Technical Field
[0001] This utility model relates to the field of radiator technology, and in particular to a radiator and a medical treatment device. Background Technology
[0002] In the prior art, some medical treatment devices usually generate heat when working. A circulating water pump is used to flow water through the heat-generating components of the medical treatment device, while the water in the circulating water pump is cooled to dissipate heat, so as to maintain continuous cooling of the heat-generating components.
[0003] Currently, the common practice is to concentrate the circulated and cooled water in a tank, and then use refrigeration or cooling equipment outside the tank to dissipate heat or lower its temperature. However, this method of dissipating heat or cooling the tank is slow and has low heat transfer efficiency. Utility Model Content
[0004] The main purpose of this invention is to propose a radiator and a medical treatment device that aims to improve heat transfer efficiency and thus enhance heat dissipation.
[0005] To achieve the above objectives, this utility model proposes a radiator, the radiator comprising:
[0006] A liquid storage tube, wherein a heat source liquid is circulated within the liquid storage tube;
[0007] The heat sink fin assembly, wherein the liquid storage tube passes through the heat sink fin assembly; and
[0008] A heat pipe has an evaporation end and a condensation end at its two ends, respectively. The evaporation end extends into the liquid storage pipe, and the condensation end is connected to the heat dissipation fin assembly.
[0009] In one embodiment, the number of heat pipes is multiple.
[0010] In one embodiment, the evaporation ends of the plurality of heat pipes are arranged at intervals in the liquid storage tube.

Each heat dissipation fin is connected to the two second heat exchange plates at both ends. Each second heat exchange plate is provided with a central mounting hole. The liquid storage pipe and the first heat exchange plate are both inserted through the central mounting hole.
[0015] In one embodiment, the radiator further includes a mounting bracket and a fan assembly, the mounting bracket being connected to one side of the heat dissipation fin assembly, and the fan assembly being mounted on the side of the mounting bracket facing away from the heat dissipation fin assembly.

[0034] In existing technologies, radiators typically use metal tubes as heat conduction components with metal fins welded onto them. Because heat is concentrated around the metal tubes and difficult to dissipate, heat transfer efficiency is low. This heat accumulation problem is particularly pronounced when applied to high-power equipment, directly impacting the stability of equipment operation.
[0035] To address these issues, traditional solutions attempt to improve heat dissipation by increasing the length of the metal tube or the density of the fins. However, these methods are limited by the thermal conductivity of the materials and the structural design, failing to effectively overcome the thermal resistance bottleneck. By observing the principle of phase change heat transfer, it was discovered that the liquid working fluid can rapidly transfer heat through an evaporation-condensation cycle within a closed pipeline. Therefore, a proposal is made to combine a phase change heat transfer component with a liquid pipeline, optimizing the heat conduction path while maintaining a compact structure.
[0036] Therefore, this utility model proposes a radiator.
[0037] The aforementioned radiator is used within a medical treatment device. This device contains an energy generator that emits energy to treat the patient; this energy can be one or more types, such as light energy, ultrasound energy, electrical stimulation, or radio frequency energy. The energy generator generates heat during operation and requires cooling via a water pump and pipes. The water pipes are positioned close to or adjacent to the energy generator. The pump delivers cold or room-temperature water to these pipes to cool the energy generator. The water becomes hotter after cooling, transforming into a heat-generating liquid. This heat-generating liquid then flows into a storage pipe, where it is cooled by the radiator before re-flowing into the water pipes to cool the energy generator.
[0038] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4In one embodiment of the present invention, the radiator includes a liquid storage pipe 10, a heat dissipation fin assembly 20, and a heat pipe 30. The liquid storage pipe 10 is used to circulate heat source liquid. The liquid storage pipe 10 is inserted into the heat dissipation fin assembly 20. The two ends of the heat pipe 30 are an evaporation end 30a and a condensation end 30b, respectively. The evaporation end 30a enters the liquid storage pipe 10, and the condensation end 30b is connected to the heat dissipation fin assembly 20.
