Description

Technical Field

[0001] This invention belongs to the field of adjustable temperature distribution plate technology, and more specifically, relates to a high-performance, visual, adjustable temperature distribution plate for energy storage and its usage method. Background Technology

[0002] With the rapid development of miniaturization and integration of electronic devices, the power and heat flux density of electronic devices are constantly increasing, leading to increasingly prominent heat dissipation problems. If the heat generated during operation is not dissipated in time, it will accumulate, causing localized temperature increases, a sharp decline in the performance of the electronic device, and even threatening its lifespan. To solve the heat dissipation problem of high-power electronic devices, high-performance heat dissipation is needed. Effective heat dissipation technology can ensure the stable operation of electronic devices and extend their lifespan. Currently, electronic devices primarily utilize two methods for heat dissipation: active cooling and passive cooling. Passive cooling mainly employs natural convection and radiation heat transfer, but its application is limited for high-power electronic devices. Active cooling, on the other hand, boasts advantages such as strong heat exchange capacity and wide applicability, making it the primary solution for high-power electronic heat dissipation. Existing active cooling methods include air cooling, liquid cooling, thermoelectric cooling, and phase change cooling. Because substances undergo a phase transition process that absorbs and amplifies latent heat at an isothermal temperature, phase change cooling offers excellent heat absorption, storage, and temperature equalization capabilities, as well as the advantage of not requiring external cooling or driving equipment. This makes phase change cooling technology a crucial technology for solving heat dissipation issues in integrated and miniaturized electronic devices. Especially for applications such as lasers and radar, which are characterized by short-term high heat generation with pulsed and periodic patterns and no strict requirements on recovery time, phase change cooling technology can utilize the latent heat of phase change to absorb the large amount of heat generated by electronic devices in a short period, achieving temperature equalization and heat dissipation. Then, it releases the heat over a sufficiently long period, returning the device to its initial state. However, with the miniaturization of electronic devices and the diversification of their operating modes, the requirements for the heat dissipation, temperature equalization, and adaptability of phase change heat dissipation technology are becoming increasingly stringent.

[0003] Chinese invention patent CN104241729A discloses a power battery heat dissipation device combining water cooling and composite phase change material, including a housing and a base plate disposed at the bottom of the housing. The base plate has an inlet channel and an outlet channel for accommodating cooling water along its two long sides. The upper surface of the base plate has channels communicating with the inlet and outlet channels along its two long sides. Plate-shaped microchannel heat exchangers are disposed at intervals along the length of the base plate. Microporous channels are disposed within the plate-shaped microchannel heat exchangers, with their two ends connected to the channels communicating with the inlet and outlet channels, respectively. The space enclosed by the plate-shaped microchannel heat exchangers, the base plate, and the housing is filled with composite phase change material. Furthermore, Chinese utility model CN207382775U discloses a water-cooled phase change heat dissipation device, consisting of water-cooled pipes and a phase change cavity, with the water-cooled pipes installed within the phase change cavity. A phase change chamber is a sealed cavity constructed based on the heat pipe principle. The surface of the phase change chamber is the evaporation end, and the surface of the water-cooled pipes is the condensation end. The water-cooled pipes are folded and meandered within the phase change chamber. Multiple porous flat tubes or multiple pipes are used within the phase change chamber to increase the area of ​​the condensation end and improve heat dissipation efficiency.

[0004] The above-mentioned patented technologies all use phase change materials to achieve effective heat dissipation of components, but there are still the following shortcomings: (1) The cavity-filled phase change material technology can effectively store heat by utilizing the large latent heat, but because organic phase change materials or organic phase change materials doped with high-performance thermally conductive nanoparticles are used as fillers, this technology has problems such as poor thermal conductivity, poor temperature uniformity, small latent heat per unit volume, large volume expansion during phase change, and poor cycle stability; (2) Since the phase change cavity uses a closed non-transparent metal skeleton, it is difficult to monitor the state of the phase change material in real time; (3) Since the structure of the phase change device is fixed, the same device cannot adapt to multiple power heat sources; (4) Since the phase change material can only store heat for a short time, the heat must be discharged through the coolant to achieve sustainable cycle. Traditional liquid cooling channels mostly adopt a serpentine or serpentine with fins structure. This structure has a small heat exchange area and relatively poor turbulence disturbance capability, resulting in limited convective heat transfer capability. Summary of the Invention

