Abstract
Description
Technical Field
[0001] This utility model relates to the field of phase change radiator technology, and in particular to a high-efficiency radiator using a phase change heat-concentrating plate. Background Technology
[0002] A phase change heat sink is a device that uses the heat absorption and release phenomena during the phase change process of a substance to achieve heat dissipation. During the phase change process, a large amount of heat can be absorbed or released from the ambient temperature, thereby achieving the purpose of heat dissipation. A phase change heat sink is mainly composed of a phase change material, a packaging container, and a heat sink. It has the advantages of high heat dissipation efficiency, small size, and light weight, and is widely used in electronic equipment, new energy vehicles, aviation, aerospace and other fields.
[0003] In existing technologies, during long-term operation of phase change heat sinks, the thermal grease placed between the phase change components and the heat source may gradually dry out due to high-temperature aging, volatilization, or pumping effect, resulting in increased interfacial thermal resistance and a significant decrease in heat transfer efficiency. Since most current methods rely on fixed maintenance cycles or experience to determine when to replace the grease, there is a lack of real-time performance monitoring methods, which can easily lead to untimely maintenance or waste of resources. Utility Model Content
[0004] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this utility model provides a high-efficiency radiator constructed using a phase change heat-concentrating plate. This solves the problem that in the prior art, during long-term operation, the thermal grease placed between the phase change component and the heat source may gradually dry out due to high-temperature aging, volatilization, or pumping effect, leading to increased interfacial thermal resistance and a significant decrease in heat transfer efficiency. Currently, most grease replacement timing relies on fixed maintenance cycles or experience-based judgment, lacking real-time performance monitoring methods, which easily results in untimely maintenance or resource waste.
[0005] (II) Technical Solution To achieve the above objectives, the main technical solution adopted by this utility model is as follows: A high-efficiency radiator using a phase change heat-concentrating plate includes a radiator body, a lamp installed under the radiator body, heat dissipation fins fixedly connected to the outside of the radiator body, a disassembly device penetrating through the radiator body, and a monitoring device fixedly connected to the disassembly device. The disassembly device includes a mounting post that penetrates the heat sink body and forms a sliding connection with the heat sink body. A handle is fixedly connected to the mounting post, and a phase change heat-concentrating plate body is fixedly connected to the bottom of the mounting post. The phase change heat-concentrating plate body is attached to the chip inside the lamp.
[0006] The disassembly device also includes a housing, which is fixedly connected to the radiator body. The mounting post is disposed through the housing. The housing has a mounting groove and a sliding groove. A slider is fixedly connected to the outside of the mounting post.
[0007] The slider is disposed in the slide groove, and the mounting groove is connected to the slide groove.
[0008] A circular hole is provided through the housing, and a sliding connection is formed between the mounting post and the circular hole.
[0009] The height of the groove is slightly greater than the height of the slider, and the two form a sliding connection.
[0010] The monitoring device includes a temperature sensor, which is fixedly connected to the housing, and the detection rod extends into the heat sink fins. A connecting plate is fixedly connected to the temperature sensor, and a mounting base is fixedly connected to the connecting plate. A miniature alarm is fixedly connected to the mounting base.
[0011] The temperature sensor has a detection rod fixedly connected to its detection end, and the detection rod is L-shaped.
[0012] (III) Beneficial Effects The beneficial effects of this utility model are as follows: When it is necessary to replace the thermal grease, the operator can rotate the handle counterclockwise to make the handle drive the mounting column to rotate synchronously. The mounting column further drives the slider to rotate along the slide groove. When the slider rotates to the other end of the slide groove, the operator can pull the handle to make the mounting column and the phase change thermal plate body move synchronously until the phase change thermal plate body is completely separated from the heat sink body. At this time, the thermal grease can be reapplied to the surface of the phase change thermal plate body. After the thermal grease is applied, the mounting column and the phase change thermal plate body are reset, and the slider slides back into the mounting groove. Then, the operator rotates the handle clockwise to make the slider slide to the initial position of the slide groove, thus completing the addition of thermal grease and component reset operation. During the operation of the equipment, the detection rod is used to monitor the ventilation temperature at the heat sink fins in real time. When the detected temperature is lower than the preset threshold, the built-in controller automatically triggers the micro alarm. The alarm emits an audible and visual signal to remind the operator to replace the thermal grease in time, ensuring the heat transfer efficiency of the heat sink and the stability of the system operation.

