Description
Technical Field
[0001] This utility model relates to the field of heat sink technology, specifically a dual-engine liquid cooler that integrates the principles of thermal insulation and latent heat exchange. Background Technology
[0002] During the operation of electronic equipment, core components continuously generate heat. If this heat cannot be dissipated in a timely manner, it can affect the stability and lifespan of the equipment. Liquid coolers, through direct heat exchange between the liquid and the components, have become one of the most efficient heat dissipation solutions and are widely used in various equipment requiring precise temperature control. Their design often revolves around optimizing heat insulation, airflow guidance, and heat transfer. Through a reasonable structural design, stable heat dissipation of the core area is achieved, adapting to the operational needs of different equipment and ensuring long-term reliable operation.
[0003] Utility model patent CN220545372U discloses a water-cooled radiator and electronic device. This water-cooled radiator and electronic device include a housing with a receiving space and a liquid inlet. The receiving space contains coolant pipes and a distribution section located on one side of the coolant pipes. The distribution section includes at least two distribution channels, one end of which contacts the open side of the coolant pipes, allowing each distribution channel to be opposite to at least one liquid flow path within the coolant pipes. The cross-sectional area of the at least two distribution channels is proportional to the distance between the distribution channel and the liquid inlet. This water-cooled radiator, by incorporating coolant pipes and a distribution section within the housing, allows coolant to enter through the inlet and then flow through the distribution section. The distribution channels closer to the inlet have smaller cross-sections, resulting in greater resistance to the coolant, while the distribution channels farther from the inlet have larger cross-sections, resulting in less resistance to the coolant. This ensures that the coolant flow rate and volume in each liquid flow path are similar, leading to more uniform heat dissipation and enhanced cooling effect.
[0004] The water-cooled radiator and electronic equipment have their casings in direct contact with the internal environment. When high temperatures are generated inside the equipment due to other components, heat can easily be conducted through the casing to the containment space, causing the ambient temperature around the coolant pipes to rise. Furthermore, the coolant pipes not only have to cope with the heat absorbed by the heat source themselves, but also have to resist the intrusion of hot air from the outside, increasing the heat dissipation load. At the same time, when the internal temperature of the equipment rises and the sensible heat exchange efficiency is insufficient, there is a lack of auxiliary cooling power that can be activated. It can only passively withstand the interference of the ambient temperature and cannot actively compensate for the heat dissipation capacity. As a result, the heat dissipation stability is easily affected by the internal temperature of the equipment and it is difficult to adapt to the dynamic changes in the internal temperature of the equipment. In view of this, we propose a dual-engine liquid cooler that integrates the principles of insulation and sensible and latent heat exchange. Utility Model Content
[0005] The purpose of this invention is to provide a dual-engine liquid cooler that integrates the principles of thermal insulation and sensible-latent heat exchange, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A dual-engine liquid cooler integrating the principles of thermal insulation and latent heat exchange includes a housing, on which a heat-conducting component is disposed. The heat-conducting component is used to directly exchange heat with the parts. A heat exchange component is connected to the heat-conducting component, which is used to exchange heat with the heat-conducting component. The top of the outer shell is fitted with a top cover, and a through pipe is connected to both the left and right sides of the top of the top cover. The heat-conducting assembly includes a water pump located outside the housing and attached to the surface of the part, and a pair of liquid collection seats sleeved at the bottom of the inner side of the housing. The input and output ends of the water pump are connected to water pipes, and the ends of the two water pipes are respectively connected to the two liquid collection seats. A base is installed at the bottom of the water pump. Several flat heat-spreading pipes with hollow flow channels are connected between the two liquid collection seats. The water pump, the water pipes, the liquid collection seats and the heat-spreading pipes form a closed water circulation loop. The heat exchange assembly includes a top seat and several bottom sleeves located below the top seat. Several heat pipes are embedded between the bottom end of the top seat and the bottom sleeves. Several bottom sleeves are respectively inserted between two adjacent heat exchange pipes. Several cooling plates are attached to the top of the top seat.