[0039] The liquid storage pipe 10 is a sealed pipe that contains the heat source liquid, which can be made of copper alloy material. It is used to directly contact the high-temperature liquid and conduct heat. The heat dissipation fin assembly 20 is a heat dissipation structure composed of multiple metal fins, which can be made of aluminum fin array. It accelerates air convection by increasing the surface area. The heat pipe 30 is a vacuum-sealed pipe filled with a phase change working fluid, which can be made of copper capillary structure. It achieves rapid heat conduction through the phase change of the working fluid. The evaporation end 30a is the part of the heat pipe 30 that contacts the heat source. It can be made by setting a capillary wick structure on the inner surface of the pipe wall to promote the vaporization of the working fluid by absorbing heat. The condensation end 30b is the part of the heat pipe 30 that connects to the heat dissipation structure. It can be made by increasing the pipe diameter or increasing the heat dissipation area to accelerate the liquefaction of the working fluid and release heat.
[0040] Specifically, when the heat source liquid flows through the storage pipe 10, the heat is directly transferred to the evaporation end 30a of the heat pipe 30. The working fluid inside the evaporation end 30a vaporizes upon heating, forming steam. Under pressure difference, the steam rapidly flows to the condensation end 30b. The condensation end 30b exchanges heat with the heat dissipation fin assembly 20. After releasing heat, the steam re-liquefies, and the liquid working fluid returns to the evaporation end 30a through capillary action, completing the cycle. The direct connection between the heat source liquid in the storage pipe 10 and the heat pipe 30 avoids the contact thermal resistance of traditional welded structures. The phase change process of the working fluid inside the heat pipe 30 enables rapid heat transfer, while the heat dissipation fin assembly 20 enhances the heat dissipation area through a multi-layer structure.
[0041] Compared with existing technologies, traditional radiators rely on the welded contact between metal tubes and fins for heat transfer, and heat needs to be transferred through multiple interfaces, resulting in the accumulation of thermal resistance.
[0042] This invention constructs a closed-loop phase change heat transfer channel by directly inserting a heat pipe 30 into the liquid storage pipe 10 to contact the heat source liquid and connect it to the heat dissipation structure. This eliminates the thermal resistance loss at the intermediate contact surface. The working fluid circulation inside the heat pipe 30 enables active heat transport, overcoming the limitations of passive heat conduction in traditional structures. Furthermore, the phase change heat transfer mechanism of the heat pipe 30 significantly improves the heat conduction speed. The multi-layer structure of the heat dissipation fins effectively improves heat dissipation efficiency and avoids local heat accumulation around the pipe. This structure completes rapid heat transfer and diffusion within a limited space, solving the technical defect of low heat transfer efficiency in traditional radiators and thus improving the heat dissipation effect.
[0043] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 There are multiple heat pipes 30.
[0044] In this embodiment, multiple heat pipes 30 refer to two or more independent heat conduction elements, which can be made of copper, aluminum, or their alloys, and are arranged at intervals within the liquid storage pipe 10. Multiple heat pipes 30 form parallel heat transfer paths between the liquid storage pipe 10 and the heat dissipation fin assembly 20. By increasing the heat conduction contact area and dispersing the heat flux density, the heat transfer efficiency of a single heat pipe 30 is prevented from decreasing due to excessive local heat load, thus improving heat dissipation efficiency.
[0045] Specifically, the evaporation ends 30a of multiple heat pipes 30 extend into the liquid storage tube 10, and the condensation ends 30b are connected to the heat dissipation fin assembly 20. Each heat pipe 30 independently absorbs heat from the heat source liquid in the liquid storage tube 10 and transfers the heat to the heat dissipation fin assembly 20 through its own phase change heat transfer mechanism. Due to the increased number of heat pipes 30, the density of heat conduction channels per unit area on the surface of the liquid storage tube 10 is increased, and heat can be absorbed and distributed more evenly to the heat dissipation area. At the same time, the distribution of multiple heat pipes 30 can be adjusted according to the heat distribution characteristics of the liquid storage tube 10, for example, arranging more densely packed heat pipes 30 in high-temperature areas to optimize heat flow distribution.