[0005] To address the aforementioned shortcomings or time-consuming improvements in existing technologies, this invention improves structural flexibility by making the phase change material filling space thickness adjustable. This allows for adaptation to different heating element power levels and personalized adjustments to the phase change material filling amount, broadening the application range of the vapor chamber. Furthermore, transparent viewing windows on both the front and rear sides enable real-time monitoring of the phase change material morphology change process, enhancing the controllability of the vapor chamber. Simultaneously, a water-cooled heat dissipation unit is located at the bottom of the adjustable-thickness phase change unit, with a turbulence-inducing section on its lower surface. This ensures the incoming flow is promptly processed into a turbulent state, effectively improving the heat exchange efficiency of the water-cooled heat dissipation. This invention effectively solves the technical problems of limited convective heat transfer capacity caused by the serpentine or serpentine-finned structures used in traditional liquid cooling channels, which result in small heat exchange area and relatively poor turbulence disturbance capability.

[0006] According to a first aspect of the present invention, a visualized high-performance energy storage variable temperature plate is provided, comprising:

[0007] The temperature plate frame used for supporting and positioning includes frame side plates, frame partition upper plate and frame partition lower plate.

[0008] The thickness-adjustable phase change unit is filled with phase change material and has an adjustable filling space size. Its side is connected to the side plate of the skeleton and placed on the upper surface of the upper plate of the skeleton partition.

[0009] A water-cooled heat dissipation unit for dissipating heat from the phase change material in the adjustable thickness phase change unit includes a heat exchanger channel sandwiched between the upper plate and the lower plate of the frame partition and having a turbulence excitation section inside, and an inlet and an outlet connected to the left and right sides of the heat exchanger channel for inputting and outputting coolant, respectively.

[0010] The front and rear transparent windows, which are fixedly connected to the frame side plates in the left and right directions and are set on the front and rear sides, are used to monitor the morphological changes of the internal phase change material. They are in the shape of transparent plates.

[0011] Furthermore, the thickness-adjustable phase change unit includes:

[0012] The upper cover plate, which serves as the sealing phase change material, has a phase change material injection hole on its surface for injecting the phase change material and sealing it with sealing bolts.

[0013] It is fixedly connected to the frame side plates on the left and right sides and is provided with a toothed positioning plate for adjusting the vertical height of the upper cover plate. Its inner surface has a plurality of grooves evenly arranged in the vertical direction for repeatedly disassembling and engaging with the upper cover plate for positioning.

[0014] An energy-storing adjustable phase change layer for filling phase change material is formed by a skeleton partition upper plate and an upper cover plate that are set at the bottom of the toothed positioning plate and fixedly connected to the left and right skeleton side plates.

[0015] Furthermore, the thickness-adjustable phase change unit includes:

[0016] As the upper cover of the energy storage adjustable phase change layer, it is detachably connected to the skeleton side plates on the left and right sides. The upper cover has a phase change material injection hole on its surface for injecting phase change material and sealing it with sealing bolts.

[0017] Multiple detachable and adjustable panels can be stacked on top of the frame partition;

[0018] An energy storage adjustable phase change layer for filling phase change materials is formed by the top removable adjustable plate and the top cover plate.

[0019] Furthermore, the turbulence-inducing part in the heat exchanger channel is an irregular tooth arranged in an array on the lower surface of the heat exchanger channel to disperse the incoming flow and create a turbulent state.

[0020] Furthermore, the front and rear transparent viewing windows are made of corrosion-resistant transparent acrylic sheets.

[0021] Furthermore, both the heat spreader frame and the water-cooled heat dissipation unit are made of metal materials.

[0022] According to a second aspect of the present invention, a method for using a visualized high-performance energy storage variable temperature plate is provided, comprising the following steps:

[0023] The required amount of phase change material is determined by calculating the heat generated during the operation of laser and radar electronic products.

[0024] Adjust the thickness of the adjustable phase change layer inside the adjustable phase change unit to correspond to the required amount of phase change material, fill the phase change material into the adjustable phase change layer, and fix the visualization transparent window to the heat spreader frame.

[0025] The heat load is fixed on the upper surface of the cover plate, and the fluid is introduced through the flow channel composed of the inlet and outlet and the heat exchanger water channel. After the heat exchange process, the phase change material will solidify. After the phase change material is completely solidified, the liquid supply is stopped.

