Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a xenon lamp heat dissipation system and a treatment handpiece. Background Technology

[0002] Intense pulsed light (IPL) therapy devices typically rely on xenon lamps to emit high-intensity light, which is then guided towards the skin via a light guide module. When the IPL acts on the skin, it raises the skin temperature, causing pain. Two coolers are usually placed on opposite sides of the light guide module to lower its temperature, which is then transferred to the skin to cool it down.

[0003] Xenon lamps generate significant heat during operation, which needs to be dissipated to ensure proper functioning. Simultaneously, the cooler has a cold side and a hot side. When the cooler is working, the cold side is in contact with the light guide module, while the hot side generates a large amount of heat. This heat also needs to be dissipated promptly to maintain the cooler's normal operation.

[0004] In existing technologies, a heat sink is typically used to dissipate heat from the xenon lamp, while a heat dissipation channel is used to dissipate heat from the hot surfaces of the cooler. Due to the structural characteristics of the product, the heat dissipation channel for cooling the cooler needs to pass through the heat sink, and a guide channel is provided on the heat sink to allow the coolant to flow through the guide channel to the heat dissipation channel. To dissipate heat from the hot surfaces of both coolers, two guide channels are required.

[0005] When drilling holes on the surface of a heatsink to create two flow channels, it is usually necessary to drill holes at multiple locations on the heatsink from a vertical position, and then seal the portions of the holes that do not require heatsink flow to form the two corresponding flow channels. This allows heatsink from one inlet to flow into two separate heat dissipation channels.

[0006] However, if too many parts are blocked, the cross-section of the flow channel will be reduced, affecting the flow rate of the heat sink; if too few parts are blocked, the heat sink will not flow easily at the blockage, thus affecting the heat dissipation effect. In addition, there are multiple right-angle bends in the flow path of the heat sink in the heat dissipation channel, and local water circulation can easily occur at these bends, which will also affect the heat dissipation effect. Utility Model Content

[0007] The main purpose of this invention is to propose a xenon lamp heat dissipation system and a treatment handpiece, which aims to improve the heat dissipation effect.

[0008] To achieve the above objectives, the xenon lamp heat dissipation system proposed in this utility model includes:

[0009] Xenon lamp body;

[0010] The first heat sink is provided with the xenon lamp body passing through it. The first heat sink has a straight flow channel penetrating its two surfaces. Each flow channel has an inlet and an outlet located below the inlet.

[0011] A light guide module, which is connected to the first heat sink and faces the xenon lamp body; and

[0012] The cooler includes a cold surface and a hot surface. The cold surface is attached to the light guide module, and the hot surface is provided with a first liquid cooling channel that communicates with the liquid outlet of the flow guide channel.

[0013] In one embodiment, two flow channels are formed within the first heat sink, and the two flow channels are arranged in a mirror-symmetrical manner within the first heat sink, with the liquid inlets of the two flow channels connected.

[0014] The number of the coolers is two, and each cooler has a first liquid cooling channel on its hot surface, and each first liquid cooling channel is connected to a flow guide channel.

[0015] In one embodiment, a second liquid cooling channel and a connecting channel are further formed within the first heat sink, the connecting channel connecting the first liquid cooling channel and the second liquid cooling channel, and the connecting channel being inclined relative to the extending direction of the second liquid cooling channel;

[0016] The xenon lamp body is inserted through the second liquid cooling channel.

[0017] In one embodiment, a liquid outlet channel is also formed within the first heat sink, and the second liquid cooling channel is connected to the liquid outlet channel. The liquid outlet channel is inclined relative to the extending direction of the second liquid cooling channel.

[0018] In one embodiment, the first heat sink has a mounting groove, and the xenon lamp body passes through the mounting groove;

[0019] The xenon lamp cooling system also includes a glass plate, which is sealed and covered at the opening of the mounting groove, and forms the second liquid cooling channel with the inner wall of the mounting groove.