[0046] Compared to existing technologies, traditional radiators rely on a single heat pipe 30 structure, resulting in heat concentration in the localized area where the heat pipe 30 contacts the liquid storage pipe 10, and the heat dissipation fin assembly 20 cannot fully absorb the diffused heat. In contrast, this solution uses a parallel layout of multiple heat pipes 30, which not only increases the total cross-sectional area of the heat conduction path but also reduces the heat transfer load of a single heat pipe 30 through distributed heat transfer, thereby reducing the decrease in heat transfer efficiency caused by localized overheating.
[0047] Through the above technical solution, this application can significantly improve the heat absorption rate of the heat source liquid in the storage pipe 10, avoid the heat transfer bottleneck caused by overload of the heat pipe 30, and at the same time, the heat is quickly dispersed to the heat dissipation fin assembly 20 through the synergistic effect of multiple heat pipes 30, eliminating the problem of reduced heat dissipation efficiency caused by heat accumulation in the traditional structure. In addition, the layout of multiple heat pipes 30 can be flexibly configured according to actual heat dissipation needs, enhancing the system's adaptability to heat load fluctuations.
[0048] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The evaporation ends 30a of multiple heat pipes 30 are arranged at intervals in the liquid storage pipe 10.
[0049] In this embodiment, the spaced arrangement around the liquid storage tube 10 refers to the evaporation ends 30a of the heat pipes 30 being arranged around the liquid storage tube 10 at a certain interval. Specifically, this can be achieved using a ring array or a matrix array. This arrangement allows the heat pipes 30 to form circumferential contact with the liquid storage tube 10, increasing the heat conduction area and preventing excessive local heat concentration. The spaced arrangement means that the evaporation ends 30a of two adjacent heat pipes 30 maintain a preset distance. Specifically, this can be achieved through equal or non-equal spacing. This design can prevent heat conduction paths from crossing and interfering due to excessively close distances between the heat pipes 30, ensuring that each heat pipe 30 operates independently.
[0050] In some embodiments, the liquid storage tube 10 is cylindrical, and multiple evaporation ends 30a are arranged in a ring around the center of the liquid storage tube 10. Specifically, after the evaporation ends 30a of the heat pipes 30 are arranged around the liquid storage tube 10, when the heat source liquid flows through the liquid storage tube 10, its heat is simultaneously absorbed by the multiple evaporation ends 30a distributed along the circumferential direction. Since each evaporation end 30a forms a uniformly covered contact point around the liquid storage tube 10, heat diffuses synchronously in the radial and circumferential directions, breaking the unidirectional heat flow limitation formed by the traditional linear arrangement. The spaced arrangement allows each heat pipe 30 evaporation end 30a to form an independent heat exchange area on the surface of the liquid storage tube 10, avoiding the overlap of the heat absorption capacity of the phase change material due to the small spacing between adjacent heat pipes 30, thereby optimizing the overall heat flow distribution.
[0051] In some other embodiments, the liquid storage tube 10 is prismatic, and multiple evaporation ends 30a are arranged in a rectangular array inside the liquid storage tube 10.
[0052] Compared to existing technologies, traditional radiators typically have heat pipes 30 arranged in a straight line along a single direction, resulting in only a portion of the surface of the liquid storage tube 10 contacting the heat pipes 30, leading to uneven heat dissipation. This solution addresses this by circumferentially arranging the heat pipes 30 to cover the entire area within the liquid storage tube 10. As the heat source liquid flows through the liquid storage tube 10, heat is absorbed simultaneously from all directions, resolving the heat accumulation problem caused by insufficient contact area in traditional structures. The spaced arrangement further eliminates the reduced heat transfer efficiency caused by densely arranged heat pipes 30. Thus, this application solves the problem of low heat transfer efficiency in traditional radiators due to heat concentration in a single area. With multiple heat pipes 30 evaporation ends 30a circumferentially distributed within the liquid storage tube 10, they can simultaneously absorb heat carried by the heat source liquid from multiple directions, significantly increasing the heat exchange contact area. The spaced arrangement ensures a reasonable distance between each heat pipe 30, avoiding interference from intersecting heat conduction paths, allowing each heat pipe 30 evaporation end 30a to operate independently and efficiently, achieving uniform heat diffusion and stable conduction.
