Each magnetic stimulation module includes a housing, a stimulation coil housed within the housing, and a rear cover on the back of the housing. The housing contains a heat dissipation assembly, including a cooling fan positioned on the same side as the stimulation coil. Between the housing and the rear cover are heat-conducting plates extending outwards on both sides. A U-shaped heat sink is mounted on the extended section of the heat-conducting plate, with a notch on one side to allow for adjustment of the mounting direction to expose either the front or rear air outlet.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cooling component for a magnetic stimulator. Background Technology

[0002] Current magnetic stimulators typically employ fixed cooling structures, limiting the flexibility of their air outlet direction. Traditional solutions often rely on unidirectional fans or liquid-cooled pipes for directional heat dissipation, or use semiconductor heat sinks directly attached to the coils. However, the direction of heat dissipation is constrained by the physical layout of the device. This design fails to meet the patient's needs for heat utilization in low-temperature winter environments. Waste heat generated by the magnetic stimulator coils is usually directly discharged into the environment, unable to be directed to the patient's skin, thus missing the opportunity to provide localized warmth. This can exacerbate patient discomfort, especially in hypothermic treatment settings. Utility Model Content

[0003] This invention proposes a cooling component for a magnetic stimulator, which solves the problem that existing technologies cannot meet the needs of patients in low-temperature environments during winter, thus achieving the purpose of utilizing the heat source.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A cooling assembly for a magnetic stimulator includes a power supply module and multiple magnetic stimulation modules connected by connecting wires; each magnetic stimulation module includes a housing, a stimulation coil disposed in the housing, and a back cover disposed on the back of the housing.

[0006] The housing is equipped with a heat dissipation assembly, which includes a cooling fan located on the same side as the stimulation coil. Between the housing and the rear cover, there is a heat-conducting plate extending outward on both sides. The heat-conducting plate has multiple heat-conducting channels. The air inlets of the heat-conducting channels correspond to the cooling fan, and the air outlets of the heat-conducting channels correspond to the front and rear sides of the extension section of the heat-conducting plate. The extension section of the heat-conducting plate is equipped with a U-shaped heat sink. A notch is opened on one side of the heat sink to allow the air outlet on the front or rear side to be exposed by adjusting the mounting direction of the heat sink.

[0007] Furthermore, the heat-conducting sheet is provided with heat-conducting ribs, and the side of the heat-conducting ribs away from the heat-conducting sheet is in contact with the stimulation coil.

[0008] Furthermore, the heat-conducting plate is also provided with an air inlet cap. The interior of the air inlet cap is designed to be through and conical. The conical constriction section is located at the air inlet, and the conical expansion section faces the cooling fan.

[0009] Furthermore, heat dissipation fins are provided on the heat sink on the same side as the notch.

[0010] Furthermore, the connecting line is provided with a deformation sleeve that can be bent and retain its deformed state.

[0011] Furthermore, an elastic band connects two adjacent heat-conducting sheets.

[0012] Furthermore, the stimulation coil has a microchannel design inside that guides cold flow for heat dissipation.

[0013] The beneficial effects of the technical solution provided in this application are as follows:

[0014] 1. The cooling component of this magnetic stimulator features a U-shaped heat sink mounted on the extension of the heat-conducting plate. A notch is opened on one side, allowing the air outlet to be selectively exposed on the front or rear side by rotating the mounting direction. For example, during winter treatment, the air outlet can be directed towards the patient's body surface to utilize waste heat for auxiliary warmth; in summer, it can be directed towards the external environment to enhance heat dissipation efficiency.

[0015] 2. The cooling components of this magnetic stimulator feature an air inlet aligned with the cooling fan in the heat conduction channel, ensuring efficient airflow through the extension section.

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1-4 A cooling assembly for a magnetic stimulator includes a power supply module 10 and multiple magnetic stimulation modules 20 connected by a connecting line 11. Each magnetic stimulation module 20 includes a housing 21, a stimulation coil 23 disposed in the housing 21, and a back cover 22 disposed on the back of the housing 21. The stimulation coil 23 has a microchannel design inside that guides cold flow for heat dissipation. Its core function is to enhance heat exchange efficiency: by guiding the cooling fluid to circulate in the microchannel, it directly absorbs the Joule heat generated when the stimulation coil 23 is working, forming a dual-path synergistic heat dissipation mechanism with external air cooling.

