Description

Technical Field

[0001] The present invention relates to the technical field of radiators, in particular to a siphon radiator with a self-collecting gas evaporator designed in a refrigerant two-phase change. Background Art

[0002] The design of the evaporator of a thermosyphon radiator is related to the efficiency of the internal liquid converting into gas after absorbing the heat of the chip. We call this the evaporation efficiency. This is often the most important issue for each heat dissipation factory in designing a thermosyphon radiator. The design of this evaporation efficiency not only changes the internal structure of the evaporator, but also requires the comprehensive coordination of the external structure, piping, smooth condenser circuit, etc., in order to achieve a high-efficiency heat dissipation circuit. Traditional evaporator structures are mostly designed in a flat and square form. Although this design seems easy to manufacture and design, even if a high evaporation efficiency internal structure is used, due to the large impedance due to the many right angles on the path, it is less likely to transfer a large amount of steam to the steam outlet quickly, which reduces the efficiency of collecting gas. Due to the increasing demand for high-wattage heat dissipation, a radiator with an evaporator structure that collects gas has been developed, and heat exchange is performed in an air-cooled manner. It is expected that the heat dissipation of the current traditional evaporator structure can be greatly improved.

[0032] As attached Figure 1-8 Shown

[0033] The present invention provides a self-collected gas evaporator designed in a refrigerant two-phase change siphon radiator, including a self-collected gas evaporator structure and a condensation structure. The self-collected gas evaporator structure is vertically fixed with at least one gas-liquid transmission component. Through the arrangement of the gas-liquid transmission component, the steam generated inside the self-collected gas evaporator structure can directly enter the gas-liquid transmission component, and in the gas-liquid transmission component, the condensation structure is used to perform heat exchange and convert it into liquid, and then flow back to the self-collected gas evaporator structure, thereby shortening the loop of the gas refrigerant to the liquid refrigerant and improving the heat dissipation efficiency. The condensation structure is fixedly installed on the gas-liquid transmission component, so as to assist the gas-liquid transmission component to perform better heat dissipation through the condensation structure. The condensation structure is located above the self-collected gas evaporator structure.

[0034] In this embodiment, the self-collecting gas evaporator structure includes a base 1, an inclined peak cover plate 2 and an inclined inner FIN structure 3, so as to contact the CPU that needs heat dissipation through the base 1. The inclined inner FIN structure 3 and two gas-liquid separators 4 are fixedly installed between the base 1 and the inclined peak cover plate 2. Through the setting of the inclined inner FIN structure 3, the refrigerant can absorb heat and then evaporate and condense after boiling inside the refrigerant two-phase change siphon radiator designed for self-collecting gas, and change from liquid to gas. The inclined inner FIN structure 3 is located between the two gas-liquid separators 4. Through the setting of the gas-liquid separator 4, the gaseous refrigerant is prevented from flowing back. The shape of the gas-liquid separator 4 is the same as that of the inclined inner FIN structure 3.

[0035] In this embodiment, a liquid adding pipe 5 is fixedly installed on the inclined peak cover plate 2, so that the required refrigerant can be added to the refrigerant two-phase change siphon radiator designed from the gas collection evaporator through the liquid adding pipe 5, and can be connected with other external components for use. The liquid adding pipe 5 is connected to the inclined inner FIN structure 3 through the gas-liquid partition plate 4. The setting of the gas-liquid partition plate 4 can prevent the evaporated gas inside the gas collection evaporator structure from entering the liquid adding pipe 5;

[0036] In this embodiment, the gas-liquid transmission component includes a gas-liquid transmission structure 6 and a guide structure 7. The bottom of the gas-liquid transmission structure 6 is fixedly installed on the inclined peak cover plate 2. The gas-liquid transmission structure 6 adopts a microchannel structure so that the gaseous refrigerant rises inside the gas-liquid transmission structure 6 and condenses during the rising process. The top of the gas-liquid transmission structure 6 is fixedly installed with a guide structure 7, and the guide structure 7 is connected to the inside of the gas-liquid transmission structure 6. Through the setting of the guide structure 7, the gaseous refrigerant rising inside the gas-liquid transmission structure 6 can eventually contact the guide structure 7, and the gas-liquid transmission structure 6 is connected to the inside of the inclined peak cover plate 2;

[0037] In this embodiment, the condensation structure includes a condensation fin group 8 so as to improve the heat dissipation capacity of the gas-liquid transmission structure 6 through the condensation fin group 8. The condensation fin group 8 is fixedly mounted on the gas-liquid transmission component, and the condensation fin group 8 is located above the inclined peak cover plate 2.

[0038] In this embodiment, an inclined cavity 21 corresponding to the shape of the inclined inner FIN structure 3 and the gas-liquid separation plate 4 is provided on the bottom surface of the inclined peak cover plate 2. The inclined inner FIN structure 3 and the gas-liquid separation plate 4 are located in the inclined cavity 21. The gas-liquid transmission structure 6 is connected to the interior of the inclined cavity 21, so that the steam can automatically flow along the inclined structure to the evaporation outlet, greatly improving the input efficiency, and be transmitted to the condensation structure for circulation using the siphon principle.