[0053] Reference Figure 3 and Figure 8In one embodiment, the liquid storage pipe 10 has a cross-section that is smaller at both ends and larger in the middle. The smaller ends are for liquid inlet and outlet, while the larger middle section is for liquid storage. Specifically, the liquid storage pipe 10 includes an inlet section 102, a storage section 101, and an outlet section 103, all of which are cylindrical. The cross-sectional area of the storage section is larger than that of the outlet and inlet sections. When the evaporation end 30a extends into the liquid storage pipe 10, it enters from the top of the storage section 101, not from the inlet section 102 or the outlet section 103. This allows the storage section 102 to store as much liquid as possible, while the multiple heat pipes 30 installed inside it can have more contact with the heat source liquid, increasing heat dissipation efficiency.
[0054] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The distances between the multiple condenser ends 30b and the liquid storage tube 10 are all different.
[0055] In this embodiment, the different spacing between the condenser end 30b and the liquid storage tube 10 refers to the difference in distance between the two ends of each heat pipe 30. This can be achieved by using heat pipes of different lengths with different bending methods, such as adjusting the bending angle or extension path of the heat pipes 30 to create different spacing. This design allows each heat pipe 30 to form a differentiated heat conduction path during heat transfer, avoiding localized heat concentration caused by equidistant arrangement. Specifically, after the heat pipe 30 absorbs heat from the heat source liquid in the liquid storage tube 10 through the evaporator end 30a, the different spacing results in different path lengths for heat conduction to the heat dissipation fin assembly 20, causing heat to be gradually released in different areas of the heat dissipation fin assembly 20.
[0056] Specifically, when the heat source liquid flows within the storage pipe 10, heat is transferred to the condensation end 30b through the evaporation end 30a of multiple heat pipes 30. Because the condensation end 30b of each heat pipe 30 is spaced differently from the storage pipe 10, the heat conduction velocity within the heat pipes 30 forms a gradient distribution with the contact position of the heat dissipation fin assembly 20. Heat pipes with larger spacing transfer heat to the far end region of the heat dissipation fin assembly 20, while those with smaller spacing transfer heat to the near end region. This gradient distribution allows for a wider heat diffusion range within the heat dissipation fin assembly 20, preventing overheating in a single area due to the dense arrangement of heat pipes 30. Simultaneously, the different spacing of the heat pipes 30 can adapt to temperature variations of the heat source liquid along the length of the storage pipe 10. For example, areas with higher temperatures near the heat source inlet use smaller-spacing heat pipes 30 for rapid heat dissipation, while areas with lower temperatures use larger-spacing heat pipes 30 to extend the heat dissipation path.
[0057] According to the heat dissipation principle, the condensation end 30b, which is further away from the liquid storage pipe 10, is more densely packed, so that heat can be more widely diffused to the far end area of the heat dissipation fin assembly 20, avoiding excessive heat concentration in the area near the liquid storage pipe 10, thereby improving the heat dissipation efficiency of the entire heat dissipation fin assembly 20, preventing local overheating, and ensuring the stability and reliability of the heat dissipation device during operation.
[0058] The condenser end 30b closer to the liquid storage pipe 10 is more dispersed. In the high-temperature area near the heat source inlet, due to the fewer condenser ends, heat can be transferred to the near-end area of the heat dissipation fin assembly 20 more quickly and dissipated, effectively reducing the temperature of the heat source liquid in the liquid storage pipe 10. Conversely, the condenser end 30b further away from the liquid storage pipe 10 is more densely packed, which can better adapt to the heat dissipation needs of the lower-temperature area, extend the heat dissipation path, and allow heat to be released more fully in the far-end area of the heat dissipation fin assembly 20, further improving the overall heat dissipation effect.