[0007] Preferably, an inner shell is provided inside the outer shell, and a heat-insulating interlayer is filled between the outer shell and the inner shell; In this configuration, the inner shell works in conjunction with the heat insulation interlayer to prevent high internal temperatures from being conducted through the outer shell to the inner shell, thus maintaining a stable temperature in the core heat dissipation area and reducing the interference of external temperatures on heat dissipation.
[0008] Preferably, a fan is installed at the bottom of the top cover, and the fan is shielded below the connection end between one of the through pipes and the top cover. When the fan is working, the outside air forms an airflow channel between the two through pipes. In this setup, the fan drives air to flow along the airflow channel, which can expel the heat in the upper space of the casing through the pipes, helping to dissipate the heat from the top mount and the cooling fins, and maintaining the temperature balance of the upper heat dissipation area.
[0009] Preferably, the outer shell has clearance holes on both the left and right sides, the clearance holes penetrating the inner shell and the heat insulation layer, and the outer end of the liquid collection seat has a threaded hole for installing the water pipe, the position of the threaded hole corresponding to the position of the clearance hole; In this setup, the vent hole provides a passage for the water pipe to pass through.
[0010] Preferably, the base is made of pure copper, and a flexible heat-conducting sheet is attached to the bottom surface of the base; In this setup, the pure copper base can quickly transfer heat from the surface of the component, while the flexible heat-conducting sheet can adapt to the tiny bumps and depressions on the surface of the component, filling the gap between the base and the component and improving the heat transfer efficiency between the two.
[0011] Preferably, the bottom end of the top seat is integrally formed with a plurality of heat-conducting seats, the number of heat-conducting seats is equal to the number of the bottom sleeve seats and their positions correspond one-to-one, and the top end of the heat pipe is embedded in the side surface of the heat-conducting seat. In this setup, the one-piece heat-conducting base reduces heat transfer loss and corresponds to the position of the bottom sleeve to ensure precise connection of the heat pipe; the heat pipe is embedded in the side surface of the heat-conducting base, reducing contact gaps and helping the heat pipe condenser end to release heat efficiently.
[0012] Preferably, the heat pipe has a flat U-shaped tubular structure, the bottom of the heat pipe is embedded in the side wall of the base, the outer surface of the heat pipe is flush with the side surface of the base, two heat pipes are symmetrically installed on each base, a filler plate is filled between the base and the side wall of the heat spreader, and the gap between the bottom of the heat pipe and the heat spreader is filled by the filler plate. In this configuration, the flat U-shaped structure increases the contact area between the heat pipe and the base and heat-conducting seat, shortening the flow path of the working fluid; the two symmetrically installed heat pipes evenly distribute the heat of the base; and the filler plates fill the gaps to ensure efficient heat transfer to the evaporation end of the heat pipe.