[0020] In one embodiment, the xenon lamp body includes a xenon lamp tube and a first electrode and a second electrode disposed at both ends of the xenon lamp tube, and the first heat sink covers the xenon lamp tube;

[0021] The xenon lamp cooling system further includes a second heat sink and a third heat sink, the second heat sink covering the first electrode, the third heat sink covering the second electrode, and the first heat sink located between the second heat sink and the third heat sink.

[0022] In one embodiment, the flow channel is located at one end of the first heat sink near the third heat sink. The first heat sink also forms a liquid outlet channel, a second liquid cooling channel, and a connecting channel.

[0025] The cooler also includes a cover plate, which is sealed and covers the opening of the groove and encloses the inner wall of the groove to form the first liquid cooling channel.

[0026] In one embodiment, the groove is wavy in shape.

[0027] This utility model also proposes a treatment handpiece, including the aforementioned xenon lamp heat dissipation system.

[0028] In the technical solution of this utility model, the first heat sink can dissipate heat for the xenon lamp body, and the cooler can cool the light guide module. Simultaneously, through the connected flow channel and the first liquid cooling channel, the heat transfer fluid can flow from the first heat sink to the cooler, thereby dissipating heat from the hot surface of the cooler. The flow channel is a straight channel formed by drilling holes from one surface of the first heat sink towards another, without any bends. This avoids the need to block multi-segment flow channels formed by drilling holes at multiple locations on a vertical surface. The heat transfer fluid can easily flow through the flow channel into the first liquid cooling channel, improving the flow efficiency of the heat transfer fluid and thus enhancing the heat dissipation effect on the cooler.

[0040] This utility model proposes a xenon lamp heat dissipation system 100.

[0041] Please see Figures 1 to 4 In one embodiment of this utility model, the xenon lamp heat dissipation system 100 includes a xenon lamp body 1, a first heat sink 2, a light guide module, and a cooler 3; the xenon lamp body 1 passes through the first heat sink 2, and the first heat sink 2 forms a straight flow channel 21 that penetrates its two surfaces. The flow channel 21 has a liquid inlet and a liquid outlet located below the liquid inlet; the light guide module is directly opposite the xenon lamp body 1; the cooler 3 includes a cold surface and a hot surface. The cold surface is attached to the light guide module, and the hot surface is provided with a first liquid cooling channel 31 that communicates with the liquid outlet of the flow channel 21.

[0042] It should be noted that the first heat sink 2 is a metal block that can absorb the heat generated by the xenon lamp body 1 during operation, thereby dissipating heat for the xenon lamp body 1. The light guide module can directionally guide and control the light. During operation, the light guide module is in contact with the skin to guide the pulsed light onto the skin for treatment. The cooler can cool the light guide module so that the light guide module can simultaneously conduct the cold energy to the skin, reducing the high temperature and pain caused by the pulsed light irradiating the skin. Therefore, the light guide module also has a better thermal conductivity. In some embodiments, sapphire is used as the light guide module. The cooler is usually a TEC (thermal energy dissipation device). The TEC has a cold side and a hot side. During cooling, the cold side cools down and is in contact with the light guide module to conduct the cold energy to the skin, while the hot side heats up. At the same time, a first liquid cooling channel 31 is set on the hot side of the cooler, and a heat sink is used to assist the TEC cooling plate in heat dissipation. The heat sink can be water, ethylene glycol, propylene glycol, water-alcohol mixture, etc. The continuous flow of the heat sink can remove the heat from the cooler 3.

[0043] The flow channel 21 is formed by drilling holes in the first heat sink 2. Specifically, it is a straight channel formed by drilling holes from one surface of the first heat sink 2 towards the other, and then connecting to the first liquid cooling channel 31. The location of this drilled hole is the liquid inlet of the flow channel 21. The first heat sink 2 is a roughly rectangular metal block, which houses the xenon lamp body and is mainly used to dissipate heat from the xenon lamp body. The flow channel can be formed by drilling holes on the upper and lower surfaces of the first heat sink 2, or it can be formed by drilling holes on the left and lower surfaces.

