Description

Technical Field

[0001] This utility model belongs to the field of absorption cooling technology, specifically relating to a desktop computer processor collaborative heat dissipation structure. Background Technology

[0002] As the computing performance of desktop computers continues to improve, the heat generated by various components is also constantly increasing.

[0003] To address this trend, while heatsink designs have continuously improved, their performance remains limited by space constraints, ambient temperature, and the physical properties of the components themselves. Especially under stringent space limitations, the volume occupied by traditional air-cooled or water-cooled systems can easily lead to boundary effects, resulting in insufficient heat dissipation performance from the heatsink components. Therefore, this invention proposes a collaborative heat dissipation structure for desktop computer processors. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a desktop computer processor collaborative heat dissipation structure, including a chassis and a motherboard installed inside the chassis. The motherboard has a CPU located at the corresponding processor position. An absorption cooler is detachably connected inside the chassis. A commercially available heat dissipation module corresponding to the CPU can also be detachably installed on the motherboard. The commercially available heat dissipation module and the absorption cooler work together to dissipate heat from the CPU. The absorption cooler includes a first 3D heat pipe and a second 3D heat pipe, both of which can be detachably installed on the motherboard and one end of which is attached to the CPU. The first 3D heat pipe is fixedly connected to the heat exchange plate, and the second 3D heat pipe is fixedly connected to the ammonia water storage tank. Secondly, the absorption chiller also includes a condenser tube installed on the top of the ammonia water storage tank. The heat exchange plate runs through the middle of the condenser tube. A fan is detachably installed on one side of the heat exchange plate, and the other side is detachably connected to the heat sink. Meanwhile, the contact area between the condenser tube and the heat exchange plate has a serpentine bend structure to improve heat exchange efficiency. The input end of the condenser tube is connected to the air outlet of the ammonia water storage tank, and the output end of the condenser tube is connected to the air inlet of the ammonia water storage tank. Furthermore, a connecting plate is fixedly installed at the connection end between the first 3D heat pipe and the second 3D heat pipe and the CPU, and the first 3D heat pipe and the second 3D heat pipe can be detachably installed on the motherboard through the connecting plate. Furthermore, the fan is an adjustable-speed DC cooling fan, which is electrically connected to the motherboard via wires. The motherboard is equipped with a speed control module adapted to the fan, and the fan's airflow direction is towards the heat sink. The front side wall of the chassis is equipped with a USB interface module, which is electrically connected to the USB interface slot on the motherboard via a data cable. Secondly, a power switch is also embedded in the front side wall of the chassis. The power switch is electrically connected to the power control interface on the motherboard through a wire. The outer side of the power switch is provided with an annular anti-accidental touch flange, which is integrally formed with the front side wall of the chassis. Meanwhile, the internal components of the chassis can be detachably installed, including the graphics card module, memory module, power supply module, and hard drive module.

[0005] Compared with the prior art, this utility model has the following advantages: This invention conducts a portion of the processor's heat to an absorption cooler via a first 3D heat pipe and a second 3D heat pipe for pre-heat dissipation; then, excess heat is dissipated via a commercially available heat dissipation module, allowing the processor to use both an absorption cooler and a commercially available heat dissipation module for heat dissipation simultaneously, resulting in high heat dissipation efficiency and meeting the heat dissipation requirements of high-power CPUs.

[0006] 2. This utility model has a high energy utilization rate. It converts the CPU waste heat into the driving energy of the absorption refrigeration cycle through the second 3D heat pipe, eliminating the need to provide an additional heating power supply for the cooler, reducing the overall power consumption of the computer, and achieving a waste heat utilization rate of over 30%.

[0009] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0010] like Figure 1-4 The present invention discloses a desktop computer processor co-heating structure, including a chassis 1 and a motherboard 2 installed inside the chassis 1. A CPU 15 is provided on the motherboard 2 corresponding to the processor position. The characteristic is that an absorption cooler is detachably connected inside the chassis 1, and a commercially available heat dissipation module 3 corresponding to the CPU 15 can also be detachably installed on the motherboard 2. The commercially available heat dissipation module 3 and the absorption cooler work together to dissipate heat from the CPU 15. 1. Component installation Case and motherboard installation: Select standard ATX case 1. The motherboard 2 is ATX in size and is fixed to the bottom of case 1 with four copper pillars and bolts. The CPU socket of motherboard 2 is located in the middle of the motherboard. Install Intel i7-13700K CPU15, power 125W, and apply 0.5mm thick thermal paste to the surface of the CPU.