[0013] Preferably, a rectangular sleeve plate is fitted and fixed at the outer periphery of the top seat. The outer periphery of the sleeve plate is in contact with the inner wall of the inner shell. The sleeve plate divides the interior of the inner shell, so that the bottom seat, the heat pipe and the liquid collection seat located at the bottom are isolated inside the outer shell. The space located at the upper part of the sleeve plate is connected to the outside through the through pipe. In this setup, the inner shell is separated by a partition to prevent hot air from flowing between the upper and lower areas; the lower heat dissipation core area is isolated to reduce hot air interference inside the device; and the upper space is connected to the outside, allowing the fan to drive airflow to expel heat.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This dual-engine liquid cooler, which integrates the principles of thermal insulation and latent heat exchange, forms a thermal barrier through the inner and outer double shells and thermal insulation interlayer. This can prevent the high temperature inside the equipment from being conducted to the core heat dissipation area. By using a sleeve plate to separate the inside of the inner shell, hot air inside the equipment is prevented from entering, so that the heat dissipation components only need to deal with the heat of the heat source, thus reducing the heat dissipation load. 2. This dual-engine liquid cooler, which integrates the principles of thermal insulation and sensible and latent heat exchange, forms a dual-engine mode through the sensible heat exchange of the set heat-conducting components and the auxiliary heat dissipation of the cooling chip. When the internal temperature of the equipment rises and the sensible heat efficiency is insufficient, the cooling chip can be activated to improve the heat dissipation capacity, offset the temperature interference, and adapt to the scenario of dynamic changes in internal temperature.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figures 1-6The dual-engine liquid cooler, which integrates the principles of thermal insulation and latent heat exchange, includes a housing 100. A heat-conducting component 200 is installed on the housing 100. The heat-conducting component 200 is used to directly exchange heat with the parts, quickly transferring the heat generated by the parts through direct contact and avoiding excessive local temperature of the parts. A heat exchange component 300 is connected to the heat-conducting component 200. The heat exchange component 300 is used to exchange heat with the heat-conducting component 200, further transferring and dissipating the heat absorbed by the heat-conducting component 200, and maintaining the heat dissipation capacity of the heat-conducting component 200. An inner shell 110 is nested inside the outer shell 100. A heat-insulating interlayer 120 is filled between the outer shell 100 and the inner shell 110. The heat-insulating interlayer 120 is made of aerogel material, which has extremely low thermal conductivity and can effectively block the high temperature generated by other components inside the equipment from being conducted through the outer shell 100 to the inner shell 110, thus preventing the heat dissipation core area from being affected by external temperature. A top cover 130 is installed on the top of the outer shell 100. A through pipe 131 is connected to the left and right sides of the top of the top cover 130. The through pipe 131 is made of ABS plastic, which combines lightweight and certain structural strength, and can guide airflow into and out of the equipment. A fan 132 is installed at the bottom of the top cover 130. The fan blades of the fan 132 are made of PP material, which has good temperature resistance and toughness. The fan 132 is shielded below the connection end of one of the through pipes 131 and the top cover 130. When the fan 132 is working, the outside air forms an airflow channel between the two through pipes 131, and the internal heat is carried out by the airflow, improving the heat dissipation efficiency.
[0017] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in this utility model, the heat-conducting component 200 includes a water pump 210 located outside the housing 100 and attached to the surface of the part, and a pair of liquid collection seats 220 sleeved at the bottom of the inner side of the housing 100. The pump body of the water pump 210 is made of aluminum alloy, which has good thermal conductivity and corrosion resistance, reducing the heat accumulation generated by the water pump 210 during operation. The liquid collection seats 220 are made of pure copper, which has high thermal conductivity and can quickly transfer the heat of the coolant transported by the water pipe 211 to the heat exchanger 221. The input and output ends of the water pump 210 are both connected to water pipes 211, which are made of silicone tubing. Silicone tubing has good flexibility and aging resistance, making it easy to... It adapts to different installation paths and prevents coolant leakage. The ends of the two water pipes 211 are connected to the two liquid collection seats 220 respectively. The bottom end of the water pump 210 is equipped with a base 212. Several flat heat spreader pipes 221 with hollow flow channels are connected between the two liquid collection seats 220. The heat spreader pipes 221 are made of oxygen-free copper. Oxygen-free copper has high purity and excellent thermal conductivity. The flat structure can increase the contact area with the bottom sleeve 320, which is conducive to heat transfer. The water pump 210, water pipes 211, liquid collection seats 220 and heat spreader pipes 221 form a closed water circulation loop. The coolant circulates in the loop and continuously absorbs the heat transferred by the parts to achieve continuous heat dissipation.