[0044] In the technical solution of this utility model, the first heat sink 2 can dissipate heat for the xenon lamp body 1, and the cooler 3 can cool the light guide module. Simultaneously, through the connected flow channel 21 and the first liquid cooling channel 31, the heat transfer fluid can flow from the first heat sink 2 to the cooler 3, thereby improving the heat dissipation effect of the cooler 3. The flow channel 21 is a straight channel formed by drilling holes from one surface of the first heat sink 2 towards the other. Compared to existing technologies with non-curved holes, it eliminates the need for additional holes to be drilled and sealed, thus avoiding the negative impact on the flow efficiency of the flow channel that might result from sealing additional holes. The heat transfer fluid can easily flow through the flow channel 21 into the first liquid cooling channel 31, improving the heat dissipation effect.

[0045] Furthermore, in one embodiment of this utility model, please refer to... Figure 2 Two flow channels 21 are formed inside the first heat sink 2. The two flow channels 21 are arranged in a mirror symmetrical manner inside the first heat sink 2, and the liquid inlets of the two flow channels 21 are connected. Similarly, two coolers 3 are also provided, which are respectively set on the two opposite sides of the light guide module. Each hot surface is provided with a first liquid cooling channel 31, and each first liquid cooling channel 31 is connected to a flow channel 21.

[0046] Both flow channels 21 are formed by drilling holes in the first heat sink 2. Specifically, two inclined flow channels 21 are formed by drilling holes at the same position on the upper surface of the first heat sink 2 towards opposite sides on the lower surface, and then connecting to the two first liquid cooling channels 31 respectively. The position of the drilled holes on the upper surface is the liquid inlet of the two flow channels 21. The two flow channels 21 are arranged in a mirror-symmetrical manner within the first heat sink 2. The mirror-symmetrical arrangement of the flow channels 21 ensures that the flow path and velocity of the heat exchanger in the two flow channels 21 are basically the same, thereby making the flow path and velocity of the heat exchanger in the first heat dissipation channel basically consistent, making the heat exchange process of the heat exchanger more balanced, and further improving the heat dissipation efficiency. The two hot surfaces with the first liquid cooling channels 31 can also improve the heat dissipation effect of the cooler 3. Specifically, a hole is drilled on the upper surface of the first heat sink, facing diagonally downward to the left, to form a flow channel. Then, a hole is drilled at the same position on the upper surface, facing diagonally downward to the right, to form another flow channel. The liquid inlet of the two flow channels is the same, and the two liquid outlets correspond to the hot surfaces of the two coolers on both sides of the light guide module.

[0047] In some other embodiments, the two flow channels are formed by drilling holes vertically downwards on the left and right sides of the upper surface, and the holes on the two upper surfaces are connected by a T-connector, with the three ports of the T-connector connecting the holes on the two upper surfaces and the liquid inlet, respectively.

[0048] In some other embodiments, the two flow channels are formed by drilling holes on the left / right surfaces toward the lower surface.

[0049] In the comparative implementation, holes need to be drilled first on the upper surface of the heat sink, without penetrating the lower surface. Then, holes are drilled on the left / right sides corresponding to the depth of the holes on the upper surface, penetrating the other side. Next, holes are drilled on the left and right sides of the lower surface, connecting the through holes formed on the left and right sides. At this point, there are a total of 5 holes on the outer surface of the heat sink. Then, the two holes on the left and right sides need to be sealed, so that the holes on the upper surface connect to the two holes on the lower surface, forming two channels. When sealing the holes on the left and right sides, if too much is sealed, and the length of the sealing material is too long, exceeding the position of the downward channel, the area at the bend of the channel will be reduced, decreasing the flow rate of the heat sink. If the length of the sealing material is too short and does not reach the position of the downward channel, the heat sink will form a dead end at this point, reducing the flow efficiency of the heat sink.

[0050] In this embodiment of the solution, by directly drilling holes, only three holes need to be drilled on the surface to form two channels, without the need for sealing, thus avoiding the aforementioned technical problems that affect the flow speed or efficiency of the heat exchanger.

[0051] To improve heat dissipation performance, please refer to one embodiment of this utility model. Figure 2 and Figure 4The first heat sink 2 also forms a second liquid cooling channel 22 and a connecting channel 23. The connecting channel 23 connects the first liquid cooling channel 31 and the second liquid cooling channel 22. The connecting channel 23 is inclined relative to the extension direction of the second liquid cooling channel 22. The xenon lamp body 1 passes through a second liquid cooling channel 22.