[0011] Installation of commercially available heatsink module: Select a commercially available heatsink module 3 from a certain brand of air cooler and fix it to the CPU bracket of the motherboard 2 with the fastener. The bottom of the heatsink should be in contact with the thermal paste on the surface of the CPU 15 to ensure heat conduction.

[0012] Absorption cooler installation: The first 3D heat pipe 4 and the second 3D heat pipe 4 are fixed by a connecting plate 16. One side of the connecting plate 16 is connected to the pre-drilled screw holes of the motherboard 2 by two M3 bolts, and the other side is welded to the 3D heat pipe. A thermally conductive silicone pad is glued to the end of the 3D heat pipe that contacts the CPU 15 to ensure tight contact. The other end of the first 3D heat pipe 4 is welded to the center of the heat exchange plate 8. A 120mm DC fan 7 (model ADDAAD0812HB-A73GL, speed 1000-2000RPM) is installed on the left side of the heat exchange plate 8 by two self-tapping screws, and an aluminum heat sink 9 is attached to the right side by thermally conductive adhesive.

[0013] The ammonia water storage tank 6 has a volume of 60mL and is filled with 28% ammonia water (the filling volume is 70% of the storage tank volume). The other end of the second 3D heat pipe 5 is welded to the bottom of the storage tank. The storage tank is fixed to the inner wall of the chassis 1 by two plastic cable ties, with a distance of not less than 15mm from the main board 2 to avoid short circuits. The serpentine bend in the middle of the condenser pipe 12 passes through the reserved hole of the heat exchange plate 8. The condenser pipe inlet 10 is sealed to the air outlet at the top of the storage tank by a nitrile rubber sealing ring. The condenser outlet 11 is similarly connected to the air inlet of the storage tank, forming a closed loop.

[0014] Other module installations: The graphics card module is plugged into the PCIe 4.0 slot of motherboard 2, the memory module is plugged into the DIMM slot of motherboard 2, the power supply module is fixed to the bottom of chassis 1, and the hard drive module is installed on the hard drive bracket of chassis 1; the USB interface module 14 is embedded in the front side wall of chassis 1 and connected to the USB 3.2 slot of motherboard 2 via a data cable; the power switch 13 is embedded on the left side of the USB interface module 14 and connected to the power control interface of motherboard 2 via a wire.

[0015] 2. Work Process Heat conduction stage: The CPU15 generates heat during operation, which is transferred to the first 3D heat pipe 4 and the second 3D heat pipe 5 through thermal grease and thermal pad; the thermal working fluid in the first 3D heat pipe 4 is vaporized by heat and quickly transfers the heat to the heat exchange plate 8; the second 3D heat pipe 5 similarly transfers the heat to the ammonia water storage tank 6.

[0016] Heat exchange and cooling cycle stage: After the heat exchange plate 8 is heated, the fan 7 starts (initially at 1000 RPM; when the CPU temperature exceeds 70℃, the speed control module of the motherboard 2 increases the speed to 2000 RPM). The fan airflow blows towards the heatsink 9, and the heat is diffused through the fins of the heatsink and discharged through the chassis ventilation holes. After receiving heat, the ammonia water tank 6 is heated to 60-70℃, producing ammonia vapor. The ammonia vapor enters the condenser pipe 12 through the condenser pipe inlet 10. The serpentine section of the condenser pipe 12 contacts the heat exchange plate 8 and is cooled to 30-35℃, where the ammonia vapor condenses into liquid ammonia. The liquid ammonia flows back to the ammonia water tank 6 through the condenser outlet 11, completing one cooling cycle and continuously reducing the temperature around the CPU. Collaborative cooling stage: The fans of the commercially available cooling module 3 operate simultaneously, conducting the remaining heat on the CPU surface to the inside of the chassis. Together with the heat discharged by the absorption cooler, it is discharged through the chassis ventilation holes, achieving dual cooling of the CPU.