[0059] This application, through a differentiated spacing design, forces heat to be released gradually at different locations on the heat dissipation fin assembly 20, thereby breaking the heat dissipation limitations of traditional structures and achieving a more uniform heat distribution. This solves the problem of uneven heat distribution caused by the equidistant distance between the evaporation end 30a and the condensation end 30b of the heat pipes 30, expanding the heat diffusion range of the heat dissipation fin assembly 20, avoiding localized overheating, and adapting to temperature differences in different areas of the liquid storage pipe 10, further improving overall heat dissipation efficiency.
[0060] Optionally, the distance between the multiple condensing ends 30b and the liquid storage tube 10 is gradually increased in the radial direction at different rates. Alternatively, the distance between the multiple condensing ends 30b and the liquid storage tube 10 is gradually increased in the radial direction at the same rate.
[0061] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The length of the multiple evaporation ends 30a extending into the liquid storage tube 10 is the same as the height of the liquid storage tube 10.
[0062] In this embodiment, the length of the heat pipe 30 extending into the liquid storage tube 10 refers to the vertical extension distance of the heat pipe 30 inserted into the liquid storage tube 10. Specifically, it can be achieved by welding or nesting a structure in which the end of the heat pipe 30 is flush with the bottom of the liquid storage tube 10, so that the evaporation end 30a of the heat pipe 30 is completely immersed in the heat source liquid. The height of the liquid storage tube 10 refers to the total length of the liquid storage tube 10 in the vertical direction, which can be achieved by using the axial dimension of a cylindrical or polygonal cavity. This parameter determines the volume of the heat source liquid and the effective contact range of the heat pipe 30.
[0063] Specifically, when the length of the heat pipe 30 extending into the liquid storage tube 10 is the same as the height of the liquid storage tube 10, the end of the evaporation end 30a of the heat pipe 30 is on the same plane as the bottom of the liquid storage tube 10, allowing the heat pipe 30 to extend completely vertically inside the liquid storage tube 10. In this state, when the heat source liquid fills the liquid storage tube 10, the entire surface of the evaporation end 30a is in direct contact with the liquid, avoiding the situation where part of the tube body is exposed above the liquid due to insufficient length. This design ensures a continuous and complete heat conduction path from the liquid to the heat pipe 30 by eliminating the non-contact area between the heat pipe 30 and the liquid, while avoiding the formation of stagnant areas at the end of the tube body when the liquid flows, allowing heat to be evenly transferred to the working fluid inside the heat pipe 30.
[0064] Compared to existing technologies, traditional radiators often employ a fixed insertion depth or a design that does not fully cover the height of the liquid storage tube 10, resulting in insufficient contact between parts of the heat pipe 30 and the liquid. For example, when the liquid level in the liquid storage tube 10 fluctuates due to flow rate changes, the end of the heat pipe 30 may intermittently detach from the liquid, causing fluctuations in heat transfer efficiency. This solution, by limiting the insertion length of the heat pipe 30 to match the height of the liquid storage tube 10, ensures that the evaporation end 30a is always fully submerged, regardless of whether the liquid is in a static or dynamic flow state. This eliminates the risk of interrupted heat transfer path, solves the problem of insufficient contact between the heat pipe 30 and the heat source liquid within the liquid storage tube 10, and maximizes the effective contact area of the evaporation end 30a of the heat pipe 30 within the liquid storage tube 10, thereby improving the heat absorption efficiency per unit time.
[0065] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The radiator also includes a first heat spreader 40, which is attached to the liquid storage pipe 10.