[0039] In this embodiment, at least one connecting seat 22 is provided on the upper surface of the inclined peak cover plate 2, and the connecting seat 22 is connected to the inclined cavity 21. The bottom of the gas-liquid transmission structure 6 is fixedly installed in the connecting seat 22, and the gas-liquid transmission structure 6 is connected to the connecting seat 22, so as to provide an installation space for the gas-liquid transmission structure 6 through the connecting seat 22, thereby ensuring the stability of the gas-liquid transmission structure 6, and allowing the gas-liquid refrigerant to circulate between the gas-liquid transmission structure 6 and the self-collecting gas evaporator structure.

[0040] In this embodiment, the condensation structure further includes a protective plate 9 so as to protect the condensation fin group 8 through the protective plate 9 . The protective plate 9 is fixedly mounted on the outside of the condensation fin group 8 , and the guide structure 7 is located inside the protective plate 9 .

[0041] In this embodiment, an installation cavity 81 corresponding to the gas-liquid transmission structure 6 and the guide structure 7 is provided on the condensing fin group 8. Through the setting of the installation cavity 81, the condensing fin group 8 can be fitted together with the gas-liquid transmission structure 6 and the guide structure 7. The condensing fin group 8 is installed on the gas-liquid transmission structure 6 and the guide structure 7 through the installation cavity 81.

[0042] In this embodiment, at least two rows of notches 31 are provided on the bottom surface of the oblique inner FIN structure 3. The notches 31 are provided to allow liquid refrigerant to be added to the oblique inner FIN structure 3 through the liquid adding pipe 5. The notches 31 are connected to the gas-liquid separation plate 4 and the liquid adding pipe 5.

[0043] In this embodiment, at least two notches 41 are provided at the bottom of the gas-liquid separation plate 4, and the notch 41 is connected to the notch 31 correspondingly, and the notch 41 is connected to the liquid adding tube 5. Through the setting of the notch 41, it can be blocked by the liquid refrigerant inside the oblique inner FIN structure 3, that is, liquid refrigerant can only be added to the oblique inner FIN structure 3 through the liquid adding tube 5, and the gaseous refrigerant evaporated inside the oblique inner FIN structure 3 cannot enter the liquid adding tube 5 through the notch 41.

[0044] In this embodiment, a slope 11 and a slope 2 12 are respectively provided on the oblique inner FIN structure 3 and the gas-liquid separation plate 4, and grooves 13 corresponding to the gas-liquid transmission structure 6 are respectively provided on the oblique inner FIN structure 3 and the gas-liquid separation plate 4, and the grooves 13 are connected with the notch 1 31. The bottom of the gas-liquid transmission structure 6 is in contact and connected with the grooves 13 on the oblique inner FIN structure 3 and the gas-liquid separation plate 4. Through the design of the slope 11 and the slope 2 12, the steam can be automatically and quickly guided to the evaporation outlet along the inclined structure, thereby greatly improving the input efficiency.

[0045] In this embodiment, the base 1 and the inclined peak cover plate 2 are fixedly connected by at least four fasteners 10 , and the fasteners 10 are evenly distributed at four corners between the base 1 and the inclined peak cover plate 2 .

[0046] It should be noted that the invention of the siphon-type radiator with a self-collecting gas evaporator structure, in addition to utilizing the principle of heat absorption by the change of the two phases of the refrigerant gas and liquid, is based on the concept that the evaporator has an inclined angle design, so that the steam can automatically flow along the inclined structure to the evaporation outlet quickly, greatly improving the input efficiency, and is transmitted to the condensation structure to circulate using the siphon principle. This process does not require the use of any active pump for circulation, and because the pressure of the refrigerant is relatively high when it evaporates, metal brazing technology is also used to solve the high pressure resistance and leakage problems. The inclination angle of the self-collecting gas evaporator structure is not limited to the degree and form, nor is it limited to the number of self-collecting structures, nor is it limited to T-type, REMOTE or tower-type radiators. As long as the evaporator structure has a self-collecting gas structure, it is included in this range, and no shape is limited.

[0047] This design mainly considers the gaseous refrigerant as a fluid, and uses a self-collecting gas structure to greatly reduce the flow resistance and quickly collect the refrigerant gas. After the internal working fluid (refrigerant) absorbs latent heat through phase change, the high-temperature vapor goes up along the inclined structure to the central guide block and then to the condensation structure for heat exchange. The temperature difference between the evaporation end and the condensation end is used to form a siphon circulation heat dissipation mode.

[0048] 1. Tilted evaporator gas working process:

[0049] Step-1. Evaporation: After the CPU heating end absorbs heat, the steam generating device in the evaporator allows the refrigerant (R134a) to absorb heat, and then boils inside the evaporator and evaporates, changing from liquid to gas.

[0050] Step-2. Self-collection of gas: The self-collection evaporator structure automatically and quickly collects a large amount of vapor to the central diversion structure.

[0051] Step-3. Heat transfer: After vaporization, the steam increases in volume, causing a pressure difference. Gas is produced by the evaporator (high pressure, Evaporator). At this time, the steam is transmitted through the pipe to the condensation end (low pressure, Condenser) of the T-type or REMOTE.

[0052] Step-4. Condensation: After the steam passes through the gas-liquid transmission channel and the condensation end, the heat is transferred from the condensation structure to the fins to exchange heat with the cold air and condense into liquid.

[0053] Step 5. Reflux: By gravity, the liquid flows back to the evaporator through the liquid transfer channel, completing the siphon cycle.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