[0026] The thermal load is activated, and the melting of the phase change material is observed through a transparent visualization window, thereby recording the morphological change process of the phase change material.

[0027] After the operation is stopped, fluid is introduced again to restore the phase change material to its initial transformed state.

[0028] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0029] 1. This invention discloses a high-performance, visualized, variable-temperature vapor chamber. By making the phase change material filling space adjustable in thickness, it effectively improves structural flexibility, thereby adapting to the heating power of different heating elements and enabling personalized adjustment of the phase change material filling amount, thus broadening the application range of the vapor chamber. Furthermore, visual transparent windows are provided on both the front and rear sides, allowing for real-time monitoring of the phase change material morphology change process and enhancing the controllability of the vapor chamber. Simultaneously, a water-cooled heat dissipation unit is provided at the bottom of the adjustable-thickness phase change unit, and a turbulence excitation section is provided on the lower surface of the water-cooled heat dissipation unit, ensuring that the incoming flow is promptly processed into a turbulent state, effectively improving the heat exchange efficiency of water cooling. This effectively solves the technical problems of limited convective heat transfer capacity caused by the serpentine or serpentine-finned structures used in traditional liquid cooling channels, which result in small heat exchange area and relatively poor turbulence disturbance capability.

[0030] 2. The present invention provides a visual high-performance energy storage variable temperature plate, which, by setting a vertical toothed positioning plate, forms a detachable structure with an adjustable upper cover height, greatly facilitating the operator's adaptation and adjustment of different heat dissipation power components. At the same time, the toothed structure and the upper cover plate are positioned to achieve a good sealing effect on the phase change material. In addition, another embodiment is proposed, which effectively adjusts the thickness of the phase change material filling cavity by fixing the upper cover plate and using the method of stacking the number of detachable adjustment plates 11 below the filling cavity. In use, firstly, according to the thickness requirement of the filling cavity, the corresponding number of detachable adjustment plates 11 are stacked on the upper surface of the lower plate of the skeleton partition, thereby realizing the adjustable thickness of the filling wall.

[0031] 3. The present invention provides a visual high-performance energy storage variable temperature plate. When water flows in from the inlet, it collides with the irregular teeth on the lower surface of the heat exchanger water channel 10, thereby causing turbulence and creating a turbulent state. The heat exchange efficiency between the fluid and the upper surface is correspondingly improved in the turbulent state, thus effectively enhancing the heat dissipation efficiency. Furthermore, by setting the water cooling heat dissipation to an intermittent working state, the power of the air cooling heat dissipation equipment is effectively reduced, thereby reducing the size of the equipment. This solves the technical problem that traditional heat dissipation methods achieve heat dissipation and temperature equalization by transferring heat from the evaporation end (heat generation end) to the condensation end (heat release end), which cannot temporarily store heat and requires simultaneous heat generation and dissipation, thus preventing the miniaturization of cooling equipment.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figures 1-4 As shown in the embodiment of the present invention, a visualized high-performance energy storage variable temperature plate includes:

[0040] The temperature plate frame 1, which serves to provide support and positioning, includes a frame side plate, a frame partition upper plate, and a frame partition lower plate.

[0041] The thickness-adjustable phase change unit is filled with phase change material and has an adjustable filling space size. Its side is connected to the side plate of the skeleton and placed on the upper surface of the upper plate of the skeleton partition.

[0042] A water-cooled heat dissipation unit for dissipating heat from the phase change material in the adjustable thickness phase change unit includes a heat exchanger channel 10 sandwiched between the upper plate and the lower plate of the skeleton partition and having a turbulence excitation section inside, and an inlet and an outlet connected to the left and right sides of the heat exchanger channel 10 for inputting and outputting coolant, respectively.

[0043] The front and rear transparent windows, which are fixedly connected to the frame side plates in the left and right directions and are set on the front and rear sides, are used to monitor the morphological changes of the internal phase change material. They are in the shape of transparent plates.

[0044] The phase change material can be selected from gallium-tin-indium liquid metal with an adjustable melting point in the room temperature range, high thermal conductivity, and high volumetric specific heat capacity.