[0018] like Figure 5 As shown, specifically, the base 212 is made of pure copper. Pure copper can quickly transfer heat from the surface of the parts to the water pump 210 and subsequent cooling circuit. A flexible heat-conducting sheet 213 is attached to the bottom surface of the base 212. The heat-conducting sheet 213 is made of graphite heat-conducting pad. Graphite heat-conducting pad has good flexibility and thermal conductivity, which can adapt to the small bumps and depressions on the surface of the parts, fill the gap between the base 212 and the parts, and improve the heat transfer efficiency. The left and right sides of the outer shell 100 are provided with clearance holes 140. The clearance holes 140 penetrate the inner shell 110 and the heat insulation layer 120, providing a passage for the water pipe 211 to pass through, while avoiding direct contact between the water pipe 211 and the outer shell 100 and the inner shell 110, which would lead to heat conduction. The outer end of the liquid collecting seat 220 is provided with a threaded hole for installing the water pipe 211. The position of the threaded hole corresponds to the position of the clearance hole 140, ensuring that the water pipe 211 can be accurately connected to the liquid collecting seat 220, reducing the flow resistance of the coolant.
[0019] like Figure 2 and Figure 6As shown, the heat exchange assembly 300 further includes a top seat 310 and several bottom sleeves 320 located below the top seat 310. The top seat 310 is made of aluminum alloy, which is lightweight and has a certain heat dissipation capacity, dispersing the heat transferred by the heat pipe 330 to the cooling plate 312. The bottom sleeves 320 are made of pure copper, which has good thermal conductivity and can quickly transfer the heat from the heat spreader 221 to the heat pipe 330. Several heat pipes 330 are embedded between the bottom end of the top seat 310 and the bottom sleeves 320. The tube body of the heat pipe 330 is made of oxygen-free copper and filled with a sintered copper powder core, which can achieve working fluid circulation through capillary action. Its cooling principle is the same as that of the heat pipe of a computer CPU heat sink: the bottom of the heat pipe 330 near the bottom sleeve 320 is the evaporation end. When the heat transferred by the bottom sleeve 320 enters the evaporation end, the heat pipe 330... The liquid working fluid in the tube absorbs heat and evaporates into a gaseous state. Under the action of the pressure difference inside the tube, the gaseous working fluid flows towards the top condensation end near the heat-conducting seat 311. After reaching the condensation end, the gaseous working fluid comes into contact with the lower temperature heat-conducting seat 311, releases heat, and condenses back into a liquid state. The liquid working fluid then flows back to the evaporation end through the capillary force of the copper powder sintered core, forming a "evaporation-flow-condensation-reflux" cycle, which efficiently transfers heat. Several bottom sleeves 320 are respectively inserted between two adjacent heat-spreading tubes 221 to increase the contact area between the bottom sleeves 320 and the heat-spreading tubes 221 and improve the heat transfer efficiency. Several cooling chips 312 are attached to the top of the top seat 310. The substrate of the cooling chip 312 is made of ceramic material. Ceramic material has good insulation and excellent thermal conductivity, which can achieve separation of hot and cold ends when energized, providing additional cooling capacity for the top seat 310.
[0020] like Figure 2 and Figure 6As shown, the bottom end of the top seat 310 is integrally formed with several heat-conducting seats 311. The heat-conducting seats 311 are made of the same material as the top seat 310. The integral structure can reduce heat transfer loss. The number of heat-conducting seats 311 is equal to the number of bottom sleeve seats 320 and their positions correspond one-to-one. This ensures that the heat pipes 330 on each bottom sleeve seat 320 can be accurately connected to the heat-conducting seats 311, while providing a stable heat dissipation carrier for the condensation end of the heat pipes 330. The top of the heat pipes 330 is embedded in the side surface of the heat-conducting seats 311. The tight fit reduces the contact gap, improves the heat transfer efficiency, and helps the gaseous working fluid to release heat efficiently at the condensation end. The heat pipe 330 has a flat U-shaped tubular structure. This flat structure increases the contact area with the base 320 and the heat-conducting seat 311, enhancing the heat absorption at the evaporation end and the heat release at the condensation end. The U-shaped structure facilitates arrangement in a limited space, shortens the flow path of the gaseous working fluid, and improves circulation efficiency. The bottom of the heat pipe 330 is embedded in the side wall of the base 320, and the outer surface of the heat pipe 330 is flush with the side surface of the base 320, avoiding any protruding structure that could interfere with the installation of other components. Two heat pipes 330 are symmetrically installed on each base 320, evenly distributing the heat pipes across the base 320. The heat absorbed is zero, avoiding local heat accumulation that could lead to uneven load on the evaporator end of the heat pipe 330; a filler plate 222 is used between the bottom sleeve 320 and the side wall of the heat spreader 221. The filler plate 222 is made of graphite thermal conductive sheet, which can fill the gap between the bottom sleeve 320 and the heat spreader 221, and has good thermal conductivity to ensure that heat can be efficiently transferred to the evaporator end of the heat pipe 330; the gap between the bottom of the heat pipe 330 and the heat spreader 221 is filled by the filler plate 222, further reducing the heat transfer blind zone and ensuring that the evaporator end of the heat pipe 330 can continuously and stably absorb heat.