[0066] In this embodiment, the first heat spreader 40 refers to a plate-like structure with high thermal conductivity, specifically made of copper or aluminum. This structure serves as the heat transfer medium between the liquid storage tube and the heat dissipation fin assembly 20, directly transferring heat from the liquid storage tube to the heat dissipation fin assembly 20. The heat dissipation fin assembly 20 is a heat dissipation structure formed by stacking multiple metal sheets, specifically manufactured through stamping or welding processes to increase the contact area with air. This assembly receives uniformly distributed heat and accelerates heat dissipation through contact with the first heat spreader 40. The liquid storage tube 10 is cylindrical, and the first heat spreader 40 is a corresponding cylindrical shape, fitting and wrapping around the liquid storage tube 10 and abutting against the heat dissipation fin assembly 20.
[0067] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7The heat dissipation fin assembly 20 includes a plurality of heat dissipation fins 21 stacked together and two second heat exchange plates 22. Each heat dissipation fin 21 is connected to the two second heat exchange plates 22 at both ends. Each second heat exchange plate 22 is provided with a central mounting hole. The liquid storage pipe 10 and the first heat exchange plate 40 are both inserted through the central mounting hole.
[0068] In this embodiment, the stacked heat dissipation fins 21 refer to multiple fins arranged sequentially in a vertical direction. Specifically, they can be achieved by parallel stacking of thin aluminum or copper sheets, thereby increasing the heat dissipation surface area and improving heat dissipation efficiency. The second heat spreader 22 is a metal plate with high thermal conductivity, specifically formed from copper or aluminum plates, used to connect the two ends of each heat dissipation fin 21 and evenly distribute heat. The central mounting hole is a through hole located in the central region of the second heat spreader 22, specifically formed by stamping or milling processes, used to accommodate the passage of the liquid storage pipe 10 and the first heat spreader 40, ensuring the continuity of the heat conduction path.
[0069] The heat dissipation fins 21 are stacked to form a longitudinally extending heat dissipation surface. Second heat spreaders 22 are fixed to both ends of the fins, allowing heat to be uniformly transferred along the length of the fins through the second heat spreaders 22, eliminating localized temperature differences. A central mounting hole allows the liquid storage pipe 10 and the first heat spreader 40 to pass through the central area of the second heat spreader 22. The first heat spreader 40 transfers heat from the heat pipe 30 to the second heat spreader 22, which further diffuses the heat laterally to each heat dissipation fin 21, forming an annular heat conduction channel. Through the connection structure between the fins and the second heat spreader 22, heat is transferred laterally between the fins, reducing the temperature gradient between adjacent fins.
[0070] This application achieves uniform heat distribution in the heat dissipation fin assembly 20, improving heat dissipation efficiency; eliminates temperature gradients between fins through lateral heat conduction paths, enhancing overall heat dissipation stability; and the design of the central mounting hole ensures efficient thermal coupling between the liquid storage pipe 10 and the first heat spreader 40 and the second heat spreader 22, forming a multi-level collaborative heat dissipation structure.
[0071] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The heat sink also includes a mounting bracket 50 and a fan assembly 60. The mounting bracket 50 is connected to one side of the heat sink fin assembly 20, and the fan assembly 60 is mounted on the side of the mounting bracket 50 facing away from the heat sink fin assembly 20.
[0072] In this embodiment, the fixed bracket 50 refers to the support structure that supports the fan assembly 60. Specifically, it can be formed by welding a metal frame and fixed to the side edge of the heat sink fin assembly 20 with bolts. This structure provides stable support while isolating the transmission of mechanical vibration. The fan assembly 60 refers to the power device that generates forced airflow. Specifically, it can be an axial fan driven by a motor. Its installation position is limited to the plane of the fixed bracket 50 away from the heat sink fin assembly 20, so that the airflow direction forms a perpendicular angle with the extended plane of the heat sink fins 21.
[0073] When the heat source liquid flows through the storage pipe 10, heat is transferred to the heat sink fin assembly 20 through the heat pipe 30. At this time, the forced airflow generated by the fan assembly 60 penetrates the stacked gaps of the heat sink fins 21 in a vertical direction, accelerating the diffusion of heat on the fin surface. The fixed bracket 50, as an independent support unit, maintains the spatial separation between the fan assembly 60 and the heat sink fin assembly 20 to avoid resonance interference, and its rigid structure maintains the directional stability of the fan output airflow. This layout allows the airflow to cover the entire surface of the heat sink fins 21 at a uniform flow rate, eliminating local heat accumulation.