[0052] The second liquid cooling channel 22 can quickly remove the heat from the first heat sink 2, thereby providing more efficient heat dissipation for the xenon lamp body 1. The coolant enters the first heat dissipation channel from the guide channel to dissipate heat from the hot surface of the cooler. In some embodiments, when the cooler is cooling, the temperature of the hot surface can be around 50 degrees Celsius. When cooling the hot surface, the coolant in the first liquid cooling channel also reaches a maximum temperature of around 50 degrees Celsius. However, when the xenon lamp body is heating, the temperature can reach around 1000 degrees Celsius. Therefore, the coolant used to cool the hot surface can continue to cool the first heat sink. By setting a second liquid cooling channel within the first heat sink, the coolant flows through the second liquid channel to directly cool the xenon lamp body, improving the heat dissipation efficiency of the xenon lamp body. The number of second liquid cooling channels 22 can be set according to the specific structure of the xenon lamp body 1. In this embodiment, the xenon lamp body 1 has two xenon lamp tubes, and correspondingly, two second liquid cooling channels 22 are provided. The two xenon lamp tubes of the xenon lamp body 1 are each inserted through a second liquid cooling channel 22, allowing the coolant to directly contact the xenon lamp tubes and provide a more direct cooling effect. Each of the two second liquid cooling channels 22 requires a corresponding connecting channel 23. The two second liquid cooling channels 22 are connected to the two first liquid cooling channels 31 via the connecting channels 23. This allows the heat exchanger to circulate within both the first liquid cooling channel 31 and the second liquid cooling channel 22, improving heat exchanger utilization and reducing heat exchanger consumption. The connecting channels 23 are inclined relative to the extension direction of the second liquid cooling channels 22. This inclination reduces the flow resistance of the heat exchanger at the channel connection points, allowing the heat exchanger to flow more smoothly from the first liquid cooling channel 31 to the second liquid cooling channel 22.

[0053] Furthermore, in one embodiment of this utility model, please refer to... Figure 2The first heat sink 2 also has a liquid outlet channel 24, which is connected to the second liquid cooling channel 22. The liquid outlet channel 24 is inclined relative to the extending direction of the second liquid cooling channel 22. By setting the liquid outlet channel 24, the heat sink can be discharged in one concentrated location, improving the flow efficiency of the heat sink. When two second liquid cooling channels 22 are set, the liquid outlet channel 24 can be set between the two second liquid cooling channels 22, and the liquid outlet ends of the two second liquid cooling channels 22 converge at the liquid inlet end of the liquid outlet channel 24. The location of the liquid outlet channel 24 between the two second liquid cooling channels 22 makes the pipe layout in the first heat sink 2 more compact and the space utilization rate higher. The inclined liquid outlet channel 24 also helps to guide the heat sink out. In this design, the flow path of the heat exchanger is as follows: it enters the two guide channels 21 through one inlet, then flows through the two guide channels 21 to the two first liquid cooling channels 31, then flows through the two connecting channels 23 to the two second liquid cooling channels 22, and finally flows out through the outlet channel 24, thereby carrying away the heat of the first heat sink 2 and the cooler, and realizing the heat dissipation of the cooler and the two xenon lamps.

[0054] Specifically, in one embodiment of this utility model, please refer to... Figure 2 The first heat sink 2 has a mounting groove, through which the xenon lamp body 1 passes. The xenon lamp cooling system 100 also includes a glass plate 4, which is sealed over the opening of the mounting groove and forms a second liquid cooling channel 22 with the inner wall of the mounting groove. The glass plate 4 is transparent glass, so that the light emitted by the xenon lamp tube can be emitted through the glass plate 4 to the light guide module, and then guided by the light guide module to achieve skin treatment.