[0025] The outer casing 21 is provided with a heat dissipation assembly 30, which includes a cooling fan 31 located on the same side as the stimulation coil 23. Between the outer casing 21 and the rear cover 22, there is a heat-conducting plate 32 extending outward on both sides. The heat-conducting plate 32 has multiple heat-conducting channels. The air inlet of the heat-conducting channel corresponds to the cooling fan 31, and the air outlet of the heat-conducting channel corresponds to the front and rear sides of the extension section of the heat-conducting plate 32. The extension section of the heat-conducting plate 32 is equipped with a U-shaped heat sink 34. A notch 35 is opened on one side of the heat sink 34 to allow the air outlet on the front or rear side to be exposed by adjusting the mounting direction of the heat sink 34. A cooling fan 34 is fixed to the same side as the stimulation coil 23 to directly draw heat from the coil. A heat-conducting plate 35 is sandwiched between the outer shell 21 and the rear cover 22 and extends to both sides. The air inlet of its internal heat-conducting channel faces the air outlet of the cooling fan 34, forming a forced airflow path. The U-shaped heat sink 37 mounted on the extension section is oriented through a single-sided notch 38. If the notch faces forward or backward, the direction of the air outlet can be physically switched. The notch 38 acts as an airflow guide valve. By rotating the U-shaped heat sink 37, the front or rear air outlet is selectively exposed, while the other side is sealed by the heat sink. This directs waste heat to the patient's body surface to keep them warm in winter or cool them in summer. This process relies solely on the physical rotation of the U-shaped heat sink 37 to switch the airflow path. There is no need to modify the pipe structure or add power components. While maintaining the integrity of the airflow path, it meets the seasonal heat source directional utilization needs in a zero-energy manner.

[0026] In some embodiments, the heat-conducting sheet 32 ​​is provided with heat-conducting ribs 36, and the side of the heat-conducting ribs 36 away from the heat-conducting sheet 32 ​​contacts the stimulation coil 23. As a metal structure, the heat-conducting ribs 36 quickly absorb and transfer heat from the local high-temperature area of ​​the stimulation coil 23 to the main body of the heat-conducting sheet 32, compensating for the hot spots outside the coil not covered by the microchannel; by expanding the contact area through the multi-point distribution of heat-conducting ribs 36, the contact thermal resistance between the coil 23 and the heat-conducting sheet 32 ​​is reduced, avoiding heat accumulation that could lead to local overheating of the coil. Heat is transferred to the heat-conducting ribs 36 through physical contact, and the heat-conducting material of the ribs conducts the heat longitudinally to the base of the heat-conducting sheet 32; the heat-conducting sheet 32 ​​diverts the heat to the extension section and discharges it through the internal heat-conducting channels 36.

[0027] In some embodiments, the heat-conducting plate 32 is further provided with an air inlet cap 37. The interior of the air inlet cap 37 is designed to be through and conical, with the conical constriction section located at the air inlet and the conical expansion section facing the cooling fan 31. The conical expansion section increases the windward cross-sectional area, captures the scattered airflow from the cooling fan 31, compresses and delivers it to the constriction section, reducing airflow loss. The tapered structure of the constriction section accelerates the airflow and increases static pressure, enhancing airflow penetration and ensuring that more airflow efficiently enters the heat-conducting channel 36, alleviating the airflow attenuation problem caused by turbulence in traditional straight-through air inlets. The scattered airflow output by the cooling fan 31 is gathered and collected by the expansion section of the air inlet cap 37 and guided along the conical inner wall to the constriction section. When the airflow passes through the constriction section, it is accelerated and pressurized due to the reduced cross-sectional area, forming a high-speed, high-pressure airflow that is directionally injected into the air inlet of the heat-conducting channel 36.

[0028] In some embodiments, heat dissipation fins 33 are provided on the heat sink 34 on the same side as the notch 35. When the notch 35 of the U-shaped heat sink 34 is installed on the patient side, the heat dissipation fins 33 are located in the front air outlet area. By increasing the heat dissipation surface area, the heat exchange between the airflow and the fins is accelerated, and the efficiency of waste heat transfer to the patient's body surface is improved. The dense arrangement of the fins 33 generates turbulent disturbance to the airflow at the air outlet, breaks the boundary layer thermal resistance, avoids heat accumulation on the surface of the heat sink 34, and avoids the increase in air resistance at the reverse air outlet caused by adding fins.

[0029] In some embodiments, the connecting wire 11 is provided with a deformable sleeve 12 that can be bent and retain its deformable state. The deformable sleeve 12 is made of, but is not limited to, a highly ductile metal core or a shape memory polymer, allowing it to be manually bent and locked into shape, so that the connecting wire 11 can be fixed in a specific direction according to the needs of the treatment scenario and adjusted according to the patient's head shape.

[0030] In some embodiments, an elastic band 40 connects two adjacent heat-conducting sheets 32. The elastic contraction force of the elastic band 40 pulls the heat-conducting sheets 32 of adjacent magnetic stimulation modules 20 together, adapting to changes in the head circumference of different patients and preventing the device from becoming loose or displaced.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