[0021] like Figure 2 and Figure 6 As shown, it is worth noting that a rectangular sleeve plate 313 is fitted and fixed on the outer periphery of the top seat 310. The sleeve plate 313 is made of ABS plastic and glass fiber composite material, which has both structural strength and heat insulation. The outer periphery of the sleeve plate 313 is in close contact with the inner wall of the inner shell 110. The close contact achieves the separation of the internal space of the inner shell 110 and avoids air flow between the upper and lower areas. The sleeve plate 313 separates the interior of the inner shell 110, so that the bottom seat 320, heat pipe 330 and liquid collection seat 220 located at the bottom are isolated inside the outer shell 100, reducing the interference of other hot air inside the equipment to this area and maintaining a stable heat absorption environment at the evaporation end of the heat pipe 330. The space above the sleeve plate 313 is connected to the outside through the pipe 131, which facilitates the fan 132 to drive the airflow and quickly remove the heat from the top seat 310 and the cooling plate 312, indirectly cooling the condenser end of the heat pipe 330 and improving its condensation efficiency.
[0022] It is worth noting that the fan 132, water pump 210 and cooling chip 312 involved in this utility model are all existing conventional technologies, and will not be described in detail in this utility model.
[0023] In this embodiment, the dual-engine liquid cooler integrating insulation and latent heat exchange principles operates as follows: First, the heat-conducting plate 213 on the bottom surface of the base 212 is attached to the surface of the part to be cooled. The heat generated by the part is transferred through the heat-conducting plate 213 to the pure copper base 212, and then from the base 212 to the water pump 210 and the connected water pipe 211. Then, the water pump 210 is started, and the coolant flows in a closed water circulation loop consisting of "water pump 210-water pipe 211-liquid collector 220-heat spreader 221". After absorbing heat in the heat spreader 221, the coolant transfers the heat to the bottom sleeve 320 through the filler plate 222. The bottom sleeve 320 then transfers the heat to the evaporation end of the heat pipe 330, triggering the "evaporation-flow" cycle of the working fluid inside the heat pipe 330. Next, the gaseous working fluid inside the heat pipe 330 flows to the top. At the condensing end, heat is transferred to the heat-conducting base 311 and the top base 310, then condenses into a liquid and flows back to the evaporating end. If the heat is too high and the sensible heat exchange efficiency is insufficient, the cooling plate 312 at the top of the top base 310 is activated. The cooling plate 312 further reduces the temperature of the top base 310 through active cooling, accelerating the heat release at the condensing end of the heat pipe 330. At the same time, the fan 132 at the bottom of the top cover 130 is activated. Outside air enters the upper space of the sleeve plate 313 through a pipe 131, flows through the cooling plate 312 and the top base 310, and carries heat out through another pipe 131. Finally, during the entire operation, the heat insulation layer 120 between the outer shell 100 and the inner sleeve 110 prevents the intrusion of high external temperatures, and the sleeve plate 313 isolates the upper and lower spaces to prevent hot air cross-flow, thus maintaining the circulation efficiency of the heat pipe 330 and the overall heat dissipation stability of the equipment.