[0015] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] Please refer to Figures 1 to 4 As shown, this utility model provides a high-efficiency radiator using a phase change heat-concentrating plate, which includes a radiator body 1, a lamp 3 installed under the radiator body 1, heat dissipation fins 2 fixedly connected to the outside of the radiator body 1, a disassembly device 4 penetrating inside the radiator body 1, and a monitoring device 5 fixedly connected to the disassembly device 4. The disassembly device 4 includes a mounting post 44, which is installed through the heat sink body 1. The mounting post 44 and the heat sink body 1 are slidably connected. A handle 45 is fixedly connected to the mounting post 44. A phase change heat-concentrating plate body 6 is fixedly connected to the bottom of the mounting post 44. The phase change heat-concentrating plate body 6 is attached to the chip inside the lamp 3. In actual implementation, when it is necessary to replace the silicone grease, the operator can rotate the handle 45 counterclockwise, so that the handle 45 drives the mounting post 44 to rotate synchronously. The mounting post 44 further drives the slider 46 to rotate along the slide groove 43. When the slider 46 rotates to the other end of the slide groove 43, the operator can pull the handle 45 to move the mounting post 44 and the phase change heat plate body 6 synchronously until the phase change heat plate body 6 is completely separated from the heat sink body 1. At this time, the silicone grease can be reapplied to the surface of the phase change heat plate body 6. After the silicone grease is applied, the mounting post 44 and the phase change heat plate body 6 are reset, so that the slider 46 slides back into the mounting groove 42. Then, the handle 45 is rotated clockwise to make the slider 46 slide to the initial position of the slide groove 43, thus completing the silicone grease addition and component reset operation.
[0017] Optionally, the disassembly device 4 also includes a housing 41, which is fixedly connected to the radiator body 1. A mounting post 44 is disposed through the housing 41, and the housing 41 has a mounting groove 42 and a sliding groove 43. A slider 46 is fixedly connected to the outside of the mounting post 44. In actual implementation, the housing 41, fixedly connected to the radiator body 1, serves as a unified support platform for the slider 46, sliding groove 43, mounting post 44, and other structures, providing a stable installation foundation and ensuring accurate relative positions between components. This prevents component misalignment or loosening from affecting the reliability of the disassembly and assembly operations.
[0018] Optionally, the slider 46 is disposed within the slide groove 43, and the mounting groove 42 is connected to the slide groove 43. In actual implementation, the connection between the mounting groove 42 and the slide groove 43 facilitates a smooth transition of the slider 46 to the mounting groove 42 area after completing its rotation or sliding stroke. This connection improves operational continuity, making the assembly and disassembly of the mounting column 44 and the phase change heat-concentrating plate body 6 smoother, avoiding forced pulling that could cause component wear or misassembly, and contributing to the stability of precise reset and repeated use.
[0019] Optionally, a circular hole is provided through the housing 41, and a sliding connection is formed between the mounting post 44 and the circular hole. In actual implementation, the sliding connection between the mounting post 44 and the circular hole in the housing 41 allows the mounting post 44 to have controllable axial and rotational freedom of movement during loading and unloading. This fit structure helps to maintain the positional constraint of the mounting post 44 during sliding, prevents lateral swaying, reduces wear, and extends the service life of the mechanical connection components.
[0020] Optionally, the height of the groove 43 is slightly greater than the height of the slider 46, and the two form a sliding connection. In actual implementation, the slider 46 is set in the groove 43, and the height of the groove 43 is slightly greater than the height of the slider 46, forming a sliding connection. This structure ensures that the slider 46 moves smoothly along a predetermined trajectory within the groove 43, while avoiding jamming due to excessive tightness or shaking due to excessive clearance, thus improving the reliability and stability of the structure. It is particularly suitable for scenarios that require frequent loading and unloading but have certain requirements for guiding accuracy.
[0021] Optionally, the monitoring device 5 includes a temperature sensor 51, which is fixedly connected to the housing 41. A detection rod 52 extends into the heat sink 2. A connecting plate 53 is fixedly connected to the temperature sensor 51, and a mounting base 54 is fixedly connected to the connecting plate 53. A miniature alarm 55 is fixedly connected to the mounting base 54. In actual implementation, during equipment operation, the detection rod 52 is used to monitor the ventilation temperature at the heat sink 2 in real time. When the detected temperature is lower than a preset threshold, the built-in controller automatically triggers the miniature alarm 55, which emits an audible and visual signal to prompt the operator to replace the thermal grease in a timely manner, ensuring the heat transfer efficiency of the heat sink and the stability of the system operation.
[0022] Optionally, a detection rod 52 is fixedly connected to the detection end of the temperature sensor 51, and the detection rod 52 is L-shaped. In actual implementation, the L-shaped detection rod 52 structure allows the sensing end to extend and bypass the structural limitations of the housing 41, and is accurately positioned at the heat sink fins 2, improving the representativeness and response speed of the temperature measurement.
[0023] The above describes the basic principles, main features, and advantages of this utility model. All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections adopt conventional connection methods in the prior art, which will not be detailed here.