[0055] It is understandable that the temperature of the electrodes at both ends of the xenon lamp will be very high during operation. Therefore, in one embodiment of this utility model, please refer to... Figure 1 The xenon lamp body 1 includes a xenon lamp tube and a first electrode and a second electrode located at both ends of the xenon lamp tube. A first heat sink 2 covers the xenon lamp tube. The xenon lamp heat dissipation system 100 also includes a second heat sink 5 and a third heat sink 6. The second heat sink 5 covers the first electrode, and the third heat sink 6 covers the second electrode. The first heat sink 2 is located between the second heat sink 5 and the third heat sink 6. Both the second heat sink 5 and the third heat sink are metal blocks. The thermal conductivity of the metal blocks can absorb the heat from the first electrode and the second electrode, reducing the temperature of the xenon lamp body during operation.

[0056] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 2A flow channel 21 is located at one end of the first heat sink 2 near the third heat sink 6. The first heat sink 2 also forms a liquid outlet channel 24, a second liquid cooling channel 22, and a connecting channel 23. The connecting channel 23 connects the first liquid cooling channel 31 and the second liquid cooling channel 22, and the second liquid cooling channel 22 connects to the liquid outlet channel 24. A third liquid cooling channel 61 is formed inside the third heat sink 6, and the third liquid cooling channel 61 connects to the liquid outlet end of the liquid outlet channel 24. The second liquid cooling channel 22 increases the contact area between the first heat sink 2 and the heat exchanger, thereby more efficiently dissipating heat for the xenon lamp body 1. The third liquid cooling channel 61 enhances the heat dissipation capacity of the third heat sink 6. Multiple channels are connected sequentially to allow the heat exchanger to flow, improving the utilization rate of the heat exchanger.

[0057] To improve heat dissipation, two of each of the following are configured: the flow channel 21, the first liquid cooling channel 31, the connecting channel 23, and the second liquid cooling channel 22. These two flow channels 21, two first liquid cooling channels 31, two connecting channels 23, two second liquid cooling channels 22, the liquid outlet channel 24, and the third liquid cooling channel 61 are sequentially connected to form a multi-channel heat dissipation structure. This allows the heat exchanger to absorb heat more efficiently during its flow. The heat exchanger flows into the two first liquid cooling channels 31 through the two flow channels 21, then through the two connecting channels 23 to the two second liquid cooling channels 22, converging at the liquid outlet channel 24 before flowing into the third liquid cooling channel 61. Finally, it flows out through the liquid outlet pipe 9, thus carrying away heat from the first heat sink 2, the light guide module, and the third heat sink 6. Furthermore, the two flow channels 21 are located at the end of the first heat sink 2 closest to the third heat sink 6, meaning that the liquid inlet and outlet of this multi-channel heat dissipation structure are at the same end, facilitating external piping layout and reducing assembly difficulty.

[0058] Specifically, in one embodiment of this utility model, the hot surface has a groove, and the cooler 3 also includes a cover plate. The cover plate seals the groove opening and surrounds the inner wall of the groove to form a first liquid cooling channel 31. The extended shape of the groove is the shape of the first liquid cooling channel 31. In this embodiment, the groove is a wavy groove, and the corresponding first liquid cooling channel 31 is wavy, thus increasing the contact area between the heat dissipation agent and the light guide module. In other embodiments, the groove can be set to other shapes according to the heat dissipation requirements of the light guide module.

[0059] Furthermore, in one embodiment of this utility model, please refer to... Figure 1The xenon lamp cooling system 100 also includes an inlet pipe 7 and an adapter 8. The adapter 8 is located at the inlet of the flow channel 21 and connects the inlet pipe 7 and the flow channel 21. The adapter 8 also allows the coolant to enter the flow channel 21 more smoothly. Furthermore, when two flow channels 21 are provided, the adapter 8 can evenly distribute the coolant into both flow channels 21, thereby ensuring that the coolant flow rate in both flow channels 21 is as consistent as possible. In addition, the two flow channels 21 can be connected to different types of inlet pipes 7, such as flexible hoses or rigid pipes, via the adapter 8.

[0060] This utility model also proposes a treatment handpiece, which includes the xenon lamp heat dissipation system 100 described above. The specific structure of the xenon lamp heat dissipation system 100 is as described in the above embodiments. Since this treatment handpiece 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.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
