pressure is at least 20 psi. These Bangpu markets are available. In a preferred embodiment, Bangpu 70, Bangpu motor and motor controller are self-contained in the housing 20. It should be understood that, without departing from the principles of the present invention, the microplate 100 may have many rows and substitutes for parts and components. In addition, instead of setting limits by K, the atomizers 50 can be arranged in different patterns to conform to the rows of exothermic components (Figure 2). As shown in FIGS. 2 and 3, during operation, the liquid coolant 40 in the spray chamber 80 is supplied to each atomizer 50, and a coolant 40 vortex is generated in a vortex chamber.

Description of the invention (8) In Luohua. A second embodiment of the heat dissipation system of the present invention is shown in FIG. In order to achieve further cooling effect, an external cooler 1000 may be installed between the Bangpu 70 and the spraying chamber 80 on the coolant supply line 72. When the thermal load increases due to the increase in the wattage of the electronic component, using the heat dissipation system of the present invention, the K fan 93 forces air through the outer shell 20 and / or the outer cooling fins 22. A third embodiment of the heat dissipation system of the present invention is shown in FIG. Figure 7 illustrates how the present invention uses other methods M to generate a liquid coolant cloud / droplet / particulate. The liquid coolant 40 plus M is stirred with a mechanical stirrer or a paddle stirrer 90 located in the casing 20, collected in a storage tank 60, and dispersed on the exothermic sub-component 30. If further cooling is required, the cooling fins 22 can be surrounded by a housing 29 again. A coolant 400 is circulated through the cooling fins 22. Heat is transferred to the coolant 400 and conducted away from the exothermic component case. As shown in FIG. 8, it illustrates the fourth specific running example of the present invention. An ultrasonic stirrer 92M was used to generate the mists, droplets, and particles of the liquid coolant, and then it was passed through the exothermic components. If further cooling effect is needed, the heat shield tube 20 may include a number of heat exchanger tubes 200. The second® liquid or pneumo hip coolant 300 plus M is circulated via the heat exchanger tube 200. The heat flux is sent to the coolant 300 and is then conducted out as a self-exothermic component. Another advantage of the heat exchanger tube 200 is that more cooling surfaces can be provided, and the evaporated coolant 40 can be condensed on these cooling surfaces and recirculated.