[0045] In this embodiment of the invention, by setting the phase change material filling space to be of adjustable thickness, the structural flexibility is effectively improved, thereby adapting to the heating power of different heating elements and realizing personalized adjustment of the phase change material filling amount, thus broadening the application range of the vapor chamber. Furthermore, visual transparent windows are provided on both the front and rear sides, enabling real-time monitoring of the phase change material morphology change process and enhancing the controllability of the vapor chamber. Simultaneously, by setting a water-cooled heat dissipation unit at the bottom of the adjustable-thickness phase change unit, and providing a turbulence excitation section on the lower surface of the water-cooled heat dissipation unit, the incoming flow is promptly processed into a turbulent state, effectively improving the heat exchange efficiency of water cooling. This effectively solves the technical problems of limited convective heat transfer capacity caused by the serpentine or serpentine-finned structure adopted by traditional liquid cooling channels, which results in a small heat exchange area and relatively poor turbulence disturbance capability.

[0046] In operation, the required amount of phase change material (PCM) is first determined by calculating the heat generated by the laser and radar electronic products. Next, the thickness of the adjustable phase change layer inside the adjustable phase change unit is adjusted to correspond to the required amount of PCM, and the PCM is filled into the adjustable phase change layer. The visualization window is then fixed to the heat spreader frame. Next, the heat load is fixed to the upper surface of the top cover plate, and fluid is introduced through the inlet / outlet and heat exchanger channels. The PCM solidifies during the heat exchange process, and the fluid supply is stopped after observing complete solidification through the visualization window. Then, the heat load resumes operation, and the melting of the PCM is observed through the visualization window, thus recording the morphological changes of the PCM. After stopping operation, fluid is introduced again to restore the PCM to its initial state.

[0048] The upper cover plate 4, which serves as the upper cover sealing phase change material, has a phase change material injection hole on its surface for injecting phase change material and sealing it with sealing bolts 7.

Its inner surface is evenly arranged with a plurality of grooves for repeatedly disassembling and engaging with the upper cover plate 4 for positioning.

[0050] An energy-storing adjustable phase change layer 9, which is set at the bottom of the toothed positioning plate and fixedly connected to the left and right side plates of the skeleton, and is composed of the skeleton partition upper plate and the upper cover plate 4, for filling phase change material.

[0051] In this embodiment of the invention, by setting a vertical toothed positioning plate, a detachable structure with adjustable height of the upper cover plate is formed, which greatly facilitates the operator to adapt and adjust different heat dissipation power components. At the same time, by positioning the toothed structure with the upper cover plate, a good sealing effect on the phase change material can be achieved.

[0052] In use, first, the toothed positioning plate is vertically fixed to the inner surface of the frame side plates on both sides; then, according to the calculated thickness requirement, the groove position of the upper cover plate at the corresponding height to be installed on the toothed positioning plate is determined; then, the phase change material is injected into the thickness adjustable phase change unit through the phase change material injection hole, thereby realizing the effective adjustment of the thickness of the phase change material filling cavity space in the direction of the phase change material filling cavity.

[0054] The upper cover plate 4, which serves as the cover of the energy storage adjustable phase change layer 9, is detachably connected to the skeleton side plates on the left and right sides.

[0056] An energy storage adjustable phase change layer 9, consisting of the uppermost detachable adjustable plate 11 and the upper cover plate 4, is used to fill the phase change material.

[0057] In this embodiment of the invention, the thickness of the phase change material filling cavity is effectively adjusted by fixing the upper cover plate and using the method of stacking the number of detachable adjustable plates 11 below the filling cavity. In use, firstly, according to the thickness requirements of the filling cavity, the corresponding number of detachable adjustable plates 11 are stacked on the upper surface of the lower plate of the skeleton partition, thereby realizing the adjustable thickness of the filling wall.

[0059] Irregular teeth arranged in an array on the lower surface of the heat exchanger channel 10 to disperse the future flow and create turbulence.

[0060] In this embodiment of the invention, when the water flows in from the inlet, it collides with the irregular teeth on the lower surface of the heat exchanger channel 10, thereby causing turbulence and forming a turbulent state. The heat exchange efficiency between the fluid and the upper surface in the turbulent state will be improved accordingly, thereby effectively enhancing the heat dissipation efficiency.

[0061] In this embodiment of the invention, the front transparent window 5 and the rear transparent window 6 are made of corrosion-resistant transparent organic glass.