[0074] In some specific embodiments, the mounting surface of the fixed bracket 50 may be provided with guide grooves to optimize airflow distribution, and the fan assembly 60 may adopt a multi-set parallel blade structure to enhance airflow. A preset distance may be maintained between the extended end face of the heat dissipation fin assembly 20 and the fan outlet, for example, forming an airflow buffer area of 30-50 mm.
[0075] Compared to existing technologies, traditional heat sinks rely on natural convection, which limits heat dissipation efficiency. This solution, however, breaks down the thermal boundary layer through forced convection. Existing technologies lack directional airflow devices, making it impossible to create a continuous and stable airflow circulation path. This application achieves highly efficient forced heat dissipation while maintaining structural compactness through a spatial decoupling design between the fixed bracket 50 and the fan assembly 60.
[0076] Through the above technical solution, this application effectively enhances the airflow penetration capability of the heat dissipation fins 21, enabling the heat conducted by the heat pipe 30 to be quickly carried away from the heat dissipation area. The forced convection significantly improves the heat exchange rate on the fin surface, thereby solving the problem of overall performance degradation caused by insufficient heat dissipation efficiency in traditional radiators.
[0077] In one embodiment, please refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 The heat pipe 30 is designed in a U-shape or V-shape.
[0078] In this embodiment, the U-shape (inverted shape) refers to the arc-shaped bend at the top of the heat pipe 30, which can be achieved using a copper pipe bending process. This structure forms a symmetrical gas phase flow channel to promote condensate recirculation. The V-shape (inverted shape) refers to the sharp angle shape with two beveled sides at the top of the heat pipe 30, which can be achieved by welding two inclined pipe sections. This configuration expands the heat dissipation area in the vertical direction.
[0079] When the evaporator end 30a of the heat pipe 30 is immersed in the liquid storage pipe 10, the U-shaped structure forms symmetrically distributed vapor channels in the condensation section, allowing the liquid working fluid to flow back evenly along both pipe walls. The V-shaped design forms an expanded heating surface by tilting the pipe walls, increasing the contact area with the liquid storage pipe 10 within a limited installation space. Both geometric configurations enhance phase change heat transfer efficiency by changing the shape of the heat pipe 30. The U-shape is suitable for symmetrical heat dissipation scenarios, while the V-shape is adapted to compact space layouts.
[0080] This scheme constructs a multi-directional flow channel structure with a specific geometric shape, increases the effective heat exchange area under the same spatial conditions, and enhances the working fluid circulation driving force by optimizing the capillary pressure distribution, thereby achieving more efficient heat energy transfer.
[0081] This utility model also proposes a medical treatment device; please refer to [link / reference]. Figure 2 The medical treatment device includes an energy generator and a radiator. The energy generator is connected to the liquid storage pipe 10 of the radiator. The specific structure of the radiator is as described in the above embodiments. Since this medical treatment device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0082] This medical treatment device mainly consists of two key components: an energy generator and the aforementioned radiator. The energy generator and the radiator's reservoir pipe 10 are precisely connected. As the power source of the entire device, the energy generator stably generates and outputs the required energy, providing reliable power support for the treatment process. The generated energy is accurately transmitted to the radiator's reservoir pipe 10 through specific pipes or connecting devices. Upon receiving energy from the energy generator, the radiator utilizes its unique heat dissipation function to effectively reduce the heat generated during treatment, ensuring the device operates within a safe temperature range. This guarantees the smooth progress of medical treatment and the safety and comfort of the patient. This ingenious structural design and close collaboration between components enable the medical treatment device to demonstrate superior performance and wide applicability in practical applications, bringing new solutions and possibilities to the medical field.
